According to the research report, as many as 4.3 million people died of kitchen air pollution in 2012, when will the harm caused by indoor air pollution stop? Maybe, you don't know that the air in your room every day is turbid, and the air you breathe every day has harmful gases that you have never expected. Let's follow 360 common sense.

室内污染物有哪些来源?

What are the sources of indoor pollutants?

1、有机污染物

1. Organic pollutants

甲醛

formaldehyde

室内甲醛主要来源于建筑材料、家具、各种粘合剂涂料、合成织物人造板等地方。甲醛是具有强烈刺激性气味的气体,是一种挥发性有机化合物,对人体健康的影响表现在刺激眼睛和呼吸道,造成肺、肝、免疫功能异常。

Indoor formaldehyde mainly comes from building materials, furniture, various adhesive coatings, synthetic fabric wood-based panels and other places. Formaldehyde is a kind of gas with strong irritant odor and volatile organic compounds. Its effect on human health is manifested in stimulating eyes and respiratory tract, causing abnormal lung, liver and immune functions.

苯及同系物甲苯、二甲苯

Benzene and its homologues toluene and xylene

苯及苯系物甲苯和二甲苯都为无色、有芳香气味的,以蒸气状态存在于空气中,在室内装修中,由于装饰装修材料选择不当或者施工工艺不合理,极易形成室内苯和苯系物的污染。甲苯、二甲苯其毒性主要是对中枢神经和植物神经有危害。国家卫生标准规定室内苯的最高允许浓度是每立方米不能超过2.4mg。

Benzene and its derivatives toluene and xylene are colorless and aromatic, and exist in the air in the state of steam. In the interior decoration, due to improper selection of decoration materials or unreasonable construction technology, it is easy to form indoor benzene and its derivatives pollution. Toluene and xylene are harmful to central nervous system and autonomic nervous system. According to the national health standard, the maximum allowable concentration of indoor benzene is no more than 2.4mg/m3.

挥发性有机化合物

Volatile organic compounds

挥发性有机化合物对人体影响主要是刺激眼睛和呼吸道,让人皮肤过敏,使人体产生头痛、咽喉痛、乏力等症状,挥发性有机化合物主要来自室内装饰材料日用化工产品、燃料等。

The effects of VOCs on human body are mainly eye and respiratory tract irritation, skin allergy, headache, sore throat, fatigue and other symptoms. VOCs mainly come from interior decoration materials / daily chemical products, fuels, etc.

2、无机污染物

2. Inorganic pollutants

重金属

heavy metal

空气中的重金属是存在于大气颗粒物当中的,而粒径小于10μm的大气颗粒物(可吸入颗粒物PM10)更含有高含量的重金属。据报道,大约75%~90%的重金属分布在PM10中,且粒径越小,重金属含量越高。

The heavy metals in the air exist in the atmospheric particles, and the atmospheric particles (PM10) with particle size less than 10 μ m contain more heavy metals. It is reported that about 75% - 90% of heavy metals are distributed in PM10, and the smaller the particle size is, the higher the heavy metal content is.

铅、镉、铬、汞、砷等是常见的有毒污染物其可溶物对人体有明显危害,皮肤长期接触铬化合物可引起接触性皮炎或湿疹,过量的铅、镉、汞、砷对人体神经、内脏系统造成危害,特别是对儿童生长发育和智力发育影响较大,重金属元素主要来自家具内墙涂料和壁纸等,室外来源的由燃煤燃油及化工生产排放的颗粒进入室内也会带来重金属污染。

Lead, cadmium, chromium, mercury and arsenic are common toxic pollutants. Their soluble substances have obvious harm to human body. Long-term contact with chromium compounds on skin can cause contact dermatitis or eczema. Excessive lead, cadmium, mercury and arsenic can cause harm to human nerve and visceral system, especially to children's growth and intellectual development. Heavy metal elements mainly come from furniture, interior wall coating and wall Paper and other outdoor sources from coal-fired fuel oil and chemical production of particles into the indoor will also bring heavy metal pollution.

气态无机污染物

Gaseous inorganic pollutants

氨气为无色,有强烈刺激性气味的气体,极易溶于水,对接触的组织有腐蚀和刺激作用,氛的刺激性强,对眼、喉、上呼吸道作用快,但其释放期也快,对人体危害较小。室内空气中氛气存在的主要原因是由于冬季施工时,建筑施工中使用的混凝土外加剂、室内装饰材料中的添加剂和增白剂。

Ammonia is a colorless gas with a strong irritant odor, which is very soluble in water and has corrosive and irritant effects on the contacted tissues. The atmosphere is highly irritant and has fast effects on eyes, larynx and upper respiratory tract, but its release period is also fast, which is less harmful to human body. The main reason for the existence of atmosphere in the indoor air is the concrete admixture used in the construction, the additive and whitening agent in the interior decoration materials.

还包含从外界大气进入室内的有害气体。往往是由于地理位置缘故。如:硫氧化物碳的氧化物,主要是一氧化碳(二氧化碳不属于大气污染物),还有氮氧化物。

It also contains harmful gases entering the room from the outside atmosphere. It is often due to geographical location. For example: the oxides of sulfur oxide carbon, mainly carbon monoxide (carbon dioxide does not belong to air pollutants), and nitrogen oxides.

3.生物污染

3. Biological pollution

生物污染主要是由居室中较潮湿霉变墙壁、生活垃圾、宠物、室内花卉、地毯、空调、家具等产生的污染,主要污染物为细菌、病菌和尘蜡等。通过咳嗽、打喷嚏等喷出的流感病毒、结核杆菌和链球菌等生物污染物。

Biological pollution is mainly caused by damp and moldy walls, domestic garbage, pets, indoor flowers, carpets, air conditioners, furniture, etc. the main pollutants are bacteria, bacteria, dust and wax, etc. Through coughing, sneezing, and other spewing influenza virus, tuberculosis and Streptococcus and other biological pollutants.

室内空气治理该怎么办?

How to deal with indoor air treatment?

空气净化器能够吸附、分解或转化各种空气污染物(一般包括PM2.5、粉尘、花粉、异味、甲醛之类的装修污染、细菌、过敏原等),能够在现有的条件下,有效的提高室内空气清洁度的产品,所在近年来,深受用户青睐。

Air purifier can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, peculiar smell, formaldehyde and other decoration pollution, bacteria, allergens, etc.), and can effectively improve indoor air cleanliness under existing conditions. In recent years, it is favored by users.

净化器工作原理:

Working principle of purifier:

空气净化器主要由马达、风扇、空气过滤网等系统组成,其工作原理为:机器内的马达和风扇使室内空气循环流动,污染的空气通过机内的空气过滤网后将各种污染物清除或吸附,某些型号的空气净化器还会在出风口的加装负离子发生器(工作时负离子发生器中的高压产生直流负高压),将空气不断电离,产生大量负离子,被微风扇送出,形成负离子气流,达到清洁、净化空气的目的。

The air purifier is mainly composed of motor, fan, air filter screen and other systems. Its working principle is: the motor and fan in the machine make the indoor air circulate and flow, the polluted air passes through the air filter screen in the machine, and then all kinds of pollutants are removed or adsorbed. Some models of air purifier will also be equipped with negative ion generator in the air outlet High pressure produces DC negative high pressure), which ionizes the air continuously and produces a large number of negative ions, which are sent out by the micro fan to form negative ion air flow, so as to achieve the purpose of cleaning and purifying the air.

根据净化需求来分,空气净化器可以分为:

According to the purification requirements, the air purifier can be divided into:

(1)纯净化型。如果位于室内湿度较适中的地区,或者对空气质量要求不太高,则选购纯净化型的空气净化器就满足需求了。

(1) Pure type. If it is located in an area with moderate indoor humidity, or the air quality requirements are not too high, the purchase of purified air purifier will meet the demand.

(2)加湿净化型。如果是位于较干燥的地区、经常开空调被空调抽湿而造成室内空气干燥、或者对空气质量要求较高,则选购一台带有加湿净化功能的空气净化器,将是最适合的选择。LG未来名人空气净化器还具有自然加湿的技术,采用科技手段来实现水的汽化,通过风车式或者盘式过滤器旋转,将有害物质留在托盘中消除,只排放超细和清洁的水分子到空气中。

(2) Humidification and purification type. If it is located in a dry area, the air conditioner is often turned on to be wet by the air conditioner, resulting in the drying of indoor air, or the air quality requirements are high, then choosing an air purifier with humidification and purification function will be the most suitable choice. LG's future celebrity air purifier also has the technology of natural humidification, which uses scientific and technological means to realize water vaporization. Through the rotation of windmill or disc filter, harmful substances are left in the tray to be eliminated, and only superfine and clean water molecules are discharged into the air.

(3)智能型。如果喜欢自动化操作、智能监控空气质量、或者体现高贵品味、或者用来送礼需要更体面,则选购一台智能型的空气净化器便是最佳选择。

(3) Intelligent. If you like automatic operation, intelligent monitoring of air quality, or embodiment of noble taste, or need to be more dignified for gift giving, an intelligent air purifier is the best choice.

(4)车载型。如果是用于轿车内空气净化,需要专门净化汽车异味、汽车甲醛等车内污染,并能够专门放置于车内的空气净化器,所以,最优选择为车载型空气净化器。

(4) Vehicle type. If it is used for car air purification, it needs to specially purify car odor, car formaldehyde and other car pollution, and can be placed in the car air purifier. Therefore, the best choice is car air purifier.

(5)桌面型。即放置于桌面,净化桌面周围一定范围内的空气,保护桌面附近人的健康的空气净化器。如果经常坐在电脑前、办公桌前、或者书桌前,但是所处的室内面积不小,或者是公共场所,自己掏钱买一台大型的空气净化器并不划算,也不时尚,则桌面型的空气净化器就是较好的选择。

(5) Desktop type. That is, put it on the desktop, purify the air around the desktop within a certain range, and protect the healthy air purifier near the desktop. If you often sit in front of a computer, a desk, or a desk, but the indoor area is not small, or in a public place, it is not cost-effective or fashionable to buy a large air purifier at your own expense, the desktop type air purifier is a better choice.

(6)大中型。主要适用于面积较大的室内场合,如家内大厅、高级银行办公室、高级行政办公室、重要的演讲厅会议厅、高级酒店、医院、美容院、幼儿园等场合。

(6) Large and medium-sized. It is mainly suitable for large indoor occasions, such as home hall, senior bank office, senior administrative office, important lecture hall, conference hall, senior hotel, hospital, beauty salon, kindergarten and other occasions.

(7)中央空调系统型。主要适用于安装了中央空调、或者有天花板的单一房间或者多个房间一起净化的情况。

(7) Central air conditioning system type. It is mainly suitable for single room or multiple rooms with central air conditioning or ceiling.

空气净化器选购你知多少?

How much do you know about air purifier?

1、选对购买渠道

1. Select the right purchase channel

购买空气净化器时,建议尽量在大型商场、电器商店、品牌专卖店和主流电子商务网站等正规渠道购买。

When buying air purifier, it is suggested to try to buy it in large shopping malls, electrical stores, brand stores, mainstream e-commerce websites and other regular channels.

截至2013年,空气净化器品牌、功能、性能、外观设计和价格都有很大的区别,让人眼花缭乱。建议消费者根据自身实际需求选购产品,并不是功能越多越好。

As of 2013, the brand, function, performance, appearance design and price of air purifier are quite different, which makes people dazzled. It is suggested that consumers choose products according to their actual needs, not that more functions are better.

如,对于需要防护PM2.5的消费者,建议选择PM2.5净化能力突出的空气净化器。新装修家庭可以侧重去除甲醛和甲苯能力突出的空气净化器。

For example, for consumers who need to protect PM2.5, it is recommended to select air purifier with outstanding purification capacity of PM2.5. Newly decorated families can focus on the removal of formaldehyde and toluene outstanding ability of the air purifier.

2、过滤技术

2. Filtration technology

颗粒污染物过滤技术主要是HEPA滤网,HEPA滤网质量参差不齐,一些小品牌的滤网虽然具有较高的过滤效率,但是阻力大,能效比比较低,而且很容易堵塞,寿命较短,一般建议选用带有静电驻极的深度容尘HEPA滤网,静电驻极技术使得无纺布纤维带有正负电,有效捕捉空气中的颗粒物,很多HEPA滤网都号称具有静电驻极技术,但是由于技术原因很多滤网的驻极电荷在较短的时间内会衰减的很快,导致过滤效率降低。

Particle Pollutant filtration technology is mainly HEPA filter, the quality of HEPA filter is uneven. Although some small brand filters have high filtration efficiency, they have high resistance, low energy efficiency ratio, and are easy to block, with short service life. It is generally recommended to select a deep dust containing HEPA filter with electrostatic electret, which makes the non-woven fiber with positive and negative electricity, effectively catching dust Many HEPA filters claim to have electrostatic electret technology to catch particles in the air. However, due to technical reasons, the electret charge of many filters will decay rapidly in a short time, resulting in the reduction of filtration efficiency.

可以选择市面上的如3M静电驻极的HEPA滤网,与3M口罩采用同样静电驻极技术,永久保证驻极效率不衰减。

The HEPA filter screen on the market, such as 3M electrostatic electret, can be selected. The same electrostatic electret technology is used with 3M mask to permanently ensure the efficiency of electret does not decline.

3、关注适用面积或颗粒物洁净空气量(CADR)

3. Pay attention to applicable area or clean air volume of particles (Cadr)

空气净化器净化能力的强弱,主要是由适用面积和颗粒物洁净空气量(CADR:提供的洁净空气的速率)决定,两者之间的关系为:适用面积=CADR×0.1。对其它污染物的净化能力,应和适用面积相结合。 [8]

The purification capacity of the air purifier is mainly determined by the applicable area and the clean air volume of particles (Cadr: the rate of clean air provided). The relationship between the two is: applicable area = Cadr × 0.1. The purification capacity of other pollutants shall be combined with the applicable area. [8]

4、能效比和能效等级

4. Energy efficiency ratio and energy efficiency grade

空气净化器通常是长期连续使用的,能效比作为衡量空气净化器净化能力与电力消耗的重要指标,值得大家关注。能效比和能效等级越高,代表空气净化器越节能,使用成本越低。

The air purifier is usually used continuously for a long time. As an important indicator to measure the purification capacity and power consumption of the air purifier, the energy efficiency ratio deserves our attention. The higher the energy efficiency ratio and the energy efficiency level, the more energy-saving the air purifier is, the lower the use cost is.

5、臭氧释放量

5. Ozone release

臭氧作为强氧化剂具有一定的净化能力,但对人体是有伤害的。国家对空气净化器臭氧释放量有强制性安全要求,限定在≤5×10-6%(臭氧具有鱼腥味)。

As a strong oxidant, ozone has a certain purification ability, but it is harmful to human body. The state has mandatory safety requirements for ozone emission from air purifiers, which is limited to ≤ 5 × 10-6% (ozone has fishy smell).

想要室内空气健康, 要从哪几方面努力坚持?

Want indoor air to be healthy, what respect should we strive to insist on?

快速净化:空气净化器运行初期,建议在最大风量档运行至少30分钟,再调至其它档位,以达到快速净化空气效果。

Fast purification: at the initial stage of air purifier operation, it is recommended to operate at the maximum air volume level for at least 30 minutes, and then adjust to other levels to achieve fast air purification effect.

净化污染:使用空气净化器去除室外大气污染物时,建议尽量保持门窗处于相对密封状态,避免室内外空气大量交互流通造成的净化效果下降。长时间使用,应注意阶段性换气通风。

Purification pollution: when using air purifier to remove outdoor air pollutants, it is recommended to keep doors and windows in a relatively sealed state as far as possible to avoid the reduction of purification effect caused by a large number of indoor and outdoor air interactive circulation. Long time use, should pay attention to the stage ventilation.

装修净化:若用于净化装修后带来的室内气态污染(如甲醛、笨、甲苯等)建议有效通风后再使用。

Decoration purification: if it is used to purify indoor gas pollution (such as formaldehyde, benzene, toluene, etc.) after decoration, it is recommended to use it after effective ventilation.

保证效果:定期更换或清洁过滤器,保证空气净化器的净化效果,同时避免失效过滤器吸附的污染物二次排放。

Guarantee effect: replace or clean the filter regularly to ensure the purification effect of the air purifier, and avoid the secondary emission of pollutants adsorbed by the failed filter.

长期未用:长期未使用的空气净化器再次开机前,应检查其内壁清洁程度和过滤器状态,做好相应的清理工作,必要时更换过滤器 。

Long term unused: before the air purifier that has not been used for a long time is turned on again, its inner wall cleanliness and filter status shall be checked, and corresponding cleaning work shall be done, and the filter shall be replaced if necessary.

室内空气污染,不容忽视,想要健康呼吸,呼吸的健康,就要从室内健康着手,做好室内空气的治理与净化。

Indoor air pollution can not be ignored. If you want to breathe healthily, you should start from indoor health and do a good job in indoor air treatment and purification.
