Description
技术领域technical field
本实用新型属于空气净化装置，具体涉及一种能引入氧气的带有光触媒的空气净化装置。The utility model belongs to an air purification device, in particular to an air purification device with a photocatalyst capable of introducing oxygen.
背景技术Background technique
近年来，空气污染问题日益严重，室外PM2.5污染问题使得人心惶惶，室内空气污染同样不容乐观，装修污染严重超标，甲醛、TVOC、二手烟、霉菌等不断危害人体健康。老百姓对空气质量越来越重视，因此空气净化器及新风系统受到广泛关注。In recent years, the problem of air pollution has become more and more serious. The problem of outdoor PM2.5 pollution has made people panic. The indoor air pollution is also not optimistic. The pollution of decoration has seriously exceeded the standard. People are paying more and more attention to air quality, so air purifiers and fresh air systems have received widespread attention.
空气净化器核心组件主要是三层滤网：1.初效滤网，用于拦截大颗粒悬浮物；2.活性炭网，用于吸附甲醛等；3.HEPA滤网，用于过滤PM2.5等。室内空气从进风口进入空气净化器，通过三层滤网净化空气，之后从出风口排出洁净空气。这样循环过滤室内空气，达到空气净化的目的。问题在于活性炭吸附甲醛等污染物很容易达到饱和，会造成二次污染，需要常常更换滤网，增加人力物力成本。而且使用空气净化器必须得关紧门窗，防止室外污染物进入室内，但是长时间之后，由于没有新鲜空气进入，室内空气中氧气含量降低，会使人感到不适。The core component of the air purifier is mainly three-layer filter screen: 1. Primary filter screen, used to intercept large particles of suspended matter; 2. Activated carbon screen, used to absorb formaldehyde, etc.; 3. HEPA filter screen, used to filter PM2.5 Wait. Indoor air enters the air purifier from the air inlet, purifies the air through a three-layer filter, and then discharges clean air from the air outlet. In this way, the indoor air is circulated and filtered to achieve the purpose of air purification. The problem is that the adsorption of pollutants such as formaldehyde by activated carbon is easy to reach saturation, which will cause secondary pollution, and the filter screen needs to be replaced frequently, which increases the cost of manpower and material resources. Moreover, when using an air purifier, the doors and windows must be closed tightly to prevent outdoor pollutants from entering the room. However, after a long time, because there is no fresh air entering, the oxygen content in the indoor air will decrease, which will make people feel uncomfortable.
新风系统由新风机和管道配件组成，室外空气通过新风机净化导入室内，室内空气通过管道排出。新风机主要由过滤网和全热交换器组成：过滤网和空气净化器的滤网一样，目的在于净化室外空气中的污染物；全热交换器是一种含有全热交换芯体的新风、排风换气设备，室外过滤后的新风和室内污浊的排风分别流经换热器芯体时，由于气流分隔板两侧气流存在着温差和蒸汽分压差，两股气流通过分隔板时呈现传热现象，引起全热交换过程，使进入室内的新风回收了排风的能量，达到节能换气的目的。新风系统问题在于不能净化室内空气，只能排出，而为了回收排风能量节能而使用全热交换器，其体形大且芯体的成本高，整个新风系统安装复杂麻烦。The fresh air system is composed of a fresh fan and pipe fittings. The outdoor air is purified and introduced into the room through the fresh fan, and the indoor air is discharged through the pipe. The fresh air fan is mainly composed of a filter and a total heat exchanger: the filter is the same as the filter of the air purifier, and its purpose is to purify the pollutants in the outdoor air; the total heat exchanger is a fresh air with a total heat exchange core. Exhaust and ventilation equipment, when outdoor filtered fresh air and indoor dirty exhaust air flow through the heat exchanger core respectively, due to the temperature difference and steam partial pressure difference in the airflow on both sides of the airflow partition plate, the two airflows pass through the partition The heat transfer phenomenon occurs when the panels are connected, causing a total heat exchange process, so that the fresh air entering the room recovers the energy of the exhaust air, and achieves the purpose of energy saving and ventilation. The problem with the fresh air system is that it cannot purify the indoor air, but can only discharge it. In order to recover the exhaust air energy and save energy, a total heat exchanger is used, which has a large body and high cost of the core, and the installation of the whole fresh air system is complicated and troublesome.

具体实施方式Detailed ways
以下结合说明书附图对本实用新型做进一步说明。Below in conjunction with accompanying drawing, the utility model is further described.
如图1所示的能引入氧气的带有光触媒的空气净化装置，包括室内进风口1、室内出风口2，室内进风口1与室内出风口2之间设有光触媒网3，在光触媒网3之前还设有室外进风口4，室外进风口4配置风量调节阀5用以调节室外进风口的风量。尤其是，室外进风口4、室内进风口1并列设置。室外进风口4、室内进风口1与室内出风口2之间设有位于光触媒网3前侧的第一初效过滤网6、位于光触媒网3前侧的第一高效粒子空气过滤器7（高效粒子空气过滤器，是英文High Efficiency Particulate Air filter的缩写，简称HEPA）。室外进风口4的内侧设有第二初效过滤网8、第二高效粒子空气过滤器9。室内出风口2的内侧设有风机10。该空气净化装置还包括氧气检测传感器及控制器，控制器依据氧气检测传感器检测到的室内氧气含量来控制风量调节阀开启或者关闭。The air purification device with photocatalyst that can introduce oxygen as shown in Figure 1, comprises indoor air inlet 1, indoor air outlet 2, is provided with photocatalyst net 3 between indoor air inlet 1 and indoor air outlet 2, in photocatalyst net 3 An outdoor air inlet 4 was also provided before, and the outdoor air inlet 4 is equipped with an air volume regulating valve 5 to adjust the air volume of the outdoor air inlet. In particular, the outdoor air inlet 4 and the indoor air inlet 1 are arranged side by side. Between the outdoor air inlet 4, the indoor air inlet 1 and the indoor air outlet 2, the first primary filter screen 6 positioned at the front side of the photocatalyst net 3 and the first high-efficiency particle air filter 7 (high efficiency) positioned at the front side of the photocatalyst net 3 are arranged. Particulate air filter is the abbreviation of English High Efficiency Particulate Air filter, referred to as HEPA). The inner side of the outdoor air inlet 4 is provided with a second primary filter 8 and a second high efficiency particulate air filter 9 . The inner side of the indoor air outlet 2 is provided with a fan 10 . The air purification device also includes an oxygen detection sensor and a controller, and the controller controls the opening or closing of the air volume regulating valve according to the indoor oxygen content detected by the oxygen detection sensor.
使用时，将氧气检测传感器置于室内，氧气检测传感器与控制器可以通过电缆连接或者无线通讯，室外进风口可以根据氧气检测传感器测得的氧气含量控制风量调节阀调节风量。When in use, the oxygen detection sensor is placed indoors, the oxygen detection sensor and the controller can be connected by cable or wireless communication, and the outdoor air inlet can control the air volume regulating valve to adjust the air volume according to the oxygen content measured by the oxygen detection sensor.
正常空气中氧气含量约为21％，最小的允许氧气含量为19.50%，小于19.50%时人会感到不适，因此设置控制器的氧气含量区间为19%-20%。当氧气检测传感器检测出氧气含量大于20%时，关闭室外进风口，此时室内空气从室内进风口进入，依次流经第一初效过滤网、光触媒网、第一高效粒子空气过滤器被过滤净化，从室内出风口排出洁净空气。当氧气含量降低，小于19%时，打开室外进风口，室外空气从室外进风口进入，依次流经第二初效过滤网、第二高效粒子空气过滤器过滤净化后与室内进风口进入的空气融合，再依次流经第一初效过滤网、光触媒网、第一高效粒子空气过滤器被进一步过滤净化，后从室内出风口排出氧气含量较高的洁净空气,直至氧气含量达到标准。The oxygen content in normal air is about 21%, the minimum allowable oxygen content is 19.50%, people will feel uncomfortable when it is less than 19.50%, so the oxygen content range of the controller is set to 19%-20%. When the oxygen detection sensor detects that the oxygen content is greater than 20%, the outdoor air inlet is closed. At this time, the indoor air enters from the indoor air inlet and flows through the first primary filter, the photocatalyst net, and the first high-efficiency particle air filter to be filtered. Purify, discharge clean air from the indoor air outlet. When the oxygen content is lower than 19%, open the outdoor air inlet, and the outdoor air enters from the outdoor air inlet, and flows through the second primary filter, the second high-efficiency particle air filter, and the air entering the indoor air inlet after being filtered and purified. Fusion, and then flow through the first primary filter, photocatalyst net, and first high-efficiency particle air filter to be further filtered and purified, and then clean air with high oxygen content is discharged from the indoor air outlet until the oxygen content reaches the standard.
该空气净化装置不需要将室内污浊空气排出，而是不断循环净化室内空气，当室内氧气含量小于设置数据时引入室外空气，令室外空气和室内空气交汇融合，传热传质，不需要像新风系统一样为了回收排出空气中的能量而使用全热交换器。The air purification device does not need to discharge the indoor dirty air, but continuously circulates and purifies the indoor air. When the indoor oxygen content is lower than the set value, the outdoor air is introduced, so that the outdoor air and the indoor air merge and fuse, heat and mass transfer, and do not need fresh air. The system also uses a total heat exchanger in order to recover the energy in the exhaust air.
该空气净化装置用光触媒代替活性炭，利用空气中的氧分子及水分子将所接触的甲醛等有机物转换为无污染的水和二氧化碳，具有极强的杀菌、除臭、防霉、净化空气功能，不会产生二次污染。而且，光触媒作为一种催化剂自身不起变化，理论上有效期非常长久，维护费用低。The air purification device uses photocatalyst instead of activated carbon, and uses oxygen molecules and water molecules in the air to convert organic matter such as formaldehyde into non-polluting water and carbon dioxide. It has strong sterilization, deodorization, mildew resistance and air purification functions. No secondary pollution will be produced. Moreover, as a catalyst itself, photocatalyst does not change, and theoretically has a very long period of validity and low maintenance costs.
该空气净化装置，可以制成移动式结构，也可如图所示安装固定在吊顶饰面板11的上侧。The air cleaning device can be made into a mobile structure, and can also be installed and fixed on the upper side of the suspended ceiling decorative panel 11 as shown in the figure.
