Description
Technical Field
The utility model relates to an air purification technical field, concretely relates to novel photocatalyst air purifier.
Background
With economic development and social progress, the environmental pollution problem becomes more serious, and the situation of air pollution becomes more severe. In airThe pollutants such as nitrogen oxides, VOCs and other organic and inorganic pollutants have great harm to human health. NO has a very strong affinity for hemoglobin, several hundred thousand times greater than oxygen. Once NO enters the blood, it drives oxygen out of the oxygenated hemoglobin, binding it firmly. For example, NO hemoglobin can be detected in the blood of a mouse exposed to an environment containing a small amount of NO. The tolerance for NO in the environment is now specified to be 25 mg/L. Volatile Organic Compounds (VOCs) are main pollutants in the atmosphere, and part of the volatile organic compounds come from the outdoors, mainly including industrial waste gas, motor vehicle tail gas, photochemical smog and the like; on the other hand, various volatile organic substances such as toluene, formaldehyde and the like can be released at normal temperature for decoration and decorative materials such as paint and solvents thereof, wood preservatives, coatings, plywood and the like. Due to the poor air mobility in the indoor environment, the accumulated contaminants pose serious harm to the human body through human breath and skin. Taking formaldehyde as an example, the human body is exposed to the formaldehyde for a long time, and the concentration is more than 0.1mg/m3In the formaldehyde atmosphere, dizziness and visual-audio retardation can occur, and in severe cases, the formaldehyde atmosphere can cause damage to respiratory systems, cardiovascular and cerebrovascular systems and the like. The mixed presence of multiple VOCs and chemical interaction with each other also increases the intensity of the hazard. Therefore, the improvement of the indoor air quality through the purification technology has important significance for the health of people and the treatment of VOCs.
Air purifier adopts the purification technique to purify the pollutant in the air commonly used equipment: the traditional treatment mode of air purification is purification technologies such as filtration, adsorption and ultraviolet lamp irradiation. The purifier adopts an adsorbing material (such as activated carbon) with high specific surface area and high porosity to adsorb harmful gases, can play a certain purifying role, but does not perform catalytic decomposition on the harmful gases because the adsorbing material mainly performs adsorption purification, and can generate secondary pollution and the like on air when an adsorbing saturated adsorbent is regenerated. The ultraviolet lamp only can be used under the unmanned condition because of simple ozone disinfection, and the ozone exceeding the standard in the air has certain harm to human bodies, and the strong oxidizing property of the ozone can also damage indoor furnishings. The photocatalytic technique used is mainly through TiO2Photocatalyst and ultraviolet light source. Due to TiO2The forbidden band width of the material is 3.2eV, the photoresponse range is in an ultraviolet region, the radiation utilization rate is low, and TiO is added2The recombination probability of the photon-generated carriers is high, so that the efficiency of photocatalytic degradation is greatly limited. Meanwhile, the ultraviolet mercury lamp used as an ultraviolet excitation light source can generate trace ozone under the action of oxygen in the air for a long time, potential safety hazards are caused, and in addition, the waste mercury lamp belongs to a pollution source, and a light source which is safe to use, free of pollution and long in service life is a necessary trend of the future photocatalytic air purifier industry.
The existing photocatalyst air purifier mainly has the following problems: 1) the existing purifier mostly adopts a single-layer filter plate; 2) the contact surface of the photocatalyst and harmful substances such as formaldehyde in airflow is not large, the contact time is not long enough, so that the catalytic oxidation effect is not thorough, the rate of the photocatalytic oxidation reaction is slow, and the light utilization rate is low.
