A composite air purification device

Abstract

The invention discloses a combined type air purification device. The combined type air purification device comprises a purification case, a primary dust collection device, a photo-catalytic oxidation device and a tail end filtering device, wherein the primary dust collection device and the photo-catalytic oxidation device are fixedly mounted in the purification case in sequence, and the photo-catalytic oxidation device is connected with the tail end filtering device through a guide pipe; and an air inlet pipe is fixedly mounted on the outer side of the end, close to the primary dust collection device, of the purification case, and an air outlet pipe is fixedly mounted on the outer side of the tail end filtering device. Through the combined type purification device, rapid and effective purification can be achieved while the purification flow rate is decreased, and the actual treatment efficiency is improved indirectly; and chemical catalytic purification methods are adopted mostly so that wastage of purification consumables can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a composite air purification device. Background technique [0002] With the continuous popularization and promotion of various furniture items, more and more gas pollution has gradually infiltrated into people's lives. With the continuous improvement of people's living standards, people's demand for indoor air quality is also increasing. high. Therefore, various air purifiers gradually appear in people's daily life. Although the currently widely used activated carbon adsorption method has many advantages, there is a saturated adsorption state, and the activated carbon needs to be replaced and regenerated, while another form of purification device uses chemical reactions to treat indoor air. It can make almost all pollutants undergo oxidation-reduction reactions and turn them into harmless substances, but there is an important problem in dealing with pollutants through ...

AI Technical Summary

Problems solved by technology

[0005] (1) Most of the current air purifiers use the adsorption method for air purification. The main problem of this purification mode is that the actual filtration efficiency is not high, and it can only filter solid particles in the air. The chemical components contained in it are difficult to effectively filter and absorb, reducing the actual filtering effect;

[0006] (2) For the current technical solution, the pursuit of purification effect is too one-sided. For turbid gas, it is difficult to achieve effective purification effect if the time spent in the purifier is too short. For purifiers, the impact is slightly smaller, but for purifiers based on catalytic oxidation, this impact is relatively large, and it is difficult to achieve the corresponding purification effect if the gas residence time is too short;

[0007] (3) In the existing air purifiers, the way of purification is relatively simple, so the structure of its treatment of exhaust gas is relatively simple, such as only using filtration, adsorption or oxidation to achieve the treatment of indoor air, for the purification of air The effect is average, and in order to achieve the corresponding purification purpose, the purification effect must not be too high;

[0008] (4) There is no pretreatment of the air that needs to be purified, so that in the subsequent adsorption and purification process, the filter core is more likely to be contaminated with pollutants in a large area. Therefore, in order to achieve the corresponding purification effect, the filter must be replaced regularly and frequently The inner core can achieve the corresponding purification effect
