Description
Technical Field
The invention relates to the technical field of air purification, in particular to a composite air purification device.
Background
Along with the continuous popularization and promotion of various furniture articles, more and more gas pollution gradually permeates into the drip of people's life, and along with the continuous improvement of people's living standard, people also are more and more high to the demand of indoor air quality. Accordingly, various air purifiers are gradually emerging in people's daily lives. Although the currently widely used activated carbon adsorption method has many advantages, a saturated adsorption state exists, the activated carbon needs to be replaced and regenerated, and another form of purification device adopts a chemical reaction to treat indoor air, under the action of a catalyst, almost all pollutants can be subjected to an oxidation-reduction reaction to be converted into harmless substances, but an important problem exists in the treatment of the pollutants through the chemical reaction, namely that a single pollutant has an extremely low concentration in the air, the catalytic degradation rate of the pollutant with the extremely low concentration is slow, and the pollutant is oxidized through photocatalysis through a plurality of intermediate steps to generate harmful intermediate products, so that secondary pollution is easily formed.
For example, the chinese patent with application number 201410463112.0 discloses an air purifier, which comprises a first purifier, a second purifier arranged on the first purifier, a third purifier arranged on the second purifier and a control panel for controlling the operation of the whole purifier, wherein the first purifier is provided with a roller support, the invention can use air purifiers of different sections according to the space, namely the size of a room, one air purifier can be opened when the room is small, three air purifiers can work independently without interference, and if one air purifier is broken, the other two air purifiers can be used continuously; can purify the indoor air of different space sizes, simple structure, convenient to use, the practicality is strong. Like the air purifier that application number 201611050692.6 published again, blast air and filter through setting up the clarifier body and locating fan and the filter core on the clarifier body to reach the effect of purification, further improve the inspiratory capacity of clarifier through the wind-collecting cover effect moreover, improve circulation efficiency.
Combining the above technical solutions and the practical problems, the currently widely used technical solutions have major drawbacks mainly reflected in the following aspects:
(1) most of the existing air purifiers adopt an adsorption mode for air purification, and the main problems of the purification working mode are that the actual filtration efficiency is not high, only solid particles in the air can be filtered, but effective filtration and absorption of chemical components in the air are difficult to carry out, and the actual filtration effect is reduced;
(2) for the current technical scheme, the purification effect is pursued too much on a single side, and for turbid gas, the effective purification effect cannot be achieved due to too short residence time in the purifier, which is slightly less for a filtration adsorption type purifier, but for a purifier based on catalytic oxidation, the influence is larger, and the corresponding purification effect cannot be achieved due to too short residence time of the gas;
(3) in the existing air purifier, the purification method is single, so the structure for treating the waste gas is relatively simple, for example, the treatment of indoor air is achieved only by adopting filtration adsorption or oxidation, the air purification effect is general, and the purification effect cannot be too high necessarily for achieving the corresponding purification purpose;
(4) the air to be purified is not pretreated, so that the filter inner core is easy to be contaminated by pollutants in a large area in the subsequent adsorption and purification process, and therefore, the filter inner core needs to be replaced regularly and frequently to achieve the corresponding purification effect.
