Embodiment approach

[0049] According to a preferred embodiment of the present invention, the method is performed in an air purification device, the air purification device being the air purification device of the present invention, and the method includes:

[0050] Such as figure 1 As shown, the air to be purified ( figure 1 The air to be treated containing particulate matter, gaseous pollutants, etc.) is sent to the air purification device, wherein the air to be purified is guided by the fan 3 through the pre-filter 2 to remove particulate matter, and then the particulate matter-removed air Dehumidification is performed by the dehumidification unit 4, the air dehumidified by the dehumidification unit 4 is purified by the purification unit 1, and then the purified air is sent to the humidification unit 6 for humidification as required, wherein the purification unit 1 passes The auxiliary heating unit 5 heats.

[0051] The present invention provides the application of the air purification method of t...

Embodiment 1

[0055] (1) The air to be treated contains 10mg / m 3 The relative humidity is 35%, and the air to be treated is removed by the particulate matter pre-filter 2 under the action of the fan 3;

[0056] (2) The air from which the particulate matter is removed passes through the dehumidification unit 4, which is an evaporator. The water vapor in the air condenses on the evaporator to reduce the humidity of the air, and the relative humidity of the air is 5%;

[0057] (3) At the same time, the auxiliary heating unit 5 heats the purification unit 1, raising the temperature of the purification unit 1 to 35°C, the auxiliary heating unit 5 is a condenser, and the distance between the auxiliary heating unit 5 and the purification unit 1 is 5 cm;

[0058] (4) The dehumidified air passes through the purification unit 1. The adsorption catalyst particle carrier of the purification unit 1 is activated carbon, and the catalytic active component on the surface of the carrier is 2.0 wt% MnO 2 , MnO loade...

Embodiment 2

[0061] (1) The air to be treated contains 2.5mg / m 3 Formaldehyde, 15mg / m 3 The relative humidity of carbon monoxide is 25%, and the air to be treated is removed by the particulate matter pre-filter 2 under the action of the fan 3;

[0062] (2) The air from which the particulate matter is removed passes through the dehumidification unit 4, which is an evaporator. The moisture in the air condenses on the evaporator to reduce the humidity of the air, and the relative humidity of the air is 10%;

[0063] (3) At the same time, the auxiliary heating unit 5 heats the purification unit 1, raising the temperature of the purification unit 1 to 45°C, the auxiliary heating unit 5 is a condenser, and the distance between the auxiliary heating unit 5 and the purification unit 1 is 0 cm, that is, auxiliary There is no distance between the heating unit 5 and the purification unit 1;

[0064] (4) The dehumidified air passes through the purification unit 1. The adsorption catalyst particle carrier of ...

Abstract

The invention relates to the air purification field and particularly provides an air purification device. The air purification device comprises a pre-filtering screen, a dehumidification unit and a purification unit which are sequentially arranged in the air flowing direction; the pre-filtering screen is used for trapping particulate matter in air; the dehumidification unit is used for removing humidity in air; the purification unit is used for purifying air passing through the dehumidification unit; a blower for guiding air to flow is arranged on the upstream side of the dehumidification unit. The invention further provides an air purification method and application of the air purification method. The air purification method comprises the following steps: removing particulate matter in air to be humidified; dehumidifying air from which particulate matter is removed; under the heating condition, purifying the dehumidified air to oxidize gaseous pollutants in air into carbon dioxide. According to the air purification method, owing to the dehumidification-catalytic purification coupling action, the catalytic effect of a catalyst is greatly improved, the service life of the catalyst is greatly prolonged, and accordingly, the operation and maintenance costs are reduced.

Description

Technical field [0001] The invention relates to an air purification device and an air purification method and their application in household appliances with air purification functions. Background technique [0002] The presence of carbon monoxide in enclosed spaces such as indoors and motor vehicles can have a huge negative impact on the enclosed space environment and human health. For example, the north is dry in winter and the indoor stove is burning, the carbon monoxide produced by the incomplete combustion of gas water heaters, the carbon monoxide present in the exhaust gas of automobiles, and the enclosed spaces such as ships will also produce carbon monoxide. The current market and product functions have not paid much attention to the harm of carbon monoxide. The use of a filter screen has almost no effect on carbon monoxide, and the activated carbon screen has a poor adsorption effect on carbon monoxide and is easily saturated with adsorption, causing secondary pollution....
