Problems solved by technology

But the existing product has the following disadvantages: 1. It must be used in a relatively sealed living room, and the air purification can be completed through hundreds of times of air circulation and filtration. Pollution; 2. Its purification core activated carbon filter has a short service life, and once it is saturated, it will cause secondary pollution
[0005] The popular ionization air purifier products on the market have the following deficiencies: 1. It must be used in a relatively closed room with no oil fume and high humidity, and the purification effect can only be achieved after a long period of continuous operation
This device still has the following deficiencies: 1, it still exists in a closed room and can be used, once the window is opened for ventilation, it will cause the problem of new air pollution in the air; 2, there are still escaping oxygen, SO 2 , NOx, etc. diffuse into the indoor air, causing harm to the human body
3. There are also problems such as filter element replacement

Embodiment 1

[0064] Embodiment 1: be used for the air cleaning device of the present invention of single bedroom

[0065] For 18-40m 2 The structure of the air cleaning device of the present invention in the living room is shown in the appendix figure 1 . The details are described as follows: Fresh air inlet fan 100, the air inlet is provided with a stainless filter to prevent dust and insects from entering, and a fan 1 is installed inside, and the air volume is 200m 3 / h, wind pressure > 300Pa, the air pipe 9 of the inner diameter 100mm of the fresh air that is sent into is connected with the fresh air inlet of the heat exchanger 17 of the ventilation exhaust device 103 with a heat exchanger arranged on the window sill or indoor, and the fresh air is connected with After the heat exchange of the exhaust air, the temperature difference between it and the indoor air decreases, and then it is connected to the inlet of the fresh air purifier, and the incoming fresh air first flows through t...

Embodiment 2

[0073] Embodiment 2: The air cleaning device of the present invention is suitable for multi-room use.

[0074] According to the process and equipment type of Example 1, the flow rate of the fan 1 is increased, the cross-sectional area of ​​the chromatographic filter beds at each level is increased, and the amount of filler is increased accordingly, so that a fresh air purification device for purifying the air flow can be produced. Embodiment 2 According to the process of Embodiment 1, the fan 1 with an air volume of 800m3 / h and a static wind pressure>300Pa will be used, and the heat exchanger 17 of the ventilation device 103 with a heat exchanger has a heat exchange area of ​​5m 2 , the air volume of exhaust fan 18 is 200m 2 , the cross-sectional area of ​​each chromatographic bed is expanded to 0.5m 2 , fill each chromatographic filter bed according to implementing 1 method, fresh air inlet wind bucket 100, box-type outdoor fresh air purifier 101, the size of fresh air pipel...

Embodiment 3

[0075] Embodiment 3: The air cleaning device of the present invention suitable for central air conditioning of large buildings. Outdoor fresh air is first filtered through large-scale fiber carrier chromatographic bed 201, and its filler is identical with embodiment 1, then flows through plate heat exchanger 202, after reclaiming 35-55% of energy taken away in exhaust air, its temperature rises in winter ( Then reduce in summer), then flow through the preheater, and its fresh air temperature should reach more than 5 degrees in winter, and the fresh air enters the fiber packing chromatographic bed 203 with humidifying net through the blower fan 204 again, and the chromatographic packing is the processing of the chemical fiber felt The honeycomb-type large-scale humidifying net 205, the fresh air flows through the fiber carrier chromatographic bed 206 with automatic regeneration liquid, and its filler is polypropylene fiber felt and polyester fiber felt loaded with the active sub...

Abstract

The invention relates to an air purifier based on the chromatography mode absorption filtration principle. The air purifier comprises a fan, a box, a multi-stage chromatography mode filtering bed disposed in the box. The chromatography filler filled in the multi-stage chromatography mode filtering bed is various fiber felt filler loaded with active substances, granulate absorbent filler and filler wrapping fine-grained absorbent in the gaps of fiber felt. The active substances, disinfector and catalyst loaded on the fiber felt eliminate the pollutants such as PM10, PM2.5 and PM0.3 granulate pollutants, bacteria, viruses, benzene series pollutants, TVOC and formaldehyde in indoor air. The air purifier is high in one-step purification efficiency, and the chromatography mode filtering bed is regenerative, long in service life and free of secondary pollution.

Description

【Technical field】 [0001] The invention belongs to the technical field of air purification. More particularly, the present invention relates to an air purification device based on the principle of chromatographic mode adsorption filtration. 【Background technique】 [0002] In recent years, air pollution in vast areas of our country has become increasingly serious. PM2.5 can inhale particulate matter and harmful gases in the atmosphere into the indoor air, damaging the health of residents. Using an air purifier to purify indoor air is a recognized effective way to improve indoor air quality. [0003] The current air purifiers can be divided into two categories, one is adsorption filter air purifier based on activated carbon adsorption; the other is based on air ionization technology, including low-temperature plasma technology, ion wind technology, high-voltage electrostatic Dust removal, olfactory oxygen purification, negative oxygen ion purification, photocatalyst and othe...
