Powder and formaldehyde trapping device and purifying method thereof

Abstract

The invention discloses a powder and formaldehyde trapping device and a purifying method thereof. The purifying method comprises the following steps of engaging a power source of an exhaust fan, forming negative pressure in a lower box body, sucking the waste gas into a water and mixing chamber from an air inlet, and enabling the waste gas to be in full contact with a water curtain and water mist; then, enabling the waste gas to pass under a second separating plate, penetrate out of water, and enter a water and air filtering chamber; in the ascending process, enabling the waste gas to encounter an inclined perforated water blocking plate, so as to automatically separate water and air; enabling air flow to quickly ascend, fully mix with negative oxygen ions, and enter a centrifugal filtering chamber; filtering by a filter element, and enabling the exhaust fan to exhaust clean air out of an air exhaust port. The purifying method has the beneficial effects that the fine dust PM2.5 (particulate matter 2.5) and formaldehyde in the air, and more than 80 types of organic matters and inorganic matters which are dissolvable in water can be quickly trapped; the purifying accuracy is high, the amount of clean air is large, the amount of consumables is small, the operation cost is low, the purifying device can be widely applied to the preventing and control of air pollution sources and the control of decoration pollution in medium and small production enterprises with low cost and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a dust and formaldehyde capture device and a purification method thereof. Background technique [0002] With the development of modern industrialization, there are more and more sources of air pollution, fine dust PM2.5 and formaldehyde are the most polluted and the most harmful. [0003] Although the air cleaning device in the prior art can play a certain role in air cleaning. But there are still the following deficiencies: (1) It is only effective for coarse dust and light pollution, and when PM2.5 exceeds the standard and the air is heavily or moderately polluted, it is powerless; (2) High power consumption and expensive consumables. The device that specifically catches dust and formaldehyde involved in the prior art also has the following disadvantages: small clean air volume, high noise, uncompact structure, high manufacturing cost, and limited scope of...

Problems solved by technology

But there are still the following shortcomings: (1) It is only effective for coarse dust and light pollution. When PM2.5 exceeds the standard and the air is heavily or moderately polluted, there is nothing to do; (2) High power consumption and expensive consumables

The devices for specifically capturing dust and formaldehyde involved in the prior art also have disadvantages such as small clean air volume, high noise, uncompact structure, high manufacturing cost, and limited scope of use.
