Embodiment 1

[0014] Embodiment 1. Use 10cm wide 150 mesh stainless steel wire mesh, tightly wound to form a diameter of 20cm, a cylindrical packing with a height of 10cm, installed in the cylindrical tower body, chemical absorption liquid is sprayed from the top, and the air to be purified enters from the bottom of the packing. The liquid is fully contacted and exchanged on the surface of the filler to purify the air. After testing, this type of air purifier has a removal rate of 99%, 98%, 96%, and 99% for sulfur dioxide, nitrogen dioxide, ozone, and formaldehyde in the air. .

Embodiment 2

[0015] Embodiment 2. be that the stainless steel of 0.2mm in diameter and the glass fiber of 0.2mm in diameter are made barrel wire mesh, carry out parallel winding again, make diameter 150cm, high 30cm cylindrical packing, be installed in the exhaust of coal-fired power plant In the pipeline, the lye is sprayed onto the filler from above, forming a liquid film on the surface of the filler, and the exhaust gas enters the filler from below, the gas and liquid are fully exchanged, nitrogen oxides and sulfur oxides are absorbed by the lye, and the emissions of nitrogen dioxide and sulfur dioxide can be reduced. The amount is reduced by more than 98%.

Embodiment 3

[0016] Embodiment 3. use 30cm wide 200 order stainless steel wire mesh, tightly wound to form diameter 50cm, high 30cm cylindrical packing, be installed in cylindrical tower body, be used for ethanol rectification, its rectifying effect and 3m high Raschig ring The effect of packing is equivalent, and 6% ethanol can be rectified to 93%.

Abstract

The invention relates to novel fluid-air exchange filler. The filler is formed by tightly winding or overlapping strip-shaped silk screens, and has the porosity of 86-95%, the bulk density of 660-760Kg / m<3>, and the specific area of 2000-3600m<2> / m<3>. The filler is dense in texture and uniform in pores, and can enable a fluid to form a uniform film on the surface of the filler to facilitate fluid-air exchange. When the novel fluid-air exchange filler is used in an air purifier, absorption liquid and polluted air are made to exchange sufficiently so as to remove pollutants for achieving the purpose of air purification. The novel fluid-air exchange filler can also be used for tail gas treatment and chemical rectification.

Description

technical field [0001] The invention is used for environmental protection and belongs to the technical field of environmental protection. Background technique [0002] With the emergence of large-scale smog weather, the harm of air pollution has received widespread attention from all walks of life. Air pollution has an increasing impact on people's health, and pollution control has become a social consensus. However, air pollution control is a long-term and huge systematic project. Experts estimate that China's current air pollution control will take at least 20 to 30 years. In order to solve the real health protection problems, many families choose to use indoor air purifiers to protect the indoor air quality of the family. Air purifiers began to enter the home in large numbers. [0003] The main causes of air pollution are industrial combustion, industrial emissions, vehicle fuel emissions and living facilities emissions. China's most authoritative air monitoring depar...
