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

A kind of novel gas-liquid exchanges filler
Technical field
The present invention is used for environmental protection, belongs to environmental technology field.
Background technology
Along with the appearance of extensive haze weather, air-polluting harm receives the extensive concern of various circles of society.Air pollution is increasing on the impact that people are healthy, and pollution administration also becomes social consensus.But air contaminant treatment is a great system engineering for a long time, and expert estimates that the air pollution treatment of present stage of china at least needs 20 to three ten years.In order to solve the healthy protect problem of reality, many family selection indoor air cleaners, protection family IAQ.Air purifier starts to enter family in a large number.
Air-polluting main cause is caused to be facilities exhaust in industrial combustion, industrial discharge, vehicle fuel discharge and life.The air detection department of China most authority---China Environmental Monitoring General Station issues monitoring result and represents: haze composition (major air pollutants) in all parts of the country is: PM2.5, sulfur dioxide, nitrogen dioxide, ozone.The bacterium that indoor air pollutants somebody habitat environment produces, virus, decorated house produces the organic matter such as formaldehyde, benzene.
The design of conventional air cleaners just removes solid grain contamination, the PM2.5 that namely it has often been said by filtering.Some clarifier utilizes active carbon to absorb formaldehyde, limited efficiency, because its just absorption, again can be discharged in air, can not thoroughly remove by desorb.For harm people healthy maximum poisonous gas sulfur dioxide, nitrogen dioxide, ozone etc., like water off a duck's back.
Theoretical according to molecular complex, the chemical pollutant in air can neutralize them by chemical composition, reduction reaction, they is changed into harmless even benefit materials, thoroughly removes.For reaching this object, the environment that a chemical absorbing liquid fully contacts with contaminated air, exchanges must be had.Traditional chemical absorbing tower, because packing efficiency is low, complex structure, energy consumption is high, and separative efficiency is low, cannot be miniaturized.
For this reason, we have invented a kind of new packing, this filler parallel tight winding of banded silk screen or superposition are formed, and porosity is 86-95%, and bulk density is 660-760Kg/m 3, specific area is 2000-3600m 2/ m 3.The fine and close hole of this filler is even, and liquid can be made to form uniform film at filling surface, is conducive to gas-liquid and exchanges.For in air purifier, absorbing liquid and dusty gas fully exchanged thus removes pollutant, reaching the object purified air.Small indoor air purifier is produced with this filler, respond well through testing.For people provide one from the subenvironment of contaminated air harm, greatly protect that people's is healthy.
Summary of the invention
In order to improve gas-liquid exchange efficiency, Beijing Yuzhufeng Technology Co., Ltd. has carried out great many of experiments, and the filler of checking various material, has finally invented this new packing.The fine and close hole of this filler is even, and liquid can be made to form uniform film at filling surface, is conducive to gas-liquid and exchanges.For in air purifier, absorbing liquid and dusty gas fully exchanged thus removes pollutant, reaching the object purified air.Small indoor air purifier is produced with this filler, respond well through testing.
Technical scheme of the present invention manufactures the close filler of matter.This filler parallel tight winding of banded silk screen or superposition are formed, and porosity is 86-95%, and bulk density is 660-760Kg/m 3, specific area is 2000-3600m 2/ m 3.The silk screen diameter of new packing is the stainless steel wire of 0.01-1mm, synthetic fibres, glass fiber are made into alone or in combination, and the silk of knitmesh can be monofilament, also can be multiple thread strands combination, can be circle silk also can be flat filament.
The filler even pore distribution made, provides larger specific area, exchanges, gas and liquid can be made fully to exchange at shorter stroke, reach separation object for gas-liquid.
For purification of air, small and exquisite, efficient, practical small size air cleaner can be produced.For family, office space, when air pollution, protection people's is healthy.
For fuel plants exhaust emissions, alkali lye and tail gas can be made fully to exchange, make the sulfur dioxide in tail gas, nitrogen dioxide is fully absorbed, greatly reduce the discharge of pollutant.
For chemical industry rectifying column, this filler has the theoretical cam curve of super common fillers far away, and separative efficiency is high, can reduce tower body height, improves rectification efficiency, reduce energy consumption.
Embodiment
The embodiment 1. wide 150 order stainless steel cloths of 10cm, closely be wound diameter 20cm, the cylindrical pad of high 10cm, be installed in cylindrical tower body, chemical absorbing liquid sprays from above, and air to be clean enters below filler, gas-liquid fully contacts exchange at filling surface, by purification of air, entered test, this type air purifier reaches 99%, 98%, 96%, 99% respectively to the clearance rate of the sulfur dioxide in air, nitrogen dioxide, ozone, formaldehyde.
Embodiment 2. is the stainless steel of 0.2mm and diameter with diameter is that tubbiness silk screen made by 0.2mm glass fibre, carry out wound in parallel again, make diameter 150cm, the cylindrical pad of high 30cm, be installed in the exhaust duct of coal-burning power plant, alkali lye is sprayed onto from above on filler, form liquid film at filling surface, waste gas enters filler from below, and gas-liquid fully exchanges, the discharge capacity of nitrogen dioxide and sulfur dioxide, by alkali liquor absorption, can be reduced by more than 98% by nitrogen oxide, oxysulfide.
The embodiment 3. wide 200 order stainless steel cloths of 30cm, are closely wound diameter 50cm, the cylindrical pad of high 30cm, be installed in cylindrical tower body, for ethanol rectifying, its rectification effect is suitable with the high Raschig ring filler effect of 3m, can the ethanol of 6%, rectifying is 93%.
