Background technology
Waste gas refers to that the mankind are at the poisonous and hazardous gas produced and discharge in life process.Particularly chemical plant, steel plant, pharmaceutical factory, and coking plant and oil plant etc., the waste gas smell of discharge is large, serious environment pollution and affect health.
A lot of containing pollutant kind in waste gas, its physics and chemistry character is very complicated, and toxicity is also not quite similar.Containing sulfur dioxide, nitrogen oxide (NOx), hydrocarbon etc. in the waste gas that fuel combustion is discharged; Because industrial production is raw materials used different with technique, and discharge various different pernicious gas and solid waste, containing various component as heavy metal, salt, radioactive substance; The tail gas of motor vehicle emission contains the hydrocarbons such as lead, benzene and phenol.Exhaust emission atmospheric environment is one of the world's the most serious the most general environmental problem.
But, in existing waste gas purification process, DeGrain, use cost is very high, is unfavorable for long-run development, and one of them is very bad to the adsorption effect of waste gas, direct Producing reason merges not between waste gas and filtered fluid, also there is residual gas in waste gas, cause exhaust treatment efficiency low, have much room for improvement in uphill process.

Preferred further to the present invention, described lautertuns comprises closed cell body, is provided with the first screen pack in the upper end of cell body inside, lower end is provided with the second screen pack, be provided with osculum in the bottom of described Rose Box, top is provided with inlet opening, between described cell body and described filtrate tank, be provided with valve.
Preferred further to the present invention, described adsorption filter screen comprises adsorption layer and screen pack, and described adsorption layer active carbon and lime particle composition, described screen pack is double-layer filtering net.
The present invention compared with prior art, has following beneficial effect:
1, in order to improve the defect of prior art, the present invention includes purification casing, exhaust gas inlet is provided with in one end of purification casing, pure qi (oxygen) outlet is provided with at the other end, described exhaust gas inlet place is provided with gasing pump, gas transmission supercharging is carried out by gasing pump, waste gas is made to enter cleaned filtrate, in described purification casing, be provided with cleaned filtrate for this reason, described exhaust gas inlet, the setting position of described pure qi (oxygen) outlet is on the described cleaned filtrate water surface, the downward-sloping extension be connected with exhaust gas inlet is provided with in described purification casing, by extension, waste gas is transported to bottom, the escape pipe that spiral is arranged on described purification box house is provided with at the port of export of described extension, the tube wall of described escape pipe forms venthole, the setting of multiple like this aperture, not only can increase the separation transported out of waste gas, expand gas output and dispersion amount, and forming good fusion between cleaned filtrate to filter, in order to improve the mobility of cleaned filtrate, improving syncretizing effect simultaneously, agitator is provided with at described purification box house, the present invention makes to purify the cleaned filtrate of box house by the stirring of agitator and is in active state, like this and formed between waste gas and well merge, exhaust treatment efficiency raising.
2, in order to auto recycling time lengthening, the described purification casing in the present invention is provided with inlet and liquid outlet, is provided with lautertuns and filtrate tank, between described filtrate tank and inlet, is provided with infusion pump between described inlet and liquid outlet; By lautertuns, filtration treatment is carried out to filtered fluid, the impurity of inside is filtered, can not affect and continue to use.
3, on the roof of described purification casing, be provided with dividing plate vertically downward in the present invention, described dividing plate is provided with ventilation slot, in described ventilation slot, be provided with adsorption filter screen, between described dividing plate and described pure qi (oxygen) export, form ventilation duct, be provided with air-introduced machine in described pure qi (oxygen) exit; By air-introduced machine, air is drawn out of, and automatically by adsorption filter screen and ventilation duct, such air is purified again, improves purification efficiency.Adsorption filter screen described in the present invention comprises adsorption layer and screen pack, and described adsorption layer active carbon and lime particle composition, described screen pack is double-layer filtering net.Risen to the top of purification casing by the waste gas of cleaned filtrate in the present invention, directly do not go out from pure qi (oxygen) exit, form certain pressure, internal pressure raises, under the prerequisite that air-introduced machine is not opened, or under the power of air-introduced machine is less than the prerequisite of gasing pump power, cleaned filtrate automatic pressing can be gone out purify casing, form circulation, the power cost reducing work exports.Remaining foreign gas wherein in active carbon and lime particle energy absorbed air, screen pack plays filtration further, guarantees the clean degree of air.
As from the foregoing, the present invention improves the clean effect of adsorption filtration greatly.
In order to explain technical scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
