Description
Technical field
The invention belongs to field of environment protection equipment, relate to a kind of waste gas pretreatment purifier in particular.
Background technology
Atmosphere pollution is one of the most outstanding at present environmental problem of China.Wherein industrial waste gas is the important sources of atmosphere pollution.The most unmanageable in industrial waste gas is exactly organic exhaust gas, mainly comprises various hydro carbons, alcohols, aldehydes, acids, ketone and amine etc.They are mainly derived from the waste gas discharged in petroleum and chemical industry industry production process, and feature is that quantity is comparatively large, and content of organics fluctuation is large, flammable, have certain toxicity, and what have goes back foul smelling, and the discharge of CFC also can cause the destruction of ozone layer.Domestic dyeing hot melt adhesive applicators, PVC calender plastic cement, trimmer shaping and mill produce a large amount of organic exhaust gas in production heat process.After organic exhaust gas enters human body by respiratory tract and skin, can cause temporary and permanent lesion to organs and systems such as human body respiration, blood, livers, especially polycyclic aromatic hydrocarbon type organic can make human body directly carcinogenic.Organic exhaust gas, except causing direct atmosphere pollution, also can generate secondary pollution by the reaction of series of complex, one of main source becoming PM2.5 under the effect at sunshine.So the process of organic exhaust gas is imperative with purification.
Usually the technology adopted at process organic exhaust gas at present has absorption, absorption, condensation, UF membrane, high temperature incineration, catalytic combustion, biological oxidation, low-temperature plasma and photodissociation oxidation fission, makes it to generate CO2 and H2O and discharges.
But owing to containing a large amount of dust in organic exhaust gas, fiber grain etc., all obstruction is caused to above multiple method treatment effect in processing procedure, increase the load of cleaning equipment simultaneously, affect regulation effect, reduce the life-span of cleaning equipment, this part dust of current removing, the impurity such as fiber grain adopt filter screen directly to tackle usually, but organic waste is large-minded in factory, cannot shut down at any time and filter screen is changed, filter screen is often caused to block, cause resistance excessive, make fans load excessive, even cause filter screen damaged, dust, fiber grains etc. are crossed filter screen and are directly attached on electrodeless lamp tube.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of waste gas pretreatment purifier, the impurity such as dust, fiber grain in the organic exhaust gas that thorough solution produces factory processes at any time, avoids sticking the efficiency hindering photodissociation oxidation fission reaction on the processing system; Run, maintenance cost is low, process exhausted air quantity is large, and stable work in work, take up room little, cost performance is high.
For achieving the above object, the invention provides following technical scheme:
A kind of waste gas pretreatment purifier, comprises casing, is provided with exhaust steam passage in described casing, and be provided with sieves along on described exhaust steam passage, is provided with the first stage cleaning system for cleaned screen in described casing.
Preferred described first stage cleaning system comprises roller brush, home roll axle and secondary roll shaft, and in described sieves, two relative limits are controlled respectively around on home roll axle and secondary roll shaft, and roller brush is affixed on sieves.
On preferred described sieves, respective roller brush position is provided with cleaning roller, and described sieves is passed by the gap between roller brush and cleaning roller.
Be provided with second stage cleaning system in preferred described casing, the part of described roller brush is positioned at second stage cleaning system.
Be provided with catalytic liquid filter below preferred described second stage cleaning system, between described second stage cleaning system and catalytic liquid filter, be provided with motor-driven valve.
The catalytic liquid circulatory system is provided with between preferred described catalytic liquid filter and second stage cleaning system.
The sidewall of preferred described casing is provided with overflow pipe.
Fluid level control device is provided with in preferred described second stage cleaning system.
The another side of preferred described sieves respective roller brush is provided with full-automatic cleaner.
The beneficial effect that the present invention has is:
1, by arranging sieves on exhaust steam passage, the impurity such as dust, fiber grain is tackled, make to be blocked by the cleaning of first stage cleaning system to sieves the impurity be adsorbed on sieves simultaneously and departed from sieves by full-automatic cleaning, ensure the normal purifying property of sieves.
2, by the interaction of home roll axle and secondary roll shaft, make each position of sieves all clear up by full-automatic roller brush, remain that sieves is positioned at the clean of waste gas preliminary clearning system.
3, the catalytic liquid by placing in second stage cleaning system, realize the cleaning to full-automatic roller brush, catalytic liquid also can carry out Automatic clearance to adhesion substances on screen cloth simultaneously, ensures the cleaning of pretreatment system further, extends service life and the treatment effeciency of each parts.
4, by arranging catalytic liquid filter, can the solid adhesion substances be dissolved in catalytic liquid be filtered, then by catalytic cycle system catalytic liquid being led back in second stage cleaning system again and recycling, cost-saving.
5, the setting of overflow pipe and fluid level control device, can prevent the catalytic liquid liquid level in second stage cleaning system from controlling, prevent liquid level too high, affect the realization of preliminary clearning system range parameter.
