Description
Technical field
The utility model relates to a kind of emission-control equipment.
Background technology
At present, China has more than 1,100 in all kinds of colleges and universities, 15 of regular senior secondary school, and in 63 of junior middle schools, more than 30,000 of inspection bodies at different levels such as scientific research institutions, quality inspection, health and epidemic prevention, environmental monitoring, agricultural have formed a huge system.This intrasystem laboratory has large quantities of students, scientific research personnel and testing staff carrying out various experiments every day.Various instrument and equipments and miscellaneous chemicals and extremely toxic substance to be used during experiment, unavoidably poisonous and hazardous discarded object can be produced.Relevant department finds laboratory class environmental pollution source investigate: waste gas directly discharges, and seldom at the discharging gas port activated carbon adsorption unit or other treating apparatus is housed.Contain in these emissions a lot of severe toxicity, mutagenesis, teratogenesis shape, carcinogenic material, though not as good as industrial enterprise unit, this blowdown behavior that lacks supervision for a long time just constitutes potential threat in the mode of " many grains of sand piled up will make a pagoda " to surrounding enviroment aspect quantity and intensity.The waste gas that the laboratory produces has the volatile matter of sulfur-containing compound, nitrogen-containing compound, oxycarbide and hydrocarbon, halogen compounds and reagent etc.If be directly released in the atmosphere, the sulfur dioxide in the waste gas, nitrogen oxide can form acid rain in air, also directly polluted surrounding air.And school's chemical laboratory condition is poor, and lab space is little, does not have whole exhaust equipment and fume hood.In student experimenting when operation,, reagent opens wide everywhere and places, and swims in airborne waste gas, stimulates respiratory system, and the harm people's is healthy, and instrument service life is shortened in the corrosion and the damage of instrument and equipment in the accelerating chamber simultaneously.
Usually directly producing experiment poisonous, pernicious gas in the laboratory all requires to carry out in fume hood, high-temp waste gas is extracted in the acid gas absorption tower handles, (Φ 2m * 6m) diameter is big owing to material filling type acid gas absorption tower, highly big, from great, investment is big, be not suitable for being installed in the laboratory or roof, medium and small enterprises and institutions also cannot afford, so all adopted in line mostly or steal row's mode, have directly polluted surrounding air.And airduct is set between fume hood and the attic blower fan, and generally adopting the PVC material, pipeline is longer.Pernicious gases such as high temperature acid mist are met condensation and are formed that acid solution accumulates in the airduct and constantly enrichment in exclusion process, airduct is formed long-term corrosion, behind the airduct corrosion failure, drop onto on passageway or the corridor, concrete floor is eroded away pockmark, and the holdee is formed threat.Residual hydrofluoric acid foreign material are in the pipeline demolishing process or meet spark and easily produce blast in the pipeline.Domestic existing many are steamed the report that sour old pipeline sets off an explosion and causes the worker to die because of removing.
This just need a kind ofly can efficiently remove, and the laboratory is poisonous, the device of pernicious gas, is installed on the miniaturization device that the laboratory provides thorough treatment of laboratory waste gas.
The utility model content
The technical problem that the utility model solved provide a kind of simple in structure, be more suitable for the acid gas absorption machine installing and use in small-sized place such as laboratory.
