Abstract
The utility model relates to a waste gas treatment and purification device, which comprises a primary purification tower, a secondary purification tower and a fan capable of pressing gas from the primary purification tower to the secondary purification tower, wherein a second corrosion-resistant circulating water pump, a second spraying device and a second filtering filler device are arranged in the second purification tower, and a demisting device is arranged at the position of an outlet of the secondary purification tower. As the means of two-stage purification treatment is adopted, acid waste gas produced in an industrial production can be further subjected to purification treatment, so that finally discharged waste water and waste gas can be up to the atmospheric emission standard.
Description
Technical field
The utility model relates to the treatment of waste gas system, especially a kind of two stage treatment purifier to the acid waste gas that produced in production of polysilicon.
Background technology
Prosperity and development along with photovoltaic industry, increasing medium-sized and small enterprises begin crystalline silicon material is processed and handled, and most enterprise most when the silicon material is corroded all be to adopt the mixed liquor of nitric acid, hydrofluoric acid and hydrochloric acid to carry out the product corrosion, thereby will produce Main Ingredients and Appearance is the escaping gas of nitrogen oxide, a spot of hydrogen fluoride gas, a spot of hydrogen chloride gas and chlorine hydrogen silane, and the initial concentration of the sour gas that is produced is all at 150mg/m
3More than.And according to the requirement of " discharge standard of air pollutants ", when the aiutage height was 30m, the highest permission concentration of emission of secondary discharge standard NOx was 240mg/m
3, the highest permission rate of discharge is 4.4kg/h; The highest permission concentration of emission of secondary discharge standard HF is 9mg/m
3, the highest permission rate of discharge is 0.59kg/h; The highest permission concentration of emission of secondary discharge standard HCL is 100mg/m
3, the highest permission rate of discharge is 1.4kg/h, therefore, exhaust gas discharging concentration is respectively after the treatment and purification: NOX＜240mg/m
3, HF＜9mg/m
3, HCL＜100mg/m
3
At present, in order to reach this standard-required, processing mode to this type of sour gas on the market is to handle or other simple exhaust-gas treatment modes through the one-level wet purification, but, because the feature of a large amount of nitrogen oxide, hydrogen fluoride gas and the hydrogen chloride gas that are produced in process of production shows as burst, intermittent, and concentration is higher, so simple exhaust-gas treatment mode can't be real waste gas is improved comprehensively handled.
The utility model content
The technical problems to be solved in the utility model is: a kind of simple in structure, waste gas purifying efficiency is high, final toxic emission concentration is little exhaust-gas treatment purifier is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of exhaust-gas treatment purifier, comprise first class purification tower, secondary purification tower and gas can be pressed into blower fan in the secondary purification tower from the first class purification tower, be provided with the second corrosion-resistant water circulating pump, second spray equipment and the second filter packing device in the described secondary purification tower, the exit of described secondary purification tower is provided with takes off the mist device.
The beneficial effects of the utility model are, solved the defective that exists in the background technology, the mode that adopts secondary purification to handle can further be carried out purified treatment with the acid waste gas that is produced in the industrial production, makes last waste water and gas of discharging can reach the standard of airborne release.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Among the figure: 1, first class purification tower; 11, dewatering device; 2, secondary purification tower; 21, take off the mist device; 3, blower fan; 31, volume damper; 4, gauze filter.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of exhaust-gas treatment purifier as shown in Figure 1, comprise first class purification tower 1, secondary purification tower 2 and gas can be pressed into blower fan 3 in the secondary purification tower 2 from first class purification tower 1, described first class purification tower 1 is by the air inlet of pipeline connection blower fan 3, and described secondary purification tower 2 is connected by the gas outlet of pipeline with blower fan 3.
All be provided with corrosion-resistant water circulating pump, spray equipment and filter packing device in first class purification tower 1 described in the utility model and the secondary purification tower 2, the exit of described first class purification tower 1 is provided with dewatering device 11, and the exit of secondary purification tower 2 is provided with takes off mist device 21.
The utility model is provided with gauze filter 4 in order to guarantee the normal operation of spray equipment at the water circulating pump inlet, damages water pump and plug nozzle in case foreign material enter, and influence is used.The shower nozzle material is a RPP, through single injection-molded, and intensity height, long service life.
Cleaning principle of the present utility model is: acid waste gas is at first sucked in the first class purification tower 1 by blower fan 3, after waste gas is distributed by the water conservancy diversion distribution apparatus in the tower, contact processing with reverse direct intersection of absorbent solution, enter inner core filler zone then and carry out repeatedly repeatedly filler filtration of liquid phase reactor, make waste gas in tower, have the long time fully to filter contact, produce liquid film and spray generation mass transfer reaction, guarantee qualified discharge.Contain sour waste gas behind first class purification tower 1 abundant absorption cleaning, and dewatering device 11 through being provided with in the tower exit, after removing the water smoke in the system, be pressed into secondary purification tower 2 by blower fan 3 again, absorb and after the interception of multilayer filler absorbs processing through the multilayer spray once more at tower inner acidic waste gas and absorption liquid, guarantee qualified discharge, after the tower exit be provided with take off 21 demists of mist device after discharge drum discharging atmosphere.Waste water enters Sewage Disposal through pipeline, focuses on.
What describe in the above specification is the specific embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field after having read specification can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from the essence and the scope of utility model.
