The utility model adopts following technical scheme to realize:
A kind of emission-control equipment; It is characterized in that; This device is made up of upper strata spray district 4, packing area 3, lower floor spray district 2 and aeration zone, bottom 1 from top to bottom successively; Aeration zone, said bottom 1 is provided with air intake 7 and mixture export 9; Boring aeration pipe 14 UNICOMs that said air intake 7 is inner with aeration zone, said bottom; The sidewall in said lower floor spray district 2 is provided with the exhaust gas entrance 5 that is used for the air-introduced machine outer with being arranged on device and links to each other, be used for nutrient solution inlet 6, the lower floor's spray liquid inlet 10 that links to each other with device external nutrition liquid intake pipeline and be used for and clean water inlet 12 that the outside clean water pipeline of device links to each other, is filled with biologic packing material in the said packing area 3, and packing area 3 and lower floor spray and distinguish the carriage 17 that is provided with between 2 in order to the support filler; The sidewall in spray district, said upper strata 4 is provided with upper strata spray liquid inlet 11; Its top is provided with steam vent 16, and its inside is evenly distributed with spiral nozzle 13, and said mixture export 9, lower floor's spray liquid inlet 10 link to each other with a circulating pump respectively with upper strata spray liquid inlet 11.
Further, be provided with steam(-)coil 15 in the aeration zone, said bottom 1, said steam(-)coil 15 and steam inlet 8 UNICOMs that are arranged on aeration zone, said bottom 1 lateral wall.
Compared with prior art, the emission-control equipment of the utility model will ideally combine as the activated sludge process and the biological filtering tower combined working technology of method of wastewater treatment, compact conformation, and floor space is little, and operational management is convenient, and energy consumption is low; To the special efficacy microorganism of the pollutant kind of petroleum chemical industry waste gas screening and cooperate the effect of nutrient solution can accomplish thorough degraded down, realize the innoxious discharging of organic exhaust gas to organic exhaust gas; The unique texture form of equipment can absorb the hydrophilic and hydrophobic contaminant in the organic exhaust gas and hold back completely, for next step biodegradation of waste gas creates conditions.
Description of drawings
Fig. 1 is the structural representation of the utility model emission-control equipment.
The specific embodiment
Through facing the description of embodiment down; To help public understanding the utility model more; But can't be regarded as restriction by the concrete embodiment that the applicant is given to the utility model technical scheme, any definition to parts or technical characterictic change and/or to overall structure do form but not the conversion of essence all should be regarded as the protection domain that technical scheme limited of the utility model.
As shown in Figure 1; The emission-control equipment of the utility model; Whole advantages of integrated biological filtering tower combined working and aeration tank; Rely on special efficacy microorganism wherein and add nutrient solution and accomplish biodegradation organic exhaust gas; This device is made up of upper strata spray district 4, packing area 3, lower floor spray district 2 and aeration zone, bottom 1 from top to bottom successively; Aeration zone, said bottom 1 is provided with air intake 7 and mixture export 9, boring aeration pipe 14 UNICOMs that said air intake 7 and aeration zone, bottom 1 are inner, nutrient solution inlet 6, the lower floor's spray liquid inlet 10 that the sidewall in lower floor spray district 2 is provided with the exhaust gas entrance 5 that is used for the air-introduced machine outer with being arranged on device and links to each other, be used for linking to each other with device external nutrition liquid intake pipeline and be used for and install the clean water that links to each other of outside clean water pipeline enter the mouth 12; Be filled with biologic packing material in the said packing area 3; Be provided with in order to support the carriage 17 of filler between packing area 3 and the lower floor spray district 2, the sidewall in spray district, said upper strata 4 is provided with upper strata spray liquid inlet 11, and its top is provided with steam vent 16; 2 inside, lower floor spray district are evenly distributed with spiral nozzle 13; Mixture export 9, lower floor's spray liquid inlet 10 link to each other with a circulating pump respectively with upper strata spray liquid inlet 11, are provided with steam(-)coil 15 in the aeration zone, bottom 1, said steam(-)coil 15 and steam inlet 8 UNICOMs that are arranged on aeration zone, said bottom 1 lateral wall.
