Abstract
The utility model relates to a waste gas treatment system for a smelting furnace. The waste gas treatment system for the smelting furnace comprises a plurality of suction hoods, wherein the suction hoods are connected with a plurality of cyclone de-dusters through pipelines; the cyclone de-dusters are connected with an induced draft fan through the pipelines; the induced draft fan is communicated with a wet purifier; the wet purifier is communicated with a chimney; the wet purifier is sequentially connected with a sediment water tank, a water collection basin and a coagulating sedimentation tower; the coagulating sedimentation tower is communicated with the sediment water tank and a sewage basin. The waste gas treatment system for the smelting furnace has good treatment effect on waste gas; the generated sewage can be recycled; the production cost of the enterprise can be reduced.
Description
Technical field
The utility model relates to technical field of waste gas treatment, relates in particular to the system that the waste gas of smelting furnace generation is processed.
Background technology
At present, smelting iron and steel industry is also focused on implementation environment safeguard measure when developping production, take " energy-conservation, consumption reduction, reduction of discharging, synergy " as aim, and scientific management, Continual Improvement, to reach the unification of social environment benefit and Business Economic Benefit; Existingly for continuous casting smelting furnace burnt gas treatment technology, lack corresponding means, this exists a lot of deficiencies, for example: the dust that melting produces lacks effective dedusting link; Effective not for the sewage disposal producing in processing procedure, need to make rational improvement.
Utility model content
The applicant, for the shortcoming existing in above-mentioned prior art, proposes smelting furnace exhaust treatment system, and it is good to the treatment effect of waste gas, and the sewage of generation can recycle, and reduces the production cost of enterprise.
The technical scheme that the utility model adopts is as follows:
Smelting furnace exhaust treatment system, comprise several dust shields, dust shield is connected by pipeline with some cyclone dust collectors, cyclone dust collectors are connected with air-introduced machine by described pipeline, air-introduced machine communicates with wet cleaner, wet cleaner communicates with chimney, and wet cleaner is connected with precipitation tank, collecting-tank, coagulating sedimentation tower successively, and coagulating sedimentation tower communicates with precipitation tank and sludge-tank;
Further technical scheme is as follows:
Preferably, between described collecting-tank and wet cleaner, water pump is installed;
Preferably, described sludge-tank communicates with filter press by screw pump;
Preferably, described filter press communicates with precipitation tank;
Preferably, described air-introduced machine communicates with a cooling pond.
The beneficial effects of the utility model are as follows: not only can process waste gas, flue dust in waste gas can be changed into convenient processing of mud transports outward simultaneously, also can recycle processing the water source using in waste gas, save enterprise's production cost, and the treatment effect of waste gas be relatively good.
accompanying drawing explanation:
Fig. 1 is movement structure schematic diagram of the present utility model.
the specific embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the utility model comprises several dust shields 1, dust shield 1 is positioned at the top, dust mouth of smelting furnace, the waste gas producing in smelting furnace is played to the effect of collection, dust shield 1 is connected by pipeline with some cyclone dust collectors 2, cyclone dust collectors 2 are eliminated the dust in waste gas in advance, cyclone dust collectors 2 are connected with air-introduced machine 3 by described pipeline, air-introduced machine 3 communicates with wet cleaner 5, preferably, air-introduced machine 3 communicates with a cooling pond 4, cooling pond 4 can provide cooling water in time air-introduced machine 3, reduce the operating temperature of air-introduced machine 3, guarantee that it normally moves, wet cleaner 5 communicates with chimney 6, wet cleaner 5 carries out spraying and dedusting to entering its waste gas entering, pernicious gas in waste gas dissolves in water, as the pernicious gases such as sulfur dioxide form sewage together with dust, the gas that meets environmental protection standard after purification is discharged in atmosphere by chimney 6, wet cleaner 5 successively with precipitation tank 7, collecting-tank 9, coagulating sedimentation tower 10 is connected, the sewage that wet cleaner 5 produces enters in precipitation tank 7 and carries out preformed precipitate, sewage enters in collecting-tank 9 again, after precipitating again, collecting-tank 9 enters again coagulating sedimentation tower 10, preferably, between collecting-tank 9 and wet cleaner 5, water pump 8 is installed, sewage in collecting-tank 9 is carried out to pH value detection, if pH value is 6-9, by water pump 8, the sewage in collecting-tank 9 is directly squeezed into wet cleaner 10 for spraying processing waste gas, coagulating sedimentation tower 10 communicates with precipitation tank 7 and sludge-tank 11, sewage in coagulating sedimentation tower 10 carries out alkaline cleaning, make its pH value reach 6-9, then sewage is entered again to precipitation tank 7, the mud of precipitation enters sludge-tank 11, for the mud in sludge-tank 11 being reclaimed, preferably, sludge-tank 11 communicates with filter press 13 by screw pump 12, by screw pump 12, the mud in sludge-tank 11 is squeezed into filter press 13 and carry out the convenient transportation of cake of press, moisture content in it is fully extruded, preferably, filter press 13 communicates with precipitation tank 7, the sewage that filter press 13 can be produced utilizes again.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
