Abstract
The utility model discloses a tail gas recovery device of a compound fertilizer. The tail gas recovery device comprises a tail gas outlet of the compound fertilizer, wherein the tail gas outlet is connected with a cyclone dust collector, an exhaust pipe of the cyclone dust collector is connected with an air inlet of a spray washing tank, the cone bottom of the cyclone dust collector is connected with a conveyor, an air outlet of the spray washing tank is connected with an exhausting smoke tube through a heat induced draft fan, an water outlet of the spray washing tank is connected with a sedimentation pond through a pipeline, and the water outlet pipe of the sedimentation pond is connected with a spray nozzle in the spray washing tank through a spray pump. Compared with the prior art, according to the tail gas recovery device of the compound fertilizer, a manner that cyclone dust removal is combined with water spray is adopted, 95% of dust can be removed by the cyclone dust removal, the rest dust is collected by the spray washing tank and the sedimentation pond, and finally effective ingredients in the tail gas are collected; and the gas exhausted by the exhausting smoke tube hardly contain the dust, relevant national discharge standards are met, and the collected dust can be reused, so that the production cost is effectively reduced.
Description
Technical field
The utility model relates to a kind of composite fertilizer device for recovering tail gas, belongs to the compound fertilizer producing equipment technical field.
Background technology
In prior art, in the composite fertilizer drying tail gas with a large amount of powder, if deal with improperly, not only cause waste, more seriously cause environmental pollution, traditional approach dirt pocket gravitational settling can only reach the dust removal efficiency about 80%, still has a large amount of dust to enter atmosphere with tail gas, causes the waste of environmental pollution and composite fertilizer's powder.
Summary of the invention
In order to overcome defects, the utility model provides a kind of composite fertilizer device for recovering tail gas, and this apparatus structure is simple, cost is low, can reclaim the tail gas that produces in composite fertilizer's production process.
To achieve these goals, the technical solution of the utility model is: a kind of composite fertilizer device for recovering tail gas, comprise the tail gas outlet of composite fertilizer, described tail gas outlet is connected with cyclone dust collectors, the blast pipe of cyclone dust collectors is connected with spray washing case air inlet, the cone bottom of cyclone dust collectors is connected with conveyer, the gas outlet of spray washing case is connected with the exhaust chimney through hot air-introduced machine, spray washing case delivery port is connected with settling tank by pipeline, and the outlet pipe of settling tank is connected with shower nozzle in the spray washing case through spray pump.
As to improvement of the present utility model, described exhaust chimney can built-in water spray system or alkaline sprinkler, and spray equipment can pass into clear water or buck, and the residue dust in the tail gas is degraded or the residue sour gas is neutralized again.
Compared with prior art, the mode that retracting device of the present utility model adopts cyclone dust removal to combine with water mist sprinkling, cyclone dust removal can be removed the dust of 95 ℅, remaining part is collected through spray washing case, sedimentation basin, active ingredient in the tail gas is advanced to collect the most at last, and exhaust chimney institute vent gas is with dust hardly, reaches national relevant emission standards, but the dust secondary utilization to collecting effectively reduces production costs.
Description of drawings
Fig. 1 is schematic flow sheet of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Known by Fig. 1, composite fertilizer of the present utility model device for recovering tail gas, comprise the tail gas outlet 1 of composite fertilizer, described tail gas outlet 1 is connected with cyclone dust collectors 2, the blast pipe of cyclone dust collectors 2 is connected with spray washing case 3 air inlets, the cone bottom of cyclone dust collectors 2 is connected with conveyer 4, the gas outlet of spray washing case 4 is connected with exhaust chimney 6 through hot air-introduced machine 5, spray washing case 4 delivery ports 7 are connected with settling tank 8 by pipeline, and the outlet pipe of settling tank 8 is connected with shower nozzle in the spray washing case 4 through spray pump 9.
As to improvement of the present utility model, described exhaust chimney 6 can built-in water spray system or alkaline sprinkler, and spray equipment can pass into clear water or buck, and the residue dust in the tail gas is degraded or the residue sour gas is neutralized again.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model all falls within the protection domain of the present utility model.
