Description

Wet electrical dust precipitator sewage self-circulation processing device
Affiliated technical field:
The utility model relates to a kind of effluent cycle treatment facility, particularly wet electrical dust precipitator sewage self-circulation processing device.
Background technology:
Wet electrical dust precipitator has been widely used in steel production enterprise, and especially in the production technology of coal gas of converter system, the enterprise that is applied as of wet electrical dust precipitator reduces production costs, and improves the quality of products and has created condition.But the processing of wet electrical dust precipitator sewage is a difficult problem all the time.Common way is the turbid circulating water system that the sewage of electric cleaner discharging is drained into steel-making.Because wet electrical dust precipitator belongs to smart cleaner, the diameter of the particle of contained dust is very little in the sewage, and the density of these dust granules is also very little, form with suspension in water exists, these sewage are delivered to go to handle in the steel-making turbid circulating water system exist following shortcoming: one, poor processing effect, expense height.Statistics shows, when the quantity of wastewater effluent of wet electrical dust precipitator be 128 tons/constantly, the turbid circulating water system expenses that consume chemicals in every year more than 1,000,000 yuan more, and suspension content is still very high in the water after treatment.The suspension content height is a kind of soft injury to STEELMAKING PRODUCTION in the turbid circulating water, it can not make production system stop production immediately, but the suspension in the turbid circulating water is layer by layer on the inwall attached to I and II venturi tube gas washer, the equipment flow area of causing reduces, be reduced to the snaking of to a certain degree have to being forced to stop production, and the labour intensity of the inner snaking of artificial access arrangement is big, degree of danger is high.The more important thing is that because wet electrical dust precipitator can not be done the water source with turbid circulating water, efflux naturally again after treatment so be discharged into the sewage of turbid circulating water system, this multiple loss must cause the rising of production cost.Outer draining has caused environmental pollution simultaneously, that is to say poor processing effect, the cost height of existing sewage treatment process, and influence is produced and contaminated environment.
The utility model content:
The utility model purpose provides a kind of wet electrical dust precipitator sewage self-circulation processing device, and wet electrical dust precipitator sewage by handling, is made it automatic circulation, and energy-conserving and environment-protective solve the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
Wet electrical dust precipitator sewage self-circulation processing device is formed and to be comprised wet electrical dust precipitator, waste water container, sewage pump, chemical scrubbing container, filters container, fresh water container, clarified water pump soon, the bottom of wet electrical dust precipitator is connected with waste water container by pipeline, waste water container is connected with chemical scrubbing container by sewage pump, pipeline, chemistry scrubbing container is connected with fast filter container by pipeline, fast filter container is connected with fresh water container by pipeline, and fresh water container is connected with the wet electrical dust precipitator top by clarified water pump, pipeline.
Between fast filter container and fresh water container, be provided with backwashing pump, be connected between fast filter container and the fresh water container by pipeline, and be connected with waste water container by pipeline.
Be provided with dosing pump and molten medicine container on chemical scrubbing container side, chemical scrubbing container is connected with dosing pump by pipeline, and dosing pump connects molten medicine container.
Be provided with water filter between clarified water pump and the wet electrical dust precipitator top, water filter is connected with the wet electrical dust precipitator top with feed pump by pipeline.
Adopt the utility model, the sewage that wet electrical dust precipitator is discharged is compiled in waste water container, with sewage pump it is delivered to chemical scrubbing container then, sewage reacts preliminary scrubbing, oil removing with relevant chemical agent in chemical scrubbing container, dirt is deposited in the bottom of chemical scrubbing container in the water, can concentrate it is delivered to iron-smelter to do raw material.Flow to fast filter container through the water that chemical scrubbing container is handled and further purify (suspension has only 5-30mg/L in the water at this moment), inject fresh water container afterwards, clarified water pump is delivered to wet electrical dust precipitator to clear water in the fresh water container again and is sprayed, and the sewage that spray forms injects waste water container, so circulation.
After fast filter container moves a period of time, can the clear water in the fresh water container be sent into fast worry container by backwashing pump and carry out backwash, the sewage that backwash produces also injects waste water container, has so just formed the self-loopa treatment system of a complete closed.
The utlity model has following characteristics: 1. processing cost is low, and clean water quality is stable.Be multiplied with comparing in the past continous-stable running time of 2. relevant watering equipment.3. eliminated pollution to environment.The utlity model has social benefit and economic benefit widely, water-saving and environmental protection.
