Description
Technical field
The utility model relates to a kind of coal chemical enterprise circulating water system, particularly a kind of coking recirculated water zero discharging system.
Background technology
More containing Dust Capacity in the on-the-spot elsewhere air relatively in coke-oven plant, the dust that enters circulating water system at circulating water system cooling rack place, coke-oven plant will be more than elsewhere, this has just caused the overproof water quality of recirculated water, in coke-oven plant's circulating water system, the overproof water quality of recirculated water mainly concentrates in opacity, what recovery unit reaction was the strongest is also that in recirculated water, impurity is many, stops up interchanger.And utilize the way effect of blowdown reduction turbidity of circulating water slower, and need to concentrate a large amount of blowdowns, when causing new water consumption to increase, concentrated blowdown also can cause water short period of time surplus in coke-oven plant, cannot all digest, very uneconomical.In order to reduce unnecessary water resource waste, guarantee the recycled for multiple times of recirculated water, and special design this coking recirculated water zero discharging system.
Summary of the invention
The technical problem that the utility model solves has been to provide a kind of coking recirculated water zero discharging system, this utility model has realized the recycle again of the sewer that turbidity of circulating water exceeds standard, the zero outer row who has realized sewage, has effectively saved water resources, has reduced the waste of resource.
For solving the problems of the technologies described above, a kind of coking recirculated water of the utility model zero discharging system, comprise coking circulating water pool, microparticle strainer, sewer water collecting basin, grey water system pipeline and coking recirculated water user, one side of described coking circulating water pool arranges two-way pipeline, described two-way pipeline is connected in coking recirculated water user, the opposite side of described coking circulating water pool arranges strainer water return pipeline and Circulating water effluent pipeline, described strainer water return pipeline is connected in microparticle strainer, described Circulating water effluent pipeline is connected in sewer water collecting basin, between described sewer water collecting basin and microparticle strainer, filtration pump is set, between described filtration pump and blowdown water collecting basin, by pipeline, be connected, between described filtration pump and microparticle strainer, be respectively arranged with into strainer pipeline and microparticle Filter Back Washing pipeline, described sewer water collecting basin and the bottom of microparticle strainer respectively correspondence are provided with blow-off pipe, and described blow-off pipe is all connected in grey water system pipeline.
Described two-way pipeline comprises outlet conduit and water return pipeline.
Entering on strainer pipeline and microparticle Filter Back Washing pipeline of described connection filtration pump and microparticle strainer is respectively equipped with pipeline switch valve.
Described pipeline switch valve is automatic pipeline switch valve.
The beneficial effects of the utility model are: the utility model efficiently solves recirculated water because turbidity carries out greatly a large amount of blowdowns, cause the situation that new water consumption is too much and large amount of sewage is arranged outward.Guaranteed the recycled for multiple times of recirculated water, reduced new water consumption, and realized zero outer row of sewer, saved water resources resource is effectively utilized.The cycle water energy of processing through this system reaches production process for the requirement of circulating water quality, has good economic benefit and environmental benefit.
