Description
Technical field
The present invention relates to a kind of coal chemical enterprise circulating water system, particularly a kind of coking recirculated water zero discharging system.
Background technology
Contain Dust Capacity in the on-the-spot relatively elsewhere air in coke-oven plant more, 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, the overproof water quality of recirculated water mainly concentrates on the opacity in coke-oven plant's circulating water system, what the recovery unit reaction was the strongest also is that impurity is many in the recirculated water, 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 the coke-oven plant, can't all digest, and is 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
Technical problem solved by the invention has provided a kind of coking recirculated water zero discharging system, this invention has realized the again recycle of the sewer that turbidity of circulating water exceeds standard, realized that zero of sewage effluxes, effectively saved water resources, reduced the waste of resource.
For solving the problems of the technologies described above, a kind of coking recirculated water of the present invention zero discharging system, comprise the coking circulating water pool, the microparticle strainer, the 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 the microparticle strainer, described Circulating water effluent pipeline is connected in the sewer water collecting basin, between described sewer water collecting basin and the microparticle strainer filtration pump is set, be connected by pipeline between described filtration pump and the blowdown water collecting basin, be respectively arranged with between described filtration pump and the microparticle strainer into strainer pipeline and microparticle Filter Back Washing pipeline; The bottom of described sewer water collecting basin and microparticle strainer respectively correspondence is provided with blow-off pipe, and described blow-off pipe all is connected in the grey water system pipeline.
Described two-way pipeline comprises outlet conduit and water return pipeline.
Advancing on strainer pipeline and the microparticle Filter Back Washing pipeline of described connection filtration pump and microparticle strainer is respectively equipped with the pipeline switch valve.
Described pipeline switch valve is the automatic pipeline switch valve.
The invention has the beneficial effects as follows: the present invention efficiently solves recirculated water because turbidity carries out a large amount of blowdowns greatly, causes the situation that new water consumption is too much and large amount of sewage effluxes.Guaranteed the recycled for multiple times of recirculated water, reduced new water consumption, and realized that zero of sewer effluxes, and has saved water resources so that resource is effectively utilized.The cycle water energy of processing through this system reaches production process for the requirement of circulating water quality, has preferably economic benefit and environmental benefit.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present invention;
Among the figure: 1-coking circulating water pool, 2-microparticle strainer, 3-sewer water collecting basin, 4-coking recirculated water user, the two-way pipeline of 5-, 51-outlet conduit, 52-water return pipeline, 6-strainer water return pipeline, 7-Circulating water effluent pipeline, 8-filtration pump, 9-advance strainer pipeline, 10-microparticle Filter Back Washing pipeline, 11-pipeline switch valve, 12-blow-off pipe, 13-grey water system pipeline.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 1, a kind of coking recirculated water of the present invention zero discharging system, comprise coking circulating water pool 1, microparticle strainer 2, sewer water collecting basin 3 and coking recirculated water user 4, one side of described coking circulating water pool 1 arranges two-way pipeline 5, described two-way pipeline 5 comprises outlet conduit 51 and water return pipeline 52, described two-way pipeline 52 is connected in coking recirculated water user 4, and the treated recirculated water that enters in the coking circulating water pool 1 transfers to coking recirculated water user 4 for coking recirculated water user along outlet conduit 51.
The opposite side of described coking circulating water pool 1 arranges strainer water return pipeline 6 and Circulating water effluent pipeline 7, described strainer water return pipeline 6 is connected in microparticle strainer 2, after the sewer that process microparticle strainer 2 filters reaches the service requirements of production technique, again enter the recycle system and recycle.Described Circulating water effluent pipeline 7 is connected in sewer water collecting basin 3, enters sewer in the coking circulating water pool 1 in Circulating water effluent pipeline 7 enters sewer water collecting basin 3 by coking recirculated water user 4.Between described sewer water collecting basin 3 and the microparticle strainer 2 filtration pump 8 is set, the sewer in the sewer water collecting basin 3 enters microparticle strainer 2 through filter pump 8 and carries out particle filtration, and sewer after filtering enters coking circulating water pool 1 and carries out recycle.
