Problems solved by technology

However, the effect of using sewage to reduce the turbidity of circulating water is slow, and a large amount of sewage needs to be concentrated. While increasing the consumption of new water, centralized sewage will also cause excess water in the coking plant for a short time, which cannot be fully digested, which is very uneconomical.

Abstract

Provided is a zero outward discharge of coking circulating water. The system comprises a coking circulating pool, a microparticle filter, a discharge water collecting pool, a reclaimed water system pipeline and a coking circulating water user. Bidirectional pipelines arranged at one side of the coking circulating pool are connected with the coking circulating water user. A filter backwater pipeline and a circulating water discharge pipeline are arranged at the other side of the coking circulating pool. The filter backwater pipeline is connected with the microparticle filter. The circulating water discharge pipeline is connected with the discharge water collecting pool. A filter pump is arranged between the discharge water collecting pool and the microparticle filter. The filter pump and the discharge water collecting pool are connected through a pipeline. A filter pipeline and a microparticle filter backwash pipeline are arranged between the filter pump and the microparticle filter. Discharged pipelines are arranged at the bottoms of the discharge water collecting pool and the microparticle filter respectively. The discharged pipelines are connected with the reclaimed water system pipeline. The system realizes repeated circular utilization of circulating water, reduces consumption of new water, realizes zero outward discharge of discharge water, and saves water resource.

Description

technical field [0001] The invention relates to a coking enterprise circulating water system, in particular to a coking circulating water zero discharge system. Background technique [0002] Compared with other places, the coking plant site contains more dust in the air, and the dust entering the circulating water system at the cooling water rack of the coking plant circulating water system will be more than other places, which causes the water quality of the circulating water to exceed the standard and circulate in the coking plant. The excessive water quality of the circulating water in the water system is mainly concentrated on the turbidity, and the most intense reaction of the recovery unit is that there are many impurities in the circulating water, which block the heat exchanger. However, the effect of using sewage to reduce the turbidity of circulating water is slow, and a large amount of sewage needs to be concentrated. While increasing the consumption of new water, ...
