Description

Coking strong brine is used for towards processing system of sediment

Technical Field

The utility model relates to the technical field of coke oven production, in particular to a treatment system for washing slag by using coking strong brine.

Background

The coking can produce the waste water of strong brine in the production, if direct emission can cause the pollution to the environment, the feature of environmental protection is relatively poor, is unfavorable for long-term production and development, and the device that sets up waste water treatment specially then has increased input cost and operation maintenance cost, and economic nature is relatively poor.

Disclosure of Invention

The utility model aims to solve the problem of coking strong brine treatment, provides a treatment system for coking strong brine used for slag flushing, and is environment-friendly and economical.

The specific scheme of the utility model is as follows: the utility model provides a coking strong brine is used for towards processing system of sediment, includes the cooling tower, and the cooling tower upper end is equipped with strong brine import and towards sediment water backward flow mouth, and the cooling tower bottom is equipped with the outlet, and the outlet outer end is through towards sediment water piping connection granulation jar, and granulation jar upper end is equipped with the slag-iron entry, and the lower extreme is equipped with the delivery port, and the delivery port outer end is through the pipe connection end filter tank, and end filter tank is equipped with a wet return, and the wet return is connected to towards sediment water backward flow mouth is equipped with the backwash pump on the wet return.

A sampling pipe of a bypass is arranged on the slag flushing water pipe, and a valve is arranged on the sampling pipe.

The bottom filter chamber comprises a filter chamber body, wherein a filter material A is arranged at the bottom in the filter chamber body, a filter material B is arranged above the filter material A and is used for filtering larger slag iron in the slag washing water, and the filter material A is used for filtering thinner slag in the slag washing water.

A layer of anti-collision beam is arranged between a filter material A and a filter material B; the anti-collision beam is used for protecting the filter material A.

A reverse flushing pipeline is embedded in the filter material A.

The working principle of the utility model is as follows: sending strong brine discharged by coking into a cooling tower to be mixed with original slag flushing water, then conveying the strong brine into a granulation tank, enabling blast furnace slag flushing to enter the granulation tank and then flow into a bottom filter together with the slag flushing water for filtering, and finally pumping the filtered slag flushing water into the cooling tower through a reflux pump for reciprocating circulation; the slag flushing water is periodically extracted through the sampling tube to be detected, the corrosivity of the slag flushing water to the equipment pipeline is judged, and the strong brine quantity of the cooling tower is fed back and controlled according to the detection result so as to ensure the long-term stable operation of the equipment pipeline.

The utility model has the following beneficial effects: 1. the coking strong brine is input into the slag flushing water, and the slag iron of the blast furnace is treated along with the slag flushing water, so that the strong brine is consumed on the premise of not increasing the cost, and the coking strong brine is environment-friendly and has certain economical efficiency; 2. through the periodic sampling, the mixed slag flushing water is detected, the corrosion of slag treatment pipelines and equipment is reduced, the equipment operates efficiently and economically, and the smooth production of a slag treatment system is guaranteed.
