A tamping coke oven water sealing water recycling system

Abstract

The invention discloses a tamping coke oven water sealing water recycling system, which comprises an upper water tank, a lower water tank and a water pump. Between the water inlet pipe of the sealing system and the upper water pipe of the upper water tank, the water outlet end of the upper water tank is respectively connected with the water seal pipe of the water seal system of the riser pipe and the water seal pipe of the water seal system of the smoke guide pipe, and the water outlet end of the lower water tank is connected with the underground gas The water seal pipe of the valve water seal system is connected, and the water outlet end of the lower water tank is also connected with the water inlet end of the upper water tank through a water pump, and the water inlet end of the lower water tank is connected with the water seal main return pipe; the above water recycling system can not only avoid The water seal water flows back to the quenching tank to cause environmental accidents of waste water leakage and increase its CDQ rate, which can also save a lot of water resources.

Description

technical field [0001] The invention relates to the technical field of coke oven water sealing equipment, in particular to a tamping coke oven water sealing water recycling system. Background technique [0002] see figure 1 , figure 1 It is a schematic diagram of the structure of the water seal system in the prior art. The tamping coke oven is generally designed with a water seal for the rising pipe, a water seal for the smoke guide on the top of the furnace, and a water seal for the underground gas valve. They are all connected to the main water supply pipe 4, and the downpipes of the three water sealing waters are all connected to the main return water pipe 5 below the coke side platform of the coke oven. Flow to the coke quenching pool. [0003] The above-mentioned water sealing system may easily cause the water in the quenching pool to leak out or when the water in the quenching pool is high, water must be used to quench the coke, thereby affecting the CDQ rate. Con...
