Stamp-charging coke oven water seal water recycling system

Abstract

The invention discloses a stamp-charging coke oven water seal water recycling system which comprises an upper water tank, a lower water tank and a water pump. The upper water tank is arranged at the top of a tamping coke oven; the lower water tank is arranged among a water seal main water return pipe, an underground gas valve water seal system water inlet pipe and the upper water pipe of the upperwater tank; the water outlet end of the upper water tank is communicated with the water seal pipe of an ascending pipe water seal system and the water seal pipe of a smoke guide pipe water seal system, the water outlet end of the lower water tank is communicated with the water seal pipe of the underground gas valve water seal system and further connected with the water inlet end of the upper water tank through the water pump, and the water inlet end of the lower water tank is communicated with the water seal main water return pipe. With application of the water recycling system, the environmental protection accident of wastewater leakage caused by the fact that the water seal flows back to the coke quenching pool can be avoided, the coke dry quenching rate is increased, and a large amountof water resources can be saved.

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.
