Description

Technical Field

[0001] The utility model relates to the technical field of recycling of circulating water in the water seal tank of coke dry quenching, and particularly relates to a device for recycling circulating water of the coke dry quenching body. Background Art

[0002] The coke dry quenching system consists of a coke conveying and cooling system, an inert gas circulation system, a steam-water system, a dust removal system and a circulating water system.

[0003] The coke conveying and cooling system of coke dry quenching mainly consists of a red coke conveying system, a red coke charging system, a coke dry quenching furnace system and a cold coke discharging system. This system consists of equipment such as a motor car, a coke pot, a coke pot trolley, an APS alignment device, a hoist, a charging device, a coke dry quenching furnace, a cold coke discharging device, a coke conveying belt, etc.

[0004] The circulating water system of coke dry quenching consists of a circulating water supply pump, a cooling tower, a circulating water pipeline, a filter and a water quality stabilization device. The circulating water is pressurized by a pump and sent to users for use. The return water residual pressure enters the cooling tower, is cooled and then flows into the suction well by itself, and after being subjected to water quality stabilization treatment, it is lifted by a pump and sent to users for recycling.

[0005] The circulating water system of coke dry quenching includes a circulating water system for coke dry quenching power generation and a circulating water system for the coke dry quenching body. The circulating water system for coke dry quenching power generation mainly supplies cooling water for the steam condenser of the coke dry quenching steam turbine generator. The circulating water system for the coke dry quenching body mainly supplies water for places such as the top of the coke dry quenching furnace, the top discharge, the water seal of the emergency discharge of the primary dust removal, the water-cooled sleeve of the primary dust removal, the dust removal fan and the boiler cooling system.

[0006] A water seal tank is provided at the top of the coke dry quenching furnace to solve the top sealing and temperature reduction. The water seal tank cooperates with the furnace cover or the water seal cover to prevent dust from escaping and air from leaking in. Stainless steel compressed air pipes and water pipes are arranged in the water seal tank. When compressed air is passed through, bubbles are generated in the water seal tank. Through rotation and bubbling, the sediment falling into the water seal tank from the coke charging port is discharged along the upper overflow port. There is a drain port at the bottom of the water seal tank and a full-flow drain port near the upper part. For the coke dry quenching body, there are also top discharges and emergency discharges respectively located at the charging platform of the coke dry quenching furnace and the top of the primary dust collector. Water seal tanks are respectively configured at the tops of the two discharge ports. There is a drain port at the bottom of the water seal tank and a full-flow drain port at the upper part. The circulating cooling water discharged from the three water seal tanks through draining and full-flow is discharged to the ground sewage well for treatment and then discharged. At the same time, for the coke dry quenching body, there is also a water-cooled sleeve for the primary dust removal that uses circulating cooling water to exchange heat and cool the hot coke powder in the system and then discharges it to the ground water well for treatment and then discharged.

[0007] In the prior art, the circulating cooling water after heat exchange in the coke dry quenching system is directly discharged externally, wasting circulating water resources. Summary of the Utility Model
