A water seal tank and dry quenching furnace

Abstract

The embodiment of the invention provides a water seal tank and a dry quenching furnace. The water seal tank comprises a first tank body, isolation cabins, a second tank body and isolation plates, wherein the isolation cabins are arranged on the outer side of the first tank body; a plurality of overflow ports are formed in the upper portions of the outer sides of the isolation bins, and a pluralityof through holes are formed in the bottoms of the isolation bins; a cooling groove is formed between the second tank body and the first tank body; the isolation plates are arranged in cooling grooves, and the isolation plates are connected with the bottoms of the isolation cabins; the isolation plates divide the cooling grooves into first cooling cabins and second cooling cabins; and the second cooling cabins are used for cooling the bottom surface of the water sealing tank, and the first cooling cabins are used for overflowing coke powder in a falling-in groove.

Description

technical field [0001] The invention belongs to the technical field of dry quenching and coking, and in particular relates to a water-sealed tank and a dry quenching furnace. Background technique [0002] CDQ device is based on inert gas N 2 It is an energy-saving and environment-friendly device that cools and extinguishes red coke as a heat exchange medium and heats a boiler to generate electricity. [0003] In the actual production process, after the red coke is installed in the CDQ furnace, the water seal tank is used to cooperate with the furnace cover or the movable sealing cover to prevent dust from overflowing and air from leaking in. [0004] In the process of coke canned red coke, a large amount of coke powder will fall into the water-sealed tank, and the fallen coke powder needs to be cleaned every 24 hours. Buckle edge, the cleaning space is very narrow, it is difficult to clean the coke powder, and only a small amount of coke powder on the outside of the buckle...

AI Technical Summary

Problems solved by technology

[0004] In the process of coke canned red coke, a large amount of coke powder will fall into the water-sealed tank, and the fallen coke powder needs to be cleaned every 24 hours. Buckle edge, the cleaning space is very narrow, it is difficult to clean the coke powder, and only a small amount of coke powder on the outside of the buckle edge can be cleaned. Over time, the coke powder deposits and scales on the bottom and inner side of the water seal tank, and the coke powder scales after the tank The body weld seam is covered by the scale surface, and the thicker the knot, and then baked at a high temperature in the furnace, the coke powder and scale body in the tank becomes harder and denser, occupying the cooling space, and the weld seam loses its cooling effect. Effect, affected by the thermal expansion stress of the material, the weld seam of the tank body is cracked, which affects the normal production operation and increases the high maintenance cost
