Device and method for regulating tar and ammonia water separation effect

Abstract

The invention relates to a device and a method for regulating tar and ammonia water separation effect, and belongs to the technical field of tar and ammonia water separation equipment for coking production. The technical scheme is that a movable bush (4) is positioned in a tank body (1), a positioning seat (6) is fixed at the top of the tank body (1), an adjusting rod (2) is vertically fixed on the positioning seat (6) through a positioning pin (7), the lower end of the adjusting rod (2) is fixedly connected with the movable bush (4), the bottom of the tank body (1) is connected with a tar inlet pipe (9), the tar inlet pipe (9) extends into the movable bush (4), the side surface of the tank body (1) is connected with a tar outlet pipe (10), and the top of the tank body (1) is connected with a diffusing cylinder (8). With the device and the method, the interface height of tar and ammonia water in the separation tank is adjusted by adjusting the movable bush up and down, so that the separated tar does not contain ammonia water, the separated ammonia water does not contain tar, and the safe and stable production of coke ovens and coal gas purification is guaranteed.

Description

technical field [0001] The invention relates to a device and a method for regulating the separation effect of tar ammonia water, and belongs to the technical field of tar ammonia water separation equipment for coking production. Background technique [0002] The tar ammonia water produced in the coking production process of the coking enterprise enters the tar ammonia water separation tank, the tar and the ammonia water are separated according to the specific gravity difference, the tar sinks to the conical bottom of the separation tank, the ammonia water accumulates in the upper part of the separation tank, and part of the ammonia water passes through the overflow communication pipe After flowing into the jacket layer of the outer chamber of the separation tank, it is sent to the coke oven gas collecting pipe for spraying to reduce the temperature of the coke oven gas. The tar is pressed into the middle tar tank through the pipe which is inserted obliquely into the cone bot...

Problems solved by technology

[0003] The traditional control method for the separation of tar and ammonia water is to manually cut the gate to adjust the separation interface of tar and ammonia in the tar ammonia water separation tank. It is difficult to ensure the separation effect of tar and ammonia water by adjusting the opening of the gate. If the separation interface is too high, the ammonia water will carry tar and block the coke oven. Ammonia sprinkler will affect the cooling of coking gas, which is not conducive to gas purification production; if the separation interface is too low, the ammonia water in tar will exceed the standard, which will affect the deep processing of tar

This control method using the traditional cut-off gate is no longer suitable for the development of coking production. It is necessary to adopt a new control method to improve the separation effect of tar and ammonia water, so that the tar ammonia water produced in the coke oven production process can be completely separated, so that the separated tar without ammonia water can reach Quality index requirements, meet the needs of deep processing of tar, separate ammonia water without tar, ensure that the spraying of ammonia water in coke ovens meets the needs of gas cooling, and ensure the safety and stability of coking production
