Diffusion system and diffusion method for coke oven raw gas emergency ignition

Abstract

The invention discloses a diffusion system and a diffusion method for coke oven raw gas emergency ignition. The diffusion system is provided with a coal tower, at least two diffusion pipes, a solenoidvalve, a pressure gage, a button and an UPS (Uninterrupted Power Supply), wherein the coal tower is provided with a gas collection pipe; the diffusion pipes are communicated with the gas collection pipe; the solenoid valve is arranged on the connection part of the diffusion pipes and the gas collection pipe; the pressure gage is arranged on the gas collection pipe and is capable of detecting pressure in the gas collection pipe; the button is connected with the solenoid valve through a circuit and controls the solenoid valve to be switched on and off; the UPS (Uninterrupted Power Supply) is connected with the solenoid valve through a circuit to provide uninterrupted power for the diffusion system, a situation that operation can not be carried out due to outage is avoided, the raw gas of the gas collection pie can be timely and quickly diffused, and a normal working condition is recovered in time according to a working condition so as to stabilize the pressure of the gas collection pipeand lower potential safety hazards.

Description

technical field [0001] The invention belongs to the technical field of coke ovens, and in particular relates to an emergency ignition and release system for coke oven waste gas and a release method thereof. Background technique [0002] The traditional coke oven gas collection pipe automatic release is that the pressure of the gas collection pipe exceeds a certain range and reaches a certain period of time before automatically starting the release ignition function, which can meet the conditions after the suction drops slowly, but when encountering a sudden power failure or trip of the fan, the coke oven often It was too late to activate the release ignition function, resulting in the burnout of electrical, instrumentation and other equipment and facilities in the riser system in a short period of time. Once the coke oven raw gas system has no suction, the raw gas diffuses into the coke oven area. In the traditional manual release and ignition, at least two people are often ...

AI Technical Summary

Problems solved by technology

On the one hand, it is not easy for one person to observe the amount of raw gas released, which may easily cause serious unorganized release on site; on the other hand, the release pipe is not closed tightly after the release, and a person needs to go up and manually close it tightly

Due to production costs and daily operation needs, there is only one person on the exhaust pipe in daily operation, and it is difficult to switch the exhaust pipe in time

At the same time, the current collector release ignition device is not sensitive enough, and it needs multiple ignitions to succeed

For evacuation, only one evacuation pipe can be opened at a time, and multiple evacuation pipes cannot be opened at one time. When an emergency problem is encountered, it cannot be dealt with promptly and quickly, resulting in serious safety hazards in the operation of the air collecting pipe system

[0003] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: the coke oven release technology in the industry mainly deals with the slow release process, and cannot respond smoothly and quickly to situations such as sudden complete power failure and tripping of the fan system
