Problems solved by technology

[0003] After stabilization, close the valves. More factories often turn off the permanent lights because of the waste. This is because the valves generally leak internally after use. In addition, the instrument air pressure is about 0.7MPa, and the coke oven gas pressure is 8-11KPa. , the air will enter the coke oven gas system. If the oxygen content exceeds 0.5%, it may cause the fine desulfurization to overheat, burn out the catalyst, and may cause an explosion if the deflagration ratio is reached.

Abstract

The invention relates to a torch ignition device, and in particular discloses a torch deflagration ignition safety system. The torch deflagration ignition safety system includes instrument air pipes and coke oven gas pipes respectively connected to the mixer through pipes, and is characterized in that valve A, filter A, valve B, valve A, filter A, valve B, Pressure regulating valve A and one-way valve A, the coke oven gas pipe connected to the mixer are provided with valve E, filter B, valve D, valve C, pressure regulating valve B and one-way valve B, valve A and valve The pipeline between B is communicated with a short connection pipe, and a valve F is installed on the short connection pipe. The invention is simple in structure, easy to use, reasonable in design, flexible in application, can accurately control the gas composition of the mixer, and effectively prevents instrument air and coke oven gas from crossing each other, ensures safe use, and is suitable for wide popularization and application.

Description

(1) Technical field [0001] The invention relates to a torch ignition device, in particular to a torch deflagration ignition safety system. (2) Background technology [0002] The torch ignition generally uses a high-voltage spark plug to ignite. If it fails to ignite, there will be a deflagration ignition. The principle is that the instrument air enters the mixer through the valve, filter, valve, pressure regulating valve, and check valve, and the fuel gas (coke oven gas) It also enters the mixer through valves, filters, flame arresters, valves, pressure regulating valves, and one-way valves. When the pressure of the two gases is similar and the ratio is within the deflagration range, ignite in the mixing chamber, and the mixer will explode instantly. Go to the top of the torch, light the ever-burning lamp, and then the ever-burning lamp will lead the torch. [0003] After stabilization, close the valves. More factories often turn off the permanent lights because of the wast...
