Description of the Related Art An apparatus for a C gas refining process in a coke factory has an open portion, and low boiling point components such as benzene, toluene, and xylene in tar are volatilized from the opened portion. These hydrocarbons give off an odor and are one of the causative substances that cause air pollution.

ルギーを必要とする。In order to eliminate the above problems, it is necessary to prevent the vaporized hydrocarbons from leaking to the surroundings. Then, in order to prevent the leakage of hydrocarbons, it is necessary to suck and exhaust the atmosphere of the opening and its surroundings, but the sucked exhaust must be treated to remove the hydrocarbons when releasing the atmosphere. .
Further, since this exhaust gas contains only a trace amount of hydrocarbons and cannot self-combust, a special device must be installed and treated. As a special device, there is, for example, a device described in Japanese Patent Application Laid-Open No. 1-21211, which burns hydrocarbons in exhaust gas in the presence of a catalyst. Furthermore, when the hydrocarbon in the exhaust gas is burned by the above-mentioned catalytic oxidation method, the exhaust gas must be heated to several hundred degrees, and energy for that purpose is required.

た排気を混入すれば、排気中の炭化水素は燃焼する。In dry coke fire extinguishing, red hot coke is charged into a cooling tower, and cooling gas is introduced into the cooling tower to cool the red hot coke. This cooling gas is circulated and used while being recovered by the waste heat boiler. The temperature of the cooling gas discharged from the cooling tower is a high temperature of about 800 ° C. Therefore, if the exhaust gas sucked from the open part of the apparatus in the C gas refining step is mixed with this cooling gas, the hydrocarbons in the exhaust gas will burn.
