いた。 In the pre-chamber formed at the top of the cooling tower, a gas with components equivalent to coke oven gas containing a large amount of CH, H2 , etc. is stored, and this gas has a high calorific value and is heated to approximately 1000℃. It has a high temperature. For this reason, when the furnace lid is opened to add coke, it comes into contact with the atmosphere around the furnace mouth and causes combustion or explosion, which poses a safety problem for workers and can have a negative impact on peripheral equipment due to fire or explosion. They had various problems, such as noise caused by explosions and visual problems caused by fire.

There is. but,
According to this method, a large amount of high-temperature, high-calorie gas is released into the atmosphere, which poses thermoeconomic problems, and dust-containing gas is released directly into the atmosphere, causing dust pollution. Therefore, there have been problems such as the need for a large-sized combustion device to combust the diffused gas.

整方法、に係るものである。 The present invention was made in order to solve the problems of the conventional methods. A part of the gas in the pre-chamber is taken out to the outside, the components are analyzed, and the components are determined based on the proportion of combustible components in the gas. By directly introducing regulating gas into the pre-chamber from the outside to adjust the gas components in the pre-chamber, it is possible to prevent explosions and combustion of the gas in the pre-chamber when the furnace lid is opened, and to make the thermal energy of the gas in the pre-chamber more effective. This invention relates to a method for adjusting gas components in a pre-chamber in a coke dry extinguishing system designed to prevent pollution problems caused by use and dissipation.

せるようにした制御装置１９，２０を設ける。 In the cooling tower 1 of the coke dry extinguishing equipment having the above configuration, as shown in FIG.
A component adjustment gas pipe 15 introduced through 4 is connected. Further, the component adjusting gas pipe 15 may be connected to the upper part of the pre-chamber 2 at a position where the red hot coke 16 is not deposited. Further, a component analyzer 18 is provided which extracts the gas in the pre-chamber 2 through a sampling tube 17 and analyzes its components. Control devices 19 and 20 are provided to open the flow rate regulating valve 14 when a certain value is reached.

焼のために爆発が生じる。 The temperature of the gas in the pre-chamber 2 mentioned above is approximately 1000℃.
The main components are CO and H2 . Therefore, in such a high temperature atmosphere, CO and H 2 become O 2
If there is, it will burn immediately. Moreover, the upper part of the pre-chamber 2 is filled with light components such as CO and H2 , so when the furnace lid is opened, it reacts with O2 in the air and burns, causing rapid combustion especially when the concentration of CO and H2 is high. An explosion occurs because of this.

and introduce a component adjustment gas so that each or the total amount of CO and H2 in the gas in the pre-chamber 2 is maintained at a certain set value or within a range below a certain set value. control. Or
When each or the total amount of CO and H 2 in the gas in the pre-chamber 2 exceeds a certain set amount, the flow rate regulating valve 14 is opened. At this time, when air is used as the composition adjustment gas, CO and H 2 are burned and diluted, and when N 2 gas is used, the composition is simply diluted.
