である。6. Coke oven gas generated in a coke oven during coke production is collected in a dry main through a riser pipe installed at the top of the coke oven, cooled by ammonium water spraying, and separated into gas and liquid. Each tar component is effective (
-Used. However, this coke oven gas has a huge amount of sensible heat, reaching nearly 1000℃ immediately after its generation (2).Despite this, coke oven gas contains a large amount of tar. Therefore, it is difficult to recover and effectively utilize this coke oven gas sensible heat, and the current situation is that most of it is discarded without being used.

かった。By the way, as an attempt to recover this coke oven gas sensible heat, a heat exchanger is installed in the riser pipe of the coke oven, and the coke oven gas is transferred between the heat medium circulating in the heat exchanger and the coke oven gas. It has been proposed to exchange heat. However, even in this method C2, when attempting to recover a large amount of coke oven gas sensible heat by increasing the heat transfer area of the heat exchanger, the heat transfer surface of the heat exchanger (the nital content is large 4 + 2 fixed However, there are problems such as causing failures and significantly reducing the heat exchange efficiency of the heat exchanger.

きない。Therefore, the inventors investigated the cause of this problem and found that not only did nital adhere to the heat transfer surface of the heat exchanger, but also that the lid at the top of the riser pipe was opened before the coke was taken out of the pot. When the coke oven gas remaining in the coke oven is combusted, or when the generated coke is partially combusted when the coke is taken out of the coke, high-temperature hot air rises through the riser pipe.
The tar adhering to the heat transfer surface of the heat exchanger is exposed to this hot air and carbonizes, so-called coking, which adheres to the heat transfer surface of the heat exchanger, and this gradually grows and causes malfunctions and heat. It was found that this causes a decrease in exchange efficiency.Therefore, in order to prevent this coking, it is necessary to recover the coke oven gas sensible heat in the riser pipe at a high temperature range of at least about 500℃ or higher. Therefore, the sensible heat of the coke oven gas cannot be sufficiently recovered by recovering heat only from the riser pipe section.

-By recovering the sensible heat of the coke oven gas in this heat recovery section, even if tar adheres to the heat transfer surface of the heat exchanger, it will not be exposed to the hot air C2 rising in the riser pipe, so the tar can be coked. The present invention was completed by discovering that it could be collected in dry main without any problems.

ない。As described above, according to the coke oven gas sensible heat recovery method and device C2 according to the present invention C2, a heat exchanger is disposed in the connecting pipe connecting the riser pipe section and the dry main of the coke oven. The heat transfer surface of the heat exchanger exchanges heat between the heat medium circulating in the heat exchanger and the high-temperature coke oven gas generated during coal carbonization. In addition to recovering heat, the tar in the coke oven gas that condensed on the heat transfer surface of the heat exchanger was recovered in the dry main, so the lid at the top of the riser pipe was opened before the generated coke was discharged from the pot. When the coke oven gas remaining in the coke oven is burned, or when the generated coke is taken out of the coke (part of the Ninoke is burned and the inside of the riser pipe is exposed to high-temperature hot air, heat exchange is not possible). The tar attached to the heat exchanger is not exposed to this hot air, and causes caulking and hardening on the heat transfer surface. There is no such thing as deteriorating the quality.

らしても極めて実用的価値の高いものである。Therefore, according to the coke oven gas sensible heat recovery method and recovery device (2) according to the present invention, the coke oven gas sensible heat is recovered between the riser pipe section and the dry main of the coke oven, and is condensed to generate heat. The tar deposited on exchanger C2 can be collected in the dry main without coking, so the temperature of the coke oven gas can be reduced to about 80 to 100 degrees Celsius by flushing with ammonium water. It is possible to recover gas sensible heat, and it is possible to recover heat about twice as much as the conventional method of recovering coke oven gas sensible heat in the riser pipe section. Use of recovered coke oven gas sensible heat (even if there are two, it can be used for multiple purposes such as preheating coking coal, power generation, heat source for auxiliary equipment, district heating, etc.), and has extremely practical value from an energy saving perspective. It's expensive.
