[0002] The gas industry is an important auxiliary industry for the steel industry. my country's energy characteristics are rich in coal, poor in oil and little gas. Gas is a combustible gas converted from coal through a gas generator. Compared with the combustion of coal, the combustion of gas is cleaner and more efficient. Therefore, gas as a clean energy is receiving more and more attention.

[0003] During the low-temperature dry distillation of coal, the temperature of the raw gas coming out of the dry distillation furnace is about 600°C, so it needs to be cooled and then collected. At present, the humidification and cooling method or the traditional ammonia cooling process is used for cooling. However, the humidification and cooling method will bring a lot of moisture into the raw gas during the cooling process. The moisture in the gas is not conducive to direct supply to users.

[0026] When the closed cooling water tower for coal gas is in use, the staff discharges the coal gas to be cooled into the interior of the closed cooling water tower 1 through the coal gas input pipe 2, the coal gas enters the interior of the water cooling pipe 5 on the right side and gradually flows downward into the bottom of the closed cooling water tower 1, the coal gas enters the interior of the water cooling pipe 5 on the left side again and gradually moves upward into the top of the closed cooling water tower 1, and is finally discharged from the coal gas discharge pipe 3. At this time, the water cooling pump 12 draws water from the inside of the water storage tank 10 through the pumping pipe 13 and inputs it into the interior of the cooling water input pipe 8 through the drain pipe 14. The cooling water finally enters the middle position of the two discs 4 and gradually flows upward to cool the coal gas inside the water cooling pipe 5. The cooling water finally flows into the interior of the water storage tank 10 through the cooling water discharge pipe 9 and the connecting hose 15 to complete the circulation of the cooling water.
