Abstract
Description
Technical Field
[0001] This utility model relates to the field of dry quenching machinery technology in coking plants, and in particular to a water-cooled jacket device for primary dust removal in dry quenching. Background Technology
[0002] Dry quenching in coking plants involves loading red-hot coke from the top of the quenching furnace, where low-temperature inert gas is blown into the furnace by a circulating fan. This gas absorbs the heat and quenches the coke. The cooled coke is then discharged from the bottom of the furnace. High-temperature inert gas exiting the furnace's annular flue flows through the dry quenching boiler for heat exchange, generating steam. The cooled inert gas is then blown back into the furnace by the circulating fan. This closed system allows the inert gas to circulate continuously. Under the influence of the fan, the low-temperature inert gas passes through the red-hot coke, becoming relatively high-temperature inert gas with a high dust content, including large particles of red-hot coke. To remove these larger particles, a gravity dust collector is installed at the furnace's gas outlet. The large dust particles, including red-hot coke and other dust collected by the gravity collector, are discharged through a lower pipe. Due to the high dust temperature, a water-cooled jacket is installed at the inlet of the dust collector pipe to cool the gas.
[0003] Currently used water-cooled jackets have circulating cooling water inside the inner liner and the upper and lower cylinders. The weld between the upper flange plate and the inner wall of the cylinder is in a high-temperature environment, and the weld often cracks and leaks water, affecting the normal operation of the dust removal process. Generally, production needs to be stopped for maintenance every three or four months, and the water-cooled jacket tube needs to be replaced. This usually takes 24 hours, which seriously affects the normal production of dry quenching coke. Utility Model Content
