Description

Technical Field

[0001] The utility model relates to the technical field of dry quenching in the coking industry, in particular to a bearing protection device. Background Art

[0002] Coke dry quenching (CDQ), as opposed to wet quenching, refers to a quenching method that uses inert gas to cool red coke. During the CDQ process, red coke is loaded from the top of the CDQ furnace. Low-temperature inert gas is blown into the red coke layer in the CDQ furnace's cooling section by a circulating fan, absorbing the sensible heat of the red coke. The cooled coke is then discharged from the CDQ furnace's bottom. The high-temperature inert gas from the CDQ furnace's annular flue flows through the CDQ boiler for heat exchange, generating steam. The cooled inert gas is then blown back into the CDQ furnace by the circulating fan, circulating within the closed system.

[0003] The CDQ system mainly consists of a coke cooling system, a circulating gas system, a boiler steam-water system and a dust removal system.

[0004] The CDQ boiler is a pressurized and heated equipment that uses the high-temperature circulating gas that has absorbed the sensible heat of the red coke to exchange heat with desalted and deoxygenated pure water to generate steam with rated parameters (temperature and pressure) and quality, and then delivers it to heat users.

[0005] The primary function of a CDQ boiler feedwater pump is to extract treated feedwater from the deaerator storage tank and, through the pump's pressurized action, deliver it to the boiler. This ensures a stable and sufficient water supply to the boiler, thereby maintaining the internal water balance. Furthermore, the boiler feedwater pump must operate continuously to ensure consistent feedwater flow, which has a direct impact on boiler safety and efficiency.

[0006] During normal CDQ operation, the boiler feedwater pump draws treated feedwater from the deaerator's water storage tank and delivers it to the boiler through pressurized pressure. This ensures a stable and sufficient water supply to the boiler, maintaining the internal water balance. Furthermore, the boiler feedwater pump must operate continuously to ensure the continuity of the boiler feedwater supply, which has a direct impact on the boiler's safe production and efficiency. However, since the bearings of the boiler feedwater pump rotate continuously at high speed during operation, this poses a safety hazard to routine workers inspecting the pump and to outsiders accidentally touching the pump. To ensure the safety of workers inspecting the boiler feedwater pump and other pumps, as well as outsiders, protective devices must be installed on the rotating bearings of each body.
