Description

Technical Field

[0001] The utility model relates to the technical field of dry coke quenching waste heat boilers, and more specifically, to a dry coke quenching waste heat boiler device for coal coking. Background Art

[0002] Coking generally refers to the process of carbonization and charring of organic matter; the coking process is a comprehensive process of thermal decomposition and condensation. Coal coking is widely used in the chemical industry, pharmaceutical industry and refractory industry.

[0003] When the existing dry coke quenching waste heat boiler device for coal coking is in use, a filter is set at the air inlet to filter some flue gas particles in the flue gas to prevent the particles from causing wear on the heating surface in the device. Although this method can effectively block the flue gas, the long-term use of the filter will easily lead to the rapid accumulation of flue gas particles on one side thereof, and it needs to be replaced frequently, which greatly increases the labor consumption. In addition, the flue gas particles falling from the filter will fall into the air inlet and are not easy to clean. In addition, the frequent replacement of the filter will make it difficult to detect flue gas leakage in time when it occurs, which poses certain safety hazards. Utility Model Content
