Description

[0002] A tubular cracking furnace refers to a device that performs hydrocarbon cracking reactions in furnace tubes. It is mainly composed of a radiation furnace, a convection furnace, a smoke furnace and a nozzle for supplying heat sources. The fuel oil is sprayed into the furnace through the nozzle and burned. The generated flue gas flows through the convection chamber and is discharged from the chimney. During the use of the equipment, the flue gas will then enter the pipeline, which will increase the temperature inside the pipeline, so heat dissipation treatment is required.

[0003] Chinese patent CN218945028U discloses a cracking furnace tube with uniform heat dissipation. The patent discloses a technical solution for uniform heat dissipation, which solves the problem that when the existing flue gas enters the pipeline, the temperature of one end of the pipeline located at the air inlet is higher than the temperature of the other end at the air outlet. This is because the heat distribution inside the pipeline is uneven, which leads to the problem that the pipeline cannot dissipate heat evenly.

[0004] When the device is in use, impurities are intercepted by the filter plate. The impurities enter the filter holes and block the filter holes. The staff needs to disassemble and clean the filter plate. However, the filter plate is fixedly installed inside the air intake hood, which is not convenient for the staff to disassemble and assemble it. Therefore, a cracking furnace tube with uniform heat dissipation is proposed to solve the above problem. Utility Model Content
