[0027] Furthermore, the tower body assembly 22 includes a filter tower body 221, an ash hopper 222 and an air inlet pipe 223. The filter tower body 221 is installed on the top of the fixed frame 211, and the ash hopper 222 is fixedly connected to the bottom end of the filter tower body 221. The air inlet pipe 223 passes through one side of the filter tower body 221. The filter tower body 221 is used to load filter bags 231 to form a filter layer to filter the gas. The ash hopper 222 is used to collect carbon black that falls off the filter bag and transport it to the next processing or packaging link through the discharge pipe 32. The air inlet pipe 223 is used to transport the flue gas containing carbon black into the device, thereby realizing the filtration of the flue gas and the separation of carbon black, and improving the quality and purity of the carbon black.

The filter bag 231 is provided inside the filter tower body 221, and the diversion pipe 232 is provided at the top of the filter bag 231. The filter bag 231 is used to filter the carbon black in the flue gas. It is generally made of high-temperature resistant, wear-resistant, and easy-to-clean materials, such as polytetrafluoroethylene coated filter bags.

[0033] Working principle: First, a pulse ash spraying device for cracking carbon black is moved to the working position. When in use, in the first step, the cracked gas with carbon black is passed into the filter tower body 221 through the air inlet pipe 223 for filtration. In the second step, the gas is filtered through the filter bag 231, and the filtered carbon black is sent out through the discharge pipe 32 under the ash collecting hopper 222 for the next step of producing carbon black. The remaining gas is discharged through the exhaust pipe 31. In the third step, the pressure sensor 252 on the air inlet pipe 223 detects that the intake pressure becomes larger, and the ash spraying component 24 is started to open a part of the electric valve 251 on the diversion pipe 232. In the fourth step, the air is compressed by the air compressor 241, and the compressed air is sent into the pulse tube 242 and passed into the diversion pipe 232 to spray a part of the filter bag 231 with ash. In the fifth step, the electric valve 251 just opened is closed, and the part of the electric valve 251 on the diversion pipe 232 is continued to be opened to continue spraying ash. In this way, the use process of a pulse ash spraying device for cracking carbon black is completed.
