The filter screen cartridge 205 is made of activated carbon material.

Then, an air outlet pipe 206 is installed on one side of the feed pipe 203 and on the outer wall of the filter barrel 202. One end of the air outlet pipe 206 passes through the filter barrel 202 and extends to the interior of the filter barrel 202 and is connected to an air outlet cylinder 207. A ventilation groove is provided on the outer wall of the top of the air outlet cylinder 207. Under the action of the air outlet cylinder 207 located above the filter screen cartridge 205, it is located in the filter barrel 202. The gas in the upper part gathers above the filter barrel 202, and the gas enters the inner cavity of the gas outlet cylinder 207 through the ventilation groove. Then, when the filter screen cartridge 205 needs to be replaced after processing for a period of time, a liquid outlet shell 211 is installed on the outer wall of the filter barrel 202. Under the action of the liquid outlet valve 212 installed at the port of the liquid outlet shell 211 through a conduit, the switch of the liquid outlet valve 212 is opened. Under the action of the liquid outlet shell 211 being located at the bottom of the filter barrel 202 and the connection between the two being a communicating structure, the mixed liquid in the inner cavity of the filter barrel 202 is discharged through the liquid outlet valve 212.

When the pressurized air pump 404 is running, suction is generated to inhale the mixed gas inside the air inlet pipe 403. The interior of the air inlet pipe 403 lacks gas and a negative pressure environment is generated. Under the action of the air outlet pipe 206 connected to one end of the air inlet pipe 403, The air inlet pipe 403 sucks the mixed gas inside the air outlet tube 207 through the air outlet pipe 206, and then the pressurized air pump 404 discharges the mixed gas into the interior of the reaction vessel 402. Under the action of the catalyst provided in the inner cavity of the reaction vessel 402, the mixed gas is adsorbed and catalyzed by the catalyst to obtain carbon monoxide gas with higher purity. The carbon monoxide gas can then be collected and reused, which is beneficial to solving the problem that the exhaust gas of the calcium carbide furnace contains a large amount of CO. It is also a usable energy medium. According to the characteristics of the exhaust gas of the calcium carbide furnace, the exhaust gas of the calcium carbide furnace can be collected and purified. The existing exhaust gas recovery device of the calcium carbide furnace has a weak function of recycling carbon monoxide.

The electronic barometer 505 generates an electrical signal that is transmitted to the control panel 3 through a wire. The control panel 3 displays the air pressure data inside the gas storage pipe 504 in real time. Under the action of a gas storage tank 506 installed on one end of the positioning bracket 501 and extending to the inner wall of the positioning bracket 501, the high-purity carbon monoxide gas obtained by the reaction of the post-processing component 4 enters the interior of the gas storage tank 506 through the gas storage pipe 504 for storage. A handle 507 is installed on one side of the gas storage tank 506 and on the outer wall of the positioning bracket 501. The outer wall of the gas storage tank 506 is connected to an outlet valve 508 through a conduit, so that the gas storage tank 506 can be lifted by the handle 507, and it can be stored and transported, or the high-purity carbon monoxide gas can be transmitted and used by connecting a conduit to one end of the outlet valve 508. The practicality of the device is better and it is conducive to flexible use in different work scenarios.
