Description

Technical Field

[0001] The utility model relates to the field of gas recovery devices, in particular to a gas recovery device with self-cleaning of the inner wall of an air cavity. Background Art

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life. In particular, chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries emit strong odors, seriously polluting the environment and affecting human health. Traditional organic waste will produce a large amount of harmful gases during the treatment process, so it is necessary to use gas recovery devices to recycle the waste gas during the treatment process;

[0003] A Chinese patent with publication number CN220968523U discloses a gas recovery device that is easy to clean, and in particular relates to a gas recovery device, including a recovery tank, wherein the left side surface of the recovery tank is connected to one end of a liquid inlet pipe, and the lower surface of the recovery tank is connected to one end of a liquid discharge pipe. A servo motor drives a connecting sleeve and a connecting pipe to rotate, and the rotation of the connecting pipe drives a fixed sleeve and a stirring blade to rotate, and the rotation of the fixed sleeve drives a scraper a to rotate to scrape off impurities adhered to the surface of an air filter, and the rotation of the stirring blade drives a scraper b to rotate to scrape off impurities adhered to the bottom of the recovery tank, thereby preventing solid impurities from clogging the air filter and preventing solid impurities from adhering to the inner wall of the recovery tank, reducing the difficulty of cleaning, and solving the problem that the existing device is not provided with a cleaning mechanism, and therefore needs to regularly replace the air filter, and the replacement process is cumbersome, which affects the gas recovery efficiency.

[0004] The gas recovery device of the above patent recovers waste gas because the waste gas is divided into multiple categories, including waste gas generated by oil evaporation. When this type of waste gas enters the gas recovery device, because the gas contains oil mist, when it condenses on the inner wall of the gas recovery device and turns into oil again, it mixes with dust in the air and may adhere to the inner wall of the gas recovery device. Due to its high viscosity, the cleaning effect may not be ideal if only a scraper is used. Utility Model Content

When the gas recovery device starts to work, gas is discharged from the gas recovery device to the gas recovery device. An air inlet pipe arranged at the lower end of the collection device enters into the gas recovery device. When the exhaust gas needs to be transferred, the transfer of the exhaust gas can be completed by connecting another gas storage tank to the connecting flange on the air outlet pipe through the air supply pipe. When the inner wall of the gas recovery device needs to be cleaned, the rotating motor drives the transmission shaft to rotate, and the first brush and the second brush scrape off the dust on the upper and lower ends of the inner wall of the gas recovery device, and the gear abuts against the side of the inner wall of the gas recovery device. As the transmission shaft rotates, each tooth on the gear contacts the inner wall of the gas recovery device in turn, and the viscosity of the solidified oil is used to hook up the oil from the inner wall of the gas recovery device by the teeth, and then adhere to the sponge pad with a large number of fine holes, thereby playing a cleaning role and solving the problems raised in the above-mentioned background technology.
