Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to an RTO waste gas purification device. Background Art

[0002] RT0 is a high-efficiency organic waste gas treatment equipment. Its principle is to heat the organic waste gas to above 760 degrees Celsius, so that the volatile organic compounds in the waste gas are oxidized and decomposed into carbon dioxide and water. The high-temperature gas generated by oxidation flows through a special ceramic heat storage body, causing the ceramic body to heat up and store heat. This heat storage is used to preheat the subsequent organic waste gas, thereby saving fuel consumption for waste gas heating. Compared with traditional catalytic combustion and direct-fired thermal oxidation furnaces, it has the characteristics of high thermal efficiency, low operating cost, and the ability to handle large air volume and low-concentration waste gas. When the concentration is slightly higher, secondary waste heat recovery can also be carried out, greatly reducing production and operation costs.

[0003] A Chinese patent discloses an RTO waste gas treatment device (authorization announcement number CN217662234U), which produces cold air through an air conditioner, so that the cold air enters the cooling box from the ventilation pipe. The cold air will cool the inside of the collection box, so that the water vapor generated after the waste gas treatment is liquefied and drips into the collection box, so that the water vapor generated after the waste gas treatment can be reused to avoid waste of resources. However, according to actual conditions, when the water vapor enters the low-temperature cooling box, part of the water vapor will liquefy and drip into the collection box, while the other part of the water vapor will form water droplets and adhere to the inner wall of the cooling box after contacting the low-temperature cooling box. If it is not collected, it is easy to cause waste of water resources. Utility Model Content

[0022] A cleaning mechanism 8 is installed in the purification box 3. The cleaning mechanism 8 includes a motor 81, a transmission shaft 82 and a limiting cylinder 83. The motor 81 is fixed at the top center of the purification box 3, and the driving end of the motor 81 passes through the top of the purification box 3 and is fixed to the transmission shaft 82.

[0023] Among them, the model of the motor 81 is YE2.

[0024] Working principle: When using this device, inject a proper amount of water into the purification box 3 through the air inlet 32, and then inject exhaust gas into the purification box 3 through the air inlet 32. After the exhaust gas enters the water, the particulate matter and impurities in the exhaust gas are attached to the water. Then turn on the induced draft fan 5, which can drive the exhaust gas to pass through the activated carbon filter plate 33. At this time, the sulfide in the exhaust gas can be filtered and adsorbed by the activated carbon filter plate 33. Then the exhaust gas can be pumped into the heat storage chamber 1 and the combustion chamber 2. The exhaust gas is thermally oxidized under the action of the burner and decomposed into two Carbon dioxide and water vapor are oxidized, and the high-temperature gas generated by oxidation can heat and store heat when it flows through the ceramic heat storage body, so that the organic waste gas that enters later can be preheated, and carbon dioxide and water vapor enter the cooling box 4 through the pipe 6. At this time, the water vapor is liquefied and drips into the collection box 43 below, and the remaining water vapor adheres to the inner wall of the cooling box 4. At this time, the pressure plate 71 is pressed down by hand, so that the guide rod 72 and the scraper 74 can be driven downward. At this time, the spring 73 is in a compressed state. As the scraper 74 moves The spring 73 is gradually restored to its original shape, thereby driving the pressing plate 71, the guide rod 72 and the scraper 74 to move upward to restore them to their initial positions. When there are many sulfides and impurities attached to the bottom of the activated carbon filter plate 33, the first sealing plate 31 is opened first, and then the bolt 85 is loosened. Then, the limiting cylinder 83 is moved upward so that the cleaning rod 84 is against the bottom of the activated carbon filter plate 33, and then the screw is tightened. The bolt 85 is tightened, and then the first sealing plate 31 is closed, and the motor 81 is turned on. After the motor 81 is energized, it can drive the transmission shaft 82, the limiting cylinder 83 and the cleaning rod 84 to rotate. At this time, the rotating cleaning rod 84 can clean the sulfides and impurities attached to the bottom of the activated carbon filter plate 33 to avoid excessive accumulation of sulfides and impurities and causing blockage of the bottom of the activated carbon filter plate 33. This method has a good cleaning effect, and the height of the cleaning rod 84 is adjustable, so that it can be placed at the bottom of the activated carbon filter plate 33 for cleaning.
