Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production technology, specifically to a waste gas treatment device. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. The production process of lubricating oil generates a large amount of waste gas, thus requiring waste gas treatment equipment to purify it. However, most existing treatment devices only use a purification screen to purify the waste gas. Since the waste gas contains grease, and grease is viscous, oil droplets or mist in the waste gas adhere to the surface of the screen's fibers or pores as they pass through. Over time, more and more grease accumulates, gradually occupying the pores of the screen, narrowing the gas passageway, causing blockage, and significantly reducing the lifespan of the purification screen. This necessitates frequent and regular cleaning by staff, resulting in low purification efficiency. Utility Model Content

[0003] In view of this, the present invention provides a waste gas treatment device that can remove grease from the waste gas before purifying it, thereby reducing the damage to the purification screen caused by the waste gas, extending the service life of the device, eliminating the need for frequent cleaning of the purification screen by staff, and improving purification efficiency.

A filter pipe is provided on the upper side of one side of the barrel body, and a purification screen is provided inside the filter pipe. This filter pipe can remove grease in the waste gas before purifying the waste gas, thereby reducing the damage of grease in the waste gas to the purification screen, improving the service life of the device, eliminating the need for frequent cleaning of the purification screen by personnel, and improving purification efficiency.

[0005] A rotary joint is provided at the upper end of the feed pipe, and the feed pipe is rotatably set in the inner ring of the sealing ring. A driving component is provided at the upper part of the barrel, which is used to drive the feed pipe to rotate, so that the connecting pipe can spray cleaning liquid while rotating.

[0007] A scraper is installed on the side wall of the connecting pipe, and the end face of the scraper is in contact with the inner wall of the tank. When the connecting pipe rotates, the scraper can scrape off the residual liquid on the inner wall of the tank, improving the cleaning effect.

[0008] A baffle is installed on the lower inner wall of the barrel, directly above the air inlet pipe. The baffle can block the liquid and prevent the liquid after the grease is removed from flowing back into the air inlet pipe.

[0009] The baffle has an inverted V-shaped cross-section, which allows the liquid to flow to both sides of the baffle.

[0010] The surface of the baffle is covered with a Teflon film. The smooth surface of the Teflon film reduces wear on the scraper and extends its service life.

[0020] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown: This embodiment provides a waste gas treatment device, including a barrel 100, an air inlet pipe 500 is provided on one side of the bottom of the barrel 100, a sewage pipe 103 is provided at the center of the bottom of the barrel 100, a sealing ring 101 is provided on the upper part of the barrel 100, a feed pipe 200 is sleeved on the inner ring of the sealing ring 101, connecting pipes 400 are provided on both sides of the lower part of the feed pipe 200, a plurality of nozzles 401 are provided on the surface of the connecting pipes 400, and a filter pipe 601 is provided on the upper side of one side of the barrel 100, and a purification screen 602 is provided inside the filter pipe 601.

[0021] After the staff connects the air inlet pipe 500 to the exhaust port of the external equipment, the exhaust gas enters the tank 100 through the air inlet pipe 500. Then, alkaline cleaning solution is poured in through the feed ring, and the cleaning solution enters the connecting pipe 400 through the feed pipe 200. The cleaning solution is sprayed into the tank 100 through the nozzle 401 on the surface of the connecting pipe 400, causing the cleaning solution and the grease in the exhaust gas to undergo saponification, making the grease a water-soluble substance and dissolving and removing it. The liquid after grease removal is discharged from the tank 100 through the drain pipe 103, while the exhaust gas after grease removal is discharged from the tank 100 through the filter pipe 601. At the same time, the purification screen 602 in the filter pipe 601 can purify the exhaust gas, thereby removing the grease in the exhaust gas before purification, which can reduce the damage of the purification screen 602 to the exhaust gas, improve the service life of the device, eliminate the need for staff to clean the purification screen 602 frequently, and improve the purification efficiency.

The feed pipe 200 can be driven to rotate within the inner ring of the sealing ring 101 by the drive component. The feed pipe 200 drives the connecting pipe 400 to rotate synchronously, so that the connecting pipe 400 can spray the cleaning fluid while rotating. By increasing the spray range of the cleaning fluid, the removal effect of grease in the exhaust gas is improved.

[0030] according to Figure 2 As shown, a Teflon film is fitted onto the surface of the baffle 102;

[0031] The Teflon film has a smooth surface, which reduces wear on the scraper 402 and extends its service life.
