Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a cleaning system. Background Technology

[0002] A Venturi dust collector is a device that brings dust-laden gas into close contact with a liquid, using the inertial collision of water droplets and particles, as well as other effects, to capture particles or enlarge them.

[0003] Currently, some old Venturi dust collectors often suffer from problems such as flue blockage and severe scaling due to design flaws or long-term operation. Traditional cleaning relies on manual drilling operations, which require operators to enter confined spaces for cleaning, which is not only time-consuming and labor-intensive, but also affects the continuity of production.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1 As shown, this utility model discloses a cleaning system, including a Venturi tube 10. A scrubbing tower 11 is connected to the bottom throat of the Venturi tube 10. A first valve 1 is installed on the pipeline between the bottom throat of the Venturi tube 10 and the scrubbing tower 11. A liquid inlet pipe 22 is connected to the top of the Venturi tube 10, and a second valve 2 is installed on the liquid inlet pipe 22. An air inlet pipe 19 is connected to the side of the Venturi tube 10, and a third valve 3 is installed on the air inlet pipe 19. Waste gas enters the Venturi tube 10 through the air inlet pipe 19, and acid solution enters the Venturi tube 10 through the liquid inlet pipe 22. After mixing, the two solutions enter the scrubbing tower 11.

[0032] The Venturi tube 10 is connected to a circulating cleaning pipeline, which is equipped with an alkali tank 12, a circulating pump 14 and a filter 13. Under the operation of the circulating pump 14, the alkali solution continuously circulates between the alkali tank 12, the Venturi tube 10 and the filter 13 to clean the inside of the Venturi tube 10.

[0033] The circulating cleaning pipeline includes an upper liquid pipe 16 connecting the lower part of the alkali tank 12 and the lower part of the venturi tube 10. A circulating pump 14 and a fourth valve 4 are sequentially installed on the upper liquid pipe 16. A return liquid pipe 20 is connected to the air inlet pipe 19 between the third valve 3 and the venturi tube 10. The return liquid pipe 20 is connected to the alkali tank 12. A filter 13 is installed on the return liquid pipe 20. A fifth valve 5 is also installed on the return liquid pipe 20 between the filter 13 and the air inlet pipe 19.

[0034] The circulating cleaning pipeline is equipped with an exhaust pipeline, which includes a main exhaust pipe 17 connected to the air inlet pipe 19 between the third valve 3 and the venturi pipe 10. The other end of the main exhaust pipe 17 is connected to the pipeline between the first valve 1 and the scrubbing tower 11. In the direction away from the air inlet pipe 19, the main exhaust pipe 17 is sequentially equipped with a sixth valve 6, a check valve 15, and a seventh valve 7. The main exhaust pipe 17 between the sixth valve 6 and the check valve 15 is connected to a secondary exhaust pipe 18, which is connected to the top of the alkali tank 12. The secondary exhaust pipe 18 is equipped with an eighth valve 8.

[0035] The intake pipe 19 is also connected to a drying pipe 21, which is connected to the intake pipe 19 between the third valve 3 and the venturi pipe 10. The drying pipe 21 is equipped with a ninth valve 9 and is used to transport hot nitrogen.

[0036] When the Venturi tube 10 is working normally, all valves are closed except for the first valve 1, the second valve 2, and the third valve 3 which are open.

[0037] During the cleaning of the Venturi tube 10, all valves except the first valve 1, the second valve 2, the third valve 3, and the ninth valve 9 are open. The circulating pump 14 pumps the alkali solution in the alkali tank 12 to the Venturi tube 10 through the upper liquid pipe 16. The alkali solution flows upward in the Venturi tube 10 and enters the air inlet pipe 19. Then, it flows back through the return liquid pipe 20, is filtered by the filter 13, and flows back to the alkali tank 12. This achieves the circulation of alkali solution between the alkali tank 12, the Venturi tube 10, and the filter 13, cleaning the inside of the Venturi tube 10. During this process, the gas generated by the reaction of the alkali solution with the residual silicon powder in the pipeline, as well as the gas in the system, enter the scrubbing tower 11 through the auxiliary exhaust pipe 18 and the main exhaust pipe 17 and are discharged.

[0038] After cleaning the Venturi tube 10, except for the first valve 1 and the ninth valve 9 which are fully opened, all other valves are closed. Hot nitrogen gas enters the inlet pipe 19 and the Venturi tube 10 through the drying pipe 21 to dry the interior. After drying is completed, the Venturi tube 10 can continue to work.

[0039] This invention uses alkaline solution to clean the Venturi tube 10. During the cleaning process, the alkaline solution is circulated and filtered, which can reduce the amount of lime used and realize online cleaning of the Venturi tube 10 without manual operation, greatly improving efficiency, avoiding or reducing the impact on production continuity, eliminating the need for frequent loop opening, and reducing the risk of personnel injury and environmental pollution caused by loop opening.

[0040] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
