[0002] A scrubber is a common gas treatment device that can effectively remove harmful substances in the waste gas generated during industrial production processes. It is commonly used in industries such as chemical engineering, pharmaceuticals, and food processing. In these industries, scrubbers are widely used in waste gas treatment to ensure environmental safety and ecological protection during the production process. It is improved on the basis of a floating packing layer gas purifier and is widely used in the pretreatment of industrial waste gas purification, dust removal, etc., with good purification effects.

[0003] In the prior art, there are still certain deficiencies in the use of water circulation acid and dust removal scrubbers. Since the waste gas contains a certain amount of soot, traditional scrubbers usually rely on the packing layer to filter the soot, resulting in a relatively large amount of soot remaining inside the packing layer, causing the packing layer to be blocked, affecting the smoothness of the internal gas, having a short service life of the packing layer, and requiring regular replacement of the packing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water circulation acid and dust removal scrubber to solve the problems mentioned in the above background technique, that is, since the waste gas contains a certain amount of soot, traditional scrubbers usually rely on the packing layer to filter the soot, resulting in a relatively large amount of soot remaining inside the packing layer, causing the packing layer to be blocked, affecting the smoothness of the internal gas, having a short service life of the packing layer, and requiring regular replacement of the packing.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water circulation acid and dust removal scrubber, including a main body of the acid and dust removal scrubber. Inside the main body of the acid and dust removal scrubber, a spray head, a packing layer, and an inclined plane holder are sequentially arranged from top to bottom. A dust filter plate is arranged inside the inclined plane holder. At the lower end position of the bottom surface of the inclined plane holder, a waterproof diversion cover is arranged. At the upper end position of the bottom surface of the inclined plane holder, a flushing head assembly seat is arranged. A dust flushing head is arranged inside the flushing head assembly seat. A sediment storage tank is arranged at the bottom of the main body of the acid and dust removal scrubber. A cleaning port is arranged at the front end of the sediment storage tank. A sediment guiding groove is arranged between the sediment storage tank and the main body of the acid and dust removal scrubber. A common base is arranged below the sediment storage tank. A medicine adding barrel and a circulation water tank are respectively arranged at the rear end above the common base. The spray head is connected to a water delivery pipe. The lower end of the water delivery pipe is connected to the circulation water tank through a second circulation water pump. A pump seat is arranged below one side of the main body of the acid and dust removal scrubber. A first circulation water pump is arranged above the pump seat. A clean gas outlet is arranged at the top of the main body of the acid and dust removal scrubber. An exhaust gas inlet is arranged below the other side of the main body of the acid and dust removal scrubber.

[0006] In a further embodiment, the waterproof diversion cover is connected to the waste gas inlet by welding, and the cross-section of the waterproof diversion cover is set as an eighth-circular structure.

[0007] In a further embodiment, the precipitation storage tank is connected to the main body of the deacidification and dust removal scrubbing tower by welding with a support rod, the precipitation guide groove and the precipitation storage tank are set as an integral structure, and the outer shape of the precipitation guide groove is set as an inverted conical structure.

[0008] In a further embodiment, the inlet end of the first circulation water pump is fixedly connected to the main body of the deacidification and dust removal scrubbing tower through a water inlet connecting pipe, and the outlet end of the first circulation water pump is fixedly connected to the flushing head assembly seat through a water outlet connecting pipe.

[0009] In a further embodiment, the dust filter plate is fixedly connected to the inclined surface holder by bolts, and the inclined surface holder is connected to the inner wall of the main body of the deacidification and dust removal scrubbing tower by welding.

[0010] In a further embodiment, the dust flushing head is fixedly connected to the flushing head assembly seat by threads, and the number of the dust flushing heads is set to four in total.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, a dust filter plate is provided inside the inclined surface holder. Through the dust filter plate, the soot and solid particulate matter in the waste gas can be filtered and blocked, preventing the dust from floating upwards with the gas and avoiding dust accumulation inside the packing layer, which may cause blockage. Thus, the service life of the packing layer is prolonged, the cost is reduced. By setting it as an inclined surface structure, the dust accumulated on the surface can slide downwards, reducing the amount of dust on the surface. And at the upper end position of the bottom surface of the inclined surface holder, there is a dust flushing head. Through the dust flushing head, the dust filter plate can have an automatic cleaning function. This structure can circulate and spray the waste liquid collected at the bottom of the tower to wash the bottom surface of the dust filter plate, keeping the inside of the dust filter plate unobstructed. The structural principle is simple, and the effect of reusing the waste liquid can be achieved, thus saving energy and being easier to operate. BRIEF DESCRIPTION OF THE DRAWINGS
