Description

Technical Field

[0001] This utility model relates to the field of environmental waste treatment technology, and in particular to a desulfurization device for industrial waste gas filtration treatment. Background Technology

[0002] In the process of treating environmental waste, exhaust gas is often treated, which requires the use of desulfurization equipment. Desulfurization is achieved by the exhaust gas entering from the bottom of the desulfurization tower and reacting with the desulfurization agent sprayed from the top of the tower. However, the filter screen in the current desulfurization equipment is installed in the pipeline and is not easy to disassemble, which increases the complexity of cleaning and increases the workload of cleaning personnel.

[0003] Existing technologies, such as CN218011700U, involve releasing the limiting mechanism from the moving block, then maneuvering the moving block out of the fixed groove, exposing the top of the filter screen. The filter screen can then be removed along the top through groove and cleaned. After cleaning, the filter screen is pushed back in along the top through groove until its bottom enters the bottom groove. The moving block is then pushed back in along the fixed groove until the mating groove abuts against the top of the filter screen, thus completely fixing it. Finally, the limiting mechanism is used to fix the moving block. The bottom groove fixes the bottom of the filter screen, the mating groove fixes the top, and the top through groove guides the movement of the filter screen, allowing for detachable installation of the filter screen by moving the moving block. The entire process is simple and reduces the workload of cleaning personnel.

[0004] While the aforementioned patent addresses the issue of filter screens being difficult to disassemble when installed in pipes, increasing the complexity of cleaning and thus increasing the workload for cleaning personnel, the process still requires manual removal of the filter components, manual cleaning of the filter screen, and manual reinstallation of the filter screen after cleaning. The overall cleaning process is cumbersome and time-consuming, affecting cleaning efficiency. Summary of the Invention

[0005] The purpose of this utility model is to provide a desulfurization equipment for industrial waste gas filtration and treatment, which solves the problem that it is still necessary to manually remove the filter elements, then manually clean the filter screen, and then manually reinstall the filter screen after cleaning. The whole cleaning process is cumbersome and time-consuming, which affects the cleaning efficiency.

[0006] To achieve the above objectives, this utility model provides a desulfurization equipment for industrial waste gas filtration and treatment, including a tower body, an inlet pipe, an outlet pipe, and a spray pipe. The spray pipe is installed on the tower body, and the inlet pipe and outlet pipe are respectively installed on one side and the top of the tower body. It also includes auxiliary devices.

[0007] The auxiliary device includes a water tank located on one side of the tower body. A mounting bracket is installed on the top of the water tank by screws. Connector 1 and connector 2 are fixedly connected to both sides of the mounting bracket. Connector 2 is connected to the air inlet pipe through a flange. A sealing block is slidably connected to the inner wall of the mounting bracket. Filter element 1 and filter element 2 are fixedly connected to the inner wall of the sealing block. A cylinder is installed on one side of the mounting bracket, and its output end is fixedly connected to the sealing block. Spray head 1 and spray head 2 are installed on the inner wall of the mounting bracket. A water supply section is provided on the water tank. Two upper return pipes and a lower return pipe are installed on the surfaces of the mounting bracket and the water tank by screws. A collection section is provided between the upper return pipes and the lower return pipes.

[0008] The outer surface of the sealing block is fixed with a sealing gasket.

[0009] The water supply unit includes pump one and pump two installed on the surface of the water tank. The output end and input end of pump one are respectively fixedly connected to pipe one and pipe two. The output end and input end of pump two are respectively fixedly connected to pipe three and pipe four. The other ends of pipe one and pipe three are respectively installed on nozzle one and nozzle two by screws. The other ends of pipe two and pipe four extend into the water tank. During operation, when pump one or pump two is turned on, pipe two or pipe four draws liquid and then supplies it to nozzle one or nozzle two through pipe one or pipe two, thereby cleaning filter one or filter two.

[0010] The collection unit includes a box installed between the upper return pipe and the lower return pipe. A filter box is inserted into the inner wall of the box. After rinsing and cleaning, the liquid containing impurities enters the box through the upper return pipe, is filtered by the filter box, and the filtered liquid is discharged into the water tank through the lower return pipe.

[0011] The inner wall of the housing is rotatably connected to a rotating shaft, and one end of the rotating shaft is fixedly connected to a stop block. Through the above components, when the filter box is inserted into the housing, the rotating shaft is rotated, and the rotating shaft drives the stop block to rotate, so that the stop block abuts against the surface of the filter box.

[0012] The rotating shaft is fitted with a spring, and the two ends of the spring are fixedly connected to the surfaces of the rotating shaft and the housing, respectively. Through the above components, the spring can drive the rotating shaft to return to its original position, thereby improving the overall stability.

[0013] This utility model discloses a desulfurization device for industrial waste gas filtration. During cleaning, a cylinder drives a sealing block to move. When filter element one or filter element two aligns with nozzle one or nozzle two, the water supply unit supplies water to nozzle one or nozzle two, causing it to rinse filter element one or filter element two. The rinsed impurities enter the filtration section through the upper return pipe for filtration, and after filtration, they enter the water tank through the lower return pipe. There is no need for manual disassembly and cleaning, which improves the overall ease of use. Attached Figure Description

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figures 1-5 A desulfurization device for industrial waste gas filtration and treatment includes a tower body, an inlet pipe, an outlet pipe, and a spray pipe. The spray pipe is installed on the tower body, and the inlet pipe and outlet pipe are respectively installed on one side and the top of the tower body. It also includes auxiliary devices.

[0023] Specifically, the auxiliary device includes a water tank located on one side of the tower body. A mounting bracket is installed on the top of the water tank by screws. Connector 1 and Connector 2 are fixedly connected to both sides of the mounting bracket. Connector 2 is connected to the air inlet pipe through a flange. A sealing block is slidably connected to the inner wall of the mounting bracket. A sealing gasket (not shown in the figure) is fixed to the outer surface of the sealing block. Filter element 1 and Filter element 2 are fixedly connected to the inner wall of the sealing block. A cylinder is installed on one side of the mounting bracket, and its output end is fixedly connected to the sealing block. Spray head 1 and Spray head 2 are installed on the inner wall of the mounting bracket. A water supply section is provided on the water tank. Two upper return pipes and a lower return pipe are installed on the surfaces of the mounting bracket and the water tank by screws. A collection section is provided between the upper return pipes and the lower return pipes.

[0024] In this embodiment: During cleaning, the sealing block is moved by the cylinder. When filter element one or filter element two is aligned with nozzle one or nozzle two, the water supply unit supplies water to nozzle one or nozzle two, so that it washes filter element one or filter element two. The impurities after washing enter the filter unit for filtration through the upper return pipe. After filtration, they enter the water tank through the lower return pipe. There is no need for manual removal and cleaning, which improves the overall ease of use.

[0025] Specifically, the water supply unit includes pump one and pump two installed on the surface of the water tank. The output end and input end of pump one are respectively fixedly connected to pipe one and pipe two. The output end and input end of pump two are respectively fixedly connected to pipe three and pipe four. The other ends of pipe one and pipe three are respectively installed on nozzle one and nozzle two by screws. The other ends of pipe two and pipe four extend into the water tank.

[0026] In this embodiment: During operation, pump one or pump two is turned on, at which time pipe two or pipe four draws liquid, which is then fed to nozzle one or nozzle two through pipe one or pipe two to clean filter element one or filter element two.

[0027] Specifically, the collection unit includes a box installed between the upper return pipe and the lower return pipe. A filter box is inserted into the inner wall of the box. A rotating shaft is rotatably connected to the inner wall of the box. A stop block is fixedly connected to one end of the rotating shaft. A spring is sleeved on the surface of the rotating shaft. The two ends of the spring are fixedly connected to the rotating shaft and the surface of the box, respectively.

[0028] In this embodiment: after the filter box is inserted into the housing, the rotating shaft is rotated, which drives the stop block to rotate, so that the stop block abuts against the surface of the filter box. The spring can drive the rotating shaft to return to its original position, thereby improving the overall stability. After rinsing and cleaning, the liquid containing impurities enters the housing through the upper return pipe, where the filter box filters the liquid. The filtered liquid is then discharged into the water tank through the lower return pipe.

[0029] Working Principle: During operation, the filter element 2 in the sealing block is aligned with connectors 1 and 2 by default. The pipe is then connected to connector 1, and exhaust gas enters connector 1, is filtered by filter element 2, and then enters the inlet pipe and tower body through connector 2. The spray pipe sprays desulfurization agent for desulfurization. When filter element 2 needs cleaning, the cylinder is opened, moving the sealing block to align filter element 1 with connectors 1 and 2. At this time, pump 2 is opened, driving pipe 4 to draw liquid, which is then discharged into nozzle 2 through pipe 3. Nozzle 2 washes filter element 2. After washing and cleaning, the liquid containing impurities enters the tank through the upper return pipe, where it is filtered. The filtered liquid is discharged into the water tank through the lower return pipe. When cleaning filter element 1, the cylinder moves the sealing block back to its original position, then pump 1 operates, and nozzle 1 sprays, achieving the cleaning operation. When concentrated cleaning of impurities is required, simply rotate the shaft; the spring is stressed, and when the stop block loses its obstruction of the filter box, the filter box can be pulled out for cleaning.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
