Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization and environmental protection, in particular to a spray-type dust removal and desulfurization tower. Background Art

[0002] A spray-type dust removal and desulfurization tower is an important industrial flue gas desulfurization equipment, primarily used to remove particulate matter and soluble gases from exhaust gas to achieve exhaust gas purification. Its main operating principle is to spray the filter layer with liquid within the tower, causing particulate matter in the exhaust gas to be absorbed by the liquid or adhere to the liquid surface. Simultaneously, the chemicals in the spray liquid react with sulfides in the gas, forming sulfates that precipitate, thereby purifying the flue gas.

[0003] In the prior art, when treating waste gas, the reaction rate between the waste gas and the catalyst in the desulfurization tower is slow, resulting in the discharge of unreacted waste gas and inadequate treatment.

[0004] The existing patent (publication number: CN207271069U) discloses a wet spray dust removal and desulfurization tower. By setting a spray plate, lime water and catalyst are introduced into the tower body through the spray plate, and the exhaust gas is sucked into the tower body through a suction fan. The interior of the tower body is provided with a stirring shaft and a heater, so that the exhaust gas can fully react with the lime water and multiple catalysts, thereby accelerating the reaction rate.

[0005] In response to the above problems, although the solution provided by the existing patent uses a stirring shaft to stir the exhaust gas and the catalyst to accelerate the reaction, the catalyst is at the bottom of the desulfurization tower, and the exhaust gas is discharged from the top after entering the desulfurization tower. Such a setting still makes the contact time between the exhaust gas and the catalyst short, resulting in poor reaction effect. Summary of the Invention

[0006] The purpose of this utility model is to provide a spray-type dust removal and desulfurization tower, which can drive the impeller to rotate when the desulfurizer is transported and sprayed, so that the transmission pipe will drive the two sets of spray parts to rotate, thereby improving the contact effect between the liquid and the exhaust gas, ensuring the desulfurization efficiency of the exhaust gas, and solving the problems raised in the above background technology.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A spray-type dust removal and desulfurization tower includes a desulfurization tower body 1, an outer wall of the desulfurization tower body 1 is connected to an air inlet pipe 2, an upper surface of the desulfurization tower body 1 is connected to an exhaust pipe 3, a lower end of the interior of the desulfurization tower body 1 is provided with a conveying mechanism for conveying a desulfurizer, and a limiting mechanism for fixing the conveying mechanism is fixed inside the desulfurization tower body 1;

[0028] The conveying mechanism includes a liquid storage chamber 4, which is opened at the lower end of the desulfurization tower body 1. A high-pressure pump 41 connected to the liquid storage chamber 4 is installed on the left side of the desulfurization tower body 1. The output end of the high-pressure pump 41 is connected to a conveying pipe 42, and the end of the conveying pipe 42 is connected to a connecting piece 43. An impeller 44 is installed inside the connecting piece 43. A transmission pipe 45 is fixed to the lower surface of the impeller 44. A through hole 46 is opened on the outer wall of the transmission pipe 45. A flow chamber 47 connected to the through hole 46 is opened inside the transmission pipe 45. Two groups of spraying parts 48 connected to the flow chamber 47 are provided on the outer surface of the transmission pipe 45. A plurality of spray holes 49 are opened on the lower surface of the spraying part 48. The limiting mechanism includes a fixed frame 5, which is fixed to the inside of the desulfurization tower body 1. A fixed bearing 51 sleeved on the outer wall of the transmission pipe 45 is inlaid inside the fixed frame 5. A sealing groove 52 is opened inside the fixed frame 5. The sealing groove 52 is connected to a sealing ring 53 fixed to the transmission pipe 45.

[0029] By adopting the above technical solution, before using the spray-type dust removal and desulfurization tower, the desulfurization tower body 1 is first placed in a suitable position, the air inlet pipe 2 is connected to the external exhaust gas conveying equipment, and the liquid desulfurizer is stored in the liquid storage chamber 4. When the exhaust gas enters the desulfurization tower body 1, the high-pressure pump 41 extracts the desulfurizer and sends it to the connecting piece 43 through the delivery pipe 42. After the high-pressure liquid enters, it will first drive the impeller 44 to rotate, so that the impeller 44 drives the transmission pipe 45 to rotate, and the liquid that drives the impeller 44 to rotate enters the transmission pipe 45 through the through hole 46, and then passes through the transmission pipe 45. The liquid flows into the two groups of spray parts 48 through the flow cavity 47 respectively. At this time, the two groups of spray parts 48 spray liquid downward through the spray holes 49. At the same time, the transmission pipe 45 drives the two groups of spray parts 48 to rotate, thereby improving the contact effect between the liquid and the exhaust gas and ensuring the desulfurization efficiency of the exhaust gas. The fixed frame 5 is provided to ensure the stability of the connecting part 43, and the fixed bearing 51 is provided to ensure the stability of the transmission pipe 45 during rotation. With the cooperation of the sealing groove 52 and the sealing ring 53, a certain sealing effect can be achieved, thereby reducing the leakage of liquid in the connecting part 43.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, a filter screen 6 is fixed in the horizontal direction inside the desulfurization tower body 1, two fixing rings 7 are fixed on one side of the desulfurization tower body 1, the end of the exhaust pipe 3 is connected to a negative pressure fan 8, and the output end of the negative pressure fan 8 is connected to an air outlet pipe 9. The outer surface of the desulfurization tower body 1 is hingedly connected to a door panel 10, and the outer wall of the desulfurization tower body 1 is provided with a liquid filling port 11 which is interconnected with the liquid storage chamber 4. The lower end of the outer wall of the desulfurization tower body 1 is provided with a waste liquid pipe 12 which is interconnected with the liquid storage chamber 4, and a valve is fixed to the outer wall of the waste liquid pipe 12.

[0031] By adopting the above technical solution, the sprayed desulfurization liquid will fall onto the filter 6 after contacting the exhaust gas. The filter 6 filters the impurities in the liquid, allowing the liquid to re-enter the liquid storage chamber 4 for recycling. The set fixing ring 7 can strengthen the fixation of the exhaust pipe 3. The desulfurized exhaust gas is drawn out by the negative pressure fan 8 through the exhaust pipe 3, and then discharged to the outside through the air outlet pipe 9. By opening the door panel 10, it is convenient to clean the impurities on the filter 6. By opening the valve on the waste liquid pipe 12, the desulfurization liquid in the liquid storage chamber 4 can be discharged for replacement, and the desulfurizer can be added to the liquid storage chamber 4 through the liquid filling port 11 for easy use.

[0032] Working principle: The high-pressure pump 41 extracts the desulfurizer and sends it to the connecting part 43 through the delivery pipe 42. After the high-pressure liquid enters, it will first push the impeller 44 to rotate, so that the impeller 44 drives the transmission pipe 45 to rotate. The liquid after pushing the impeller 44 to rotate enters the transmission pipe 45 through the through hole 46, and flows into the two groups of spray parts 48 through the flow cavity 47. The two groups of spray parts 48 spray liquid downward through the spray holes 49. The transmission pipe 45 will drive the two groups of spray parts 48 to rotate, thereby improving the contact effect between the liquid and the exhaust gas and ensuring the desulfurization efficiency of the exhaust gas. The fixed bearing 51 can ensure the stability of the transmission pipe 45 during rotation. With the cooperation of the sealing groove 52 and the sealing ring 53, it can play a certain sealing effect. The filter screen 6 filters the impurities in the liquid, and the liquid enters the liquid storage chamber 4 again for recycling. By opening the door panel 10, it is convenient to clean the impurities on the filter screen 6.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
