Description

Technical Field

[0001] The utility model belongs to the technical field of desulfurization towers, in particular to a high-efficiency desulfurization component of a flue gas wet desulfurization tower. Background Art

[0002] With the acceleration of industrialization, the large-scale use of sulfur-containing fuels such as coal and oil has caused a sharp increase in the emission of pollutants such as sulfur dioxide in flue gas. Traditional desulfurization technology has exposed many problems in dealing with the growing high-sulfur flue gas. On the one hand, the desulfurization efficiency is difficult to meet the increasingly stringent environmental protection standards, resulting in a large amount of harmful gases being discharged into the atmosphere, causing environmental crises such as acid rain; on the other hand, existing desulfurization equipment often has shortcomings such as high energy consumption, easy clogging, and high maintenance costs, which brings a heavy burden to the continuous operation of enterprises. Against this background, it is urgent to develop efficient desulfurization components for wet flue gas desulfurization towers. Wet desulfurization often uses limestone solution to react with sulfur-containing gases to generate calcium sulfate solids to achieve desulfurization.

[0003] However, during use, the high-efficiency desulfurization components of the existing flue gas wet desulfurization tower are not convenient for filtering the reacted limestone solution and are difficult to separate the calcium sulfate solids contained therein. The calcium sulfate solids in the solution will clog the device, requiring staff to clean it, resulting in the interruption of the continuity of the desulfurization work. Utility Model Content

[0004] The utility model aims to provide a high-efficiency desulfurization component for a flue gas wet desulfurization tower. By setting a filtering mechanism, the utility model solves the problem that the high-efficiency desulfurization component of the existing flue gas wet desulfurization tower is not convenient for filtering the reacted limestone solution during use, and it is difficult to separate the calcium sulfate solids contained therein, and the calcium sulfate solids in the solution will clog the device, thereby requiring staff to clean it, resulting in the continuity of the desulfurization work being interrupted.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a high-efficiency desulfurization component of a flue gas wet desulfurization tower, comprising a box body, on which a filtering mechanism and a circulation mechanism are arranged;

[0007] The filtering mechanism includes a filtering barrel fixedly connected to the left side of the box body, a filter cartridge fixedly connected to the bottom inner wall of the filtering barrel, a spiral blade 1 rotatably connected to the bottom inner wall of the filtering barrel, the inner wall of the spiral blade 1 contacts the filter cartridge, the outer wall of the spiral blade 1 contacts the inner wall of the filtering barrel, and a slag outlet is connected to the outer wall of the filtering barrel.

[0008] Furthermore, a connecting block is rotatably connected to the inner wall of the top of the filter barrel, the bottom of the connecting block is fixedly connected to a spiral blade, the top of the connecting block is fixedly connected to a rotating shaft, the top of the rotating shaft rotates and extends outside the filter barrel, the top of the filter barrel is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to the rotating shaft via a coupling.

[0009] Furthermore, the circulation mechanism includes a liquid reflux component and a gas flow component, the liquid reflux component includes a leakage groove opened on the inner wall of the bottom of the box body, the leakage groove is connected to the filter barrel, and a rotating shaft 2 is rotatably connected on the right inner wall of the leakage groove, and the right side of the rotating shaft 2 rotates and extends outside the box body.

[0010] Furthermore, a second motor is fixedly connected to the right side of the box body, an output shaft of the second motor is fixedly connected to a second rotating shaft via a coupling, and a second spiral blade is fixedly connected to an outer wall of the second rotating shaft.

[0011] Furthermore, a connecting pipe 1 is provided at the bottom of the filter barrel, a water pump is fixedly connected to the left side of the box body, and the right side of the connecting pipe 1 is connected to the water pump.

[0012] Furthermore, a connecting pipe 2 is provided on the right side of the water pump, the right side of the connecting pipe 2 extends into the box body, a nozzle is fixedly connected to the top inner wall of the box body, and the right side of the connecting pipe 2 is connected to the nozzle.

[0013] Furthermore, the gas flow component includes two air inlet pipes which are connected and arranged on the left side of the box body, and an exhaust port is connected and arranged on the right side of the box body.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting a filtering mechanism, after the limestone solution containing calcium sulfate enters the filter barrel, the motor 1 can be started to rotate its output shaft. When the output shaft of the motor 1 rotates, the connecting block will be driven to rotate through the rotating shaft 1. When the connecting block rotates, the limestone solution containing calcium sulfate will be driven to move upward through the spiral blade 1. At this time, the limestone solution in the limestone solution containing calcium sulfate will enter the connecting pipe 1 through the filter cartridge, and the calcium sulfate will be discharged through the slag outlet, so that the reacted limestone solution can be filtered and the calcium sulfate solid therein can be separated, so as to avoid the calcium sulfate solid clogging the device and preventing it from interrupting the work process, thereby improving the work efficiency;

[0016] 2. By setting a circulation mechanism, the limestone solution is transferred from the connecting pipe 2 to the nozzle through the water pump, and then the spray pipe is transferred to the box body. At this time, the sulfur-containing gas can be transferred to the box body through the air inlet pipe. At this time, the sulfur in the sulfur-containing gas will react with the limestone solution to generate calcium sulfate, and its desulfurized gas will be discharged from the exhaust port, and the limestone solution containing calcium sulfate will fall into the leakage tank. Then the motor 2 can be started to rotate its output shaft. When the output shaft of the motor 2 rotates, the spiral blade 2 will be driven to rotate through the rotating shaft 2 to transport the limestone solution containing calcium sulfate to the filtering mechanism. After filtering, the clean limestone solution will flow back into the water pump, so that the limestone solution can repeatedly desulfurize the sulfur-containing gas to prevent a small amount of sulfur element from escaping into the natural environment with the gas. In addition, the limestone solution is reused so that the effective substances contained therein can fully react, thereby reducing the production cost;

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
