Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection equipment, in particular to a high-efficiency desulfurization device. Background Art

[0002] High-efficiency desulfurization devices are commonly used environmental protection equipment in the industrial and energy fields. Their main purpose is to reduce sulfur dioxide (SO2) emissions generated during the combustion process and improve air quality. Sulfur dioxide is one of the main emissions after burning sulfur-containing fuels (such as coal, oil, etc.), which has potential negative effects on the environment and human health, such as the formation of acid rain and the aggravation of respiratory diseases.

[0003] After searching, the existing patent (Announcement No.: CN219942372U) discloses a high-efficiency spray desulfurization device, including an inner liner and an outer liner, the inner liner passes through the upper end cover of the outer liner; the space between the inner liner and the outer liner is closed at the top; a flue gas inlet is arranged at the upper end of the outer liner; a spiral channel is arranged between the inner liner and the outer liner, the upper end of the spiral channel is connected to the flue gas inlet; a spray head is also arranged at the upper end of the spiral channel; the lower end of the spiral channel is connected to the lower end of the inner liner, and the upper part of the inner liner is the flue gas outlet; the spiral channel is provided with a step. The advantages of the utility model are: the flue gas changes the desulfurization mode through multiple rotations in the tower, improves the desulfurization efficiency, and is easy to adjust; in addition, it also has the advantages of simple operation, high desulfurization efficiency, and easy adjustment.

[0004] However, in the actual use of the above scheme, mixing is an important factor to ensure that the concentration of the desulfurizer (such as limestone slurry or gypsum slurry) is always uniform. If the desulfurization device cannot effectively mix the desulfurizer, the concentration of the desulfurizer will be affected, resulting in a decrease in reaction efficiency, resulting in insufficient or poor removal rate of sulfur dioxide.

[0005] To this end, the utility model provides a high-efficiency desulfurization device. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art and solve the problem that the desulfurization device cannot effectively mix the desulfurizer, which will affect the concentration of the desulfurizer and lead to reduced reaction efficiency, resulting in insufficient or poor removal rate of sulfur dioxide, the utility model proposes a high-efficiency desulfurization device.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the utility model is a high-efficiency desulfurization device, including a desulfurization tower, the front side of the middle end of the desulfurization tower is fixedly connected with an air inlet, the outer side of the top of the desulfurization tower is fixedly connected with an air outlet, the inner side of the bottom end of the desulfurization tower is fixedly connected with a mixing tank, the middle side of the top of the mixing tank is fixedly connected with a motor, the output end of the motor is fixedly connected with a transmission rod, the outer side of the bottom end of the transmission rod is fixedly connected with a mixing rack, the outer side of the mixing tank is provided with a conveying assembly, and the bottom side of the top of the conveying assembly is provided with a spray assembly;

[0008] Through the above technical solution, the motor uses the transmission rod to drive the mixing rack to rotate, so that the desulfurizer in the mixing tank is always at a relatively uniform level, and the particles carried in the desulfurizer at the bottom can be transported upward through the mixing rack, thereby ensuring that no particles will accumulate at the bottom of the mixing tank to affect the concentration of the desulfurizer.

[0009] Furthermore, the delivery assembly includes a delivery pump, the front side of the top of the mixing tank is fixedly connected to the delivery pump, the right outer wall of the delivery pump is fixedly connected to front and rear opposite water inlet pipes, and the left outer wall of the delivery pump is fixedly connected to a water outlet pipe;

[0010] According to the above technical solution, the desulfurizer is extracted by the delivery pump through the water inlet pipe and delivered to the top spray assembly through the water outlet pipe.

[0011] Further, the spray assembly includes a rotating tube, the bottom right end of the water outlet pipe is rotatably connected to the rotating tube, the outer side of the rotating tube is fixedly connected to a uniformly distributed delivery pipe, the outer side of the delivery pipe is fixedly connected to a rotating joint, the outer side of the rotating joint is rotatably connected to a diverter head, the outer side of the middle end of the diverter head is fixedly connected to a uniformly distributed first atomizing head, and the outer outer wall of the diverter head is fixedly connected to a second atomizing head;

[0012] Through the above technical scheme, the desulfurizer is sprayed outward by atomization through the second atomizing head, thereby generating thrust to drive the conveying pipe and the rotating pipe to rotate. At the same time, the desulfurizer is sprayed outward by the outer first atomizing head to drive the diverter head to rotate, so that the desulfurizer can be sprayed more evenly after atomization, ensuring sufficient contact and mixing between the desulfurizer and the flue gas.

[0013] Furthermore, the splitter head is fixedly connected to the outer side of one end close to the delivery pipe with evenly distributed fan blades;

[0014] Through the above technical solution, the fan blades are driven to rotate by the diverter head, thereby generating wind force, pushing the desulfurizer sprayed after atomization to the rear end, thereby expanding the spraying area.

[0015] Furthermore, a fixing frame opposite to each other is fixedly connected to the inner side of the upper end of the desulfurization tower, and the fixing frame is rotatably connected to the rotating tube;

[0016] Through the above technical solution, the rotating tube is limitedly supported by the fixing frame.

[0017] Furthermore, an isolation plate is fixedly connected to the middle end of the inner side of the desulfurization tower;

[0018] Through the above technical solution, the space on the upper and lower sides of the desulfurization tower is separated by isolation plates, thereby preventing the desulfurizer from falling directly onto the bottom motor and delivery pump and affecting the operation.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The high-efficiency desulfurization device described in the utility model uses a motor to drive a mixing frame to rotate and mix the desulfurizer by using a transmission rod. Stirring the desulfurizer can ensure that it is mixed evenly, so that the concentration and quality of the desulfurizer remain consistent when it is sprayed. This helps to ensure the stability and predictability of the entire desulfurization process. At the same time, the stirring function is achieved through a simple structure, which also reduces the failure rate of the device.

[0021] 2. The high-efficiency desulfurization device described in the utility model generates power when the desulfurizer is sprayed out by the first atomizing head and the second atomizing head, which drives the diverter head to revolve and rotate at the same time, ensuring full mixing and contact with the flue gas. This can make the reaction more thorough and rapid, effectively absorb and convert sulfur dioxide in the flue gas, and improve the desulfurization efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
