Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology, and in particular to an atomizing device for semi-dry desulfurization. Background Technology

[0002] In industrial production, semi-dry desulfurization technology has been widely used in the field of flue gas desulfurization due to its advantages such as high efficiency, economy and environmental protection. Semi-dry desulfurization atomization uses an atomizer to atomize the slurry containing desulfurizing agent into fine droplets, which are then sprayed into the desulfurization reaction tower. These fine droplets have a large specific surface area, which can fully contact and chemically react with acidic gases such as sulfur dioxide in the flue gas, thereby achieving the purpose of desulfurization.

[0003] Currently, most semi-dry desulfurization atomization devices directly deliver flue gas into the device and allow it to contact the atomized desulfurizing agent droplets. However, this method lacks a proper flue gas flow guiding structure, making it impossible to change the flow direction and velocity of the flue gas. Consequently, it cannot allow the flue gas to encounter the atomized desulfurizing agent droplets at different angles and speeds. Therefore, we propose a semi-dry desulfurization atomization device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an atomizing device for semi-dry desulfurization to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A semi-dry desulfurization atomizing device includes a desulfurization tower body. A discharge valve is connected to the inner bottom wall of the desulfurization tower body. Two sets of fixing blocks are connected to the inner wall of the desulfurization tower body. A fixing plate is connected to one side of the two sets of fixing blocks that are close to each other. A pressurization chamber is opened inside the fixing plate. A set of spray heads is opened on the bottom surface of the fixing plate. A desulfurizing agent holding tank is connected to the outer surface of the desulfurization tower body. A filling port is opened on the upper surface of the desulfurizing agent holding tank. A booster pump is installed inside the desulfurizing agent holding tank. The output end of the booster pump is connected to a delivery pipe. The output end of the conveying pipe passes through the inner wall of the desulfurizing agent container and the inner wall of the desulfurization tower body in sequence and is connected to the upper surface of the fixed plate. The outer surface of the desulfurization tower body is connected to a U-shaped cylinder. The left side of the U-shaped cylinder is connected to a flue gas inlet. Two sets of sealed bearings are embedded in the inner wall of the U-shaped cylinder. The inner walls of the two sets of sealed bearings are connected to a connecting rod. The outer surface of each connecting rod is connected to a guide plate. A micro motor is installed at the front end of one of the connecting rods. The front and back sides of two of the guide plates are connected to a connecting plate.

[0007] In a further embodiment, the front of the spiral tube is connected to an arc-shaped seat, and the upper surface of the arc-shaped seat is connected to the outer surface of the micro motor.

[0008] In a further embodiment, the upper surface of the desulfurization tower body is connected to a flue gas outlet, and the inside of the flue gas outlet is connected to filter cotton.

[0009] In a further embodiment, an observation window is provided on the front of the desulfurization tower body, and the interior of the observation window is connected with transparent glass.

[0010] In a further embodiment, the outer surface of the desulfurization tower body is connected to two reinforcing seats, and the upper surfaces of the two reinforcing seats are respectively connected to the bottom surface of the desulfurizing agent holding box and the bottom surface of the U-shaped cylinder.

[0011] In a further embodiment, the desulfurization tower body is connected to an annular plate, and the bottom surface of the annular plate is connected to two sets of support rods. The bottom end of each support rod is connected to an installation plate, and each installation plate has a set of installation holes inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device first uses a micro motor to drive one connecting rod and one guide plate to rotate. This allows the two connecting plates to work together to drive the other two connecting rods and two more guide plates to rotate. This enables the operator to fine-tune the guiding angle of multiple guide plates, thereby adjusting the angle at which the flue gas enters the desulfurization tower. This ensures more uniform contact between the flue gas and the mist droplets generated by the desulfurizing agent. Attached Figure Description

[0022] Please see Figure 1-4In this utility model, an atomizing device for semi-dry desulfurization includes a desulfurization tower body 1. A discharge valve 2 is connected to the inner bottom wall of the desulfurization tower body 1. Two sets of fixing blocks 3 are connected to the inner wall of the desulfurization tower body 1. A fixing plate 4 is connected to one side of the two sets of fixing blocks 3 that are close to each other. A pressurization chamber 5 is opened inside the fixing plate 4. A set of spray heads 6 is opened on the bottom surface of the fixing plate 4. A desulfurizing agent holding tank 7 is connected to the outer surface of the desulfurization tower body 1. An injection port 8 is opened on the upper surface of the desulfurizing agent holding tank 7. A booster pump 9 is installed inside the desulfurizing agent holding tank 7. The output end of the booster pump 9 is connected to a conveying pipe 10. The output end of the conveying pipe 10 passes through the inner wall of the desulfurizing agent holding tank 7 and the inner wall of the desulfurization tower body 1, and is connected to the upper surface of the fixing plate 4. The outer surface of the desulfurization tower body 1 is connected to... A spiral tube 11 is provided, with a flue gas inlet 12 connected to the left side of the spiral tube 11. Two sets of sealed bearings 13 are embedded in the inner wall of the spiral tube 11, and connecting rods 14 are connected to the inner walls of both sets of sealed bearings 13. Guide plates 16 are connected to the outer surface of each connecting rod 14. A micro motor 15 is installed at the front end of one of the connecting rods 14. Connecting plates 17 are connected to the front and back of two of the guide plates 16. By cooperating with the booster pump 9 and the delivery pipe 10, the desulfurizing agent liquid inside the desulfurizing agent storage tank 7 can be transported to the inside of the booster chamber 5. This allows the spray head 6 to atomize the desulfurizing agent liquid using the pressure difference and spray it into the inside of the desulfurization tower body 1, so that the desulfurizing agent droplets come into contact with the flue gas, thereby performing desulfurization.

[0023] The front of the rotary cylinder 11 is connected to an arc-shaped seat 18, the upper surface of which is connected to the outer surface of the micro motor 15. The upper surface of the desulfurization tower body 1 is connected to a flue gas outlet 19, and a filter cotton 20 is connected inside the flue gas outlet 19. An observation window 21 is opened on the front of the desulfurization tower body 1, and a transparent glass is connected inside the observation window 21. The arc-shaped seat 18 can support the micro motor 15, which can make the micro motor 15 run more stably. The filter cotton 20 inside the flue gas outlet 19 can filter the particulate matter in the flue gas after desulfurization when it is discharged to the outside of the desulfurization tower body 1. The observation window 21 can facilitate the staff to observe the desulfurization status inside the desulfurization tower body 1.

[0024] Two reinforcing seats 22 are connected to the outer surface of the desulfurization tower body 1. The upper surfaces of the two reinforcing seats 22 are connected to the bottom surfaces of the desulfurizing agent holding box 7 and the bottom surfaces of the U-shaped cylinder 11, respectively. The desulfurization tower body 1 is connected by an annular plate 23. Two sets of support rods 24 are connected to the bottom surface of the annular plate 23. Each support rod 24 is connected to a mounting plate 25 at its bottom end. Each mounting plate 25 has a set of mounting holes 26 inside. The reinforcing seats 22 can be used to reinforce the desulfurizing agent holding box 7 and the U-shaped cylinder 11, so that the connection between the desulfurizing agent holding box 7 and the U-shaped cylinder 11 and the desulfurization tower body 1 is more secure. With the cooperation of the mounting plate 25 and the mounting holes 26, it is convenient for the staff to fix the desulfurization tower body 1 to the ground.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, the operator first connects the flue gas inlet 12 to the flue gas outlet of the external equipment, allowing the flue gas discharged from the external equipment to directly enter the interior of the desulfurization tower body 1. At this time, the operator uses the controller to start the booster pump 9. With the cooperation of the booster pump 9 and the delivery pipe 10, the desulfurizing agent liquid in the desulfurizing agent container 7 is delivered to the interior of the booster chamber 5. Then, the spray head 6 is used to spray the desulfurizing agent in the booster chamber 5 into desulfurizing agent droplets under pressure and spray them into the interior of the desulfurization tower body 1, so that the desulfurizing agent droplets come into contact with the flue gas inside the desulfurization tower body 1, thereby performing desulfurization on the flue gas. During the desulfurization operation, the operator uses the controller to start the micro motor 15. The micro motor 15 drives one of the connecting rods 14 and the guide plate 16 to rotate, and the two connecting plates 17 drive the other two guide plates 16 to rotate, thereby adjusting the direction of the flue gas entering the interior of the desulfurization tower body 1. The above is the complete operation process of this device.
