Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flue gas desulfurization, and in particular relates to a flue gas desulfurization device for a power plant. Background Art
[0002] A power plant converts some form of raw energy, such as water, steam, diesel, and gas, into electrical energy, and uses the generated electricity to supply fixed facilities or transportation power plants. A large amount of gas is generated in the power plant during the power generation process. In order to reduce the pollution of industrial waste smoke to the environment, the commonly used technology is to desulfurize the flue gas, so that the spray device inside the desulfurization tower sprays the desulfurization liquid to the waste smoke; when the waste smoke contacts the desulfurization liquid, the desulfurization liquid will react chemically with the waste smoke, thereby desulfurizing the waste smoke and then discharging it, thereby reducing pollution to the environment. Therefore, installing a spray device inside the desulfurization tower is an essential process;
[0003] In the prior art, when desulfurizing flue gas, in order to prevent particles in the exhaust smoke from being directly discharged into the air, the smoke is also filtered, but it is inconvenient to replace the filter device. Long-term use of the filter device without replacement will cause the filter device to be blocked and lose its filtering effect. Utility Model Content
[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a flue gas desulfurization device for a power plant, which is convenient for replacing the filter device, so as to solve the problems raised by the above background technology.
[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:
[0006] A flue gas desulfurization device for a power plant, comprising a desulfurization box, a smoke inlet and a smoke outlet, wherein the smoke inlet and the smoke outlet are respectively located at the input part and the output part of the desulfurization box, a spray assembly is assembled and connected in the input part of the desulfurization box, the spray assembly is connected to a water tank, and a filter assembly is assembled and connected in the output part of the desulfurization box;
[0007] The filter assembly includes a filter plate surrounded by a square frame, a sliding plate and two sliding rails. The two sliding rails are symmetrically arranged. The sliding plate is slidably connected to the sliding rails. The upper end of the filter plate is slidably connected to a makeshift groove opened on the upper side of the desulfurization box. Two positioning plates are fixedly connected to the lower side of the desulfurization box. The lower end of the filter plate is located between the two positioning plates. The lower side of the filter plate is slidably connected with an elastic member assembled and connected between the two positioning plates.
[0008] Preferably, a limiting plate for limiting the filter plate is fixedly connected to the upper side of the sliding plate.
[0009] Preferably, a T-shaped push block is provided above the sliding plate.
[0010] Preferably, on one side of the output part of the让位槽 above the desulfurization tank, there is a C-shaped strip. The lower side of the C-shaped strip is fixedly connected to the desulfurization tank, and one side of the sliding plate is located inside the C-shaped strip.
[0011] Preferably, the spray assembly includes a water spray pipe and a spray nozzle. The water spray pipe is located above the input part inside the desulfurization tank. The spray nozzle and the water spray pipe are assembled and connected, and the water spray pipe is communicated with the water tank.
[0012] Preferably, pillars are provided at the four feet on the lower side of the desulfurization tank.

[0016] The utility model can recycle the liquid generated by spraying, effectively saving the consumption of desulfurization liquid.
[0017] The structure of the utility model is ingenious. When the sliding plate is moved towards the input end of the desulfurization tank, the filter plate moves upward under the action of the elastic member, so that there is no need to manually take out the filter plate. The ingenious design of the limiting plate can prevent the filter plate from bouncing to a very high position when it pops up, limit the bouncing height of the filter plate, and release the elastic force of the elastic member.

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0029] like Figure 1-4 As shown, a flue gas desulfurization device for a power plant comprises a desulfurization box 1, a smoke inlet 11 and a smoke outlet 12, wherein the smoke inlet 11 and the smoke outlet 12 are respectively located at the input part and the output part of the desulfurization box 1, a spray assembly 13 is assembled and connected in the input part of the desulfurization box 1, and the spray assembly 13 is connected to a water tank 2, and a filter assembly 3 is assembled and connected in the output part of the desulfurization box 1;
[0030] The filter assembly 3 includes a filter plate 31 surrounded by a square frame, a sliding plate 32 and two sliding rails 33. The two sliding rails 33 are symmetrically arranged. The sliding plate 32 is slidably connected to the sliding rails 33. The upper end of the filter plate 31 is slidably connected to a makeshift groove opened on the upper side of the desulfurization box 1. Two positioning plates 34 are fixedly connected to the lower side of the desulfurization box 1. The lower end of the filter plate 31 is located between the two positioning plates 34. The lower side of the filter plate 31 is slidably connected to an elastic member 35 assembled and connected between the two positioning plates 34.
[0031] According to the technical solution of this embodiment, the flue gas that has been pre-treated and filtered enters the desulfurization box 1 from the smoke inlet 11, is discharged from the smoke outlet 12 after being processed by the desulfurization box 1, and the spray component 13 discharges the desulfurization liquid to react chemically with the flue gas. The water tank 2 is used to provide the desulfurization liquid to the spray component 13. The filter component 3 is used to filter the flue gas and filter large particles in the flue gas. The filter plate 31 slides horizontally in the slide rail 33. The upper end of the filter plate 31 is located outside the desulfurization box 1. The sliding plate 32 slides above the filter plate 31. When the sliding plate 32 is taken out, the filter plate 31 pops out under the action of the elastic member 35. There is no need to manually take out the filter plate 31. The filter plate 31 can be taken out, which is convenient for replacing the filter plate 31.
[0032] Reference Figure 5 A limiting plate 321 for limiting the filter plate 31 is fixedly connected to the upper side of the sliding plate 32.
[0033] In this embodiment, the limiting plate 321 is used to limit the filtered plate 31 after it pops out, preventing the filtered plate 31 from popping out directly under the action of the elastic member 35. Slide the sliding plate 32 along the slide rail 33. After the sliding plate 32 separates from the filtered plate 31, the filtered plate 31 pops out under the action of the elastic member 35. After popping out, it first contacts the limiting plate 321, and the limiting plate 321 limits the filtered plate 31.
[0034] Refer to Figure 5 : A T-shaped push block 322 is provided above the sliding plate 32.
[0035] In this embodiment, the T-shaped push block 322 is used to facilitate the operator to move the sliding plate 32.
[0036] Refer to Figure 2-3 : On one side of the output part of the让位槽 (letting-position groove) above the desulfurization tank 1, there is an inverted U-shaped strip 36. The lower side of the inverted U-shaped strip 36 is fixedly connected to the desulfurization tank 1, and one side of the sliding plate 32 is located inside the inverted U-shaped strip 36.
[0037] In this embodiment, the inverted U-shaped strip 36 is used to position the sliding plate 32, preventing one side of the sliding plate 32 from deforming under the action of the filtered plate 31.
[0038] Refer to Figure 2-3 : The spray assembly 13 includes a water spray pipe 131 and a spray nozzle 132. The water spray pipe 131 is located above the input part inside the desulfurization tank 1. The spray nozzle 132 and the water spray pipe 131 are assembled and connected, and the water spray pipe 131 is communicated with the water tank 2.
[0039] In this embodiment, the spray nozzle 132 is used to discharge the desulfurization liquid spray to treat the flue gas. A water pump is connected to the water spray pipe 131 inside the water tank 2, and the water pump supplies the desulfurization liquid to the water spray pipe 131.
[0040] Refer to Figure 1 : Four feet at the lower side of the desulfurization tank 1 are all provided with support columns 101. The bottom surface of the water tank 2 is flush with the lower side of the support columns 101. A water pipe 21 is communicated between the bottom of the input side of the desulfurization tank 1 and the water tank 2.
[0041] In this embodiment, the water pipe 21 is used to collect the liquid at the bottom of the desulfurization tank 1.
[0042] Refer to Figure 4 : A chamfer is provided on one side of the input part above the filtered plate 31.
[0043] In this embodiment, the chamfer of the filter plate 31 is used to facilitate the sliding plate 32 to limit the filter plate 31. When the filter plate 31 is taken out and then installed, when the sliding plate 32 slides to one side of the filter plate 31, the sliding plate 32 first contacts the chamfer of the filter plate 31, thereby reducing the resistance encountered when moving the sliding plate 32.
[0044] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
[0045] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
