Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example

[0027] Please see Figures 1-5 This utility model provides a high-efficiency washing device for gasification slag hydration syngas, including a tower body 100 and a slag cleaning and circulation mechanism 200.

[0028] The slag cleaning and circulation mechanism 200 is installed inside the tower body 100. Through the slag cleaning and circulation mechanism 200, the washing liquid can be filtered and recovered for recycling, reducing the possibility that the washing device will consume a large amount of washing liquid during operation.

[0029] Please see Figures 1-3The tower body 100 has an inlet pipe 110 and an outlet pipe 120 connected to its surface. A connecting pipe 130 is slidably installed at the bottom of the tower body 100. A liquid storage tank 140 is connected to the lower end of the connecting pipe 130. A water pump 150 is connected to the top of the liquid storage tank 140. The input end of the water pump 150 is connected to the liquid storage tank 140, and the output end of the water pump 150 is connected to a spray nozzle 170 via a telescopic pipe 160. A filter plate 180 is connected inside the tower body 100. In practical implementation, the gas is supplied through external gas transmission equipment. The syngas from the gasification slag is transported to the tower body 100 through the inlet pipe 110. Particulate impurities in the syngas are filtered by the filter plate 180. By starting the water pump 150, the washing liquid in the storage tank 140 is transported to the spraying device 170 through the telescopic pipe 160. The spraying device 170 sprays the washing liquid into the tower body 100, which can wash the syngas from the gasification slag. The washing liquid falls from the connecting pipe 130 into the storage tank 140, which is conducive to the recycling of the washing liquid.

[0030] In this embodiment, a hydraulic cylinder 141 is installed on the top of the storage tank 140. Several hydraulic cylinders 141 are provided, and a connecting block 142 is connected to the movable end of each hydraulic cylinder 141. The connecting block 142 is fixedly connected to the bottom of the tower body 100. In specific implementation, when it is necessary to remove the slag collection dish 240 and the activated carbon filter plate 250, the hydraulic cylinder 141 is activated, causing its movable end to move the connecting block 142 and the tower body 100 upwards. The tower body 100 will then separate from the connecting pipe 130, and the cleaning component 230 will no longer be located inside the slag collection dish 240. At this time... The slag collection dish 240 and activated carbon filter plate 250 can be removed from the connecting pipe 130 for easy cleaning or replacement. The output end of the water pump 150 is connected to one end of the telescopic pipe 160 through the pipe body. The other end of the telescopic pipe 160 is connected to the liquid delivery pipe 161, which is connected to the spraying component 170. In specific implementation, when the movable end of the hydraulic cylinder 141 drives the tower body 100 to move upward, the telescopic pipe 160 will be stretched, reducing the possibility of damage to the pipeline conveying the washing liquid.

[0031] The spraying component 170 includes an annular pipe 171 and a nozzle 172. The annular pipe 171 is connected to the tower body 100 through a support rod 173, and the annular pipe 171 is connected to the nozzle 172 and the infusion pipe 161. Several nozzles 172 are provided.

[0032] Please see Figures 1-5The slag cleaning and circulation mechanism 200 includes a motor 210 and a connecting shaft 220. The motor 210 is mounted on the surface of the tower body 100, and the output shaft of the motor 210 is connected to the connecting shaft 220 for transmission. The connecting shaft 220 is rotatably connected inside the tower body 100, and a cleaning component 230 is connected to the lower end of the connecting shaft 220. A slag collection dish 240 and an activated carbon filter plate 250 are slidably arranged inside the connecting pipe 130. The cleaning component 230 is attached to the bottom wall of the slag collection dish 240. A through hole 260 is opened inside the slag collection dish 240. In specific implementation, when the washing liquid is sprayed into the tower body 100, the washing liquid will pass through the filter plate 180 and enter the connecting pipe 130. The slag on the filter plate 180 is cleaned and discharged. The separated particulate impurities will fall into the slag collection dish 240 of the connecting pipe 130. The particulate impurities will accumulate in the slag collection dish 240. The cleaning element 230 rotates in the slag collection dish 240, which can reduce the possibility of particulate impurities clogging the through hole 260. The diameter of the through hole 260 is smaller than the volume of the particulate impurities. The washing liquid will fall from the through hole 260 to the activated carbon filter plate 250. The activated carbon filter plate 250 can adsorb harmful substances in the washing liquid. The filtered and purified washing liquid will fall into the storage tank 140, which is conducive to the filtration and recycling of the washing liquid and reduces the possibility of the washing device consuming a large amount of washing liquid during operation.

[0033] In this embodiment, the output shaft of the motor 210 is connected to a first bevel gear 211, and the surface of the connecting shaft 220 is connected to a second bevel gear 221. The first bevel gear 211 and the second bevel gear 221 are meshed together. A support shell 190 is connected inside the tower body 100, and the connecting shaft 220 is rotatably connected inside the support shell 190. The first bevel gear 211 and the second bevel gear 221 are both located inside the support shell 190. In specific implementation, the support shell 190 can support the connecting shaft 220. By placing the first bevel gear 211 and the second bevel gear 221 inside the support shell 190, the possibility of wear caused by long-term contact between the first bevel gear 211 and the second bevel gear 221 and the washing liquid and synthesis gas is reduced.

[0034] A connecting plate 270 is connected to the upper end of the connecting shaft 220. A cleaning brush 271 is connected to the upper surface of the connecting plate 270. The cleaning brush 271 is in contact with the lower surface of the filter plate 180. In specific implementation, when the output shaft of the motor 210 drives the connecting shaft 220 to rotate, the connecting plate 270 can be rotated. The cleaning brush 271 will rotate along the lower surface of the filter plate 180, which is conducive to cleaning the particulate impurities adhering to the lower surface of the filter plate 180 and reducing the possibility that particulate impurities will clog the filter pores on the surface of the filter plate 180. A sealing ring 131 is connected to the upper surface of the connecting pipe 130. The sealing ring 131 is in contact with the bottom of the tower body 100.

[0035] The cleaning component 230 includes a cleaning plate 231 and a cleaning brush 232. The cleaning plate 231 is fixedly connected to the connecting shaft 220 and the cleaning brush 232. The cleaning brush 232 is in contact with the bottom wall of the slag collection dish 240. An arc-shaped plate 241 is connected to the surface of the slag collection dish 240. The arc-shaped plate 241 is connected to the activated carbon filter plate 250, and a handle is connected to the surface of the arc-shaped plate 241. A sealing gasket 242 is connected at the connection between the connecting pipe 130 and the arc-shaped plate 241. In practice, by pulling the handle, the arc-shaped plate 241 can be opened. The curved plate 241 is removed from the connecting pipe 130, thereby removing the slag collection dish 240 and the activated carbon filter plate 250 from the connecting pipe 130, making it easier to clean or replace the slag collection dish 240 and the activated carbon filter plate 250. A sealing gasket 242 is provided between the connecting pipe 130 and the curved plate 241 to reduce the possibility of washing liquid overflowing from the gap between the connecting pipe 130 and the curved plate 241. It should be noted that the sealing gasket 242 and the sealing ring 131 are made of rubber or silicone.

[0036] Specifically, the working principle of this high-efficiency washing device for gasified slag-water syngas is as follows: During operation, the gasified slag-water syngas is transported from the inlet pipe 110 to the tower body 100. The filter plate 180 filters particulate impurities in the syngas. By starting the water pump 150, the washing liquid in the storage tank 140 is transported from the telescopic pipe 160 to the annular pipe 171. The washing liquid is then sprayed into the tower body 100 from the nozzle 172, facilitating the washing of the syngas. The treated syngas is discharged from the outlet pipe 120. By starting the motor 210, its output shaft drives the first bevel gear 211, the second bevel gear 221, and the connecting shaft 220 to rotate. The cleaning brush 271 cleans the particulate impurities adhering to the lower surface of the filter plate 180, and the particulate impurities fall into the slag collection dish 24. Within the 0, the cleaning brush 232 cleans particulate impurities from the slag collection dish 240. The washing liquid falls from the through hole 260 of the slag collection dish 240 onto the activated carbon filter plate 250. The activated carbon filter plate 250 adsorbs harmful substances in the washing liquid. The treated washing liquid falls into the storage tank 140, which can be filtered and recycled, reducing the possibility of the washing device consuming a large amount of washing liquid during operation. By activating the hydraulic cylinder 141, its movable end drives the tower body 100 upward, and the connecting pipe 130 moves away from the tower body 100. The cleaning plate 231 is no longer located in the slag collection dish 240, and the slag collection dish 240 and the activated carbon filter plate 250 can be removed from the connecting pipe 130 for easy replacement.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
