[0002] Gas pretreatment refers to a systematic process of removing impurities, adjusting composition, and stabilizing parameters of gas through physical, chemical, or biological means before it enters end-use equipment. Pretreatment is a core prerequisite for the efficient, stable, and environmentally friendly operation of gas generator sets.

[0003] In existing technologies, solid particles in coal gas are typically filtered through a filter screen during coal gas pretreatment to remove impurities. However, different coal gas generator sets have different requirements for coal gas purity, and the existing technology cannot adjust the filter specifications, resulting in a limited range of applicability.

A first fixed plate is fixed in the inner cavity of the processing box. A plurality of first filter frames are fixed on the first fixed plate.

[0018] 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.

[0019] Reference Figures 1-4This utility model provides a technical solution: a gas pretreatment device for a gas generator set, including a treatment box 1. The treatment box 1 has a gas pretreatment mechanism inside, which includes a first fixed plate 201 and a first rotating rod 204. The first fixed plate 201 is detachably fixed to the inner cavity of the treatment box 1 by bolts and a mounting plate. A plurality of first filter frames 202 are fixedly mounted on the first fixed plate 201, and a plurality of second filter frames 203 are rotatably mounted on the first fixed plate 201. The number of first filter frames 202 is the same as the number of second filter frames 203. Each first filter frame 202 and second filter frame 203... The filter frames 203 are arranged in a group adjacent to each other. In this embodiment, there are two first filter frames 202 and two second filter frames 203. The first rotating rod 204 is rotatably disposed between the first filter frames 202 and the second filter frames 203. Several scrapers 205 are fixed on the surface of the first rotating rod 204. The scrapers 205 are in contact with the second filter frames 203. Several maintenance doors are sealed on the treatment box 1. An air inlet is provided on the left side of the treatment box 1, and an air outlet is provided on the right side. Coal gas is introduced through the air inlet, and the pre-treated coal gas is extracted from the air outlet through a suction pump. The number of first fixed plates 201 is set to two. To improve filtration efficiency, the filter holes of the first filter frame 202 and the second filter frame 203 on the left first fixed plate 201 are larger than those on the right first fixed plate 201. This allows for coarse filtration of the gas followed by fine filtration. The filter holes of the first filter frame 202 and the second filter frame 203 overlap and are coaxially arranged. By incorporating a gas pretreatment mechanism, as the second filter frame 203 rotates, the filter holes of the first filter frame 202 and the second filter frame 203 gradually intersect, thus reducing the area between the two filter holes. This allows users to adjust the filter specifications as needed. When the second filter hole needs cleaning, the filter holes between the first filter frame 202 and the second filter frame 203 can be completely staggered, so that the filter holes on the second filter frame 203 are blocked by the first filter frame 202. At this time, the first rotating rod 204 is driven to rotate, thereby driving the scraper 205 to rotate. The scraper 205 scrapes off the solid particles in the gas intercepted by the second filter frame 203. The solid particles cannot pass through the second filter frame 203 and will only fall to the side of the second filter frame 203 away from the first filter frame 202, which is convenient for users to clean later. Reference Figures 1-4A first maintenance chamber 206 is fixedly provided on the side of the first filter frame 202 away from the second filter frame 203. A first bevel gear 207 is rotatably provided on the inner wall of the first maintenance chamber 206. A second bevel gear 208 is coaxially fixed on the surface of the first rotating rod 204. The first bevel gear 207 and the second bevel gear 208 mesh with each other. A first connecting rod 209 is rotatably provided on the inner top wall of the treatment box 1. Several first bevel gears 207 are coaxially fixed on the surface of the first connecting rod 209. A first motor 210 is fixedly provided on the top of the treatment box 1 by bolts and mounting plates. The output end of the first motor 210 is fixedly connected to the first connecting rod 209 by a coupling. By setting the first bevel gear 207 and the second bevel gear 208, the first motor 210 is started, which drives the first connecting rod 209 to rotate. The first connecting rod 209 drives several first bevel gears 207 to rotate simultaneously. Through the meshing connection of the first bevel gear 207 and the second bevel gear 208, the second bevel gear 208 drives the first rotating rod 204 to rotate. Reference Figures 1-4 The surface of the second filter frame 203 is coaxially fixed with a gear ring 211. Two drive gears 212 are rotatably arranged inside the first fixed plate 201. The gear ring 211 and the drive gears 212 mesh. A number of drive gears 212 are coaxially fixed with transmission rods inside. A number of transmission rods are coaxially fixed with rotating wheels on their surfaces. A transmission belt is sleeved between the transmission rods via the rotating wheels. The transmission belt includes necessary components such as a tensioning wheel. In other embodiments, when the number of first filter frames 202 and second filter frames 203 is greater than two, sprockets and chains are used to replace the rotating wheels and transmission belts. A drive rod is fixed between one of the transmission rods on the left first fixed plate 201 and one of the transmission rods on the right first fixed plate 201. The first fixed plate 20... A protective shell is fixed to the right side of 1 by bolts. The transmission belt and the pulley are both wrapped inside the protective shell. A second motor is fixed to the right side of the protective shell by bolts and a mounting plate. The output end of the second motor is fixedly connected to one of the transmission rods through a coupling. By setting a gear ring 211, the second motor is started, which drives one of the transmission rods to rotate, causing one of the drive gears 212 to rotate. Through the meshing connection between the drive gear 212 and the gear ring 211, the gear ring 211 drives the second filter frame 203 to rotate. At the same time, through the cooperation of the transmission belt, the second filter frames 203 on the same first fixed plate 201 rotate simultaneously. Through the cooperation of the drive rod, the second filter frames 203 on the two first fixed plates 201 rotate simultaneously. Reference Figures 1-4The treatment box 1 is equipped with a desulfurization mechanism, which includes a second fixing plate 301. The second fixing plate 301 is detachably fixed to the inner cavity of the treatment box 1 by bolts and mounting plates. Several purification frames 302 are installed on the second fixing plate 301. Desulfurization catalyst particles are arranged inside the purification frames 302. In this embodiment, there are two purification frames 302. The second fixing plate 301 is located between two first fixing plates 201. A second rotating rod 303 is coaxially rotatably arranged inside the purification frame 302. A stirring blade 304 is fixed on the second rotating rod 303. By setting up the desulfurization mechanism, when the gas passes through the inside of the purification frame 302, the gas comes into contact with the desulfurization catalyst particles, so that the gas undergoes desulfurization treatment. At the same time, the second rotating rod 303 is driven to rotate, so that the stirring blade 304 rotates. The stirring blade 304 agitates the desulfurization catalyst particles, thereby increasing the contact area between the desulfurization catalyst particles and the gas and improving the desulfurization effect. Reference Figures 1-4 A second maintenance compartment 305 is fixedly installed on the right side of the purification frame 302. A third bevel gear 306 is rotatably mounted on the inner wall of the second maintenance compartment 305. One side of the second rotating rod 303 extends into the interior of the second maintenance compartment 305. A fourth bevel gear 307 is coaxially fixed on the surface of the end of the second rotating rod 303 that extends into the interior of the second maintenance compartment 305. The third bevel gear 306 and the fourth bevel gear 307 mesh with each other. A second connecting rod 308 is rotatably mounted on the inner top wall of the treatment box 1. Several third bevel gears 306 are coaxially fixed on the second connecting rod 308. On the surface of 8, the top of the processing box 1 is fixed with a third motor 309 by bolts and mounting plate. The output end of the third motor 309 is fixedly connected to the second connecting rod 308 by a coupling. By setting a third bevel gear 306 and a fourth bevel gear 307, the third motor 309 is started, which drives the second connecting rod 308 to rotate. The second connecting rod 308 simultaneously drives several third bevel gears 306 to rotate. Through the meshing connection of the third bevel gear 306 and the fourth bevel gear 307, the fourth bevel gear 307 drives the second rotating rod 303 to rotate.

[0020] Specifically, the working process or principle of the gas pretreatment device for the gas generator set is as follows: During use, the third motor 309 is started, driving the second connecting rod 308 to rotate. Simultaneously, the second connecting rod 308 drives several third bevel gears 306 to rotate. Through the meshing connection between the third bevel gears 306 and the fourth bevel gear 307, the fourth bevel gear 307 drives the second rotating rod 303 and the stirring blade 304 to rotate, introducing gas through the inlet. The pretreated gas is then extracted from the outlet by a suction pump. During this process, the gas… First, the gas undergoes coarse filtration through the first fixed plate 201 on the left, then passes through the purification frame 302, where the gas comes into contact with the desulfurization catalyst particles, thus desulfurizing the gas. Simultaneously, the stirring blades 304 agitate the desulfurization catalyst particles, increasing the contact area between the particles and the gas. Next, the gas undergoes fine filtration through the first fixed plate 201 on the right. When the filtration specifications need adjustment, the second motor is activated, driving one of the transmission rods to rotate, causing one of the drive gears 212 to rotate. Through the meshing of the drive gear 212 and the gear ring 211... The gear ring 211 drives the second filter frame 203 to rotate, and the transmission belt causes the second filter frames 203 on the same first fixed plate 201 to rotate simultaneously. The drive rod causes the second filter frames 203 on both first fixed plates 201 to rotate simultaneously, thus reducing the area between the two filter holes. When cleaning the second filter frame 203 is required, the filter holes between the first filter frame 202 and the second filter frame 203 are completely interleaved, causing the filter holes on the second filter frame 203 to be blocked by the first filter frame 202. The first motor 210 is activated, which drives the first connecting rod 209 to rotate. The first connecting rod 209 drives several first bevel gears 207 to rotate simultaneously. Through the meshing connection of the first bevel gears 207 and the second bevel gears 208, the second bevel gears 208 drive the first rotating rod 204 to rotate, thereby driving the scraper 205 to rotate. The scraper 205 scrapes away the solid particles in the gas intercepted by the second filter frame 203. The solid particles cannot pass through the second filter frame 203 and will only fall to the side of the second filter frame 203 away from the first filter frame 202.
