Description

Technical Field

[0001] This invention relates to the field of pulse dust removal, and more specifically, to a pulse-controlled gas blowing device. Background Technology

[0002] The pulse-controlled gas cleaning device is the core cleaning system of industrial dust removal equipment and a key supporting equipment for solid waste pollution prevention and control. Its core function is to use instantaneous high-pressure pulse airflow to reverse-blow the filter bags, remove the dust and solid waste accumulated on the surface of the filter bags, restore the normal flue gas filtration capacity of the filter bags in a timely manner, and ensure the continuous and stable operation of the dust removal equipment.

[0003] For example, the Chinese invention patent (application number: 201310504158.8) discloses a "pulse jet cleaning device for a bag filter," the description of which states: It includes a gas storage tank shell, a gas distribution tank shell, gas storage tank end caps welded to both ends of the gas storage tank shell, gas distribution tank end caps welded to both ends of the gas distribution tank shell, a flat partition between the gas storage tank shell and the gas distribution tank shell, and a partition inside the gas distribution tank shell; the gas storage tank shell, the flat partition, and the gas storage tank end caps form a gas storage tank space; a pulse valve and an equal number of exhaust pipes are installed on the gas storage tank shell, one end of the exhaust pipe is connected to the pulse valve, and the other end is welded to the flat partition; utilizing the flat partition, A partition plate, a gas distribution box shell, and a gas distribution box end cap form a gas distribution box space. An exhaust pipe connects the gas storage box space and the gas distribution box space. A hole is made in the gas distribution box shell of each formed gas distribution box space, a gas distribution pipe is installed, a blow pipe is inserted into the gas distribution pipe, and a nozzle is configured on the blow pipe. An air inlet pipe is provided on the gas storage box shell.

[0004] However, the aforementioned pulse jet cleaning device for bag filters has some shortcomings in actual use: In the prior art, the nozzles are arranged linearly on the jet pipe. Since the jet pipe is single-ended, the air output and jet speed of each nozzle decrease gradually along the air intake direction. The nozzles at the near end spray strongly and the nozzles at the far end spray weakly. This leads to uneven overall jet cleaning effect. The nozzles at the near end are prone to over-scouring due to the strong air, while the nozzles at the far end cannot be effectively cleaned due to the weak air. This results in uneven cleaning of the filter bags, local dust accumulation and blockage, and a decrease in the equipment's filtration efficiency.

[0005] Therefore, we made improvements and proposed a pulse-controlled gas blowing device. Summary of the Invention

[0006] The purpose of this invention is to address the problem that existing pulse-controlled gas cleaning devices suffer from uneven blowing effects and reduced equipment filtration efficiency due to the single-end air intake of the blowing pipe, linear arrangement of nozzles, and progressively decreasing air output and injection speed of each nozzle along the air intake direction.

[0007] To achieve the above-mentioned objectives, the present invention provides a pulse-controlled gas blowing device to improve the aforementioned problems.

[0019] As a preferred technical solution of this application, the guide rod is slidably disposed on the housing, the deviation ring and the correction ring are both adapted to the nozzle, and the deviation ring and the correction ring are slidably disposed on the outer wall of the blow pipe.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In the scheme of this application:

[0022] 1. In order to solve the problem that the pulse-controlled gas cleaning device in the prior art has uneven cleaning effect due to the single-end air inlet of the blow pipe and the linear arrangement of the nozzles, resulting in a gradual decrease in the air output and jet speed of each nozzle along the air inlet direction, which leads to a decrease in the cleaning effect and a decrease in the filtration efficiency of the equipment, this application sets up a synchronous adjustment mechanism. The synchronous adjustment mechanism drives multiple nozzles to clean the filter bag synchronously, and the gradual groove reduces the gradual decrease in the air output and jet speed of the nozzles, thereby reducing the uneven cleaning caused by sequential blowing and improving the filtration efficiency of the equipment.

[0023] 2. By setting a synchronous adjustment mechanism, the nozzle is driven to rotate and spray, avoiding long-term concentrated airflow to scour local areas of the filter bag, reducing the occurrence of scouring blind spots in fixed nozzles, reducing local wear and damage to the filter bag, improving the service life of the filter bag, and solving the problem of reduced service life caused by long-term local scouring of the filter bag in the prior art;

[0024] 3. Through the set synchronous adjustment mechanism, the nozzle is driven to gradually weaken the pulse jet. At the beginning of the pulse, the filter bag is back-blown by high-pressure gas. After the pulse ends, the low-pressure gas is sprayed downwards by the compression of the space above the cavity to assist in the settling, reduce the secondary adsorption of dust on the filter screen, improve the dust removal efficiency, and solve the problem of low dust removal efficiency caused by secondary dust re-entrainment in the existing technology.

[0025] 4. By setting a synchronous adjustment mechanism, the rubber tube is driven to flexibly impact the box, causing the equipment to vibrate. This reduces dust adhesion and blockage at the nozzle output end, improves the stability of the nozzle's airflow, and solves the problem of unstable airflow caused by dust adhesion at the nozzle output end in the existing technology.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0038] As described in the background art, the pulse-controlled gas cleaning device has uneven blowing effect due to the single-end air intake of the blowing pipe and the linear arrangement of the nozzles. The air output and injection speed of each nozzle decrease step by step along the air intake direction, resulting in a reduction in the equipment's filtration efficiency.

[0039] To solve this technical problem, the present invention provides a pulse-controlled gas blowing device, which is applied to pulse dust removal.

[0040] For details, please refer to Figure 1 - Figure 8 As shown, the pulse-controlled gas purging device specifically includes: a housing 1, a pulse valve 101 disposed on the housing 1, and a synchronous adjustment mechanism 2 disposed on the housing 1. In the prior art, the pulse valve 101 is used to switch on and off the high-pressure gas path.

[0041] The synchronous adjustment mechanism 2 includes a cavity 201 disposed in the housing 1, a blow pipe 202 disposed on the housing 1, a nozzle 203 disposed on the blow pipe 202, a jacking pipe 204 slidably disposed on the housing 1, a gradient groove 205 disposed in the jacking pipe 204, a connecting groove 206 disposed on the jacking pipe 204, a rectangular plate 207 slidably disposed in the cavity 201, and a spring 208 disposed on the rectangular plate 207.

[0042] The pulse-controlled gas cleaning device provided by this invention addresses the problem in the prior art where the pulse-controlled gas cleaning device has a single-end air intake of the blowpipe 202 and linear arrangement of nozzles 203, resulting in a gradual decrease in the air output and jet speed of each nozzle 203 along the air intake direction, leading to uneven cleaning effect and reduced equipment filtration efficiency. This application provides a synchronous adjustment mechanism 2, which drives multiple nozzles 203 to clean the filter bag synchronously. The gradient groove 205 reduces the gradual decrease in the air output and jet speed of the nozzles 203, thereby reducing uneven cleaning caused by sequential blowing and improving the equipment filtration efficiency.

[0043] By using the synchronous adjustment mechanism 2, the nozzle 203 is driven to rotate and spray, avoiding long-term concentrated airflow scouring of local areas of the filter bag, reducing the occurrence of scouring blind spots in the fixed nozzle 203, reducing local wear and damage to the filter bag, improving the service life of the filter bag, and solving the problem of reduced service life caused by long-term local scouring of the filter bag in the prior art.

[0044] The synchronous adjustment mechanism 2 drives the nozzle 203 to gradually weaken the pulse jet. When the pulse starts, the filter bag is back-blown by high-pressure gas. After the pulse ends, the low-pressure gas is sprayed downwards by the compression of the space above the cavity 201 to assist in settling, reduce the secondary adsorption of dust on the filter screen, improve the dust removal efficiency, and solve the problem of low dust removal efficiency caused by secondary dust re-entrainment in the existing technology.

[0045] By using the synchronous adjustment mechanism 2, the rubber tube 211 is driven to flexibly impact the housing 1, causing the device to vibrate. This reduces dust adhesion and blockage at the output end of the nozzle 203, improves the stability of the airflow from the nozzle 203, and solves the problem of unstable airflow caused by dust adhesion at the output end of the nozzle 203 in the prior art.

[0046] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0049] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the pulse-controlled gas cleaning device has a jacking tube 204 slidably disposed on the inner wall of the spray pipe 202. The gradient groove 205, the connecting groove 206 and the cavity 201 are all interconnected. The connecting groove 206 and the nozzle 203 are mutually adapted. The rectangular plate 207 is disposed above the jacking tube 204.

[0050] Pulse valve 101 is connected to cavity 201. During use, pulse valve 101 opens, allowing high-pressure gas to enter cavity 201. The high-pressure gas then enters gradient groove 205 from cavity 201, pushing the bottom of actuating tube 204 downwards. Simultaneously, rectangular plate 207 slides downwards along cavity 201, compressing spring 208. This compression guides actuating tube 204. Figure 7 As shown, the space of the gradient groove 205 within the jacking tube 204 gradually decreases from the inlet end, reducing the pressure loss when the high-pressure gas reaches the bottom of the jacking tube 204. Figure 3As shown, the initial state of the jacking tube 204 blocks the nozzle 203. The jacking tube 204 slides downwards and releases the blockage of the nozzle 203. Simultaneously, the connecting groove 206 slides downwards and connects with the nozzle 203. At this time, high-pressure gas is simultaneously ejected from multiple nozzles 203, allowing the filter bag to receive synchronized cleaning impact at the same time. This avoids uneven cleaning caused by sequential blowing. The gradient groove 205 reduces the gradual decrease in air output and spray speed of the nozzle 203, improving the filtration efficiency of the equipment. When the filter bag cleaning is finished, the elasticity of the spring 208 drives the rectangular plate 2... 07 and the top-moving tube 204 slide and reset synchronously. The rectangular plate 207 and the cavity 201 are seamlessly connected. When the rectangular plate 207 slides and resets upward, the space above the rectangular plate 207 and the cavity 201 is compressed, so that the nozzle 203 continues to spray gas before being blocked by the top-moving tube 204. This method realizes the gradually weakening pulse. At the beginning of the pulse, the filter bag is back-blown by high-pressure gas. After the pulse ends, the low-pressure gas sprayed out is used to assist in the settling by the compression of the space above the cavity 201, which reduces the secondary adsorption of dust on the filter screen and improves the dust removal efficiency.

[0051] Furthermore, the blow pipe 202 is rotatably mounted on the housing 1, the push pipe 204 is rotatably mounted with a ball bearing 209, and the blow pipe 202 is provided with a spiral groove 210, with the ball bearing 209 and the spiral groove 210 being mutually compatible.

[0052] When the jacking tube 204 slides downward, the ball bearings 209 on the jacking tube 204 squeeze the spiral groove 210 and drive the blow pipe 202 to rotate. The connecting groove 206 slides downward synchronously and connects with the nozzle 203. The nozzle 203 on the blow pipe 202 rotates synchronously. At this time, high-pressure gas is ejected from the nozzle 203. The filter bag is blown away by the rotation of the nozzle 203. The rotation of the nozzle 203 can make the airflow cover the entire circumference and height of the filter bag, reduce the situation of the fixed nozzle 203 having a blind spot for scouring, and improve the comprehensiveness of cleaning. The use of rotating blow can avoid the long-term concentrated scouring of the local area of ​​the filter bag by the airflow, reduce the local wear and damage of the filter bag, and improve the service life of the filter bag.

[0053] Furthermore, a rubber tube 211 is provided on the jacking tube 204, and the rubber tube 211 and the housing 1 are mutually compatible.

[0054] When the jacking tube 204 and the rectangular plate 207 slide down synchronously, the rubber tube 211 on the jacking tube 204 slides down synchronously. When the rubber tube 211 hits the bottom of the box 1, the device vibrates through the flexible impact, which reduces dust adhesion and blockage of the nozzle 203 output end, improves the stability of the airflow of the nozzle 203, and improves the dust removal effect.

[0055] Furthermore, a sliding groove 212 is provided inside the housing 1, and an adjusting block 213 is provided on the sliding groove 212. The two ends of the spring 208 are respectively provided on the corresponding surfaces of the adjusting block 213 and the rectangular plate 207. A threaded rod 214 is rotatably provided on the housing 1. The adjusting block 213 is threadedly connected to the threaded rod 214. A knob 215 is provided on the threaded rod 214. A limit plate 223 is provided inside the cavity 201.

[0056] By rotating knob 215, the knob 215 drives threaded rod 214 to rotate, and threaded rod 214 rotates and drives adjusting block 213 to slide along sliding groove 212. Rectangular plate 207 is limited by limiting plate 223. Adjusting block 213 slides and squeezes spring 208, causing spring 208 to compress, thereby adjusting the elasticity of spring 208. By adjusting the elasticity of spring 208 in this way, the elasticity of spring 208 can be adjusted according to the high-pressure gas ejected by pulse valve 101, so that the elastic force of spring 208 is dynamically matched with pulse gas pressure, improving the practicality of equipment.

[0057] Furthermore, a wedge block 216 is provided on the housing 1, and a wedge block 217 is provided on the rubber tube 211. The wedge block 217 is slidably disposed on the surface of the wedge block 216.

[0058] Furthermore, both wedge block 1 216 and wedge block 2 217 are made of rubber, and wedge block 1 216 and wedge block 2 217 are compatible with each other;

[0059] When the jacking tube 204 slides upward to reset, the wedge block 217 and the jacking tube 204 slide upward synchronously, as follows: Figure 3 As shown, both wedge block 216 and wedge block 217 have wedge-shaped cross sections. When wedge block 217 slides upward, it slides and rubs against wedge block 216 and deforms. The deformation of wedge block 216 and wedge block 217 increases the friction force of wedge block 217 sliding upward, slowing down the sliding speed of rectangular plate 207 returning to its original position. This slows down the compression of the space above the cavity 201 by rectangular plate 207. In this way, the residual gas in the cavity 201 and the gradient groove 205 is discharged, and the residual gas in the pipeline is pre-emptied, so that the pressure of each pulse is stable and the stability of the equipment is improved.

[0060] The synchronous adjustment mechanism 2 drives multiple nozzles 203 to simultaneously clean the filter bag. The gradient groove 205 reduces the gradual decrease in air output and spray speed of the nozzles 203, thus reducing uneven cleaning caused by sequential spraying and improving the filtration efficiency of the equipment. The synchronous adjustment mechanism 2 also drives the nozzles 203 to rotate and spray, reducing blind spots caused by fixed nozzles 203 and improving the comprehensiveness of cleaning. The synchronous adjustment mechanism 2 also drives the nozzles 203 to rotate and spray, avoiding long-term concentrated airflow to scour local areas of the filter bag, reducing local wear and damage, and improving the service life of the filter bag. The synchronous adjustment mechanism 2 drives the rubber tube 211 to flexibly impact the housing 1, causing the equipment to vibrate, reducing dust adhesion and clogging of the nozzles 203 output ends, improving the stability of the airflow from the nozzles 203, and improving the cleaning effect. The synchronous adjustment mechanism 2 also pre-empties the residual air in the pipeline, ensuring stable pressure for each pulse and improving the stability of the equipment.

[0061] Example 2 further optimizes the pulse-controlled gas purging device provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a drive disk 218 is rotatably mounted on the blow pipe 202, a drive hole 219 is provided on the drive disk 218, and a nozzle 203 is mounted on the drive disk 218. The drive hole 219 and the nozzle 203 are connected to each other.

[0062] like Figure 8 As shown, by rotating the nozzle 203, the nozzle 203 and the drive disk 218 rotate synchronously, and the spray angle of the nozzle 203 can be adjusted in this way;

[0063] Furthermore, a guide rod 220 is provided on the rectangular plate 207, and a deviation ring 221 and a correction ring 222 are provided on the guide rod 220;

[0064] Furthermore, the guide rod 220 is slidably mounted on the housing 1, and both the offset ring 221 and the correction ring 222 are adapted to the nozzle 203, such as... Figure 3 As shown, in the initial state, the correction ring 222 and the nozzle 203 are in contact, so that the nozzle 203 is in a vertical state. When the deviation ring 221 and the correction ring 222 slide downward synchronously, the correction ring 222 disengages from the nozzle 203, the deviation ring 221 slides downward and squeezes the nozzle 203, so that the nozzle 203 rotates and shifts downward. Both the deviation ring 221 and the correction ring 222 are slidably disposed on the outer wall of the blowpipe 202.

[0065] like Figure 8As shown, when the rectangular plate 207 slides downward, the rectangular plate 207 drives the guide rod 220 to slide downward simultaneously. The guide rod 220 drives the deflection ring 221 and the correction ring 222 to slide downward simultaneously. The deflection ring 221 slides downward and squeezes the nozzle 203, causing the nozzle 203 to deflect downward. When the rectangular plate 207 slides upward, the residual gas in the pipeline is in a pre-emptive state, and the output end of the nozzle 203 is in an inclined downward emptying state. The low-pressure gas sprayed in this way assists in settling, suppresses secondary dust re-entrainment and re-attachment to the filter bag, and improves the settling efficiency. When the rectangular plate 207 slides back to its original position, the correction ring 222 slides back to its original position simultaneously and squeezes the nozzle 203. The correction ring 222 drives the nozzle 203 to rotate back to its original position.

[0066] The synchronous adjustment mechanism 2 drives the nozzle 203 to gradually weaken the pulse jet. At the beginning of the pulse, the filter bag is back-blown by high-pressure gas. After the pulse ends, the low-pressure gas is sprayed downwards by the compression of the space above the cavity 201 to assist in settling, reduce the secondary adsorption of dust on the filter screen and improve the dust removal efficiency.

[0067] The pulse-controlled gas blowing device provided by this invention is used as follows:

[0068] In use, pulse valve 101 opens, and high-pressure gas enters cavity 201 from pulse valve 101. At this time, the high-pressure gas enters the gradient groove 205 from cavity 201, pushing the bottom of the push tube 204, causing the push tube 204 to slide downward. The rectangular plate 207 slides downward along cavity 201 simultaneously. The ball bearings 209 on the push tube 204 squeeze the spiral groove 210 and drive the spray pipe 202 to rotate. The nozzles 203 on the spray pipe 202 rotate simultaneously, and the connecting groove 206 moves synchronously towards... The device slides downwards and connects with the drive hole 219 and nozzle 203. At this time, high-pressure gas is simultaneously ejected from multiple nozzles 203. The nozzles 203 rotate and blow dust off the filter bags. The rectangular plate 207 compresses the spring 208, causing the spring 208 to be compressed. The push tube 204 slides downwards and releases the blockage on the nozzle 203. Simultaneously, the rubber tube 211 on the push tube 204 slides downwards. When the rubber tube 211 impacts the bottom of the housing 1, the device vibrates through a flexible impact, reducing... Dust adheres and clogs the output end of nozzle 203. Rectangular plate 207 drives guide rod 220 to slide downwards synchronously. Guide rod 220 drives deflection ring 221 and correction ring 222 to slide downwards synchronously. The downward sliding of deflection ring 221 squeezes nozzle 203, causing nozzle 203 to deflect downwards. When filter bag cleaning is finished, the elasticity of spring 208 drives rectangular plate 207 and push tube 204 to slide back to their original positions synchronously. Rectangular plate 207 and cavity 201 are seamlessly connected. When rectangular plate 207 slides upwards... During reset, wedge block 217 and jacking tube 204 slide upward synchronously. Wedge block 216 increases the friction of wedge block 217 sliding upward, slowing down the upward reset speed of rectangular plate 207. This slows down the compression of the space above the chamber 201 by rectangular plate 207, allowing the residual gas in the pipeline to be pre-emptied. The output end of nozzle 203 is tilted downward to empty. Correction ring 222 slides upward synchronously to reset and squeezes nozzle 203. The correction ring 222 drives nozzle 203 to rotate and reset.
