Description

Technical Field

[0001] This utility model relates to the field of gas compression and recovery technology, and in particular to an adaptive energy-saving industrial gas compression and recovery system. Background Technology

[0002] The system can automatically adjust its operating status based on parameters such as the actual flow rate and pressure of gas generated in industrial production. When the gas output is low, the system will automatically reduce the speed of the compressor or reduce the number of compressors in operation to avoid the equipment running idle or over-operating, thereby reducing energy consumption.

[0003] A search revealed that publication number CN214437284U discloses a compressed gas recovery system, comprising: a recovery branch, a pressure accumulator, and a pressure relief branch, all connected to a blow molding nozzle. A first solenoid valve is installed between the recovery branch and the nozzle; a second solenoid valve is installed between the pressure accumulator and the blow molding nozzle; and a third solenoid valve is installed between the pressure relief branch and the blow molding nozzle. The recovery branch sequentially includes a vacuum pump, a first filter, and a first dryer, with the first dryer connected to the inlet of the pressure accumulator. The inlet of the pressure accumulator is also connected to a replenishment branch, which sequentially includes an air compressor pump, a second filter, a second dryer, and a pressure tank, with the outlet of the pressure tank connected to the pressure accumulator. The pressure relief branch includes a third filter.

[0004] In existing technologies, after prolonged use, filters will intercept a large amount of dust, particles and other impurities, causing the filter pores to become smaller and the air resistance to increase. Furthermore, as impurities continue to accumulate, the filtration efficiency of the filter in the adaptive energy-saving industrial gas compression and recovery system will gradually decrease, making it unable to effectively remove impurities from the industrial gas. This leads to a decline in the gas quality of the subsequent compression and recovery system, affecting the purity and quality of the final recovered gas. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adaptive energy-saving industrial gas compression and recovery system, which aims to solve the problem in the prior art that as impurities accumulate, the filter cannot effectively remove impurities from the industrial gas, resulting in a decline in the gas quality of the subsequent compression and recovery system and affecting the purity and quality of the final recovered gas.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adaptive energy-saving industrial gas compression and recovery system, comprising a filter, an impeller rotatably connected to the inner wall of the filter, a fixed rod fixedly connected to the inner wall of the impeller, a filter disc rotatably connected to the outer wall of the fixed rod, the outer wall of the filter disc fixedly connected to the inner wall of the filter, a fixed gear fixedly connected to the outer wall of the fixed rod, a rack meshing with the teeth of the fixed gear, a telescopic scraper fixedly connected to the outer wall of the rack, a sliding column fixedly connected to the inner wall of the telescopic scraper, the outer wall of the sliding column slidably connected to the inner wall of the filter, a filter screen fixedly connected to the inner wall of the filter, the outer wall of the filter screen fixedly connected to the outer wall of the filter disc, the outer wall of the telescopic scraper slidably connected to the outer wall of the filter screen, a collection box detachably installed on the outer wall of the filter, and a compression assembly provided on the outer wall of the filter.

[0007] Through the above technical solution: when gas passes through the impeller, it drives the impeller to rotate on the inner wall of the filter, which can prevent it from falling off. When the impeller rotates, it drives the fixed rod to rotate on the inner wall of the filter, which can also prevent it from falling off. When the fixed rod drives the fixed gear to rotate, it drives the racks on both sides to slide. While the upper rack drives the left telescopic scraper to slide, the upper rack slides on the inner wall of the right telescopic scraper. The lower rack drives the right telescopic scraper to slide, and the lower rack slides on the inner wall of the left telescopic scraper, which can achieve a stable reciprocating sliding effect. When the telescopic scraper slides back and forth, the sliding column on its inner wall slides on the inner wall of the filter, which can adjust the length of the telescopic scraper to achieve a stable cleaning effect. The contaminants cleaned by the telescopic scraper fall into the inside of the collection box. When the collection box is disassembled, the contaminants can be centrally processed to prevent accumulation.

[0008] As a further description of the above technical solution:

[0009] The compression assembly includes a low-pressure pipe, the outer wall of which is detachably mounted on the outer wall of the filter. A controller is fixedly connected to the upper surface of the low-pressure pipe, and a sensor is provided on the lower surface of the controller. The outer wall of the sensor is detachably mounted on the inner wall of the low-pressure pipe. A variable frequency motor is provided on the upper surface of the controller. A compressor is detachably mounted on the outer wall of the filter. A variable frequency motor is provided on the outer wall of the compressor. A separation assembly is provided on the outer wall of the compressor.

[0010] The above technical solution involves starting a variable frequency motor to drive the controller and controlling the sensors. Multiple sensors installed on the inner wall of the low-pressure pipeline can monitor gas flow, pressure, and temperature parameters in real time. After the gas passes through the filter, it enters the compressor. The compressor is a water-lubricated single-screw compressor. After starting a variable frequency motor to drive the compressor and pressurize the gas, it enters the separation component, achieving water-gas separation. The processed gas then enters the high-pressure tank for compression and recovery.

[0011] As a further description of the above technical solution:

[0012] The separation assembly includes a water-gas separator, the inner wall of which is fixedly connected to the outer wall of the compressor, and a high-pressure tank is fixedly connected to the inner wall of the water-gas separator.

[0013] The above technical solution allows the gas to pass through a cooling plate when it enters the water-gas separator, achieving the effect of cooling and collecting moisture. At the same time, the gas is transported to the interior of the high-pressure tank through the auger blades, achieving a stable separation of water and gas.

[0014] As a further description of the above technical solution:

[0015] A cooling plate is fixedly connected to the inner wall of the water-air separator, a reciprocating screw is rotatably connected to the inner wall of the water-air separator, and an impeller is fixedly connected to the outer wall of the reciprocating screw.

[0016] With the above technical solution, the gas drives the second impeller to rotate as it passes through the cooling plate, and the rotation of the second impeller drives the reciprocating screw to rotate on the inner wall of the water-gas separator, thus achieving a stable rotation effect.

[0017] As a further description of the above technical solution:

[0018] A hollow block is rotatably connected to the outer wall of the reciprocating lead screw, and the outer wall of the hollow block is fixedly connected to the inner wall of the water-air separator.

[0019] The above technical solution achieves the effect of preventing the reciprocating screw from deviating by rotating the reciprocating lead screw on the inner wall of the hollow block, while the hollow block is fixed on the inner wall of the water-air separator. The bevel gears 2 and 1 rotating on the inner wall of the hollow block achieve the effect of stable transmission.

[0020] As a further description of the above technical solution:

[0021] A cleaning plate is slidably connected to the outer wall of the reciprocating lead screw, the outer wall of the cleaning plate is slidably connected to the outer wall of the cooling plate, and the outer wall of the cleaning plate is slidably connected to the inner wall of the water-air separator.

[0022] Through the above technical solution: the reciprocating screw rotation can drive the cleaning plate to slide back and forth on the outer wall of the cooling plate and the inner wall of the water-air separator, which can achieve the effect of stable cleaning of water. At the same time, the impeller rotation can throw water to the bottom of the water-air separator, which can facilitate the discharge of water.

[0023] As a further description of the above technical solution:

[0024] The outer wall of the reciprocating lead screw is fixedly connected to a bevel gear one, the tooth end of the bevel gear one is meshed with a bevel gear two, the outer wall of the bevel gear two is rotatably connected to the inner wall of the hollow block, and the outer wall of the bevel gear two is rotatably connected to the inner wall of the cooling plate.

[0025] The above technical solution involves using a reciprocating screw to drive bevel gear one to rotate, which in turn drives bevel gear two to rotate on the inner wall of the hollow block and cooling plate. This prevents bevel gear two from falling off, thus enabling bevel gear two to stably drive bevel gear three to rotate.

[0026] As a further description of the above technical solution:

[0027] The tooth end of the second bevel gear is meshed with the third bevel gear. The inner wall of the third bevel gear is fixedly connected to a rotating column. The outer wall of the rotating column is rotatably connected to the inner wall of the water-air separator. The outer wall of the rotating column is fixedly connected to an auger blade.

[0028] The above technical solution involves driving bevel gear three to rotate via bevel gear two, which in turn drives the rotating column to rotate on the inner wall of the hollow block. Simultaneously, the rotating column rotates on the inner wall of the water-gas separator, thus preventing the rotating column from falling off. The rotating column drives the auger blade to rotate, thereby enabling the auger blade to stably transmit gas into the high-pressure tank.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the impeller is driven by gas to rotate, which drives the fixed rod to rotate on the inner wall of the filter. At the same time, the fixed rod drives the fixed gear to rotate, which drives the rack to slide, so that the rack drives the telescopic scraper to slide on the outer wall of the filter screen. The telescopic scraper can clean the filter screen back and forth, thereby maintaining the filtration efficiency and keeping the purity and quality of the final recovered gas.

[0031] 2. In this utility model, the impeller is driven to rotate by high-pressure gas, and the reciprocating screw fixed on the inner wall of the impeller drives the cleaning plate to slide back and forth. The rotation of the reciprocating screw drives the first bevel gear to rotate, and the first bevel gear drives the second bevel gear to rotate at the same time, while the third bevel gear rotates synchronously. The rotating column drives the auger blade to rotate. The cleaning plate can stably collect moisture in the gas and stably transmit the gas, thereby improving the efficiency and stability of water-gas separation. Attached Figure Description

A fixing gear 104 is fixedly connected to the outer wall of the fixing rod 102. A rack 105 is meshed with the tooth end of the fixing gear 104. A telescopic scraper 106 is fixedly connected to the outer wall of the rack 105. A sliding column 107 is fixedly connected to the inner wall of the telescopic scraper 106. The outer wall of the sliding column 107 is slidably connected to the inner wall of the filter 1. A filter screen 108 is fixedly connected to the inner wall of the filter 1. The outer wall of the filter screen 108 is fixedly connected to the outer wall of the filter element 103. The outer wall of the telescopic scraper 106 is slidably connected to the outer wall of the filter screen 108, and the outer wall of the telescopic scraper 106 is slidably connected to the outer wall of the filter sheet 103. A collection box 109 is detachably installed on the outer wall of the filter 1. A compression assembly 2 is provided on the outer wall of the filter 1. The compression assembly 2 includes a low-pressure pipe 201. The outer wall of the low-pressure pipe 201 is detachably installed on the outer wall of the filter 1. A controller 202 is fixedly connected to the upper surface of the low-pressure pipe 201. A sensor is provided on the lower surface of the controller 202. The outer wall of the sensor is detachably installed on the inner wall of the low-pressure pipe 201. A variable frequency motor 203 is provided on the upper surface of the controller 202. A compressor 204 is detachably installed on the outer wall of the filter 1. A variable frequency motor 205 is provided on the outer wall of the compressor 204. A separation assembly 3 is provided on the outer wall of the compressor 204.

[0040] Specifically, when gas enters the low-pressure pipeline 201, the variable frequency motor 203 drives the controller 202 to control multiple sensors on the inner wall of the low-pressure pipeline 201, achieving real-time monitoring of gas flow, pressure, and temperature. When gas enters the filter 1, the gas drives the impeller 101 to rotate on the inner wall of the filter 1. The rotation of the impeller 101 drives the fixed rod 102 to rotate on the inner wall of the filter disc 103. The filter disc 103 is fixed to the inner wall of the filter 1, preventing the fixed rod 102 from falling off. The fixed rod 102 drives the fixed gear 104 to rotate, which in turn drives the rack 105 to rotate. The rack 105 then drives the telescopic scraper 106 to slide, achieving a reciprocating sliding effect. The sliding column 107, which rotates on the inner wall of the filter 1, slides on the inner wall of the filter 1, allowing the telescopic scraper 106 to slide and clean the filter screen 108 while being able to extend and retract, achieving a stable cleaning effect. The telescopic scraper 106 cleans the contaminants into the collection box 109. When the collection box 109 is removed, the contaminants can be centrally processed. When the cleaned gas enters the compressor 204, the variable frequency motor 205 is started to drive the compressor 204 to rotate, achieving a stable pressurization effect. After the pressurized gas passes through the water-gas separator 301, it enters the high-pressure tank 206, achieving a compression and recovery effect. The telescopic scraper 106 can reciprocate to clean the filter screen 108, maintaining filtration efficiency and ensuring the purity and quality of the final recovered gas.

[0041] Reference Figure 1 and Figure 4 The separation component 3 includes a water-air separator 301. The inner wall of the water-air separator 301 is fixedly connected to the outer wall of the compressor 204. A high-pressure tank 206 is fixedly connected to the inner wall of the water-air separator 301. A cooling plate 302 is fixedly connected to the inner wall of the water-air separator 301. A reciprocating screw 303 is rotatably connected to the inner wall of the water-air separator 301. An impeller 304 is fixedly connected to the outer wall of the reciprocating screw 303. A hollow block 305 is rotatably connected to the outer wall of the reciprocating screw 303. The outer wall of the hollow block 305 is fixedly connected to the inner wall of the water-air separator 301. A cleaning plate 307 is slidably connected to the outer wall of the reciprocating screw 303. The outer wall of the cleaning plate 307 is slidably connected to the outer wall of the cooling plate 302. The outer wall of the cleaning plate 307 is slidably connected to the inner wall of the water-air separator 301.

[0042] Specifically, when the gas enters the water-gas separator 301, it passes through the cooling plate 302 to achieve stable cooling and water collection. The gas drives the impeller 304 to rotate, which in turn drives the reciprocating screw 303 to rotate on the inner wall of the water-gas separator 301, thus preventing deviation. The rotation of the reciprocating screw 303 drives the cleaning plate 307 to slide on the outer wall of the cooling plate 302, thus achieving the effect of reciprocating water cleaning.

[0043] Reference Figure 4 A bevel gear 306 is fixedly connected to the outer wall of the reciprocating screw 303. A bevel gear 308 is meshed with the tooth end of the bevel gear 306. The outer wall of the bevel gear 308 is rotatably connected to the inner wall of the hollow block 305. The outer wall of the bevel gear 308 is rotatably connected to the inner wall of the cooling plate 302. A bevel gear 310 is meshed with the tooth end of the bevel gear 308. A rotating column 309 is fixedly connected to the inner wall of the bevel gear 310. The outer wall of the rotating column 309 is rotatably connected to the inner wall of the water-air separator 301. An auger blade 311 is fixedly connected to the outer wall of the rotating column 309.

[0044] Specifically, the reciprocating screw 303 drives the first bevel gear 306 to rotate, which in turn drives the second bevel gear 308 to rotate on the inner wall of the hollow block 305, achieving a stable transmission effect. The reciprocating screw 303 rotates on the inner wall of the hollow block 305, which is fixed to the inner wall of the water-air separator 301, preventing the reciprocating screw 303 from falling off. The second bevel gear 308 rotates on the inner wall of the cooling plate 302, achieving stable rotation. The second drive 308 drives the third bevel gear 310 to rotate, which in turn drives the rotating column 309 to rotate on the inner wall of the water-gas separator 301. This allows the rotating column 309 to rotate stably. The rotating column 309 drives the auger blade 311 to rotate on the inner wall of the water-gas separator 301, thus achieving a stable gas transfer to the high-pressure tank 206. The cleaning plate 307 can stably collect moisture from the gas and also stably transfer the gas, thereby improving the efficiency and stability of water-gas separation.

[0045] Working principle: When the device is needed, the variable frequency motor 203 drives the controller 202 to control the sensor on the inner wall of the low-pressure pipeline 201, which can achieve real-time monitoring of gas flow, pressure and temperature. When the gas passes through the impeller 101, it drives the fixed rod 102 to rotate on the inner wall of the filter 103. The filter 103 is fixed on the inner wall of the filter 1, which can prevent the fixed rod 102 from falling off. The fixed rod 102 drives the fixed gear 104 to rotate, which drives the rack 105 to slide. The sliding of the rack 105 drives the telescopic scraper 106 to slide back and forth on the outer wall of the filter screen 108, which can achieve a stable cleaning effect. The telescopic scraper 106 drives the sliding column 107 to slide on the inner wall of the filter 1, which can achieve the effect of adjusting the telescopic scraper 106. The collection box 109 installed on the inner wall of the filter 1 can achieve the effect of centralized cleaning of pollutants.

[0046] The cleaned gas enters the compressor 204, and the variable frequency motor 205 is started to drive the compressor 204 to rotate, which enables the compressor 204 to achieve a stable pressurization effect. When the pressurized gas enters the water-gas separator 301, the gas will pass through the cooling plate 302 to achieve the effect of cooling and collecting moisture. At the same time, the gas will drive the impeller 2 304 to rotate, and the impeller 2 304 will drive the reciprocating screw 303 to rotate, which will drive the cleaning plate 307 to slide back and forth, achieving the effect of cleaning the moisture attached to the outer wall of the cooling plate 302. The reciprocating screw 303 drives the bevel gear 1 306 to rotate, which in turn drives the bevel gear 2 308 to rotate on the inner wall of the hollow block 305, achieving a stable transmission effect.

[0047] The rotation of bevel gear 2 308 on the inner wall of cooling plate 302 prevents it from falling off. Bevel gear 2 308 drives bevel gear 310 to rotate, which in turn drives rotating column 309 to rotate on the inner wall of water-gas separator 301. Rotating column 309 then drives auger blade 311 to rotate on the inner wall of water-gas separator 301, achieving a stable gas transfer to high-pressure tank 206. This recovery system not only performs reciprocating cleaning to maintain filtration efficiency and preserve the purity and quality of the final recovered gas, but also stably collects moisture from the gas and stably transfers the gas, thus improving the efficiency and stability of water-gas separation.
