Description

Technical Field

[0001] This invention relates to the technical field of converter gas recovery and purification equipment, specifically a high-efficiency, low-consumption separation, purification, and pressure-stabilizing conveying device for converter gas. Background Technology

[0002] The intermittent blowing process of converter steelmaking generates a large amount of converter gas, whose main components are CO, CO2, and N2, accompanied by dust and a small amount of O2. During the converter blowing cycle, the gas volume, pressure, and composition fluctuate drastically and periodically. When recovering converter gas, a separation, purification, pressure stabilization, and conveying device is required.

[0003] However, current equipment on the market cannot simultaneously purify and cool converter gas while dehydrating it in practical applications. This results in an inability to improve the purity of the converter gas, leading to a low calorific value. The gas can only be used as fuel and is difficult to utilize as a high-value chemical raw material. Therefore, we propose a high-efficiency, low-consumption converter gas separation, purification, and pressure-stabilized transportation device to solve the above-mentioned problems. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to propose a high-efficiency and low-consumption separation, purification and pressure stabilization conveying device for converter gas, which has the advantages of dust removal and purification while dehydration and cooling, and solves the problem of low calorific value of converter gas.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A high-efficiency, low-consumption separation, purification, and pressure-stabilizing conveying device for converter gas includes a base. The upper surface of the base is provided with a filtration and cleaning component, a cooling and dehydration component, and a pressure-relieving and purification component. The cooling and dehydration component and the pressure-relieving and purification component are connected by an adsorption component.

[0006] The filtration and cleaning assembly includes a tank fixedly installed on a base. One side of the tank is connected to an air inlet pipe that is connected to the converter's gas outlet. A support ring is fixedly installed inside the tank. A buffer spring is fixedly installed on the top of the support ring. A filter screen is fixedly installed on the top of the buffer spring. A transmission pipe is connected to the top of the tank.

[0007] The cooling and dehydration assembly includes a cooling shell fixedly installed on the upper surface of the base. The top of the cooling shell is connected to one end of the transmission pipe. Inclined semiconductor cooling plates are inserted on both sides of the cooling shell, and the semiconductor cooling plates on both sides are staggered. A conical tube is fixedly installed inside the cooling shell, and an electromagnetic valve is connected to the bottom of the conical tube.

[0008] As a preferred technical solution, a collection tray is inserted into one side of the cooling shell. A support block is fixedly installed on the top of the end of the collection tray outside the cooling shell. A magnetic block is fixedly installed on one side of the support block. A magnetic touch switch is fixedly installed on one side of the cooling shell. A cooling and dehydration component is set up, which uses staggered semiconductor cooling chips to cool down the gas. Water vapor in the gas condenses and is discharged through a cone tube and a solenoid valve. The collection tray, together with the magnetic touch switch, realizes the identification of the collection tray's disassembly and assembly status. A sealing ring ensures the assembly seal. The gas is pre-treated by cooling and dehydration to reduce the water vapor content of the gas, prevent water vapor from entering the adsorption box and causing the adsorption block to fail, ensure the efficiency of subsequent adsorption and purification, and improve the quality of the gas.

[0009] As a preferred technical solution, a sealing ring is fixedly installed on one side of the cooling shell, and one side of the sealing ring is in contact with one side of the collection tray.

[0010] As a preferred technical solution, the pressure relief and purification assembly includes a cylinder fixedly installed on a base, a pressure relief valve connected to the top of the cylinder, a purification chamber connected to one side of the pressure relief valve via a connecting bend, the bottom of the purification chamber being fixedly connected to the top of the cylinder, and an air outlet pipe connected to the top of the purification chamber.

[0011] As a preferred technical solution, the end of the connecting elbow inside the purification chamber is close to the inner bottom wall of the purification chamber, and the end of the air outlet pipe inside the purification chamber is flush with the inner top wall of the purification chamber.

[0012] As a preferred technical solution, an observation hole is provided on one side of the purification chamber, and a transparent observation plate is embedded inside the observation hole. A discharge pipe is connected to one side of the cylinder, with the discharge pipe opening facing downwards.

[0013] As a preferred technical solution, a conical tube is connected to the bottom of the tank, and a control valve is connected to the bottom of the conical tube. The top of the conical tube is fixedly connected to the bottom of the base. By setting up a filter cleaning component, the dust in the converter gas is intercepted and filtered through the cooperation of the internal support ring, buffer spring and filter screen. The buffer spring can buffer the impact of the gas flow and reduce the vibration damage to the filter screen caused by the air flow impact. The filtered dust can be discharged periodically through the conical tube and control valve, which solves the problem that the high dust content of the converter gas can easily cause blockage of the subsequent adsorption components and reduces the maintenance frequency of the subsequent adsorption components.

[0014] As a preferred technical solution, the adsorption assembly includes a bent pipe connected to one side of the cooling shell, one end of the bent pipe is connected to an adsorption box, and a first adsorption block, a second adsorption block and a third adsorption block are fixedly installed inside the adsorption box, and the other side of the adsorption box is connected to one side of the cylinder through a pipe.

[0015] As a preferred technical solution, a sealing plate is provided on the top of the adsorption box, and screws are inserted into the four corners of the top of the sealing plate. The bottom of the screws is threaded to the top of the adsorption box, and screw holes are provided on the sealing plate for the screws to pass through.

[0016] As a preferred technical solution, a support assembly is provided at the bottom of the base. The support assembly includes support frames fixedly installed on both sides of the bottom of the base. An mounting plate is fixedly installed at the bottom of the support frame, and the mounting plate has mounting holes. The mounting holes are oblong holes. The two support frames are fixedly connected by a connecting plate. An adsorption assembly and a pressure relief purification assembly are set up to cooperate. The adsorption box contains multi-stage adsorption blocks to classify and purify impurities in the coal gas. The sealing plate and screws facilitate the replacement of adsorption consumables. The cylinder plays a role in stabilizing pressure and buffering. When there is overpressure, the pressure relief valve guides the overpressured coal gas into the purification box for purification before discharge. This not only achieves stable coal gas transportation but also avoids the safety and environmental hazards caused by the direct release of overpressured coal gas. The entire set of equipment is integrated on the base, and the support assembly is easy to install on site. The equipment has a high degree of integration and occupies a small area.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a filter cleaning component, in which a support ring, a buffer spring, and a filter screen work together to intercept and filter dust in converter gas. The buffer spring can buffer the impact of the gas flow, reducing vibration damage to the filter screen caused by the airflow. The filtered dust can be periodically discharged through a conical tube and a control valve, solving the problem that the high dust content in converter gas can easily cause blockage of subsequent adsorption components and reducing the frequency of maintenance of subsequent adsorption components.

[0018] 2. This invention utilizes a cooling and dehydration component, employing staggered semiconductor cooling chips to cool the coal gas, causing water vapor in the gas to condense and precipitate. The condensate is discharged through a conical tube and an electromagnetic valve. A collection tray, in conjunction with a magnetic touch switch, identifies the collection tray's installation and removal status. A sealing ring ensures a tight seal during assembly. This process pre-treats the coal gas by cooling and dehydrating it, reducing the water vapor content and preventing water vapor from entering the adsorption box and causing adsorption block failure. This ensures efficient subsequent adsorption and purification, and improves the quality of the coal gas.

[0019] 3. This invention combines an adsorption component with a pressure relief and purification component. The adsorption box contains multi-stage adsorption blocks that classify and purify impurities in the coal gas. The sealing plate and screws facilitate the replacement of adsorption consumables. The cylinder acts as a pressure stabilizing buffer. When there is overpressure, the pressure relief valve guides the overpressured coal gas into the purification box for purification before discharge. This achieves stable coal gas transportation and avoids the safety and environmental hazards caused by the direct release of overpressured coal gas. The entire set of equipment is integrated on the base, and the support components facilitate on-site installation. The equipment has a high degree of integration and occupies a small area.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] According to the appendix Figure 1-9 As shown, this embodiment of the invention provides a high-efficiency, low-consumption separation, purification, and pressure-stabilizing conveying device for converter gas, including a base 1. The upper surface of the base 1 is provided with a filtration and cleaning component 2, a cooling and dehydration component 3, and a pressure-relieving and purification component 4. The cooling and dehydration component 3 and the pressure-relieving and purification component 4 are connected by an adsorption component 5. The base 1 serves as the supporting body for the entire machine. The filtration and cleaning component 2, the cooling and dehydration component 3, the adsorption component 5, and the pressure-relieving and purification component 4 are connected in sequence through pipelines according to the gas treatment process, realizing an integrated treatment process for converter gas, including sequential dust removal, cooling and dehydration, adsorption purification, and pressure stabilization and relief.

[0029] The filter cleaning assembly 2 includes a tank 200 fixedly installed on a base 1. One side of the tank 200 is connected to an inlet pipe 201 that communicates with the converter gas outlet. A support ring 202 is fixedly installed inside the tank 200. A buffer spring 203 is fixedly installed on the top of the support ring 202, and a filter screen 204 is fixedly installed on the top of the buffer spring 203. A transmission pipe 205 is connected to the top of the tank 200. In practice, the inlet pipe 201 is connected to the converter gas outlet pipe, and the raw converter gas is introduced into the tank 200 through the inlet pipe 201. The support ring 202 is welded and fixed to the inner wall of the tank 200. Multiple sets of buffer springs 203 are evenly arranged circumferentially on the upper surface of the support ring 202, and the filter screen 204 is mounted above all the buffer springs 203. When the converter gas flow impacts the filter screen 204, the buffer spring 203 can generate elastic deformation to buffer the impact vibration brought by the air flow and reduce the risk of fatigue damage to the filter screen 204. The filter screen 204 intercepts most of the dust particles in the gas. The dust settles downward under the action of gravity, and the filtered gas flows upward and is output from the transmission pipe 205 at the top of the tank 200.

[0030] As a preferred technical solution, the bottom of the tank 200 is connected to a conical tube 206, and the bottom of the conical tube 206 is connected to a control valve 207. The top of the conical tube 206 is fixedly connected to the bottom of the base 1. In this embodiment, the conical tube 206 has a conical structure that is wider at the top and narrower at the bottom, which facilitates the collection of settled dust to the bottom. The dust intercepted by the filter screen 204 falls into the inside of the conical tube 206. On-site operators can periodically open the control valve 207 to discharge the accumulated dust into the tank 200. By setting up the filter cleaning component 2, the dust in the converter gas is intercepted and filtered through the cooperation of the internal support ring 202, buffer spring 203 and filter screen 204 in the tank 200. The buffer spring 203 can buffer the impact of the gas flow and reduce the vibration damage to the filter screen 204 caused by the air flow impact. The filtered dust can be discharged periodically through the conical tube 206 and control valve 207, which solves the problem that the high dust content of the converter gas can easily cause blockage of the subsequent adsorption components and reduces the maintenance frequency of the subsequent adsorption components.

[0031] The cooling and dehydration assembly 3 includes a cooling shell 300 fixedly installed on the upper surface of the base 1. The top of the cooling shell 300 is connected to one end of the transmission pipe 205. Inclined semiconductor cooling chips 301 are inserted on both sides of the cooling shell 300, and the semiconductor cooling chips 301 on both sides are staggered. A tapered tube 302 is fixedly installed inside the cooling shell 300, and a solenoid valve 303 is connected to the bottom of the tapered tube 302. In this embodiment, the gas after being filtered and cleaned by the filter cleaning assembly 2 is sent into the cavity of the cooling shell 300 through the transmission pipe 205. Inside, the semiconductor cooling chips 301, arranged in an alternating and inclined manner on both sides, have their cold ends facing the inner cavity of the cooling shell 300 and their hot ends facing the outer side of the shell. This alternating arrangement can increase the probability of contact between the gas and the cold end of the cooling system, thereby improving the heat exchange and cooling effect. After the high-temperature gas comes into contact with the cold end of the semiconductor cooling chip 301, its temperature drops. The water vapor carried inside the gas condenses upon contact with the cold, forming liquid condensate. The condensate drips and collects inside the cone tube 302. The solenoid valve 303 at the bottom of the cone tube 302 can be opened at regular intervals to discharge the accumulated condensate.

[0032] As a preferred technical solution, a collection tray 304 is inserted into one side of the cooling shell 300. A support block 305 is fixedly installed on the top of the end of the collection tray 304 located outside the cooling shell 300. A magnetic block 306 is fixedly installed on one side of the support block 305, and a magnetic touch switch 307 is fixedly installed on one side of the cooling shell 300. In this embodiment, the collection tray 304 is slidably inserted into the side wall of the cooling shell 300 to collect a small amount of splashed condensate and fine impurities. When the collection tray 304 is fully pushed into the cooling shell 300 and assembled in place, the magnetic block 306 on the support block 305 and the magnetic touch switch 307 attract each other, and the magnetic touch switch 307 outputs a positioning signal. When the collection tray 304 is pulled out for cleaning, the magnetic block 306 disengages from the magnetic touch switch 307, and the magnetic touch switch 307 outputs a disassembly signal, which can be linked to the external control system to provide status prompts, reminding the operator to reset the collection tray 304 after cleaning.

[0033] As a preferred technical solution, a sealing ring 308 is fixedly installed on one side of the cooling shell 300. One side of the sealing ring 308 fits against one side of the collecting tray 304. The sealing ring 308 is fitted into the insertion hole of the cooling shell 300 for the collecting tray 304 to be inserted. After the collecting tray 304 is put into place, the side wall of the collecting tray 304 presses the sealing ring 308 to eliminate the assembly gap and prevent the converter gas inside the cooling shell 300 from leaking from the insertion hole. A cooling and dehydration component 3 is set up, which uses staggered semiconductor cooling chips 301 to cool and dehydrate the gas. Water vapor in the gas condenses and is discharged through the cone tube 302 and the solenoid valve 303. The collecting tray 304, together with the magnetic touch switch 307, realizes the identification of the collection tray's disassembly and assembly status. The sealing ring 308 ensures the assembly seal and completes the cooling and dehydration pretreatment of the gas, reducing the water vapor content of the gas, preventing water vapor from entering the adsorption box 501 and causing the adsorption block to fail, ensuring the efficiency of subsequent adsorption and purification, and improving the gas quality.

[0034] As a preferred technical solution, the adsorption assembly 5 includes a bent pipe 500 connected to one side of the cooling shell 300. One end of the bent pipe 500 is connected to an adsorption box 501. A first adsorption block 502, a second adsorption block 503, and a third adsorption block 504 are fixedly installed inside the adsorption box 501. The other side of the adsorption box 501 is connected to one side of the cylinder 400 through a pipe 505. In this embodiment, the coal gas that has undergone cooling and dehydration treatment is sent into the adsorption box 501 from the side of the cooling shell 300 via the bent pipe 500. The first adsorption block 502, the second adsorption block 503, and the third adsorption block 504 are arranged sequentially along the direction of coal gas flow. The three adsorption blocks can be filled with different functional adsorption materials to sequentially remove residual dust, carbon dioxide, nitrogen, and other impurities from the coal gas, thereby achieving graded separation and purification of the coal gas. After multi-stage adsorption and purification, the coal gas is then transported to the cylinder 400 of the pressure relief purification assembly 4 through the pipe 505.

[0035] As a preferred technical solution, a sealing plate 506 is provided on the top of the adsorption box 501. Screws 507 are inserted into the four corners of the top of the sealing plate 506. The bottom of the screws 507 is threaded to the top of the adsorption box 501. The sealing plate 506 has screw holes for the screws 507 to pass through. When it is necessary to replace the first adsorption block 502, the second adsorption block 503, and the third adsorption block 504 inside the adsorption box 501, the screws 507 at the four corners are unscrewed to remove the sealing plate 506 and replace and maintain the internal adsorption consumables. After the replacement is completed, the sealing plate 506 is covered on the top of the adsorption box 501, and the screws 507 are tightened to press the sealing plate 506, ensuring that the cavity of the adsorption box 501 is sealed and preventing gas leakage.

[0036] As a preferred technical solution, the pressure relief and purification assembly 4 includes a cylinder 400 fixedly installed on the base 1. The top of the cylinder 400 is connected to a pressure relief valve 401, and one side of the pressure relief valve 401 is connected to a purification chamber 403 via a connecting bend 402. The bottom of the purification chamber 403 is fixedly connected to the top of the cylinder 400, and the top of the purification chamber 403 is connected to an outlet pipe 404. The cylinder 400 serves as a pressure stabilizing and buffering chamber. The purified coal gas enters the cylinder 400 for volume buffering, reducing pressure fluctuations caused by intermittent gas supply from the converter and achieving coal gas pressure stabilization. When the coal gas pressure inside the cylinder 400 exceeds the set threshold of the pressure relief valve 401, the pressure relief valve 401 automatically opens, and the overpressured coal gas is introduced into the purification chamber 403 via the connecting bend 402. The purification chamber 403 is filled with a purification and absorption medium to treat the coal gas discharged after pressure relief, and the treated gas is discharged outward through the outlet pipe 404.

[0037] As a preferred technical solution, the end of the connecting bend 402 inside the purification box 403 is close to the inner bottom wall of the purification box 403, and the end of the gas outlet pipe 404 inside the purification box 403 is flush with the inner top wall of the purification box 403. This structure allows the depressurized gas to enter from the bottom of the purification box 403, pass upward through the purification medium, and then be discharged from the gas outlet pipe 404 at the top, thus extending the contact path of the gas inside the purification box 403 and improving the purification effect.

[0038] As a preferred technical solution, an observation hole is provided on one side of the purification box 403, and a transparent observation plate is embedded inside the observation hole. A discharge pipe 405 is connected to one side of the cylinder 400, with the outlet of the discharge pipe 405 facing downward. Operators can directly observe the state of the medium inside the purification box 403 through the transparent observation plate, which facilitates timely replacement of the failed purification medium. If condensate waste liquid accumulates inside the cylinder 400, the waste liquid can be discharged outward through the downward-facing discharge pipe 405.

[0039] As a preferred technical solution, a support assembly 6 is provided at the bottom of the base 1. The support assembly 6 includes support frames 600 fixedly installed on both sides of the bottom of the base 1. An installation plate 601 is fixedly installed at the bottom of the support frame 600. The installation plate 601 has an installation hole, which is an elongated oval hole. The two support frames 600 are fixedly connected by a connecting plate 602. The support frame 600 and the connecting plate 602 are welded into an integral frame structure to provide stable support for the base 1. The installation plate 601 at the bottom has an elongated oval installation hole, which allows for fine adjustment of the installation alignment position of the machine during on-site installation. The entire machine is then fixed with bolts, which can accommodate the installation hole position deviation of the on-site installation foundation and improve the assembly adaptability of the device.

[0040] The adsorption component 5 is set up in conjunction with the pressure relief and purification component 4. The multi-stage adsorption blocks inside the adsorption box 501 perform graded adsorption and purification of impurities in the coal gas. The sealing plate 506 and screws 507 facilitate the replacement of adsorption consumables. The cylinder 400 plays a role in stabilizing pressure and buffering. When there is overpressure, the pressure relief valve 401 introduces the overpressured coal gas into the purification box 403 for purification before discharge. This not only achieves stable coal gas transportation but also avoids the safety and environmental hazards caused by the direct release of overpressured coal gas. The entire set of equipment is integrated on the base 1, and the support component 6 facilitates on-site installation. The equipment has a high degree of integration and occupies a small area.

[0041] In use, the converter gas high-efficiency and low-consumption separation, purification and pressure stabilization conveying device of the present invention delivers the converter gas into the tank 200 of the filter cleaning component 2 through the inlet pipe 201. The gas impacts the filter screen 204, and the buffer spring 203 and support ring 202 below the filter screen 204 provide elastic support for the filter screen 204. The dust in the gas is intercepted and filtered by the filter screen 204. The intercepted dust falls downward under the action of gravity and collects in the conical pipe 206 at the bottom of the tank 200. The dust can be discharged in a timed manner through the control valve 207. The filtered converter gas is conveyed from the transmission pipe 205 at the top of the tank 200 to the cooling shell 300 of the cooling and dehydration component 3.

[0042] After the gas enters the cooling shell 300, the staggered and inclined semiconductor cooling chips 301 cool the gas inside the shell. The water vapor contained in the gas condenses into liquid water upon cooling. The condensate collects downwards along the cone tube 302 and is drained by the solenoid valve 303. A collection tray 304 is inserted into the side of the cooling shell 300. The support block 305 and magnetic block 306 on the collection tray 304 cooperate with the magnetic touch switch 307 of the cooling shell 300. When the collection tray 304 is pulled out, the magnetic touch switch 307 is triggered to provide a status indication. The sealing ring 308 ensures that the assembly position of the collection tray 304 and the cooling shell 300 is sealed to prevent gas leakage.

[0043] After cooling and dehydration, the coal gas is sent into the adsorption box 501 of the adsorption assembly 5 through the bend pipe 500. The adsorption box 501 is arranged with the first adsorption block 502, the second adsorption block 503, and the third adsorption block 504 in sequence. The multi-stage adsorption blocks adsorb and remove residual impurities, some carbon dioxide, and nitrogen in the coal gas in sequence, so as to achieve coal gas separation and purification. The top of the adsorption box 501 is locked with the sealing plate 506 by screws 507, which facilitates the disassembly and replacement of the internal adsorption blocks. The coal gas after adsorption and purification is transported into the cylinder 400 of the pressure relief and purification assembly 4 through the pipe 505.

[0044] The cylinder 400 internally stabilizes and buffers the gas pressure. When the gas pressure inside the device exceeds the set threshold, the pressure relief valve 401 opens, and the overpressure gas is introduced into the purification box 403 through the connecting bend 402. The gas outlet end of the connecting bend 402 is close to the bottom wall of the purification box 403. After the gas is treated by the purification medium inside the box, it is discharged outward from the gas outlet pipe 404 close to the inner top wall, preventing the direct leakage of toxic and harmful gas. The bottom of the cylinder 400 is connected to the downwardly arranged discharge pipe 405, which can discharge the condensate waste liquid accumulated in the cylinder. All components of the entire device are installed on the base 1. The support assembly 6 at the bottom of the base 1 consists of a support frame 600, a mounting plate 601, and a connecting plate 602. The mounting plate 601 with an elongated hole is easy to align and fix on site, ensuring the stability of the whole machine operation.
