Description
Technical Field
[0001] The utility model relates to the technical field of dust removal cyclones, in particular to a multi-air duct combined high-temperature fuel gas dust removal and purification cyclone. Background Art
[0002] Gas refers to various gaseous fuels that release heat when burned. Commonly used gases include natural gas, liquefied petroleum gas, and artificial gas. These gases are typically mixtures of combustible components such as hydrocarbons, hydrogen, and carbon monoxide, and non-combustible components such as carbon dioxide, nitrogen, and oxygen. High-temperature gas dust removal and purification cyclones are devices used to remove dust from high-temperature gases. They are commonly used in industrial processes, particularly when processing high-temperature pyrolysis gas and biomass fuel gas. Cyclone dust collectors rely on the centrifugal force generated by high-speed rotating airflow to separate dust particles from the gas.
[0003] Traditional high-temperature gas dust removal and purification cyclones consist of a cyclone barrel, an exhaust pipe, and an intake pipe. Dust-laden gas enters the cyclone barrel through the intake pipe, forming a swirling airflow inside the barrel. Centrifugal force pushes dust particles toward the cyclone barrel wall, where they slide down the wall and into the ash hopper. The swirling airflow continues to rise to the top and is discharged through the exhaust pipe, completing the dust and gas separation process.
[0004] When the gas rises and is discharged from the outlet pipe of the traditional high-temperature gas dust removal and purification cyclone, some fine dust particles are discharged along with the air flow, which will pollute the environment and affect the air quality of the surrounding area. Therefore, a multi-duct combined high-temperature gas dust removal and purification cyclone is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0033] Reference Figure 1-Figure 4, The utility model provides an embodiment of a multi-air duct combined high-temperature gas dust removal and purification cyclone, including a cylinder 1, an air outlet pipe 9 is provided inside the cylinder 1, and a mounting ring 10 is fixedly connected to the side wall of the air outlet pipe 9, and a filter screen 11 is provided inside the mounting ring 10, and the filter screen 11 is used to capture fine dust particles that have not been completely separated by the cyclone. A shell 12 is provided inside the mounting ring 10, and the side wall of the shell 12 is slidably connected to the inside of the filter screen 11, and a rotating column 13 is rotatably connected to the inside of the shell 12, and one end of the rotating column 13 is fixedly connected to the connecting handle 14, and the other end of the rotating column 13 is fixedly connected to a threaded block 15, and the side wall of the threaded block 15 is threadedly connected to the inside of the shell 12, and a spring 16 is provided inside the shell 12, and the spring 16 is used to push the connecting block 17, and one end of the spring 16 is fixedly connected to the side wall of the threaded block 15, and the other end of the spring 16 is fixedly connected to the connecting block 17, and the connecting block 17 is used to squeeze the card ball 18, and the inside of the shell 12 A card ball 18 is provided, and the card ball 18 is used to fix the filter screen 11. The lower surface of the connecting block 17 is fixedly connected to the bottom block 19. The side wall of the cylinder 1 is provided with a fixing assembly for fixing the cylinder 1. The fixing assembly includes a mounting plate 4, and the side wall of the cylinder 1 is fixedly connected to the inside of the mounting plate 4. The lower surface of the mounting plate 4 is fixedly connected to the bracket 5. The side wall of the cylinder 1 is fixedly connected to the air intake pipe 1 2, and the side wall of the cylinder 1 is fixedly connected to the air intake pipe 2 3. A cone 6 is provided on the lower surface of the cylinder 1. The side walls of the cylinder 1 and the cone 6 are fixedly connected to the flange ring 7. The flange ring 7 is internally threaded with a bolt 8. Through the action of the flange ring 7 and the bolt 8, the cylinder 1 and the cone 6 are disassembled, which is easy to transport and convenient for cleaning the interior. The side wall of the connecting block 17 is slidably connected to the inside of the shell 12, the side wall of the card ball 18 is slidably connected to the side wall of the connecting block 17, the side wall of the card ball 18 is slidably connected to the inside of the filter screen 11, and the side wall of the bottom block 19 is slidably connected to the inside of the filter screen 11;
[0034] When operating the equipment, it is first necessary to ensure that the gas enters the interior of the cylinder 1 smoothly through the air inlet pipe 1 2 and the air inlet pipe 2 3. After entering the cylinder 1, the gas will flow along the designed path and enter the interior of the cyclone. The cyclone can make the gas produce high-speed rotation therein. As the gas rotates inside the cyclone, the particles contained therein will be affected by centrifugal force, and the centrifugal force will cause these particles to move toward the outer wall. Because the heavier particles are gradually pushed toward the outer wall of the cyclone under the action of centrifugal force, as the airflow continues to rotate, these particles will continue to collide with the wall of the cyclone. When the particles collide with the wall, they will slide down along the wall and finally fall into the bottom of the cone 6. The design of the cone 6 allows the particles to slide smoothly into the dust collecting hopper, thereby completing the separation of the particles and the gas. After the efficient treatment of the cyclone, the particles in the airflow are effectively The separated gas is discharged through the exhaust pipe 9, and the purified gas continues to be discharged through the exhaust pipe 9. In order to ensure the continuous and efficient operation of the equipment, the filter 11 needs to be cleaned and maintained regularly. When the filter 11 needs to be removed, it is first necessary to rotate the connecting handle 14. This action will drive the rotating column 13 to rotate. The rotation of the rotating column 13 will cause the threaded block 15 to rotate and move upward, so that the spring 16 loses its squeezing effect, and the spring 16 will slowly rebound. As the spring 16 rebounds, the squeezing of the connecting block 17 on the card ball 18 will also be released. At this time, by lifting the connecting handle 14, the shell 12 can be easily taken out, and then the filter 11 can be removed for necessary cleaning and maintenance. The filter 11 can capture tiny particles that the cyclone cannot effectively separate, which can further improve the dust removal efficiency of the entire dust removal system, ensure that the dust content in the discharged gas is reduced to a minimum, and help reduce air pollution.
[0035] Reference Figure 5 , a water tank 20 is fixedly connected to the upper surface of the mounting plate 4, and a cooler 22 is fixedly connected to the upper surface of the mounting plate 4. The cooler 22 is used to cool water. A piston 21 is provided on the upper surface of the water tank 20, and water is filled into the water tank 20 by opening the piston 21. A water pump 23 is fixedly connected to the upper surface of the cooler 22. The input end of the water pump 23 is fixedly connected to an input pipe 24, one end of the input pipe 24 is fixedly connected to the inside of the water tank 20, and the output end of the water pump 23 is fixedly connected to an output pipe 28. One end of the output pipe 28 is fixedly connected to the inside of the cooler 22. A cooling pipe 25 is fixedly connected to the side wall of the cooler 22. The cooling pipe 25 is used to absorb the heat generated inside the cylinder 1. The side wall of the cooling pipe 25 fits the side wall of the air outlet pipe 9. One end of the cooling pipe 25 is fixedly connected to the inside of the water tank 20. A switch valve 26 is provided on the side wall of the cooling pipe 25. The side wall of the cooling pipe 25 is fixedly connected to a fixing block 27. The fixing block 27 is used to fix the cooling pipe 25, and the side wall of the fixing block 27 is fixedly connected to the side wall of the cylinder 1.
[0036] During the operation of the equipment, the water pump 23 can be started, and the water pump 23 will pump out the water stored in the water tank 20 and transport it to the cooler 22. The purpose of this process is to allow the water to be cooled in the cooler 22 to achieve the desired cooling effect. Then, by operating the switch valve 26, the cooled water flow is introduced into the cooling pipe 25. The cooling pipe 25 fits tightly with the exhaust pipe 9, which can effectively absorb the heat generated by the gas during the combustion process. In this way, the temperature inside the cylinder 1 is reduced, thereby ensuring the normal operation and safety of the equipment. Finally, the cooled water flow is transported back to the water tank 20 through the cooling pipe 25 again, realizing the recycling of the water flow, which not only saves water resources but also improves the operating efficiency of the equipment. The service life of the cyclone and its internal components can be extended by cooling. By internal cooling, equipment failures and maintenance requirements caused by high temperature can be reduced, thereby reducing long-term operating costs.
[0037] Working principle: When the device is used, the gas enters the cylinder 1 through the air inlet pipe 1 2 and the air inlet pipe 2 3. The gas generates a rotational motion inside the cyclone due to the designed structure. This rotation causes the particles in the gas to be affected by centrifugal force and move toward the outer wall. As the airflow rotates, the heavier particles are forced to approach the outer wall of the cyclone due to the centrifugal force. After colliding with the wall, these particles will slide down along the wall and eventually fall from the cone 6 into the prepared dust hopper. After being processed by the cyclone, the particles in the airflow are separated, and the purified gas flows out of the cyclone through the outlet pipe 9 and then through the filter 11. When the filter 11 needs to be disassembled after long-term use, first rotate the connecting handle 14 to drive the rotating column 13 to rotate, and rotate the threaded block 15 to move it upward, so that the spring 16 loses its squeeze and slowly rebounds, and then the connecting block 17 releases the squeeze on the stuck ball 18. At this time, lift the connecting handle 14 to remove the filter. The shell 12 is taken out, and the filter 11 is removed for cleaning and maintenance. During the operation of the equipment, the water pump 23 can be started to pump the water inside the water tank 20 into the cooler 22 to cool it down. Then, the cooled water flow is input into the cooling pipe 25 by opening the switch valve 26. Since the cooling pipe 25 is in contact with the exhaust pipe 9, the heat generated by the gas is absorbed to achieve the effect of cooling the inside of the cylinder 1. Finally, the water flow is brought into the water inlet tank 20 again through the cooling pipe 25 to achieve the effect of recycling the water flow.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
