Description

Technical Field

[0001] This application relates to the technical field of cyclone separation, and particularly to a clean thermal power cyclone separator. Background Art

[0002] A cyclone separator is a device that uses centrifugal force to separate solid particles or liquid droplets in a gas stream. Its principle is based on the rotational motion caused by the tangential introduction of the gas stream, which causes solid particles or liquid droplets with a large inertial centrifugal force to be thrown towards the outer wall and separated. A cyclone separator is a widely used solid-gas separation device in industry; thermal power generation belongs to a type of thermal power generation technology. When the combustion in thermal power generation is incomplete, a large amount of dusty gas will be generated, and it is necessary to effectively separate the impurities inside the dusty gas.

[0003] Currently, when the existing cyclone separators are in use, they usually have the following defects: 1. When the existing cyclone separators filter and separate dusty gas, the centrifugal effect is poor, the impurities inside the gas are not completely separated, and the gas cannot be secondarily over-separated; 2. When the existing equipment filters unburned high-temperature gas, it cannot accurately collect combustible impurities, and the collected combustible impurities cannot be effectively cleaned, which affects the gas discharge rate. Summary of the Invention

[0004] In order to achieve the function of filtering and separating the flue gas generated by thermal power generation, this application provides a clean thermal power cyclone separator.

[0005] A clean thermal power cyclone separator provided by this application adopts the following technical solutions:

[0006] A clean thermal power cyclone separator includes a support frame, a cyclone separation module, an air inlet pipe, and a sealing end cover. There are multiple support frames, and a cyclone separation module is installed between the upper ends of the support frames. An air inlet pipe is installed at the upper left end of the cyclone separation module, and a sealing end cover is detachably installed at the upper end of the cyclone separation module. Exhaust holes are evenly arranged on the sealing end cover.

[0007] The cyclone separation module includes a housing frame, a cyclone separation unit, an annular frame, a rotating unit, a filtering unit, and a discharge rack. The housing frame has a cylindrical hollow structure. A cyclone separation unit is arranged inside the housing frame. The lower end of the cyclone separation unit is connected to the inner wall of the housing frame through an annular frame. The upper end of the cyclone separation unit is connected to the rotating unit. The rotating unit is installed at the upper end inside the housing frame. The middle part of the cyclone separation unit is hollow. A filtering unit is installed at the upper end inside the cyclone separation unit. A discharge rack is installed at the lower end of the housing frame, and the discharge rack has a conical structure.

[0008] The cyclone separation unit includes an inner sleeve, a connecting sleeve, and stirring vanes. The inner sleeve is a cylindrical hollow structure. A connecting sleeve is installed at the lower end of the outer side of the inner sleeve. Card slots are uniformly arranged on the outer side surface of the connecting sleeve, and stirring vanes are installed in the card slots.

[0009] By adopting the above technical solution, the cyclone separation unit rotates at high speed to drive the flue gas generated by thermal power generation to rotate synchronously. The high-speed rotation of the flue gas generates centrifugal force, causing solid particles with greater inertial centrifugal force to be thrown towards the wall surface of the housing frame and separated, thereby achieving the function of solid-gas separation.

[0010] Preferably, the stirring vanes are arranged in an inclined structure. A negative pressure chamber is arranged between adjacent stirring vanes. Negative pressure holes are uniformly arranged on the inner sleeve and the connecting sleeve, and the negative pressure holes are located between the negative pressure chambers.

[0011] By adopting the above technical solution, when the stirring vanes rotate at high speed, a negative pressure chamber is formed between adjacent stirring vanes. When gas enters the inside of the inner sleeve, the gas that has not passed through completely enters the negative pressure chamber again through the negative pressure holes. Under the rotational action of the stirring vanes, the gas can be separated for the second time, improving the separation effect of the dust-containing gas.

[0012] Preferably, the cross-section of the negative pressure hole is in a conical structure, and the diameter of the cross-section of the negative pressure hole gradually decreases from inside to outside.

[0013] By adopting the above technical solution, the outer diameter of the negative pressure hole is smaller than the inner diameter, preventing gas from directly entering the inside of the inner sleeve and ensuring the separation effect of the dust-containing gas.

[0014] Preferably, the rotating unit includes a fixed frame, a rotating frame, a driving motor, a rotating gear, and an annular gear. A fixed frame is installed at the upper end inside the housing frame. The fixed frame is a ring-shaped structure with a U-shaped cross-section. The rotating frame is installed inside the fixed frame through a bearing. A groove is arranged on the fixed frame, and a driving motor is installed in the groove through a motor seat. A rotating gear is installed on the output shaft of the driving motor. The rotating gear meshes with an annular gear. The annular gear is installed in the middle of the outer side of the rotating frame. The inner side of the rotating frame is connected to the upper end of the inner sleeve through screws.

[0015] By adopting the above technical solution, the rotating unit drives the cyclone separation unit to rotate at high speed through the gear meshing method, so that the dust that has not been completely burned in the dust-containing gas can be accurately separated from the air flow.

[0016] Preferably, the filtering unit includes a filtering housing, filtering plates, and electric heating plates. The filtering housing is arranged in an open manner. Filtering plates are uniformly installed inside the filtering housing. Electric heating plates are arranged between adjacent filtering plates. The filtering plates and the electric heating plates are tightly stacked inside the filtering housing.

[0017] By adopting the above technical solution, the centrifuged gas enters the middle of the inner sleeve. The filter plate can perform secondary filtration on the gas to prevent impurities from overflowing due to incomplete separation of tiny particles. The electric heating plate can heat and burn the tiny particles to ensure that the discharged gas meets the requirements.

[0018] Preferably, the filter plate has a circular structure. The filter plate is made of heat-resistant ceramic material. Filter holes are uniformly arranged on the filter plate, and the filter holes on adjacent filter plates are staggered.

[0019] By adopting the above technical solution, the staggered filter holes can prevent the gas from passing directly through, thereby increasing the travel distance of the gas passing through. At the same time, the tiny particles in the gas can accurately contact the electric heating plate, so that the tiny particles can be effectively removed, and at the same time, the phenomenon of blockage caused by the accumulation of tiny particles can be prevented.

[0020] Preferably, the electric heating plate has a circular structure. The middle part of the electric heating plate is an electric heating wire. Insulating plugs and conductive plugs are respectively installed along the circumferential direction at the outer end of the electric heating plate. The insulating plugs and conductive plugs are arranged in a cross manner. Jacks matching with the insulating plugs and conductive plugs are arranged on the filter plate.

[0021] By adopting the above technical solution, adjacent conductive plugs are in contact with each other, so that adjacent electric heating plates are electrically connected to each other, which is convenient for the electric heating plate to be powered on and heated. At the same time, the insulating plugs and conductive plugs play a positioning role, so that the filter plate and the electric heating plate can be accurately installed and fixed.

[0022] Preferably, the discharge rack has a conical structure. A lining plate is installed on the inner side surface of the discharge rack, and the lining plate is detachably arranged.

[0023] By adopting the above technical solution, the lining plate plays a protective role, avoiding the phenomenon that the discharge rack is damaged due to the long-term action of centrifugal force on solid particles, and improving the service life of the discharge rack.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] In order to accurately achieve the function of centrifugally separating gases, a cyclone separation unit is provided in the present invention. The cyclone separation unit rotates at high speed, driving the flue gas generated by thermal power generation to rotate synchronously. The high-speed rotation of the flue gas generates centrifugal force, causing solid particles with greater inertial centrifugal force to be thrown towards the wall surface of the housing and separated, thereby achieving the function of solid-gas separation. In order to accurately drive the gas for secondary separation, in the present invention, the stirring blades are arranged in an inclined structure. When the stirring blades rotate at high speed, a negative pressure cavity is formed between adjacent stirring blades. When the gas enters the inner sleeve, the gas that has not completely passed through enters the negative pressure cavity again through the negative pressure holes. Under the rotational action of the stirring blades, the gas can undergo secondary centrifugal separation, improving the separation effect of the dust-containing gas. In order to increase the travel of the gas during filtration, in the present invention, filter holes are evenly provided on the filter plate, and the filter holes on adjacent filter plates are arranged in a staggered manner. The staggered filter holes can prevent the gas from passing directly through, thereby increasing the travel of the gas passing through. At the same time, the tiny particles in the gas can accurately contact the electric heating plate, enabling the tiny particles to be effectively removed, while also preventing the phenomenon of blockage caused by the accumulation of tiny particles. In order to accurately remove the tiny particles in the gas, in the present invention, the electric heating plate is arranged in a circular structure, and the middle part of the electric heating plate is an electric heating wire. Through the electric heating plate, the accumulated impurities can be accurately heated and burned, achieving both the effect of self-cleaning and preventing the phenomenon of impurity accumulation.

Detailed implementation manners

[0036] The following Figures 1-8 further describes the present application in detail.

[0037] The embodiment of the present application discloses a clean thermal power generation cyclone separator, which can accurately realize the function of filtering and separating the flue gas generated by thermal power generation.

[0038] Referring Figures 1-2 As shown, a clean thermal power generation cyclone separator includes a support frame 1, a cyclone separation module 2, an air inlet pipe 3 and a sealing end cover 4. The number of the support frames 1 is multiple. The cyclone separation module 2 is installed between the upper ends of the support frames 1. The air inlet pipe 3 is installed at the upper left side of the cyclone separation module 2. The sealing end cover 4 is detachably installed at the upper end of the cyclone separation module 2. The sealing end cover 4 is evenly provided with exhaust holes. The clean gas separated and filtered by the cyclone separation module 2 is discharged through the exhaust holes.

[0039] As Figures 2-8 shown, in order to accurately filter and clean the gas generated by thermal power generation, the cyclone separation module 2 is provided in this embodiment. The cyclone separation module 2 includes a housing frame 21, a cyclone separation unit 22, an annular frame 23, a rotating unit 24, a filtering unit 25 and a material discharging rack 26. The housing frame 21 has a cylindrical hollow structure. The cyclone separation unit 22 is arranged inside the housing frame 21. The lower end of the cyclone separation unit 22 is connected to the inner wall of the housing frame 21 through the annular frame 23. The upper end of the cyclone separation unit 22 is connected to the rotating unit 24. The rotating unit 24 is installed at the upper inner end of the housing frame 21. The middle part of the cyclone separation unit 22 has a hollow structure. The filtering unit 25 is installed at the upper inner end of the cyclone separation unit 22. The material discharging rack 26 is installed at the lower end of the housing frame 21. The material discharging rack 26 has a conical structure.

[0040] During actual use, the flue gas generated by thermal power generation enters the interior of the housing frame 21 through the intake pipe 3. The rotating unit 24 drives the gas to rotate at high speed through the cyclone separation unit 22. The high-speed rotation of the flue gas generates centrifugal force, causing solid particles with greater inertial centrifugal force to be thrown towards the wall surface of the housing frame 21 and separated, thereby achieving the function of solid-gas separation. The filtration unit 25 can secondarily filter the separated gas, and the separated impurities are discharged downward through the discharge frame 26.

[0041] Referring to Figures 4-5 , in order to accurately achieve the function of centrifugally separating gas, a cyclone separation unit 22 is provided in this embodiment. The cyclone separation unit 22 includes an inner sleeve 221, a connecting sleeve 222, and stirring blades 223. The inner sleeve 221 has a cylindrical hollow structure. A connecting sleeve 222 is installed at the lower end of the outer side of the inner sleeve 221. Card slots are uniformly provided on the outer side surface of the connecting sleeve 222, and stirring blades 223 are installed in the card slots.

[0042] During actual use, the rotating unit 24 drives the stirring blades 223 to rotate through the inner sleeve 221. The high-speed rotation of the stirring blades 223 drives the flue gas generated by thermal power generation to rotate synchronously. The high-speed rotation of the flue gas generates centrifugal force, causing solid particles with greater inertial centrifugal force to be thrown towards the wall surface of the housing frame 21 and separated, thereby achieving the function of solid-gas separation.

[0043] Referring to Figure 4 As shown, in order to accurately drive the gas for secondary separation, the stirring blades 223 are set in an inclined structure in this embodiment. A negative pressure chamber is provided between adjacent stirring blades 223. Negative pressure holes 224 are uniformly provided on the inner sleeve 221 and the connecting sleeve 222, and the negative pressure holes 224 are located between the negative pressure chambers.

[0044] During actual use, when the stirring blades 223 rotate at high speed, the gap between adjacent stirring blades 223 forms a negative pressure chamber. When the gas enters the interior of the inner sleeve 221, the gas that has not completely passed through enters the interior of the negative pressure chamber again through the negative pressure holes 224. Under the rotation of the stirring blades 223, the gas can be secondarily centrifugally separated, improving the separation effect of the dust-containing gas.

[0045] In order to prevent unfiltered gas from directly entering the interior of the inner sleeve 221 through the negative pressure holes 224, the cross-section of the negative pressure holes 224 is set in a conical structure in this embodiment, and the cross-sectional diameter of the negative pressure holes 224 gradually decreases from inside to outside.

[0046] During actual use, the outer diameter of the negative pressure holes 224 is smaller than the inner diameter, preventing gas from directly entering the interior of the inner sleeve 221 and ensuring the separation effect of the dust-containing gas.

[0047] Referring to Figure 5As shown in the figure, in order to enable the high-speed rotation of the cyclone separation unit 22, a rotating unit 24 is provided in this embodiment. The rotating unit 24 includes a fixed frame 241, a rotating frame 242, a driving motor 243, a rotating gear 244, and an annular gear 245. The fixed frame 241 is installed at the upper end inside the housing frame 21. The fixed frame 241 is an annular structure with a U-shaped cross-section. The rotating frame 242 is installed inside the fixed frame 241 through bearings. A groove is provided on the fixed frame 241, and the driving motor 243 is installed in the groove through a motor base. A rotating gear 244 is installed on the output shaft of the driving motor 243. The rotating gear 244 meshes with the annular gear 245. The annular gear 245 is installed in the middle of the outer side of the rotating frame 242. The inner side of the rotating frame 242 is connected to the upper end of the inner sleeve 221 by screws.

[0048] During actual use, the rotating unit 24 drives the cyclone separation unit 22 to rotate at a high speed through gear meshing, so that the unburned dust in the dust-containing gas can be accurately separated from the air flow.

[0049] Refer to Figures 5-7 As shown in the figure, in order to be able to accurately remove the tiny particles in the gas, a filtering unit 25 is provided in this embodiment. The filtering unit 25 includes a filtering housing 251, a filtering plate 252, and an electric heating plate 253. The filtering housing 251 is provided in an open form. The filtering plates 252 are evenly installed inside the filtering housing 251. An electric heating plate 253 is provided between adjacent filtering plates 252. The filtering plates 252 and the electric heating plates 253 are closely stacked inside the filtering housing 251.

[0050] During actual use, the gas after centrifugation enters the middle of the inner sleeve 221. The filtering plate 252 can perform secondary filtration on the gas to prevent the incomplete separation of tiny particles from causing impurities to overflow. The electric heating plate 253 can heat and burn the tiny particles to ensure that the discharged gas meets the requirements.

[0051] Refer to Figure 6 As shown in the figure, in order to be able to increase the travel of the gas during filtration, in this embodiment, the filtering plate 252 is set to be a circular structure. The filtering plate 252 is made of heat-resistant ceramic material. Filter holes are evenly provided on the filtering plate 252. The filter holes on adjacent filtering plates 252 are staggered.

[0052] During actual use, the staggered filter holes can prevent the gas from passing directly, thereby increasing the travel of the gas passing through. At the same time, the tiny particles in the gas can accurately contact the electric heating plate 253, so that the tiny particles can be effectively removed, and at the same time, it can prevent the accumulation of tiny particles from causing blockage.

[0053] Refer to Figure 7As shown, in order to accurately remove the tiny particles in the gas, in this embodiment, the electric heating plate 253 is arranged in a circular structure. The middle part of the electric heating plate 253 is an electric heating wire. Along the circumferential direction of the outer end of the electric heating plate 253, an insulating plug 254 and a conductive plug 255 are respectively installed. The insulating plug 254 and the conductive plug 255 are arranged in a cross manner. On the filter plate 252, there are jacks 256 that cooperate with the insulating plug 254 and the conductive plug 255.

[0054] During the actual use process, adjacent conductive plugs 255 are in contact with each other, making adjacent electric heating plates 253 electrically connected to each other, which is convenient for the electric heating of the electric heating plates 253. At the same time, the insulating plug 254 and the conductive plug 255 play a positioning role, enabling the accurate installation and fixation between the filter plate 252 and the electric heating plate 253.

[0055] It should be noted that the electric heating plate 253 may not be powered on during normal operation. When tiny particles accumulate in the gap between the filter plate 252 and the electric heating plate 253, the high-temperature gas generated by thermal power generation can effectively remove the tiny particles, thereby achieving the effect of saving resources. When the temperature of the introduced gas is relatively low or the gas discharge efficiency is relatively low, the electric heating plate 253 can accurately heat and burn the accumulated impurities, which can not only achieve the self-cleaning effect but also prevent the phenomenon of impurity accumulation.

[0056] It should be noted that the filter plate 252 and the electric heating plate 253 are detachably arranged. When the tiny particles in the gas are not heated in time or there is still a phenomenon of accumulation after heating, the filter plate 252 and the electric heating plate 253 are disassembled and cleaned to achieve the function of accurate flue gas filtration.

[0057] Refer to Figure 8 As shown, in order to prevent the discharge rack 26 from being damaged after long-term use, in this embodiment, the discharge rack 26 is arranged in a conical structure. An inner lining plate 261 is installed on the inner side surface of the discharge rack 26, and the inner lining plate 261 is detachably arranged.

[0058] During the actual use process, the inner lining plate 261 plays a protective role, avoiding the phenomenon that the discharge rack 26 is damaged due to the long-term action of centrifugal force on solid particles, and improving the service life of the discharge rack 26.

[0059] It should be noted that the lower end of the discharge rack 26 is connected to the spiral collection rack. The spiral collection rack can effectively transport the collected solid particles downward, avoiding the phenomenon of solid particle accumulation. At the same time, a scraper is arranged on the surface of the inner lining plate 261, and the scraper is connected to the spiral collection rack. The scraper can effectively scrape the raw materials adhered to the inner lining plate 261.

[0060] The implementation principle of this embodiment is:

[0061] 1: Flue gas inlet. The high-temperature flue gas generated by thermal power generation is introduced into the interior of the housing frame 21 through the intake pipe 3.

[0062] 2: Centrifugal separation. The rotating unit 24 drives the gas to rotate at high speed through the cyclone separation unit 22. The high-speed rotation of the flue gas generates centrifugal force, causing solid particles with greater inertial centrifugal force to be thrown towards the wall surface of the housing frame 21 and separated, thereby achieving the function of solid-gas separation.

[0063] 3: Filtration and cleaning. The gas after centrifugation enters the middle of the inner sleeve 221. The filter plate 252 can perform secondary filtration on the gas to prevent incomplete separation of tiny particles from causing impurity overflow. The electric heating plate 253 can heat and burn the tiny particles to ensure that the discharged gas meets the requirements.

[0064] 4: Waste collection. The solid particles after centrifugal separation are discharged downward through the discharge rack 26 to avoid the phenomenon of solid particle accumulation.

[0065] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
