Description

Technical Field

[0001] The invention relates to the technical field of gas-solid separation processing, and in particular to a gas-solid separator used in flue gas processing. Background Art

[0002] Waste incineration is the process of reducing the volume of waste through oxidation at high temperature through appropriate thermal decomposition, combustion, melting and other reactions, and turning it into residue or molten solid matter. Waste incineration facilities must be equipped with flue gas treatment facilities to prevent heavy metals, organic pollutants, etc. from being discharged into the environmental medium again. Recycling the heat generated by waste incineration can achieve the purpose of waste resource utilization; in the process of waste incineration, a large amount of flue gas will be generated, and the flue gas contains a large amount of solid particles, which will cause air pollution when directly discharged into the air, so it is necessary to separate the flue gas from the solid.

[0003] In the prior art, negative pressure is generated on the upper part of the gas-solid separation filter device through a circulating fan. Under the adsorption of negative pressure, the flue gas is transported through the intervals between two adjacent blades to filter the flue gas. At the same time, the rotation of the blades can scrape off the impurity particles attached to the surfaces of the first screen and the second screen, and the impurities fall off by themselves due to their own gravity, which can effectively remove the solid impurities carried in the conveying gas and achieve gas-solid separation. At the same time, the filter has the advantages of high filtration rate, light equipment, small footprint, flexible configuration, automatic cleaning, wind locking, etc.; however, during use, when the scraper scrapes off the impurity particles attached to the surface of the first screen, the impurity particles are continuously accumulated on one side of the scraper. Due to the thrust of the scraper on the impurity particles, the impurity particles will fit closely to each other, and the impurity particles will fit closely to the scraper, resulting in the impurity particles not being able to be removed when they are located above the discharge port. It can fall by its own gravity, such as a gas-solid separation filter provided by authorization announcement number CN110124399B. The air outlet pipe is connected to the air inlet of the circulating fan to generate negative pressure on the upper part of the gas-solid separation filter device. The feed bin transports air and impurity particles or materials to the inside of the gas-solid separator through a pipeline, and disperses them on the blades and between two adjacent blades. Under the action of the driving device, the rotation of the rotating shaft drives the rotating drum to rotate, and then drives the blades to rotate, so that the air and impurity particles on the blades or between two adjacent blades are driven to move downward, and the air flows through the mesh holes in the first screen or the second screen through the air flow channel and is discharged from the air outlet pipe to the circulating fan, and the impurity particles or materials can be discharged from the lower pressure-free discharge port driven by the blades. It is convenient and fast, and has high separation efficiency, and is suitable for the effective removal of large particle impurities.

[0004] It has a major disadvantage: when the scraper scrapes off the impurity particles attached to the surface of the first screen, the impurity particles continue to accumulate on one side of the scraper. Due to the thrust of the scraper on the impurity particles, the impurity particles and the scraper will fit tightly, resulting in the impurity particles being unable to fall by their own gravity when located above the discharge port. Summary of the invention

[0005] The embodiment of the present application provides a gas-solid separator for flue gas treatment, which solves the problem in the prior art that when the scraper scrapes off the impurity particles attached to the surface of the first screen, the impurity particles are continuously accumulated on one side of the scraper. Due to the thrust of the scraper on the impurity particles, the impurity particles are tightly fitted to each other and to the scraper, resulting in the impurity particles being unable to fall off by their own gravity when they are located above the discharge port. When the scraper rotates to the position of the impact rod, a certain impact force is generated, thereby effectively shaking off the dust attached to the scraper to prevent affecting the working efficiency of the scraper; the gas-solid separation efficiency is improved, ensuring that the scraper is always kept clean, and ensuring the ability of the scraper to scrape off solid impurities on the filter screen, the scraper can better contact with the filter screen and scrape off more impurities, thereby improving the efficiency of the entire gas-solid separation process; the service life of the equipment is extended, and the dust on the scraper can be shaken off in time by the impact rod, which can reduce the wear on the scraper and the filter screen and extend the service life of the equipment; easy operation and convenient maintenance: the design of the impact rod is simple and practical, and does not require complicated installation and maintenance processes, and does not require manual intervention, thereby reducing the difficulty of operation and maintenance costs.

[0043] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0044] First, it can better remove solid impurities on the scraper. When the scraper rotates to the impact rod position, a certain impact force will be generated, thereby effectively shaking off the dust attached to the scraper to prevent affecting the working efficiency of the scraper; improve the efficiency of gas-solid separation, ensure that the scraper is always kept clean, and ensure the ability of the scraper to scrape off solid impurities on the filter. The scraper can better contact with the filter and scrape off more impurities, thereby improving the efficiency of the entire gas-solid separation process; extend the service life of the equipment. The impact rod can timely shake off the dust on the scraper, which can reduce the wear on the scraper and the filter and extend the service life of the equipment; easy operation and convenient maintenance: The design of the impact rod is simple and practical, without complicated installation and maintenance processes, and no manual intervention, which reduces the difficulty of operation and maintenance costs;

[0045] Secondly, by forming a separate space that is not connected to the negative pressure space generated by the fan exhaust, the shaken solid impurities can fall by themselves by their own gravity, thereby improving the cleaning efficiency of the solid impurities and effectively preventing the shaken solid impurities from being unable to be discharged due to negative pressure and returning to the filter shell again. At the same time, during the rotation of the scraper, the magnet at one end of the scraper fits tightly with the filter screen to prevent the scraper from not fitting with the filter screen due to the centrifugal force.

[0046] Third, it enhances the dust cleaning effect. When the scraper hits the impact rod, the air inside the scraper is squeezed and discharged from the air outlet, generating an airflow. This airflow can blow the shaken solid impurities and make them fall down quickly, preventing the re-generation of negative pressure, which will adsorb the solid impurities again and make them adhere to the scraper or filter net, thereby enhancing the solid impurity cleaning effect and improving the efficiency of gas-solid separation; it reduces the wear of the scraper and the impact rod. The hollow interior of the scraper can produce a buffering effect, reducing the direct impact force between the scraper and the impact rod, reducing the wear between the two, extending the service life, and reducing the heat generated by friction, further protecting the stability of the equipment;

[0047] Fourthly, the fit between the scraper and the impact rod is enhanced. Through the attraction of the magnet, the scraper can fit more closely on the impact rod, ensuring that every part of the scraper can be effectively cleaned; effectively scrape off sticky solid impurities. The corner design on one side of the impact rod can carry out targeted scraping of sticky solid impurities on the scraper. Due to the sharpness of the corner, it is easier to scrape solid impurities off the scraper. At the same time, the detachable setting of the impact rod and the filter can increase the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The smoke generated by the incineration enters the filter housing 110 through the air inlet 120. During the process of filtering the smoke, the fan 130 works to extract the gas in the groove 111, the groove 2 112 and the storage tank 114, so that negative pressure is generated inside. The drum 140 drives the rotating rod 150 and the scraper 210 to rotate, and the smoke is stored and transported in the interval between two adjacent rotating rods 150. When the two adjacent rotating rods 150 storing the smoke rotate to the position of the filter screen 190, the fan 130 extracts the internal smoke, and the smoke passes through the filter screen 1 90 is filtered and then discharged. During the filtering process, one end of the scraper 210 is pressed against the filter screen 190 during the rotation process to scrape off the solids remaining on the surface of the filter screen 190 after filtering. When the scraper 210 rotates to the impact rod 220 position, it impacts the impact rod 220. The force generated by the impact shakes off the solid impurities attached to the surface of the scraper 210. At the same time, the rotation speed of the motor 180 can be controlled. When the scraper 210 impacts the impact rod 220, it stops rotating for 2-3 seconds, and then rotates again, working in this reciprocating manner.

[0060] Embodiment 1: Figure 1-Figure 2 As shown, the present application provides a gas-solid separator for flue gas treatment, comprising a filter assembly 100;

[0061] The filter assembly 100 includes a filter housing 110, a groove 111, a storage tank 114, a rotating drum 140 and a rotating rod 150;

[0062] The filter housing 110 has a groove 111 on one side, and a storage groove 114 is provided on the inner bottom side of the groove 111. The rotating drum 140 is cylindrical, and the straight line of the rotating drum 140 is parallel to the ground. The rotating drum 140 is located in the groove 111 and the storage groove 114, and one end of the axis of the rotating drum 140 is rotatably connected to the end away from the opening of the groove 111;

[0064] Also included is a cleaning assembly 200, wherein the cleaning assembly 200 includes a scraper 210 and an impact rod 220;

[0065] The number of the scrapers 210 is the same as the number of the rotating rods 150, and they correspond one to one. The scrapers 210 are rectangular, and the length direction of the scrapers 210 is consistent with the length direction of the rotating rods 150. The scrapers 210 are fixed to one end of the rotating rods 150 away from the rotating drum 140.

[0066] The impact rod 220 is located in the storage groove 114, the impact rod 220 is located at the lower side of the drum 140, and one end of the impact rod 220 is arranged at an end away from the opening of the groove 111;

[0067] When the rotating drum 140 drives the rotating rod 150 and the scraper 210 to rotate, the scraper 210 may impact on the impact rod 220;

[0068] The scraper 210 is made of silicone rubber;

[0069] The filter assembly 100 further includes a groove 112, a feed port 113, an air inlet 120, a fan 130, a support leg 160, a disassembly plate 170, a motor 180 and a filter screen 190;

[0070] The groove 111 is in a rectangular shape, the length direction of the groove 111 is parallel to the axial direction of the drum 140, and the length of the groove 111 is consistent with the length of the drum 140;

[0071] The storage slot 114 has two grooves 112 on both sides. The storage slot 114 and the groove 112 are both arc-shaped. The axis of the storage slot 114 and the axis of the drum 140 are on the same straight line. The axis of the groove 112 is parallel to the axis of the storage slot 114.

[0072] The length of the storage slot 114 is consistent with the length of the drum 140, and the length of the second groove 112 is less than the length of the storage slot 114;

[0073] The number of the filter screens 190 is consistent with the number of the second grooves 112, and they correspond one to one. The filter screens 190 are arc-shaped, and the axis of the filter screens 190 is parallel to the axis of the second groove 112. The length of the filter screens 190 is consistent with the length of the second groove 112. The filter screens 190 are arranged in the second groove 112, and the filter screens 190 separate the second groove 112 and the storage tank 114 into two separate spaces.

[0074] When the rotating drum 140 drives the rotating rod 150 and the scraper 210 to rotate, the scraper 210 is closely attached to the filter screen 190;

[0075] The storage tank 114 has a discharge port 113 at its bottom. The discharge port 113 is in a rectangular shape. The length of the discharge port 113 is parallel to the axis of the drum 140 . The length of the discharge port 113 is consistent with the length of the scraper 210 .

[0076] The ends of the rotating drum 140, the second groove 112 and the discharge port 113 that are open toward the first groove 111 are all arranged to penetrate one end of the filter housing 110;

[0077] The filter housing 110 has an air inlet 120 on its upper side. The number of the fans 130 is the same as the number of the second grooves 112 and they correspond one to one. The fans 130 are fixed on one side of the filter housing 110, and the input end of the fans 130 is connected to the second groove 112.

[0078] The support legs 160 are fixed to the lower side of the filter housing 110;

[0079] The disassembly plate 170 is detachably disposed on one side of the filter housing 110 with the four openings of the groove 111, the groove 2 112, the material discharge port 113 and the storage slot 114, and the disassembly plate 170 blocks one end of the groove 111, the groove 2 112, the material discharge port 113 and the storage slot 114;

[0080] The motor 180 is fixed to one side of the filter housing 110 , and the output end of the motor 180 is fixed to one end of the rotating drum 140 that is rotatably connected to the groove 111 .

[0081] When in use, the smoke generated by incineration enters the filter housing 110 through the air inlet 120. In the process of filtering the smoke, the fan 130 works to extract the gas in the groove 111, the groove 2 112 and the storage tank 114, so that negative pressure is generated inside. The rotating drum 140 drives the rotating rod 150 and the scraper 210 to rotate, and the smoke is stored and transported in the gap between two adjacent rotating rods 150. When the two adjacent rotating rods 150 storing the smoke rotate to the position of the filter screen 190, the fan 130 extracts the internal smoke, and the smoke passes through The filter screen 190 is discharged after filtering. During the filtering process, one end of the scraper 210 is pressed against the filter screen 190 during rotation to scrape off the solids remaining on the surface of the filter screen 190 after filtering. When the scraper 210 rotates to the position of the impact rod 220, it impacts the impact rod 220. The force generated by the impact shakes off the solid impurities attached to the surface of the scraper 210. At the same time, the rotation speed of the motor 180 can be controlled. When the scraper 210 impacts the impact rod 220, it stops rotating for 2-3 seconds, and then rotates again, working in this reciprocating manner.

[0082] Compared with the prior art, the solid impurities on the scraper 210 can be better removed. When the scraper 210 rotates to the position of the impact rod 220, a certain impact force will be generated, thereby effectively shaking off the dust attached to the scraper 210 to prevent affecting the working efficiency of the scraper 210; improving the gas-solid separation efficiency, ensuring that the scraper 210 is always kept clean, and ensuring the ability of the scraper 210 to scrape off the solid impurities on the filter 190. The scraper 210 can better contact with the filter 190 and scrape off more impurities, thereby improving the efficiency of the entire gas-solid separation process; extending the service life of the equipment. By using the impact rod 220 to timely shake off the dust on the scraper 210, the wear on the scraper 210 and the filter 190 can be reduced, thereby extending the service life of the equipment; easy operation and convenient maintenance: the design of the impact rod 220 is simple and practical, does not require complicated installation and maintenance processes, and does not require manual intervention, which reduces the difficulty of operation and maintenance costs.

[0083] Embodiment 2: When the embodiment 1 is in use, the scraper 210 hits the impact rod 220, so that the solid impurities attached to its surface are shaken off. However, during use, due to the negative pressure generated inside, the solid impurities cannot fall off by gravity during the shaking process, and the dust is adsorbed into the groove 111, the groove 2 112 and the storage groove 114, resulting in a poor cleaning effect. At the same time, during the rotation of the scraper 210, the rubber scraper 210 will be affected by the centrifugal force, resulting in it being unable to cling to the filter screen 190. Based on this, the solution of the embodiment 1 is improved, such as Figure 3 As shown:

[0084] There is a gap between the filter screen 190 and the feed opening 113;

[0085] There are three scrapers 210 on the rotating drum 140 in sequence. When the ends of two non-adjacent scrapers 210 away from the rotating drum 140 are located on both sides of the discharge port 113 and abut against the interval between the filter screen 190 and the discharge port 113, the scraper 210 located in the middle hits the impact rod 220. When the scraper 210 located in the middle finishes colliding with the impact rod 220 and does not contact the impact rod 220, the scraper 210 located in the front of the rotation contacts the filter screen 190 in the front of the rotation.

[0086] The filter screen 190 is made of magnetic material, and a magnet is fixed inside one end of the scraper 210 away from the rotating rod 150 .

[0087] During the rotation of the scraper 210, one end of the scraper 210 is adsorbed on the filter 190 by a magnet to fix its position. When two non-adjacent scrapers 210 among three scrapers 210 are counted in sequence, they respectively abut on both sides of the discharge port 113 and are not in contact with the filter 190. The space formed by the two non-adjacent scrapers 210 and the discharge port 113 is not affected by the negative pressure generated by the exhaust of the fan 130. The scraper 210 in the middle of the three scrapers 210 hits the impact rod 220 to shake off the solid impurities.

[0088] By forming a separate space which is not connected to the negative pressure space generated by the exhaust of the fan 130, the shaken-off solid impurities can fall by their own gravity, thereby improving the cleaning efficiency of the solid impurities and effectively preventing the shaken-off solid impurities from being unable to be discharged due to negative pressure and returning to the filter shell 110. At the same time, during the rotation of the scraper 210, the magnet at one end of the scraper 210 fits tightly against the filter screen 190, preventing the scraper 210 from not fitting against the filter screen 190 due to the action of centrifugal force.

[0089] Embodiment 3: When the second embodiment is in use, by changing the position of the filter screen 190, the scraper 210 can form a space that is not connected to the negative pressure space when it hits the impact rod 220, so as to facilitate dust discharge. However, during use, when the scraper 210 rotates, the space that is not connected to the space is intermittently generated. When the scraper 210 rotates again, the two will be reconnected, and the negative pressure will again suck up the solid impurities floating in the discharge port 113 and make them enter the filter shell 110. Based on this, the solution of the second embodiment is improved, such as Figure 4-Figure 5 As shown:

[0090] The cleaning assembly 200 further includes an air outlet 211, a blocking member and a one-way valve 240;

[0091] The drum 140 rotates clockwise, and the scraper 210 is hollow inside;

[0092] The air outlet 211 is cylindrical, and the front side of the scraper 210 in the rotation direction is provided with the air outlet 211, and the air outlet 211 is connected with the inner hollow space of the scraper 210, and the air outlet 211 is located at one end of the scraper 210 away from the rotating rod 150;

[0093] There are multiple air outlets 211, which are evenly spaced and distributed along the axis of the drum 140;

[0094] The number of the blocking pieces is consistent with the number of the air outlets 211 and corresponds one to one. The blocking pieces are cylindrical and fixed in the air outlets 211.

[0095] The blocking member includes two baffles 230, which are symmetrically arranged along the length direction of the axis of the air outlet 211, and the two baffles 230 are closely fitted to each other on one side thereof, and the baffles 230 are made of silicone rubber;

[0096] A one-way valve 240 is fixed to the rear of the scraper 210 in the rotation direction, and the one-way valve 240 only allows external air to enter the scraper 210 .

[0097] When in use, when the scraper 210 rotates and hits the impact rod 220, the scraper 210 is squeezed, and the gas stored inside is discharged through the air outlet 211, and the shaken solid impurities are quickly blown down, so that the area of ​​the material support discharge port 113 can rely on its own elasticity to restore to its original state when the scraper 210 is not squeezed by the impact rod 220. At the same time, new gas is injected into the inside through the one-way valve 240 to restore it to its original state.

[0098] Enhance the dust cleaning effect. When the scraper 210 hits the impact rod 220, the air inside the scraper 210 is squeezed and discharged from the air outlet 211, generating an airflow. This airflow can blow the shaken solid impurities to make them fall down quickly, preventing the re-generation of negative pressure, and re-adsorbing the solid impurities to make them adhere to the scraper 210 or the filter 190, thereby enhancing the solid impurity cleaning effect and improving the efficiency of gas-solid separation; reduce the wear of the scraper 210 and the impact rod 220. The interior of the scraper 210 is hollow and can produce a buffering effect, reducing the direct impact force between the scraper 210 and the impact rod 220, reducing the wear between the two, extending the service life, and reducing the heat generated by friction, further protecting the stability of the equipment.

[0099] Embodiment 4: When the third embodiment is in use, the scraper 210 scrapes off the solid impurities attached to the surface of the filter screen 190. When the generated smoke is oil smoke, the solid impurities attached to the surface of the scraper 210 are difficult to remove. The solid impurities will adhere to one side of the scraper 210. The scraper 210 alone is difficult to remove the solid impurities by impacting the impact rod 220. Based on this, the third embodiment is improved, such as Figure 6 As shown:

[0100] The cross section of the impact rod 220 is an isosceles trapezoid, and the impact rod 220 is made of magnetic material;

[0101] The filter screen 190 is detachably disposed in the second groove 112 .

[0102] When in use, when the scraper 210 impacts the impact rod 220 after scraping off the solid impurities generated by the oil smoke, the magnet at one end of the scraper 210 attracts the impact rod 220, so that the scraper 210 can be close to the impact rod 220, and the position of the scraper 210 is restricted. During the rotation of the scraper 210, the solid impurities attached to one side of the scraper 210 are scraped off through the angle of one side of the impact rod 220. At the same time, after long-term use, the disassembly plate 170 can be removed to clean the internal filter 190 and the oily solid impurities attached to the surface of the impact rod 220. When scraping off the oily solid impurities, the gas sprayed from the air outlet 211 can blow to assist in the removal of the solid impurities.

[0103] Enhance the fit between the scraper 210 and the impact rod 220. Through the attraction of the magnet, the scraper 210 can fit more closely on the impact rod 220, ensuring that every part of the scraper 210 can be effectively cleaned; effectively scrape off sticky solid impurities. The corner design on one side of the impact rod 220 can perform targeted scraping of sticky solid impurities on the scraper 210. Due to the sharpness of the corner, it is easier to scrape solid impurities off the scraper 210. At the same time, the detachable setting of the impact rod 220 and the filter 190 can increase the service life of the equipment.

[0104] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
