[0036] Please refer to Figures 1-4, A biomass gas ash and coke removal purification device, including a purification box 1. A collection bin 2 is installed at the lower end of the purification box 1. A sealing door panel 3 is movably connected to the side end of the purification box 1. A plurality of support columns 4 are fixedly connected to the lower end of the collection bin 2. A partition 5 is fixedly connected between the inner walls of the purification box 1. A positioning member is installed at the upper end of the partition 5. A first purification component 6 is installed between the inner walls of the positioning member. A second purification component 7 is installed at the upper end of one side of the purification box 1. An intake pipe 8 is embedded and installed at the right end of the purification box 1. An outlet pipe 9 is embedded and installed at the left end of the purification box 1.
[0037] During the use of this solution, to avoid the blockage and corrosion of pipelines caused by tar and dust in existing biomass gas, which affect the stable operation of related combustion equipment. In this embodiment, when the biomass gas is transported into the interior of the purification box 1 through the intake pipe 8, it first comes into contact with the water body and gas sprayed by the second purification component 7, so that the tar mist particles in the gas come into contact with the surface of the packing and are adsorbed on the surface of the packing. After reaching a certain volume, they drip down, thus achieving the removal of the tar content in the biomass gas.
[0038] And during this period, the water body also wets the dust contained in the biomass gas, increasing the weight of the dust content and its adhesion to other objects. At the same time, under the continuous spraying of the water body by the second purification component 7, the gas humidity inside the purification box 1 also increases greatly, so that part of the water mist adheres to the surface of the first purification component 6, which is conducive to the treatment of the dust in the biomass gas.
[0039] Then the preliminarily treated biomass gas passes through the first purification component 6, further removing the tar content in the biomass gas and blocking the dust in the biomass gas, so that the clean biomass gas is discharged through the outlet pipe 9.
[0040] During the purification of the biomass gas in this solution, the purified tar and dust can gradually fall into the collection bin 2 for discharge treatment.
[0041] Subsequent personnel can open the sealing door panel 3 and remove the positioning members fixing the outside of the first purification component 6, so as to disassemble the first purification components 6 one by one and complete the replacement and cleaning work.
[0042] Please refer to Figures 1-2 , a first purification chamber 11 and a second purification chamber 12 that are interconnected are provided inside the purification box 1. An intake port 13 is provided at the right end of the purification box 1. An outlet port 14 is provided at the left end of the purification box 1. The partition 5 is located between the inner walls of the second purification chamber 12. The outlet port 14 is communicated with the outlet pipe 9. The intake port 13 is communicated with the intake pipe 8.
[0043] During the use of this solution, two built-in chambers with different functions are provided inside the purification box 1. The second purification chamber 12 serves as the ash and tar removal chamber for the biomass gas and also as the chamber for transporting the clean gas after purification of the biomass gas from the air outlet 14 into the outlet pipeline 9. The first purification chamber 11 serves as the chamber for transporting the air of the biomass gas and preliminarily treating its dust and tar. The air inlet 13 on one side is connected to the inlet pipeline 8 for transporting the biomass gas.
[0044] Please refer to Figures 1-3 , the positioning member includes a plurality of bases 51 fixedly connected to the upper end of the partition plate 5. The upper end of the base 51 is fixedly connected with an adapter cylinder 52. A threaded groove 53 is provided on the side end of the adapter cylinder 52. The upper end of the adapter cylinder 52 is fixedly connected with a plurality of positioning blocks 54 made of flexible materials. The outer end of the threaded groove 53 is threadedly connected with a positioning sleeve 55. The upper end of the positioning sleeve 55 is fixedly connected with a conical limiting sleeve 56. The first purification component 6 is located between the inner walls of the adapter cylinder 52.
[0045] Please refer to Figures 1-4 , the first purification component 6 includes a purification cylinder 61 provided between the inner walls of the positioning member. A filter cloth 62 is embedded and installed on the outer end of the purification cylinder 61. A cylindrical nickel-based catalyst 63 is filled between the inner walls of the purification cylinder 61.
[0046] During the use of this solution, the operator can initially pass a plurality of first purification components 6 through the lower side of the partition plate 5 and into the space between the inner walls of the adapter cylinder 52 respectively. Then, the positioning sleeve 55 is sleeved from the outside of the first purification component 6 and screwed onto the surface of the threaded groove 53. As the positioning sleeve 55 moves downward continuously, due to the continuously decreasing inner diameter of the conical limiting sleeve 56 above it, the originally vertically arranged positioning blocks 54 can be forced to contract continuously due to the pressing force, so that the plurality of positioning blocks 54 are inclined and fit against the surface of the first purification component 6, thereby clamping and positioning the first purification component 6 between the inner walls of the adapter cylinder 52. This can be used for subsequent purification of dust and tar in the biomass gas, and is also conducive to subsequent disassembly by the operator for cleaning and replacement steps;
[0047] At the same time, when the biomass gas enters the second purification chamber 12, due to the blockage of the partition plate 5, the biomass gas can only pass through the filter cloth 62 and contact and react with the cylindrical nickel-based catalyst 63 to purify the dust and tar in the biomass gas, and the clean gas is transported into the outlet pipeline 9 through the upper side of the purification cylinder 61;
[0048] During this period, due to the action of the purification component two 7 spraying water and gas into the interior of the purification tank 1, a large amount of water vapor also adheres to the surface of the purification cylinder 61. So that when the biomass gas passes through the filter cloth 62 subsequently, the dust inside it can adhere to the surface of the filter cloth 62 more efficiently. The cylindrical nickel-based catalyst 63 can effectively remove the tar in the biomass gas. Due to the water vapor adhering to the surface of the filter cloth 62, and the different densities of water and tar, after the tar mist particles come into contact with the surface of the dust, they can also be adsorbed on the surface of the dust, and after reaching a certain volume, they will drip down along the filter cloth 62. This greatly avoids the phenomenon of low purification effect due to excessive dust adhering to the surface of the filter cloth 62, and at the same time slows down the cycle of personnel replacing and cleaning the purification component one 6.
[0049] Please refer to Figures 1-2 , the purification component two 7 includes a pedestal 71 fixedly connected to the upper end of one side of the purification tank 1. A water tank 72 and an air pump 73 are installed on the upper end of the pedestal 71. A water body spray head 74 is installed at the lower end of the water tank 72. A gas spray head 75 is installed at the lower end of the air pump 73. The water body spray head 74 and the gas spray head 75 are both installed through to the interior of the purification tank 1.
[0050] During the use of this solution, when the biomass gas is transported into the interior of the purification chamber one 11, the water body spray head 74 and the gas spray head 75, under the action of the water tank 72 and the air pump 73, carry out gas contact by spraying water and gas, use adsorption and the condensation of tar itself to remove the tar content, and attach water vapor to the dust therein to enhance the subsequent dust cleaning efficiency.
[0051] Please refer to Figure 2 , a plurality of traction ropes 10 are fixedly connected to the inner wall of one side of the purification chamber one 11.
[0052] During the use of this solution, the traction ropes 10 swing randomly under the blowing of the air flow of the purification component two 7. Thus, under the mechanical swing, the tar particles of the biomass gas collide, and then condense into larger particles and fall off to be removed, enhancing the purification efficiency of the biomass gas.
[0053] The above-described embodiments only represent a certain implementation manner of the present invention. The description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the patent of the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention; therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
