Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device for non-edible vegetable oil processing. Background Technology

[0002] During the industrial production and processing of non-edible vegetable oils, waste gases such as nitrogen oxides are generated. These waste gases are usually passed into a treatment liquid for chemical treatment.

[0003] Chinese patent CN214680899U discloses a waste gas treatment device for non-edible vegetable oil processing, including a reaction tank. A feed inlet is fixedly connected to the top of the outer surface of the reaction tank, and an outlet pipe is fixedly connected to one side of the top surface of the reaction tank. An electric valve is fixedly connected to one end of the outer surface of the outlet pipe, and a cooling pipe is fixedly connected to the end of the electric valve away from the outer surface of the outlet pipe. A storage pipe is fixedly connected to the bottom end of the outer surface of the cooling pipe.

[0004] In existing technologies, when waste gas is introduced into a chemical treatment liquid, the continuous introduction of waste gas often causes large bubbles to form in the treatment liquid and overflow upwards. This results in some waste gas escaping without contacting the treatment liquid, which affects the treatment effect of the waste gas. Summary of the Invention

[0005] Based on the technical problems in the background art, the present invention proposes a waste gas treatment device for non-edible vegetable oil processing.

[0006] This invention proposes a waste gas treatment device for non-edible vegetable oil processing, comprising a treatment tank filled with a treatment liquid, an inlet pipe connected to the lower end of the treatment tank, and an outlet pipe connected to the upper end of the treatment tank. A dispersion cylinder rotating along a horizontal axis is installed inside the treatment tank, with a motor connected to the end of the dispersion cylinder. Multiple dispersion holes are formed on the outside of the dispersion cylinder, and a fixedly installed separator is installed inside the dispersion cylinder. The two sides of the separator slide in contact with the inner wall of the dispersion cylinder. The inlet pipe is located below the separator, and the outlet pipe is located above the dispersion cylinder. The treatment liquid in the treatment tank fills to the top of the separator. During use, the dispersion cylinder is reciprocated and rotated in different directions by the motor.

[0007] Preferably, a plurality of dispersing components are fixed inside the dispersing cylinder, the dispersing components extend radially in the dispersing cylinder, and the separator is provided with a partition plate fixed to the processing tank, and movable plates are rotatably connected to both sides of the partition plate by torsion springs.

[0008] Preferably, the dispersing component is installed at the distribution position of the dispersing holes, the dispersing component is configured as a box structure, and the end of the dispersing component facing the inner wall of the dispersing cylinder is open, while the end of the dispersing component away from the inner wall of the dispersing cylinder has multiple through holes.

[0009] Preferably, multiple vertical dispersing components are installed on both sides of the treatment tank. The multiple vertical dispersing components located on one side of the treatment tank are distributed at equal distances in the horizontal direction, and the vertical dispersing components have a portion that moves in the vertical direction as the dispersing cylinder rotates.

[0010] Preferably, the vertical disassembly component is provided with two vertically extending guide rails, and two disassembly structures are slidably connected between the two guide rails, with a spring connecting the two disassembly structures.

[0014] Preferably, the outer wall of the dispersion cylinder is provided with multiple grooves, and multiple magnetic blocks installed in the grooves are provided outside the dispersion cylinder.

[0015] The beneficial effects of this invention are as follows: In this invention, the continuously introduced waste gas is guided to both sides and dispersed by the alternating rotation of the dispersion cylinder and the obstruction of the separator.

[0019] Example 1: Refer to Figures 1-5A waste gas treatment device for non-edible vegetable oil processing includes a treatment tank 1 with an open top and a tank cover 101 installed on the top of the treatment tank 1. The treatment tank 1 is filled with a treatment liquid. A drain pipe 2 is connected to the bottom of one side of the treatment tank 1. An air inlet pipe 3 is connected to the lower end of the treatment tank 1. An air outlet pipe 4 is connected to the top of the treatment tank 1 and is installed on the tank cover 101. A dispersion cylinder 5 that rotates along a horizontal axis is provided inside the treatment tank 1. A motor 6 is connected to the end of the dispersion cylinder 5. One end of the dispersion cylinder 5 is sealed, and the other end of the dispersion cylinder 5 is open. The center of the sealed end of the dispersion cylinder 5 is fixedly connected to the output shaft of the motor 6. Multiple sets of dispersion holes 501 are opened on the outside of the dispersion cylinder 5. A separator is fixedly installed inside the dispersion cylinder 5. The separator is horizontally placed, and its two sides slide in contact with the inner wall of the dispersion cylinder 5. The air inlet pipe 3... The dispersing cylinder 5 is connected to the open end, and the inlet pipe 3 is located below the separator. The outlet pipe 4 is located above the top outer wall of the dispersing cylinder 5. The treatment liquid in the treatment tank 1 fills to the top of the separator. During use, the dispersing cylinder 5 is controlled by the motor 6 to rotate back and forth. The waste gas to be treated is introduced into the dispersing cylinder 5 through the inlet pipe 3 and is located below the separator. Therefore, a large amount of gas can only diffuse from both sides to pass through the dispersing holes 501 distributed on the dispersing cylinder 5, and then overflow the surface of the treatment liquid. Through the alternating rotation of the dispersing cylinder 5 and the obstruction of the separator, the continuously introduced waste gas will be guided to both sides and dispersed. Through the multiple sets of distributed dispersing holes 501, the waste gas can effectively disperse and contact the treatment liquid after passing through the dispersing cylinder 5, thereby improving the treatment effect of the waste gas and avoiding a large number of bubbles from accumulating and overflowing directly upward.

[0020] In this invention, a plurality of staggered dispersing members 7 are fixed inside the dispersing cylinder 5. The dispersing members 7 extend radially in the dispersing cylinder 5. The separator is provided with a partition plate 8 fixed to the processing tank 1. The end of the processing tank 1 away from the motor 6 is detachably connected to a mounting plate 10. The end of the partition plate 8 is fixed to the mounting plate 10, and the length of the mounting plate 10 is greater than the length of the separator, so that the separator can be disassembled and installed from the end of the processing tank 1. Horizontal shafts are rotatably connected to both sides of the partition plate 8 by torsion springs. Movable plates 9 are fixed outside the horizontal shafts. The sidewall of the movable plate 9 away from the partition plate 8 slides in contact with the inner wall of the dispersing cylinder 5. Multiple radially extending dispersing elements 7 are arranged inside the dispersing cylinder 5 to facilitate the guidance and dispersion of the incoming waste gas when the dispersing elements 7 rotate to the bottom of the separator, thereby improving the dispersion and treatment effect of the waste gas entering the dispersing cylinder 5. The movable plates 9 on both sides of the partition plate 8 can be deflected up and down to ensure that the dispersing elements 7 rotate past the separator and that the movable plates 9 automatically reset after the dispersing elements 7 have passed. Furthermore, the swing of the movable plates 9 under the action of the torsion spring disperses the bubbles that have gathered on the side of the movable plates 9 away from the partition plate 8, thereby further improving the working effect of the waste gas dispersing and contacting the treatment liquid after entering.

[0021] In this invention, the dispersing component 7 is installed at the distribution position of the dispersing holes 501. The dispersing component 7 is configured as a box structure, and one end of the dispersing component 7 facing the inner wall of the dispersing cylinder 5 is open. The end of the dispersing component 7 away from the inner wall of the dispersing cylinder 5 has multiple perforations 701. Since the movable plates 9 on both sides of the separator can be deflected, some waste gas will flow upward from the side when the movable plates 9 are deflected, and enter the liquid surface and remain in the dispersing cylinder 5. By configuring the dispersing component 7 as a box structure, and allowing liquid to flow only from the dispersing holes 501 and perforations 701 at both ends, when the dispersing component 7 rotates upward and leaves the liquid surface, some treatment liquid will be loaded in the dispersing component 7 and gradually dispersed and flow out from the perforations 701 to further contact and treat the airflow in the dispersing cylinder 5 and above the liquid surface, thereby improving the working effect and treatment efficiency of continuously introduced waste gas treatment.

[0022] Example 2: Refer to Figures 1-8 A non-edible vegetable oil processing waste gas treatment device, based on Example 1, has multiple vertical dispersing components 11 installed on both sides of the treatment tank 1. The multiple vertical dispersing components 11 located on one side of the treatment tank 1 are evenly distributed in the horizontal direction. The vertical dispersing components 11 have a part that moves in the vertical direction as the dispersion cylinder 5 rotates. By moving the vertical dispersing components 11 distributed on both sides of the dispersion cylinder 5 in the vertical direction, the bubbles passing through the dispersion holes 501 from the inside to the outside are further dispersed to ensure the working effect of airflow dispersion and contact reaction with the treatment liquid, thereby improving the completeness and effectiveness of waste gas treatment.

[0023] In this invention, the vertical disassembly component 11 is provided with two vertically extending guide rails 12, which are arranged in parallel. Two disassembly structures are slidably connected between the two guide rails 12, which are located above and below the guide rails 12 respectively. A spring 13 connects the two disassembly structures. Each disassembly structure is provided with two horizontally placed sliding rods 14, which are slidably connected to the two guide rails 12 at both ends. A vertically extending shaft 15 is fixed between the two sliding rods 14. Two blades 16 are rotatably connected to the outer wall of the shaft 15. Each blade 16 has a connecting part facing the shaft 15. The connecting part occupies only half of the blade 16 in the vertical direction, and the connecting plates of the two blades 16 are located above and below the shaft 15 respectively, so that the two disassembly structures can move vertically along the guide rails 12 and the two adjacent blades 16 can rotate and open and close around the shaft 15.

[0024] In this invention, a connecting block 17 is provided between two blades 16. A spring 18 is connected between the side wall of the connecting block 17 and the blade 16. The two ends of the spring 13 are respectively connected to the connecting blocks 17 in the two dispersing structures. A magnetic absorbing plate 19 is fixed on the side of the connecting block 17 facing the dispersing cylinder 5. Multiple grooves 20 are provided on the outer wall of the dispersing cylinder 5. Multiple magnetic blocks 21 installed in the grooves 20 are provided on the outside of the dispersing cylinder 5. In use, the motor 6 drives the dispersing cylinder 5 to rotate back and forth. Under the magnetic attraction between the magnetic blocks 21 on the outer wall of the dispersing cylinder 5 and the magnetic absorbing plates 19 in the vertical dispersing components 11 distributed on both sides of the processing tank 1, the corresponding connecting blocks 17 are pulled up and down by the magnetic attraction force, so that the two adjacent dispersing structures are moved together. It can slide along the guide rail frame 12, and the distance between two adjacent dispersing structures changes back and forth. When the connecting block 17 is pulled under the magnetic attraction, the connecting block 17 moves up and down relative to the blade 16, causing the two adjacent blades 16 to close together. When the magnetic block 21 moves away, the two blades 16 open again. On the one hand, the vertical movement of the vertical dispersing component 11 disperses the bubbles passing through the dispersion cylinder 5. On the other hand, the opening and closing operation between adjacent blades 16 assists in dispersing the bubbles. At the same time, the opening and closing of adjacent blades 16 guides the liquid flow and air flow to disperse to different positions on both sides of the middle position, thereby avoiding the concentration of incoming bubbles and effectively improving the treatment effect of waste gas.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
