Description

Technical Field

[0001] The present invention relates to the technical field of biological fermentation malodorous gas treatment, and specifically, it is a plasma treatment device for biological fermentation malodorous gas. Background Art

[0002] Biological fermentation is a process in which microorganisms (such as bacteria, yeasts, fungi, etc.) convert organic substances (such as sugars, starches, fats, etc.) into other chemical substances (such as alcohols, acids, gases, etc.) under suitable environments. This process is widely used in multiple fields such as food, medicine, energy, and environmental protection. When conducting biological fermentation, tools such as fermentation tanks are usually required, and malodorous gases will be generated during the fermentation process. These malodorous gases have a pungent smell. If directly discharged into the external environment, it will cause environmental pollution. Therefore, it is necessary to treat them.

[0003] In the prior art, when treating malodorous gases, plasma is usually used for treatment. The specific operation is to connect a plasma generator into a pipeline containing malodorous gases, and use the plasma generated by the plasma generator to deodorize the malodorous gases in the pipeline. However, in this treatment method, when the plasma generator is directly put into the pipeline for deodorization, although ozone can be generated and combined with the plasma to jointly deodorize the odor, due to the relatively fast plasma reaction and the large amount of ozone generated, after the reaction, there are still a large amount of ozone and other oxidation substances in the gas, which are discharged together with the treated gas, causing environmental pollution problems.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The plasma generator generates plasma and ozone in the plasma box. The ozone concentration in the plasma box is detected by an ozone sensor. When the set concentration is reached, the plasma generator is turned off and the gas mixing drive motor is started. The drive gear rotates driven by the output end of the gas mixing drive motor, the drive gear drives the transmission gear to rotate, the transmission gear drives the drive disc to rotate, the drive disc drives the drive rod to rotate, and the drive rod drives the reciprocating ring to move horizontally along the surfaces of the two limit rods.

The drive rod rotates driven by the drive disc, the drive rod drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the intake fan to rotate, causing the gas in the ozone delivery tube to flow. The odor gas is inhaled through the intake pipe, and after the particulate matter is filtered by the second filter plate in the filter box, the electronic valve is opened to deliver the odor gas into the odor gas shunt tube, for proportioning and deodorizing the ozone, plasma and odor gas, preventing excessive ozone from being discharged into the environment and causing environmental pollution.

[0016] 2. The plasma and ozone are delivered to the mixing shell through the plasma guiding tube, and the odor gas is delivered to the mixing shell through multiple odor guiding tubes on the odor gas shunt tube, enabling the odor gas, plasma and ozone to be fully mixed. The S-shaped deodorizing tube delays the outflow of the gas, enabling it to be fully mixed and deodorized, extending the reaction time and enhancing the deodorizing effect.

[0017] 3. The gas after deodorization enters the integrated tube to gather and then enters the activated carbon box. At this time, it is discharged into the activated carbon box through the discharge port on one side of the activated carbon box. The sulfide in the odor gas is secondarily adsorbed and purified by an activated carbon filter plate in the activated carbon box, further improving the purification effect.

Detailed implementation manners

[0020] The following further describes the present invention with specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the drawings is for better explanation. The structure of the present invention necessarily goes beyond these limited embodiments, and for some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of the present application.

[0021] Figures 1 to 9 It is the best embodiment of the present invention. The following further describes the present invention with reference to the attached Figures 1 to 9 drawings.

[0022] As Figures 1 to 9 shown, a biological fermentation malodorous gas plasma treatment device includes a box body 1. An air inlet is provided on one side of the box body 1, and an air outlet is provided on the other side of the box body 1. A deodorizing and mixing assembly is fixedly installed on the inner wall of the box body 1; The deodorizing mixing assembly includes an odor diversion pipe 42 and a plasma diversion pipe 48. The odor diversion pipe 42 is fixedly installed on the inner wall of the box body 1. Odor guiding pipes 44 are fixedly installed in multiple diversion holes of the odor diversion pipe 42. The other ends of the odor guiding pipes 44 are fixedly installed with mixing shells 45. The plasma diversion pipe 48 is fixedly installed on the inner wall of the box body 1. Plasma guiding pipes 47 are fixedly installed in multiple diversion holes of the plasma diversion pipe 48. The other ends of the plasma guiding pipes 47 are fixedly connected to the upper side of the mixing shell 45. Deodorizing pipes 10 are fixedly installed on one side of multiple mixing shells 45. One ends of multiple deodorizing pipes 10 are fixedly installed with a tail gas treatment assembly. The deodorizing pipes 10 are in an S-shaped bend. An odor addition assembly is fixedly installed on one side of the odor diversion pipe 42. A plasma addition assembly is fixedly installed on one side of the plasma diversion pipe 48.

[0023] With the above structure, the odor diversion pipe 42 inside the box body 1 is located below the plasma diversion pipe 48, and the number of diversion holes on one side of the two is the same. The plasma guiding pipes 47 and the odor guiding pipes 44 installed on the diversion holes are symmetrically installed, and their one ends are commonly connected to the same mixing shell 45. A deodorizing pipe 10 in an S shape is correspondingly installed on one side of the mixing shell 45. The deodorizing pipe 10 is set in an S shape, which can reduce the occupied area and extend the reaction time of the odor, plasma, and ozone, enhancing the deodorizing effect. The number of deodorizing pipes 10 is the same as the number of mixing shells 45. The other ends of the deodorizing pipes 10 are connected to the tail gas treatment assembly for adsorbing and treating sulfides in the malodorous gas. By transporting a certain amount of ozone and plasma through the plasma diversion pipe 48 via the plasma guiding pipes 47, and then introducing the corresponding amount of malodorous gas through the odor diversion pipe 42 via the odor guiding pipes 44 into the same mixing shell 45 and carrying out sufficient reaction and deodorization through the deodorizing pipes 10, it avoids directly placing the plasma generator 12 into the pipeline to directly react with the malodorous gas, effectively controlling the dosage of ozone and preventing excess unreacted ozone from being discharged to the outside and polluting the environment.

[0024] Furthermore, the odor addition assembly includes an electronic valve 24. The discharge end of the electronic valve 24 is fixedly installed on one side of the odor diversion pipe 42. The inlet end of the electronic valve 24 is fixedly installed with an odor delivery pipe 41. The other end of the odor delivery pipe 41 is fixedly installed with a filter box 14. A filter net 15 is arranged inside the filter box 14. The other side of the filter box 14 is fixedly installed with an intake pipe 9. The intake pipe 9 is fixedly installed on one side of the box body 1 and extends outside the box body 1.

[0025] With the above structure, the electronic valve 24 can be controlled by the controller 3. The odor delivery pipe 41 and the odor diversion pipe 42 are connected through the electronic valve 24. Using the electronic valve 24 here can control the discharge of the malodorous gas and prevent gas leakage when it is not being treated. The filter box 14 connected to the odor delivery pipe 41 has a filter net 15 inside it, which can filter the particulate matter in the malodorous gas, prevent it from affecting the subsequent treatment, and can also provide a certain degree of protection for the first-stage bevel gear 21 and the second-stage bevel gear 22. One side of the filter box 14 is installed with a cover plate through a plurality of bolts, which facilitates the replacement of the filter net 15.

[0026] Furthermore, the plasma addition component includes a vacuum tube 25. The vacuum tube 25 is fixedly installed on one side of the plasma diversion pipe 48. A piston 26 is slidably installed on the inner wall of the vacuum tube 25. The surface of the vacuum tube 25 is fixedly installed with a plasma delivery pipe 18 and extends into the interior of the vacuum tube 25. A plasma box 7 is fixedly installed on the upper side of the box body 1. A plasma generator 12 is fixedly installed on the inner bottom wall of the plasma box 7. The plasma delivery pipe 18 is fixedly installed on the plasma box 7 and extends into the interior of the plasma box 7. A ventilation opening is provided on one side of the plasma box 7, and a one-way pipe 8 is fixedly installed in the ventilation opening. An air injection unit is fixedly installed on the inner wall of the box body 1.

[0027] With the above structure, the piston 26 fits against the inner wall of the vacuum tube 25. The vacuum tube 25 is connected to the plasma box 7 through the plasma delivery pipe 18. The plasma generator 12 in the plasma box 7 can generate plasma in the plasma box 7 and generate ozone. The one-way pipe 8 installed on one side of the plasma box 7 has a conveying direction from the outside to the inside of the plasma box 7. When plasma and ozone need to be transported, the plasma is transported into the interior of the vacuum tube 25 through the plasma delivery pipe 18 and is pushed into the plasma diversion pipe 48 by the piston 26 to complete the injection.

[0028] Furthermore, the air injection unit includes two limiting rods 30. The same reciprocating ring 28 is slidably installed on the surfaces of the two limiting rods 30. A driving port is provided on the surface of the reciprocating ring 28, and a driving rod 55 is slidably installed in the driving port. A reciprocating block 29 is fixedly installed on the upper side of the reciprocating ring 28. An L-shaped rod 27 is fixedly installed on the upper side of the reciprocating block 29. The other end of the L-shaped rod 27 is fixedly installed on one side of the piston 26. A first-stage one-way valve 17 is provided on the plasma delivery pipe 18. A driving rod 20 is rotatably installed on the odor delivery pipe 41 and extends into the odor delivery pipe 41. A driving disk 52 is fixedly installed at the top of the driving rod 20. The lower side of the driving rod 55 is rotatably installed on the upper side of the driving disk 52.

[0029] With the above structure, the two limiting rods 30 are respectively installed on both sides of the reciprocating ring 28. Sleeve rings are fixedly installed on both sides of the reciprocating ring 28, and are slidably connected to the surfaces of the two limiting rods 30 through the sleeve rings. The driving rod 55 is installed in the outer ring area of the driving disk 52, and the circular movement diameter thereof is equal to the length of the driving port, preventing the driving rod 55 from being limited in movement. The direction of the first one-way valve 17 on the plasma delivery pipe 18 is from the plasma box 7 to the vacuum pipe 25. When the reciprocating ring 28 moves horizontally on the limiting rods 30, the L-shaped rod 27 is driven by the reciprocating block 29 to perform horizontal reciprocating movement, and under the action of the first one-way valve 17, the piston 26 is driven to extract and push the plasma and ozone.

[0030] Further, the gas injection unit further includes an intake fan 23. An installation ring 53 is fixedly installed on the inner wall of the odor delivery pipe 41. The intake fan 23 is rotatably installed on the installation ring 53. A first bevel gear 21 is fixedly installed on the surface of the driving rod 20, and a second bevel gear 22 is fixedly installed at the handle end of the intake fan 23. The first bevel gear 21 meshes with the second bevel gear 22.

[0031] With the above structure, the intake fan 23 is composed of a fan handle and fan blades. It is rotatably connected to the fan handle through the installation ring 53 fixed in the delivery pipe. The surfaces of the second bevel gear 22 installed at the fan handle end and the first bevel gear 21 installed on the surface of the driving rod 20 are both treated with anti-corrosion to meet the normal use in the malodorous gas environment. When the driving rod 20 rotates, the second bevel gear 22 is driven by the first bevel gear 21 to rotate, and the intake fan 23 is rotated to inhale the malodorous gas.

[0032] Further, a gas mixing driving motor 19 is fixedly installed on the upper side of the filter box 14. The output end of the gas mixing driving motor 19 is fixedly installed with a driving gear 31. A transmission gear 32 is fixedly installed on the surface of the driving rod 20. The driving gear 31 meshes with the transmission gear 32. An ozone sensor 13 is fixedly installed on the inner wall of the plasma box 7. The ozone sensor 13 is electrically connected to the gas mixing driving motor 19.

[0033] With the above structure, the ozone sensor 13 is a prior art, which can detect the ozone concentration in the plasma box 7, and is electrically connected to the controller 3. The threshold value is set through the controller 3 for calibrating and processing the proportional malodorous gas. When the concentration monitored by the ozone sensor 13 reaches the corresponding threshold value, the plasma generator 12 is first turned off, and at the same time, the gas mixing driving motor 19 is turned on, and power is provided to the relevant structure through the driving gear 31 and the transmission gear 32, so as to convey the generated ozone and plasma and mix them with the proportional malodorous gas. In order to ensure the treatment ratio of the malodorous gas, the intake amount of the malodorous gas can be adjusted by adjusting the intake size of the intake fan 23 or the transmission ratio of the driving gear 31 and the transmission gear 32, so as to achieve the established treatment ratio.

[0034] Furthermore, the tail gas treatment assembly includes an activated carbon box 16 which is fixedly installed on the inner wall of the box body 1. The other ends of a plurality of deodorizing pipes 10 are fixedly installed with the same integrated pipe 54. The other side of the integrated pipe 54 is fixedly connected to the activated carbon box. A discharge port 46 is formed on one side of the activated carbon box, and one side of the activated carbon box is communicated with the discharge port 46. A plurality of activated carbon filter plates are arranged on the inner wall of the activated carbon box, and the activated carbon plates correspond to the discharge port 46. An installation port is formed on the upper side of the box body 1, and the upper side of the activated carbon box is communicated with the installation port. An installation cover 6 is installed on the installation port through bolts. Two extrusion springs 35 are fixedly installed on the lower side of the installation cover 6, and the same lower pressing plate 36 is fixedly installed at the bottom ends of the two extrusion springs 35. An ejection port 4 is formed on one side of the box body 1, and the ejection port 4 is communicated with the activated carbon box. A sliding port is formed on the lower side of the activated carbon box, and a replacement unit is fixedly installed in the sliding port.

[0035] With the above structure, the activated carbon box is L-shaped, with openings provided at its top, one end and one side. The opening at the top is communicated with the installation port to facilitate the addition of unused activated carbon filter plates. The opening at one end is communicated with the ejection port 4 to facilitate the discharge of the used activated carbon filter plates. The opening at one side is communicated with the exhaust port to facilitate the transportation of the reacted gas. Five activated carbon filter plates can be loaded inside it, four of which are filter plates to be replaced and one is the activated carbon filter plate in use. The installation cover 6 installed in the installation port uses two extrusion springs 35 to push the lower pressing plate 36 to assist in loading the activated carbon filter plates. The maximum extension depth of the extrusion springs 35 is at the turning point of the L-shape and does not touch the inner bottom wall of the activated carbon box. The integrated pipe 54 communicated with one side of the activated carbon box is used to concentrate the reacted gas and make it enter the activated carbon box for secondary filtration treatment.

[0036] Furthermore, the replacement unit includes a driving block 38 which is slidably installed in the sliding port. An extrusion block 40 is fixedly installed on the upper side of the driving block 38. An extension plate 34 is fixedly installed on one side of the extrusion block 40. A limiting port is formed on one side of the activated carbon box, and the extension plate 34 fits in the limiting port. One side of the extrusion block 40 is in contact with one side of the activated carbon filter plate. A replacement motor 39 is fixedly installed on the inner wall of the box body 1. A reciprocating lead screw 37 is fixedly installed at the output end of the replacement motor 39. The driving block 38 is screwed on the surface of the reciprocating lead screw 37. An exhaust pipe 5 is fixedly installed in the exhaust port. A rain-proof cover 11 is fixedly installed at the top end of the exhaust pipe 5. A sulfide sensor 51 is fixedly installed on the inner wall of the exhaust pipe 5, and the sulfide sensor 51 is electrically connected to the replacement motor 39.

[0037] With the above structure, the exhaust pipe 5 is L-shaped. The rain cover 11 installed at its top prevents external water from entering the exhaust pipe 5. The sulfide sensor 51 installed inside it is a prior art, which is convenient for detecting sulfide in the gas. When sulfide is detected, the replacement motor 39 will be controlled to start. In order to prevent the replacement motor 39 from repeatedly starting after all the activated carbon filter plates are used up, the controller 3 can be used to set the start times of the replacement motor 39 according to the number of activated carbon filter plates to be replaced. Each time it starts, an activated carbon filter plate will be replaced. When the start times are exhausted, it means that the activated carbon filter plates are used up. At this time, the replacement motor 39 will no longer start and an alarm will be given to prompt to replenish the activated carbon plates. The extension plate 34 installed on one side of the extrusion block 40 fits and limits the activated carbon filter plate, preventing the extrusion block 40 from causing the activated carbon filter plate to be replaced to be misaligned and skewed due to insufficient contact area during extrusion replacement. When the replacement motor 39 starts, the output end drives the reciprocating screw rod 37 to rotate. The reciprocating screw rod 37 drives the driving block 38 to move along the sliding port. The driving block 38 drives the extrusion block 40 to move. The extrusion block 40 extrudes the activated carbon filter plate to be replaced. The activated carbon filter plate to be replaced extrudes the activated carbon filter plate to be replaced and extrudes it into the ejection port 4 along the activated carbon box 16 for discharge. When the extrusion block 40 reaches the maximum moving position, the ventilation plate 50 on the activated carbon filter plate to be replaced fits in the discharge port 46 for filtration and adsorption. At this time, the extrusion block 40 resets. When it is completely reset, the replacement motor 39 stops running. At this time, the remaining activated carbon filter plates are extruded downward by the two extrusion springs 35 and the lower pressing plate 36, so that they enter the inner bottom wall of the activated carbon box 16, thus completing the replacement, avoiding frequent manual disassembly for replacement and saving human resources.

[0038] Further, the activated carbon filter plate includes a housing 33. The housing 33 fits against the inner wall of the activated carbon box. Activated carbon is provided inside the housing 33. Two ventilation plates 50 are fixedly installed on the inner wall of the housing 33.

[0039] With the above structure, both sides of the housing 33 are penetrated, and the size is the same as that of the discharge port 46 and the exhaust port. When the housing 33 is pushed to the use position, the three are communicated. The housing 33 cooperates with the two ventilation plates 50 to fill the activated carbon and can adsorb sulfide in the gas to purify the gas.

[0040] Further, a box door 2 is rotatably installed on one side of the box body 1. A controller 3 is fixedly installed on one side of the box body 1. A secondary one-way valve 43 is provided on the odor guiding pipe 44, and a tertiary one-way valve 49 is provided on the plasma guiding pipe 47.

[0041] With the above structure, the cabinet door 2 can be used for inspection and maintenance of the device. Through the controller 3, the electronic components in the device can be controlled. The direction of the secondary one-way valve 43 on the odor guiding pipe 44 is from the odor shunt pipe 42 to the inside of the mixing housing 45, and the direction of the tertiary one-way valve 49 on the plasma guiding pipe 47 is from the plasma shunt pipe 48 to the inside of the mixing housing 45, which can effectively prevent the reverse flow of gas and the problem of affecting mixing.

[0042] Working principle: When the device is in use, first install one end of the intake pipe 9 at the biological fermentation tank or the exhaust port so that the odor generated by fermentation can smoothly enter the intake pipe 9 to complete the installation of the device.

[0043] When odor treatment is required, first start the plasma generator 12 through the controller 3. The plasma generator 12 generates plasma and ozone in the plasma chamber 7. The ozone concentration in the plasma chamber 7 is detected by the ozone sensor 13. When the established concentration is reached, turn off the plasma generator 12 and start the gas mixing drive motor 19 to start the treatment of malodorous gases.

[0044] The output end of the gas mixing drive motor 19 drives the drive gear 31 to rotate. The drive gear 31 drives the transmission gear 32 to rotate. The transmission gear 32 drives the drive disk 52 to rotate. The drive disk 52 drives the drive rod 55 to rotate. The drive rod 55 drives the reciprocating ring 28 to move horizontally along the surfaces of the two limit rods 30. The reciprocating ring 28 drives the L-shaped rod 27 to move through the reciprocating block 29. The L-shaped rod 27 drives the piston 26 to reciprocate. When the piston 26 is pulled out of the vacuum tube 25, the plasma and ozone in the plasma chamber 7 are inhaled through the plasma delivery pipe 18. When the piston 26 is pushed into the vacuum tube 25, under the action of the primary one-way valve 17, ozone enters the plasma shunt pipe 48 and enters the mixing pipe through multiple plasma guiding pipes 47. At this time, the drive disk 52 drives the drive rod 20 to rotate. The drive rod 20 drives the primary bevel gear 21 to rotate. The primary bevel gear 21 drives the secondary bevel gear 22 to rotate. The secondary bevel gear 22 drives the intake fan 23 to rotate, causing the gas in the ozone delivery pipe to flow, and inhaling the odor through the intake pipe 9. After filtering the particulate matter through the secondary filter plate in the filter box 14, the electronic valve 24 is opened to deliver the odor to the odor shunt pipe 42, and then it is delivered to the mixing housing 45 through multiple odor guiding pipes 44 on the odor shunt pipe 42. The plasma, ozone and odor are fully mixed and enter the deodorizing pipe 10. The S-shaped deodorizing pipe 10 delays the outflow of the gas to make it fully mixed and deodorized.

[0045] The gas after deodorization enters the integrated pipe 54 to gather and then enters the activated carbon box 16. At this time, it is discharged into the activated carbon box 16 through the discharge port 46 on one side of the activated carbon box 16. The sulfide in the odor is secondarily adsorbed and purified by an activated carbon filter plate in the activated carbon box 16, and finally discharged through the exhaust pipe 5.

[0046] As ozone is gradually added, the ozone concentration in the plasma box 7 gradually decreases. When the ozone concentration returns to zero, it means that all the ozone generated in a single time has been completely consumed. At this time, the mixed gas drive motor 19 will stop, thus ending the purification of the malodorous gas this time, avoiding excessive ozone that cannot participate in the reaction from being discharged into the environment together with the gas, causing environmental pollution.

[0047] When the activated carbon filter plate is in use, if the adsorption capacity reaches the upper limit, it will be unable to filter sulfide. At this time, the sulfide sensor 51 in the exhaust pipe 5 will detect the discharge of sulfide and start the replacement motor 39. The output end of the replacement motor 39 drives the reciprocating lead screw 37 to rotate. The reciprocating lead screw 37 drives the driving block 38 to move along the sliding port. The driving block 38 drives the extrusion block 40 to move. The extrusion block 40 extrudes the activated carbon filter plate to be replaced. The activated carbon filter plate to be replaced extrudes the activated carbon filter plate to be replaced and extrudes it along the activated carbon box 16 to the ejection port 4 for discharge. When the extrusion block 40 reaches the maximum moving position, the ventilation plate 50 on the activated carbon filter plate to be replaced fits in the discharge port 46 for filtration and adsorption. At this time, the extrusion block 40 resets. After complete reset, the replacement motor 39 stops running. At this time, the remaining activated carbon filter plates are extruded downward by two extrusion springs 35 and the lower pressing plate 36, so that they enter the inner bottom wall of the activated carbon box 16, thus completing the replacement.
