Description

Technical Field

[0001] This utility model relates to the field of biochar processing technology, specifically to a biochar processing tail gas treatment mechanism. Background Technology

[0002] The processing of biochar generates a large amount of exhaust gas, which is complex in composition. It contains large impurities, such as incompletely carbonized biochar particles, as well as various harmful substances, including sulfur dioxide, nitrogen oxides, and fine dust. Directly releasing this exhaust gas into the atmosphere would cause serious environmental pollution, harming the ecological balance and human health. Therefore, effective treatment of biochar processing exhaust gas is urgently needed.

[0003] Currently, existing biochar processing tail gas treatment technologies and equipment have significant shortcomings. Most treatment equipment lacks a pretreatment stage for large impurities in the tail gas, allowing these impurities to directly enter subsequent processing steps. This not only easily causes blockages in internal pipes and processing components, reducing equipment lifespan, but also interferes with the treatment effect on harmful substances and dust. Furthermore, the treatment methods are often limited, typically employing only a single filtration or chemical reaction method, making it difficult to achieve efficient and comprehensive purification of multiple pollutants in the tail gas.

[0004] Given that existing biomass charcoal processing tail gas treatment mechanisms suffer from problems such as lack of pretreatment and limited treatment methods affecting treatment effectiveness, it is of great practical significance to develop a tail gas treatment mechanism that can first filter large impurities and then use a reactant to treat harmful substances and dust. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a biochar processing tail gas treatment mechanism that has the advantage of first filtering large impurities and then using a reactant to treat harmful substances and dust. This solves the problem in the prior art where large impurities directly enter the subsequent processing flow, which not only easily causes blockage of the internal pipes and processing components of the equipment, but also results in a single treatment method, usually only using a single filtration or chemical reaction method, making it difficult to achieve efficient and comprehensive purification of multiple pollutants in the tail gas.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biomass charcoal processing tail gas treatment mechanism, comprising a treatment box, an air inlet pipe connected to the left side of the top of the treatment box, a round rod fixedly connected to the center of the upper part of the treatment box, symmetrically arranged permeable filter plates hinged to both sides of the surface of the round rod, the outer ends of the permeable filter plates being inclined downwards, slag discharge troughs opened above both sides of the treatment box, collection boxes connected to the slag discharge troughs fixedly connected to both sides of the treatment box, the outer ends of the permeable filter plates extending into the interior of the collection boxes, and return springs fixedly connected to the front and rear sides of the bottom of the outer ends of the permeable filter plates. The bottom end is fixedly connected to the inner wall of the treatment box via a support plate. A vibration motor is fixedly connected to the center of the top of the treatment box. A vibration plate is fixedly connected to the top of the vibration motor. Vibration rods are fixedly connected to the left and right sides of the bottom of the vibration plate. The bottom ends of the vibration rods penetrate into the interior of the treatment box and fit against the top of the air-permeable filter plate. An isolation plate located below the slag discharge trough is fixedly connected to the interior of the treatment box. An exhaust fan is fixedly connected to the top of the isolation plate. The output end of the exhaust fan penetrates into the bottom of the isolation plate and is connected to an exhaust pipe. An exhaust pipe located below the isolation plate is connected to the right side of the back of the treatment box. A secondary filter cover is threadedly connected to the outer end of the exhaust pipe.

[0007] As a preferred embodiment of this utility model, the bottom of the processing box is fixedly connected to a machine box, and a stirring motor is fixedly connected inside the machine box. The output end of the stirring motor extends through the interior of the processing box and is fixedly connected to a stirring rack.

[0008] In a preferred embodiment of this invention, a sealing sleeve is slidably connected to the surface of the vibrating rod, and the surface of the sealing sleeve is fixedly connected to the inner wall of the processing tank. A sealing bearing is fixedly connected to the surface of the output end of the stirring motor, and the surface of the sealing bearing is fixedly connected to the inner wall of the processing tank.

[0009] As a preferred embodiment of this utility model, the surface of the return spring is fitted with a retractable rubber sleeve, the top of the rubber sleeve is fixedly connected to the bottom of the air-permeable filter plate, and the bottom of the rubber sleeve is fixedly connected to the top of the support plate.

[0010] As a preferred embodiment of this utility model, a first cleaning port is provided on the lower outer side of the collection box, and a detachable first sealing cover is fixedly connected to the surface of the first cleaning port by bolts. A second cleaning port is provided on the lower back of the processing box, and a detachable second sealing cover is fixedly connected to the surface of the second cleaning port by bolts.

[0011] As a preferred embodiment of this utility model, a liquid level observation tank is provided in the center of the lower front of the processing tank, and an explosion-proof transparent glass is fixedly connected inside the liquid level observation tank by sealant.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by placing the air inlet pipe on the top left side of the treatment box, allows exhaust gas to smoothly enter the treatment box. The air-permeable filter plate hinged on the round rod is inclined downward at its outer end. When the exhaust gas enters, large impurities are intercepted by the air-permeable filter plate. Due to its inclined design, the impurities slide down the filter plate to the slag discharge trough and then into the collection box, achieving effective filtration of large impurities in the exhaust gas. The setting of the vibration motor and vibration rod enables the air-permeable filter plate to vibrate, preventing impurities from accumulating on the filter plate and ensuring filtration effect and air permeability. The return spring helps the air-permeable filter plate return to its original position after vibration. The exhaust fan, through the outlet pipe and one-way valve, transports the pre-filtered exhaust gas to the area below the isolation plate to contact the reaction liquid for chemical treatment, preventing backflow of the exhaust gas. The exhaust pipe, secondary filter cover, and internal removable air filter further refine the exhaust gas, removing fine dust and harmful substances, thus improving the quality of exhaust gas treatment. The filling pipe can be used to add reactants to chemically treat harmful substances in the exhaust gas, while the drain valve pipe facilitates the discharge of waste liquid generated during the treatment process. The entire mechanism achieves multi-stage treatment of exhaust gas, effectively improving the exhaust gas treatment effect.

[0013] 2. This utility model provides a stable installation environment for the stirring motor by setting up a casing, and the stirring motor drives the stirring frame to rotate inside the treatment tank. When the reactant is added through the injection pipe, the rotation of the stirring frame ensures that the reactant is fully mixed with harmful substances and dust in the exhaust gas, accelerating the chemical reaction and improving reaction efficiency. This allows the reactant to contact the exhaust gas more evenly, more effectively removing harmful substances and dust from the exhaust gas, further improving the treatment effect and capacity of the entire exhaust gas treatment mechanism.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4 As shown, this utility model provides a biomass charcoal processing tail gas treatment mechanism, including a treatment box 1. An air inlet pipe 2 is connected to the left side of the top of the treatment box 1. A round rod 3 is fixedly connected to the center of the upper part of the treatment box 1. Symmetrically arranged permeable filter plates 4 are hinged to both sides of the surface of the round rod 3. The outer ends of the permeable filter plates 4 are inclined downwards. Slag discharge troughs are opened on the upper parts of both sides of the treatment box 1. Collection boxes 5, connected to the slag discharge troughs, are fixedly connected to both sides of the treatment box 1. The outer ends of the permeable filter plates 4 extend into the interior of the collection boxes 5. Return springs 6 are fixedly connected to the front and rear sides of the bottom of the outer ends of the permeable filter plates 4. The bottom ends of the return springs 6 are fixedly connected to the inner wall of the treatment box 1 via support plates. A vibration motor 7 is fixedly connected to the center of the top of the treatment box 1. A vibration motor is fixedly connected to the top of the vibration motor 7. Vibrating rods 9 are fixedly connected to the left and right sides of the bottom of the plate 8 and the bottom end of the vibrating rods 9 penetrates into the interior of the treatment box 1 and fits against the top of the air-permeable filter plate 4. An isolation plate 10 located below the slag discharge trough is fixedly connected inside the treatment box 1. An exhaust fan 11 is fixedly connected to the top of the isolation plate 10. The output end of the exhaust fan 11 penetrates into the bottom of the isolation plate 10 and is connected to an exhaust pipe 12 through a one-way valve. An exhaust pipe 13 located below the isolation plate 10 is connected to the right side of the back of the treatment box 1. A secondary filter cover 14 is threaded to the outer end of the exhaust pipe 13. A removable air filter element is installed inside the secondary filter cover 14. A filling pipe is connected to the left side of the front of the treatment box 1. A sealing pipe cap is threaded to the top of the filling pipe. A drain valve pipe (not shown) is connected to the lower right side of the treatment box 1.

[0018] refer to Figure 3 The bottom of the processing box 1 is fixedly connected to the housing 15. The housing 15 is fixedly connected to the stirring motor 16. The output end of the stirring motor 16 passes through the inside of the processing box 1 and is fixedly connected to the stirring rack 17.

[0019] As a technical optimization of this utility model, the housing 15 provides a stable installation environment for the stirring motor 16, which drives the stirring frame 17 to rotate within the treatment tank 1. When reactant is added through the injection pipe, the rotation of the stirring frame 17 ensures thorough mixing of the reactant with harmful substances and dust in the exhaust gas, accelerating the chemical reaction and improving reaction efficiency. This allows the reactant to contact the exhaust gas more evenly, more effectively removing harmful substances and dust, further enhancing the overall treatment effect and capacity of the exhaust gas treatment system.

[0020] refer to Figure 3 A sealing sleeve 18 is slidably connected to the surface of the vibrating rod 9, and the surface of the sealing sleeve 18 is fixedly connected to the inner wall of the processing box 1. A sealing bearing 19 is fixedly connected to the surface of the output end of the stirring motor 16, and the surface of the sealing bearing 19 is fixedly connected to the inner wall of the processing box 1.

[0021] As a technical optimization of this utility model, the sealing sleeve 18 is slidably connected to the surface of the vibrating rod 9 and fixed to the inner wall of the processing box 1. It can prevent the exhaust gas in the processing box 1 from leaking through the penetration of the vibrating rod 9, ensuring the sealing of the processing box 1 and avoiding pollution to the environment caused by exhaust gas leakage. The sealing bearing 19 is fixed to the surface of the output end of the stirring motor 16 and fixed to the inner wall of the processing box 1, which also plays a sealing role, preventing the reaction liquid in the processing box 1 from leaking through the gap of the output end of the stirring motor 16, improving the reliability and stability of the equipment, and extending the service life of the equipment.

[0022] refer to Figure 3 A retractable rubber sleeve 20 is fitted on the surface of the return spring 6. The top of the rubber sleeve 20 is fixedly connected to the bottom of the air-permeable filter plate 4, and the bottom of the rubber sleeve 20 is fixedly connected to the top of the support plate.

[0023] As a technical optimization of this utility model, by setting a rubber sleeve 20, the top of which is fixed to the bottom of the air-permeable filter plate 4 and the bottom of which is fixed to the top of the support plate, it can prevent impurities, dust and other substances in the treatment box 1 from adhering to the return spring 6, and prevent the return spring 6 from losing its elasticity due to corrosion or being stuck by impurities. The stretchable characteristic of the rubber sleeve 20 ensures that the normal stretching function of the return spring 6 will not affect the normal stretching function of the air-permeable filter plate 4 during vibration and return to its original position, thus extending the service life of the return spring 6 and improving the stability and reliability of the entire air-permeable filter plate 4 assembly.

[0024] refer to Figure 2A first cleaning port is provided on the lower outer side of the collection box 5, and a detachable first sealing cover plate 21 is fixedly connected to the surface of the first cleaning port by bolts. A second cleaning port is provided on the lower back of the processing box 1, and a detachable second sealing cover plate 22 is fixedly connected to the surface of the second cleaning port by bolts.

[0025] As a technical optimization of this utility model, by setting the first cleaning port and the first sealing cover 21 on the lower outer side of the collection box 5, it is convenient to regularly clean large impurities collected in the collection box 5. By removing the first sealing cover 21, the collected impurities can be easily removed, preventing excessive accumulation of impurities in the collection box 5 and affecting the slag discharge effect of the air-permeable filter plate 4. The second cleaning port and the second sealing cover 22 are located on the lower back of the treatment box 1, which facilitates the cleaning of sediment and impurities accumulated at the bottom of the treatment box 1. Regularly cleaning these impurities can ensure the cleanliness of the treatment box 1, prevent impurities from causing wear and corrosion to the internal components of the equipment, and improve the operating efficiency and service life of the equipment.

[0026] refer to Figure 1 A liquid level observation tank 23 is provided in the center of the lower front of the processing tank 1. An explosion-proof transparent glass is fixedly connected inside the liquid level observation tank 23 by sealant.

[0027] As a technical optimization of this utility model, the inclusion of a liquid level observation tank 23 and explosion-proof transparent glass allows operators to directly observe the liquid levels of the reactant and waste liquid within the treatment tank 1. When adding reactant, the amount added can be accurately controlled based on the liquid level, preventing excessive or insufficient addition from affecting the treatment effect. Simultaneously, when the waste liquid reaches a certain level, operators can promptly drain it through the drain valve, preventing overflow and adverse effects on the equipment and environment.

[0028] The working principle and usage process of this utility model are as follows: During use, the exhaust outlet is connected to the inlet pipe 2 via a flange. An appropriate amount of reaction liquid is injected into the treatment tank 1 through the injection pipe, ensuring it covers the bottom of the outlet pipe 12. When the tail gas generated from biomass charcoal processing enters the treatment tank 1 through the inlet pipe 2, it first encounters the permeable filter plate 4. Because the permeable filter plate 4 is inclined downwards at its outer end, large impurities in the tail gas are intercepted and slide down the filter plate into the slag discharge trough, eventually falling into the collection box 5. Simultaneously, the vibration motor 7 drives the vibration plate 8 and vibration rod 9 to vibrate, causing the permeable filter plate 4 to vibrate as well, preventing impurities from accumulating on the filter plate and ensuring its permeability. The filtration effect is enhanced by the return spring 6, which helps the breathable filter plate 4 return to its original position after vibration. The exhaust gas, after initial filtration, is transported by the exhaust fan 11 through the outlet pipe 12 and one-way valve to the area below the isolation plate 10 to react with the reaction liquid. At this time, the stirring motor 16 drives the stirring frame 17 to rotate, ensuring the reactant mixes thoroughly with harmful substances and dust in the exhaust gas, undergoing a chemical reaction to further remove pollutants. The treated exhaust gas is discharged through the exhaust pipe 13. During discharge, the air filter element in the secondary filter hood 14 performs a final fine filtration, removing fine dust and residual harmful substances. During the process, operators can observe the levels of reactant and waste liquid in the treatment tank 1 through the liquid level observation tank 23. When the waste liquid reaches a certain level, it can be discharged through the drain valve. Furthermore, periodically opening the first sealing cover 21 of the first cleaning port and the second sealing cover 22 of the second cleaning port allows for the removal of large impurities in the collection tank 5 and sediment at the bottom of the treatment tank 1, ensuring normal operation and treatment effectiveness.
