Description

Technical Field

[0001] This invention relates to the field of environmental protection technology, specifically to a laboratory wastewater and waste gas treatment device. Background Technology

[0002] In the laboratory, researchers often need to mix, react, and separate different chemical substances to conduct various experiments. These experiments typically require large amounts of water to wash glassware, collect reaction products, or perform other experimental steps. However, because the organic samples involved in the experiments may have a certain degree of toxicity or hazard, the wastewater or exhaust gases generated during the experiments often need to be properly treated to ensure the safety of the environment and personnel.

[0003] To effectively treat laboratory wastewater, existing wastewater treatment systems typically employ chemical and physical methods. However, these methods have drawbacks, such as high treatment costs and significant environmental impact. To address these issues, laboratories have increasingly adopted biological treatment systems in recent years. These systems utilize the activity of microorganisms to degrade organic matter, transforming it into more stable and environmentally friendly substances.

[0004] Currently, biological treatment methods are widely used in laboratory wastewater treatment systems. This method introduces microorganisms, such as bacteria, fungi, and algae, and utilizes their metabolic activity to degrade organic waste into safer compounds. The treatment process typically involves collecting wastewater through pipelines for centralized treatment. Maintaining a certain level of microbial activity during treatment is crucial to ensure the effective degradation of organic matter in the wastewater.

[0005] However, a problem with existing technologies is that when treating high volumes of wastewater, the burden on microorganisms may become excessive, leading to a decrease in degradation efficiency. Fluctuations in wastewater volume may also prevent microorganisms from fully adapting, thus affecting the stability of the treatment system. Furthermore, the nutrient supply to microorganisms is a key factor affecting the effectiveness of biological treatment, and during the treatment process, biological packing materials need to be added periodically to ensure a sufficient nutrient supply for the microorganisms. Summary of the Invention

[0006] To address the aforementioned problems, the present invention aims to provide a laboratory wastewater and waste gas treatment device.

[0007] To achieve this technical objective, the present invention provides a laboratory wastewater and waste gas treatment device, comprising a housing.

A V-shaped water guide plate is installed on the drainage tank, with a drain pipe connected to the bottom of the V-shaped water guide plate. The other end of the drain pipe is connected to the support plate, allowing wastewater to enter the wastewater treatment tank through the V-shaped water guide plate and the drain pipe. The height of the housing is higher than the height of the operating platform. A wastewater pouring port and a waste gas intake port are located on the side of the housing near the operating platform.

[0013] The feed tube is equipped with a spring sheet inside, and the spring sheet extends through the upper wall of the feed tube to the side of the baffle. The side of the baffle is provided with protrusions at intervals. When the protrusions move, they contact the spring sheet to drive the spring sheet to vibrate.

[0014] Preferably, the wastewater treatment tank is provided with an exhaust pipe through the support plate to prevent excessive air pressure inside the wastewater treatment tank. The other end of the exhaust pipe extends through the shell to the fixed plate, and the other outlet end of the exhaust pipe is provided on the exhaust gas treatment component. The exhaust gas discharged from the wastewater treatment tank is further treated by the exhaust gas treatment component.

[0015] Preferably, a push-button valve is installed on the side of the exhaust pipe near the support rod;

[0016] The push valve includes a valve body installed on the exhaust pipe and a valve seat disposed inside the valve body. A valve core is also disposed inside the valve body. A valve stem is connected to one side of the valve core, and a pressure block is connected to the other end of the valve stem. A first oblique surface is disposed on one side of the pressure block. A return spring is sleeved on the valve stem. One end of the return spring abuts against the pressure block, and the other end of the return spring abuts against the valve body, so that the valve core can be easily reset.

[0017] A pressing block is also fixedly connected to the side of the support rod. The pressing block is provided with a second oblique surface that matches the first oblique surface. When the pressing block moves upward, it is used to drive the movement of the pressing block, thereby controlling the opening and closing of the pressing valve.

[0018] Preferably, a cleaning mechanism is provided inside the housing between the fixed plate and the V-shaped water guide plate;

[0019] The cleaning mechanism includes a rectangular frame disposed inside the housing, a ring of cleaning brushes disposed on the side of the rectangular frame near the housing, two sets of sliding grooves being provided on the inner wall of the housing, and sliding strips being slidably connected in the two sets of sliding grooves, the sides of the sliding strips being fixedly connected to the rectangular frame, and a rack being provided on the sliding strips, and a drive mechanism being installed on the exhaust pipe.

[0023] The beneficial effects of this invention are:

[0024] 1. The introduction of the telescopic mechanism in this case makes the wastewater treatment device more adaptable. When treating high wastewater volumes, the device can promptly increase the frequency of adding biological packing material to ensure sufficient nutrient supply and activity for microorganisms; it can also adjust the amount of biological packing material added in real time to ensure that the nutrient supply to microorganisms matches the characteristics of the current wastewater, thereby maximizing microbial activity and improving wastewater degradation efficiency. Adjusting the addition of biological packing material according to changes in wastewater volume allows for more effective resource utilization, reduces waste, and improves the energy efficiency of the treatment system.

[0025] 2. In this case, the waste gas treatment component draws in waste gas through the intake port, filters it through multiple filter plates to meet emission standards, and then discharges it through the exhaust pipe. This prevents the generation of toxic gases during the experiment from causing poisoning by inhaling them, while also ensuring that the discharged waste gas meets environmental standards. The device is designed as a comprehensive treatment system capable of simultaneously treating wastewater and waste gas, ensuring that different forms of waste generated in the laboratory are effectively treated.

[0038] The following is in conjunction with the appendix Figure 1-11 The invention described in this application will be further described in detail with specific embodiments. To provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content described in this application without inventive effort are all within the scope of protection of this invention.

[0039] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of clearly describing this embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Example 1

[0041] In laboratories, researchers frequently conduct various experiments involving the mixing, reaction, and separation of different chemical substances. These experiments typically require the use of large amounts of water to wash glassware, collect reaction products, or perform other experimental steps. However, because the chemical substances involved in these experiments may possess a degree of toxicity or hazard, the wastewater or exhaust gases generated during the experiments often need to be properly treated to ensure the safety of the environment and personnel.

[0042] To treat this wastewater, the laboratory employs a specialized wastewater treatment system. Wastewater is collected through pipelines and treated centrally. During the treatment process, the laboratory often uses biological treatment methods, utilizing the activity of microorganisms (such as bacteria, fungi, and algae) to degrade organic matter, transforming it into more stable and environmentally friendly substances. The treated water meets certain standards and can be safely discharged into the city's sewage system or used for other suitable purposes.

[0043] To address the aforementioned problems, this application discloses a laboratory wastewater and waste gas treatment device. Please refer to [link / reference needed]. Figures 1-6 The system includes a housing 1, with an internal partition 2 dividing the housing 1 into an operating platform 3 and a processing mechanism 4. The operating platform 3 has a storage box 31 for storing biological fillers, with a storage cavity 33 below the storage box 31. The operating platform 3 has a door panel 32 on its front. The processing mechanism 4 includes a housing 41, with an internal support plate 42 dividing the housing 41 into a wastewater treatment tank 43 and a drainage tank 44. The drainage tank 44 has a V-shaped water guide plate 45. A drain pipe 46 is connected to the lowest point of the casing. The drain pipe 46 is S-shaped, which can effectively prevent wastewater and exhaust gas from flowing back. The other end of the drain pipe 46 is connected to the support plate 42, so that the wastewater enters the wastewater treatment tank 43 through the V-shaped water guide plate 45 and the drain pipe 46. The height of the casing 41 is higher than the height of the operating table 3. A wastewater pouring port 47 and an exhaust gas intake port 48 are opened on the side of the casing 41 near the operating table 3. A fixing plate 49 is also provided on the upper part of the interior of the casing 41. An exhaust gas treatment component 5 for treating exhaust gas is provided on the upper part of the fixing plate 49.

[0044] The exhaust gas treatment assembly 5 includes multiple sets of filter plates 51 disposed above the fixed plate 49. A gas discharge pipe 52 is provided on the back of the housing 41. A cover plate 53 is hinged to the top of the housing 41. A rubber sealing gasket 54 is provided on the inner side of the cover plate 53. The cover plate 53 is used to seal the wastewater pouring port 47 and the exhaust gas intake port 48 to prevent exhaust gas leakage.

[0045] The exhaust gas treatment component 5 operates at different power levels depending on the environment. For example, it can maintain full power during experiments and low power during non-experimental periods.

[0046] During use, wastewater and exhaust gas enter the treatment mechanism 4 and exhaust gas treatment component 5 through the wastewater pouring port 47 and exhaust gas intake port 48 on the operating platform 3. Inside the treatment mechanism 4 and exhaust gas treatment component 5, the wastewater is guided through the V-shaped water guide plate 45 to the drain pipe 46 and then enters the wastewater treatment tank 43 for treatment.

[0047] The storage box 31 inside the operating table 3 stores biological packing material, which is used for microbial degradation of organic matter in wastewater. The addition of biological packing material is adjusted according to the different wastewater volumes to maintain the nutrient supply and activity of microorganisms.

[0048] When conducting experiments on the operating table 3, a certain amount of waste gas may be generated. Open the cover plate 53, which is set at an angle above the operating table 3, similar to an integrated range hood. During the operation of the waste gas treatment component 5, the waste gas can be drawn in from the waste gas intake port 48 and then filtered through multiple sets of filter plates 51 to meet the emission standards. The waste gas is then discharged through the gas exhaust pipe 52 to prevent the generation of toxic gases during the experiment from being inhaled by the experimenters and causing poisoning. At the same time, the discharged waste gas can also meet environmental protection standards.

[0049] The device is designed with an integrated treatment system that can treat wastewater and waste gas simultaneously, ensuring that different forms of waste generated in the laboratory are effectively treated.

[0050] Example 2

[0051] Combination Figure 4 and Figure 9 This embodiment is an improvement based on Embodiment 1.

[0052] Biological treatment methods require the addition of biological packing material periodically, depending on the wastewater volume, to ensure a sufficient nutrient supply for the microorganisms and maximize their activity. Fluctuations in wastewater volume can lead to varying microbial burdens. When treating high volumes of wastewater, the frequency of adding biological packing material needs to be increased to ensure that the microorganisms can adapt to and degrade more wastewater.

[0053] A telescopic mechanism 6 is provided above the support plate 42;

[0054] The telescopic mechanism 6 includes a cylindrical cavity shell 61. A telescopic rubber sleeve 62 is provided inside the cavity shell 61. A support rod 63 is connected to one side of the telescopic rubber sleeve 62. A telescopic spring 64 is also provided on the side of the telescopic rubber sleeve 62 near the support rod 63. One end of the telescopic spring 64 abuts against the telescopic rubber sleeve 62, and the other end of the telescopic spring 64 abuts against the inner wall of the cavity shell 61. An air inlet 65 is also provided on the cavity shell 61. An air pipe 66 is connected to the air inlet 65. The other end of the air pipe 66 passes through the support plate 42 and communicates with the wastewater treatment tank 43.

[0055] A discharge pipe 7 is installed through the partition 2. The discharge pipe 7 is inclined. One end of the discharge pipe 7 is connected to the bottom side of the storage box 31. The other end of the discharge pipe 7 is installed through the wastewater treatment box 43. The discharge pipe 7 is inclined. An elongated hole 71 is opened on the upper side of the discharge pipe 7. A baffle 72 is slidably inserted into the elongated hole 71.

[0056] The upper end of the support rod 63 is connected to a connecting rod 73 for controlling the movement of the baffle 72. The upper end of the connecting rod 73 is connected to a frame 74. The frame 74 is sleeved on the outside of the feed tube 7, and one side of the frame 74 is connected to the baffle 72.

[0057] Please see Figure 11 The inside of the feed tube 7 is provided with a spring sheet 75, and the spring sheet 75 extends through the upper wall of the feed tube 7 to the side of the baffle 72. The side of the baffle 72 is provided with protrusions 76 at intervals. When the protrusions 76 move, they contact the spring sheet 75 to drive the vibration of the spring sheet 75.

[0058] It should be noted that the spring 75 penetrates the upper wall of the feed tube 7, and the spring 75 is connected to the feed tube 7 by a connecting spring, which makes the vibration amplitude of the spring 75 larger. When the baffle 72 moves, the protrusion 76 contacts the spring 75, causing the spring 75 to vibrate. The spring 75 vibrates inside the feed tube 7, which can disperse the biological packing material inside the feed tube 7 and prevent caking as much as possible.

[0059] The baffle 72 is used to control the biological packing material to enter the wastewater treatment tank 43 through the feed pipe 7. When the baffle 72 moves upward, it opens the feed pipe 7 to allow the biological packing material to enter the wastewater treatment tank 43 through the feed pipe 7. When the baffle 72 moves downward, it closes the feed pipe 7 to prevent the biological packing material from continuously entering the wastewater treatment tank 43.

[0060] Specifically, the telescopic mechanism 6 is related to the exhaust gas emission inside the wastewater treatment tank 43. When the amount of exhaust gas inside the wastewater treatment tank 43 increases, causing the air pressure inside the wastewater treatment tank 43 to rise, the exhaust gas enters the cavity shell 61 through the air pipe 66, squeezing the telescopic rubber sleeve 62, causing the support rod 63 to move up and down.

[0061] A connecting rod 73 is connected to the upper end of the support rod 63, and a frame 74 is connected to the upper end of the connecting rod 73. The frame 74 is fitted onto the outside of the feed pipe 7 and connected to the baffle 72. Through its connection with the connecting rod 73 and the frame 74, the baffle 72 can move up and down in response to changes in the pressure of the exhaust gas.

[0062] The baffle 72 is used to control the entry of biological packing material into the wastewater treatment tank 43 through the feed pipe 7. When the amount of waste gas increases, the support rod 63 moves upward, causing the baffle 72 to open the feed pipe 7, thereby allowing more biological packing material to enter the wastewater treatment tank 43.

[0063] The introduction of the telescopic mechanism 6 makes the wastewater treatment device more adaptable. When treating high wastewater volumes, the device can promptly increase the frequency of biological filler addition to ensure sufficient nutrient supply and activity for microorganisms; it can also adjust the amount of biological filler added in real time to ensure that the nutrient supply to microorganisms matches the characteristics of the current wastewater, thereby maximizing microbial activity and improving wastewater degradation efficiency. Adjusting the addition of biological filler according to changes in wastewater volume allows for more effective resource utilization, reduces waste, and improves the energy efficiency of the treatment system.

[0064] Example 3

[0065] Combination Figure 4 and Figure 9 This embodiment is an improvement based on Embodiment 1 and Embodiment 2.

[0066] During wastewater treatment within the biological packing material in the wastewater treatment tank 43, the biogas produced by the chemical reaction causes a significant increase in internal pressure. Given that the wastewater treatment tank 43 is typically in a relatively enclosed environment, this gradual increase in pressure may exacerbate safety hazards. Of particular concern is the flammable and explosive nature of biogas, which increases the potential risk of fire and explosion. Therefore, effective measures must be taken during wastewater treatment to regulate and release the waste gas, ensuring the safe and controllable operation of the wastewater treatment tank 43.

[0067] To address the aforementioned issues, an exhaust pipe 431 is installed on the wastewater treatment tank 43, penetrating the support plate 42, to prevent excessive internal air pressure. The other end of the exhaust pipe 431 extends through the housing 41 to the fixed plate 49, and the other outlet end of the exhaust pipe 431 is located on the exhaust gas treatment assembly 5. The exhaust gas discharged from the wastewater treatment tank 43 is further treated by the exhaust gas treatment assembly 5. This design aims to prevent excessive internal air pressure in the wastewater treatment tank 43 while simultaneously further treating the exhaust gas through the exhaust gas treatment assembly 5.

[0068] If the exhaust pipe 431 continuously discharges the waste gas from the wastewater treatment tank 43 into the waste gas treatment component 5, since the waste gas treatment component 5 does not always operate at full power, there may be cases where the waste gas is not completely treated. This can easily lead to an increase in the concentration of biogas accumulated in the waste gas treatment component 5, thereby increasing the risk of explosion and fire.

[0069] A push valve 8 is installed on the side of the exhaust pipe 431 near the support rod 63;

[0070] The push valve 8 includes a valve body installed on the exhaust pipe 431 and a valve seat disposed inside the valve body. The valve body also contains a valve core. One side of the valve core is connected to a valve stem 81, and the other end of the valve stem 81 is connected to a pressure block 9. One side of the pressure block 9 is provided with a first oblique surface 91. A return spring 92 is sleeved on the valve stem 81. One end of the return spring 92 abuts against the pressure block 9, and the other end of the return spring 92 abuts against the valve body, so that the valve core can be easily reset.

[0071] A pressing block 10 is also fixedly connected to the side of the support rod 63. The pressing block 10 is provided with a second oblique surface 101 that matches the first oblique surface 91. When the pressing block 10 moves upward, it is used to drive the movement of the pressing block 9, thereby controlling the opening and closing of the pressing valve 8.

[0072] During the movement of the support rod 63, the pressing block 10 moves upward, driving the pressure block 9 to move, thereby controlling the opening and closing state of the pressing valve 8. When the support rod 63 moves, the second oblique surface 101 on the pressing block 10 matches the first oblique surface 91 on the pressure block 9, causing the valve rod 81 to move by pressing, thereby opening the pressing valve 8.

[0073] This allows the high-pressure exhaust gas generated inside the wastewater treatment tank 43 to be discharged into the exhaust gas treatment component 5 through the exhaust pipe 431. The exhaust gas then undergoes purification through the exhaust gas treatment component 5, passing through the filter plate 51 and other steps, before being safely discharged.

[0074] Intermittent exhaust can effectively reduce the concentration of biogas accumulated in the exhaust gas treatment component 5, thereby reducing the risk of explosion and fire and minimizing potential dangers.

[0075] Example 4

[0076] Combination Figure 7 and Figure 10 This embodiment is an improvement based on Embodiments 1, 2 and 3.

[0077] Wastewater enters the shell 41 and V-shaped water guide plate 45 through the wastewater pouring port 47, and is then discharged into the wastewater treatment tank 43 through the drain pipe 46. After a long period of operation, a large amount of impurities will accumulate inside the shell 41 and V-shaped water guide plate 45.

[0078] A cleaning mechanism 11 is provided inside the housing 41 between the fixed plate 49 and the V-shaped water guide plate 45;

[0079] The cleaning mechanism 11 includes a rectangular frame 111 disposed inside the housing 41. A cleaning brush is disposed on the side of the rectangular frame 111 near the housing 41. Two sets of sliding grooves 112 are provided on the inner wall of the housing 41. Sliding strips 113 are slidably connected in the two sets of sliding grooves 112. The side of the sliding strips 113 is fixedly connected to the rectangular frame 111. A rack 114 is also provided on the sliding strips 113. A drive mechanism 12 is also installed on the exhaust pipe 431.

[0080] The drive mechanism 12 includes a mounting housing 121 mounted on the exhaust pipe 431. The mounting housing 121 is provided with an air inlet 122 and an air outlet 123 connected to the exhaust pipe 431. Two sets of rotating shafts 124 are installed inside the mounting housing 121. Rotors 125 are mounted on the two sets of rotating shafts 124. The rotation of the rotors 125 is driven by the gas in the exhaust pipe 431. A rotating rod 126 is coaxially connected to the rotating shaft 124. A gear 127 is provided at the end of the rotating rod 126. The gear 127 is meshed with a rack 114 to control the movement of the rectangular frame 111.

[0081] A reset assembly 13 for resetting the rectangular frame 111 is installed at the corner of the inner wall of the housing 41. The reset assembly 13 includes a long rectangular tube 131 installed at the corner of the inner wall of the housing 41. A guide rod 132 is provided inside the rectangular tube 131. A guide hole 133 matching the guide rod 132 is opened on the rectangular frame 111. A tension spring 134 is installed inside the rectangular tube 131. One end of the tension spring 134 is connected to the rectangular frame 111.

[0082] The working process of cleaning agency 11:

[0083] During the wastewater treatment process, the cleaning mechanism 11 and the drive mechanism 12 are in standby mode.

[0084] The exhaust system on the exhaust pipe 431 remains closed, and the exhaust gas does not enter the mounting housing 121 through the air inlet 122.

[0085] When the air pressure inside the wastewater treatment tank 43 increases, the pressure valve 8 opens, causing the exhaust pipe 431 to start venting. The exhaust gas from the exhaust pipe 431 first enters the mounting housing 121 through the air inlet 122, driving the rotor 125 to rotate.

[0086] The rotation of rotor 125 causes the rotating rod 126 on the rotating shaft 124 to rotate as well. The meshing design of gear 127 and rack 114 causes rectangular frame 111 to move down along the inner wall of slide groove 112, driving rectangular frame 111 to slide and clean, ensuring that the cleaning brush can cover the inner surface of housing 41, effectively cleaning the attached impurities and preventing the long-term accumulation of a large number of impurities.

[0087] When the air pressure in the wastewater treatment tank 43 returns to normal, the press valve 8 closes and the exhaust pipe 431 is closed. At this time, due to the tension of the tension spring 134, the rectangular frame 111 moves upward to the initial position. It should be noted that the rectangular frame 111 moves along the guide rod 132.

[0088] This facilitates regular cleaning of the interior of the housing 41, which helps maintain the efficient operation and long lifespan of the equipment.

[0089] Because the inner wall of the housing 41 and the V-shaped water guide plate 45 are irregularly shaped, the cleaning mechanism 11 is prone to dead corners during the cleaning process.

[0090] This application provides cleaning components 14 for cleaning the V-shaped water guide plate 45 on both sides below the rectangular frame 111;

[0091] The cleaning component 14 includes a U-shaped fixing plate 141 connected below the rectangular frame 111. A wiping plate 142 is rotatably connected in the U-shaped groove of the U-shaped fixing plate 141. The inner side wall of the wiping plate 142 is connected to the U-shaped fixing plate 141 by a tension spring.

[0092] The wiping plate 142 moves onto the V-shaped water guide plate 45 and moves along the surface of the V-shaped water guide plate 45;

[0093] A V-shaped cleaning plate 143 is also provided below the rectangular frame 111.

[0094] When the cleaning mechanism 11 is activated, the wiping plate 142 within the U-shaped groove of the U-shaped fixing plate 141 is rotatably connected. The force provided by the tension spring ensures that the wiping plate 142 is always subjected to moderate tension, keeping it firmly against the surface of the V-shaped water guide plate 45, enabling effective cleaning even on irregularly shaped surfaces. The design of the V-shaped cleaning plate 143 helps provide additional support on irregularly shaped surfaces of the housing 41, ensuring that no dead-end areas are missed.

[0095] Example 5

[0096] This application also discloses a method for treating laboratory wastewater and exhaust gas using a treatment device, the method being as follows:

[0097] Prepare the biological packing material and place it into storage box 31;

[0098] Experimental wastewater is poured out through wastewater discharge port 47. The wastewater enters wastewater treatment tank 43 through V-shaped guide plate 45 and drain pipe 46, where it is treated and purified by biological packing material.

[0099] When conducting experiments on the operating table 3, exhaust gas is generated. When the cover plate 53 is opened, the exhaust gas enters the exhaust gas treatment component 5 through the exhaust gas intake port 48 for treatment.

[0100] When more wastewater is dumped, more biological packing material is needed. When the wastewater treatment tank 43 treats wastewater, more waste gas is generated. At the same time, the increase in waste gas in the wastewater treatment tank 43 increases the air pressure inside the wastewater treatment tank 43. The waste gas will enter the cavity shell 61 through the air pipe 66, which will squeeze the telescopic rubber sleeve 62. When the telescopic rubber sleeve 62 moves, it will drive the support rod 63 to move. The movement of the support rod 63 is used to drive the movement of the baffle 72, thereby opening the feed pipe 7 and allowing more biological packing material to enter the wastewater treatment tank 43 to adapt to large water volume treatment.

[0101] Additionally, the movement of the support rod 63 can drive the extrusion block 10 to move upward. The second oblique surface 101 on the extrusion block 10 matches and extrudes with the first oblique surface 91 on the pressure block 9, thereby driving the valve rod 81 to move. The movement of the valve rod 81 causes the press valve 8 to open, and the high-pressure exhaust gas in the wastewater treatment tank 43 is discharged to the exhaust gas treatment component 5 through the exhaust pipe 431. After being treated by the filter plate 51, it is purified and then discharged.

[0102] The drive mechanism 12 installed on the exhaust pipe 431 is used to drive the movement of the cleaning mechanism 11 and the cleaning component 14, so that the cleaning mechanism 11 and the cleaning component 14 clean the inner wall of the housing 41 and prevent impurities from accumulating on the inner wall of the housing 41.

[0103] After the experiment, close the cover plate 53 to seal the wastewater pouring port 47 and the exhaust gas intake port 48 to prevent exhaust gas from leaking into the laboratory.
