Description

Technical Field

[0001] This application relates to the field of odor treatment equipment technology, and in particular to an odor treatment device for a hazardous waste temporary storage facility. Background Technology

[0002] Hazardous waste temporary storage facilities serve as centralized locations for storing various types of hazardous waste (such as chemical waste, medical waste, and waste solvents). Due to the reactive chemical properties of the waste itself, these facilities are prone to generating large amounts of odorous gases during temporary storage through volatilization, decomposition, fermentation, or chemical reactions. These odorous gases are complex in composition, typically containing volatile organic compounds, hydrogen sulfide, ammonia, hydrogen chloride, and other pollutants. They not only have a strong, pungent odor but also affect the surrounding environment and the health of workers. Improper handling can pose a serious threat to the ecological environment and human safety.

[0003] In existing technologies, the industry mostly uses fixed-location single purification devices, such as activated carbon adsorption devices and alkaline spray devices, for odor treatment in hazardous waste temporary storage facilities. However, these devices have obvious limitations: on the one hand, fixed-installation treatment devices can only collect and treat odors in the surrounding local area, making it difficult to cover the entire space of the temporary storage facility, easily creating blind spots in collection and purification, resulting in the diffusion of some odor gases and poor treatment effect; on the other hand, single purification methods are not targeted enough for odor gases with complex components. For example, activated carbon adsorption has limited effect on removing acidic gases, and alkaline spray devices have weak purification capabilities for organic pollutants, making it difficult to achieve comprehensive and efficient odor removal.

[0004] Therefore, we propose an odor treatment device for a hazardous waste temporary storage facility to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide an odor treatment device for a hazardous waste temporary storage facility, which can achieve comprehensive and efficient purification of odor gases in the hazardous waste temporary storage facility.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an odor treatment device for a hazardous waste temporary storage facility, comprising a crossbeam suspended and fixed inside the hazardous waste temporary storage facility, a guide rail fixedly installed at the bottom of the crossbeam, a rack fixedly installed at the bottom of the guide rail, guide grooves opened on both sides of the guide rail, guide seats slidably installed in both guide grooves, a U-shaped seat fixedly installed at the bottom of the two guide seats, an odor treatment box fixedly installed at the bottom of the U-shaped seat, and a purification chamber one and a purification chamber two opened inside the odor treatment box, the purification chamber one being used to hold activated carbon granules, and the purification chamber two being used to hold an alkaline solution, thereby treating the odor. A suction fan is fixedly installed at the bottom of the odor treatment box. A four-way pipe is fixedly connected to the suction end of the suction fan. Each of the three air inlets of the four-way pipe is fixedly connected to a suction hood. An L-shaped air supply pipe is fixedly connected to the exhaust end of the suction fan. The top end of the L-shaped air supply pipe extends into the first purification chamber. A U-shaped air supply pipe is fixedly installed on the top of the odor treatment box. The two ends of the U-shaped air supply pipe extend into the first purification chamber and the second purification chamber, respectively. A drive assembly is installed on the U-shaped seat. The drive assembly is used to control the linear movement of the U-shaped seat on the guide rail. A stirring assembly is installed on the odor treatment box. The stirring assembly is used to stir the movement of activated carbon particles in the first purification chamber and the movement of alkaline solution in the second purification chamber.

[0007] By adopting the above technical solution, the activated carbon particles in the first purification chamber can efficiently adsorb organic pollutants and some inorganic pollutants in the odor gas, thereby achieving the purpose of purifying the gas. The alkaline solution in the second purification chamber can specifically neutralize acidic odor components, causing the acidic components in the odor gas (such as hydrogen chloride, sulfuric acid mist, hydrogen sulfide, etc.) to undergo a neutralization reaction with the alkaline solution, thus removing the odor. Under the synergistic effect of the two, the removal effect of complex odor components can be greatly improved.

[0008] A further configuration of this application is as follows: the drive assembly includes a drive shaft, a gear, a base, and a motor. The drive shaft is rotatably mounted inside the U-shaped base. The gear is fixedly sleeved on the drive shaft and meshes with a rack.

The left end of the drive shaft extends outside the U-shaped base and is fixedly connected to the output shaft end of the motor.

[0009] By adopting the above technical solution, the motor drives the horizontal shaft and gears to rotate. Under the meshing transmission of the gears and racks, the U-shaped seat can move smoothly along the guide rail, driving the odor treatment box to move linearly within the temporary storage area. With the help of the four-way pipe connected to the suction fan and three suction hoods, the odors in different areas of the hazardous waste temporary storage area can be dynamically and comprehensively collected and deodorized, avoiding the problem of blind spots in odor gas collection and purification, and significantly improving the efficiency and scope of odor collection and purification.

[0010] A further configuration of this application is as follows: the stirring assembly includes a first horizontal rotating shaft, multiple stirring rods, a second horizontal rotating shaft, and two stirring frames. The first horizontal rotating shaft is rotatably installed inside the first purification chamber. The multiple stirring rods are all fixedly installed on the first horizontal rotating shaft and are evenly distributed. The right end of the first horizontal rotating shaft extends into the second purification chamber. The second horizontal rotating shaft is fixedly installed on the right end of the first horizontal rotating shaft. The second horizontal rotating shaft is located in front of the U-shaped gas transmission pipe. The two stirring frames are all fixedly installed on the second horizontal rotating shaft and are symmetrically arranged.

[0011] By adopting the above technical solution, the first horizontal rotating shaft drives multiple stirring rods to rotate, which can agitate the activated carbon particles in the first purification chamber, increasing the contact area between the activated carbon particles and the odor gas; the second horizontal rotating shaft drives two stirring racks to rotate, which can agitate the alkaline solution in the second purification chamber, increasing the contact area between the alkaline solution and the odor gas, allowing the alkaline solution to fully contact the gas, and improving the rate and completeness of the neutralization reaction.

[0012] A further configuration of this application is as follows: the stirring assembly further includes a main pulley, a secondary pulley, and a belt. The main pulley is fixedly sleeved on the drive shaft, the left end of the first horizontal shaft extends to the outside of the odor treatment box, the secondary pulley is fixedly sleeved on the left end of the first horizontal shaft, and the belt is tensioned and sleeved on the main pulley and the secondary pulley.

[0013] By adopting the above technical solution, the transmission action of the main pulley, the auxiliary pulley, and the belt can be used to control the simultaneous rotation of the drive shaft, the first horizontal shaft, and the second horizontal shaft.

[0014] A further feature of this application is that an exhaust pipe is fixedly installed on the top of the odor treatment box, the exhaust pipe is connected to the purification chamber, and a demister is fixedly installed inside the exhaust pipe.

[0015] By adopting the above technical solution, the exhaust pipe is used to discharge the purified gas, and the demister can effectively remove the liquid droplets carried in the purified gas.

[0016] A further provision of this application is that an L-shaped reinforcing plate is fixedly installed on the right outer wall of the U-shaped seat, and the bottom of the L-shaped reinforcing plate is fixedly connected to the top of the odor treatment box.

[0019] By adopting the above technical solution, the alkaline solution can be easily added to the second purification chamber using the liquid addition pipe and end cap, and the alkaline solution in the second purification chamber can be easily discharged using the residual discharge pipe and residual discharge valve, so as to facilitate the replacement of the alkaline solution.

[0020] A further feature of this application is that a cleaning port is provided on the front inner wall of the purification chamber 2, a material port is provided on the front inner wall of the purification chamber 1, and a sealing cover plate 1 and a sealing cover plate 2 are fixedly installed on the front outer wall of the odor treatment box by screws.

[0028] 2. This application utilizes the activated carbon particles contained in the first purification chamber, which, due to their porous structure, can physically adsorb organic pollutants and some inorganic pollutants in the odorous gas, thus initially purifying the gas and removing the odor.

The gas, after dual purification, is discharged through the exhaust pipe at the top of the odor treatment box. The demister in the exhaust pipe can remove liquid droplets carried in the gas, preventing secondary pollution.

Detailed Implementation

[0035] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides an odor treatment device for a hazardous waste temporary storage facility, comprising a crossbeam 1 suspended and fixed inside the hazardous waste temporary storage facility, a guide rail 2 fixedly installed at the bottom of the crossbeam 1, a rack 3 fixedly installed at the bottom of the guide rail 2, guide grooves 4 on both sides of the guide rail 2, guide seats 5 slidably installed in both guide grooves 4, a U-shaped seat 6 fixedly installed at the bottom of both guide seats 5, an odor treatment box 7 fixedly installed at the bottom of the U-shaped seat 6, a purification chamber 8 and a purification chamber 9 opened inside the odor treatment box 7, the purification chamber 8 is used to hold activated carbon granules, and the purification chamber 9 is used to hold an alkaline solution, a suction fan 10 fixedly installed at the bottom of the odor treatment box 7, a four-way pipe 11 fixedly connected to the suction end of the suction fan 10, a suction hood 12 fixedly connected to each of the three air inlets of the four-way pipe 11, and an L-shaped conveyor fixedly connected to the discharge end of the suction fan 10. The top of the L-shaped gas pipe 13 extends into the purification chamber 8. A U-shaped gas pipe 14 is fixedly installed on the top of the odor treatment box 7. The two ends of the U-shaped gas pipe 14 extend into the purification chamber 8 and the purification chamber 9, respectively. The activated carbon particles in the purification chamber 8 can efficiently adsorb organic pollutants and some inorganic pollutants in the odor gas, adsorbing the odor substances onto the surface of the activated carbon particles, thereby achieving the purpose of purifying the gas. The alkaline solution in the purification chamber 9 can specifically neutralize acidic odor components, causing the acidic components in the odor gas (such as hydrogen chloride, sulfuric acid mist, hydrogen sulfide, etc.) to undergo a neutralization reaction with the alkaline solution, converting them into harmless salt and water, thereby removing the odor. With the synergistic effect of the two, the removal effect of complex odor components can be greatly improved. Compared with a single treatment method, it is more adaptable to the diverse odor sources in the hazardous waste temporary storage.

[0037] In this embodiment, a drive assembly is provided on the U-shaped base 6. The drive assembly is used to control the linear movement of the U-shaped base 6 on the guide rail 2. The drive assembly includes a drive horizontal shaft 15, a gear 16, a base 17, and a motor 18. The drive horizontal shaft 15 is rotatably mounted inside the U-shaped base 6. The gear 16 is fixedly sleeved on the drive horizontal shaft 15 and meshes with the rack 3. The base 17 is fixedly mounted on the left outer wall of the U-shaped base 6. The motor 18 is fixedly mounted on the base 17. The motor 18 is a reversible motor. The left end of the drive horizontal shaft 15 extends outside the U-shaped base 6 and connects with the guide rail 2. The output shaft of motor 18 is fixedly connected. By using motor 18 to drive the horizontal shaft 15 and gear 16 to rotate, under the meshing transmission action of gear 16 and rack 3, the U-shaped seat 6 can move smoothly along the guide rail 2, driving the odor treatment box 7 to move linearly in the temporary storage room. With the help of the four-way pipe 11 connected to the suction fan 10 and the three suction hoods 12, the odor in different areas of the hazardous waste temporary storage room can be dynamically and comprehensively collected and deodorized, avoiding the problem of blind spots in odor gas collection and purification, and significantly improving the efficiency and scope of odor collection and purification.

[0038] In this embodiment, the odor treatment box 7 is equipped with a stirring assembly. The stirring assembly is used to stir the movement of activated carbon particles in the first purification chamber 8 and the movement of alkaline solution in the second purification chamber 9. The stirring assembly includes a horizontal rotating shaft 19, multiple stirring rods 20, a second horizontal rotating shaft 21, and two stirring frames 22. The horizontal rotating shaft 19 is rotatably installed in the first purification chamber 8. The multiple stirring rods 20 are all fixedly installed on the horizontal rotating shaft 19 and are evenly distributed. The right end of the horizontal rotating shaft 19 extends into the second purification chamber 9. The second horizontal rotating shaft 21 is fixedly installed on the horizontal rotating shaft 19. At the right end of shaft 19, horizontal rotating shaft 21 is located in front of the U-shaped gas supply pipe 14. Two stirring racks 22 are fixedly installed on horizontal rotating shaft 21 and arranged symmetrically. The stirring assembly also includes a main pulley 23, a secondary pulley 24, and a belt 25. The main pulley 23 is fixedly sleeved on the drive horizontal shaft 15. The left end of horizontal rotating shaft 19 extends outside the odor treatment box 7. The secondary pulley 24 is fixedly sleeved on the left end of horizontal rotating shaft 19. The belt 25 is tensioned and sleeved on the main pulley 23 and the secondary pulley 24. The stirring assembly utilizes the main pulley 23... The transmission action of the auxiliary pulley 24 and belt 25 controls the simultaneous rotation of the drive shaft 15, the first horizontal shaft 19, and the second horizontal shaft 21. The first horizontal shaft 19 drives the multiple stirring rods 20 on it to rotate, which agitates the activated carbon particles in the purification chamber 8, increasing the contact area between the activated carbon particles and the odor gas. This effectively avoids the local adsorption saturation of the activated carbon particles, extending their service life and making fuller use of the activated carbon particles. It also enhances the physical adsorption and odor removal purification effect of the odor gas. The second horizontal shaft 21 drives the two stirring racks 22 on it to rotate, which agitates the alkaline solution in the purification chamber 9, increasing the contact area between the alkaline solution and the odor gas. This allows the alkaline solution to fully contact the gas, improving the rate and completeness of the neutralization reaction, and further enhancing the purification effect of the odor gas. It should be noted that the activated carbon particles are high-quality granular activated carbon purchased from the market (such as models processed with special technology), which have good compressive strength and are not easily broken during the stirring process.

[0039] In this embodiment, an exhaust pipe 26 is fixedly installed on the top of the odor treatment box 7. The exhaust pipe 26 is connected to the purification chamber 9. A demister 27 is fixedly installed inside the exhaust pipe 26. The exhaust pipe 26 is used to discharge the purified gas. The demister 27 can effectively remove the liquid droplets carried in the purified gas and prevent the air in the hazardous waste temporary storage room from being polluted secondary.

[0040] In this embodiment, an L-shaped reinforcing plate 28 is fixedly installed on the right outer wall of the U-shaped base 6. The bottom of the L-shaped reinforcing plate 28 is fixedly connected to the top of the odor treatment box 7. The design of the L-shaped reinforcing plate 28 enhances the firmness of the connection between the odor treatment box 7 and the U-shaped base 6.

[0041] In this embodiment, an inclined liquid filling pipe 29 is fixedly installed on the top right side of the odor treatment box 7. The liquid filling pipe 29 is connected to the purification chamber 2 9. An end cap 30 is threaded onto the top of the liquid filling pipe 29. A residual discharge pipe 31 is fixedly installed on the bottom right side of the odor treatment box 7. The residual discharge pipe 31 is connected to the purification chamber 2 9. A residual discharge valve 32 is fixedly installed on the residual discharge pipe 31. The design of the liquid filling pipe 29 and the end cap 30 facilitates the addition of alkaline solution into the purification chamber 2 9. The design of the residual discharge pipe 31 and the residual discharge valve 32 facilitates the discharge of alkaline solution from the purification chamber 2 9, so as to facilitate the replacement of alkaline solution.

[0042] In this embodiment, a cleaning port is provided on the front inner wall of purification chamber 2 9, and a material inlet is provided on the front inner wall of purification chamber 1 8. A sealing cover 1 33 and a sealing cover 2 34 are fixedly installed on the front outer wall of odor treatment box 7 by screws. The sealing cover 1 33 is adapted to the cleaning port, and the sealing cover 2 34 is adapted to the material inlet. The design of the sealing cover 1 33 and the cleaning port facilitates the cleaning and maintenance of purification chamber 2 9. The design of the sealing cover 2 34 and the material inlet facilitates the placement of activated carbon particles into purification chamber 1 8 and facilitates the replacement of activated carbon particles. Both the sealing cover 1 33 and the sealing cover 2 34 are made of transparent tempered glass, which allows for easy and intuitive viewing of the interior of purification chamber 1 8 and purification chamber 2 9.

[0043] In this embodiment, multiple evenly distributed hangers 35 are fixedly installed on the top of the crossbeam 1. The design of multiple hangers 35 ensures the stability of the entire device in hoisting and fixing, and can reliably hoist and fix the device at the required height position in the hazardous waste temporary storage facility as needed.

[0044] In this embodiment, both the end of the L-shaped gas supply pipe 13 located in the purification chamber 8 and the end of the U-shaped gas supply pipe 14 located in the purification chamber 8 are fixedly equipped with baffles. The baffles prevent activated carbon particles from entering the L-shaped gas supply pipe 13 and the U-shaped gas supply pipe 14 and causing blockage, thus ensuring the smooth operation of the device.

[0045] In this embodiment, both the suction fan 10 and the motor 18 can be purchased on the market, and their wiring connection and control methods are mature technologies in the field and have been fully disclosed, so they will not be described in detail here.

[0046] With the above structure, the working principle of the odor treatment device for a hazardous waste temporary storage facility provided in this application is as follows:

[0047] Remove the sealing cover plate 2 34, pour an appropriate amount of activated carbon granules into the purification chamber 1 8 from the material inlet, then put the sealing cover plate 2 34 back onto the odor treatment box 7 to seal the material inlet, unscrew the end cap 30, pour an appropriate amount of alkaline solution into the purification chamber 2 9 from the liquid adding pipe 29, and then tighten the end cap 30 on the top of the liquid adding pipe 29.

[0048] When treating odors in the hazardous waste temporary storage facility, the suction fan 10 and motor 18 are controlled to operate. After the motor 18 starts, its output shaft drives the drive shaft 15 to rotate. The gear 16 fixed on the drive shaft 15 rotates accordingly. Since the gear 16 meshes with the rack 3 at the bottom of the guide rail 2, under the action of meshing transmission, the U-shaped seat 6 slides smoothly along the guide groove 4 of the guide rail 2 through the guide seats 5 on both sides, thereby driving the odor treatment box 7 at the bottom to move linearly in the hazardous waste temporary storage facility (the motor 18 can rotate in both directions and can move back and forth). At the same time, when the suction fan 10 is running, the three suction hoods 12 connected by the four-way pipe 11 suck in the odor gas from different areas in the hazardous waste temporary storage facility, realizing dynamic and comprehensive collection of odors in the facility and avoiding blind spots in fixed location collection.

[0049] The suction fan 10 first delivers the odorous gas into the purification chamber 8 through the L-shaped gas delivery pipe 13. The activated carbon particles contained in the purification chamber 8 utilize their porous structure to physically adsorb organic pollutants and some inorganic pollutants in the odorous gas, thus initially purifying the gas and removing the odor. The gas treated by the purification chamber 8 then enters the purification chamber 9 through the U-shaped gas delivery pipe 14. The alkaline solution in the purification chamber 9 neutralizes the acidic components (such as hydrogen chloride and hydrogen sulfide) in the gas, converting them into harmless salt and water, thus achieving secondary deep purification of the gas and further removing the odor.

[0050] Simultaneously, when the drive shaft 15 rotates, the main pulley 23 on it drives the auxiliary pulley 24 to rotate through the belt 25, which in turn causes the first horizontal shaft 19 to rotate. The multiple stirring rods 20 on the first horizontal shaft 19 stir the activated carbon particles in the first purification chamber 8, increasing the contact area between the activated carbon and the odor gas, avoiding local adsorption saturation, and improving the adsorption and odor removal efficiency and effect. At the same time, the second horizontal shaft 21 at the right end of the first horizontal shaft 19 drives the two stirring racks 22 to rotate, stirring the alkaline solution in the second purification chamber 9, promoting full contact between the alkaline solution and the gas, accelerating the neutralization reaction rate, and ensuring sufficient purification.

[0051] The gas, after undergoing dual purification, is discharged through the exhaust pipe 26 at the top of the odor treatment box 7. The demister 27 inside the exhaust pipe 26 can remove liquid droplets carried in the gas to prevent secondary pollution.
