Description

Technical Field

[0001] This invention belongs to the field of shampoo exhaust gas treatment, specifically referring to a shampoo production exhaust gas treatment device. Background Technology

[0002] The waste gas generated during shampoo processing mainly comes from chemical reactions, solvent evaporation, and raw material handling during the production process. Its components are mainly volatile organic compounds, including siloxanes and benzene compounds.

[0003] During shampoo production, harmful gases (such as formaldehyde, dioxane, and volatile organic compounds) are generated and must be purified by exhaust gas treatment equipment before being released. Currently, common spray towers use multiple sets of fan-shaped spray nozzles to spray a clean water mist to cover the waste gas flow area and avoid treatment dead zones. However, this design involves redundant nozzle arrangement to prevent spray dead zones, which not only increases equipment installation costs but also limits the actual treatment effect due to insufficient water mist coverage. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to fully treat the waste liquid generated in the shampoo production process. The present invention provides a shampoo production exhaust gas treatment device to at least partially solve the problems mentioned in the background art.

[0006] Furthermore, the spray device includes multiple sets of air-blowing components configured to blow air in a controllable direction.

[0007] Furthermore, multiple spray units for spraying are located directly above the blower unit.

[0008] Furthermore, the blowing assembly includes an air chamber that can blow airflow in the direction of the blowing assembly.

[0009] Furthermore, a Y-shaped flow divider is movably disposed inside the air chamber, and the Y-shaped flow divider is configured to change the direction of the airflow.

[0010] Furthermore, a first air deflector is located on one side of the air chamber and is configured to guide the direction of the airflow.

[0012] Furthermore, the blower assembly also includes a rotating shaft, a connecting bar, a control device, and a first servo motor.

[0013] Furthermore, the rotating shaft passes through the bottom of the Y-shaped flow divider and is movably disposed inside the air chamber.

A first servo motor is provided outside the control device. The first servo motor is connected to the inside of the connecting strip, and the first servo motor is configured to control the connecting strip to perform reciprocating deflection motion.

[0014] Furthermore, the blower assembly also includes a grille, a second servo motor, a motor rod, and a fan.

[0015] Furthermore, the air chamber is equipped with a grille, and a fan is located at the lower part of the grille. The bottom of the fan is connected to a motor rod, and a second servo motor is located below the motor rod. The second servo motor is configured to drive the fan to rotate.

[0016] Furthermore, the spray assembly also includes a spray sleeve, a water supply pipe, an output shaft, and a water supply hole.

[0017] Furthermore, the spray sleeve is located at one end of the second guide shroud and is positioned directly above the air blowing chamber. The spray sleeve has an output shaft inside, and the output shaft has a water supply pipe inside. The water supply pipe is connected to a cleaning agent for treating exhaust gas. The output shaft has multiple sets of water supply holes inside, which are used to spray cleaning water mist for cleaning.

[0018] Furthermore, the spraying device also includes a support vertical plate and a connecting plate.

[0019] Furthermore, the supporting vertical plate is disposed on the outside of the spray assembly, and the supporting vertical plate is connected to the blower assembly through a connecting plate.

[0022] Furthermore, the washing tower is equipped with a vortex device inside, and the lower part of the vortex device is equipped with an air inlet. The air inlet is connected to the waste gas generated during the shampoo production process. The vortex device causes the waste gas to rotate and increases its existence time in the washing tower. The vortex device is equipped with multiple sets of air outlet strips inside.

Therefore, they should not be construed as limitations on the embodiments.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown in the figure, an embodiment of the present invention proposes a shampoo production exhaust gas treatment device, including a pair of spray devices 1, each of the spray devices 1 including a blower assembly 3, a spray assembly 4, a support vertical plate 11, a connecting plate 12 and a support block 13.

[0042] The blower assembly 3 includes an air chamber 31, a grille 32, a Y-shaped flow divider 33, a first air guide shroud 34, a rotating shaft 35, a connecting strip 36, a control device 37, a first servo motor 38, a second servo motor 39, a motor rod 310, and a fan 311.

[0043] The spray assembly 4 includes a spray sleeve 41, a second guide shroud 42, a water supply pipe 43, an output shaft 44, a water supply hole 45, and a fixed shaft 46.

[0044] In this embodiment of the invention, a pair of spray devices 1 are arranged opposite to each other. Multiple sets of spray components 4 are provided inside each supporting vertical plate 11, and a blower component 3 is provided directly below each spray component 4. The blower component 3 is fixedly connected to the supporting vertical plate 11 via a connecting plate 12. The spray components 4 can spray out cleaning water mist with adsorption and washing capabilities. A second guide hood 42 is provided at the front end of the spray sleeve 41 to guide the water mist sprayed from the spray sleeve 41. An output shaft 44 is provided inside the spray sleeve 41, and multiple sets of water inlets 45 are opened inside the output shaft 44. A water pipe 43 is connected inside the output shaft 44, and the water pipe 43 is connected to the water inlets 45. A fixed shaft is provided on the other side of the spray sleeve 41. 46. ​​The fixed shaft 46 is fixed inside the support vertical plate 11. The fixed shaft 46 can restrict the movement of the spray sleeve 41. The water supply pipe 43 is connected to the water mist for cleaning wastewater. Since the water supply pipe 43 is connected to the water supply hole 45, the final cleaning water mist will be sprayed out from the water supply hole 45. The sprayed water mist will be restricted in movement by the second guide hood 42 and will move outward along the same plane of the second guide hood 42. At the same height outside the second guide hood 42, a set of spray components 4 is also set. The water mist sprayed from the other set will also be restricted in movement by the second guide hood 42. Finally, the cleaning water mist emitted by the two sets of oppositely set second guide hoods 42 will move relative to each other and form a cleaning barrier between the second guide hoods 42, and react and combine with the waste gas transported below.

[0045] A blowing assembly 3 is provided at the lower part of each spray assembly 4. The blowing chamber 31 is located directly below the spray sleeve 41 and can blow air in a controllable direction. The air blown out by the blowing chamber 31 is directed towards the spray sleeve 41. A Y-shaped diverter plate 33 is movably installed inside the blowing chamber 31. The cross-section of the Y-shaped diverter plate 33 is Y-shaped. A rotating shaft 35 is fixedly connected to the bottom of the Y-shaped diverter plate 33. The rotating shaft 35 passes through the inside of the Y-shaped diverter plate 33 and is movably connected to the outside of the blowing chamber 31. A connecting strip 36 is provided at the lower part of the rotating shaft 35. The connecting strip 36 is located inside the control device 37. A first servo motor 38 is provided outside the control device 37. A sliding groove is provided inside the control device 37. The first servo motor 38 passes through the control device 37 and is connected to the connecting strip 36. The first servo motor 38 can drive the connecting strip 36 to deflect and reciprocate along the sliding groove, thereby driving the Y-shaped diverter plate 33 to rotate along the rotating shaft 35.

[0046] A grille 32 is provided at the lower part of the Y-shaped diverter 33, and a fan 311 is provided at the lower part of the grille 32. The bottom of the fan 311 is fixed to the motor rod 310, and a second servo motor 39 is provided at the bottom of the motor rod 310. A control device 37 is fixed to one side of the second servo motor 39. The second servo motor 39 drives the motor rod 310 to rotate, which in turn drives the fan 311 to rotate. As the fan 311 rotates, the air chamber 31 will have the ability to blow air. Since the upper part of the Y-shaped diverter 33 is Y-shaped, the air blown out of the air chamber 31 will be spun by the Y-shaped diverter 33. By driving the Y-shaped diverter 33 to rotate at a suitable angle by the control device 37, the air chamber 31 can be controlled to blow air at a specific angle. A first The first guide shroud 34 is located directly below the second guide shroud 42, and the first guide shroud 34 and the second guide shroud 42 face the same direction. When the Y-shaped diverter 33 changes a specific angle, the air blown out of the air chamber 31 acts on the surface of the first guide shroud 34, and the air will move along the first guide shroud 34. The cleaning water mist sprayed from the spray sleeve 41 will appear between the first guide shroud 34 and the second guide shroud 42. Therefore, by changing the airflow blown out of the air chamber 31 through the Y-shaped diverter 33, the cleaning water mist will be driven to move horizontally along the direction of the second guide shroud 42. The above operation can make the cleaning water mist form a uniform water mist wall between the first guide shroud 34 and the second guide shroud 42, which is more conducive to the reaction with the exhaust gas and greatly improves the reaction efficiency.

[0047] The toxic gases that may be generated during shampoo production mainly include formaldehyde, dioxane, and volatile organic compounds (such as fragrances and solvent volatiles). Therefore, these exhaust gases need to be treated to render them harmless before being released into the atmosphere. Existing equipment generally uses a spray tower for spraying, usually with multiple sets of nozzles above the exhaust gas to spray cleaning water mist. Since the water mist sprayed from the nozzles is fan-shaped, multiple sets of nozzles are needed for redundancy to prevent dead zones during exhaust gas treatment. This not only increases the cost of installation, but also results in low efficiency of exhaust gas treatment in actual production. However, this invention uses an air blowing chamber 31 to restrict the cleaning water mist, forming a wall of cleaning water mist between the first guide hood 34 and the second guide hood 42, thereby increasing the contact area with the exhaust gas. It also eliminates the need for too many related devices, ultimately reducing installation costs and greatly improving cleaning efficiency.

[0048] like Figure 1 and Figure 7 As shown in the figure, an embodiment of the present invention proposes a shampoo production exhaust gas treatment device, including a washing component 2, which is disposed outside the spray device 1, and is used to treat the exhaust gas generated during the shampoo production process.

[0049] The washing assembly 2 includes a washing tower 21, an exhaust port 22, a filter layer 23, a condenser pipe 24, a vortex device 25, a drain pipe 26, an air inlet 27, and an air outlet 28.

[0050] In this embodiment of the invention, the spray device 1 is fixedly installed inside the washing tower 21, and a vortex device 25 is provided at the lower part of the spray device 1. The vortex device 25 is also installed inside the washing tower 21, and an air inlet 27 is provided at the lower part of the vortex device 25. The outside of the air inlet 27 is connected to the exhaust gas generated during the shampoo production process. Therefore, the exhaust gas enters the vortex device 25 from the air inlet 27. Multiple sets of air outlet strips 28 are provided around the bottom of the vortex device 25. The vortex device 25 can rotate the exhaust gas and disperse the exhaust gas from the air outlet strips 28. Due to the action of the vortex device 25, the exhaust gas entering the spray device 1 can rotate, which not only increases the time that the exhaust gas exists in the washing tower 21, but also increases the contact time with the cleaning water mist multiple times due to the rotation of the exhaust gas. Therefore, the vortex device 25 can improve the efficiency of the exhaust gas reaction.

[0051] A condenser pipe 24 is installed at the top of the spray device 1. The condenser pipe 24 contains liquid for condensation. When the waste gas is treated by the spray device 1, it will form large molecules. These molecules will condense into liquid as they pass through the condenser pipe 24. Drain pipes 26 are provided on both sides of the bottom of the scrubbing tower 21. The liquid produced by condensation will eventually be discharged from the drain pipes 26. A filter layer 23 is provided at the top of the condenser pipe 24. The waste gas after condensation treatment may still contain a small amount of toxic substances. These toxic substances will be adhered to the filter layer 23 after being screened. Finally, the treated waste gas will be discharged from the exhaust port 22 at the top of the scrubbing tower 21. This process is repeated.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0053] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
