Description

Technical Field

[0001] This utility model relates to the field of environmental protection, and in particular to a liquid collection tank for exhaust gas from a screw vacuum pump. Background Technology

[0002] A screw vacuum pump, also known as a dry screw vacuum pump, is a pumping device that uses a pair of screws rotating synchronously at high speed in opposite directions within a pump casing to generate suction and exhaust. The two screws are finely dynamically balanced, supported by bearings, and installed in the pump casing. There is a certain clearance between the screws, so there is no friction during operation, resulting in smooth operation, low noise, and no need for lubrication of the working chamber. Therefore, dry screw pumps can pump gases containing large amounts of water vapor and small amounts of dust, achieving higher ultimate vacuums, lower power consumption, and offering advantages such as energy saving and maintenance-free operation. They are mainly used in high-purity vacuum processes, providing extremely high vacuum levels, adapting to harsh working conditions, and capable of pumping condensable gases and gases containing particulate matter. They are particularly suitable for clean environments and are easy to corrosion-resistant, making them especially suitable for fields such as electronics, chemicals, biopharmaceuticals, metal processing, and food processing.

[0003] Screw vacuum pumps are widely used in electronics, chemical, biopharmaceutical, metal processing, and food processing industries. However, these pumps emit exhaust gases during operation, requiring exhaust gas treatment systems to meet environmental regulations. Currently, the exhaust gases from existing screw vacuum pumps often contain large amounts of organic solvents. These solvents directly enter the downstream exhaust gas treatment system, resulting in a heavy treatment load, high treatment costs, and significant purification difficulties. The system is also prone to saturation and failure, increasing environmental costs for businesses. Utility Model Content

[0016] In this technical solution, the organic solvents in the exhaust gas of the screw vacuum pump can be adsorbed by the adsorption component, thereby improving the treatment effect of the organic solvents.

[0017] Preferably, the adsorption assembly includes multiple flat adsorption elements and multiple corrugated adsorption elements, which are distributed in a cross pattern, and both the flat adsorption elements and the corrugated adsorption elements are fixedly connected to the inner wall of the collection tank.

[0018] In this technical solution, the organic solvents in the exhaust gas are adsorbed using an adsorption component.

[0019] Preferably, the dispersing component includes a central box, the bottom of which is fixedly connected to the top of the anti-detachment rotating tube, and a plurality of dispersing cylinders are fixedly connected to the side of the central box.

[0020] In this technical solution, the exhaust gas discharged from the screw vacuum pump can be evenly dispersed below the adsorption component through the dispersion component.

[0021] Preferably, the drive assembly includes a power source, which is installed on the inner wall of the bottom surface of the protective housing, and the top of the protective housing is fixedly connected to the bottom of the cooling tank.

[0022] The output end of the power source is fixedly connected to a main gear, and a secondary gear is meshed with the side of the main gear. The secondary gear is fixedly connected to the bottom of the anti-detachment rotating tube.

[0023] In this technical solution, the anti-detachment rotating tube and the dispersion component are rotated by the driving component.

[0024] Preferably, a second gas inlet pipe is installed on the side of the collection tank, and a second liquid discharge pipe is installed at the bottom of the anti-detachment rotating pipe.

[0025] In this technical solution, the exhaust gas discharged by the screw vacuum pump is introduced into the dispersion component through the second gas inlet pipe, and the liquid collected in the collection tank is discharged through the second liquid discharge pipe.

[0026] Preferably, a mixing component is installed on the surface of the anti-detachment rotating tube. The mixing component is disposed in the space between the collection tank and the cooling tank. The mixing component includes connecting columns, and a plurality of connecting columns arranged in a ring array are fixedly connected to the surface of the anti-detachment rotating tube.

This intercepts the organic solvent in the exhaust gas, effectively eliminating the organic solvent brought into the system by the screw vacuum pump. As a result, the amount of organic solvent entering the exhaust gas treatment system is greatly reduced or it is no longer allowed to enter the system, thus reducing the treatment pressure on the exhaust gas treatment system.

[0036] Furthermore, the adsorption component can be used to further adsorb organic solvents. By driving the anti-detachment rotating tube and the dispersion component to rotate, the dispersion component can evenly disperse the exhaust gas below the adsorption component, so that the exhaust gas can be evenly contacted with the low temperature and the adsorption component, improving the cooling and adsorption effect and efficiency of the organic solvent, and making it easier to retain the organic solvent in the exhaust gas.

[0037] In addition, the anti-detachment rotating tube can simultaneously drive the mixing component to stir and mix the coolant, making the temperature of the coolant in each part uniform and improving the cooling effect of the coolant on the organic solvent in the collection tank.

[0055] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0056] Figures 1 to 8 The above is a structural schematic diagram of an embodiment of the screw vacuum pump exhaust gas accumulator tank of this utility model.

[0057] Example 1

[0058] like Figures 1 to 2 The screw vacuum pump exhaust liquid collection tank includes a collection tank 1 and a cover plate 2. The cover plate 2 is detachably installed on the top of the collection tank 1 by multiple sets of disassembly and assembly bolts 3. A cooling tank 4 is fixedly connected to the outside of the collection tank 1.

[0059] A gas inlet pipe 5 is fixedly connected to the side of the collection tank 1, and a gas outlet pipe 6 is fixedly connected to the top of the cover plate 2.

[0060] A barrier plate 7 is fixedly connected to the bottom of the cover plate 2.

[0061] Specifically, the height of the bottom side of the baffle plate 7 is lower than the height of the gas inlet pipe 5, and the width of the baffle plate 7 is greater than the diameter of the gas inlet pipe 5. The baffle plate 7 blocks the gas inlet pipe 5 to prevent the exhaust gas from the screw vacuum pump from entering the collection tank 1 and being discharged directly from the gas outlet pipe 6 or the overflow pipe 9, thus affecting the collection of liquid.

[0062] Furthermore, a sealing groove is provided on the top surface of the collection tank 1, and a sealing ring is placed in the sealing groove to ensure the sealing between the collection tank 1 and the cover plate 2 after connection.

[0063] After the collection tank 1 and the cover plate 2 are connected, the collection tank 1 and the cover plate 2 squeeze the sealing ring to achieve a seal between the collection tank 1 and the cover plate 2.

[0064] In this technical solution, the exhaust gas discharged from the screw vacuum pump can be cooled by the collection tank 1 and cooling tank 4, so that the organic solvent is cooled into liquid, thereby intercepting the organic solvent in the exhaust gas. This can effectively eliminate the organic solvent brought into the system by the screw vacuum pump, so that the organic solvent entering the exhaust gas treatment system is greatly reduced or does not enter the exhaust gas treatment system, thus reducing the treatment pressure of the exhaust gas treatment system.

[0065] The side of the collection tank 1 is fixedly connected to a liquid discharge pipe 8 and an overflow pipe 9, with the overflow pipe 9 located above the liquid discharge pipe 8.

[0066] When a certain amount of liquid is collected in the collection tank 1, in order to prevent the liquid from entering the exhaust gas treatment system from the gas outlet pipe 6, the excess liquid is automatically discharged from the overflow pipe 9.

[0067] An overflow collection container can be connected to one end of the overflow pipe 9 to collect the liquid discharged from the overflow pipe 9.

[0068] In this technical solution, the liquid discharge pipe 8 is used to discharge the liquid collected in the collection tank 1.

[0069] The cooling tank body 4 is equipped with a coolant inlet pipe 10 and a coolant outlet pipe 11 on its side, with the coolant outlet pipe 11 positioned above the coolant inlet pipe 10.

[0070] In this technical solution, coolant is added to the space between the collection tank 1 and the cooling tank 4 through the coolant inlet pipe 10, and the coolant is discharged through the coolant outlet pipe 11.

[0071] In use, connect the gas inlet pipe 5 to the exhaust port of the screw vacuum pump, connect the gas outlet pipe 6 to the exhaust gas treatment system, and add coolant to the space between the collection tank 1 and the cooling tank 4 through the coolant inlet pipe 10. Then, the exhaust gas discharged by the screw vacuum pump is passed into the collection tank 1 through the gas inlet pipe 5. At this time, the baffle plate 7 prevents the gas from being discharged directly, allowing the gas to descend and be cooled, so that the organic solvent in the exhaust gas is cooled into liquid and collected in the collection tank 1. Then, the other gases are discharged from the gas outlet pipe 6 to the exhaust gas treatment system for further treatment.

[0072] Example 2

[0073] As one embodiment of this application, such as Figures 3 to 8 The difference between the above and Embodiment 1 is that an adsorption component 12 is installed inside the collection tank 1, and a dispersion component 13 is installed below the adsorption component 12. An anti-detachment rotating tube 14 is fixedly connected to the bottom of the dispersion component 13, and the anti-detachment rotating tube 14 is rotatably connected to the bottom surface of the collection tank 1 and the bottom surface of the cooling tank 4.

[0074] The bottom end of the anti-detachment rotating tube 14 is fixedly connected to the output end of the drive assembly 15, which is installed at the bottom of the cooling tank 4.

[0075] In this technical solution, the adsorption component 12 can adsorb organic solvents in the exhaust gas of the screw vacuum pump, thereby improving the treatment effect of organic solvents.

[0076] The adsorption assembly 12 includes multiple flat adsorption elements 121 and multiple corrugated adsorption elements 122, which are distributed in a cross pattern. Both the flat adsorption elements 121 and the corrugated adsorption elements 122 are fixedly connected to the inner wall of the collection tank 1.

[0077] Specifically, multiple flat plate adsorption elements 121 and multiple wavy adsorption elements 122 are distributed from top to bottom.

[0078] The cross-section of the wave-shaped adsorption component 122 is a wave-shaped structure.

[0079] Both the flat plate adsorbent 121 and the corrugated adsorbent 122 are porous solid structures, and the materials are one or more of activated carbon, carbon molecular sieve, graphitized carbon black, organic polymer, molecular sieve, etc.

[0080] In this technical solution, the organic solvent in the exhaust gas is adsorbed by the adsorption component 12.

[0081] In use, the organic solvents in the exhaust gas are adsorbed by the flat plate adsorption element 121 and the corrugated adsorption element 122, thereby improving the effect of retaining organic solvents in the exhaust gas.

[0082] Furthermore, the wavy adsorption element 122 can increase the contact area with the exhaust gas, further improving the adsorption efficiency of organic solvents.

[0083] The dispersion component 13 includes a central box 131, the bottom of which is fixedly connected to the top of the anti-detachment rotating tube 14, and multiple dispersion cylinders 132 are fixedly connected to the side of the central box 131.

[0084] Specifically, the top of the dispersion cylinder 132 has multiple vents.

[0085] In this technical solution, the exhaust gas discharged from the screw vacuum pump can be evenly dispersed below the adsorption component 12 by the dispersion component 13.

[0086] The drive assembly 15 includes a power source 151, which is installed on the inner wall of the bottom surface of the protective housing 152. The top of the protective housing 152 is fixedly connected to the bottom of the cooling tank 4.

[0087] The output end of the power source 151 is fixedly connected to the main gear 153, and the main gear 153 is meshed with the auxiliary gear 154 on its side. The auxiliary gear 154 is fixedly connected to the bottom of the anti-detachment rotating tube 14.

[0088] In this technical solution, the anti-detachment rotating tube 14 and the dispersion component 13 are driven to rotate by the driving component 15.

[0089] A gas inlet pipe 2 16 is installed on the side of the collection tank 1, and a liquid discharge pipe 2 17 is installed at the bottom of the anti-detachment rotating pipe 14.

[0090] Specifically, the surface of the gas inlet pipe 16 is fixedly connected to the flat plate adsorption component 121, the corrugated adsorption component 122, and the side of the collection tank 1, and the bottom end of the gas inlet pipe 16 is rotatably connected to the top surface of the central box 131.

[0091] The anti-detachment rotating tube 14 has multiple connecting holes arranged in a ring array at the position of the inner cavity of the collection tank 1.

[0092] One end of the liquid discharge pipe 17 is rotatably connected to the bottom surface of the auxiliary gear 154 and the anti-detachment rotating pipe 14, and the other end of the liquid discharge pipe 17 is fixedly connected to the side of the protective shell 152.

[0093] In this technical solution, the exhaust gas discharged by the screw vacuum pump is passed through the dispersion component 13 via the gas inlet pipe 2 16, and the liquid collected in the collection tank 1 is discharged through the liquid discharge pipe 2 17.

[0094] One end of the gas inlet pipe 216 is connected to the exhaust port of the screw vacuum pump.

[0095] The liquid collected in the collection tank 1 enters the anti-detachment rotating tube 14 through the connecting hole, and then is discharged through the liquid discharge tube 17.

[0096] When in use, the power source 151 drives the main gear 153 to rotate, which in turn drives the secondary gear 154 to rotate. At this time, the anti-detachment rotating tube 14 rotates. When the anti-detachment rotating tube 14 rotates, it drives the central box 131 to rotate, which in turn drives the dispersion cylinder 132 to rotate. When the dispersion cylinder 132 rotates, it evenly discharges the exhaust gas to the area below the adsorption component 12.

[0097] At this time, under the action of the cooling tank 4, the organic solvent in the exhaust gas is cooled into liquid, and then the gas passes through the wave-shaped adsorbent 122 and the flat plate adsorbent 121 in sequence. The wave-shaped adsorbent 122 and the flat plate adsorbent 121 are used for re-adsorption to improve the treatment effect of organic solvent.

[0098] A mixing component 18 is installed on the surface of the anti-detachment rotating tube 14. The mixing component 18 is disposed in the space between the collection tank 1 and the cooling tank 4. The mixing component 18 includes a connecting column 181. A plurality of connecting columns 181 arranged in a ring array are fixedly connected to the surface of the anti-detachment rotating tube 14.

[0099] A central shaft 182 is fixedly connected to one end of the connecting column 181 away from the anti-detachment rotating tube 14, and a rotating sleeve 183 is rotatably connected to the surface of the central shaft 182.

[0100] Two rotating gears 184, distributed vertically, are fixedly connected to the surface of the rotating sleeve 183. The side of the rotating gear 184 meshes with the side of the ring gear 185. The ring gear 185 is fixedly connected to the outer surface of the collection tank 1.

[0101] Multiple stirring blades 186 arranged in a ring array are fixedly connected to the surface of the rotating sleeve 183.

[0102] Specifically, the stirring blade 186 is positioned between the two rotating gears 184.

[0103] In this technical solution, the coolant is mixed by the mixing component 18 to avoid uneven coolant temperature affecting the cooling effect of the organic solvent.

[0104] An anti-detachment slider 187 is fixedly connected to the top of the central shaft 182. The anti-detachment slider 187 is slidably connected to the inner wall of the annular track 188. The top of the annular track 188 is fixedly connected to the inner wall of the cooling tank 4.

[0105] In this technical solution, the rotation trajectory of structures such as the central shaft 182 is limited by the anti-detachment slider 187 and the annular track 188.

[0106] In use, the anti-detachment rotating tube 14 drives the connecting column 181 to rotate, which in turn drives the central shaft 182 to rotate, which in turn drives the rotating sleeve 183 and the rotating gear 184 to rotate. At this time, under the action of the ring gear 185, the rotating gear 184 rotates, which in turn drives the rotating sleeve 183 to rotate around the central shaft 182, which in turn drives the stirring blade 186 to rotate. The rotation of the central shaft 182 and the stirring blade 186 and other structures is used to stir and mix the coolant, so that the temperature of the coolant in each part is uniform.

[0107] When the central shaft 182 rotates, it drives the anti-detachment slider 187 to rotate within the annular track 188, thereby limiting the rotation trajectory of the central shaft 182 and other structures, making the rotation of the central shaft 182 and other structures more stable.

[0108] The bottom of the cooling tank 4 is fixedly connected with multiple support feet arranged in a ring array.

[0109] The power source 151 is a motor or other equipment that can output rotational kinetic energy.
