Some devices only adopt a single treatment method, such as simple spray treatment, mostly vertical single channels, there are dead angles in spraying, and the removal effect of complex components in organic waste gas is not good, it is difficult to meet strict environmental protection emission standards. For some devices with multi-stage treatment functions, there is a lack of effective coordination between each treatment link, resulting in low treatment efficiency and high operating costs.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0018] Embodiment: The present invention provides an industrial organic waste gas high-efficiency treatment device. Please refer to Figures 1 - 13 , which includes a heat exchange shell base 1 and a spray tank 2 arranged on the top of the heat exchange shell base 1. A discharge pipe 21 is arranged on the top of the spray tank 2. The device preliminarily precipitates and adjusts the temperature of the waste gas through the heat exchange shell base 1, and then conveys the waste gas to the spray tank 2 for multi-stage spraying and purification treatment, and finally realizes the up-to-standard discharge of the waste gas; Specifically, please refer to Figures 2 - 7 , a pre-spray mechanism 6 is arranged in the spray tank 2. The pre-spray mechanism 6 includes an inner tube body 61 and an outer tube body 64. A spiral blade 62 is fixed between the inner tube body 61 and the outer tube body 64. The spiral blade 62 divides the space between the inner tube body 61 and the outer tube body 64 into a spiral chamber 602. Through the design of the spiral chamber 602, the waste gas spirally rises therein, prolonging the contact time between the waste gas and the spraying liquid and improving the treatment effect of spraying and dissolution. An atomizing spray mechanism 7 is arranged in the inner tube body 61. The atomizing spray mechanism 7 includes a shaft tube 71 rotatably connected in the inner tube body 61. A pressurization chamber 712 is arranged in the shaft tube 71. An atomization chamber 611 is arranged between the shaft tube 71 and the inner tube body 61.

[0019] The input end of the spiral bin 602 is connected to the output end of the heat exchange seat 1 and is provided with a lower electromagnetic valve 603. The output end of the spiral bin 602 is connected to the input end of the atomization bin 611 and is provided with an upper electromagnetic valve 601. By controlling the opening and closing of the lower electromagnetic valve 603 and the upper electromagnetic valve 601, the orderly flow of waste gas in different treatment stages is realized; The output end of the atomization bin 611 is connected to the output end of the pressurization bin 712 and is provided with an inclined communication port 711. The output end of the pressurization bin 712 is connected with a plurality of horizontally arranged horizontal pipes 75. The output end of the pressurization bin 712 is also provided with a pressure valve 76. The air inlet direction of the inclined communication port 711 is tangentially arranged with the inner wall of the shaft tube 71, so that the waste gas forms a swirling flow after entering the pressurization bin 712, enhancing the mixing effect of the waste gas and the spraying liquid.

[0020] The top of the spraying tank 2 is provided with a final spraying mechanism 4 for final purification treatment of the waste gas after preliminary treatment. A discharge pipe 63 is arranged inside the spiral blade 62. A plurality of atomizing nozzles one 621 connected to the output end of the discharge pipe 63 are fixed at the bottom of the spiral blade 62. The top of the pre-spraying mechanism 6 is provided with a waste water recovery mechanism 5. The waste water recovery mechanism 5 is used to convey the treated water sprayed by the final spraying mechanism 4 into the discharge pipe 63. Through the waste water recovery mechanism 5, the recycling of the treated water is realized, and the utilization rate of water resources is improved.

[0021] The waste water recovery mechanism 5 includes a waste water tank 51. A reciprocating cover plate 52 is arranged inside the waste water tank 51. A sleeve 74 is fixed at the top of the shaft tube 71. A reciprocating thread 741 is arranged on the outer wall of the sleeve 74. A nut seat 54 matching the reciprocating thread 741 is fixed in the middle of the reciprocating cover plate 52. A sealing rubber ring 53 is fixed on the circumferential outer side of the reciprocating cover plate 52. The sealing rubber ring 53 abuts against the inner wall of the waste water tank 51.

[0022] A plurality of limit sliding grooves 531 are equidistantly and evenly arranged on the circumferential outer side of the sealing rubber ring 53. A limit sliding rail 511 matching the limit sliding grooves 531 is arranged on the inner wall of the waste water tank 51. The inner diameter of the lower half of the waste water tank 51 is equal to the outer diameter of the sealing rubber ring 53. The inner diameter of the upper half of the waste water tank 51 is larger than the outer diameter of the sealing rubber ring 53. The top of the reciprocating cover plate 52 is conical. The bottom of the waste water tank 51 is connected to the input end of the discharge pipe 63. A one-way air inlet valve 512 is also arranged on one side of the bottom of the waste water tank 51. When the shaft tube 71 rotates, it drives the sleeve 74 to rotate, and the reciprocating cover plate 52 reciprocates up and down in the waste water tank 51 through screw transmission, realizing the recovery and conveyance of the treated water.

[0023] The pressure valve 76 includes a valve seat 761 connected to the top of the shaft tube 71. A valve plug 762 is slidably connected within the valve seat 761. A tension spring 763 is fixed between the valve plug 762 and the valve seat 761. A displacement sensor 7621 is further provided within the valve plug 762. When the displacement sensor 7621 moves upward to the maximum stroke, the upper electromagnetic valve 601 closes and the lower electromagnetic valve 603 opens. When the displacement sensor 7621 moves downward to the maximum stroke, the upper electromagnetic valve 601 opens and the lower electromagnetic valve 603 closes. Through the linkage of the displacement sensor 7621 and the electromagnetic valves, automatic regulation of the waste gas treatment process is achieved.

[0024] The outer wall of the shaft tube 71 is further fixed with a pressurizing vane 77. The pressurizing vane 77 is arranged within the atomization chamber 611. An atomizing nozzle II 771 is provided on the pressurizing vane 77. The pressurizing vane 77 rotates driven by the shaft tube 71. On the one hand, it pressurizes the waste gas, and on the other hand, it further atomizes the spraying liquid through the atomizing nozzle II 771 to improve the treatment effect. The inner walls of the spiral vane 62 and the shaft tube 71 are both coated with an anti-sticking coating to prevent pollutants from adhering to the wall surface and extend the service life of the equipment. The inner bottom of the shaft tube 71 is fixed with a recovery port 73, which can recycle some of the liquid.

[0025] The heat exchange housing 1 includes a sedimentation tank 14 and a waste gas inlet 11 connected to the sedimentation tank 14. The heat exchange housing 1 is separated into a serpentine chamber at the top of the sedimentation tank 14 by vertically staggered partitions. A heat exchange tube group 12 is provided within the serpentine chamber. The output end of the sedimentation tank 14 is connected and arranged with the input end of the serpentine chamber. A primary cooling chamber 201 is provided at the connection between the spraying tank 2 and the heat exchange housing 1. The primary cooling chamber 201 is connected and arranged with the spiral chamber 602 through the lower electromagnetic valve 603. The output end of the serpentine chamber is connected and arranged with the primary cooling chamber 201. The outer wall of the heat exchange housing 1 is further filled with a heat insulation layer 13. The waste gas enters the sedimentation tank 14 through the waste gas inlet 11. After large particle impurities precipitate, the waste gas enters the serpentine chamber for temperature adjustment. The heat insulation layer 13 reduces heat loss.

[0026] A steam generator 3 is further fixed within the primary cooling chamber 201. A crown gear 31 is fixed to the output shaft of the steam generator 3. A driven gear 72 meshing with the crown gear 31 is fixed to the bottom of the shaft tube 71. The steam generated by the steam generator 3 through heat exchange is transported through a pipeline into the steam generator 3 as a supplementary steam source for the steam generator 3. The steam generator 3 converts the steam energy generated by heat exchange into mechanical energy. Through the transmission of the crown gear 31 and the driven gear 72, it drives the shaft tube 71 to rotate, achieving effective utilization of energy.

[0027] During actual use, industrial organic waste gas enters the sedimentation tank 14 of the heat exchange housing 1 through the waste gas inlet 11. In the sedimentation tank 14, due to the reduced waste gas flow rate, large particle impurities and some solid particles settle down under the action of gravity, initially removing larger pollutants in the waste gas. The waste gas after preliminary sedimentation enters the serpentine chamber. The heat exchange tube group 12 in the serpentine chamber exchanges heat with an external cold source or heat source. If the waste gas temperature is too high, the coolant in the heat exchange tube group 12 absorbs the heat of the waste gas to lower the waste gas temperature; if the waste gas temperature is too low, the heating medium in the heat exchange tube group 12 heats the waste gas to adjust the waste gas temperature to a range suitable for subsequent treatment (30 - 50 °C). The heat insulation layer 13 on the outer wall of the heat exchange housing 1 uses a material with good heat insulation performance, reducing heat dissipation and ensuring the stability of the heat exchange effect.

[0028] The waste gas after temperature adjustment enters the primary cooling chamber 201 from the serpentine chamber. Since spraying operations are simultaneously carried out in the spiral chamber 602, the spraying water inside it is discharged to the primary cooling chamber 201 through the lower electromagnetic valve 603 to further cool the waste gas entering the primary cooling chamber 201. When the temperature decreases, the thermal motion of gas molecules slows down, the ability of gas molecules to escape from the liquid phase weakens, and the force of liquid molecules on gas molecules relatively increases, enabling more VOCs molecules to dissolve in the liquid, thereby effectively improving the waste gas treatment efficiency through cooling. At the same time, the spraying liquid in the cooling chamber 201 is connected to the sedimentation tank 14 to replenish the liquid in the sedimentation tank 14, and the liquid with a high saturation of dissolved waste gas in the sedimentation tank 14 is connected to wastewater treatment equipment through a pipeline for the final wastewater treatment step; Meanwhile, the cooled waste gas enters the spiral chamber 602 in the spraying tank 2 through the lower electromagnetic valve 603. In the spiral chamber 602, the waste gas rises along a spiral path, extending the contact time with the spraying liquid. Then it can enter the atomization chamber 611 through the upper electromagnetic valve 601. The atomization spraying mechanism 7 in the atomization chamber 611 starts to work. The shaft tube 71 rotates under the drive of the steam generator 3, driving the pressurizing blade 77 to rotate. The atomizing nozzles II 771 on the pressurizing blade 77 fully atomize the spraying liquid and spray it into the waste gas to achieve preliminary mixing and purification. The spraying liquid in the atomizing nozzles II 771 can be water or a solution added with specific agents such as absorbents, catalysts, etc., which is selected according to the components of pollutants in the waste gas. The atomization effect of the atomizing nozzles II 771 and the rotating impact effect of the pressurizing blade 77 can make the spraying liquid form finer droplets, increasing the contact area between the droplets and solid particles, thereby improving the water melting efficiency of solid particles.

[0029] When the waste gas in the spiral chamber 602 rises to a certain level, the upper electromagnetic valve 601 opens, and the waste gas enters the atomization chamber 611 and enters the pressurization chamber 712 through the inclined communication port 711. Since the intake direction of the inclined communication port 711 is tangent to the inner wall of the shaft tube 71, the waste gas forms a rotating air flow in the pressurization chamber 712, enhancing the disturbance and mixing effect between the gas and the liquid, further improving the mixing effect with the spraying liquid. At the same time, in the pressurization chamber 712, the centrifugal force generated by the rotation of the shaft tube 71 and the central rotating air flow formed by the waste gas in the pressurization chamber 712 are utilized to produce a simple gas-liquid separation effect, separating the liquid droplets dissolved with the waste gas to the inner wall of the shaft tube 71, and falling for recovery by the recovery port 73.

[0030] At the same time, the pressurizing blade 77 can be used to pressurize the waste gas in the atomization chamber 611 and discharge it into the pressurization chamber 712. By pressurizing, the partial pressure of VOCs is increased, so as to promote more VOCs molecules to enter the liquid phase, thereby improving its dissolution rate. When the pressure in the pressurization chamber 712 reaches a certain value, the valve plug 762 of the pressure valve 76 moves upward under the action of pressure, overcoming the tension of the tension spring 763, and the pressure valve 76 opens. The waste gas and the atomized spraying liquid are discharged through the horizontal pipe 75 for further treatment.

[0031] The final spraying mechanism 4 at the top of the spraying tank 2 performs the final spraying treatment on the waste gas, further removing pollutants in the waste gas. Since the spraying liquid here only treats the waste gas that has been sprayed multiple times and the dissolution saturation of the treated water is low, it can be reused. The treated water falls into the surplus water tank 51 of the surplus water recovery mechanism 5. When the shaft tube 71 rotates, it drives the sleeve 74 to rotate, and through screw transmission, the reciprocating cover plate 52 moves up and down reciprocally in the surplus water tank 51. When the reciprocating cover plate 52 moves downward, the treated water in the surplus water tank 51 is squeezed into the discharge pipe 63 and sprayed into the spiral chamber 602 again through the atomizing nozzle 621 at the bottom of the spiral blade 62, realizing the recycling of the treated water. The one-way intake valve 512 on one side of the bottom of the surplus water tank 51 ensures that air can only enter unidirectionally, maintaining the air pressure balance in the surplus water tank 51 and preventing negative pressure from causing the water to be unable to be discharged normally.

[0032] The displacement sensor 7621 in the pressure valve 76 monitors the displacement of the valve plug 762 in real time. When the displacement sensor 7621 moves up to the maximum stroke, it indicates that the pressure in the pressurization chamber 712 is too high. At this time, the upper electromagnetic valve 601 closes and the lower electromagnetic valve 603 opens, stopping the intake of air into the pressurization chamber 712, and making the waste gas in the spiral chamber 602 carry out a new round of circulation to avoid damage to the equipment caused by excessive pressure; when the displacement sensor 7621 moves down to the maximum stroke, the upper electromagnetic valve 601 opens and the lower electromagnetic valve 603 closes, restoring the normal intake process to ensure the stable operation of the device.

[0033] The steam generator 3 in the primary cooling chamber 201 is driven by the steam generated through heat exchange. The steam enters the steam generator 3 through a pipeline, pushing the rotor of the generator to rotate, converting the thermal energy of the steam into electrical energy. The crown gear 31 on the output shaft of the steam generator 3 meshes with the driven gear 72 at the bottom of the shaft tube 71, transmitting mechanical energy to the shaft tube 71 and driving the shaft tube 71 to rotate, achieving effective utilization of energy and reducing the dependence on external power.

[0034] Through the design of the spiral chamber 602 of the pre-spray mechanism 6 in the present invention, the contact time between the waste gas and the spray liquid is extended during the spiral upward movement of the waste gas. Combined with the multiple atomizing sprays of the atomizing spray mechanism 7, a circuitous spray channel is formed without spray dead corners, realizing the full mixing of the waste gas and the spray liquid, greatly improving the removal efficiency of pollutants in the organic waste gas. At the same time, the residual water recovery mechanism 5 recycles the treated water of the final spray mechanism 4, further enhancing the treatment effect and reducing water resource consumption. The steam generator 3 is used to convert the steam energy generated by heat exchange into the rotational power of the shaft tube 71, reducing the input of external energy. At the same time, by pressurizing, the partial pressure of VOCs is increased, thus promoting more VOCs molecules to enter the liquid phase and further increasing its dissolution rate.

[0035] The linkage between the displacement sensor 7621 in the pressure valve 76 and the electromagnetic valve, as well as the automatic reciprocating movement of the reciprocating cover plate 52 in the residual water recovery mechanism 5, enable the device to automatically adjust the treatment parameters according to the actual situation of the waste gas, realizing intelligent operation, improving the operation stability and reliability, and reducing the labor cost and the risk of operation errors.

[0036] As described above, the above is only the best implementation mode adopted by the present application in combination with the current actual needs, but the protection scope of the present application is not limited thereto.
