Direct discharge will cause pollution to the environment, so it needs to be cleaned before discharge.

[0004] Currently, the most common method for purifying waste gas is aqueous solution absorption. During purification, the waste gas is passed through a corresponding aqueous solution so that the harmful substances therein are mixed with the aqueous solution to form precipitation or decompose, and then the treated gas is discharged. However, during the use of existing purification devices, it is difficult to fully mix the waste gas and the aqueous solution, resulting in unsatisfactory purification effect, and some harmful gases still exist in the discharged gas.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0040] like Figures 1 to 11 As shown, a waste gas purification device for a gas generator set of the present invention comprises: a purification box 1 for storing a treatment solution, a conveying mechanism 2 for conveying the waste gas into the purification box 1 , and a treatment mechanism 3 for purifying the waste gas in the purification box 1 .

[0041] The conveying mechanism 2 includes: a gas collecting cylinder 21 fixedly mounted on the purification box 1, an air inlet pipe 22 connected to the gas collecting cylinder 21, a piston 23 movably mounted in the gas collecting cylinder 21, a reset assembly 24 for driving the piston 23 to reset, an air guide pipe 25 connecting the gas collecting cylinder 21 and the movable shell 3111, and a gas outlet head 26 rotatably mounted on the movable shell 3111; the gas outlet head 26 is connected to the movable shell 3111, and a plurality of gas outlet heads 26 are arranged, which are evenly distributed in the movable shell 3111 in a ring shape. On, several air outlet heads 26 are immersed in the treatment solution, and several air outlet heads 26 are installed with a first one-way valve to prevent the treatment solution from flowing into the air outlet heads 26; the reset component 24 includes: a connecting rod 241 movably installed on the air collecting cylinder 21, the connecting rod 241 is fixedly connected to the piston 23 and drives a reset spring 242 for resetting the piston 23, one end of the reset spring 242 is fixedly connected to the piston 23, and the other end of the reset spring 242 is fixedly connected to the air collecting cylinder 21.

[0042] The exhaust gas is transported to the gas collecting cylinder 21 through the air intake pipe 22. As the exhaust gas is continuously transported to the gas collecting cylinder 21, the air pressure in the gas collecting cylinder 21 increases, which in turn drives the piston 23 to slide downward in the gas collecting cylinder 21. When the piston 23 moves to below the air intake end of the air guide pipe 25, the gas in the gas collecting cylinder 21 is quickly discharged through the air guide pipe 25, enters the movable shell 3111, and enters the treatment solution through the air outlet head 26. The exhaust gas can be purified by the treatment solution.

[0043] When the piston 23 slides downward in the gas collecting cylinder 21, it can drive the connecting rod 241 to move, and then drive the return spring 242 to compress. When the piston 23 moves to below the air inlet end of the air guide pipe 25, the gas in the gas collecting cylinder 21 is quickly discharged through the air guide pipe 25. At this time, the air pressure in the gas collecting cylinder 21 is reduced, and the elastic force of the return spring 242 can drive the piston 23 to reset upward, and the process is repeated.

[0044] By reciprocating the piston 23 up and down, the waste gas can be intermittently delivered to the treatment solution to ensure sufficient contact and reaction of the waste gas in the treatment solution, thereby improving the purification effect and avoiding the problem of insufficient treatment of the treatment solution due to excessive waste gas delivery.

[0045] The processing mechanism 3 includes: a purification component 31 for purifying the exhaust gas, and a filtering component 32 for filtering the purified gas.

[0046] The purification component 31 includes: an axial stirring unit 311 for axially stirring the treatment solution, a circumferential stirring unit 312 for circumferentially stirring the treatment solution, and an atomization unit 313 for auxiliary purification of the exhaust gas.

[0047] The axial stirring unit 311 includes: a movable shell 3111 movably installed in the purification box 1, the movable shell 3111 is provided with two movable rods 3114 fixedly installed on the movable shell 3111, a linkage 3112 driving the movable shell 3111 to move axially, and a guide member 3113 guiding the movable shell 3111 when moving axially; the guide member 3113 includes: a mounting frame 31131 rotatably installed with the movable rod 3114, a movable plate 31132 fixedly installed on the mounting frame 31131, and a connecting member 3112 driving the movable shell 3111 to move axially. A fixed plate 31133 installed in the purification box 1, and a limiting groove 31134 opened on the fixed plate 31133; the movable plate 31132 slides in the limiting groove 31134; the connecting member 3112 includes: a transmission gear 31123 rotatably installed on the fixed plate 31133, a horizontal rack 31121 and a vertical rack 31122 respectively meshing with the transmission gear 31123; the horizontal rack 31121 is fixedly connected to the mounting frame 31131, and the vertical rack 31122 is fixedly connected to the connecting rod 241.

[0048] As the piston 23 is acted upon by air pressure, it reciprocates up and down. When the piston 23 moves downward, it can drive the connecting rod 241 to move downward, thereby driving the vertical rack 31122 to move downward, the vertical rack 31122 drives the transmission gear 31123 to rotate, and the transmission gear 31123 drives the horizontal rack 31121 to move, thereby making the two movable shells 3111 approach each other; when the piston 23 is reset upward, it can drive the vertical rack 31122 to reset upward, the vertical rack 31122 drives the transmission gear 31123 to rotate in the opposite direction, and the transmission gear 31123 drives the horizontal rack 31121 to reset, thereby making the two movable shells 3111 move away from each other.

[0049] When the movable shell 3111 moves, it can drive the movable rod 3114 to move, the movable rod 3114 can drive the mounting frame 31131 to move, and the mounting frame 31131 can drive the movable plate 31132 to slide in the limiting groove 31134. Through the mutual cooperation between the movable plate 31132 and the limiting groove 31134, the mounting frame 31131 can be limited when moving, and then the movable shell 3111 can be limited when moving, so that the movable shell 3111 can achieve axial stirring of the treated solution.

[0050] In the present application, by moving the two movable shells 3111 closer to or farther away from each other, on the one hand, the treatment solution can be axially stirred, so that the exhaust gas can fully contact and react in the treatment solution, further improving the purification effect; on the other hand, the treatment solution can produce convection, thereby causing the treatment solution to continuously flow and penetrate each other, thereby improving the effect of axial stirring, further allowing the exhaust gas to fully contact and react in the treatment solution, and further improving the purification effect.

[0051] The circumferential stirring unit 312 includes: a fixed tube 3121 fixedly mounted on the purification box 1, a guide groove 3122 opened in the fixed tube 3121, the guide groove 3122 is spirally shaped, and a rolling member 3123 rotatably mounted on the movable rod 3114; the rolling member 3123 rolls in the guide groove 3122, and the movable rod 3114 is movably mounted in the fixed tube 3121.

[0052] When the movable rod 3114 moves, it can drive the rolling element 3123 to roll in the guide groove 3122. Since the guide groove 3122 is spiral, under the guidance of the path of the guide groove 3122, the movable rod 3114 can rotate along the circumference of the fixed tube 3121. The movable rod 3114 drives the movable shell 3111 to rotate along the circumference of the fixed tube 3121. The movable shell 3111 drives several air outlet heads 26 to rotate along the circumference of the fixed tube 3121, thereby realizing circumferential stirring of the treatment solution.

[0053] In the present application, a plurality of gas outlet heads 26 rotate along the circumference of the fixed tube 3121, which can, on the one hand, play a role of circumferential stirring on the treatment solution, so that the treatment solution forms a continuous circulation flow in the circumferential direction, so that the various components in the treatment solution can be more fully mixed, thereby improving the mixing uniformity, allowing the exhaust gas to fully contact and react in the treatment solution, and further improving the purification effect; on the other hand, it makes the exhaust gas have a wide distribution range in the treatment solution, thereby increasing the contact area between the exhaust gas and the treatment solution, further allowing the exhaust gas to fully contact and react in the treatment solution, and further improving the purification effect.

[0054] It is to be added here that the rolling element 3123 is preferably a bull's eye ball.

[0055] In the present application, the axial stirring unit 311 and the circumferential stirring unit 312 cooperate with each other to achieve axial and circumferential stirring of the treatment solution, and drive the exhaust gas to fully contact and react in the treatment solution, thereby further improving the purification effect. This solves the problem that it is difficult to fully mix the exhaust gas and the aqueous solution during the use of the existing purification device, resulting in unsatisfactory purification effect and the presence of some harmful gases in the exhausted gas.

[0056] A gear ring 27 is fixedly mounted on the mounting frame 31131, and a linkage gear 28 is fixedly sleeved on the air outlet head 26. The gear ring 27 and the linkage gear 28 are meshed with each other.

[0057] When the movable shell 3111 rotates along the circumference of the fixed tube 3121, the air outlet head 26 can be driven to rotate along the circumference of the fixed tube 3121, and the air outlet head 26 drives the interlocking gear 28 to rotate along the circumference of the fixed tube 3121. Since the gear ring 27 and the interlocking gear 28 are meshed with each other, the interlocking gear 28 rotates along the circumference of the fixed tube 3121 while rotating on its own, thereby driving the air outlet head 26 to rotate along the circumference of the fixed tube 3121 while rotating on its own.

[0058] By having the gas outlet head 26 rotate along the circumferential direction of the fixed tube 3121 while rotating on its own, on the one hand, the treatment solution can be further stirred circumferentially, so that the exhaust gas and the treatment solution are fully mixed, and the purification effect of the exhaust gas is further improved; on the other hand, the exhaust gas is distributed over a wide range in the treatment solution, thereby increasing the contact area between the exhaust gas and the treatment solution, further allowing the exhaust gas to fully contact and react in the treatment solution, and further improving the purification effect.

[0059] As a further extension of the present application, although the axial stirring unit 311 and the circumferential stirring unit 312 cooperate with each other to achieve axial and circumferential stirring of the treatment solution, allowing the exhaust gas to fully contact and react in the treatment solution, thereby improving the purification effect, the exhaust gas discharged from the outlet head 26 may form bubbles that are not broken by the axial stirring unit 311 and the circumferential stirring unit 312, causing the bubbles to float to the surface of the treatment solution and then burst, resulting in incomplete exhaust gas purification.

[0060] The present application can solve the above-mentioned problem by providing an atomizing unit 313, which includes: a capsule 3131 fixedly installed between the piston 23 and the gas collecting cylinder 21, a liquid inlet pipe 3132 connecting the capsule 3131 and the purification box 1, a second one-way valve installed on the liquid inlet pipe 3132, a liquid collecting shell 3133 connected to the capsule 3131, and an atomizing nozzle 3134 connected to the liquid collecting shell 3133, a third one-way valve installed on the atomizing nozzle 3134, and a plurality of atomizing nozzles 3134 are provided, which spray in different directions respectively, thereby expanding the atomization range and filling the purification box 1 with atomized treatment solution.

[0061] When the piston 23 moves downward, it can drive the capsule 3131 to be compressed. At this time, the second one-way valve is closed and the third one-way valve is opened, so that the treatment solution in the capsule 3131 can be squeezed into the liquid collecting shell 3133 and sprayed out through the atomizing nozzle 3134. Then, when the bubbles formed by the exhaust gas float to the liquid surface of the treatment solution and burst, the atomized treatment solution can purify the exhaust gas in this case. Since there are several atomizing nozzles 3134, which spray in different directions respectively, the atomization range is expanded, so that the purification box 1 is filled with atomized treatment solution, thereby achieving thorough purification of the exhaust gas and greatly improving the purification effect of the exhaust gas.

[0062] When the piston 23 is reset upward, the capsule 3131 itself has a certain elasticity, which can assist in resetting the piston 23. When the capsule 3131 is restored, the second one-way valve is opened and the third one-way valve is closed, so that the treatment solution in the purification box 1 can be absorbed into the capsule 3131 through the liquid inlet pipe 3132, thereby preparing for subsequent atomization.

[0063] In the present application, through the setting of the capsule 3131, on the one hand, the treatment solution can be transported to the liquid collecting shell 3133 and atomized and sprayed out through the atomizing nozzle 3134. Then, when the bubbles formed by the exhaust gas float to the liquid surface of the treatment solution and burst, the atomized treatment solution can purify the exhaust gas in this case, thereby achieving thorough purification of the exhaust gas and greatly improving the purification effect of the exhaust gas. On the other hand, when the piston 23 is reset upward, since the capsule 3131 itself has a certain elasticity, it can assist in resetting the piston 23.

[0064] The filter assembly 32 includes: an air outlet pipe 321 connected to the purification box 1 , a catalytic filter 322 fixedly installed in the air outlet pipe 321 , and an activated carbon filter 323 .

[0065] By setting up the catalytic filter 322 and the activated carbon filter 323, the gas purified by the treatment solution can be further degraded to remove harmful gases and remove odors and bacteria, thereby improving the purification effect of the exhaust gas. The filtered gas is discharged through the outlet pipe 321.

[0066] It also includes: a heat exchange mechanism 4 for utilizing the heat in the exhaust gas; the heat exchange mechanism 4 includes: a water tank 41, a water inlet pipe 42 connected to the water tank 41, and a water outlet pipe 43; the air inlet pipe 22 passes through the water tank 41, and the part of the air inlet pipe 22 located in the water tank 41 is spiral, which increases the contact area with water, thereby improving the heat exchange efficiency.

[0067] A certain amount of water is injected into the water tank 41 through the water inlet pipe 42. When the exhaust gas passes through the air inlet pipe 22, the water in the water tank 41 can be heated. When the water in the water tank 41 is heated to the required temperature, it can be discharged through the water outlet pipe 43 for use, and a certain amount of water is injected into the water tank 41 again for heating, thereby realizing the recovery and utilization of heat in the exhaust gas, avoiding heat loss and improving energy utilization.

[0068] It should be added here that heat-conducting fins can be installed on the spiral pipe section of the air intake pipe 22 to further improve the heat exchange efficiency, and a mixing device can be installed in the water tank 41 to stir and mix the water in the water tank 41 to make the heat of the water for heat exchange more uniform.

[0069] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.
