Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to a biological deodorization tower. Background Technique

[0002] The principle of the biological deodorization tower is as follows: the waste gas and odor first need to be pretreated. The pretreatment is to remove the particulate matter in the waste gas and odor, and to adjust the temperature and humidity of the waste gas and odor. Then, the treated gas enters the biological deodorization tower through a gas distributor. The biological deodorization tower is filled with biological fillers containing microorganisms and a certain amount of moisture.

[0003] For example, the patent document with the publication number of CN220125898U discloses a waste gas biological deodorization tower. The pretreatment component includes an air inlet pipe, a high-pressure gas chamber, a gas tray and a gas distribution pipe. A gas tray is arranged above the pre-washing pool, and the gas distribution pipe extends into the pretreatment water. The waste gas pipeline is connected to the air inlet pipe. As the waste gas increases, the pressure of the waste gas increases. The high-pressure waste gas enters the gas tray and is discharged through the gas distribution pipe, so as to divide the waste gas flow, make the waste gas uniformly contact with the pretreatment water, and make the fine particulate matter in the waste gas contact with the water, so as to improve the filtering effect on the fine particulate matter in the waste gas. However, since the gas density is much smaller than that of the liquid, the waste gas quickly floats away from the pretreatment liquid after entering the pretreatment liquid, resulting in a short treatment time and incomplete treatment.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0023] The present invention will be further described below in conjunction with the accompanying drawings:

[0024] As Figure 1 - Figure 4 shown, a biological deodorization tower includes an equipment platform 100. The upper surface of the equipment platform 100 is fixedly connected with a tank tower 200. A circulation mechanism is provided on one side of the tank tower 200. The circulation mechanism includes a pressure tank 301. The bottom end of the pressure tank 301 is fixedly connected to the equipment platform 100. A first circulation pipe 302 is inserted through the upper side of the pressure tank 301. The first circulation pipe 302 is inserted through the tank tower 200. A first check valve 304 leading from the tank tower 200 to the pressure tank 301 is connected in series in the middle of the first circulation pipe 302. A second circulation pipe 303 is inserted through the bottom of the pressure tank 301. A second check valve 305 leading from the pressure tank 301 to the tank tower 200 is connected in series in the middle of the second circulation pipe 303. A pressure-changing component is provided in the pressure tank 301. An aeration component is provided at the bottom of the tank tower 200. An air intake mechanism is provided in the middle of the tank tower 200. A stirring mechanism is provided outside the air intake mechanism.

[0025] After the waste gas enters the treatment liquid in the tank tower 200, after a short treatment, the waste gas quickly escapes to the upper part inside the tank tower 200. The pressure-changing component reduces the air pressure inside the pressure tank 301. The gas after the primary pretreatment enters the pressure tank 301 through the first circulation pipe 302. The first one-way valve 304 is used to maintain the one-way flow of the first circulation pipe 302. At this time, by controlling the pressure-changing component to increase the internal pressure of the pressure tank 301, the gas enters the pretreatment liquid at the bottom of the tank tower 200 through the second circulation pipe 303 to continue the reaction. The second one-way valve 305 is used to prevent the pretreatment liquid from entering the pressure tank 301. After circulating multiple times, a better deodorization treatment can be completed.

[0026] The pressure-changing component includes an electric telescopic rod 307. The top end of the electric telescopic rod 307 is fixedly connected to the pressure tank 301, and the bottom end of the electric telescopic rod 307 is fixedly connected with a piston 306. The piston 306 is hermetically and slidably connected to the pressure tank 301.

[0027] The electric telescopic rod 307 controls the piston 306 to slide up and down. When the piston 306 slides upward, the internal air pressure of the pressure tank 301 decreases. When the piston 306 moves downward, the internal air pressure of the pressure tank 301 increases.

[0028] The aeration component includes a gas-dispersing ring 308. The gas-dispersing ring 308 is inserted into the second circulation pipe 303, and a spray head 309 is arranged at the bottom of the gas-dispersing ring 308 in a circumferential array.

[0029] The gas-dispersing ring 308 is used to install the spray head 309, so that the gas-liquid contact area is larger when the gas enters the pretreatment liquid.

[0030] The air inlet mechanism includes an air inlet pipe 401. The air inlet pipe 401 is inserted through the top of the tank tower 200, and a gas-dispersing plate 402 is inserted at the bottom end of the air inlet pipe 401.

[0031] The air inlet pipe 401 is used to guide the external waste gas into the tank tower 200 and into the bottom of the pretreatment liquid. The gas-dispersing plate 402 is used for the impact contact of gas and liquid.

[0032] The stirring mechanism includes an internal gear ring 501. The internal gear ring 501 is rotatably connected to the middle part of the inner wall of the tank tower 200. The bottom surface of the internal gear ring 501 is fixedly connected with stirring plates 503 arranged in a circumferential array. The internal gear ring 501 meshes with a gear 502. The middle part of the top surface of the gear 502 is fixedly connected with a rotating shaft 505. The top of the rotating shaft 505 is rotatably connected to the tank tower 200. A motor 504 is installed at the top outside the tank tower 200, and the output shaft of the motor 504 is fixedly connected with the rotating shaft 505.

[0033] The motor 504 provides rotational power to drive the rotation of the rotating shaft 505. The rotating shaft 505 drives the rotation of the gear 502, the gear 502 drives the rotation of the internal gear ring 501, and the internal gear ring 501 drives the stirring plate 503 to stir the pretreatment liquid, making the filler in the pretreatment liquid more uniform and achieving a better effect when the gas and liquid interact.

[0034] An air outlet pipe 600 is inserted through the top surface of the tank tower 200.

[0035] The air outlet pipe 600 is used for discharging the gas after the treatment is completed.

[0036] Working principle:

[0037] The waste gas enters the tank tower 200 from the air inlet pipe 401, enters the pretreatment liquid through the air dispersing plate 402 and comes into full contact with the pretreatment liquid. As the waste gas escapes from the surface of the pretreatment liquid and enters the upper layer of the tank tower 200, start to retract the electric telescopic rod 307, the piston 306 rises, the internal air pressure of the pressure tank 301 decreases, and the waste gas that has not been completely treated enters the pressure tank 301 through the first circulation pipe 302 and the first one-way valve 304. Subsequently, extend the electric telescopic rod 307, the piston 306 descends, and the gas in the pressure tank 301 is squeezed and enters the bottom of the tank tower 200 through the second circulation pipe 303 and the second one-way valve 305, and comes into contact with the pretreatment liquid again. The gas passes through the air dispersing ring 308 and the nozzle 309 and comes into contact with the pretreatment liquid again. This process is repeated multiple times to make the deodorization treatment more thorough.

[0038] While the waste gas is in full contact with the pretreatment liquid, the motor 504 provides rotational power to drive the rotation of the rotating shaft 505. The rotating shaft 505 drives the rotation of the gear 502, the gear 502 drives the rotation of the internal gear ring 501, and the internal gear ring 501 drives the stirring plate 503 to stir the pretreatment liquid, making the filler in the pretreatment liquid more uniform.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
