Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection devices, in particular to a purification tower for environmental protection. Background Technique

[0002] With the development of society, environmental problems have increasingly become the focus of people's attention. Air quality is a major issue that people must face in their lives. The reason for the deterioration of air quality is that a large amount of waste gas generated by industrial production is discharged into the air. The purification of waste gas has become an essential device in industrial production. Currently, in industrial production, the purification tower has become the main device for purifying industrial waste gas.

[0003] A purification tower for environmental protection (publication number: CN208212878U) is disclosed in the prior art, which includes a tower body, a fan box, and an air outlet pipe. One end of the top of the base is provided with a tower body, and a liquid inlet pipe is installed on the tower body below the air inlet pipe. The output end of the liquid inlet pipe extends into the water tank provided at the bottom end inside the tower body. A packing layer is installed inside the tower body above the water tank, and a spraying device is installed inside the tower body above the packing layer. A water inlet pump is installed on the base on one side of the tower body, and a fan box is installed on the base on the side of the water inlet pump away from the tower body. One end of the top of the fan box is communicated with the top end of the tower body through an air supply pipe, and the other end of the top of the fan box is provided with an air outlet pipe.

[0004] However, the above technical solution and the prior art also have the following defects: During the use of this device, the waste gas directly enters the inside of the tower body through the air inlet pipe, and the waste gas is purified by the purification components above. However, since the waste gas directly enters the tower body through the air inlet pipe and the air inlet direction of the air inlet pipe is fixed, the waste gas is transported into the tower body in a directional manner along the direction of the air inlet pipe. The waste gas entering the tower body will accumulate on one side and flow along the upward air flow direction, unable to be evenly dispersed, resulting in uneven contact with the purification components and affecting the purification effect and efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide a purification tower for environmental protection to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A purification tower for environmental protection includes a tower body, an air inlet, a first air outlet, and a secondary purification device. The air inlet on one side of the bottom end of the tower body is connected to a dust removal mechanism through a diversion pipe. The first air outlet at the top end of the tower body is connected to the secondary purification device, and an entrainment separator layer, a spraying device, a packing layer, and a waste gas dispersion mechanism are sequentially arranged inside the tower body from top to bottom;

[0008] The waste gas dispersion mechanism is arranged inside the bottom end of the tower body near the air inlet, and is used to disperse the waste gas entering the tower body, so that the waste gas is evenly dispersed and purified inside the tower body, improving the purification efficiency.

[0009] Preferably, the waste gas dispersion mechanism includes a first servo motor, a rotating rod and a spiral plate. The first servo motor is arranged on the outer side of the bottom end of the tower body, and the output end of the first servo motor is fixedly connected with the rotating rod arranged inside the tower body through a coupling. The spiral plates are evenly distributed on the rotating rod.

[0010] Preferably, the waste gas dispersion mechanism further includes filter holes arranged on the spiral plates, further improving the uniform dispersion of the waste gas.

[0011] Preferably, the dust removal mechanism includes a cylinder body, a smoke inlet chamber, a water pump, a water suction pipe, a water outlet pipe and a reverse spray head. The water pump is arranged on the outer side of the cylinder body, and the water inlet end of the water pump is connected with the inner part of the bottom end of the cylinder body through the water suction pipe. The water outlet end of the water pump is fixedly connected with the reverse spray head arranged at the center of the inner part of the bottom end of the smoke inlet chamber through the water outlet pipe. The reverse spray head is used for the reverse spraying of the dust removal liquid to achieve the dust removal effect.

[0012] Preferably, the dust removal mechanism further includes a second air outlet arranged on the other side of the top end of the cylinder body. The second air outlet is connected with a diversion pipe, and a fan is arranged on the diversion pipe.

[0013] Preferably, a cooling plate and a stirring mechanism are arranged inside the bottom end of the cylinder body. The cooling plate is used for refrigerating the dust removal liquid inside the bottom end of the cylinder body, and the stirring mechanism is used for stirring the cooling liquid.

[0014] Preferably, the stirring mechanism includes a second servo motor and a stirring rod. The second servo motor is arranged on the outer side of the cylinder body, and the output end of the second servo motor is connected and fixed with the stirring rod arranged inside the cylinder body through a connecting shaft.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By arranging a waste gas dispersion mechanism inside the tower body near the air inlet, the waste gas entering the tower body through the air inlet can be actively dispersed evenly, increasing the contact area between the waste gas and the purification components inside the tower body, thereby improving the purification effect and reducing environmental pollution. The driving of the first servo motor drives the rotating rod and the spiral plate to rotate to the left, so that the waste gas is dispersed when the multiple spiral plates rotate and contact the waste gas. And during the process of the spiral plates contacting the waste gas, the waste gas can pass through the filter holes to be discharged, achieving more dispersed dispersion, thus increasing the contact area between the waste gas and the purification components and improving the purification effect;

[0017] 2. By setting up a dust removal mechanism, the waste gas before entering the tower body is dust-removed and cooled, thereby improving the purification efficiency and effect of the waste gas, enhancing environmental protection. The coolant inside the bottom end of the cylinder is sprayed out through the reverse spray head driven by a water pump. The reverse spray head sprays the coolant upward in the smoke inlet chamber. The upward-sprayed coolant can capture the dust particles of the waste gas in the smoke inlet chamber of the waste gas chamber. The adsorbed dust particles automatically fall due to the gravity of the coolant. Then, the dust-removed waste gas exits through the bottom end of the smoke inlet chamber, and the waste gas is cooled by using the contact between the coolant and the waste gas, effectively reducing the amount of dust entering the purification inside the tower body, which helps to improve the purification effect of the purification components inside the tower body on the waste gas, thereby further optimizing the purification effect.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] Embodiment 1:

[0026] A purification tower for environmental protection, comprising a tower body 1, an air inlet 2, a first air outlet 3 and a secondary purification device 5. The air inlet 2 on one side of the bottom end of the tower body 1 is connected to a dust removal mechanism 4 through a diversion pipe 10. The first air outlet 3 at the top end of the tower body 1 is connected to the secondary purification device 5. And inside the tower body 1, a demisting layer 7, a spraying device 8, a packing layer 6 and an exhaust gas dispersion mechanism 9 are sequentially arranged from top to bottom;

[0027] The exhaust gas dispersion mechanism 9 is arranged inside the bottom end of the tower body 1 near the air inlet 2, and is used for dispersing the exhaust gas entering the inside of the tower body 1, so that the exhaust gas is evenly dispersed and purified inside the tower body 1, and the purification efficiency is improved.

[0028] The exhaust gas dispersion mechanism 9 includes a first servo motor 901, a rotating rod 902 and a spiral plate 903. The first servo motor 901 is arranged on the outer side of the bottom end of the tower body 1, and the output end of the first servo motor 901 is fixedly connected to the rotating rod 902 arranged inside the tower body 1 through a coupling. The spiral plate 903 is evenly distributed on the rotating rod 902. The exhaust gas dispersion mechanism 9 further includes a filter hole 904 arranged on the spiral plate 903, which further improves the uniform dispersion of the exhaust gas.

[0029] In this embodiment, by arranging the exhaust gas dispersion mechanism 9 inside the tower body 1 near the air inlet 2, the exhaust gas entering the inside of the tower body 1 through the air inlet 2 is actively dispersed evenly, the contact area between the exhaust gas and the purification components inside the tower body 1 is increased, thereby improving the purification effect and reducing environmental pollution. The driving of the first servo motor 901 drives the rotating rod 902 and the spiral plate 903 to rotate to the left, so that the exhaust gas is dispersed when the plurality of spiral plates 903 rotate and contact the exhaust gas. And during the process of the spiral plate 903 contacting the exhaust gas, the exhaust gas can be more dispersedly dispersed through the filter hole 904, thereby increasing the contact area between the exhaust gas and the purification components and improving the purification effect.

[0030] Embodiment Two:

[0031] Based on Embodiment One, the dust removal mechanism 4 mentioned in Embodiment One is described:

[0032] The dust removal mechanism 4 includes a cylinder body 401, a smoke inlet chamber 402, a water pump 403, a water suction pipe 404, a water outlet pipe 405 and a reverse spray head 406. The water pump 403 is arranged on the outer side of the cylinder body 401, and the water inlet end of the water pump 403 is connected to the inside of the bottom end of the cylinder body 401 through the water suction pipe 404. The water outlet end of the water pump 403 is fixedly connected to the reverse spray head 406 arranged at the center of the inside of the bottom end of the smoke inlet chamber 402. The reverse spray head 406 is used for the reverse spraying of the dust removal liquid to achieve the dust removal effect.

[0033] The dust removal mechanism 4 further includes a second air outlet 407 provided on the other side of the top end of the cylinder body 401. The second air outlet 407 is connected to the diversion pipe 10, and a blower 11 is provided on the diversion pipe 10.

[0034] Inside the bottom end of the cylinder body 401, a cooling plate and a stirring mechanism 12 are provided. The cooling plate is used for refrigerating the dust removal liquid inside the bottom end of the cylinder body 401, and the stirring mechanism 12 is used for stirring the cooling liquid.

[0035] The stirring mechanism 12 includes a second servo motor 121 and a stirring rod 122. The second servo motor 121 is provided on the outside of the cylinder body 401, and the output end of the second servo motor 121 is fixedly connected to the stirring rod 122 provided inside the cylinder body 401 through a connecting shaft. By providing the stirring mechanism 12, the cooling liquid inside the bottom end of the cylinder body 401 and the cooling liquid that contacts the waste gas and absorbs the heat in the waste gas are stirred and mixed to ensure the uniform effect of the water temperature and improve the cooling effect.

[0036] In this embodiment, by connecting the air inlet 2 of the tower body 1 with the dust removal mechanism 4, the waste gas before entering the tower body 1 is dust-removed and cooled, thereby improving the purification efficiency and effect of the waste gas and enhancing environmental protection. The cooling liquid inside the bottom end of the cylinder body 401 is sprayed out through the reverse spray head 406 by the drive of the water pump 403. The cooling liquid is sprayed upward in the smoke inlet chamber 402 through the reverse spray head 406. The upward-sprayed cooling liquid can capture the dust particles of the waste gas in the smoke inlet chamber of the waste gas chamber. The adsorbed dust particles automatically fall due to the gravity of the cooling liquid. Then, the dust-removed waste gas exits through the bottom end of the smoke inlet chamber 402 and finally enters the inside of the tower body 1 through the second air outlet 407, achieving the dust removal effect, effectively reducing the amount of dust entering the purification inside the tower body 1, thereby improving the purification effect, and using the contact between the cooling liquid and the waste gas to cool the waste gas, which helps to improve the purification effect of the purification components inside the tower body 1 on the waste gas, thereby further optimizing the purification effect.

[0037] Working principle: During use, the waste gas enters the inside of the tower body 1 through the dust removal mechanism 4 for purification treatment. First, the waste gas enters the inside of the cylinder body 401 through the smoke chamber 402. When the smoke passes through the smoke inlet chamber 402, the dust removal and cooling treatment are achieved through the cooling liquid sprayed upward by the reverse spray head 406. The dust-removed and cooled waste gas enters the inside of the tower body 1 through the second air outlet 407 and the diversion pipe 10. When the waste gas enters the inside of the tower body 1 through the air inlet 2, the waste gas is dispersed by the waste gas dispersion mechanism 9, so that the waste gas uniformly passes through the packing layer 6, the spraying device 8 and the demisting layer 7, improving the purification effect and efficiency of the waste gas. The waste gas purified by the tower body 1 is further purified by the secondary purification device 5. When the purification reaches the standard, it is discharged through the exhaust port, improving the purification effect and thus enhancing environmental protection.

The scope of the present utility model is defined by the appended claims and their equivalents.
