[0002] During wastewater treatment, the bacterial culture tank, membrane tank, and flotation device generate exhaust gases containing various pollutants. For example, the exhaust gas from the bacterial culture tank may contain malodorous gases such as hydrogen sulfide and ammonia, as well as some volatile organic compounds (VOCs); the exhaust gas from the membrane tank may also contain small amounts of organic solvents and odorous substances produced by microbial metabolism; and the exhaust gas from the flotation device may contain harmful gases volatilized from the wastewater. If these gases are directly emitted into the atmosphere, they will cause air pollution and affect the air quality of the surrounding environment.

[0003] In recent years, with the continuous advancement of environmental protection technologies, a variety of efficient and economical exhaust gas treatment technologies and equipment have emerged, such as adsorption, absorption, combustion, and biological methods. These technologies provide technical support for the recovery and treatment of exhaust gas from bacterial tanks, membrane tanks, and flotation devices within wastewater treatment systems, making effective treatment and compliance with emission standards possible.

However, existing technologies typically involve fixed installation of spray nozzles, which limits the contact area between the spray liquid and the exhaust gas, resulting in a relatively limited purification effect.

[0005] Therefore, we urgently need to provide a purification tower for treating wastewater and waste gas. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Due to the limitations of existing technologies that typically use fixed-installation spray nozzles for spraying treatment, resulting in a limited contact area between the spray liquid and the exhaust gas and thus a relatively limited purification effect, please refer to... Figures 1-3 The embodiment provides a purification tower for treating wastewater and exhaust gas, which can effectively increase the contact area between the purification liquid and the exhaust gas, thereby improving the purification effect of the exhaust gas. The purification tower for treating wastewater and exhaust gas includes a base 1, a purification device is installed on the top of the base 1, and guide devices are installed on the left and right sides of the outer surface of the purification device. A combustion device is connected to the right side of the guide device.

[0028] The purification device includes a spray structure and an auxiliary structure, with the auxiliary structure installed at the top and middle of the spray structure. The spray structure includes a tower body 101, with an asynchronous motor 102 mounted at the top. A transmission component 103 is connected to the output end of the asynchronous motor 102. A rotating tube 104 is mounted in the middle of the transmission component 103, and a spray head 105 is connected to the bottom end of the rotating tube 104. The auxiliary structure includes a lower bearing 106, with an upper bearing 107 mounted at the top. An inlet pipe 108 is mounted on the outer surface of the upper bearing 107. A filter plate 109 is located at the bottom of the lower bearing 106, and an adsorption plate 110 is mounted at the top of the filter plate 109.

[0029] The rotating tube 104 is connected to the middle of the top surface of the tower body 101 via the lower bearing 106. The upper bearing 107 is connected to the top of the outer surface of the rotating tube 104. Both the lower bearing 106 and the upper bearing 107 are sealed bearings. The bottom of the tower body 101 is fixedly connected to the middle of the top surface of the base 1. The outer surfaces of the filter plate 109 and the adsorption plate 110 are connected to the inside of the tower body 101.

[0030] By setting up the purification device, the asynchronous motor 102 drives the transmission component 103 to drive the rotating tube 104, thereby driving the spray head 105 to rotate and spray, thus effectively increasing the contact area between the purified liquid and the exhaust gas.

[0031] When the purified liquid is sprayed, it is delivered into the rotating tube 104 through the inlet pipe 108. The asynchronous motor 102 is started to drive the transmission component 103. The output end of the asynchronous motor 102 drives the worm to rotate. The outer surface of the worm meshes with the outer surface of the worm wheel, thereby driving the rotating tube 104 to rotate. When the rotating tube 104 rotates, it drives the spray head 105 to rotate, thereby spraying the purified liquid with the spray head 105, which increases the contact area between the purified liquid and the waste gas. When the waste gas is treated by the purified liquid, the filter plate 109 filters and intercepts the particles in the waste gas, and the adsorption plate 110 adsorbs and collects the impurities in the waste gas. The filter plate 109 has a solid frame and multiple layers of filter screens are installed inside. The adsorption plate 110 has a solid frame and multiple layers of filter screens are installed inside. The multiple layers of filter screens are filled with adsorbent fillers such as activated carbon. Rectangular filler strips are provided on the surface of the adsorption plate 110 and the filter plate 109, thereby increasing the adsorption treatment area of ​​the waste gas.

[0032] Example 2:

[0033] Based on Implementation 1, existing technologies still have the problem that droplets of purified liquid in the exhaust gas can affect subsequent exhaust gas treatment. Please refer to... Figures 4-5This embodiment provides a purification tower for treating wastewater exhaust gas, which can effectively solve the problem of liquid droplets mixed in the exhaust gas affecting the subsequent treatment effect of the exhaust gas. The purification tower for treating wastewater exhaust gas includes a guiding device comprising an inlet pipe 201, a guiding pipe 202 installed on the top right side of the inlet pipe 201, a guide plate 203 installed inside the guiding pipe 202, and a guide pipe 204 installed in the middle of the bottom end of the guiding pipe 202. A one-way valve 205 is installed in the middle of the guide pipe 204. The inlet pipe 201 is fixedly installed on the bottom left side of the outer surface of the tower body 101. The top end of the guiding pipe 202 is connected to a rectangular hole opened near the top end on the middle right side of the tower body 101. The guide plate 203 is fixedly installed inside the guiding pipe 202 near the top end.

[0034] The combustion device includes a blower 301, the output end of which is connected to a combustion chamber 302. An exhaust pipe 303 is installed on the top surface of the combustion chamber 302 near the right end, and an abutment pipe 304 is installed on the top surface of the combustion chamber 302. The output end of the blower 301 is connected to the right side of the guide pipe 202 near the bottom, and the outer surface of the abutment pipe 304 abuts against the top surface of the combustion chamber 302 near the left end.

[0035] By setting up the guiding device and the combustion device, the guide plate 203 is used to separate and collect the liquid droplets in the exhaust gas to prevent the treatment liquid from affecting the exhaust gas treatment. Then, the heat energy of the exhaust gas combustion in the combustion chamber 302 is recovered by the connecting pipe 304.

[0036] The exhaust gas enters the tower body 101 through the inlet pipe 201. After being treated by the spray purification device, the exhaust gas is guided through the guide pipe 202. At the same time, the liquid droplets in the exhaust gas are guided by the guide plate 203. The liquid is collected through the guide pipe 204. Then, the exhaust gas is drawn into the combustion chamber 302 by the blower 301, where it is burned. During the combustion process, the flowing liquid inside the contact pipe 304 is heated, thereby recovering and utilizing the heat energy of the combustion and reducing resource waste. The exhaust gas after combustion is discharged through the exhaust pipe 303.
