Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a spray tower wastewater treatment device. Background Technology

[0002] Spray towers exist as a type of environmental waste gas treatment equipment. Based on their working principles, they are classified into circulating water spray towers, alkaline spray towers, and acid spray towers. The main function of spray towers is to treat waste gas by removing pollutants from the waste gas through spraying media. When dust-laden waste gas passes through a spray tower, the spraying media inside the tower comes into contact with the waste gas, and the pollutants are removed through neutralization reactions or water bath washing. Therefore, spray towers generate a certain amount of wastewater during operation. In order to make the water recyclable and reduce water consumption, it is necessary to equip spray towers with corresponding wastewater treatment devices.

[0003] The prior art discloses a waste gas treatment spray device with application number CN202321307659.2. In use, the wastewater generated after spraying can be pumped into a circulating water tank through a first water pump and a first water pipe for impurity filtration. The treated wastewater can then be recycled for spraying. However, wastewater containing impurities is prone to clogging and equipment failure when passing through the first water pump and the first water pipe. Moreover, after filtering the wastewater for a period of time, the filter screen in the circulating water tank needs to be manually disassembled by the user to remove the impurities clogging the filter screen. The operation is cumbersome and complicated, which not only increases the user's workload but also reduces the working efficiency of the equipment. Its practicality is relatively limited. In view of the shortcomings of this utility model, those skilled in the art have proposed a spray tower wastewater treatment device. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a spray tower wastewater treatment device, which has the following beneficial effects:

[0016] (1) This utility model is equipped with a spray tower body, a sewage treatment tank, and a filter screen. The spray tower body is fixedly installed on the mounting bracket, and a first rotating shaft is installed in the center of the spray tower body. The bottom end of the first rotating shaft is connected to the output end of a servo motor. A baffle plate is symmetrically fixedly installed on the first rotating shaft, and a scraper plate is fixedly installed on one side of the baffle plate. The scraper plate abuts against the inner wall of the spray tower body. In use, the waste gas to be treated is introduced into the inner cavity of the spray tower body through the air inlet pipe. Then, the servo motor is started to drive the first rotating shaft and the baffle plate to rotate and agitate the introduced waste gas. At the same time, the water is turned on. The valve directs the spray liquid through the inlet pipe into a connecting pipe installed inside the spray tower body. Finally, the liquid is sprayed onto the inner cavity of the spray tower body through several spray pipes and spray heads connected to the connecting pipe. The spray liquid washes and neutralizes impurities and harmful substances in the exhaust gas. A wastewater treatment tank is mounted on a mounting frame, with a second rotating shaft installed in the center of the tank. Several neutralizing and stirring rods are fixedly mounted on the second rotating shaft. Several mounting seats are fixedly mounted on the inner wall of the wastewater treatment tank, and mounting bushings are fixedly mounted inside the mounting frame, with the second rotating shaft fitted inside the mounting bushings. A filter screen is fixedly installed inside the outer circular frame. The frame can be mounted on the mounting base using mounting bolts and screw holes. A sewage pipe connects the bottom of the spray tower's inner cavity to the sewage treatment tank's inner cavity. Wastewater generated from the spray tower's waste gas treatment process is introduced into the sewage treatment tank through the sewage pipe and filtered by several filter screens. A first bevel gear is fixedly installed on a first rotating shaft, and a second bevel gear is fixedly installed on a second rotating shaft. The second bevel gear meshes with the first bevel gear, so rotating the first shaft drives rotating the second shaft. A brush holder is symmetrically fixedly installed on the second rotating shaft, and a cleaning brush is fixedly installed on one side of the brush holder. When the second rotating shaft drives the cleaning brush, it cleans the impurities clogging the filter screen. The cleaned dirt can then be discharged by opening the drain valve on the sludge discharge pipe. This allows the spray tower sewage treatment device to automatically clean the filter screen without adding an extra motor, eliminating the need for frequent manual disassembly and cleaning by the user. It is more convenient, efficient, and practical.

[0017] (2) This utility model is equipped with a neutralizing stirring rod, a liquid adding pipe and a circulating water pipe. As mentioned above, the sewage in the inner cavity of the sewage treatment tank can be filtered to remove impurities through multiple filter screens. The inner cavity of the sewage treatment tank is equipped with a pH sensor. The pH sensor can be used to detect the pH value of the sewage after filtration and impurity removal. According to the chemical properties of the treated waste gas, the user can add a certain amount of acid or alkali to the inner cavity of the sewage treatment tank through the liquid adding pipe to restore its function of washing waste gas. Then, the circulating water pump is started to pump the treated sewage back into the inlet pipe through the circulating water pipe and the three-way pipe. The sewage then enters the connecting pipe, spray pipe and spray head again through the inlet pipe for recycling, effectively reducing the water consumption of the spray tower and making it more practical.

A baffle plate 6 is symmetrically fixedly installed on the first rotating shaft 2, and a scraper 5 is fixedly installed on one side of the baffle plate 6, with the scraper 5 abutting against the inner wall of the spray tower body 3. In use, the waste gas to be treated is introduced into the inner cavity of the spray tower body 3 through the air inlet pipe 4. Then, the servo motor 9 is started to drive the first rotating shaft 2 and the baffle plate 6 to rotate and agitate the introduced waste gas. At the same time, the water valve 19 is opened to introduce the spray liquid into the connecting pipe 7 installed in the inner cavity of the spray tower body 3 through the water inlet pipe 21.
