Description

Technical Field

[0001] This utility model relates to the field of purification tower technology, specifically a multi-stage purification tower for treating chemical waste gas. Background Technology

[0002] A purification tower for chemical waste gas treatment is an environmentally friendly device specifically designed to treat toxic and harmful waste gases generated during chemical production. During operation, the chemical waste gas enters from the bottom of the tower, and pollutants are removed through chemical reactions, physical adsorption, or absorption. The purified gas is discharged from the top of the tower, while the waste liquid is discharged from the bottom for further treatment. This equipment is widely used in the chemical and pharmaceutical industries, effectively reducing the pollution of the environment by waste gases.

[0003] In existing chemical waste gas treatment purification towers, traditional spray systems often employ unidirectional spraying, resulting in uneven distribution of absorbent water flow within the packing layer and the formation of blind spots in some areas. Simultaneously, the waste gas rises rapidly within the tower, allowing only brief contact with the falling absorbent. This limited contact area and insufficient reaction time prevent the pollutants in the waste gas from being fully absorbed or reacted. For chemical waste gases with high concentrations or complex compositions, the purification effect is significantly reduced. Therefore, we propose a multi-stage purification tower for chemical waste gas treatment. Utility Model Content

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-4 As shown, a multi-stage purification tower for treating chemical waste gas includes a tower body 1. A first water pump 3 is fixedly installed on the top of the tower body 1. A delivery pipe 4 is fixedly connected to the water inlet end of the first water pump 3. The drain end of the first water pump 3 is located in the inner cavity of the tower body 1. An air inlet pipe 11 is fixedly inserted into one side wall panel at the bottom of the tower body 1. The upper part of the tower body 1 is rectangular. A first guide plate 7, a second guide plate 8, and a third guide plate 9 are fixedly connected to the inner wall panel of the upper part of the tower body 1. The first guide plate 7, the second guide plate 8, and the third guide plate 9 are arranged in a cross pattern. The three side walls of the first guide plate 7, the second guide plate 8, and the third guide plate 9 are fixedly connected to the inner wall of the tower body 1. The side wall panels of the first guide plate 7, the second guide plate 8, and the third guide plate 9 away from the inner wall of the tower body 1 together form a gas channel. A lifting mechanism 5 is provided on one side wall panel of the tower body 1. A circulation mechanism 6 is provided on the side wall panel of the tower body 1 away from the air inlet pipe 11.

[0020] It should be noted that an exhaust vent is provided through the top of tower body 1.

[0021] In practice, a clean water source is connected to the external water supply through the delivery pipe 4. The first water pump 3 is started to pump clean water into the tower body 1. When the water level in the tower body 1 reaches 5-10cm above the air inlet pipe 11 (ensuring the initial contact purification of the gas after entering the tower body 1 through the air inlet pipe 11), the first water pump 3 is stopped and the circulation mechanism 6 is activated. By controlling the output power of the circulation mechanism 6, the flow rate of the clean water is controlled, so that the clean water flows to the bottom of the tower body 1 through the first guide plate 7, the second guide plate 8 and the third guide plate 9, forming three water curtains. By using the inlet pipe 11 to connect to an external chemical waste gas exhaust pipe, the waste gas enters the bottom of the tower body 1 through the inlet pipe 11. It first comes into contact with the clean water at the bottom of the tower body 1, and the clean water filters and purifies the waste gas. The preliminarily purified waste gas rises and is purified again through three water curtains before being discharged through the exhaust port, thus enhancing the purification effect of the waste gas.

[0022] As a technical optimization of this utility model, the circulation mechanism 6 includes a second water pump 62 and a third water pump 63 fixedly installed on the side wall of the tower body 1. The inlet ends of the second water pump 62 and the third water pump 63 are respectively fixedly connected to a first insertion pipe 64 and a second insertion pipe 66. The outlet ends of the second water pump 62 and the third water pump 63 are respectively fixedly connected to a circulation pipe 61 and a drain pipe 65. The outer wall of the circulation pipe 61 is fixedly connected to the side wall of the tower body 1. The end of the circulation pipe 61 away from the second water pump 62 is fixedly inserted into the top of the inner cavity of the tower body 1. A second filter plate 10 is also fixedly connected to the bottom surface of the inner cavity of the tower body 1. The second filter plate 10 is used to divide the space at the bottom of the inner cavity of the tower body 1.

[0023] In practice, the wastewater at the bottom of the tower body 1 is filtered by the second filter plate 10, and the filtered water is pumped out by the second water pump 62 and transported to the top of the tower body 1 for filtration and recycling, thereby reducing the use of water resources.

[0024] As a technical optimization of this utility model, the lifting mechanism 5 includes a first filter plate 51 that is movably attached to the bottom of the inner cavity of the tower body 1. One side wall of the first filter plate 51 is slidably attached to the wall of the second filter plate 10. A connecting rod 52 is fixedly connected to the top surface of the first filter plate 51. The surface of the connecting rod 52 is slidably inserted into the wall of the tower body 1. An installation plate 54 is also fixedly connected to the side wall of the tower body 1. An electric telescopic rod 53 is fixedly installed on the bottom surface of the installation plate 54. The telescopic end of the electric telescopic rod 53 is fixedly connected to the top end of the connecting rod 52. A sealing door 2 is rotatably installed on one side wall at the bottom of the tower body 1. After the sealing door 2 is rotated to a specified angle, it is used to clean the bottom of the tower body 1.

[0025] It should be noted that the edge of the first filter plate 51 is in contact with the inner wall of the tower body 1.

[0026] In practice, the electric telescopic rod 53 is activated, and the connecting rod 52 is raised through the telescopic end of the electric telescopic rod 53. The rise of the connecting rod 52 causes the first filter plate 51 to rise, thereby causing the impurities on the bottom surface of the inner cavity of the tower body 1 to rise and be collected on the top surface of the first filter plate 51. The third water pump 63 is activated, and the sewage at the bottom of the tower body 1 is pumped out and discharged through the drain pipe 65. The sealing door 2 is opened to facilitate cleaning of the bottom inner cavity of the tower body 1.

[0027] In use, this invention connects to an external clean water source via the delivery pipe 4, and starts the first water pump 3 to draw clean water. The clean water flows through the first guide plate 7, the second guide plate 8, and the third guide plate 9 to the bottom of the tower body 1, forming three water curtains. An external chemical waste gas exhaust pipe is connected via the air inlet pipe 11, and the waste gas enters the bottom of the tower body 1 through the air inlet pipe 11. It first contacts the clean water at the bottom of the tower body 1, where the clean water filters and purifies the waste gas. The initially purified waste gas rises, passes through the three water curtains for further purification, and is discharged through the exhaust port. During the purification process, the second water pump 62 is started, and... The second water pump 62 draws the filtered water and transports it to the top of the tower body 1 for filtration and recycling. After the exhaust gas purification is completed, the electric telescopic rod 53 is activated. The telescopic end of the electric telescopic rod 53 drives the connecting rod 52 to rise. The rising connecting rod 52 drives the first filter plate 51 to rise, thereby causing the impurities on the bottom surface of the inner cavity of the tower body 1 to rise and be collected on the top surface of the first filter plate 51. The third water pump 63 is activated to draw the sewage from the bottom of the tower body 1 and discharge it through the drain pipe 65. The sealing door 2 is opened to clean the bottom inner cavity of the tower body 1.
