Description

Technical Field

[0001] This utility model relates to the field of absorption tower technology, specifically a spray-type absorption tower. Background Technology

[0002] Packed absorption towers are mainly used for gas-liquid mass transfer and the treatment of harmful gases. Their core function is to increase mass transfer efficiency by increasing the contact area, thereby achieving gas purification and resource recovery. They are widely used in chemical, environmental protection, petroleum, and power industries, and are core equipment for industrial gas treatment. One publicly available patent describes a circulating industrial waste gas spray absorption tower (Publication No.: CN 220495962 U), in which the residence time of waste gas inside the main body of the spray absorption tower is increased through the cooperation of spiral auxiliary components. After connecting the outer end of the water pipe to a water storage tank, the water supply to the spray frame is achieved through the water pipe. The sprayed water is filtered by the adsorption layer to remove impurities, and the filtered water enters the water pipe through the drain pipe, thus achieving water recycling. However, some drawbacks exist in use. Over time, impurities accumulate inside the adsorption layer, causing blockages and affecting the filtration effect. Manual cleaning is necessary, which is inconvenient and increases the burden on workers, affecting the normal operation of the absorption tower. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only some embodiments, not all embodiments. Based on the embodiments described, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0021] Example 1:

[0022] Please see Figure 1-3 A spray-type absorption tower includes a support base 1, an absorption tower 2 fixedly installed on the upper part of the support base 1, an air inlet pipe 3 installed on the lower front of the absorption tower 2, a spray pipe 4 installed inside the absorption tower 2, a filter frame 5 installed at the bottom inside the absorption tower 2, an adsorption layer 6 installed inside the filter frame 5, a motor 7 fixedly installed on the lower part of the support base 1, a rotating rod 8 rotatably installed on the bottom of the absorption tower 2, a rotating cylinder 9 fixedly installed on the upper end of the rotating rod 8, a spray pipe 10 fixedly installed on the outer side of the rotating cylinder 9, a movable sealing cap 11 rotatably installed on the upper part of the rotating cylinder 9, a connecting pipe 12 installed on the surface of the movable sealing cap 11, and an air outlet 17 provided on the upper part of the absorption tower 2.

[0023] Specifically, the waste gas enters the absorption tower 2 through the air inlet. The spray pipe 4 is connected to an external water pump through the liquid inlet pipe to draw in the absorption liquid. Then, the spray pipe 4 starts to spray the absorption liquid to treat the waste gas. The adsorption layer 6 in the filter frame 5 is made of quartz sand, which can remove larger suspended particles and other impurities in the waste liquid.

[0024] Preferably, a first water pump 18 is fixedly installed on the upper surface of the support base 1, and the outlet end of the first water pump 18 is connected to a first water pipe, and the first water pipe is sealed and connected to the outer end of the connecting pipe 12.

[0025] Specifically, the first water pump 18 can deliver water to the connecting pipe 12 through the first water pipe. The first water pump 18 is a high-pressure water pump that can generate high-pressure water flow for rinsing the adsorption layer 6.

[0026] Preferably, the output end of the motor 7 is fixedly connected to the lower end of the rotating rod 8, and the rotating rod 8 passes through the filter frame 5 and is rotatably connected to the surface of the filter frame 5.

[0027] Specifically, motor 7 can drive rotating rod 8 to rotate, and rotating rod 8 can then drive rotating cylinder 9 to rotate. Multiple layers of sealing rings are provided at the connection between rotating rod 8 and the bottom of absorption tower 2.

[0028] Working principle: After the waste gas enters, it is purified by spraying absorbent liquid through spray pipe 10. The sprayed liquid flows downward through adsorption layer 6, which filters some particulate impurities in the absorbent liquid. After preliminary filtration, the second water pump 19 draws away the absorbent liquid at the bottom through the second water pipe. The drawn-away absorbent liquid enters the next filtration device. After a long period of time, the first water pump 18 draws in cleaning water and then delivers it to the rotating drum 9 through connecting pipe 12. The movable sealing cap 11 does not rotate with the rotating drum 9. The rotation of the rotating drum 9 drives the spray pipe 10 to rotate, and the spray pipe 10 sprays high-pressure water to flush the adsorption layer 6, removing the impurities that clog the inside. This preliminary filtration of the liquid facilitates subsequent treatment, allows the liquid to be recycled, effectively prevents clogging, increases the service life of the adsorption layer 6, and reduces the workload of workers.

[0029] Example 2:

[0030] Please see Figure 1-3 A water outlet 13 is installed at the lower part of the spray pipe 4, and an installation rod 14 is fixedly installed at the lower part of the water outlet 13. A diffuser plate 15 is fixedly installed at the lower part of the installation rod 14.

[0031] Specifically, the diffuser 15 is located directly below the water outlet 13. Under the rapid impact of the water flow, it will spray outwards to increase the range of liquid spraying. There are multiple water outlets 13, which are evenly distributed in the lower part of the spray pipe 4.

[0032] Preferably, a guide plate 16 is installed inside the absorption tower 2, and the guide plate 16 is located at the lower part of the spray pipe 4.

[0033] Specifically, multiple guide vanes 16 are positioned below the spray pipe 4 and above the air inlet to guide, control, and adjust the direction, speed, and distribution of gas flow.

[0034] Preferably, a second water pump 19 is fixedly installed on the upper part of the support base 1, and a second water pipe is connected to the outside of the second water pump 19. The second water pipe is connected to the bottom of the absorption tower 2.

[0035] Working principle: When gas enters the absorption tower 2, it first passes through the guide plate 16. The guide plate 16 makes the gas distribution more uniform and disperses the high-speed or uneven airflow into a low-speed, uniform airflow. At the same time, when the liquid is sprayed downward through the outlet 13, it is blocked by the diffuser 15, so that the liquid can be sprayed over a wider area and avoids the formation of spray blind spots. This achieves full contact between liquid and gas, improves gas-liquid contact efficiency, and enhances the absorption effect of pollutants.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
