Description

Technical Field

[0001] The utility model relates to a vertical annular spray scrubbing tower system, belonging to the technical field of scrubbing tower equipment. Background Art

[0002] A scrubbing tower, also known as a scrubber or a gas scrubber, is an industrial equipment for gas purification, which is widely used in chemical industry, environmental protection and other industrial fields to remove pollutants in gases. It mainly realizes the absorption and cleaning effects of harmful substances in the gas by contacting the cleaning liquid (such as water, alkali solution or other chemical solutions) in the tower with the gas.

[0003] In the current conventional scrubbing towers, the cleaning liquid sprayed by the nozzles is mainly distributed inside the tower body. Each nozzle cannot be manually intervened and controlled. When a failure occurs, the maintenance and inspection are more troublesome and the machine must be stopped for maintenance. Moreover, it is impossible to conveniently adjust the liquid output of each nozzle, which is not conducive to ensuring the uniformity of the sprayed cleaning liquid inside the tower body. Therefore, the actual efficiency of cleaning the gas is easily low. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a vertical annular spray scrubbing tower system for the uniform spraying operation of the scrubbing tower. After problems occur in the operation of individual nozzles, the nozzles can be adjusted and maintained without stopping the machine, which is beneficial to ensuring the normal operation of each nozzle during the operation of the equipment and avoiding the cumbersome nozzle adjustment steps caused by shutdown and the like.

[0005] To achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0006] A vertical annular spray scrubbing tower system provided by the utility model includes a tower body and an annular communication pipe distributed on the outer periphery of the tower body. A plurality of flange interfaces are arranged in a circumferential array around the tower body on the outer surface of the tower body at the height position of the spray layer. A plurality of branch water pipes are arranged on the annular communication pipe. Each branch water pipe can correspond to the position of one of the flange interfaces. A fixed flange capable of being fixedly matched with the corresponding flange interface is arranged at the end of each branch water pipe. A nozzle inserted into the tower body through the flange interface is arranged at the end of each fixed flange. A plurality of the nozzles are arranged in a circumferential array inside the tower body.

[0007] Specifically, it further includes a spare sealing plate. Each nozzle is detachable relative to the flange interface. The spare sealing plate is used for being fixed with the flange interface after the nozzle is removed so as to realize the sealing fit with the flange interface.

[0008] Specifically, the annular connecting pipe includes an annular pipe body. Each branch water pipe is connected to the annular pipe body. There is a raised portion of the annular pipe body between two adjacent branch water pipes. The raised portion shares the cavity part of the annular connecting pipe. The height of the inner cavity of the raised portion gradually decreases in the direction close to the branch water pipe. A drain pipe is provided at the highest point position of each raised portion, and a sealing cover is provided at the open end of each drain pipe.

[0009] Specifically, a transparent observation window is provided on the drain pipe, and the observation window penetrates through the highest and lowest positions of the drain pipe.

[0010] Specifically, an operation platform is installed on the outer periphery of the tower body and below the annular connecting pipe.

[0011] Specifically, each branch water pipe includes a water connection flange for connecting the annular connecting pipe, a regulating valve, a flow meter, and a pressure gauge.

[0012] Specifically, each branch water pipe further includes a high-pressure resistant rubber hose, and the high-pressure resistant rubber hose is installed in sealing cooperation with a fixed flange.

[0013] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example

[0024] A vertical annular spray washing tower system provided by an embodiment of the present utility model is used for the uniform spraying operation of a washing tower. After problems occur in the operation of individual nozzles, the nozzles can be adjusted and maintained without shutting down the machine, which is beneficial to ensuring the normal operation of each nozzle during the operation of the equipment, avoiding the cumbersome nozzle adjustment steps caused by shutdown and other situations. To realize the structural functions of the system, the system is provided with a tower body 1 and an annular connecting pipe 3 distributed on the outer periphery of the tower body 1. Specifically, a plurality of flange interfaces 2 are arranged in a circumferential array around the tower body 1 on the outer surface of the tower body 1 at the height position of the spray layer. A plurality of branch water pipes 4 are arranged on the annular connecting pipe 3. Here, the annular connecting pipe 3 serves as the main inlet water pipe for supplying cleaning liquid to each branch water pipe 4, or can be used in combination with a dosing device to supply cleaning liquid into the tower body 1. To ensure the accuracy of the supply position, each branch water pipe 4 is arranged to be able to correspond to the position of one of the flange interfaces 2, and a fixed flange 405 capable of being fixedly matched with the corresponding flange interface 2 is arranged at the end of each branch water pipe 4. To realize the spraying function, a nozzle 5 inserted into the tower body 1 through the flange interface 2 is arranged at the end of each fixed flange 405. It should be noted here that the nozzle 5 needs to be fixedly arranged relative to the fixed flange 405 to ensure that when the fixed flange 405 is fixedly installed relative to the flange interface 2, the nozzle 5 can be accurately located at a relatively accurate position inside the tower body 1, and finally realize the circumferential array distribution of a plurality of nozzles 5 inside the tower body 1. Through the above design, when one of the nozzles 5 fails, the corresponding fixed flange 405 can be directly removed to inspect or replace the corresponding nozzle 5, that is, the nozzle 5 can be adjusted individually while other nozzles 5 are working normally, without affecting the continuous progress of the spraying action inside the tower body 1. The maintenance operation is simple and there is no need for additional shutdown processing, which is beneficial to ensuring the normal operation of each nozzle 5 and ensuring the spraying effect, thereby realizing the improvement of the washing efficiency.

[0025] A vertical annular spray washing tower system provided by an embodiment of the present utility model, considering that after the corresponding nozzle 5 is taken out, the position of the flange interface 2 is prone to leaking the incompletely treated gas inside the tower body 1. Therefore, the system can be provided with a spare sealing plate. After each nozzle 5 is arranged to be detachable relative to the flange interface 2, the spare sealing plate is arranged to be fixedly connected with the flange interface 2 after the nozzle 5 is removed, so as to realize the sealing cooperation with the flange interface 2 and avoid the direct leakage of the gas without demisting treatment from the position of the flange interface 2.

[0026] A vertical annular spray washing tower system provided by an embodiment of the present utility model. Considering that if the annular connecting pipe 3 is used as the main water inlet channel, if there is gas in the annular connecting pipe 3, it is easy to cause continuous changes in the hydraulic pressure in the annular connecting pipe 3. That is, in actual use, the spray amount and spray pressure of the nozzle 5 are likely to fluctuate. To avoid this situation, the annular connecting pipe 3 is provided to include an annular pipe body 301. Each branch water pipe 4 is connected to the annular pipe body 301, and a convex portion 302 of the annular pipe body 301 is provided between two adjacent branch water pipes 4. As Figure 3 and Figure 5 shown, the convex portion 302 shares the cavity part of the annular connecting pipe 3. The height of the internal cavity of the convex portion 302 gradually decreases in the direction close to the branch water pipe 4. When there are bubbles in the annular connecting pipe 3, the structure of the convex portion 302 will drive the bubbles to concentrate above the convex portion 302. At this time, by removing the bubbles, the liquid pressure inside the annular connecting pipe 3 can be guaranteed. Therefore, a drain pipe 303 is provided at the highest point of each convex portion 302. When initially replenishing the liquid into the annular connecting pipe 3, allowing the liquid to drain from each drain pipe 303 can ensure the exclusion of gas in the system. After the exclusion, a sealing cover 304 is provided at the open end of each drain pipe 303 to seal the drain pipe 303 and ensure the stability and normality of the hydraulic pressure in the system.

[0027] A vertical annular spray washing tower system provided by an embodiment of the present utility model. To facilitate observing whether there is still residual gas not excluded, a transparent observation window can be provided on the drain pipe 303. The observation window penetrates through the highest and lowest positions of the drain pipe 303 to facilitate the operator to directly observe whether there are bubbles in the liquid path system. If there are, turn the corresponding sealing cover 304 slightly to release the gas, and then tighten it immediately.

[0028] A vertical annular spray washing tower system provided by an embodiment of the present utility model. To facilitate manual maintenance and inspection of each nozzle 5, an operation platform 6 is installed on the outer periphery of the tower body 1 and below the annular connecting pipe 3. Preferably, the operation platform 6 is arranged in a ring shape. For construction operations at a certain height, workers can climb by building a ladder.

[0029] A vertical annular spray washing tower system provided by an embodiment of the present utility model. To ensure the uniformity of water spraying of each branch water pipe 4, each branch water pipe 4 is provided with a water connection flange for connecting the annular communicating pipe 3, a regulating valve 401, a flow meter 402, a pressure gauge 403, etc. Among them, the regulating valve 401 is used to control the flow rate of the corresponding pipeline, the flow meter 402 is used to monitor whether the spray flow rate is normal, and the pressure gauge 403 is used to monitor that the pressure of the branch water pipe 4 does not exceed the threshold. Some of the above components can also be electronic components communicatively connected to the control system to apply data transmission and alarm for convenient on-site inspection operations by personnel in a timely manner.

[0030] A vertical annular spray washing tower system provided by an embodiment of the present utility model. To facilitate the installation and cooperation of the fixed flange 405 and the flange interface 2, each branch water pipe 4 is further provided with a high-pressure resistant rubber hose 404. The high-pressure resistant rubber hose 404 is hermetically fitted with the fixed flange 405. The toughness of the high-pressure resistant rubber hose 404 is utilized to enable the fixed flange 405 and the flange interface 2 to have a certain assembly gap, so as to facilitate the accurate installation of the fixed flange 405 without affecting the conflict between structural components. When removing the nozzle 5, the telescopic and flexible properties of the high-pressure resistant rubber hose 404 can also be used to directly remove the nozzle 5 from the tower body 1.

[0031] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
