Description

Technical Field

[0001] The utility model belongs to the technical field of air treatment, and particularly relates to a drying device for air pollution treatment. Background Technique

[0002] The drying device for air pollution treatment is a device specifically used for drying humid gas in the process of air pollution treatment. The main function of this device is to remove moisture in the gas, further reduce or eliminate pollutants therein, so as to achieve the purpose of improving air quality.

[0003] The existing drying devices for air pollution treatment often directly use desiccants, with large consumption and high cost. It is a difficult problem to judge whether the desiccant is saturated. Once it is saturated but continues to be used, it may reduce the treatment effect and even cause the re-release of pollutants. In addition, the operation of taking out the desiccant is usually rather cumbersome.

[0004] Therefore, in view of the above current situation, there is an urgent need to develop a drying device for air pollution treatment to overcome the deficiencies in current practical applications. Content of the Utility Model

[0005] The purpose of the embodiment of the utility model is to provide a drying device for air pollution treatment, aiming to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A drying device for air pollution control, comprising a bottom plate and a fixing ring. A water tank is placed on the upper end of the bottom plate. The bottom plate and the fixing ring are fixedly connected by a plurality of support plates. The inner wall of the fixing ring is fixedly connected with a working cylinder. The lower end of the working cylinder is fixedly connected with a bottom conical plate. A cold water pipe is fixedly connected inside the working cylinder. The cold water pipe is spirally arranged inside the working cylinder, and both ends of the cold water pipe penetrate through the working cylinder. A first air pipe is nested inside the cold water pipe, and the end of the first air pipe is located inside the working cylinder. The output end of the cold water pipe is fixedly connected with a return pipe, and the other end of the return pipe is located inside the water tank. The end of the first air pipe is fixedly connected with a second air pipe. A drain pipe is fixedly connected to the second air pipe, and the lower end of the drain pipe is located inside the water tank. The output end of the second air pipe is fixedly connected with a third air pipe; A drying cylinder is further arranged inside the working cylinder. A plurality of clamping rings are fixedly connected to the inner wall of the drying cylinder. Drying boxes are placed on the clamping rings. Desiccants are placed inside the drying boxes. A detection box is placed on the last clamping ring. A detection reagent for detecting water is placed inside the detection box; The upper end of the working cylinder is fixedly connected with a top cover through a snap lock. A monitoring camera is fixedly arranged on the top cover. A plurality of exhaust holes are also opened on the top cover; A chiller is also included. The water outlet end of the chiller is fixedly connected with the cold water pipe through a water outlet cold pipe. The water inlet end of the chiller is connected to the water tank through a water inlet heat pipe.

[0008] Further technical solution, the bottom end position of the drying cylinder is lower than the upper end of the third air pipe. The drying cylinder is inclined, and the radius of the lower end is smaller than that of the upper end.

[0009] Further technical solution, a plurality of uniformly distributed holes are opened on the drying box, and handles are fixedly connected to the upper ends of the inner walls of the drying box and the detection box.

[0010] Further technical solution, the monitoring camera is also electrically connected to an alarm.

[0011] The utility model extracts water from the water tank by the chiller and refrigerates it. The flowing cold water in the cold water pipe reduces the temperature of the gas in the first air pipe to achieve condensation, thereby initially removing the moisture in the gas. The condensed water in the first air pipe is transported to the water tank through the drain pipe. The moisture in the gas is absorbed by the desiccant placed in the drying box. The anhydrous copper sulfate placed in the detection box is used to detect whether there is water in the gas. The color change of the anhydrous copper sulfate placed in the detection box is detected by the monitoring camera. The drying box and the detection box are picked up and placed by the handle. The alarm prompts the color change of the anhydrous copper sulfate, having the effects of effectively reducing the usage amount of the desiccant, reducing the cost, and quickly identifying and prompting the saturated water absorption state of the desiccant.

Detailed Description of the Preferred Embodiments

[0019] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0021] Such as Figures 1-5As shown in the figure, an embodiment of the present utility model provides a drying device for air pollution control, including a bottom plate 1 and a fixing ring 3. A water tank 10 is placed on the upper end of the bottom plate 1. The bottom plate 1 and the fixing ring 3 are fixedly connected by a plurality of support plates 2. The inner wall of the fixing ring 3 is fixedly connected with a working cylinder 4. The lower end of the working cylinder 4 is fixedly connected with a bottom conical plate 17. A cold water pipe 5 is fixedly connected in the working cylinder 4 through a clamp (not shown in the figure). The cold water pipe 5 is spirally arranged in the working cylinder 4, and both ends of the cold water pipe 5 penetrate through the working cylinder 4. A first air pipe 6 is nested in the cold water pipe 5, and the end of the first air pipe 6 is located in the working cylinder 4. The cold water pipe 5 reduces the temperature of the gas in the first air pipe 6 through flowing cold water to achieve condensation. The output end of the cold water pipe 5 is fixedly connected with a return pipe 12, and the other end of the return pipe 12 is located in the water tank 10. The end of the first air pipe 6 is fixedly connected with a second air pipe 18, and the second air pipe 18 penetrates through the side wall of the cold water pipe 5. A drain pipe 11 is fixedly connected to the second air pipe 18. The lower end of the drain pipe 11 penetrates through the bottom conical plate 17 and is located in the water tank 10. The drain pipe 11 is used to transport the condensed water in the first air pipe 6 to the water tank 10. The output end of the second air pipe 18 is fixedly connected with a third air pipe 19; A drying cylinder 20 is further arranged in the working cylinder 4, and the drying cylinder 20 is fixedly connected with the inner wall of the working cylinder 4 through steel bars (not shown in the figure). A plurality of clamping rings 21 are fixedly connected to the inner wall of the drying cylinder 20. A drying box 22 is placed on the clamping ring 21. A desiccant is placed in the drying box 22. A detection box 23 is placed on the last clamping ring 21. A detection reagent (not shown in the figure) for detecting water is placed in the detection box 23; The upper end of the working cylinder 4 is fixedly connected with a top cover 13 through a latch (not marked in the figure). A monitoring camera 15 is fixedly arranged on the top cover 13. The monitoring camera 15 is connected to a background system. The monitoring camera 15 is used to detect the color change of the detection reagent placed in the detection box 23. A plurality of exhaust holes 14 are also opened on the top cover 13; A chiller 8 is also included. The water outlet end of the chiller 8 is fixedly connected with a water outlet cold pipe 7. The water outlet cold pipe 7 is fixedly connected with the cold water pipe 5. The water inlet end of the chiller 8 is fixedly connected with a water inlet heat pipe 9. The water inlet heat pipe 9 is connected to the water tank 10 through a valve. The chiller 8 is used to refrigerate the water flowing out of the water tank 10.

[0022] Further, the detection reagent for detecting water placed in the detection box 23 is anhydrous copper sulfate.

[0023] It can be understood that anhydrous copper sulfate turns blue when it meets water; When the top cover 13 is closed, there is an abutment between the upper end of the drying cylinder 20 and the top cover 13, so that gas cannot pass between the top cover 13 and the drying cylinder 20; The intake end of the first air pipe 6 is an air inlet 16, and the gas enters the device from the air inlet 16.

[0024] Furthermore, the bottom end of the drying cylinder 20 is lower than the upper end of the third air pipe 19. The drying cylinder 20 is inclined, and the radius of the lower end is smaller than that of the upper end.

[0025] Furthermore, a plurality of holes are evenly distributed on the drying box 22, and handle 24 is fixedly connected to the upper ends of the inner walls of both the drying box 22 and the detection box 23. The handle 24 is used for convenient picking up and placing.

[0026] Furthermore, the monitoring camera 15 is also electrically connected to an alarm (not shown in the figure), and the alarm is used to prompt the color change of the detection reagent.

[0027] Furthermore, the outlet water cooling pipe 7, the inlet heat pipe 9, the drain pipe 11 and the return pipe 12 are all flexible hoses, and the cold water pipe 5 and the first air pipe 6 are rigid pipes.

[0028] Furthermore, an overflow hole (not shown in the figure) is also provided on the water tank 10, and the overflow hole is used to control the water volume in the water tank 10.

[0029] In the embodiment of the present utility model, the water chiller 8 extracts the water in the water tank 10 and cools it. The flowing cold water in the cold water pipe 5 reduces the temperature of the gas in the first air pipe 6 to achieve condensation, thereby initially removing the moisture in the gas. The condensed water in the first air pipe 6 is transported to the water tank 10 through the drain pipe 11. The moisture in the gas is absorbed by the desiccant placed in the drying box 22. The anhydrous copper sulfate placed in the detection box 23 is used to detect whether there is water in the gas. The monitoring camera 15 detects the color change of the anhydrous copper sulfate placed in the detection box 23. The drying box 22 and the detection box 23 are picked up and placed through the handle 24. The alarm prompts the color change of the anhydrous copper sulfate, which has the effects of effectively reducing the usage amount of the desiccant, reducing the cost, and quickly identifying and prompting the saturated water absorption state of the desiccant.

[0030] The working principle of the present utility model is as follows: First, a certain amount of water is added into the water tank 10 through the overflow hole, and then the chiller 8 is started. The chiller 8 extracts the water in the water tank 10 for refrigeration and transports it to the cold water pipe 5 through the outlet cold water pipe 7. Then, the cold water flows into the return pipe 12 from the other end of the cold water pipe 5 and then into the water tank 10, circulating continuously. During this process, gas enters the first air pipe 6 from the air inlet 16, and then condenses on the inner wall of the first air pipe 6. The water reaches the second air pipe 18 through one end of the first air pipe 6, and then enters the water tank 10 along the drain pipe 11 from the drain pipe 11. The gas in the first air pipe 6 reaches the third air pipe 19 through the second air pipe 18, and then enters the drying cylinder 20 from the upper end of the third air pipe 19. Subsequently, it sequentially passes through the desiccant in the drying box 22 to remove water, and then passes through the hole in the middle of the detection box 23 and is discharged through the exhaust hole 14. In addition, the monitoring camera 15 detects whether the color of the anhydrous copper sulfate in the detection box 23 changes. If the color turns blue, it indicates that the desiccant is saturated, and at this time, the alarm responds.

[0031] The circuits, electronic components, and modules involved are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve improvements to software and methods either.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
