Description

Technical Field

[0001] This utility model relates to the field of pesticide production technology, specifically a heat exchange device for pesticide production. Background Technology

[0002] Pesticides refer to chemically synthesized substances or mixtures of substances derived from organisms, other natural products, or produced using biotechnology, used to prevent, eliminate, or control diseases, insects, weeds, and other harmful organisms that endanger agriculture and forestry, as well as to purposefully regulate, control, and influence the metabolism, growth, development, and reproduction of plants and harmful organisms. In the pesticide production process, tubular heat exchange equipment is required to process pesticides so that they can be produced and put into use.

[0003] Heat exchange is achieved by transferring the temperature of a high-temperature fluid to a lower-temperature fluid through a medium. However, existing heat exchange equipment uses water pipes to transport pesticides for heat exchange. Because the water pipes are circular, their contact area with the pesticides is small, and the pesticides located in the center cannot receive adequate heat exchange, resulting in low heat exchange efficiency. Often, a second heat exchange is required to reach the ideal temperature. At the same time, the medium is usually in a closed container to prevent the medium from heating up or losing heat. However, if the temperature is high during heat exchange, water vapor will be generated and the air pressure will rise. If the pressure is not released in time, the internal air pressure will become too high and the container will burst. However, directly releasing the pressure will cause the humidity of the working environment to increase, resulting in problems such as dampness in the site. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a heat exchange device for pesticide production. The heat exchange efficiency of pesticides is improved by using heat exchange components. The contact area with the medium is increased by using a spiral flat tube, thereby transporting the pesticide in a water flow manner, which expands the heat exchange area of ​​the pesticide and reduces the distance between the pesticide and the flat tube in the middle area, so that heat exchange can be fully achieved. Secondly, the pressure relief component can relieve the pressure of the heat exchange tank and water tank to prevent the internal bursting due to excessive pressure, and separate the moisture in the water vapor to allow dry air to be discharged to avoid making the working area damp.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0011] Furthermore, a water pump is provided on one side of the water tank, with one end of the water pump extending into the heat exchange zone and one end of the water pump communicating with the inside of the water tank. A return water pipe is provided inside the heat exchange zone, with the bottom end of the return water pipe connected to the top of the water tank.

[0012] Furthermore, a cavity can be formed between the two fixing rings and the hollow tube and the separation cylinder. The two partition plates b can separate the cavity into an air inlet chamber and an air outlet chamber. An air inlet and an air outlet are fixedly connected to the outside of the separation cylinder, and a drain pipe is fixedly connected to the bottom of the separation cylinder.

[0015] The beneficial effects of this utility model are:

[0016] The advantage of this utility model is that it improves the heat exchange efficiency of pesticides by using heat exchange components, increases the contact area with the medium by using spiral flat tubes, and then transports the pesticides in a water flow manner, thereby expanding the heat exchange area of ​​pesticides and reducing the distance between the pesticides and the flat tubes in the middle area, so that heat exchange can be fully achieved.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figures 1-5 As shown, a heat exchange device for pesticide production includes: a support frame 1, a heat exchange tank 11 fixedly installed on the top of the support frame 1, a water tank 12 fixedly installed at the bottom inside the support frame 1, and an electric heating tube 13 inside the water tank 12; a heat exchange assembly located inside the heat exchange tank 11 for heat exchange of pesticides; and a pressure relief assembly located on the top of the water tank 12 for pressure relief of the heat exchange tank 11 and the water tank 12.

[0028] When in use, water is added to the water tank 12. When cooling the pesticide, the water in the water tank 12 is directly sent to the heat exchange tank 11. When heating the pesticide, the electric heating tube 13 is turned on to heat the water in the water tank 12. After heating to a suitable temperature, the hot water is sent to the heat exchange tank 11. The heat exchange components can exchange heat with the pesticide, increasing the surface area of ​​the pesticide and thus improving the heat exchange efficiency of the pesticide. When heating the pesticide, the pressure relief components can relieve the pressure in the heat exchange tank 11 and the water tank 12 to avoid excessive pressure inside the heat exchange tank 11 and the water tank 12.

[0029] Example 2

[0030] Based on Embodiment 1, the heat exchange assembly includes: a flat tube 2, a partition plate a21, a heat exchange zone 22, a transfer cylinder 23, a connecting pipe 24, and a connecting pipe 25. The heat exchange tank 11 has a flat tube 2 inside, which is spirally arranged. Partition plates a21 are fixedly connected to both ends of the flat tube 2. The two partition plates a21 are fixedly connected to the inner wall of the heat exchange tank 11, forming a heat exchange zone 22 between the two partition plates a21. A transfer cylinder 23 is fixedly installed on the opposite side of the two partition plates a21, and the two transfer cylinders 23 are separated on opposite sides. Multiple connecting pipes 24 are fixedly connected to the flat pipe 2. The connecting pipes 24 on both sides are connected to the opposite ends of the flat pipe 2. The two ends of the transfer cylinder 23 are fixedly connected to the connecting pipes 25. The opposite ends of the two connecting pipes 25 pass through the heat exchange tank 11 and extend to the outside. A water pump 26 is provided on one side of the water tank 12. One end of the output end of the water pump 26 extends into the heat exchange zone 22. One end of the input end of the water pump 26 is connected to the inside of the water tank 12. A return water pipe 27 is provided inside the heat exchange zone 22. The bottom end of the return water pipe 27 is connected to the top of the water tank 12.

[0031] When exchanging heat with pesticides, water pump 26 is turned on to draw water from inside water tank 12 and deliver it to heat exchange zone 22. Water enters from the bottom and flows back into water tank 12 after overflowing the top of return pipe 27, thus forming a water circulation. Then, pesticides are input from one end of connecting pipe 25 into transfer cylinder 23 and then distributed into multiple connecting pipes 24. The pesticides then flow into flat pipe 2 from the connecting pipes 24. Flat pipe 2 can spread the pesticides out, thereby increasing the contact area between the pesticides and flat pipe 2. The spiral flat pipe 2 has a large contact area with water, which can improve the heat exchange efficiency of pesticides and flat pipe 2 and avoid insufficient cooling and heating of pesticides. After heat exchange, the pesticides flow out from the other side of connecting pipe 25.

[0032] Example 3

[0033] Based on Embodiment 1, the pressure relief assembly includes: a separation cylinder 3, a hollow pipe 31, fixing rings 32, partition plates b33, a mist eliminator 34, and interceptor plates 35. The separation cylinder 3 is fixedly installed on the top of the water tank 12. A hollow pipe 31 is located inside the separation cylinder 3. Two fixing rings 32 are fixedly connected to the periphery of the hollow pipe 31 and the separation cylinder 3. Two partition plates b33 are fixedly connected between the two fixing rings 32 and the separation cylinder 3. A mist eliminator 34 is located inside the hollow pipe 31. Multiple interceptor plates 35 arranged in a herringbone structure are located below the mist eliminator 34. A cavity can be formed between the two fixing rings 32, the hollow pipe 31, and the separation cylinder 3. The partition b33 can separate the cavity into an air inlet chamber 36 and an exhaust chamber 37. An air inlet 38 and an exhaust outlet 39 are fixedly connected to the outside of the separator 3. A drain pipe 310 is fixedly connected to the bottom of the separator 3. The air inlet 38 is connected to the air inlet chamber 36 and the exhaust outlet 39 is connected to the exhaust chamber 37. The bottom end of the drain pipe 310 extends into the water tank 12. One end of the air inlet 38 is fixedly connected to an air pipe 311. One end of the air pipe 311 extends into the heat exchange zone 22. A baffle 312 is fixedly connected to the top of the air inlet chamber 36. An air hole a313 is opened at the bottom of the air inlet chamber 36 and an air hole b314 is opened at the top of the exhaust chamber 37.

[0034] During heating, the steam and gas pressure inside the heat exchange tank 11 enter the intake chamber 36 through the air pipe 311 and the air inlet 38. The steam first collides with the baffle 312, and some water vapor will condense on the baffle 312. The steam flows into the cavity at the bottom of the separator 3 through the air hole a313 at the bottom of the intake chamber 36. The steam then enters the hollow pipe 31 and comes into contact with the interceptor plate 35 to continue condensing. With the help of the mist eliminator 34, the water is separated, and the gas enters the cavity at the top of the separator 3 through the mist eliminator 34. The condensed water falls under the action of gravity and falls back into the water tank 12 through the drain pipe 310. The steam in the water tank 12 enters the cavity at the bottom of the separator 3 through the drain pipe 310. The separated gas enters through the air hole b314 at the top of the exhaust chamber 37 and is discharged through the exhaust port 39 to complete the depressurization and separate the water to prevent the working environment from being humid.
