Description

Technical Field

[0001] The present application relates to the field of water treatment, and in particular to a cooling exchanger for water treatment. Background Art

[0002] In the process of granulating and producing raw materials of plastics and other equipment, circulating water is needed to cool the plastic or perform auxiliary work. The circulating water will be recycled through a water treatment device, especially when used in the production of food-grade plastic products. Pure water is used, but the amount of pure water is small and needs to be recycled repeatedly. However, the calorie content of the circulating water is too high after use, and it is difficult to provide a stable cooling effect by continuing to use it in a circular manner. Summary of the invention

[0003] In order to improve the above problems, the present application provides a cooling exchanger for water treatment.

[0004] The present application provides a cooling exchanger for water treatment using the following technical solution:

[0005] A cooling exchanger for water treatment comprises a conveying member and an outer member; the interior of the conveying member is a conveying space for providing circulating water; the inner diameter of the outer member is larger than the outer diameter of the conveying member, and the outer member wraps the conveying member; a storage cavity is provided in the outer member, cooling water is stored in the storage cavity, the cooling water contacts the outer wall of the conveying member, and exchanges heat with the circulating water through the outer wall of the conveying member.

[0006] By adopting the above technical solution, the cooling water in the storage chamber is utilized to make the cooling water contact with the outer wall of the conveying member, and the circulating water in the conveying member flows continuously, so that the heat is continuously exchanged with the cooling water, thereby reducing the heat of the circulating water to ensure the cooling effect.

[0007] Optionally, the conveying member is provided with several layers, each layer is provided with several bending points in the horizontal direction, and connecting members are provided between adjacent layers to connect with each other; the bending points separate the conveying members into N+1 groups, and N is the number of the bending points.

[0008] By adopting the above technical solution, the conveying parts are provided with several layers, that is, multiple layers of conveying parts are provided to increase the cooling area. Each layer is connected by connecting parts, so that the circulating water can flow stably from top to bottom to all layers, and is cooled by the outer package during the flow process, thereby improving the cooling efficiency. The number of bending points will divide the conveying parts into N+1 groups. The more components there are, the larger the flow range, the larger the cooling area, the longer the time required for the circulating water to circulate once, and the more stable the cooling effect.

[0009] Optionally, a plurality of the outer packaging members are provided, and a single outer packaging member corresponds one-to-one to a single group of the conveying members, and each outer packaging member wraps a single group of the conveying members.

[0010] By adopting the above technical solution, the overall outer packaging is divided into several parts, and each outer packaging is connected to a corresponding group of conveying parts. The purpose is to save consumables. If the entire layer of conveying parts is wrapped by the same outer packaging, there will be some spaces where cooling water cannot contact the outer wall of the conveying parts. Not only will the consumables be too large, but the cooling water will also be unable to fully exchange heat, resulting in waste.

[0011] Optionally, in the single-layer conveying member, adjacent outer packaging members are provided with flow guide members for conduction.

[0012] By adopting the above technical solution, the single-layer conveying part uses the guide part to connect the adjacent outer packaging parts, so that the cooling water of the single layer can circulate with each other. At the same time, it is also convenient to pour cooling water. One outer packaging part can be directly poured and the guide part can be used to fill other outer packaging parts, thereby improving convenience of use.

[0013] Optionally, the conveying component and the outer component that initially contacts become the first outer component, and the first outer component is provided with a spray component and a supplement component; one end of the supplement component is connected to a water pipe, and the other end is connected to the first outer component; the spray component is connected to the first outer component.

[0014] By adopting the above technical scheme, the spray component can extract the cooling water in the first outer packaging component and spray it out in the form of mist. The mist after forming comes into contact with other outer packaging components and unwrapped conveying components, so that after the surfaces of other outer packaging components and unwrapped conveying components come into contact with the mist, the mist evaporates rapidly due to heat, and the evaporation absorbs heat, thereby accelerating the cooling of other outer packaging components or unwrapped conveying components and further improving the cooling effect. The sprayed cooling water is replenished by the replenishing component.

[0015] Optionally, the spray component includes an extraction portion, a connecting portion and an atomizing nozzle; the extraction portion is connected to the outer wall of the first outer packaging component and communicated with the first outer packaging component; the connecting portion is connected to the extraction portion; and the atomizing nozzle is communicated with the connecting portion.

[0016] By adopting the above technical solution, the cooling water in the first outer package is extracted by the extraction part and transported to the atomizing nozzle by the connecting part, and the atomizing nozzle sprays water mist to cool the outer surface of the outer package and the unwrapped conveying part, thereby improving the cooling efficiency during the water circulation process.

[0017] Optionally, each layer of the conveying member is provided with at least one atomizing nozzle.

[0018] By adopting the above technical solution, each layer of conveying parts is provided with at least one atomizing nozzle, so that the atomizing nozzle can fully spray onto each layer of conveying parts, thereby improving the efficiency of heat exchange.

[0019] Optionally, each of the bending points is not wrapped by an outer package, and each of the bending points is provided with a temperature sensing component.

[0020] By adopting the above technical solution, the temperature sensing element can not only observe the specific temperature value of each bending point, and observe the cooling efficiency based on the temperature value, but also remind nearby workers not to touch the bending point due to high temperature, thereby improving safety.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. Use the cooling water in the storage chamber to make the cooling water contact with the outer wall of the conveying part, and the circulating water in the conveying part flows continuously, so that the heat is continuously exchanged with the cooling water, thereby reducing the heat of the circulating water to ensure the cooling effect;

[0023] 2. Setting several layers of conveying parts means setting multiple layers of conveying parts to increase the cooling area. Each layer is connected by connecting parts, so that the circulating water can flow stably from top to bottom to all layers. During the flow, it is cooled by the outer parts, thereby improving the cooling efficiency. The number of bending points will divide the conveying parts into N+1 groups. The more groups there are, the larger the flow range and the cooling area. The longer the time required for the circulating water to circulate once is, and the more stable the cooling effect is.

[0024] 3. Divide the overall outer package into several parts, and each outer package is connected to a group of conveying parts respectively, so as to save consumables. If the entire layer of conveying parts is wrapped by the same outer package, there will be some spaces where cooling water cannot contact the outer wall of the conveying parts, which will not only cause excessive consumables but also cause the cooling water to fail to fully exchange heat, resulting in waste;

[0025] 4. The single-layer conveying parts use the guide pieces to conduct the adjacent outer packages, so that the cooling water of the single layer can circulate with each other. At the same time, it is also convenient to pour cooling water. When pouring one outer package, the guide pieces can be used to fill the other outer packages, which improves the convenience of use.

In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0035] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0036] The embodiment of the present application discloses a cooling exchanger for water treatment.

[0037] A cooling exchanger for water treatment is used for cooling circulating water during plastic or plastic granulation. The circulating water is used to cool plastic or plastic products, especially for food-grade circulating water. Food-grade circulating water is pure water with high purity and is difficult to produce. Therefore, it is not convenient for one-time use and needs to be recycled. In order to ensure that the cooling effect of the circulating water is stable during circulation cooling, this cooling exchanger is used.

[0038] refer to Figure 1 As shown, the cooling exchanger includes a conveying member and an outer member; the interior of the conveying member is a conveying space for providing circulating water. The conveying member can be a conveying pipe, and the pipe wall of the water pipe needs to be strictly regulated. When the pressure is met, it needs to be thin enough to ensure sufficient heat exchange. The conveying space inside the conveying pipe can convey circulating water. One end of the conveying pipe is connected to an external water treatment device, and the other end is connected to a granulator and other production equipment. The circulating water treated by the external water treatment device continues to be conveyed to the granulator and other production equipment, so that an overall water circulation is formed.

[0039] Among them, the conveying parts generally adopt a circulating water flow method from top to bottom. The circulating water flow from top to bottom can use gravity to flow, and there is no need to apply additional other extraction equipment to provide circulating water flow, thereby reducing energy loss.

[0040] refer to Figure 2 As shown, the inner diameter of the outer packaging part is larger than the outer diameter of the conveying part, and the outer packaging part wraps the conveying part. The outer packaging part can be an outer packaging tube or an outer packaging tube, and the inner diameter of the outer packaging tube is larger than the outer diameter of the conveying part, so that the outer packaging tube can be sleeved on the conveying part, and welding seals are provided at both ends.

[0041] A storage chamber is provided in the outer package, in which cooling water is stored. The storage chamber is the space between the inner wall of the outer package and the outer wall of the conveying component. The cooling water is stored in this space. The cooling water contacts the outer wall of the conveying component, and the circulating water in the conveying component flows continuously, so that the heat is continuously exchanged with the cooling water, thereby reducing the heat of the circulating water to ensure the cooling effect.

[0042] The circulating water may be food-grade purified water, and the cooling water does not need to be high-quality purified water because it does not come into contact with or mix with the circulating water. Ordinary cooling water such as tap water may be used for cooling.

[0043] Among them, an infusion port and a connecting valve are opened on the outer package. The infusion port is closed by the connecting valve, and the infusion port is used to transport cooling water.

[0044] In some embodiments, reference Figure 1 As shown, the conveying member is provided with several layers, each layer is provided with several bending points in the horizontal direction, and connecting parts are arranged between adjacent layers to connect with each other. The conveying member is provided with several layers, which means that multiple layers of conveying members are provided to increase the cooling area. Each layer is connected by connecting parts, so that the circulating water can flow stably from top to bottom to all layers, and is cooled by the outer package during the flow process, thereby improving the cooling efficiency. This application takes a conveying member with four layers as an example.

[0045] The bending points separate the conveying parts into N+1 groups, where N is the number of bending points. A single bending point can divide the conveying parts into two, forming two groups, and the next bending point will share a group of conveying parts with the previous bending point. Therefore, the number of bending points will divide the conveying parts into N+1 groups. The more components the conveying parts are divided into, the larger the flow range, the larger the cooling area, the longer the circulating water needs to flow for one circle, and the more stable the cooling effect. This application takes a single layer with one bending point as an example.

[0046] Among them, when multiple layers are set up, additional support frames can be set outside the outer packaging for support to avoid excessive pressure on the conveying parts on the bottom layer due to too many layers.

[0047] Furthermore, several outer packaging parts are provided, and a single outer packaging part corresponds to a single group of conveying parts one by one, and each outer packaging part wraps a single group of conveying parts, dividing the overall outer packaging part into several parts, and each outer packaging part corresponds to and is connected to a group of conveying parts. The purpose is to save consumables. If the entire layer of conveying parts is wrapped by the same outer packaging part, there will be some spaces where cooling water cannot contact the outer wall of the conveying parts. Not only will the consumables be too large, but the cooling water will also not be able to fully exchange heat, resulting in waste.

[0048] Among them, in the single-layer conveying part, adjacent outer packaging parts are provided with guide parts for conduction. The single-layer conveying part uses the guide parts to conduct adjacent outer packaging parts, so that the cooling water of the single layer can circulate with each other. At the same time, it is also convenient to pour cooling water. One outer packaging part can be directly poured and the guide parts can be used to fill other outer packaging parts, thereby improving convenience of use.

[0049] In some embodiments, reference Figure 3As shown, the outer package that the conveying member initially contacts becomes the first outer package, that is, the first outer package that the conveying member passes through after conveying the circulating water from the granulator and other equipment, and thus becomes the first outer package.

[0050] The first outer package is provided with a spray component and a supplementary component; one end of the supplementary component is connected to a water pipe, and the other end is connected to the first outer package. The supplementary component can adopt a supplementary pipe, and the supplementary pipe is connected to tap water or other cooling water pools. A water pump can be added if necessary. If the water pressure is sufficient, there is no need to add a water pump. The supplementary pipe can be connected to the infusion port to supplement the cooling water in the first outer package.

[0051] The spray component is connected to the first outer package, and can extract the cooling water in the first outer package and spray it out in the form of mist. The mist after forming comes into contact with other outer packages and unwrapped conveying parts, so that after the surfaces of other outer packages and unwrapped conveying parts come into contact with the mist, the mist evaporates rapidly due to heat, and the evaporation absorbs heat, thereby accelerating the cooling of other outer packages or unwrapped conveying parts and further improving the cooling effect.

[0052] The purpose of using the first outer package is that the first outer package is the outer package that initially contacts with the conveying member and performs heat exchange. When it initially contacts with the conveying member, it is also the position where the circulating water in the conveying member contains the highest amount of heat. Therefore, the cooling water at this point is easily heated after heat exchange and is not suitable for subsequent cooling. Therefore, the cooling water in the first outer package is extracted by using a spray component and sprayed out in the form of a spray. The formed spray of the cooling water increases the contact area with the air, so that each water mist molecule is cooled in the air and finally falls on other outer packages and the outer surface of the unwrapped conveying member for evaporative cooling. The cooling water extracted in the first outer package is replenished by the replenishing component to ensure the stability of the heat exchange in the first outer package.

[0053] Among them, the spray component adopts intermittent spraying, so it will not spray all the time, ensuring that the cooling water in the first outer package has completed heat exchange before being sprayed out by the spray component. The interval time can be any specified time from 10 seconds to 1 minute, and no excessive restrictions are made here. At the same time, the duration of the spray can also be 5 seconds to 10 seconds, and the specific duration is not too limited here.

[0054] For further reference, Figure 3 As shown, the spray component includes an extraction part, a connecting part and an atomizing nozzle; the extraction part is connected to the outer wall of the first outer package and is communicated with the first outer package. The extraction part can adopt a small water pump to provide a pumping effect. The specific position of the extraction part is located at one end of the first outer package away from the initial contact point with the conveying member, so that the first outer package can provide complete heat exchange, so that the water in the conveying member is cooled.

[0055] The connection part is connected to the extraction part, and the connection part can adopt a water spray pipe. The conveying parts adopt a circulating water conveying method from top to bottom, and when the conveying parts are divided into several layers, the connection pipe is extended from top to bottom and spreads to several layers of conveying parts.

[0056] The atomizing nozzle is connected to the connecting part and communicated with the connecting part, so that the cooling water extracted by the extraction part can be directly transported to the atomizing nozzle through the connecting part. The atomizing nozzle is provided with a plurality of atomizing holes, so that the cooling water can be squeezed out from the atomizing holes to form water mist.

[0057] Specifically, the cooling water in the first outer package is extracted by the extraction part and transported to the atomizing nozzle through the connection part, and the atomizing nozzle sprays water mist to cool the outer surface of the outer package and the unwrapped conveying part, thereby improving the cooling efficiency during the water circulation process.

[0058] Among them, after several layers of conveying members are penetrated by the connecting part, each layer of conveying members is provided with at least one atomizing nozzle, so that the atomizing nozzle can fully spray on each layer of conveying members, thereby improving the efficiency of heat exchange.

[0059] In some embodiments, reference Figure 3 As shown, each bending point is not wrapped by an outer casing, and each bending point is provided with a temperature sensing component. The temperature sensing component can be a temperature sensor, and a display screen can be provided on the surface of the temperature sensor. The temperature sensing component can not only observe the specific temperature value of each bending point, but also observe the cooling efficiency according to the temperature value, and can also remind nearby workers not to touch the bending point due to high temperature, thereby improving safety.

[0060] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
