Description

Technical Field

[0001] This utility model belongs to the field of spray tank technology, specifically relating to a tank top water vapor treatment device. Background Technology

[0002] In the production of polyimide films, the cast film needs to be dried and cured in a drying oven. Because the film slurry contains chemical additives, the exhaust gas generated during drying must be treated before being released into the atmosphere. The current method involves discharging the exhaust gas into a spray tank via a fan to remove impurities. However, due to the high temperature of the exhaust gas (even after spraying, it remains at 40-45°C), and the exhaust gas further increases the temperature inside the spray tank, leading to a higher water vapor content. This water vapor contains impurities, and releasing exhaust gas with a large amount of water vapor into the environment is equivalent to releasing these impurities into the environment as well, which does not meet environmental protection requirements. Utility Model Content

[0003] This utility model provides a tank top water vapor treatment device to solve the technical problem that the exhaust gas after treatment by the existing spray tank still contains a large amount of water vapor, which does not meet the environmental protection requirements. This utility model includes: a transition section, which has flange openings at both its upper and lower ends; The first finned heat exchange section is located above the transition section; The condensation section is located above the first finned heat exchange section; The second finned heat exchange section is located above the condensation section; The discharge section is located above the second finned heat exchange section; Both the first fin heat exchange section and the second fin heat exchange section include a plurality of equidistantly arranged bent fins, and the bending directions of the bent fins in the first fin heat exchange section and the second fin heat exchange section are opposite.

[0004] This invention uses multiple heat exchange processes to cool the exhaust gas discharged from the spray tank in multiple stages, lowering the exhaust gas temperature and causing the water vapor in it to condense into droplets, which then fall back into the spray tank, thereby improving the purity of the exhaust gas and meeting environmental protection requirements.

[0005] Furthermore, an adsorption section is provided between the first finned heat exchange section and the condensation section, and the adsorption section is provided with adsorption material. The beneficial effect of this step is that the adsorption material is used to absorb water vapor in the exhaust gas, thereby reducing the workload of the condensation section.

[0006] Furthermore: Both the first fin heat exchange section and the second fin heat exchange section include a first frame plate. The side of the first frame plate has several insertion holes. The bent fins are inserted into the corresponding insertion holes. Both ends of the bent fins extend out of the first frame plate. The beneficial effect of this step is that the bent fins can be detached from the first fin heat exchange section and the second fin heat exchange section, which facilitates daily cleaning and maintenance.

[0007] Furthermore, the edge of the insertion hole is provided with a sealing strip. The beneficial effect of this step is that the sealing strip can prevent exhaust gas from escaping from the gap between the insertion hole and the bent fin, and can also fix the bent fin, preventing it from vibrating and making noise under airflow disturbance.

[0008] Furthermore: the condensing section includes a second frame plate, the side of which is provided with an opening, and a condenser is inserted into the opening. The beneficial effect of this step is that it facilitates the removal of the condenser for routine maintenance.

[0009] Furthermore: the discharge section includes a third frame plate, and a top cover is fitted onto the top of the third frame plate. The top cover is ridge-shaped. The beneficial effect of this step is that the top cover can block rainwater, etc.

[0010] Furthermore: the first frame plate, the second frame plate, the third frame plate, and the transition section are all connected in pairs with a sealing connection. The beneficial effect of this step is that it can achieve the function of sealing the pipeline.

[0011] Furthermore, the transition section is shaped like a larger top and a smaller bottom, which has the beneficial effect of reducing the exhaust gas emission speed.

[0012] The beneficial effects of this utility model are: 1. This application reduces the exhaust gas temperature through multiple condensation stages consisting of a first fin heat exchange section, a condensation section, and a second fin heat exchange section, allowing the water vapor contained in the exhaust gas to condense into droplets, thus preventing water vapor from being discharged with the exhaust gas and ensuring that the exhaust gas emissions meet environmental protection requirements. 2. An adsorption section is also added between the first fin heat exchange section and the condensation section. The adsorption material absorbs some of the water vapor to reduce the workload of the condenser and prevent the water vapor in the exhaust gas from not being completely condensed. 3. Both the bent fins and the condenser can be pulled out from the side, making daily cleaning and maintenance convenient. Attached Figure Description

It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0017] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0019] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0021] Implementation of this application, for example Figures 1-3 As shown, the water vapor treatment device on the top of the tank provided in this application is generally installed on the top of the spray tank and connected to the exhaust gas discharged from the spray tank.

[0022] This application includes: a transition section 1, which has flanges at both its upper and lower ends; The first finned heat exchange section 2 is located above the transition section 1; The condensation section 3 is located above the first finned heat exchange section 2; The second finned heat exchange section 4 is located above the condensation section 3; The discharge section 5 is located above the second finned heat exchange section 4; Both the first fin heat exchange section 2 and the second fin heat exchange section 4 include a plurality of equidistantly arranged bent fins 21, and the bending directions of the bent fins 21 in the first fin heat exchange section 2 and the second fin heat exchange section 4 are opposite.

[0023] This invention utilizes multiple heat exchange processes to cool the exhaust gas discharged from the spray tank in multiple stages, lowering the exhaust gas temperature. The water vapor in the exhaust gas condenses into droplets and falls back into the spray tank, improving the purity of the exhaust gas and meeting environmental protection requirements. The opposite bending direction of the bent fins 21 increases the resistance to the upward emission of the exhaust gas and extends the flow path, ensuring that the exhaust gas is fully cooled and the contained water vapor is completely cooled.

[0024] Based on the above technical solution, an adsorption section is further provided between the first finned heat exchange section 2 and the condensation section 3. The adsorption section contains adsorption material, which absorbs water vapor in the exhaust gas in advance, reducing the workload of the condensation section 3. The adsorption material is generally graphite, bamboo charcoal, or other porous materials with a large specific surface area, and these materials are supported by a wire mesh demister.

[0025] Based on the above technical solution, both the first fin heat exchange section 2 and the second fin heat exchange section 4 include a first frame plate 22. The side of the first frame plate 22 is provided with several insertion holes, and the bent fins 21 are inserted into the corresponding insertion holes. Both ends of the bent fins 21 extend out of the first frame plate 22. Firstly, the two ends of the bent fins 21 extend out to allow the bent fins 21 to exchange heat with the external environment, i.e., air cooling, so as to reduce the temperature of the bent fins 21 themselves. Secondly, the bent fins 21 can be removed from the first fin heat exchange section 2 and the second fin heat exchange section 4 for easy daily cleaning and maintenance (after long-term use, the surface of the bent fins 21 will inevitably have dirt, etc., which will affect the heat exchange effect).

[0026] Based on the above technical solution, the edge of the socket is provided with a sealing strip. The sealing strip is generally a U-shaped or C-shaped groove strip that can fit around the edge of the socket and shorten the gap of the socket (generally less than the plate thickness of the bent fin 21). The sealing strip can prevent exhaust gas from escaping from the gap between the socket and the bent fin 21, and can also fix the bent fin 21 to prevent it from vibrating and making noise under airflow disturbance.

[0027] Based on the above technical solution, the condensing section 3 includes a second frame plate 32, the side of the second frame plate 32 is provided with an opening, and a condenser 31 is inserted into the opening. The condenser 31 generally needs to be connected to an external cooling water pipe to efficiently cool the exhaust gas using low-temperature water. The condenser 31 is connected to the second frame plate 32 with a drawer-type installation structure, which makes it easy to remove the condenser 31 for daily cleaning and maintenance.

[0028] Based on the above technical solution, the discharge section 5 includes a third frame plate 52, and a top cover 51 is fitted on the top of the third frame plate 52. The top cover 51 is ridge-shaped and can block rainwater and prevent the accumulation of rainwater and debris.

[0029] Based on the above technical solution, the first frame plate 22, the second frame plate 32, the third frame plate 52 and the transition section 1 are all connected in pairs with a sealing connection to achieve a sealing effect and prevent exhaust gas leakage.

[0030] Based on the above technical solution, the transition section 1 is shaped like a larger top and a smaller bottom. After the exhaust gas enters the device, the space suddenly becomes larger, the gas pressure of the exhaust gas decreases, and the flow rate slows down, which plays a role in reducing the exhaust gas emission speed.

[0031] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
