Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a heat exchanger for a gas-fired intensive drying room. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers are widely used as heaters, coolers, condensers, evaporators, and reboilers.

[0003] However, existing heat exchangers for gas-fired intensive drying ovens are not effective enough in purifying and exchanging gas; therefore, they do not meet current requirements. To address this, we propose a new heat exchanger specifically designed for gas-fired intensive drying ovens. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a heat exchanger specifically for gas-fired intensive drying ovens.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A heat exchanger for a gas-fired high-density drying oven includes a main body, with connecting plates on both sides of the main body. One side of one connecting plate has an air inlet pipe, and the other side of the connecting plate has an exhaust pipe. A water tank is provided on the lower surface of the main body, with support columns evenly arranged on the outer side of the water tank. A fixing plate is provided on the inner side of the main body, with heat pipes evenly arranged on the inner side of the fixing plate.

[0007] Preferably, each row of heat pipes is provided with a water pipe on its outer side, the inner surface of the water pipe is uniformly provided with spray heads, the lower end of the water pipe is provided with a connecting pipe, the lower ends of the connecting pipe are provided with water pumps, the inner side of the water tank is provided with a water trough, the lower end of the water pipe is provided with a limit plate, and both ends of the limit plate are provided with electric slide rails.

[0008] Preferably, both the intake pipe and the exhaust pipe are provided with filters on their inner sides. A guide plate is provided below the filter on the intake pipe side, and a collection groove is provided at one end of the guide plate. An activated carbon adsorption mesh is provided on the inner side of the connecting plate on the intake pipe side, and a bamboo charcoal filter layer is provided on the inner side of the connecting plate on the exhaust pipe side.

[0009] Preferably, one side of the connecting plate is completely fitted to the outer surface of the main body, and the connecting plate is fixed to the main body by a welding machine.

[0010] Preferably, the lower end of the water pipe passes through the limiting plate and is fixed to the outer surface of the main body by screws.

[0011] Preferably, a sealing cap is provided on one side of the collection tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a filter screen installed inside the inlet pipe and a collection tank and guide plate installed below the filter screen. The filter screen can filter impurities in the gas, and the collection tank and guide plate can collect the impurities for unified treatment. Then, the activated carbon adsorption screen installed on one side of the filter screen increases the absorption of harmful substances inside the gas, thereby improving the purification effect of the device on the gas.

[0014] 2. In this invention, after the gas enters the heat pipe, a water pipe and a connecting pipe and a water pump are installed on the outside of each row of heat pipes. The water pump can quickly deliver water into the water pipe. The limiting plate and electric slide rail installed below the water pipe can move the spray head on the inner surface of the water pipe while spraying, so as to achieve uniform spraying of the heat pipe and improve the cooling effect of the heat pipe. By setting a bamboo charcoal filter layer between the exhaust pipe and the connecting plate, the gas can be dehumidified and odors removed, which can improve the purification effect of the device on the gas.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figure 1 and Figure 2 As shown, the present invention discloses a heat exchanger for a gas-fired intensive drying oven, comprising a main body 1, with connecting plates 2 on both sides of the main body 1. One side of one connecting plate 2 is provided with an air inlet pipe 5, and the other side of the connecting plate 2 is provided with an exhaust pipe 3. A water tank 8 is provided on the lower surface of the main body 1, with support columns 4 evenly arranged on the outer side of the water tank 8. A fixing plate 7 is provided on the inner side of the main body 1, with heat pipes 6 evenly arranged on the inner side of the fixing plate 7.

[0022] As a preferred technical solution in this embodiment, such as Figure 3 As shown, each row of heat pipes 6 is equipped with a water pipe 9 on its outer side. Spray heads 10 are evenly distributed on the inner surface of the water pipe 9. A connecting pipe 13 is provided at the lower end of the water pipe 9. A water pump 14 is provided below both ends of the connecting pipe 13. A water tank 15 is provided inside the water tank 8. A limiting plate 11 is provided on the outer side of the lower end of the water pipe 9. Electric slide rails 12 are provided at both ends of the limiting plate 11. By using the electric slide rails 12 on both sides of the limiting plate 11, the spray heads 10 on the inner surface of the water pipe 9 can move and spray at the same time, so as to achieve uniform spraying of the heat pipe 6 and improve the cooling effect of the heat pipe 6.

[0023] As a preferred technical solution in this embodiment, such as Figure 4 As shown, filters 16 are installed on the inner sides of both the intake pipe 5 and the exhaust pipe 3. A guide plate 17 is installed below the filter 16 on the intake pipe 5 side, and a collection groove 18 is installed at one end of the guide plate 17. An activated carbon adsorption net 19 is installed on the inner side of the connecting plate 2 on the intake pipe 5 side, and a bamboo charcoal filter layer 20 is installed on the inner side of the connecting plate 2 on the exhaust pipe 3 side. The activated carbon adsorption net 19 can absorb harmful substances in the gas, and the bamboo charcoal filter layer 20 can absorb the odor of the gas discharged from the gas-fired heating oven, thus improving the purification effect of the device on the gas.

[0024] Working principle: In use, one end of the air inlet pipe 5 is connected to the drying oven. The air inlet pipe 5 is connected to a filter 16 located inside, and a collection trough 18 and guide plate 17 located below the filter 16. The filter 16 filters impurities from the gas, and the collection trough 18 and guide plate 17 collect these impurities for unified processing. Then, an activated carbon adsorption mesh 19 located on one side of the filter 16 further absorbs harmful substances from the gas, improving the purification effect. After the gas enters the heat pipes 6, the activated carbon adsorption mesh 19 located on the outside of each row of heat pipes 6 further enhances the purification effect. The water pipe 9, the connecting pipe 13 at the lower end of the water pipe 9, and the water pump 14 are used to quickly deliver water into the water pipe 9. The limiting plate 11 and the electric slide rail 12 at the lower end of the water pipe 9 are used to move the spray head 10 on the inner surface of the water pipe 9 while spraying water, so as to achieve uniform spraying of the heat pipe 6 and improve the cooling effect of the heat pipe 6. By setting the bamboo charcoal filter layer 20 between the exhaust pipe 3 and the connecting plate 2, the bamboo charcoal filter layer 20 can dehumidify the gas and remove the odor from the gas, thereby improving the purification effect of the device on the gas.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
