Description

Technical Field

[0001] This utility model belongs to the technical field of heating equipment and relates to a heating device. Background Technology

[0002] In order to save energy, the flue gas generated by combustion equipment such as boilers has a high heat value during factory production and processing. Therefore, existing equipment is usually set up to use the heat of flue gas for heating, thereby achieving the purpose of saving energy.

[0003] Existing heating equipment, such as Chinese patent application [202322138052.2], discloses a stainless steel high-efficiency heating finned tube, which includes a heating tube welded together from outer fins and pipes, and a central shaft welded together from small-pitch fins, a mandrel, and large-pitch fins. The central shaft is installed inside the heating tube. The outer diameter of the large-pitch fins and the small-pitch fins is slightly smaller than the inner diameter of the heating tube, which can form a water flow channel.

[0004] The above structure places the outer fins on the outside of the heating tube, and sets small-pitch fins and large-pitch fins inside the heating tube to achieve stable heating of the water flow. However, when using the whole system, the pipes still need to be installed. Usually, the pipes can be directly installed on the existing heating device, generally by bolt fixing or welding. When the mandrel inside the heating tube needs to be replaced or cleaned, the entire mandrel needs to be removed. Furthermore, the setting of small-pitch and large-pitch fins affects the quick disassembly of the mandrel, which makes it inconvenient for subsequent maintenance and cleaning of the heating tube. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a heating device. The technical problem to be solved by this utility model is: how to solve the problem of difficult maintenance and cleaning of heat pipes in existing heating devices after long-term use.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A heating device includes a tube body and a heat pipe for placing a heat transfer medium. The lower end of the tube body has a water inlet, and the upper end of the tube body has a water outlet. The device is characterized in that a plug-in part is detachably connected to the bottom of the tube body, the heat pipe is inserted into the plug-in part, and the heat pipe can be moved vertically out of the tube body along with the plug-in part. The upper end of the heat pipe is located inside the inner cavity of the tube body, and the lower end is located outside the inner cavity of the tube body.

[0008] The heat transfer fluid is placed at the lower end of the heat pipe. The flue gas generated by the external combustion equipment heats the lower end of the pipe. After heating, the heat transfer fluid vaporizes, and the resulting high-temperature gas flows to the upper end of the pipe. The water to be heated enters the pipe from the inlet at the lower end and is heated by the high-temperature gas inside the heat pipe. After the heat is released, the high-temperature gas liquefies and falls to the bottom of the heat pipe, thus achieving the reuse of the heat transfer fluid. The connection between the heat pipe and the pipe body is a detachable connector at the bottom of the pipe body. Therefore, if the heat pipe is damaged, the connector can be directly removed from the bottom of the pipe body, and the heat pipe is moved vertically out of the pipe body along with the connector, achieving quick disassembly. In order to meet different heating needs, the amount and temperature of the flue gas can be controlled, thereby maximizing the vaporization of heat transfer fluid and improving the heating effect.

[0009] The heat transfer medium can be lithium bromide and water. When heated, the water will vaporize into high-temperature water vapor, and the concentration of lithium bromide will increase. When the high-temperature water vapor condenses and drips to the bottom of the pipe after passing through the inlet and outlet pipes, the water returns to the lithium bromide solution, and the liquid concentration of the lithium bromide solution decreases.

[0010] In the heating device described above, the tube body includes a hollow cylindrical receiving part and a hemispherical upper sealing head. The upper end of the receiving part is fixedly connected to the lower end of the upper sealing head. The water outlet is located at the top of the upper sealing head, and the water inlet is located on the lower side wall of the receiving part.

[0011] The tube body adopts a split structure, which facilitates the installation of the heat pipe and allows for cleaning of the inside of the tube body without completely removing the heat pipe. The water outlet is located at the lower end of the upper sealing head, and the water inlet is located at the lower end of the receiving part, which ensures that the water entering the tube body is fully heated before being discharged, thus improving the heating stability of the heating equipment.

[0012] In the heating device described above, the plug-in part is block-shaped, the heat pipe is vertically inserted into the plug-in part, and the plug-in part is threadedly connected to the lower end of the receiving part.

[0013] The use of threaded connections is advantageous because it facilitates the processing and installation of the insertion and receiving parts, and also provides a better seal, improving the sealing performance of the heating equipment during normal use.

[0014] In the heating device described above, a plurality of heating fins are provided on the lower part of the heat pipe, and the plurality of heating fins are evenly distributed along the length of the heat pipe.

[0015] The heating fins enhance the heat absorption effect at the bottom of the heat pipe, which in turn facilitates the rapid vaporization of the heat transfer fluid and improves the heating efficiency of the heating equipment.

[0016] In the heating device described above, a drain outlet is provided on the lower end wall of the receiving part, and a plug is inserted into the drain outlet of the receiving part.

[0017] By providing a drain outlet on the lower end wall of the container, it is easy to discharge impurities from the water inside the container after long-term use. When in use, the drain outlet can be plugged with a plug to ensure normal operation.

[0018] In the heating device described above, the plug-in part has an elastic locking block, and the lower end of the receiving part has an annular locking ring. The plug-in part is connected to the receiving part by inserting the elastic locking block into the locking ring.

[0019] The combination of the elastic locking block on the plug and the locking ring on the receiving part enables quick disassembly and ensures stability during normal use.

[0020] Compared with existing technologies, this heating device has the following advantages: heating is achieved through high-temperature gas inside the heat pipe, and the high-temperature gas liquefies after the heat is released and falls to the bottom of the heat pipe, thus realizing the reuse of the heat transfer medium. The connection between the heat pipe and the pipe body is through a detachable connector at the bottom of the pipe body. Therefore, when the heat pipe is damaged, the connector can be directly removed from the bottom of the pipe body and the heat pipe is moved vertically out of the pipe body along with the connector, achieving rapid disassembly.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] Example 1

[0028] Specifically, such as Figure 1-3 As shown, the bottom of the tube body 1 is detachably connected to the insertion part 3, the heat pipe 2 is inserted into the insertion part 3, and the heat pipe 2 can be moved vertically out of the tube body 1 along with the insertion part 3. The upper end of the heat pipe 2 is located inside the inner cavity of the tube body 1, and the lower end is located outside the inner cavity of the tube body 1.

[0029] The heat transfer fluid is placed at the lower end of heat pipe 2. The flue gas generated by the external combustion equipment heats the lower end of pipe body 1. After being heated, the heat transfer fluid vaporizes, and the high-temperature gas generated flows to the upper end of pipe body 1. The water to be heated enters pipe body 1 from the water inlet 11a at the lower end of pipe body 1 and is heated by the high-temperature gas in heat pipe 2. After the high-temperature gas releases its heat, it liquefies and falls to the bottom of heat pipe 2, thus realizing the reuse of heat transfer fluid. The connection between heat pipe 2 and pipe body 1 is achieved by a detachable connector 3 at the bottom of pipe body 1. Therefore, when heat pipe 2 is damaged, connector 3 can be directly removed from the bottom of pipe body 1 and the housing can be removed. Heat pipe 2 moves vertically out of pipe body 1 along with connector 3, realizing quick disassembly. In order to meet different heating needs, the amount and temperature of flue gas can be controlled, thereby making more heat transfer fluid vaporize and improving the heating effect.

The upper end of the receiving part 11 is fixedly connected to the lower end of the upper sealing head 12. The water outlet 12a is opened at the top of the upper sealing head 12, the water inlet 11a is opened on the lower side wall of the receiving part 11, and the drain outlet 11b is opened on the lower end wall of the receiving part 11. A plug 4 is plugged at the drain outlet 11b of the receiving part 11.

[0031] like Figure 1 and Figure 3 As shown, multiple heating fins 21 are provided on the lower part of the heat pipe 2. The multiple heating fins 21 are evenly distributed along the length of the heat pipe 2. The plug part 3 is block-shaped. The heat pipe 2 is vertically plugged into the plug part 3. The plug part 3 is threadedly connected to the lower end of the receiving part 11.
