Description

Technical Field

[0001] This article belongs to the technical field of heat exchanger devices, and specifically relates to a heat exchanger device based on a surface anti-corrosion coating. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is often used in various industrial production places that require temperature control. Graphene is a highly corrosion-resistant coating with the characteristics of high heat transfer.

[0003] For different media, various anti-corrosion heat exchangers are increasingly widely used. Among them, water coolers made of carbon steel account for 50% of the total number of heat exchangers in various devices. When the circulating water in the water cooler exchanges heat with the medium with a higher temperature, it is very easy to cause scaling on the water side tube wall; when the circulating water flow rate is low and the water quality is poor, sludge will also accumulate on the tube wall. Scale and sludge not only increase the thermal resistance and reduce the heat exchange efficiency of the equipment, but also are very likely to cause corrosion and internal leakage during the operation of the water cooler. The outer wall of the heat exchange tube with an anti-corrosion coating has the effect of reducing scaling of the tube bundle and delaying corrosion and leakage of the heat exchanger.

[0004] However, the existing heat exchangers have defects in structure and construction process: the heat exchanger needs to be exposed to high temperature for a long time, which can easily lead to corrosion of the heat exchange tubes, resulting in overall scrapping and wasting resources; the size of the baffle holes and tube sheet holes, as well as the scratches on the coating during assembly or maintenance, cause the coating on the outer wall of the heat exchange tube to fall off, and after the scratches, it cannot be effectively repaired during equipment construction or operation; and due to process limitations, the end part of the heat exchange tube is not coated, affecting the overall corrosion resistance.

[0005] Therefore, there is a need for a heat exchanger with an anti-corrosion coating on the surface that can be easily maintained to achieve replacement or maintenance of the heat exchange tubes. Summary of the invention

[0006] In order to solve the above problems, this paper proposes a heat exchanger device based on a surface anti-corrosion coating, wherein a plurality of heat exchange tubes are horizontally arranged inside the heat exchanger device, the two ends of the heat exchange tubes are arranged inside the guide cavity, and the outer side of the middle part of the heat exchange tubes is arranged inside the heat exchange cavity. An outer shell is arranged on the outside of the heat exchanger device, and a plurality of partition plates are longitudinally arranged inside the outer shell. A sealing cover is arranged on the upper part of the outer shell, and a plurality of assembly grooves are arranged on the surface of the partition plates in parallel to each other, and a plurality of heat exchange tubes are arranged horizontally inside the assembly grooves of the plurality of partition plates. A guide cavity is arranged on the outside of the partition plates at the two ends of the outer shell, and a heat exchange cavity is arranged between the partition plates at the two ends of the outer shell, and the outer sides of the partition plates at the two ends of the heat exchange tubes are externally wrapped. A sealing hoop is provided, and the inner end face of the sealing hoop is sealingly connected to the assembly groove of the partition plate, a partition sealing plate is provided on the inner side of the assembly groove between the upper and lower sealing hoops, and a plurality of cover bottom sealing plug plates are longitudinally provided on the lower surface of the sealing cover, and the cover bottom sealing plug plates are aligned with the assembly groove of the partition plate and connected by snapping. By improving the heat exchange tube structure inside the heat exchanger that was originally welded in one piece to a combined assembled heat exchange tube, it is possible to achieve installation without penetrating plug-in type, thereby effectively protecting the coating on the outer surface of the heat exchange tube, and the assembly form can also facilitate the replacement of the heat exchange tube, which is not only convenient for the maintenance of the inside of the heat exchanger, but also can achieve the effect of replacement and renewal, thereby extending the service life of the heat exchanger.

[0007] The outer shell is in the shape of a transverse rectangular shell, and the interior of the outer shell is divided into a flow guide chamber and a heat exchange chamber by a partition plate. The two end surfaces of the outer shell are connected to the flow guide chamber and are provided with tube-side openings, and the front and rear side surfaces of the outer shell are connected to the heat exchange chamber and are provided with shell-side openings. The upper surface of the outer shell is provided with a sealing assembly opening, and the outer side of the sealing assembly opening is protruding with a sealing assembly edge. The outer shell is sealed and connected to the sealing cover through the sealing assembly edge. The outer shell with the sealing assembly opening is used to realize an open design of the entire outer shell, so that the installation of the heat exchange tube can be realized.

[0008] The sealing cover is in the shape of a rectangular cover, and the outer contour of the sealing cover is the same as the outer contour of the top surface of the outer shell body. The outer edge contour of the sealing cover is flange-type and is sealed and bolted to the outer shell body. The bottom surface of the sealing cover is longitudinally provided with a plurality of cover bottom sealing plug plates, and the separation sealing groove of the sealing cover corresponds to the assembly groove of each separation plate one by one. The cover bottom sealing plug plate is a rectangular slot rubber sealing plate, and both sides of the cover bottom sealing plug plate are provided with plug-in grooves. The top end of the cover bottom sealing plug plate is fixedly sealed and connected to the bottom surface of the sealing cover, and the bottom end of the cover bottom sealing plug plate is provided with an arc-shaped connecting sealing edge, and the connecting sealing edge is crimped and connected to the sealing hoop. The outer shell is completely sealed from the top through the sealing cover, thereby achieving effective sealing inside the shell and achieving the effect of heat exchange, and the cover bottom sealing plug plate is also used to perform downward pressure sealing from top to bottom, thereby sealing the last opening at the upper end of the assembly groove of the separation plate, and at the same time, the heat exchange tubes stacked below are pressed down and reinforced to ensure the installation strength.

[0009] The partition plate is in the shape of a rectangular plate, and the outer contour of the partition plate is the same as the internal longitudinal cross-sectional shape of the outer shell. A plurality of assembly grooves are vertically arranged on the surface of the partition plate, and the assembly grooves are upper conductive U-shaped grooves, and the width of the assembly grooves is the same as the diameter of the heat exchange tube. The partition plate not only realizes the separation of the integrated outer shell into two independent cavities, namely the guide cavity and the heat exchange cavity, but also realizes the lateral support of the heat exchange tube. During normal use of the heat exchanger, one side of the sealing cover faces the front, so that the middle partition plate is supported, and the gap between the assembly grooves of the middle partition plate can also realize the diversion of the liquid inside the heat exchange cavity, thereby realizing the heat exchange function of the heat exchanger.

[0010] The sealing hoop is a semicircular compression-fit hoop, and the rear end face of the sealing hoop is sealingly fitted to the surface of the assembly groove of the partition plate, and the upper and lower ends of the upper and lower adjacent sealing hoops are sealed with partition sealing plates, and the partition sealing plate is in the shape of a vertical slot-type sealing plate, and the upper and lower ends of the partition sealing plate are provided with arc-shaped connecting sealing edges, and the two ends of the partition sealing plate are connected to the rear end of the sealing hoop by crimping through the connecting sealing edges. By using the sealing hoop, not only the outer sides of the two ends of the heat exchange tube can be sealed, but also the basic support effect can be achieved, and the sealing hoop also cooperates with the partition sealing plate, so that the gap in the assembly groove between adjacent sealing hoops is filled and sealed, so that the guide cavity and the heat exchange cavity are absolutely sealed to achieve heat exchange operation.

[0011] Beneficial effects:

[0012] By improving the original one-piece welded heat exchanger internal heat exchanger structure into a combined assembled heat exchange tube, it is possible to achieve installation without plug-in installation, thereby effectively protecting the coating on the outer surface of the heat exchange tube, and the assembly form can also facilitate the replacement of the heat exchange tube, which not only facilitates the maintenance of the inside of the heat exchanger, but also can achieve the effect of replacement and renewal, thereby extending the service life of the heat exchanger.

[0013] The outer shell with the sealed assembly opening enables the entire outer shell to be designed to be open, thereby enabling the installation of the heat exchange tubes.

[0014] The outer shell is completely sealed from the top by the sealing cover, thereby achieving effective sealing inside the shell and heat exchange effect, and the bottom sealing plug plate of the cover is used to perform downward pressure sealing from top to bottom, thereby sealing the last opening at the upper end of the assembly groove of the partition plate, and at the same time, the heat exchange tubes stacked below are pressed down and reinforced to ensure the installation strength.

[0015] The partition plate not only separates the integrated outer shell into two independent cavities, the guide cavity and the heat exchange cavity, but also supports the heat exchange tubes laterally. During normal use of the heat exchanger, the sealing cover faces the front, thereby providing support for the middle partition plate. The gap between the assembly grooves of the middle partition plate can also guide the liquid inside the heat exchange cavity, thereby realizing the heat exchange function of the heat exchanger.

[0016] By using the sealing clamp, not only can the outer sides of both ends of the heat exchange tube be sealed, but also it can play the role of basic support. In addition, the sealing clamp cooperates with the partition sealing plate to fill and seal the assembly groove gap between adjacent sealing clamps, so that the guide cavity and the heat exchange cavity are absolutely sealed to realize the heat exchange operation.
