Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, and in particular to a heat exchanger and a heat exchange method based on a filter residue cleaning structure. Background Art

[0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid. It is also called heat exchanger. It is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a higher temperature fluid to a lower temperature fluid so that the fluid temperature reaches the specified index of the process to meet the needs of process conditions. It is also one of the main equipment for improving energy utilization.

[0003] In traditional heat exchangers, they are placed in a vertical square shape, occupying a large area and wasting space. This is not conducive to the laying and addition of production lines. Moreover, after long-term use, the alkaline residue generated inside the vertical heat exchanger adheres to the inner wall of the exchange pipe, which is not easy to clean. At the same time, the fallen alkaline residue is concentrated at the bottom of the exchange pipe, which will cause the blockage of the fluid discharge pipe and affect the heat exchange process. On the other hand, when the heat exchange volume is small, it cannot fill the exchange pipe, that is, it cannot fully contact with the transferred fluid, which reduces the heat exchange efficiency. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the present invention provides a heat exchanger and a heat exchange method based on a filter residue cleaning structure, which is provided with a heat exchange medium component in a heat exchange mechanism for conveying heat exchange medium at one end, and at the same time conveying the heating medium to be heated to the inside of a heat exchange tank from one end of a heating medium circulation component, wherein the medium to be heated is introduced into the heat exchange tank through a heating medium liquid inlet provided on one side above the heat exchange tank, and at the same time, heat exchange medium converging ports provided at both ends of the heat exchange tank converge the heat exchange medium, and pass through the heat exchange tank to heat the medium to be heated inside the heat exchange tank, and then the heating medium liquid outlet provided on the lower side of the heat exchange tank is used to heat the medium to be heated. The heated heating medium is discharged from the outlet to complete the heat exchange process. A large amount of alkaline slag will be generated during the heat exchange process. The alkaline slag filtering mechanism arranged at the bottom of the heat exchange tank will filter out the alkaline slag centrally to ensure the cleanliness of the inside of the heat exchange tank. It solves the problem that the alkaline slag generated on the inner wall of the exchange pipe adheres to the inner wall of the exchange pipe and is not easy to clean. At the same time, the alkaline slag that falls off is concentrated at the bottom of the exchange pipe, which will cause blockage of the fluid discharge pipe and affect the heat exchange process. On the other hand, when the heat exchange fluid is less, it cannot fill the exchange pipe, that is, it cannot fully contact with the transferred fluid, resulting in reduced heat exchange efficiency.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a heat exchanger based on a filter residue cleaning structure, which has the following beneficial effects:

[0019] 1. The heat exchanger based on the filter residue cleaning structure transports the heat exchange medium through one end of the heat exchange medium component in the heat exchange mechanism, and at the same time transports the heating medium to be heated to the inside of the heat exchange tank from one end of the heating medium circulation component, wherein the medium to be heated is introduced into the heat exchange tank through the heating medium liquid inlet arranged on the upper side of the heat exchange tank, and at the same time, the heat exchange medium is gathered at the heat exchange medium converging ports arranged at both ends of the heat exchange tank, and the heat exchange medium is heated by passing through the heat exchange tank, and then the heated heating medium is discharged from the heating medium liquid outlet arranged on the lower side of the heat exchange tank to complete the heat exchange treatment. A large amount of alkali slag will be generated during the heat exchange process, and the alkali slag will be centrally filtered out by the alkali slag filtering mechanism arranged at the bottom of the heat exchange tank to ensure the cleanliness of the inside of the heat exchange tank.

[0020] 2. The heat exchanger based on the filter residue cleaning structure can, through a horizontal support frame, stack multiple groups of heat exchangers. When the amount of heat exchange medium reaches a certain level, a circulating heat exchange processing module can be formed to reduce the floor space. On the other hand, when the amount of heat exchange medium is very small and a circulating heat exchange processing module cannot be formed, the heat exchanger at the bottom is used, and the heat exchange medium can also be processed in the heat exchanger at the bottom with a spirally arranged grid plate.

[0021] 3. The heat exchanger based on the filter residue cleaning structure is provided with a filter residue inlet pipe with a larger inner diameter above the filter residue discharge pipe. When the filter plate and the pressure plate are located at the position of the filter residue inlet pipe, the alkaline residue transported by the grid plate enters into the filter residue discharge pipe through the space between the filter plate and the filter residue inlet pipe. At this time, the filter residue collecting component at the bottom of the filter residue discharge pipe is in a closed state, and the filter residue cannot be discharged; when the linkage mechanism drives the pressure plate to move downward, the pressure plate drives the filter plate to descend together, squeezes the alkaline residue in the filter residue discharge pipe, and the heating medium in the filter residue discharge pipe is discharged from the filter press hole at the bottom of the filter press cylinder and enters the inside of the heat exchange tank to reduce heat loss.

[0022] 4. The heat exchanger based on the filter residue cleaning structure rotates under the drive of the rotating grid plate. During the conversion process of the elliptical driving plate from the narrower end contacting the push plate to the wider end contacting the push plate, the elliptical driving plate gradually presses the pressure plate downward. Since a compression spring is arranged between the pressure plate and the sealing plate, the pressure plate drives the filter cartridge and the filter plate to move downward together through the compression spring. At this time, under the action of the compression spring, the pressure plate is located above the filter press hole. When the filter plate moves downward, the alkali residue is squeezed, and the heating medium in the alkali residue is filtered through the filter press hole and enters the heat exchange tank. As the alkali residue is continuously squeezed, after the filter plate drops to the maximum extent, the pressure plate begins to approach the filter plate until the pressure plate passes over the filter press hole and continues to move downward with the filter plate. The blocking block in the filter residue collecting assembly pushes the blocking block downward as the pressure plate and the filter plate are continuously pressed downward. The blocking block compresses the supporting spring until the blocking block leaves the bottom of the filter residue discharge pipe, and the squeezed alkali residue in the filter residue discharge pipe falls into the collection box for collection.

[0046] When the heating medium circulation component 3 rotates, the spirally arranged grid plate 31 inside the heat exchange tank 5 rotates inside the heat exchange tank 5, and the heated medium just inputted inside is transported forward while rolling, thereby increasing the contact with the heat exchange medium component 2, thereby avoiding the phenomenon that the heat exchange effect is poor due to too little heated medium inside the heat exchange tank 5 at the beginning of the heat exchange process; wherein the scraper plate 32 in the heating medium circulation component 3 is driven to rotate along the inner wall of the heat exchange tank 5 when the grid plate 31 rotates, so as to scrape off the alkali residue on the inner wall of the heat exchange tank 5, and the spirally arranged grid plate 31 transports the alkali residue forward in a rotating state until it is transported to the position of the alkali residue filtering mechanism 6 and is filtered out;

[0047] At the same time, the filter plate 61 and the pressing plate 62 in the alkali residue filtering mechanism 6, when the heating medium circulation component 3 rotates, drive the pressing plate 62 to move downward through the linkage mechanism 7, and during the downward movement of the pressing plate 62, drive the filter plate 61 to move downward, and the grid plate 31 conducts the alkali residue to be filtered, and the alkali residue is discharged into the residue collecting component 57 through the residue discharge pipe 55 for collection after filtering;

[0048] In the above process, a filter residue inlet pipe 56 with a larger inner diameter is arranged above the filter residue discharge pipe 55. When the filter plate 61 and the pressure plate 62 are located at the position of the filter residue inlet pipe 56, the alkaline residue transported by the grid plate 31 enters the filter residue discharge pipe 55 through the space between the filter plate 61 and the filter residue inlet pipe 56. At this time, the filter residue collecting assembly 57 at the bottom of the filter residue discharge pipe 55 is in a closed state, and the filter residue cannot be discharged; when the linkage mechanism 7 drives the pressure plate 62 to move downward, the pressure plate 62 drives the filter plate 61 to descend together, and the alkaline residue in the filter residue discharge pipe 55 is squeezed. The heating medium in the filter residue discharge pipe 55 is discharged from the filter pressure hole 64 at the bottom of the filter pressure cylinder 63 and enters the interior of the heat exchange tank 5 to reduce heat loss;

[0049] The elliptical driving plate 71 in the linkage mechanism 7 is driven by the rotating grid plate 31 to rotate. In the process of the elliptical driving plate 71 contacting the push plate 622 from the narrow end to the wider end, the elliptical driving plate 71 gradually presses the pressing plate 62 downward. Since a compression spring 623 is provided between the pressing plate 62 and the sealing plate 631, the pressing plate 62 drives the filter cartridge 63 and the filter plate 61 to move downward together through the compression spring 623. At this time, under the action of the compression spring 623, the pressing plate 62 is located above the filter hole 64. When the filter plate 61 moves downward, the alkali residue is squeezed, and the alkali residue in the alkali residue is The heating medium is filtered through the filter press hole 64 and enters the heat exchange tank 5. As the alkali residue is continuously squeezed, the filter plate 61 drops to the maximum extent, and the pressure plate 62 begins to approach the filter plate 61 until the pressure plate 62 passes over the filter press hole 64 and continues to move downward in cooperation with the filter plate 61. The sealing block 572 in the residue collecting assembly 57 is pushed downward as the pressure plate 62 and the filter plate 61 continue to press downward, and the sealing block 572 compresses the supporting spring 573 until the sealing block 572 leaves the bottom of the residue discharge pipe 55, and the squeezed alkali residue in the residue discharge pipe 55 falls into the collecting box 571 for collection.
