Description

Technical Field

[0001] The invention relates to the technical field of plate heat exchangers, in particular to an anti-corrosion and high-efficiency plate heat exchanger for geothermal use. Background Art

[0002] The geothermal plate heat exchanger is a key equipment in the geothermal energy development and utilization system. It is mainly used for heat exchange between geothermal water and circulating working fluid (such as water or antifreeze) to achieve efficient conversion and utilization of geothermal energy. The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal equipment for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and light structure, small footprint, wide application and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, and the footprint is one-third of that of the tube heat exchanger. The heat recovery rate can be as high as 90% or more.

[0003] However, the existing plate heat exchangers often have some problems in actual use: first, during the use of the existing plate heat exchangers, when reassembling the plate stack, the clamping device needs to be tightened. During the tightening process, over-tightening may cause the steel plate to break, which will damage the corrugated plate, resulting in loss of heat exchange efficiency and affecting normal use. At the same time, the gasket may be squeezed out. If the gasket is squeezed out, the plates will no longer be sealed, which may cause high-temperature and low-temperature liquids to mix, causing the outer shell metal of the plate heat exchanger to become brittle and easily burst under water pressure shock, causing personal injury and economic losses. Secondly, scale is easily generated inside the heat conduction plate during use. When cleaning, the heat conduction plate needs to be disassembled and cleaned, which is difficult to clean and the process is cumbersome. Summary of the invention

The first spring 34 pops out after contacting the pressure, and pushes the connecting plate 15 out to fit the limiting card slot 13, thereby improving the limiting ability and preventing excessive pressure after sliding, which affects the heat conducting component 32 and affects the use.

[0032] Among them, the cleaning component includes a mounting block 16, a hydraulic push rod 17, a rotating and retracting shell 18, and a support rod 35.

The limiting ring 21 is fixedly connected to the rotating and shrinking shell 18. The wire 22 is arranged on the top of the limiting ring 21. The wire 22 is fixedly connected to the rotating and shrinking shell 18. The wire 22 is wound around the outside of the rotating column 19, and the outermost end of the winding is in contact with the outer surface of the limiting ring 21. When it is necessary to clean the heat-conducting component 32, the hydraulic push rod 17 is started, and the hydraulic push rod 17 is started to drive the support rod 35 to move forward. The first connecting shaft 25 moves back and forth, and the support rod 35 moves back and forth, driving the first connecting shaft 25 to move back and forth. When the first connecting shaft 25 moves downward, since the second wire wheel 24 is fixedly connected at one end, the downward movement of the second wire wheel 24 will pull the wire 22, and the extension of the wire 22 will synchronously drive the first wire wheel 23 to rotate. The rotation of the first wire wheel 23 drives the first connecting shaft 25 to rotate. The rotation of the first connecting shaft 25 drives the toggle block 26 to rotate. The rotation of the toggle block 26 drives the swing block 28 to swing. The swing of the swing block 28 drives the high-pressure nozzle 29 to swing. The swing of the high-pressure nozzle 29 cleans the scale generated inside the heat conduction plate, avoiding the disassembly and cleaning of the heat conduction plate during cleaning, greatly reducing the difficulty of cleaning, and improving work efficiency.

[0034] Among them, the swing assembly includes a first wire wheel 23, a second wire wheel 24, a first connecting shaft 25 and a toggle block 26. The first wire wheel 23 is fixedly connected to the inside of the support rod 35, and the second wire wheel 24 is fixedly connected to the inside of the mounting block 16.

The first connecting shaft 25 is fixedly connected to one end of the first wire wheel 23, and the toggle block 26 is fixedly connected to the other end of the first connecting shaft 25. The movement of the support rod 35 drives the wire 22 to stretch, thereby driving the first wire wheel 23 to rotate, completing the motion conversion, so that it can increase the cleaning area and cleaning angle during use, greatly increase its applicability, and also improve the cleaning effect.

[0035] Among them, the swing assembly also includes a second connecting shaft 27, a swing block 28 and a high-pressure nozzle 29. The second connecting shaft 27 is fixedly connected to the inside of the support rod 35. The second connecting shaft 27 is arranged at the lower end of the first wire wheel 23. The middle part of the second connecting shaft 27 is rotatably connected with the swing block 28. One end of the swing block 28 is fixedly connected with the high-pressure nozzle 29. By rotating the toggle block 26, the swing block 28 moves along the outer surface of the toggle block 26, so that the high-pressure nozzle 29 can swing to lift the cleaning angle.

[0036] Among them, there are two high-temperature water inlets 30 on one side of the fixed pressing plate 2, and two low-temperature water inlets 31 are set on the other side of the fixed pressing plate 2. The water inlets are the same on the same side, which can increase the circulating water pressure and make the water circulation channel longer, thereby improving the heat exchange efficiency of the plate heat exchanger during operation.

[0037] Among them, a heat-conducting component 32 is slidably connected between the positioning guide rod 3 and the lower guide rod 5. The heat-conducting component 32 is arranged between the fixed clamping plate 2 and the movable clamping plate 201. The top and bottom of the heat-conducting component 32 are provided with card grooves that cooperate with the positioning guide rod 3 and the lower guide rod 5.

[0038] Among them, the heat conducting component 32 includes multiple groups of right-opening heat conducting plates 3201, double-opening heat conducting plates 3202 and multiple groups of left-opening heat conducting plates 3203.

The right-opening heat conducting plates 3201 and the left-opening heat conducting plates 3203 are arranged alternately. The staggered arrangement enables high-temperature liquid and low-temperature liquid to perform staggered heat transfer, thereby increasing their contact heat transfer area and thus improving the heat transfer efficiency.

[0039] Among them, fish scale corrugations are arranged inside the right opening heat conducting plate 3201 and the double opening heat conducting plate 3202, and sealing rubber rings are arranged at the slots of the heat conducting component 32. The fish scale corrugations accelerate the flow rate and enable the right opening heat conducting plate 3201 and the double opening heat conducting plate 3202 to fit more closely, thereby further improving work efficiency.

The rotation of multiple pulleys 10 drives multiple rotating shafts 9 to rotate. The rotation of multiple rotating shafts 9 drives the sliding card plate 12 to slide inside the limiting rod 11. The sliding card plate 12 slides and pushes the movable clamping plate 201 inward to push and clamp the heat-conducting component 32. Before clamping, the required clamping force of the heat-conducting component 32 can be determined by the number of heat-conducting components 32. Then, by pressing the connecting plate 15, the connecting plate 15 is attached to the limiting card plate 14. At this time, the first spring 34 is compressed, and then the limiting card plate 14 is placed in the limiting Inside the slot 13, the first spring 34 pops out after contacting the pressure, and pushes the connecting plate 15 out to fit with the limit slot 13, thereby improving the limit capacity, preventing excessive pressure after sliding, and affecting the heat-conducting component 32, thereby preventing the sliding card plate 12 from over-pressing the heat-conducting component 32 during movement, thereby preventing excessive tightening from causing the steel plate to break, damaging the corrugated plate, causing the loss of heat exchange efficiency, affecting normal use, and at the same time preventing the gasket from being squeezed out, preventing the heat-conducting plate from no longer being sealed, causing the high-temperature and low-temperature liquids to mix, thereby causing the metal shell of the plate heat exchanger to become brittle and easily burst under the impact of water pressure, causing personal injury and economic losses;

[0042] When the heat conducting component 32 needs to be cleaned, the hydraulic push rod 17 is started, and the hydraulic push rod 17 is started to drive the support rod 35 to move back and forth. The reciprocating movement of the support rod 35 drives the first connecting shaft 25 to move back and forth. When the first connecting shaft 25 moves downward, since the second wire wheel 24 is fixedly connected at one end, the downward movement of the second wire wheel 24 will pull the wire 22, and the extension of the wire 22 will synchronously drive the first wire wheel 23 to rotate. The rotation of the first wire wheel 23 drives the first connecting shaft 25 to rotate. The rotation of the first connecting shaft 25 drives the toggle block 26 to rotate. The rotation of the toggle block 26 drives the swing block 28 to swing. The swing of the swing block 28 drives the high-pressure nozzle 29 to swing. The high-pressure nozzle 29 swings to clean the scale generated inside the heat conducting plate, avoiding the disassembly and cleaning of the heat conducting plate during cleaning, greatly reducing the difficulty of cleaning, and improving work efficiency.
