Description

Technical Field

[0001] The invention relates to the technical field of energy recovery, and in particular to an oil-free gas-liquid two-phase suspension centrifugal energy recovery machine. Background Art

[0002] Energy recovery technology refers to the collection, conversion and reuse of waste heat, excess pressure and other energies generated in industrial production processes through specific equipment and processes, in order to improve energy efficiency, reduce energy waste and reduce environmental pollution. In today's global energy shortage and increasingly stringent environmental protection requirements, energy recovery technology has become one of the important means to achieve energy conservation and emission reduction and promote industrial green transformation. Common energy recovery methods include industrial waste heat recovery, excess pressure recovery, energy recovery in waste gas treatment, etc. Among them, industrial waste heat recovery technology mainly focuses on the effective utilization of large amounts of waste heat generated by high-energy-consuming industries such as cement, steel, and oil refining, and converts waste heat into reusable heat or electrical energy through heat exchange, heat pump and other technologies. As a key pillar of energy conservation and emission reduction, industrial waste heat recovery technology is facing unprecedented development opportunities driven by global energy shortages and environmental protection policies. Among them, oil-free gas-liquid suspension technology has attracted much attention for its outstanding characteristics of high efficiency and energy saving. Its core advantages include oil-free lubrication, rapid heat transfer, and low maintenance costs. It perfectly meets the needs of high-energy-consuming industries such as cement, steel, and oil refining, especially in scenarios with strict environmental protection requirements. The oil-free equipment market has broad prospects and is becoming an important force in promoting industrial green transformation.

[0003] The current oil-free gas-liquid two-phase suspended centrifugal energy recovery machine generally passes through a desulfurization tower to allow the flue gas to enter the heat exchange device for heat exchange treatment, and then transfers the water source in the heat exchange to the oil-free gas-liquid two-phase suspended centrifugal unit, and then uses an oil-free gas-liquid two-phase suspended compressor to increase the temperature of the water source entering, and then transports the high-temperature water to the heating equipment, thereby completing the energy recovery operation. However, the heat exchange devices in the current energy recovery machines are mostly single-function and can only perform heat exchange operations, and are unable to process pollutants such as dust and acidic gases in the flue gas. At the same time, the heat exchange area is small, resulting in low heat exchange efficiency. Summary of the invention

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: 1. In the present invention, multiple groups of first U-shaped heat exchange tubes and second U-shaped heat exchange tubes are arranged in a staggered and dense manner, such that the high-temperature flue gas will sequentially contact multiple groups of first U-shaped heat exchange tubes and second U-shaped heat exchange tubes, and then efficiently cool the flue gas, thereby improving the heat exchange efficiency. At the same time, the first U-shaped heat exchange tubes and the second U-shaped heat exchange tubes are made of polyvinylidene fluoride anti-corrosion material, which can adapt to high-temperature, high-humidity and corrosive environments. Moreover, when heat exchanging, a water film can be formed on the outer surfaces of the first U-shaped heat exchange tubes and the second U-shaped heat exchange tubes to adsorb pollutants such as dust and acidic gases in the flue gas, realizing efficient heat exchange while performing dust removal operation on the flue gas.

[0018] 2. By starting the second motor and two groups of first motors in the present invention, the second threaded rod and two groups of first threaded rods can be driven to rotate, and then the third connecting plate and the first connecting plate can move downward on the surfaces of the second threaded rod and the first threaded rod respectively, enabling multiple groups of second nozzles and first nozzles to move up and down along the outer shapes of the first U-shaped heat exchange tubes and the second U-shaped heat exchange tubes to perform spray washing on their surfaces, thereby cleaning the surfaces of the first U-shaped heat exchange tubes and the second U-shaped heat exchange tubes more thoroughly.

[0019] 3. The two filter bottom plates of the present invention are arranged obliquely. When dust particles, SO, HSO, (SO) aerosol, HCl and other acidic gases in the flue gas flow through the first U-shaped heat exchange tubes and the second U-shaped heat exchange tubes, they can fully contact, adhere to and adsorb with the water film on the outer surfaces of the first U-shaped heat exchange tubes and the second U-shaped heat exchange tubes, and then condense and drain onto the filter bottom plates together with the condensate for filtration operation. The filtered water source is stored in the water storage tank again, facilitating subsequent spray washing operation on the first U-shaped heat exchange tubes and the second U-shaped heat exchange tubes, thereby achieving the purpose of energy saving and water saving. At the same time, the impurities filtered out can be centrally stored in the collection box, which is convenient for the operator to clean regularly.

[0020] 4. By starting the third motor to drive the reciprocating screw rod to rotate in the present invention, the particulate impurities accumulated above the heat exchanger body can be actively swept and pushed to one side close to the communication port, and then fall into the collection box for storage, effectively preventing the filter bottom plate from being blocked when there are too many particulate impurities and they cannot slide down by their own gravity, thereby ensuring the filtering effect of the filter bottom plate.

A heat exchange component 2 is arranged in the inner cavity of the heat exchanger body 1, a cleaning component 3 is arranged in the inner cavity of the heat exchanger body 1, and a treatment component 4 is arranged in the inner cavity of the treatment chamber 11; The heat exchange component 2 includes multiple groups of first U-shaped heat exchange tubes 21 arranged in the inner cavity of the heat exchanger body 1, and both ends of the first U-shaped heat exchange tubes 21 extend to the top of the heat exchanger body 1. Multiple groups of second U-shaped heat exchange tubes 22 are arranged in the inner cavity of the heat exchanger body 1, and both ends of the second U-shaped heat exchange tubes 22 extend to the top of the heat exchanger body 1. The first U-shaped heat exchange tubes 21 and the second U-shaped heat exchange tubes 22 are made of polyvinylidene fluoride anti-corrosion material. The second U-shaped heat exchange tubes 22 are located inside the first U-shaped heat exchange tubes 21, and multiple groups of first U-shaped heat exchange tubes 21 and multiple groups of second U-shaped heat exchange tubes 22 are arranged in an interleaved manner. Two groups of communication chambers 23 are arranged above the heat exchanger body 1, and the two groups of communication chambers 23 are respectively connected to both ends of multiple groups of first U-shaped heat exchange tubes 21 and second U-shaped heat exchange tubes 22, and a connection port 24 is connected to the top of the communication chamber 23. The connection port 24 closer to the air inlet 13 is the liquid outlet, and the connection port 24 closer to the exhaust port 14 is the liquid inlet.

[0039] At one end of the top of the base plate 15 away from the heat exchanger body 1, there is an oil-free gas-liquid two-phase suspended centrifugal unit 16. An oil-free gas-liquid two-phase suspended compressor 17 is arranged on the oil-free gas-liquid two-phase suspended centrifugal unit 16. A desulfurization tower 18 is arranged on one side of the top of the base plate 15. A chimney 19 is arranged on the other side of the top of the base plate 15. A first flue gas pipe 10 is connected to one end of the air inlet 13, and the other end of the first flue gas pipe 10 is connected to the output end of the desulfurization tower 18. A second flue gas pipe 102 is connected to one end of the exhaust port 14, and the other end of the second flue gas pipe 102 is communicated with the chimney 19. A first diversion pipe 101 is connected to the connection port 24 at the top of a group of communication bins 23, and one end of the first diversion pipe 101 is connected to the input end of the oil-free gas-liquid two-phase suspended centrifugal unit 16.

One group of connection ports 24 is connected to an external water supply device through the second diversion pipe 103, and the other group of connection ports 24 is connected to the oil-free gas-liquid two-phase suspended centrifugal unit 16 through the first diversion pipe 101. At the same time, the output end of the oil-free gas-liquid two-phase suspended centrifugal unit 16 is connected to an external heating device. Then, after the flue gas is desulfurized by the desulfurization tower 18, the flue gas enters the inner cavity of the heat exchanger body 1 through the first flue gas pipe 10 and the air inlet 13. The multi-group first U-shaped heat exchange tubes 21 and the second U-shaped heat exchange tubes 22 are arranged in a staggered manner. Then, the high-temperature flue gas will sequentially contact the multi-group first U-shaped heat exchange tubes 21 and the second U-shaped heat exchange tubes 22, and then the temperature of the flue gas is efficiently reduced. After that, the flue gas is discharged from the exhaust port 14 of the inner cavity of the heat exchanger body 1 and is transferred to the chimney 19 through the second flue gas pipe 102 and discharged. And the water source that has undergone heat exchange in the multi-group first U-shaped heat exchange tubes 21 and the second U-shaped heat exchange tubes 22 will be transferred to the oil-free gas-liquid two-phase suspended centrifugal unit 16 through the first diversion pipe 101, then processed by the oil-free gas-liquid two-phase suspended compressor 17, and finally transferred to an external heating device for heating use. At the same time, when the flue gas contacts the multi-group first U-shaped heat exchange tubes 21 and the second U-shaped heat exchange tubes 22 and the temperature is reduced, a large amount of water vapor condenses into a water film on the outer surfaces of the first U-shaped heat exchange tubes 21 and the second U-shaped heat exchange tubes 22. When acidic gases such as dust particles, SO2, H2SO4, SO3 aerosol, and HCl in the flue gas flow through the first U-shaped heat exchange tubes 21 and the second U-shaped heat exchange tubes 22, they fully contact, adhere to, and adsorb to the water film on the outer surfaces of the first U-shaped heat exchange tubes 21 and the second U-shaped heat exchange tubes 22 and are discharged together with the condensate to the bottom of the heat exchanger body 1.

[0047] During the use process, by starting the second motor 3291 and the two groups of first motors 3101, the second threaded rod 3292 and the two groups of first threaded rods 3102 can be driven to rotate, and then the third connecting plate 325 and the first connecting plate 316 can move downward on the surfaces of the second threaded rod 3292 and the first threaded rod 3102 respectively. When the third connecting plate 325 moves downward, it will drive the two groups of third sliders 323 to move downward in the inner cavity of the third chute 321, and then drive the second outer sleeve rod 3294 and the second inner sleeve rod 3295 sleeved in the limiting sleeve 3293 on the third connecting plate 325 to move downward, and then drive the fourth connecting plate 326 to move downward synchronously, so that the fourth slider 324 slides and moves downward inside the U-shaped chute 322, and then the second main water pipe 327 on the fourth connecting plate 326 moves downward. When the fourth connecting plate 326 moves to the bottom end of the U-shaped chute 322, since the bottom end of the U-shaped chute 322 begins to narrow, the two groups of fourth sliders 324 on the U-shaped chute 322 will move closer to each other, and then the second inner sleeve rod 3295 will retract into the inner cavity of the second outer sleeve rod 3294, and at the same time, the second spring 3296 will contract, and then the two groups of fourth connecting plates 326 will move closer to each other and move downward, so that the second main water pipe 327 can adapt to the narrower bottom of the second U-shaped heat exchange pipe 22 and the first U-shaped heat exchange pipe 21.

When the second slider 315 on the second connecting plate 317 moves to the bottom end of the second chute 312 and continues to move, it will enter the inner side of the arc-shaped chute 313. Then, under the guidance of the arc-shaped chute 313, it can drive the second connecting plate 317 to gradually move away from the first connecting plate 316, and at the same time, the first spring 3105 will be stretched. At this time, the first spray head 319 on the first main water pipe 318 will gradually approach the bottom arc position of the first U-shaped heat exchange pipe 21; When the second motor 3291 and the two groups of first motors 3101 are started to drive the two groups of second main water pipes 327 and the first main water pipe 318 to move downward, the water pump 333 is started synchronously. Then, the water pump 333 can be used to extract the water source in the water storage tank 12, and then transfer it to the connecting rigid straight pipe 335 through the connecting hose 336. Then, it is respectively conveyed into the inner cavities of the two groups of second main water pipes 327 through the first connecting pipe 331. Then, through the two groups of second connecting pipes 332, the water sources in the two groups of second main water pipes 327 can be respectively conveyed into the inner cavities of the two groups of first main water pipes 318. Then, when the two groups of second main water pipes 327 and the first main water pipe 318 move downward, the water source can be sprayed through the second spray heads 328 and the first spray heads 319 to spray and wash the surfaces of the first U-shaped heat exchange pipe 21 and the second U-shaped heat exchange pipe 22, and achieve the purpose of purification and dust removal. Then, the water source after washing will fall together to the bottom of the inner cavity of the heat exchanger body 1; When the two groups of second main water pipes 327 and the first main water pipe 318 move downward, they can drive the connecting rigid straight pipe 335 to move downward, and the bottom end of the connecting rigid straight pipe 335 is inside the positioning sleeve 334 and slides downward, and then the connecting hose 336 is removed from the inner cavity of the positioning sleeve 334.

[0048] The remaining structure is the same as that of Embodiment 1.

[0049] Embodiment 3 Refer to Figures 1-12, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the processing component 4 includes a filtering component 41 disposed in the inner cavity of the processing chamber 11 and a cleaning component 42 disposed on the filtering component 41. The filtering component 41 includes two groups of communication ports 413 opened on one side of the processing chamber 11, and the communication ports 413 communicate with the inner cavity of the processing chamber 11. Two groups of filtering bottom plates 411 are installed on one side of the inner cavity of the processing chamber 11, and one ends of the two groups of filtering bottom plates 411 extend to the outside of the heat exchanger body 1 through the two groups of communication ports 413 respectively. The filtering bottom plates 411 are inclined to facilitate the automatic sliding of the impurities filtered on the top of the filtering bottom plates 411 due to gravity. Blocking side plates 412 are fixedly installed at both ends of the top of the filtering bottom plates 411 to facilitate blocking the impurities and prevent them from falling from both ends of the filtering bottom plates 411. A collection box 415 is fixedly installed at the bottom of one side of the processing chamber 11, and a guiding triangular plate 414 is fixedly installed on one side of the heat exchanger body 1, and the guiding triangular plate 414 is located between the two groups of communication ports 413. Through the setting of the guiding triangular plate 414, it is avoided that the impurities falling from one side of the upper filtering bottom plate 411 fall onto the lower filtering bottom plate 411, and the impurities on one side of the upper filtering bottom plate 411 directly fall into the collection box 415 for storage.

[0050] The cleaning component 42 includes a reciprocating lead screw 421 rotatably connected to both sides of the inner cavity of the processing chamber 11 and located below the filtering bottom plate 411, and one end of the reciprocating lead screw 421 extends to the outside of the processing chamber 11. The reciprocating lead screw 421 is inclined and parallel to the filtering bottom plate 411. A third motor 428 is fixedly installed on one side of the processing chamber 11, and the output end of the third motor 428 is connected to one end of the reciprocating lead screw 421 located outside the heat exchanger body 1. An internal thread sleeve block 422 is threadedly sleeved on the surface of the reciprocating lead screw 421. L-shaped connecting plates 423 are fixedly installed at both ends of the internal thread sleeve block 422. Slide rails 425 are opened at the ends of the two groups of blocking side plates 412 close to each other at both ends of the filtering bottom plate 411. A scraper 424 is slidably connected above the filtering bottom plate 411. Limit slider blocks 426 are fixedly installed at both ends of the scraper 424, and the limit slider blocks 426 are slidably connected to the inner cavity of the slide rails 425. And connecting blocks 427 are fixedly installed at the tops of both ends of the scraper 424, and the connecting blocks 427 are connected to the surfaces of the L-shaped connecting plates 423.

[0051] During use, when acidic gases such as dust particles, SO2, H2SO4, SO3 aerosol, and HCl in the flue gas flow through the first U-shaped heat exchange tube 21 and the second U-shaped heat exchange tube 22, they fully contact, adhere to, and adsorb with the water film on the outer surfaces of the first U-shaped heat exchange tube 21 and the second U-shaped heat exchange tube 22. When they condense and drain into the bottom of the heat exchanger body 1 together with the condensate, they will fall onto a set of filter bottom plates 411 in the inner cavity of the treatment bin 11. Then, the particulate impurities are filtered above the set of filter bottom plates 411, while the liquid falls onto another set of filter bottom plates 411. Then, the other set of filter bottom plates 411 filters the particulate impurities on its filter bottom plate 411 again, and the liquid is filtered again and falls into the water storage tank 12 for storage, facilitating subsequent use operations. At the same time, by using the inclined setting of the filter bottom plates 411, the particulate impurities filtered above the filter bottom plates 411 can slide towards the side of the communication port 413 and finally slide into the collection box 415 for centralized storage and treatment; When there is too much particulate impurity accumulated above the filter bottom plate 411, the third motor 428 is started to drive the reciprocating lead screw 421 to rotate. Then, the internally threaded sleeve block 422 can be driven to move on the surface of the reciprocating lead screw 421, and then the L-shaped connecting plate 423 drives the two scraper plates 424 to move above the filter bottom plate 411. At the same time, the limit slider 426 slides inside the slide rail 425, and then the particulate impurities accumulated above the heat exchanger body 1 can be actively swept and pushed to the side close to the communication port 413 and then fall into the collection box 415 for storage.

[0052] The remaining structure is the same as that of Embodiment 2.
