[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other.
[0024] See also Figure 1-Figure 4 .
[0025] The utility model discloses a steam recovery device, comprising:
[0026] A conveying component 1, a heat exchange component 2 is provided on one side of the conveying component 1, and the heat exchange component 2 is used to receive steam transported from the outside. The conveying component 1 transports the heat exchange medium to the heat exchange component 2 through the infusion pipe 13 to perform heat exchange with the steam;
[0027] The cleaning component 3 includes a reciprocating screw 31 disposed in the heat exchange component 2, and one end of the reciprocating screw 31 extends out of the heat exchange component 2 and extends into the infusion tube 13, and is sealed with the tube wall of the infusion tube 13. The end of the reciprocating screw 31 located in the infusion tube 13 is provided with an impeller 32, and the impeller 32 can drive the reciprocating screw 31 to rotate under the flushing of the heat exchange medium; and also includes a scraping member 33 that cooperates with the reciprocating screw 31, reciprocating in the heat exchange component 2, and cleaning the attachments in the heat exchange component 2;
[0028] The storage component 4 has an inlet connected to the outlet of the heat exchange component 2 and is used to store the steam after the heat exchange and the distillate generated after the heat exchange.
[0029] In a specific implementation, the conveying component 1 conveys the heat exchange medium to the heat exchange component 2, and the steam enters the heat exchange component 2 to exchange heat with the heat exchange medium. The heat of the steam is taken away by the heat exchange medium. At this time, the steam condenses into distillate and flows into the storage component 4 through the heat exchange component 2. As the heat exchange component 2 works for a long time, the impurities carried in the distillate will adhere to the heat exchange component 2. The conveying component 1 will flush the impeller 32 when conveying the heat exchange medium. The impeller 32 is driven by the reciprocating screw 31 to reciprocate along the setting direction of the reciprocating screw 31, thereby scraping off the impurities attached to the heat exchange component 2. The scraped impurities flow into the storage component 4 along the heat exchange component 2, thereby completing the cleaning of the heat exchange component 2.
[0030] In the utility model, during the process of conveying the heat exchange medium, the conveying component 1 causes the heat exchange medium to flush the impeller 32, thereby driving the scraping component 33 to clean the impurities on the heat exchange component 2, reducing the accumulation of impurities in the equipment and ensuring the heat exchange efficiency. The conveying component 1, the heat exchange component 2 and the cleaning component 3 cooperate with each other, which simplifies the cleaning work and reduces the work intensity of the staff while ensuring the sealing.
[0031] In one embodiment, the heat exchange component 2 includes an air pipe 21 arranged between the conveying component 1 and the storage component 4, and an air inlet pipe 22 is provided at one end of the air pipe 21 close to the conveying component 1, and steam enters the air pipe 21 through the air inlet pipe 22. A spiral heat exchange pipe 23 is provided in the air pipe 21, and the reciprocating screw 31 is rotatably arranged at the spiral center of the heat exchange pipe 23. The water inlet of the heat exchange pipe 23 is connected to the liquid delivery pipe 13, and the water outlet of the heat exchange pipe 23 extends from one end of the air pipe 21 close to the storage component 4, which is used to transport the heat exchange medium and exchange heat between the heat exchange medium and the steam, and transfer the heat exchange medium after absorbing heat to the next process.
[0032] With this design, steam enters the gas delivery pipe 21 through the air inlet pipe 22 and contacts the heat exchange pipe 23, and exchanges heat with the heat exchange medium in the heat exchange pipe 23. The spiral setting of the heat exchange pipe 23 allows the heat exchange medium to contact the steam for a longer time, thereby increasing the heat exchange time.
[0033] In one embodiment, the scraping member 33 includes a moving ring 331 that cooperates with the reciprocating screw 31. The reciprocating screw 31 rotates to drive the moving ring 331 to move back and forth on the reciprocating screw 31. An annular groove 3311 centered on the center of the moving ring 331 is provided on the outer wall of the moving ring 331, and a connecting plate 332 that rotates around the axis of the moving ring 331 is provided in the annular groove 3311. A cleaning ring 333 is provided at one end of the connecting plate 332 away from the moving ring 331, and the cleaning ring 333 is sleeved on the heat exchange tube 23. When the moving ring 331 moves, the moving ring 331 drives the cleaning ring 333 to move back and forth through the connecting plate 332.
[0034] With such a design, when the heat exchange medium flushes the impeller 32, the impeller 32 drives the reciprocating screw 31 to rotate, and the reciprocating screw 31 drives the moving ring 331 to move back and forth on the reciprocating screw 31. When the moving ring 331 moves, the moving ring 331 drives the cleaning ring 333 to move back and forth synchronously through the connecting plate 332, so that the cleaning ring 333 scrapes off impurities on the heat exchange tube 23.
[0035] It should be noted that the connecting plate 332 has a certain elasticity. When the moving ring 331 drives the cleaning ring 333 to move, the connecting plate 332 will be deformed according to the shape of the heat exchange tube 23 so that the cleaning ring 333 can fit the heat exchange tube 23 more closely.
[0036] In one embodiment, the storage component 4 includes a liquid storage tank 41 arranged at an end of the gas pipe 21 away from the air inlet pipe 22, which is used to store distillate formed by condensation of steam. A first partition plate 42 and a second partition plate 43 are spaced apart in the liquid storage tank 41 along the outlet direction of the heat exchange tube 23, and the height of the second partition plate 43 is lower than the first partition plate 42. The space between the first partition plate 42 and the inner wall of the end of the liquid storage tank 41 close to the gas pipe 21 is set as a first interval, the space between the first partition plate 42 and the second partition plate 43 is set as a second interval, and the space between the second partition plate 43 and the inner wall of the end of the liquid storage tank 41 away from the gas pipe 21 is set as a third interval, which is used to separate impurities in the distillate.
[0037] With this design, the distillate produced after heat exchange flows into the first section of the liquid storage tank 41 through the gas pipe 21. As the distillate stands still, the impurities in the distillate are stratified. As the distillate accumulates, the impurities with higher density in the distillate are precipitated in the first section, and the impurities with medium density in the distillate flow into the second section as the water level rises. As the distillate in the second section stands still, the distillate in the second section is also stratified. As the water level of the distillate in the second section rises, the impurities with lower density in the distillate flow into the third section, thereby completing the separation of the distillate.
[0038] In one embodiment, the conveying component 1 includes a water tank 11 arranged on one side of the air delivery pipe 21, which is used to store heat exchange medium. One end of the water tank 11 is connected to a water pump 12 for conveying heat exchange medium. The water outlet of the water pump 12 is provided with an infusion pipe 13, and the middle section of the infusion pipe 13 is vertically arranged. The water outlet of the infusion pipe 13 is connected to the water inlet of the heat exchange pipe 23, which is used to convey the heat exchange medium to the heat exchange pipe 23, and the above-mentioned impeller 32 is arranged in one end of the infusion pipe 13 close to the water outlet, so that when the heat exchange medium flows into the heat exchange pipe 23, the heat exchange medium drives the impeller 32 to rotate.
[0039] With this design, the heat exchange medium in the water tank 11 is transported to the water outlet of the infusion pipe 13 through the water pump 12. At this time, the water level of the heat exchange medium in the infusion pipe 13 rises, and the heat exchange medium flows into the heat exchange pipe 23 due to gravity. At this time, the heat exchange medium flushes the impeller 32 to drive the reciprocating screw 31 to rotate.
[0040] In one embodiment, the liquid storage tank 41 is provided with a condensation plate 44 near the gas outlet of the gas pipe 21 for condensing steam. With this design, after the steam undergoes heat exchange in the heat exchange component 2, there is still steam that has not been condensed by the heat exchange pipe 23. This steam flows into the liquid storage tank 41 through the gas pipe 21 and naturally rises to contact the condensation plate 44. The condensation plate 44 condenses the uncondensed steam into distillate and flows into the liquid storage tank 41.
[0041] In one embodiment, a demister 45 is provided on the liquid storage tank 41 for discharging steam in the liquid storage tank 41 to prevent the steam output from the gas transmission pipe 21 from accumulating in the liquid storage tank 41 .
[0042] With this design, since the efficiency of condensing steam by the condensing plate 44 is limited, as the gas pipe 21 transports steam and distillate into the liquid storage tank 41, the steam will accumulate in the inner cavity of the liquid storage tank 41, and the demister 45 removes the uncondensed steam in the liquid storage tank 41 to avoid steam accumulation.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "multiple", "multiple groups", and "several" refer to more than two.
