[0002] Medium-pressure flash evaporation utilizes the different evaporation effects of different pressures to achieve heat recovery. However, the high moisture content in the recovered gas during device operation affects the heat recovery effect. The "A Steam Condensate Flash Evaporation Recovery and Utilization Device" disclosed on the China Patent Network, with application number "202321858683.5", reduces the moisture content in the steam by setting a condensation cover plate and an absorber along the path of steam rising. The device reduces the moisture content in the steam by using steam to collide with the condensation cover plate and by the absorber to transfer the gas. However, because the cover plate and absorber have fixed structures and are located inside the device, the maintenance difficulty and cost of the device increase. Utility Model Content

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-5 This utility model provides a medium-pressure steam condensate flash evaporation recovery and utilization device, which includes: a mounting platform 1, a flash evaporation recovery device body 2 fixedly connected to the surface of the mounting platform 1, a material feeding port 11, a gas guiding port 10, and a water outlet port 9 fixedly connected to the side surface and lower end of the flash evaporation recovery device body 2, respectively, the gas guiding port 10 and the material feeding port 11 are distributed vertically opposite each other, the gas guiding port 10 is located at the upper end of the flash evaporation recovery device body 2, and a vacuum pump 19 is fixedly connected to the upper surface of the mounting platform 1, the vacuum pump 19 penetrating into the interior of the flash evaporation recovery device body 2, the vacuum pump 19 is used to increase the convenience of reducing the internal air pressure of the device.

[0023] Specifically, external substances enter the device through the material inlet 11, while condensed water is discharged through the water outlet 9, and steam is discharged through the gas inlet 10. The air pump 19 is turned on to quickly reduce the internal air pressure of the device by extracting gas.

[0024] An observation window 3 is fixedly connected to the surface of the flash evaporation recovery device body 2. The observation window 3 is used to observe the internal condition of the device. A positioning block 4 is provided at the front end of the observation window 3, and the front end of the positioning block 4 penetrates through the observation window 3. A sealing plate 8 is fixedly connected to the front surface of the positioning block 4, and the sealing plate 8 is engaged with the observation window 3. The sealing plate 8 is used to increase the sealing of the penetration point of the observation window 3. An elastic strip 16 is fixedly connected to the left surface of the positioning block 4, and the end of the elastic strip 16 away from the elastic strip 16 is engaged with the right surface of the positioning block 4. The flash evaporation recovery device body 2 is provided with an absorbent cotton pad 5 and a reinforcing frame 14 for absorbing water. The cotton pad 5 has a cavity 13 inside. When the device is in use, the elastic strip 16 is located inside the cavity 13. The absorbent cotton pad 5 is engaged with the positioning block 4. Both the elastic strip 16 and the absorbent cotton pad 5 are circular structures. The surface of the absorbent cotton pad 5 is provided with multiple through holes 18. The multiple through holes 18 are distributed in a circumferentially radiating structure. The cavity 13 is not connected to the outermost through hole 18. The left end of the elastic strip 16 is engaged with the right surface of the positioning block 4 in a socket-locking structure. The absorbent cotton pad 5 is used to absorb moisture in the floating steam. The elastic strip 16 serves as the skeleton of the absorbent cotton pad 5, which is used to expand and fold the absorbent cotton pad 5.

[0025] Specifically, when adding the absorbent pad 5, manually open the circular elastic strip 16 and pass it through the cavity 13 to integrate the absorbent pad 5 with the positioning block 4. Then, manually bend the absorbent pad 5 so that it passes through the observation window 3 and enters the interior of the device. Once the elastic strip 16 is free from external force, it automatically returns to its circular structure, thus unfolding the bent absorbent pad 5. The unfolded absorbent pad 5 then contacts the inner wall of the device, so the rising steam preferentially contacts the absorbent pad 5, and the moisture carried by the steam is directly absorbed by the absorbent pad 5, thereby separating the moisture carried by the steam.

[0026] The front end of the reinforcing frame 14 passes through the absorbent cotton pad 5 and is snapped onto the rear surface of the positioning block 4. Scrapers 15 are slidably connected to both the upper and lower surfaces of the reinforcing frame 14. The scrapers 15 are in contact with the surface of the absorbent cotton pad 5. A mounting frame 6 is slidably connected to the upper surface of the mounting platform 1. Two storage cavities 12 are provided at the upper end of the mounting frame 6. An automatic telescopic rod 7 is provided inside the storage cavity 12. The sliding part of the mounting frame 6 passes through the right surface of the mounting platform 1, and the width of the storage cavity 12 is greater than the width of the front end of the automatic telescopic rod 7. A connecting plate 17 is provided on the side of the scraper 15 away from the reinforcing frame 14. The connecting plate 17 is detachably threadedly connected to the scraper 15 by bolts. The output end of the automatic telescopic rod 7 passes through the observation window 3 and is snapped onto the connecting plate 17. The above components cooperate with each other to squeeze and separate the water absorbed by the absorbent cotton pad 5.

[0027] Specifically, the absorbent cotton pad 5 expands after absorbing water, and the distance between the scrapers 15 on the upper and lower sides of the absorbent cotton pad 5 is fixed. Therefore, the scrapers 15 directly squeeze the absorbent cotton pad 5 to remove the water absorbed by the absorbent cotton pad 5 during the back-and-forth sliding process. The automatic telescopic rod 7 extends and drives the scraper 15 to slide backward, and retracts and drives the scraper 15 to slide forward. During the back-and-forth sliding process of the scraper 15, the inner wall of the device restricts the range of motion of the scraper 15.

[0028] Working principle: During the process of steam rising, it comes into direct contact with the absorbent cotton pad 5. The presence of through holes 18 increases the contact area between the steam and the absorbent cotton pad 5. Then, the automatic telescopic rod 7 is activated to drive the scraper 15 to slide back and forth, thereby squeezing the absorbent cotton pad 5 which has expanded due to water absorption. After the absorbent cotton pad 5 is squeezed, the water it has absorbed is squeezed out, thus maintaining the water absorption efficiency of the absorbent cotton pad 5.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
