Through the physical properties of steam, steam is compressed into high-pressure and high-temperature gas during the compression process, so that it can be used in downstream systems. Steam compressors are widely used. For example, in the process of sewage treatment, the sewage can be heated, evaporated, condensed, and discharged to the outside with the help of steam compressors;

The present invention uses natural gas as fuel through a gas internal combustion engine, and the power output shaft of the gas internal combustion engine drives the steam compressor. The steam compression system uses a centrifugal compressor to reduce the pressure in the evaporator, thereby reducing the boiling point temperature of water and improving the evaporation efficiency.

The mounting rod 20 is fixedly connected to the left end of the movable frame 16, and the mounting rod 20 drives the mounting block 21 to form a sliding structure with the bent rod 22. The bent rod 22 is rotatably connected to the upper left end of the fixed cover 4 through a mechanical seal, and the bent rod 22 drives the cleaning brush 23 to clean the filter 24. The cleaning brush 23 is fitted at the left end of the filter 24. The upper and lower ends of the filter 24 are fixedly connected with positioning plates 25, and the middle part of the positioning plate 25 is engaged with a baffle 26. The baffle 26 is rotatably connected to the front end of the fixed cover 4, and the baffle 26 is fitted at the front end of the filter 24. The baffle 26 and the positioning plate 25 are limited by a fixing bolt 27. The fixing bolt 27 and the positioning plate 25 as well as the fixing bolt 27 and the baffle 26 are all threadedly connected;

[0049] like Figure 1 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13As shown, the sewage pipe is connected to the steam inlet pipe 5, and the sewage is passed into the treatment box 1 through the steam inlet pipe 5 and the fixed cover 4. When the sewage is passed, the solid impurities in the sewage can be filtered and treated by setting the filter screen 24. At the same time, the motor 14 is started, and the filter screen 24 drives the eccentric wheel 15 to rotate in the movable frame 16. At this time, the movable frame 16 drives the fixed bolt 27 and the limit block 18 to slide back and forth, thereby improving the stability of the movable frame 16 moving back and forth on the upper end of the fixed cover 4.

The baffle 26 rotates on the front side of the fixed cover 4. At this time, the baffle 26 is separated from the positioning plate 25 and the filter 24, thereby releasing the limit between the filter 24 and the fixed cover 4, and then the filter 24 is pulled out of the fixed cover 4, so that the filter 24 can be easily disassembled and cleaned, and the filter 24 can be prevented from being blocked during long-term use.

[0051] Embodiment 2: In an existing water vapor compressor with a condensed water recovery function, the condensed water generated after treatment is usually discharged directly to the outside, which is inconvenient to recover the condensed water generated during the treatment process. Therefore, by setting a water vapor compressor body 2, a heat pipe 3, a connecting pipe 28, a steam condensing device 29 and a valve 30, the water vapor compressor body 2 is installed at the upper end of the treatment box 1, the water vapor compressor body 2 is connected to the heat pipe 3, and the heat pipe 3 extends into the treatment box 1, and at the same time, the steam condensing device 29 is installed at the right end of the treatment box 1, and the lower end of the steam condensing device 29 is provided with a valve 30, and the steam condensing device 29 is connected to the treatment box 1 through the connecting pipe 28, as shown in FIG. Figure 1 , Figure 2 and Fig.14As shown, sewage enters the treatment box 1, and external steam is passed into the steam compressor body 2 through the steam interface set at the upper left end of the steam compressor body 2. The steam is further processed by the steam compressor body 2 and enters the hot pipe 3. The hot pipe 3 is immersed in the sewage inside the treatment box 1, so that it is convenient to heat the sewage. The heated sewage generates steam, and the steam enters the steam condensation equipment 29 through the connecting pipe 28 for condensation, and then is discharged to the outside by the valve 30, so as to facilitate the recovery of condensed water. At the same time, the steam heated in the hot pipe 3 returns to the steam compressor body 2 for reheating, and the cycle is repeated.

[0052] Embodiment 3: The existing water vapor compressor with condensate recovery function is not convenient for cleaning the impurities attached to the inside of the equipment, and it is not convenient to disassemble and clean the inside of the entire equipment. There is a lot of residue inside the equipment. Therefore, a connecting mechanism 8 is set. The upper and lower ends of the fixed cover 4 are provided with connecting mechanisms 8, and the connecting mechanism 8 drives the fixed cover 4 to form a disassembly structure at the left end of the processing box 1. The connecting mechanism 8 includes a connecting plate 9 fitted on the left side of the fixed block 6, an auxiliary plate 10 fixedly connected to the front and rear ends of the connecting plate 9, a fixing rod 11 fixedly connected to the left end of the processing box 1 and a fixing cap 12 for locking and limiting.

The middle part of the auxiliary plate 10 is penetrated by a fixing rod 11, and the outer surface of the fixing rod 11 is threadedly connected to a fixing cap 12. The fixing cap 12 is fitted on the left end of the auxiliary plate 10. Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, after use, the fixing cap 12 threadedly connected to the outer surface of the fixing rod 11 can be rotated, and the fixing cap 12 is disengaged from the fixing rod 11, thereby loosening the limit between the fixing rod 11 and the auxiliary plate 10, and then the connecting plate 9 is moved, and the connecting plate 9 drives the auxiliary plate 10 to disengage from the fixing rod 11, and at the same time, the connecting plate 9 is disengaged from the protrusion 7, thereby loosening the limit on the fixed cover 4, and then the fixed cover 4 is pulled to the left, so as to facilitate the cleaning of the interior of the processing box 1 and the fixed cover 4 and the filtered impurities to prevent residue.
