[0018] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0019] A cyclone filter type steam-water separator test bench, such as Figure 1-13As shown, it includes an air supply pipe 4, which is fixedly connected to a water spray pipe 3. An adjusting mechanism for adjusting the air intake of the air supply pipe 4 and the water spray amount of the water spray pipe 3 is provided in the air supply pipe 4. The end of the air supply pipe 4 is fixedly connected to a filter bag cylinder 6. A first static pressure measuring point 5 is provided on the end of the air supply pipe 4 close to the filter bag cylinder 6. The first static pressure measuring point 5 is used to detect the moisture content of the gas intake. A drain port is provided at the bottom of the filter bag cylinder 6. The top of the filter bag cylinder 6 is fixedly connected to an exhaust pipe 7 by bolts. The bottom of the exhaust pipe 7 is detachably connected to a plurality of filter bags 19 located in the filter bag cylinder 6. The pore sizes and materials of 19 are different. These filter bags 19 with different pore sizes and materials can be used for different working conditions and different filtering precisions, which improves the applicability of the equipment and has a wider range of applications. The movable connection of the filter bag 19 makes it easy to remove the filter bag 19 for replacement. A switching mechanism for switching different filter bags 19 is provided in the filter bag cylinder 6. A second static pressure measuring point 9 is provided on the exhaust pipe 7. The second static pressure measuring point 9 is used to detect the outlet moisture content in the separated gas. The end of the exhaust pipe 7 is connected to the fan 12, and one end of the fan 12 is fixedly connected to the outlet Tube 18; the regulating mechanism includes a gas regulating unit, which is used to regulate the air intake of the gas pipe 4; the regulating mechanism includes a water spray regulating unit, which is used to regulate the water spray volume of the water spray pipe 3; when in use, the staff first connects the gas pipe 4 to the external gas source, and then connects the water spray pipe 3 to the external water source, and then controls the air intake of the gas pipe 4 and the water spray volume of the water spray pipe 3 through the regulating mechanism, so that the water content in the gas meets the requirements of the test. The regulating mechanism can synchronously regulate the air intake of the gas pipe 4 and the water spray volume of the water spray pipe 3, with high regulation accuracy, which solves the problem of inaccurate manual adjustment. High, which can easily cause a gap between the moisture content in the gas and the moisture content in the simulated test gas, resulting in inaccurate test results. Subsequently, the gas that meets the requirements enters the filter bag cylinder 6 for rotational separation, and the moisture in the gas will be thrown onto the inner wall of the filter bag cylinder 6, and flow downward under the action of gravity, and be discharged through the drain port of the filter bag cylinder 6. At the same time, the fan 12 is started, and the separated gas is sucked into the exhaust pipe 7 through the filter bag 19 under the suction action of the fan 12, and then discharged from the outlet pipe 18. The separation effect can be judged by comparing the detection data of the first static pressure measuring point 5 and the second static pressure measuring point 9.

[0020] The gas regulating unit includes blades 20. A plurality of circular array rotating shafts 201 are rotatably connected in the gas pipe 4 through a torsion spring. The blades 20 are fixedly connected to the rotating shaft 201. A fixed shaft 21 is fixedly connected in the gas pipe 4. One end of the plurality of rotating shafts 201 is rotatably connected to the fixed shaft 21.

A large bevel gear 23 is rotatably connected in the fixed shaft 21 through a rotating rod. The large bevel gear 23 is meshed with the small bevel gear 22. In order to ensure the synchronous movement of the blades 20, all the blades 20 can also be connected together through a connecting rod mechanism. When in use, the gas input from the external gas source into the gas pipe 4 will generate a certain wind force, which will push the blades 20 to rotate. The rotation of the blades 20 drives the small bevel gear 22 and the rotating shaft 201 to rotate. The small bevel gear 22 will drive the large bevel gear 23 to rotate. The rotation of the large bevel gear 23 will drive the other small bevel gears 22 to rotate synchronously, ensuring that all blades 20 are opened synchronously. When gas is no longer input into the gas pipe 4, the wind force generated by the gas on the blades 20 will disappear, and the rotating shaft 201 and the blades 20 will be reset under the elastic force of the torsion spring.

[0021] The water spray regulating unit includes a toothed disc 25, a movable groove 30 is provided in the water spray pipe 3, and the toothed disc 25 is sealed and slidably connected in the movable groove 30. The sealed toothed disc 25 can ensure that water does not flow out, and a plurality of rotating grooves 35 are provided on the toothed disc 25. A plurality of support rods located in the rotating grooves 35 are fixedly connected in the water spray pipe 3. The support rods are used to limit the rotation of the toothed disc 25. A plurality of pull rods 27 are rotatably connected to the top of the toothed disc 25. One end of the pull rod 27 is rotatably connected to a baffle 26. The baffles 26 are assembled into a circle. A baffle ring 28 located above the baffle 26 is fixedly connected in the water spray pipe 3. A connecting ring 36 is fixedly connected to the bottom of the baffle ring 28. The connecting ring 36 is rotatably connected to the side of the top of the baffle 26 away from the pull rod 27 through a plurality of connecting rods.

The rotating rod in the fixed shaft 21 is rotatably connected to the fixed shaft 21, and the end of the water spray pipe 3 located in the gas pipe 4 is provided with a nozzle 29, which is used to spray water evenly into the gas; when in use, the rotation of the blade 20 will drive the large bevel gear 23 to rotate, and the rotation of the large bevel gear 23 will drive the spur gear 24 to rotate, and the spur gear 24 will drive the toothed disk 25 to rotate, and the rotation of the toothed disk 25 will drive the pull rod 27 to move, and the pull rod 27 will drive the baffle 26 to open, thereby opening the channel in the water spray pipe 3, and the water in the water spray pipe 3 will be sprayed out from the nozzle 29. The water sprayed from the nozzle 29 can disperse the water flow, thereby increasing the water content in the gas.

[0022] The switching mechanism includes a support rod 31, a support rod 31 is fixedly connected to the exhaust pipe 7, a motor 32 is fixedly connected to the bottom of the support rod 31, and an output end of the motor 32 is fixedly connected to a rotating plate 33 that fits in with the top of the filter bag 19. The rotating plate 33 is rotatably connected to the exhaust pipe 7, and the through hole on the rotating plate 33 is located directly above the filter bag 19; when in use, when different filter bags 19 need to be switched for different working conditions, the staff starts the motor 32 to work, and the output shaft of the motor 32 rotates to drive the rotating plate 33 to rotate. When the through hole on the rotating plate 33 is above the required filter bag 19, the staff turns off the motor 32. At this time, the gas in the filter bag cylinder 6 will be filtered through the corresponding filter bag 19, which is convenient for using the corresponding filter bag 19 for different working conditions, which is more targeted and has a better filtering effect.

[0023] The outlet pipe 18 is provided with a plurality of swing plates 34 which are rotatably connected thereto. The swing plates 34 are connected to the outlet pipe 18 by a torsion spring. The end of the swing plates 34 which contacts the outlet pipe 18 is set to an arc shape. The arc shape can facilitate the swinging of the swing plates 34. The swinging direction of the swing plates 34 is toward the outlet. When in use, when the fan 12 discharges the separated gas outward through the outlet pipe 18, the separated gas will generate a certain wind force on the swing plates 34, which will push the swing plates 34 to swing under the action of the wind, and thus the separated gas can be discharged from the outlet pipe 18. When the gas-water separation is not performed, the fan 12 stops working, and the swing plates 34 are reset under the action of the torsion spring, and then the outlet pipe 18 can be closed to prevent impurities in the outside air from entering the outlet pipe 18 when not in use, thereby causing inconvenience to the staff in maintaining the equipment.

[0024] A valve is provided on the water spray pipe 3, and an air valve is provided on the air supply pipe 4. A water pump 2 is provided at the end of the water spray pipe 3 away from the air supply pipe 4. The bottom of the water pump 2 is fixedly connected to the water tank 1. A return pipe 17 is provided at the drain outlet at the bottom of the filter bag cylinder 6. One end of the return pipe 17 is connected to the water tank 1. During use, when gas-water separation is required, the staff opens the air valve on the air supply pipe 4, and the gas entering the air supply pipe 4 will be discharged after being regulated by the gas regulating unit; at the same time, the water pump 2 is started to work, and the water pump 2 pumps the water in the water tank 1 into the water spray pipe 3. The valve on the water spray pipe 3 is opened, and the water in the water spray pipe 3 will be discharged from the nozzle 29 after being regulated by the water spray regulating unit; after the moisture in the gas is separated, it will flow back to the water tank 1 from the return pipe 17, thereby recycling the water and saving water resources.

[0025] A blind flange 8 is provided on the exhaust pipe 7, a temperature and humidity sensor 10 is provided on the exhaust pipe 7, one end of the exhaust pipe 7 is movably connected to a silica gel dryer 11, one end of the silica gel dryer 11 is connected to the input end of the fan 12, a temperature and humidity sensor 13 and a flow meter 14 are provided on the outlet pipe 18, a plate 15 is provided at the bottom of the outlet pipe 18, and a bracket 16 is provided on the filter bag cylinder 6; when in use, when the separated gas passes through the temperature and humidity sensor 10, the temperature and humidity sensor 10 will detect the temperature and humidity of the gas, and then determine the temperature and humidity of the separated gas. The silica gel dryer 11 is used to dry and absorb the moisture in the passing gas, further reduce the moisture content in the gas, and improve the gas-water separation effect. The temperature and humidity sensor 2 13 detects the temperature and humidity of the gas after drying by the silica gel dryer 11, and then determines the temperature and humidity of the gas at this time. By comparing the detection data of the temperature and humidity sensor 10 and the temperature and humidity sensor 2 13, the moisture absorption of the silica gel dryer 11 can be judged. When the data of the two are similar, it indicates that the silica gel dryer 11 needs to be replaced, and then the staff can replace the silica gel dryer 11.

[0026] A method for testing the outlet moisture content of a cyclone filter type steam-water separator test bench, the specific steps of the method are as follows: 1) Preparation stage: Ensure the test bench is clean and all connections are correct without leakage; prepare a solution of potassium sulfate or other components with a certain mass concentration. 2) Gas introduction: Open the air valve on the gas pipe 4, start the water pump 2, open the valve on the water spray pipe 3, and introduce the gas containing a certain amount of water into the filter bag cylinder 6 through the regulating mechanism; 3) Operation of the equipment: Start the cyclone filter type steam-water separator to separate the gas containing a certain amount of water. The separated water will be discharged from the return pipe 17, and the separated gas will pass through the filter bag 19 and be discharged from the exhaust pipe 7; 4) Sampling: Sample the gas in the sampling hole covered by the blind flange 8 in accordance with GB / T16157-1996 and HJ836-2017; 5) Particle detection: After sampling, transport the sampling head back to the laboratory. Clean the outer surface of the sampling head with quartz wool dipped in acetone, place it in a 105-110°C oven for 1 hour, and after drying and cooling, place it in a constant temperature and humidity device for at least 24 hours. The balanced sampling head is weighed on a balance in the constant temperature and humidity device. The weighing steps and requirements are the same as before sampling. The difference in the sampling head weight before and after sampling is the mass of the particulate matter collected. 6) Data analysis: The liquid water content at the outlet is obtained by subtracting the mass concentration of the solution from the mass of the particulate matter and then subtracting the total gas flow rate of the sample.

[0027] Working principle: When in use, the staff first connects the gas pipe 4 to the external gas source, and then connects the water spray pipe 3 to the external water source, and then controls the air intake of the gas pipe 4 and the water spray volume of the water spray pipe 3 through the regulating mechanism, so that the water content in the gas meets the test requirements. The regulating mechanism can synchronously adjust the air intake of the gas pipe 4 and the water spray volume of the water spray pipe 3, with high adjustment accuracy, which solves the problem of low manual adjustment accuracy, which easily causes a gap between the moisture content in the gas and the moisture content in the simulated test gas, and inaccurate test results. Then the gas that meets the requirements enters the filter bag cylinder 6 is subjected to rotational separation, and the moisture in the gas will be thrown onto the inner wall of the filter bag cylinder 6, and will flow downward under the action of gravity and be discharged through the drain port of the filter bag cylinder 6. At the same time, the fan 12 is started, and the separated gas is sucked into the exhaust pipe 7 through the filter bag 19 under the suction action of the fan 12, and then discharged from the outlet pipe 18. The separation effect can be judged by comparing the detection data of the first static pressure measuring point 5 and the second static pressure measuring point 9; the gas input from the external air source entering the gas transmission pipe 4 will generate a certain wind force, which will drive the blades 20 to rotate, and the rotation of the blades 20 will bring The rotation of the small bevel gear 22 and the rotating shaft 201 drives the small bevel gear 22 to rotate, and the rotation of the large bevel gear 23 drives the other small bevel gears 22 to rotate synchronously, ensuring that all blades 20 are opened synchronously; when gas is no longer input into the gas pipe 4, the wind force generated by the gas on the blades 20 will disappear, and the rotating shaft 201 and the blades 20 will be reset under the elastic force of the torsion spring; the rotation of the blades 20 will drive the large bevel gear 23 to rotate, and the rotation of the large bevel gear 23 drives the spur gear 24 to rotate, and the spur gear 24 drives the toothed disc 25 to rotate, and the toothed disc 25 is rotated. The rotation of the toothed disc 25 drives the pull rod 27 to move, and the pull rod 27 drives the baffle 26 to open, thereby opening the channel in the water spray pipe 3, and the water in the water spray pipe 3 will be sprayed out from the nozzle 29. The water sprayed from the nozzle 29 can disperse the water flow, thereby increasing the water content in the gas; when different filter bags 19 need to be switched for different working conditions, the staff starts the motor 32, and the output shaft of the motor 32 rotates to drive the rotating plate 33 to rotate.
