Description

Technical Field

[0001] The utility model relates to the field of steam detection, in particular to a steam dryness detection device. Background Art

[0002] Steam is a commonly used heat source and power source in industry. The quality of steam has a very important impact on production efficiency and safety. The size of steam dryness directly reflects the quality of steam. If the steam dryness is small, the saturated steam contains more water, which not only reduces the production efficiency of steam equipment, but also affects the service life of equipment, aggravates corrosion, and causes energy waste, seriously affecting the economic benefits of enterprises.

[0003] A Chinese patent discloses a steam dryness detection device (authorization announcement number CN 211478129 U). This patented technology can solve the problems that the existing method for measuring steam dryness has high requirements for the sampling process, the sampling device is complex and the detection time period is long.

[0004] However, it takes a long process for the existing high-temperature steam to drop from high temperature to low temperature and then turn into water, and the detection time is relatively long. Condensed water is usually used to cool the steam. Long-term use of condensed water will easily increase the temperature, resulting in poor cooling effect. After the liquefied water of high-temperature steam is discharged, water marks are likely to remain at the outlet, resulting in inaccurate detection results for the next time.

The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0021] See also Figures 1 to 5 In this embodiment, a steam dryness detection device is provided, including a base 1 and a test bottle 2, an annular cavity 11 is installed on the upper end surface of the base 1, a connecting pipe 18 is installed on the upper end surface of the annular cavity 11 symmetrically installed front and back, a water tank 12 is installed on the upper end surface of the connecting pipe 18, the test bottle 2 is installed on the inner side wall of the water tank 12, a water outlet pipe is installed on the outer side wall of the annular cavity 11 symmetrically, a water pump 13 is installed on the other end of the water outlet pipe, a water inlet pipe is installed on the other end of the water pump 13, and the other end of the water inlet pipe is installed on the outer side wall of the water tank 12, an air inlet pipe is installed on the upper end surface of the test bottle 2, a circular tube 14 is installed at the bottom of the test bottle 2, a first valve is installed on the outer side wall of the circular tube 14, a device body is installed on the top of the test bottle 2, a pressure sensor 15 is installed at the bottom of the device body, a first temperature sensor 16 is arranged on the right side of the pressure sensor 15, and a pressure sensor 15 is installed on the bottom of the device body. A display panel 17 is installed on the front end face of the platform 1, and the display panel 17 is electrically connected to the device body. When working, a PLC program is written inside the device body to control the operation of each device. Steam enters the test bottle 2 through the air inlet pipe, and the first temperature sensor 16 detects the steam temperature. The pressure sensor 15 detects the internal air pressure of the test bottle 2. Then, cold water is added to the water tank 12 to physically cool the test bottle 2, which greatly increases the rate at which steam is liquefied into water. Then, the water temperature in the water tank 12 rises, resulting in poor cooling effect. At this time, the corresponding valve is opened, and water enters the annular cavity 11 through the connecting pipe 18 for static cooling treatment. When the cooling is completed, the water pump 13 is started to re-input the water in the annular cavity 11 into the water tank 12 to ensure the cooling effect on the test bottle 2.

[0022] The upper end surface of the test bottle 2 is installed with a cover plate 19 by threaded rotation, the bottom of the cover plate 19 is installed with a device body, and the outer side wall of the cover plate 19 is installed with a sealing gasket. When working, the sealing gasket structure is adopted to improve the sealing of the connection of the cover plate 19. The cover plate 19 is connected by threads, which is convenient for disassembly of the cover plate 19 and regular maintenance of the device body.

[0023] The upper end surface of the water tank 12 is symmetrically provided with a fixed cavity 21, a first slider is installed in the fixed cavity 21 by means of sliding fit, an L-shaped frame is installed at the inner end of the first slider, and the other end of the L-shaped frame is installed at the upper end surface of the test bottle 2. When working, the L-shaped frame is pulled upward to drive the test bottle 2 to move upward, and the test bottle 2 moves away from the water tank 12, so as to facilitate observation of the steam situation inside the test bottle 2 and the water content after liquefaction.

[0024] The bottom of the first sliding block and the bottom of the fixing cavity 21 are both provided with positioning grooves 22. When the test bottle 2 is moved to the fixed position, the fixing rod is placed in the positioning groove 22. The fixing rod plays a role of positioning and supporting the test bottle 2, so that the staff does not need to hold the test bottle 2 all the time to operate.

[0025] A fixed fan 23 is installed on the right end face of the base 1, and an elastic tube is installed on the right end face of the fixed fan 23. A connector 24 is installed on the other end of the elastic tube. The inner wall of the circular tube 14 is a threaded structure. When working, the first valve is opened, and water is discharged through the circular tube 14. Then the connector 24 is screwed to the inner wall of the circular tube 14, and the fixed fan 23 is started. Hot air enters the test bottle 2 through the elastic tube, thereby gasifying the water stains inside the circular tube 14 and the test bottle 2 to prevent the water stains from affecting the detection effect of the next experiment.

[0026] A second temperature sensor 25 is symmetrically installed at the bottom of the annular cavity 11. The second temperature sensor 25 is electrically connected to the display panel 17. When working, the second temperature sensor 25 detects the water temperature inside the annular cavity 11 and displays the specific value through the display panel 17 for easy observation and processing.

[0027] During specific operation, steam enters the test bottle 2 through the air inlet pipe, the first temperature sensor 16 detects the steam temperature, the pressure sensor 15 detects the internal air pressure of the test bottle 2, and then cold water is added to the water tank 12, thereby physically cooling the test bottle 2, which greatly increases the rate at which steam is liquefied into water. After that, the water temperature in the water tank 12 rises, resulting in poor cooling effect. At this time, the corresponding valve is opened, and water enters the annular cavity 11 through the connecting pipe 18 for static cooling treatment. When the cooling is completed, the water pump 13 is started to re-input the water in the annular cavity 11 into the water tank 12 to ensure the cooling effect on the test bottle 2.

[0028] Obviously, the invention described is only a part of the invention of the utility model, not the whole invention. Based on the invention in the utility model, all other inventions obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the utility model.
