Description

Technical Field

[0001] The present invention relates to the technical field of steam generators, and more specifically to a medical high-purity compressed steam generating device. Background Art

[0002] Steam generator (steam boiler) is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water and generate steam. The high-temperature or high-pressure steam generated can be widely used in medical disinfection, food processing, clothing and laundry, industrial production, central heating, and steam-driven fields of large vehicles, ships, power stations, etc., and has extremely high economic and social value. With the professionalization and intelligent development of steam generators, more and more manufacturers have launched small and intensive steam generators for different application fields. In particular, due to the widespread spread of viruses such as influenza in recent years, most manufacturers have launched small steam generators for sterilization and disinfection of medical devices, public places, and surfaces of objects. Such equipment uses the water vapor generated by the steam generator to kill harmful microorganisms such as bacteria and viruses, or uses the steam pressure of water vapor to clean, sweep, and disinfect public places and surfaces of objects.

[0003] At present, small steam generators all use a heating plate with a resistance wire as a heating source, heating the bottom of the vessel to turn water into steam. The low-purity, low-pressure steam generated by this equipment does not meet the hygienic requirements of medical-grade pure steam. The steam generated contains a large amount of inorganic or organic impurities, and the water and gas in the generated steam cannot be effectively separated. When used, the impurities in the water will be ejected along with the steam.

[0004] Since the steam ejected by such small steam generators has a high moisture content, low purity, and contains many impurities, if used in the medical and health field, such as in the ICU ward of a hospital, the water vapor containing metal ions will intrude and cause short circuit damage to various precision electronic instruments, which will not only cause property losses to the hospital, but also easily endanger the life and health of patients due to medical equipment failure. In addition, since the steam generated by such steam generators cannot meet the hygienic requirements of thoroughly cleaning the dirt on the surface of objects, the scope of use of such steam generators in the field of medical disinfection is also severely limited.

[0005] Therefore, it is necessary to improve the existing small steam generator to produce higher purity, lower energy consumption, and more convenient steam, expand the scope of use of the steam generator, and thus completely solve the problem that various medical precision electronic instruments are difficult to clean and disinfect. Summary of the invention

[0006] To sum up, the purpose of the present invention is to solve the technical deficiencies that the steam generated by the existing small steam generator has low purity and fails to meet the high-purity and high-quality standards of medical grade, thereby greatly limiting its application scope in the medical and health field, and to provide a medical high-purity compressed steam generating device that can produce higher purity, higher pressure, higher temperature and higher quality steam.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] A medical high-purity compressed steam generating device includes an industrial computer, a water tank, a water injection pump, a first one-way valve and a steam generator. The water tank is filled with pure water. The water outlet port of the water tank is connected to the water inlet port of the steam generator through a conduit via the water injection pump and the first one-way valve. The industrial computer controls the water injection pump to operate through a control circuit to pump the pure water in the water tank into the steam generator cavity through the first one-way valve. The steam generator cavity is provided with a first electric heating unit assembly located under the water surface. The industrial computer controls the operation of the first electric heating unit assembly through a control circuit to heat and vaporize the pure water in the steam generator cavity to generate steam. The top of the steam generator is provided with a first exhaust port for discharging the generated steam. The device also includes a steam booster pump, a second one-way valve and a compressed steam gas storage tank. The first exhaust port is connected to the air inlet port of the compressed steam gas storage tank through a conduit via the steam booster pump and the second one-way valve. The industrial computer controls the operation of the steam booster pump through a control circuit to pump the steam generated in the steam generator into the compressed steam gas storage tank through the second one-way valve. The compressed steam gas storage tank is provided with a pressure sensor for detecting the pressure in the tank and a second exhaust port for discharging the compressed steam in the tank. The pressure sensor is electrically connected to the data acquisition unit of the industrial computer to report the pressure sensing data in the tank to the microprocessor of the industrial computer. The microprocessor of the industrial computer is electrically connected to the steam booster pump through the control circuit, and controls the operation of the steam booster pump according to the received pressure sensing data to adjust or maintain the pressure in the compressed steam gas storage tank.

[0009] The compressed steam storage tank is provided with a temperature control device electrically connected to the industrial control machine for adjusting or maintaining the temperature inside the tank.

[0010] The temperature control device includes a second electric heating unit assembly, a heat-insulating layer and a temperature sensor. The second electric heating unit assembly is fixedly connected to the chamber or the tank wall of the compressed steam storage tank. The heat-insulating layer is coated on the outer wall of the compressed steam storage tank. The temperature sensor is electrically connected to the data acquisition unit of the industrial computer to report the temperature sensing data in the tank to the microprocessor of the industrial computer. The microprocessor of the industrial computer is electrically connected to the second electric heating unit assembly through a control circuit, and controls the operation of the second electric heating unit assembly according to the received temperature sensing data to adjust or maintain the temperature in the compressed steam storage tank.

[0011] The compressed steam storage tank is provided with a condensed water discharge device which is electrically connected to the industrial control machine and is used to discharge the condensed water in the tank.

[0012] The condensate discharge device includes a second drain port, a second electric control valve and a second liquid level sensor. The second drain port is provided at the bottom of the compressed steam storage tank, and its water outlet is connected to the second electric control valve through a conduit. The second liquid level sensor is electrically connected to the data acquisition unit of the industrial computer to report the liquid level sensing data of the condensate in the tank to the microprocessor of the industrial computer. The microprocessor of the industrial computer is electrically connected to the second electric control valve through a control circuit, and controls the switch of the second electric control valve according to the sensing data received from the second liquid level sensor to automatically discharge the condensate in the tank.

[0013] The steam generator is provided with a liquid level control device which is electrically connected to the industrial control machine and is used for automatically controlling the liquid level in the steam generator cavity.

[0014] The liquid level control device includes a return pipe, a first liquid level sensor, a first drain port and a first electric control valve. The first drain port is arranged at the bottom of the steam generator, and its water outlet is connected to the first electric control valve through a conduit. The water outlet port at the bottom of the return pipe is sealed and connected to the water inlet end of the first drain port, and the water inlet port at the top of the return pipe extends upward to the top of the first electric heating unit assembly. The first liquid level sensor is electrically connected to the data acquisition unit of the industrial computer to report the liquid level sensing data of the pure water in the steam generator to the microprocessor of the industrial computer. The microprocessor of the industrial computer is electrically connected to the first electric control valve and the water injection pump through the control circuit, and controls the switch of the first electric control valve and the operation of the water injection pump according to the sensing data received from the first liquid level sensor to automatically control or maintain the liquid level of the pure water in the steam generator chamber.

[0015] The industrial computer is provided with a display control panel.

[0016] The second exhaust port includes a dry steam exhaust port arranged at the top of the compressed steam storage tank and a wet steam exhaust port arranged at the bottom of the compressed steam storage tank. The dry steam exhaust port is connected to a dry steam switch through a conduit, and the wet steam exhaust port is connected to a wet steam switch through a conduit. A three-way joint is connected to the air outlet ports of the dry steam switch and the wet steam switch.

[0017] The steam generator and the compressed steam storage tank are respectively provided with a first safety valve and a second safety valve for pressure relief. The compressed steam storage tank is also provided with a negative pressure valve for preventing the negative pressure in the tank from causing damage to the equipment.

[0018] The beneficial effects of the present invention are as follows: the water tank is filled with purified water, impurities in the water are reduced at the water source end, the first electric heating unit assembly in the steam generator cavity is below the liquid level of the purified water, and is powered on under the control of the industrial computer to heat the purified water pumped in by the water injection pump, thereby generating low-purity and low-pressure steam with a temperature of about 100°C to 130°C and a pressure of about 0.1MPa to 0.8MPa in the steam generator, and the steam purity is not high. Then, under the control of the industrial computer, the low-purity and low-pressure steam generated in the steam generator is pumped into the compressed steam storage tank through the second one-way valve by the steam booster pump for compression and temporary storage.

[0019] Since the steam booster pump continuously pumps the low-purity, low-pressure steam generated in the steam generator into the compressed steam storage tank with limited volume, the low-purity, low-pressure steam is continuously compressed in the compressed steam storage tank, thereby increasing the pressure of the steam in the compressed steam storage tank. Moreover, during the boosting process, the low-purity, low-pressure steam will be liquefied in small amounts due to compression, and the trace impurities contained in the low-purity, low-pressure steam will be separated from the compressed steam along with the liquefied water droplets after the steam is liquefied, so that the steam in the compressed steam storage tank is further purified, and high-purity compressed steam is obtained.

[0020] Since the temperature of steam is positively correlated with the pressure of steam, after low-purity and low-pressure steam is compressed and pressurized in the compressed steam storage tank, the temperature of the high-purity compressed steam generated increases with the increase of pressure. Compared with the low-purity and low-pressure steam produced by the existing steam generator with a temperature of about 100°C to 130°C and a pressure of about 0.1MPa to 0.8Mpa, the high-purity compressed steam generated by the device of the present invention has higher purity, higher temperature and higher pressure, and fully meets the hygienic requirements of medical-grade pure steam. The increase in temperature is conducive to increasing the dry gas content in the high-purity compressed steam, reducing the steam with high humidity ejected outward by the device of the present invention during use, and the higher steam purity also greatly reduces the impurity content in the ejected steam. The steam generated by the device of the present invention can effectively avoid short-circuit damage caused by the injection of steam with high humidity and more impurities in precision medical equipment, reduce the risk of use, and enable the device of the present invention to be widely used in the field of medical and health care.

[0021] Moreover, the pressure range of the high-purity compressed steam generated by the device of the present invention is between 1.0 and 1.5 MPa. The higher steam pressure also makes the high-purity compressed steam generated by the device of the present invention have greater kinetic energy impact force. When used in actual disinfection, the strong steam pressure of the high-purity compressed steam can be used to impact and clean dirt and germs on the surface of objects, and the high temperature of the high-purity compressed steam brings better cleaning and disinfection effects, so that the device of the present invention can be widely used in environmental disinfection and property cleaning in hospitals and public places.

[0022] The high-purity compressed steam generated by the device of the present invention fully meets the medical-grade pure steam hygiene standards, is of high quality and good quality, and the higher steam temperature can release a large amount of heat during the liquefaction process when used for actual disinfection, thereby effectively killing viruses and microorganisms in the environment and on the surface of objects, so that the device of the present invention can be used in the field of medical steam disinfection with extremely high hygiene requirements or in the field of food processing, and has a wide range of applications.

[0023] In addition, the pressure sensor on the compressed steam storage tank of the present invention is connected to the data acquisition unit of the industrial computer to report the pressure data in the tank to the microprocessor of the industrial computer. The microprocessor of the industrial computer is connected to the steam booster pump through the control circuit, and according to the received pressure data in the tank, the operation of the steam booster pump is urgently adjusted to reduce, increase or maintain the amount of low-pressure pure steam pumped into the compressed steam storage tank, thereby automatically adjusting the pressure of the steam in the compressed steam storage tank. The system has a high degree of automation and good safety, reduces the workload of manual operation and safety monitoring, and has higher reliability.

[0024] Furthermore, the steam generator and the compressed steam gas storage tank of the present invention are also provided with a first safety valve and a second safety valve, respectively. In the actual use process, once the abnormal situation of steam pressure exceeding the standard occurs, the steam in the steam generator and the compressed steam gas storage tank will be automatically discharged from the first safety valve and the second safety valve to release the pressure, respectively, to prevent the steam generator or the compressed steam gas storage tank from exploding due to excessive pressure due to inability to operate when the electric control equipment fails, further improving the safety of the device of the present invention. Moreover, in order to avoid the problem that the pressure in the compressed steam gas storage tank is damaged due to the rapid liquefaction of the high-purity compressed steam in the tank due to abnormal situations such as rapid cooling inside the compressed steam gas storage tank, resulting in a sharp drop in the pressure inside the tank, which makes the pressure difference between the inside and outside of the tank too large, causing the negative pressure of the compressed steam gas storage tank to be damaged, the present invention also adds a negative pressure valve on the compressed steam gas storage tank to prevent negative pressure in the tank, further improving the safety of the device of the present invention.

[0025] Because the high-purity compressed steam in the compressed steam storage tank will liquefy and release heat during the continuous compression process, in order to adjust or maintain the temperature of the high-purity compressed steam in the tank, the present invention is provided with a temperature control device on the compressed steam storage tank. The high-purity compressed steam in the tank is heated by the second electric heating unit component provided in the compressed steam storage tank, thereby preventing the high-purity compressed steam in the tank from increasing the steam humidity or causing excessive condensation water in the tank due to the large amount of liquefaction caused by low temperature, thereby increasing the dry steam amount of the high-purity compressed steam in the tank. Moreover, the present invention is also coated with an insulation layer on the outer wall of the compressed steam storage tank, which can effectively prevent the heat of the steam in the tank from overflowing, which is not only beneficial to the heat preservation of the steam in the tank, but also can prevent the user from touching the compressed steam storage tank and causing burns, and is safer.

[0026] In addition, the compressed steam storage tank of the present invention is also provided with a temperature sensor electrically connected to the data acquisition unit of the industrial computer. The temperature sensor can detect the steam temperature in the tank in real time and report it to the microprocessor of the industrial computer. Then, the microprocessor of the industrial computer controls the operation of the second electric heating unit component according to the received temperature data in the tank, thereby achieving the purpose of automatically regulating or maintaining the temperature of the high-purity compressed steam in the compressed steam storage tank, so that the present invention can produce high-purity compressed steam with a higher temperature, and the temperature of the high-purity compressed steam generated by the device of the present invention can be adjusted and controlled at any time according to actual needs.

[0027] Furthermore, the compressed steam storage tank of the present invention is also provided with a condensed water discharge device, which detects the liquid level of the condensed water in the tank in real time through the second liquid level sensor. When the condensed water level reaches the preset maximum water level, the microprocessor of the industrial computer controls the second electric control valve to open through the control circuit, so that the condensed water in the tank is discharged outward through the second drain port under the impetus of the steam pressure in the tank, avoiding the accumulation of too much condensed water in the tank and affecting the dry steam volume and temperature of the high-purity compressed steam, thereby improving the quality of the high-purity compressed steam of the present invention. Moreover, the present invention automatically monitors and discharges the condensed water in the compressed steam storage tank through the industrial computer in conjunction with the second liquid level sensor and the second electric control valve, replacing the traditional manual observation and manual drainage operation mode, with a high degree of automation, reducing the amount of manual operation, and facilitating the continuous operation of the equipment.

[0028] Furthermore, the steam generator of the present invention is provided with a liquid level control device for automatically controlling the liquid level in the steam generator chamber. The pure water exceeding the standard liquid level is discharged to the outside of the steam generator through the first drain port and the first electric control valve through the reflux pipe. Because the water inlet port at the top of the reflux pipe is higher than the position of the first electric heating unit assembly, when the first electric control valve is opened for drainage under the control of the industrial computer, the liquid level in the steam generator will not drop below the first electric heating unit assembly, thereby preventing the first electric heating unit assembly from drying out and causing a malfunction of the present invention, and having high reliability.

[0029] The liquid level control device detects the pure water level in the steam generator cavity in real time through the first liquid level sensor. When the liquid level reaches the preset maximum liquid level value, the industrial computer controls the water injection pump to stop running to prevent the water in the water tank from continuing to be pumped into the steam generator, blocking the source of pure water. At the same time, the industrial computer controls the first electric control valve to open, discharge the excess pure water through the reflux pipe, and close the first electric control valve after the pure water in the reflux pipe is emptied, so that the liquid level in the steam generator cavity is flush with the water inlet port at the top of the reflux pipe, realizing the automatic control of the liquid level in the steam generator, reducing the workload of manual operation and monitoring, and having higher reliability.

[0030] Furthermore, because a small amount of water droplets will be generated due to liquefaction during the steam compression process, the high-purity compressed steam in the compressed steam storage tank is divided into a large amount of dry steam with extremely low water droplet content in the upper part and wet steam with relatively more water droplet content in the lower part. The present invention outputs the dry steam and wet steam in the tank through a three-way joint through a conduit via a dry steam switch and a wet steam switch, respectively, so that the outlet end of the three-way joint can spray pure dry steam, pure wet steam, or mixed steam mixed with dry steam and wet steam. In actual application, a steam spray gun can be connected to the outlet end of the three-way joint, which is more convenient to use. Therefore, the device of the present invention can spray different steams according to the requirements of steam humidity in different places, making the application range of the present invention wider.

[0031] In addition, the industrial computer of the present invention is also provided with a display control panel, through which the operator can understand the working status of the device of the present invention, and can control the operation of the water injection pump, the first electric heating unit assembly, the first electric control valve, the steam compression pump, the motor heat coil and the second electric control valve through the display control panel, thereby realizing manual operation control of the device of the present invention, further improving the controllability and safety of the present invention.

[0038] The structure of the present invention is further described below in conjunction with the accompanying drawings and preferred specific embodiments of the present invention. This embodiment is only a preferred implementation of the present invention and cannot be understood as limiting the present invention.

[0039] Reference Figures 1 to 5As shown, the present invention: a medical high-purity compressed steam generating device, including an industrial computer 1, a water tank 2, a water injection pump 3, a first non-return valve 4 and a steam generator 5. The industrial computer 1 is connected to the mains through a power switch 11 to provide power for the device of the present invention. The water inlet port of the water tank 2 is connected to a water treatment device 22 through a conduit via an inlet electric control valve 21. The water inlet port of the water treatment device 22 is connected to the water outlet of the tap water pipe to provide a continuous pure water source to the water treatment device 22. The tap water passing through the water treatment device 22 is purified into pure water and then flows into the water tank 2 through the inlet electric control valve 21. A water tank liquid level sensor 23 electrically connected to the data acquisition unit of the industrial computer 1 is also provided on the top of the water tank 2. The inlet electric control valve 21 is electrically connected to the microprocessor of the industrial computer 1 through a control circuit.

[0040] During actual use, if the water tank level sensor 23 detects that the liquid level in the water tank 2 drops, the microprocessor of the industrial computer 1 controls the water inlet electric control valve 21 to open through the control circuit, so that the pure water treated by the water treatment device 22 flows into the water tank 2 through the water inlet electric control valve 21. The water tank level sensor 23 detects the actual water level in the water tank 2 in real time. When the water level in the water tank 2 reaches the preset maximum water level, the microprocessor of the industrial computer 1 controls the water inlet electric control valve 21 to close through the control circuit to prevent the pure water treated by the water treatment device 22 from continuing to enter the water tank 2, thereby realizing automatic regulation of the liquid level in the water tank 2.

[0041] Specifically, refer to Figure 1 , Figure 2 and Figure 5 As shown, the water outlet port of the water tank 2 is connected to the water inlet port of the steam generator 5 through a conduit via the water injection pump 3 and the first one-way valve 4, and the water inlet port of the steam generator 5 is located at the bottom of the steam generator 5 so that pure water is gradually poured into the chamber of the steam generator 5 from bottom to top. The industrial computer 1 is electrically connected to the water injection pump 3 through a control circuit to control the operation of the water injection pump 3, so that the pure water in the water tank 2 is pumped into the chamber of the steam generator 5 through the first one-way valve 4 through the water injection pump 3. It should be noted that the first one-way valve 4 only allows pure water to flow from one end of the water tank 2 to one end of the steam generator 5, thereby preventing the pure water in the chamber of the steam generator 5 from being sucked back into the water tank 2.

[0042] Specifically, refer to Figure 1 , Figure 3 and Figure 5As shown, two first electric heating unit assemblies 51 located below the liquid surface of pure water and on the left and right sides of the steam generator 5 cavity are vertically provided in the steam generator 5 cavity. The industrial computer 1 is electrically connected to the two first electric heating unit assemblies 51 through a control circuit to control the operation of the first electric heating unit assemblies 51, so that the pure water in the steam generator 5 cavity is gasified through the two first electric heating unit assemblies 51 to generate low-purity and low-pressure steam with a temperature of about 100°C to 130°C and a pressure of about 1.3MPa to 2.0Mpa.

[0043] Specifically, a first exhaust port 52 for exhausting the generated low-purity and low-pressure steam is further provided on the top right side of the steam generator 5 .

[0044] It should be noted that a certain amount of space must be reserved in the upper part of the chamber of the steam generator 5 to accommodate the low-purity, low-pressure steam generated by the vaporization of pure water. Therefore, the water injection pump 3 cannot fill the chamber of the steam generator 5 when injecting water into it. At the same time, the water injection pump 3 cannot inject too little water into the chamber of the steam generator 5. It is necessary to ensure that the pure water pumped in can cover the first electric heating unit assembly 51 to prevent the first electric heating unit assembly 51 from drying out and causing damage to the equipment. Therefore, the steam generator 5 also needs to be provided with a liquid level control device for automatically controlling the liquid level in the chamber of the steam generator 5.

[0045] Preferably, the liquid level control device includes a return pipe 53 , a first liquid level sensor 54 , a first drain port 55 and a first electrically controlled valve 56 .

[0046] Specifically, the first drain port 55 is arranged at the middle position of the bottom of the steam generator 5, and its water outlet is connected to the first electric control valve 56 outside the bottom of the steam generator 5 through a conduit. The return pipe 53 is vertically arranged at the middle position of the two first electric heating unit assemblies 51 in the steam generator 5 cavity, and the water outlet port at the bottom of the return pipe 53 is sealed and connected to the water inlet end of the first drain port 55, and the water inlet port at the top of the return pipe 53 extends vertically upward and exceeds the top of the two first electric heating unit assemblies 51, so that the internal cavity of the steam generator 5 is connected to the external space through the return pipe 53, the first drain port 55 and the first electric control valve 56. The first liquid level sensor 54 is arranged at the top of the steam generator 5, and is electrically connected to the data acquisition unit of the industrial computer 1 to report the liquid level sensing data of the pure water in the steam generator 5 cavity to the microprocessor of the industrial computer 1.

[0047] In actual use, the first liquid level sensor 54 emits detection light to the pure water level in the steam generator 5 cavity, and obtains the pure water level sensing data according to the reflected light and the refracted light, and then reports the sensing data to the microprocessor of the industrial computer 1 through the I2C interface for processing.

[0048] During the process of water injection into the steam generator 5 cavity, the microprocessor of the industrial computer 1 controls the operation of the water injection pump 3 through the control circuit, so that the pure water in the water tank 2 is pumped into the steam generator 5 cavity through the first one-way valve 4 through the water injection pump 3. When the liquid level in the steam generator 5 cavity is above the two first electric heating unit assemblies 51 and rises to the water inlet port at the top of the return pipe 53, the pure water flows into the return pipe 53 through the water inlet port of the return pipe 53. During this process, the pure water level in the evaporator cavity will remain unchanged for a period of time and be level with the top of the return pipe 53. When the sensing data of the first liquid level sensor 54 received by the microprocessor of the industrial computer 1 remains unchanged, it can be proved that the first electric heating unit assembly 51 has been submerged by pure water. At this time, the microprocessor of the industrial computer 1 controls the first electric heating unit assembly 51 to be powered on through the control circuit, so that the pure water is heated and vaporized through the two first electric heating unit assemblies 51, so that low-purity and low-pressure steam is generated in the steam generator 5, and the generated low-purity and low-pressure steam is continuously discharged to the outside of the steam generator 5 cavity through the first exhaust port 52.

[0049] As the pure water is continuously pumped in, the inside of the return pipe 53 will eventually be filled with pure water, and then the liquid level in the steam generator 5 cavity will continue to rise. When the microprocessor of the industrial computer 1 receives the liquid level sensing data of the first liquid level sensor 54 and reaches the preset maximum liquid level, the microprocessor of the industrial computer 1 controls the water injection pump 3 to stop operating through the control circuit, preventing the pure water in the water tank 2 from continuing to be pumped into the steam generator 5 cavity, preventing the water level in the steam generator 5 cavity from being too high and affecting the generation of steam, and preventing the steam generator 5 cavity from being filled with pure water, causing the pure water to be discharged from the second exhaust port. Then, the microprocessor of the industrial computer 1 starts the first electric control valve 56 to open through the control circuit, so that the pure water in the steam generator 5 cavity flows out through the return pipe 53, the first drain port 55 and the first electric control valve 56, thereby reducing the pure water level in the steam generator 5 cavity.

[0050] Since the water inlet port at the top of the return pipe 53 of the present invention is higher than the top of the first electric heating unit assembly 51, when the pure water in the steam generator 5 cavity is discharged outward through the return pipe 53, the liquid level of the pure water will not be lower than the first electric heating unit assembly 51, ensuring that the first electric heating unit assembly 51 is always submerged in the pure water during the drainage process, avoiding the problem of exposing the first electric heating unit assembly 51 due to the low liquid level caused by excessive drainage, and improving the reliability and service life of the present invention. In addition, since the volume of the steam generator 5 cavity and the return pipe 53 is fixed, the time required to empty the pure water in the return pipe 53 is calculable, and the microprocessor of the industrial computer 1 controls the opening time of the first electric control valve 56 according to the calculated emptying time, so as to accurately control the discharge of excess pure water in the steam generator 5 cavity.

[0051] As the first electric heating unit assembly 51 is continuously powered on, the pure water level in the steam generator 5 cavity will gradually drop. When the liquid level drops to a preset minimum position, the microprocessor of the industrial computer 1 starts the water injection pump 3 through the control circuit to pump the pure water in the water tank 2 into the steam generator 5 cavity.

[0052] Through the above steps, the liquid level control function of the device of the present invention to automatically control or maintain the liquid level in the chamber of the steam generator 5 can be realized, with a high degree of automation, reducing the workload of manual operation and monitoring.

[0053] Specifically, the top of the steam generator 5 of the present invention is also provided with a first safety valve 57 for pressure relief. Since the pure water pumped into the steam generator 5 is continuously heated and vaporized, the steam pressure in the chamber of the steam generator 5 will continue to rise. If the industrial computer 1 fails due to some faults, the second electric heating unit assembly cannot be shut down in time or the steam booster pump cannot be turned on in time to discharge the generated steam, the steam pressure in the chamber of the steam generator 5 will continue to rise. Once the steam pressure in the chamber of the steam generator 5 exceeds the safety value, the generated steam will be automatically discharged from the first safety valve 57 to the outside of the steam generator 5, preventing the steam generator 5 from exploding due to the unlimited pressurization of the steam in the chamber of the steam generator 5, thereby improving the safety of the steam generator 5 of the present invention.

[0054] Specifically, refer to Figure 1 , Figure 4 and Figure 5 As shown, the device of the present invention also includes a steam booster pump 6, a second one-way valve 7 and a compressed steam gas storage tank 8 for compressing and pressurizing the low-purity and low-pressure steam generated in the steam generator 5. The first exhaust port 52 at the top of the steam generator 5 is connected to the air inlet port of the compressed steam gas storage tank 8 through a conduit via the steam booster pump 6 and the second one-way valve 7, and the air inlet port of the compressed steam gas storage tank 8 is at the bottom of the compressed steam gas storage tank 8. The microprocessor of the industrial computer 1 is electrically connected to the steam booster pump 6 through a control circuit to control the operation of the steam booster pump 6, so that the low-purity and low-pressure steam generated in the steam generator 5 is pumped into the compressed steam gas storage tank 8 through the first exhaust port 52 and the second one-way valve 7 through the steam booster pump 6. It should be noted that the second one-way valve 7 only allows the low-purity and low-pressure steam to flow from one end of the steam generator 5 to one end of the compressed steam gas storage tank 8, thereby preventing the high-purity compressed steam in the compressed steam gas storage tank 8 from flowing back into the steam generator 5.

[0055] As the low-purity, low-pressure steam generated in the steam generator 5 is pumped into the compressed steam storage tank 8 with limited volume, the low-purity, low-pressure steam pumped into the compressed steam storage tank 8 will be continuously compressed, so that the steam pressure in the compressed steam storage tank 8 rises accordingly. In order to monitor the pressure in the compressed steam storage tank 8 in real time and prevent the tank from exploding due to excessive pressure in the tank or insufficient pressure that cannot meet the use requirements, the present invention provides a pressure sensor 81 electrically connected to the data acquisition unit of the industrial computer 1 on the top of the compressed steam storage tank 8. In actual use, the pressure sensor 81 reports the pressure sensing data in the compressed steam storage tank 8 to the microprocessor of the industrial computer 1 in real time through the I2C interface. At the same time, the microprocessor of the industrial computer 1 is electrically connected to the steam booster pump 6 through the control circuit. The microprocessor of the industrial computer 1 automatically controls the operation of the steam booster pump 6 according to the received pressure sensing data to adjust or maintain the pressure in the compressed steam storage tank 8 to prevent the pressure in the tank from being too high or insufficient.

[0056] In actual use, the preset pressure value of the steam in the compressed steam storage tank 8 can be set according to the use requirements. When the steam pressure in the tank does not reach the preset value, the microprocessor of the industrial computer 1 controls the steam booster pump 6 to continue to operate through the control circuit, and continuously pumps the low-purity and low-pressure steam generated in the steam generator 5 into the compressed steam storage tank 8 for compressed storage. When the pressure sensor 81 detects that the steam pressure in the compressed steam storage tank 8 reaches the preset value, the microprocessor of the industrial computer 1 controls the steam booster pump 6 to stop operating through the control circuit, thereby preventing the pressure in the compressed steam storage tank 8 from continuing to increase, so that compressed steam with a set pressure value is generated in the compressed steam storage tank 8 of the present invention.

[0057] After the low-purity, low-pressure steam in the compressed steam storage tank 8 is compressed and pressurized, the compressed steam will be liquefied in small amounts due to the increased pressure. The water droplets generated by the liquefaction of the compressed steam cause the compressed steam to be divided into dry steam with less water droplet content, wet steam with more water droplet content, and condensed water formed by the aggregation of water droplets under the action of gravity. Since the dry steam has low humidity and low density, the dry steam of the compressed steam is mainly gathered in the upper part of the compressed steam storage tank 8; since the wet steam of the compressed steam has high humidity and high density, the wet steam of the compressed steam is mainly gathered in the lower part of the compressed steam storage tank 8; since the water droplets formed after the compressed steam is liquefied have the largest density, the water droplets in the compressed steam will gather downward along the inner wall of the compressed steam storage tank 8 at the bottom of the compressed steam storage tank 8 to form condensed water.

[0058] The water droplets generated by the liquefaction of compressed steam in the compressed steam storage tank 8 will carry away trace impurities doped in the low-purity and low-pressure steam, and the water droplets containing trace impurities will eventually gather at the bottom of the compressed steam storage tank 8 to form condensed water, so that the trace impurities in the original low-purity and low-pressure steam are completely separated from the compressed steam, thereby obtaining high-purity compressed steam with higher steam purity, ensuring that the high-purity compressed steam generated by the device of the present invention can meet the hygienic requirements of medical-grade pure steam, so that the device of the present invention can be applied to medical disinfection or food processing fields with high requirements on steam purity, thereby expanding the scope of use of the present invention.

[0059] Specifically, a second exhaust port is provided on the compressed steam storage tank 8, and a second drain port 82 is provided at the lowest point of the bottom of the compressed steam storage tank 8. During actual use, the high-purity compressed steam generated in the compressed steam storage tank 8 is discharged outward through the second exhaust port, and the condensed water generated in the compressed steam storage tank 8 is discharged outward through the second drain port 82.

[0060] Preferably, the second exhaust port includes a dry steam exhaust port 83 arranged at the top of the compressed steam storage tank 8 and a wet steam exhaust port 84 arranged at the bottom of the compressed steam storage tank 8, the dry steam exhaust port 83 is connected to a dry steam switch 85 outside the compressed steam storage tank 8 through a conduit, and the wet steam exhaust port 84 is connected to a wet steam switch 86 outside the compressed steam storage tank 8 through a conduit, and the outlet ports of the dry steam switch 85 and the wet steam switch 86 are connected to a steam spray gun 88 through a three-way joint 87.

[0061] It should be noted that in order to prevent the condensed water accumulated at the bottom of the tank from being discharged from the moisture exhaust port, the moisture exhaust port at the bottom of the compressed steam storage tank 8 of the present invention should be located above the highest liquid level of the condensed water.

[0062] The dry steam exhaust port 83 and the wet gas exhaust port provided on the compressed steam storage tank 8 of the present invention make full use of the high-purity compressed steam with different humidity in the compressed steam storage tank 8, so that the dry steam of the high-purity compressed steam with less or no water droplets in the upper part of the compressed steam storage tank 8 can be sprayed outwardly by the steam spray gun 88 through the dry steam switch 85 and the three-way joint 87; and the wet steam of the high-purity compressed steam with relatively more water droplets in the lower part of the compressed steam storage tank 8 can be sprayed outwardly by the steam spray gun 88 through the three-way joint 87 through the wet steam switch 86. In actual use, the humidity of the high-purity compressed steam sprayed outwardly by the steam spray gun 88 can be controlled by switching the dry steam switch 85 and the wet gas switch, thereby expanding the application range of the high-purity compressed steam generated by the device of the present invention. For example, when dry steam is needed, it is only necessary to open the dry steam switch 85 and close the wet steam switch 86, so that dry steam of high-purity compressed steam can be sprayed outward through the steam spray gun 88; when dry-wet mixed steam is needed, the dry steam switch 85 and the wet steam switch 86 can be opened at the same time, so that dry-wet mixed steam of high-purity compressed steam can be sprayed outward through the steam spray gun 88; when wet steam is needed, it is only necessary to open the wet steam switch 86 and close the dry steam switch 85, so that wet steam of high-purity compressed steam can be sprayed outward through the steam spray gun 88.

[0063] Since the temperature of steam is positively correlated with the pressure, the low-purity, low-pressure steam in the compressed steam storage tank 8 will release a certain amount of heat to the outside due to liquefaction during the compression and pressurization process, thereby causing the temperature in the compressed steam storage tank 8 to rise. If the insulation effect of the compressed steam storage tank 8 is poor, the speed at which the high-purity compressed steam in the tank releases heat to the outside will be accelerated, thereby promoting the liquefaction of the high-purity compressed steam in the tank, thereby causing the dry steam content of the high-purity compressed steam in the tank to decrease and the moisture content to increase, and condensed water is easily accumulated in the tank, which seriously affects the quality of the high-purity compressed steam in the tank. In order to regulate and maintain the temperature in the compressed steam storage tank 8 of the present invention, prevent the excessive liquefaction of the high-purity compressed steam in the tank from causing excessive moisture content in the tank, and avoid the condensed water in the tank from accumulating too quickly and too much, and also in order to regulate the temperature of the high-purity compressed steam in the tank, the compressed steam storage tank 8 of the present invention is also provided with a temperature control device electrically connected to the industrial computer 1.

[0064] Preferably, the temperature control device includes a second electric heating unit assembly 89, an insulation layer 90 and a temperature sensor 91, the second electric heating unit assembly 89 is coiled on the inner wall of the compressed steam storage tank 8, the insulation layer 90 is covered on the outer wall of the compressed steam storage tank 8, and the temperature sensor 91 is arranged on the tank wall of the compressed steam storage tank 8 and is electrically connected to the data acquisition unit of the industrial computer 1 through the I2C interface. When in use, the temperature sensing data in the compressed steam storage tank 8 is reported to the microprocessor of the industrial computer 1 through the temperature sensor 91.

[0065] Specifically, the microprocessor of the industrial computer 1 is electrically connected to the second electric heating unit assembly 89 through a control circuit. During actual use, the microprocessor of the industrial computer 1 controls the operation of the second electric heating unit assembly 89 according to the received temperature sensing data to adjust or maintain the temperature inside the compressed steam storage tank 8.

[0066] In actual use, the preset maximum temperature of the high-purity compressed steam in the compressed steam storage tank 8 can be set according to the use requirements. When the temperature in the compressed steam storage tank 8 is lower than the set value, the microprocessor of the industrial computer 1 controls the second electric heating unit assembly 89 to be powered on through the control circuit, so as to further heat the high-purity compressed steam in the compressed steam storage tank 8 through the second electric heating unit assembly 89, thereby increasing the temperature of the high-purity compressed steam in the tank, and at the same time, it is also beneficial to increase the dry steam amount of the high-purity compressed steam in the tank and reduce the generation of condensed water. When the temperature of the high-purity compressed steam in the tank reaches the preset temperature value, the microprocessor of the industrial computer 1 controls the heating coil to cut off the power or reduce the temperature through the control circuit to prevent the temperature of the high-purity compressed steam in the tank from further increasing, and to prevent the high-purity compressed steam from affecting the pressure of the steam in the tank due to the increase in temperature.

[0067] The present invention heats the high-purity compressed steam in the compressed steam storage tank 8 through the second electric heating unit assembly 89 of the temperature control device, effectively solving the problem of the high-purity compressed steam in the tank causing the dry steam content to decrease, the wet steam content to increase, and the excessive condensed water due to the fast liquefaction speed of the high-purity compressed steam in the tank, thereby improving the quality of the high-purity compressed steam in the compressed steam storage tank 8 of the present invention. At the same time, the temperature control device provided in the present invention can set the temperature of the high-purity compressed steam in the compressed steam storage tank 8 according to actual needs, so that the temperature of the high-purity compressed steam generated by the device of the present invention is higher than the temperature of the low-purity and low-pressure steam generated by the existing steam generator 5, so that the device of the present invention can be used in places with higher requirements for steam temperature, further expanding the application range of the device of the present invention.

[0068] In addition, the thermal insulation layer 90 coated on the outer wall of the compressed steam storage tank 8 of the present invention can not only effectively prevent the heat of the steam in the tank from overflowing, which is beneficial to the thermal insulation of the steam in the tank, but also prevent the user from touching the tank wall of the compressed steam storage tank 8 and causing burns, which is safer.

[0069] Specifically, since condensed water is constantly accumulating in the compressed steam storage tank 8, in order to prevent excessive condensed water from accumulating in the tank and affecting the temperature and humidity of the steam in the tank, the present invention also provides a condensed water discharge device on the compressed steam storage tank 8, which is electrically connected to the industrial computer 1 and is used to discharge the condensed water in the tank.

[0070] Preferably, the condensate discharge device includes a second drain port 82, a second electric control valve 92 and a second liquid level sensor 93. The second drain port 82 is arranged at the lowest position of the bottom of the compressed steam storage tank 8, and the water outlet port of the second drain port 82 is connected to the second electric control valve 92 located outside the bottom of the compressed steam storage tank 8 through a conduit, so as to ensure that the condensate gathered in the tank can be discharged from the water outlet port of the second drain port 82 through the second electric control valve 92 to the outside of the tank. The second liquid level sensor 93 is arranged on the tank wall of the compressed steam storage tank 8, and is electrically connected to the data acquisition unit of the industrial computer 1 through the I2C interface to report the liquid level sensing data of the condensate in the tank to the microprocessor of the industrial computer 1. The microprocessor of the industrial computer 1 is electrically connected to the second electric control valve 92 through the control circuit, and controls the switch of the second electric control valve 92 according to the sensing data received from the second liquid level sensor 93 to automatically discharge the condensate in the tank.

[0071] In actual use, the second liquid level sensor 93 emits detection light to the condensed water level in the compressed steam storage tank 8, and obtains the liquid level sensing data of the condensed water in the tank according to the reflected light and the refracted light, and then reports the sensing data to the microprocessor of the industrial computer 1 for processing through the I2C interface. When the condensed water level sensing data received by the microprocessor of the industrial computer 1 reaches the preset maximum liquid level, the microprocessor of the industrial computer 1 controls the second electric control valve 92 to open through the control circuit, so that the condensed water gathered at the bottom of the tank is driven by the high-purity compressed steam in the tank and discharged from the second drain port 82 at the bottom of the tank through the second electric control valve 92, until the second liquid level sensor 93 senses that the condensed water at the bottom of the tank is drained, and the microprocessor of the industrial computer 1 controls the second electric control valve 92 to close through the control circuit.

[0072] The condensate discharge device provided by the present invention is realized by the cooperation of the industrial computer 1, the second liquid level sensor 93 and the second electric control valve 92 to realize the function of automatically detecting and discharging the condensate in the compressed steam storage tank 8. Compared with the manual observation method, the glass liquid level observation device is omitted, the tank structure design is simplified, and it is beneficial to improve the overall structural strength of the tank body, so that it has a better pressure-bearing effect. Moreover, the automatic detection and discharge of condensate by the industrial computer 1 also saves the workload of manual operation, has a high degree of automation, accurate detection, and timely discharge, which is beneficial to controlling the humidity of the high-purity compressed steam in the tank and improving the quality of the high-purity compressed steam in the tank.

[0073] Specifically, the top of the compressed steam storage tank 8 of the present invention is also provided with a second safety valve 94 for pressure relief. Since the low-purity and low-pressure steam pumped into the compressed steam storage tank 8 is continuously compressed, the steam pressure in the tank will continue to rise. If the industrial computer 1 fails due to some faults, the steam booster pump 6 cannot be shut down in time or the high-purity compressed steam in the tank cannot be discharged in time, the steam pressure inside the compressed steam storage tank 8 will continue to rise. Once the pressure in the tank exceeds the safety value, the high-purity compressed steam will automatically be discharged from the second safety valve 94 to the outside of the tank body, preventing the tank body from exploding due to the unlimited pressurization of the high-purity compressed steam in the tank, thereby improving the safety of the compressed steam storage tank 8 of the present invention.

[0074] Furthermore, the top of the compressed steam storage tank 8 of the present invention is also provided with a negative pressure valve 95 for preventing damage to the equipment caused by negative pressure in the tank. Since the compressed steam storage tank 8 stores high-purity compressed steam, once the temperature of the high-purity compressed steam inside the tank body drops sharply, causing the steam to liquefy quickly and the steam volume to decrease rapidly, it will cause a sharp drop in the pressure inside the tank. Once the pressure inside the tank is less than the pressure outside the tank, it will cause negative pressure inside the compressed steam storage tank, thereby causing damage to the tank body under the action of an air hammer. The negative pressure valve 95 provided on the compressed steam storage tank 8 of the present invention can automatically connect the inside and outside of the tank when negative pressure occurs in the tank, so that the air outside the tank is automatically replenished into the tank, preventing atmospheric pressure from squeezing the compressed steam storage tank 8 and causing damage to it, further improving the safety of the compressed steam storage tank 8 of the present invention.

[0075] Preferably, since the present invention adopts the industrial computer 1 to automatically control the overall operation of the device, in order to avoid the problem that the industrial computer 1 cannot automatically control the operation of various electronic control devices due to equipment failure, the present invention adds a display control panel 10 on the industrial computer 1, which is electrically connected to the microprocessor of the industrial computer 1 and is used for manual intervention or taking over the device and performing manual operation control.

[0076] Specifically, the display control panel 10 is provided with a display screen 101 and a control button 102. The display screen 101 of the display control panel 10 receives the display signal sent by the microprocessor through the display circuit to display the sensing data of the water tank liquid level sensor 23, the first liquid level sensor 54, the second liquid level sensor 93, the temperature sensor 91 and the pressure sensor 81, so that the operator can conveniently obtain the liquid level in the water tank 2, the liquid level in the steam generator 5, and the condensed water level, steam temperature and pressure in the compressed steam storage tank 8 through the display. The control button 102 of the display control panel 10 sends a manual control signal to the industrial computer 1 through the control circuit to manually control the operation of the water inlet electric control valve 21, the water injection pump 3, the first electric heating unit assembly 51, the first electric control valve 56, the steam booster pump 6, the second electric heating unit assembly 89 and the second electric control valve 92, so that the operator can control the operation of each electrical device according to the information displayed on the display screen 101 to realize the manual operation control of the device of the present invention, making the control mode of the device of the present invention more flexible.

[0077] The above embodiment is only for the purpose of clearly describing a specific implementation of the present invention, and is not intended to limit the implementation of the present invention. For those skilled in the art, other adjustments or changes to the industrial computer 1, the water tank 2, the steam generator 5, the steam booster pump 6, the compressed steam storage tank 8, etc. can be deduced and summarized based on the principles of the present invention, which will not be listed one by one here. Any modification, replacement or improvement made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
