The cleaning mode comprises various modes such as water cleaning, air blowing, spray cleaning and the like. Drying generally adopts modes such as air blow drying, heating drying and the like. The sterilization mode mainly comprises a dry heat sterilization mode and a wet heat sterilization mode, and the wet heat sterilization mode and the dry heat sterilization mode have the characteristics respectively, and the application ranges are crossed and different. The two sterilization mechanisms are different, and dry heat sterilization mainly causes the death of microorganisms through oxidation in a high-temperature environment. Moist heat sterilization is the death of microorganisms by irreversibly destroying enzyme proteins, structural proteins and nucleic acids in the microorganisms, causing coagulation denaturation of the proteins. Generally, the dry heat sterilization is carried out, and the temperature is kept at 160-180 ℃ for 2 hours, so that all microorganisms including spore bacteria can be killed. Is mainly used for sterilizing glassware, porcelain and the like. While the moist heat sterilization is generally performed at 60-134 ℃ for 4-60 minutes, and the sterilization effect with different requirements can be achieved. Moist heat sterilization and dry heat sterilization are difficult to completely replace each other.
In view of the above, it is often necessary to use multiple cleaning, drying and sterilizing devices simultaneously to meet different requirements for cleaning, sterilizing and drying multiple materials, instruments and apparatuses.

The scheme utilizes water and air as working media, utilizes the characteristic of low sonic speed of two-phase flow to design a shock wave generator, realizes two-phase supersonic flow and generates shock waves, and finishes the treatment of the surface of an object through the shock wave effect and the cavitation effect.
The above scheme considers the mode of guiding air by water, and the basic principle is 'water jet air extractor', namely, the air in the cavity is sucked by utilizing the energy of rapid jet of water flow, so that negative pressure is formed in the cavity again, and the external air is sucked.

If the conditions for generating shock waves need to be achieved, large-scale heating of water is also needed to be realized.
Based on this, above-mentioned scheme needs to set up the suction cavity in advance, carries out the process of mixing (convergent section) with higher speed earlier through Laval nozzle (convergent divergent nozzle) after the suction, again diffusion separation (divergent section). Therefore, the above solution requires the expansion of the remaining equipment such as the suction chamber and the like, and takes a lot of drainage (water) to be realized.

Further, the diffuser type air-water mixer 15 is composed of a convergent-divergent nozzle (laval nozzle) and a pipe assembly located therein. Wherein the convergent-divergent nozzle (laval nozzle) is composed of a large convergent tube 15a and an expanded tube 15b, and a piping assembly is inserted into a connection portion of the large convergent tube 15a and the expanded tube 15 b. The duct assembly comprises a small insertion caliber duct 15c, the duct outlet of the small insertion caliber duct 15c is directed towards the flared duct 15b side of the convergent-diffusive nozzle (laval nozzle).
Further, the small insertion caliber pipe 15c includes a vertical pipe and a bend at an end of the vertical pipe, the bend being directed toward the expanding pipe 15b side. Furthermore, the pipeline outlet of the elbow is welded with a small shrinkage pipe 15d.

The working principle and the working process of the invention are as follows:
when the cleaning and maintenance are to be carried out, for ordinary cleaning, the distilled water switching valve 3 is independently opened to carry out water cleaning, or the air compressor or the fan 1 is independently opened, the compressed air switching valve 2 carries out air blowing, the air compressor 1 is not provided with cooling equipment, and the temperature of a compressed air outlet can be fully utilized.
For instruments or containers with more dirt and impurities or high cleaning requirements, firstly, an air compressor 1 and a compressed air switching valve 2 are simultaneously started, then a distilled water switching valve 3 is started, distilled water and high-temperature compressed air can atomize and heat water through a diffusion type air-water mixer 15, and under the condition that the conditions are met, compressed air and water act through the diffusion type air-water mixer and can greatly reduce the local sound velocity by utilizing the occurrence of gas-liquid two-phase flow, so that a strong transonic shock wave effect can be generated at a low speed in an air-water mixture, the compressed air and the water are further fully mixed and atomized, and the temperature and the pressure of the air-water mixture are improved. Meanwhile, as the air compressor 1 is not provided with cooling equipment, the temperature of a compressed air outlet can be fully utilized, atomized water can be heated according to the Dalton partial pressure principle, and water vapor is formed at a lower temperature, so that a mixture of air, atomized water and water vapor is generated, and the air compressor has strong cleaning capability and can remove stubborn impurities.
When the sterilization state is realized, two different sterilization modes of dry heat and moist heat are selected according to requirements, if the dry heat sterilization mode is selected, an air compressor or a fan 1 is started, the compressed air switching valve 2 is closed, the distilled water switching valve 3 is closed, and the compressed air switching valve 2 adjusts the pressure of compressed air according to the feedback of a pressure measuring point 14 on the cleaning and sterilizing drying chamber 7. The compressed air enters the electric heater 4 for heating, and the power of the electric heater 4 is adjusted according to temperature and pressure temperature measuring points 13 on the cleaning, disinfecting and drying chamber 7. The flow regulating valve 5 regulates the opening according to a pressure and temperature measuring point 13 on the cleaning and disinfecting drying chamber 7, the steam exhaust valve 9 correspondingly switches to control the pressure of the cleaning and disinfecting drying chamber 7 not to exceed the standard according to the pressure and temperature feedback pressure of the pressure and temperature measuring point 13 on the cleaning and disinfecting drying chamber 7, and the temperature in the cleaning and disinfecting drying chamber 7 is maintained by means of dry air circulation to achieve the sterilizing effect. When the temperature and the pressure are insufficient, the cleaning, disinfecting and drying chamber 7 can be heated by the heating resistor 14 in an auxiliary manner until the temperature and the pressure are required.
If the moist heat sterilization mode is selected, the compressed air switching valve 2 is closed, the distilled water switching valve 3 is opened, and the distilled water switching valve 3 adjusts the pressure of the distilled water according to the feedback of the pressure measuring point 14 according to the pressure or the steam pressure of the hot water required by the cleaning, disinfecting and drying chamber 7. Distilled water enters the electric heater 4 to be heated, and the power of the heater is adjusted according to a pressure and temperature measuring point 13 on the cleaning, disinfecting and drying chamber 7. Hot water with different temperatures or saturated steam under corresponding water pressure can be generated according to the sterilization requirement. The flow regulating valve 5 adjusts the opening according to a pressure and temperature measuring point 13 on the cleaning and disinfecting drying chamber 7, the steam exhaust valve 9 feeds back a corresponding switch according to the pressure fed back by the pressure and temperature measuring point 13 on the cleaning and disinfecting drying chamber 7 so as to control the pressure of the cleaning and disinfecting drying chamber 7 not to exceed the standard, the drain valve 8 and the drain valve 11 are opened, and condensed water condensed by steam is discharged so as to ensure that the temperature and the pressure in the cleaning and disinfecting drying chamber 7 are maintained to achieve the sterilization effect. When the temperature and the pressure are insufficient, the cleaning, disinfecting and drying chamber 7 can be heated by the heating resistor 14 in an auxiliary way until the temperature and the pressure are required.
If a mixture wet-heat sterilization mode is selected, firstly, the air compressor 1 and the compressed air switching valve 2 are opened, then the distilled water switching valve 3 is opened, because the air compressor 1 is not provided with cooling equipment, the temperature of a compressed air outlet can be fully utilized, the distilled water and high-temperature compressed air can atomize and heat water through the diffusion type air-water mixer 15, and under the condition that the conditions are met, the compressed air and the water act through the diffusion type air-water mixer 15, and the local sonic velocity is greatly reduced due to the occurrence of gas-liquid two-phase flow, so that in the air-water mixture, a strong transonic shock wave effect can be generated at a lower speed, the compressed air and the water are fully mixed and atomized, and the temperature and the pressure of the air-water mixture are improved. Meanwhile, according to the Dalton partial pressure principle, the atomized water is heated to form water vapor at a lower temperature, so that a mixture of air, atomized water and water vapor is generated and enters the electric heater 4 to be heated, and the power of the heater is adjusted according to a pressure and temperature measuring point 13 on the cleaning, disinfecting and drying chamber 7. According to the Dalton partial pressure principle, air and water vapor mixture rather than single water vapor can be formed in the cleaning, disinfecting and drying chamber 7 under the condition of low heating temperature, and at the moment, superheated steam under the corresponding partial pressure water pressure can be generated according to the sterilization requirement without condensed water. The drain valve 8 and the drain valve 11 are closed to ensure that the temperature and the pressure in the cleaning, disinfecting and drying chamber 7 are maintained to achieve the sterilization effect. When the temperature and the pressure are insufficient, the cleaning, disinfecting and drying chamber 7 can be heated by the heating resistor 14 in an auxiliary way until the temperature and the pressure are required.
The contrast file in this patent application and the background art has the difference, and what the contrast file adopted is the drainage relation, the mode of water drainage air, and its rationale is "water jet air ejector", utilizes the energy that rivers jetted out fast promptly, sucks the air in the cavity to form the negative pressure in the cavity again, suction outside air. Based on its principle, if it is necessary to suck the same volume of air, it is necessary to use a drain (water) that greatly exceeds the object (air) to be sucked, i.e., it is necessary to suck several tens of cubes of air (several tens of kilograms in weight) with several tens of cubes (several tens of tons in weight) of water, which mainly cleans and utilizes water, and air bubbles mixed in the water. If the conditions for generating shock waves need to be achieved, large-scale heating of water is also needed to be possible.
The medium of the present patent application is a mixture of air, steam and water (referred to as gas-liquid two-phase flow or vapor-liquid two-phase flow for short), and in the medium, the sound velocity can be rapidly reduced to dozens of meters per second, so that the medium has the condition that supersonic speed generates shock waves under the condition of conventional speed, and simultaneously needs the coordination of a plurality of factors such as pressure, environment (gas-liquid two-phase flow), temperature and the like.
Therefore, the application of the patent has no drainage relation, the basic principle of the application is 'place condition required by generating shock wave', namely, the application creates objective condition capable of generating shock wave, and the water is fully atomized and mixed by utilizing shock wave phenomenon. Meanwhile, as the mixture mainly contains compressed air and a small part of atomized water, the water vapor partial pressure is lower according to the Dalton partial pressure principle, steam can be generated at a lower temperature (dozens of degrees), the temperature of a compressed air outlet can be fully utilized to heat the atomized water, and the water vapor is formed at the lower temperature, so that the mixture of air, atomized water and water vapor is generated.
Based on the principle, the device has no drainage relationship, mainly adopts high-temperature compressed air mixed with a small amount of atomized water and water vapor, mainly cleans the mixture of the utilized air, atomized water and water vapor, and takes the mixture as a main cleaning tool, thereby greatly saving water and energy.
Based on this, the laval nozzle (reducing and gradually expanding nozzle) is designed in the present application, the distilled water inlet pipeline is inserted into the connecting portion between the large contraction pipe 15a and the expansion pipe 15b, that is, the throat portion of the reducing and gradually expanding nozzle has the highest flow rate, the compressed air is accelerated to a temperature higher than the critical sound velocity of the mixture (several tens meters per second), and at the same time, the distilled water inlet pipeline inserted into the connecting portion is also necked down to accelerate to a temperature higher than the critical sound velocity of the mixture (several tens meters per second).
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be considered as the protection scope of the present invention.
