Description

Technical Field

[0001] This utility model relates to the field of steam sterilization technology, and in particular to a flash steaming device. Background Technology

[0002] Liquid hydrogen peroxide is highly corrosive and cannot be used for direct spraying for disinfection.

[0003] The flash evaporator works by instantly heating liquid hydrogen peroxide solution, causing it to vaporize and evaporate. The steam pressure, combined with the power of a fan, propels the hydrogen peroxide vapor rapidly into the disinfection space, achieving a disinfection effect. The heat storage tablets in the flash chamber are preheated to a high temperature. When liquid peroxide drips onto these tablets, it instantly vaporizes upon contact with the high-temperature surface, and the vapor is ejected from the disinfection port by the flowing air.

[0004] However, when the ambient temperature is low, the steam ejected from the disinfection port is prone to condensation, affecting disinfection efficiency and corroding items in the disinfection space. At the same time, when the ambient temperature is low, the temperature of the liquid medicine itself will also be low. When the liquid medicine drips onto the heat storage ingot, it will cause a sudden drop in the local temperature of the heat storage ingot. Continuous dripping will affect the vaporization effect and efficiency. Since the prerequisite for keeping the heat storage ingot at a high temperature is to continuously heat the heat storage ingot, once the liquid medicine dripping stops or the dripping rate slows down, the temperature of the heat storage ingot will become too high and difficult to cool down quickly, causing the droplets to bounce and splash, reducing the efficiency of continuous flash vaporization. Furthermore, excessively high temperatures also have a significant adverse effect on the lifespan of components. Utility Model Content

[0005] The purpose of this invention is to provide a flash vaporization device to solve the problems existing in the prior art and to help improve the efficiency of continuous flash vaporization.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] This utility model provides a flash vaporization device, including a flash vaporization group, a connecting hose, a heating group, and an injection pipe. A heat storage ingot is fixedly installed within the flash vaporization group. The space above the heat storage ingot within the flash vaporization group forms a flash vaporization chamber. A sterilization port is provided at the top of the flash vaporization group, allowing the flash vaporization chamber to communicate with the outside. The first end of the connecting hose is fixedly installed on the flash vaporization group and communicates with the flash vaporization chamber. The second end of the connecting hose is fixedly installed on the heating group and communicates with the interior of the heating group. An air inlet pipe is fixedly connected and communicates with the side wall of the heating group. The air inlet pipe is used to connect to an external fan, and the heating group can heat the air entering the heating group through the air inlet pipe. The first end of the injection pipe is fixedly installed on the side wall of the heating group and is used to connect to an external peristaltic pump. The injection pipe passes through the connecting hose from inside the heating group and enters the flash vaporization chamber. The second end of the injection pipe is placed in the flash vaporization chamber and can provide hydrogen peroxide droplets to the heat storage ingot.

[0008] Preferably, a heating rod is fixedly installed inside the heating assembly.

[0012] Preferably, the end face of each of the liquid distribution tubes that is away from the liquid distribution chamber can contact the top surface of the heat storage ingot.

[0013] Preferably, each of the liquid distribution tubes has a plurality of steam outlet grooves on the end face away from the liquid distribution chamber, and each steam outlet groove can connect the inside of the liquid distribution tube with the outside of the liquid distribution tube.

[0014] Preferably, a first temperature sensor is fixedly installed on the connecting hose, and the first temperature sensor is capable of detecting the temperature inside the connecting hose.

[0017] The present invention achieves the following technical advantages over the prior art:

[0018] The flash vaporization device provided by this utility model has an external fan connected to the air inlet pipe to provide flowing air to the flash vaporization group. Specifically, the fan blows air from the space to be disinfected into the heating group through the air inlet pipe, then into the flash chamber through the connecting hose, and finally out of the disinfection port to the space to be disinfected. The first end of the injection pipe is externally connected to a peristaltic pump to provide hydrogen peroxide droplets to the flash vaporization group. Specifically, the peristaltic pump injects the liquid into the flash chamber through the injection pipe. The hydrogen peroxide droplets vaporize upon contact with the heat storage tablets, and the resulting vapor is discharged into the space to be disinfected through the disinfection port with the flowing air. The heating group controls the air entering from the air inlet pipe. The air inside the heating unit is heated. On the one hand, the heated air flows and heats the injection pipe and the liquid medicine inside the injection pipe, increasing the temperature of the liquid medicine before it falls onto the heat storage tablet. This effectively avoids the problem of a sudden drop in the temperature of the flash chamber when the ambient temperature and the temperature of the injected liquid medicine are low. It is also easier to ensure the stability of the heating temperature in the flash chamber, prevent droplets from bouncing and splashing, and effectively prevent various problems caused by large local temperature changes in the heat storage tablet. It can also indirectly increase the temperature of the steam, effectively avoiding the problem of rapid condensation and condensation of steam when it encounters cold air, and further helps to improve the efficiency of continuous flash vaporization.
