Description

Technical Field

[0001] This utility model relates to the technical field of low-temperature high-pressure sterilizers, and in particular to a low-concentration high-pressure mixed gas sterilizer of ethylene oxide. Background Technology

[0002] The ethylene oxide low-concentration high-pressure mixed gas sterilizer is a sterilization device specifically designed for heat-sensitive Chinese medicine finished products. It combines low-concentration ethylene oxide (EO), low-temperature environment and high-pressure conditions to balance sterilization effect and safety.

[0003] The sterilizers in the existing technology have the following disadvantages:

[0004] 1. The design pressure of ordinary ethylene oxide is 80 kPa. When a mixture of 10% EO and 90% CO2 is introduced, the pressure of the mixed gas is 1.5-2 kg. The original ethylene oxide body cannot withstand the pressure after mixing.

[0005] 2. The current sterilization medium (ethylene oxide) has a high concentration and requires a long desorption time;

[0006] 3. Some traditional Chinese medicines experienced severe caking and changes in powder content and morphology during high-temperature steam sterilization.

[0007] 4. Currently, the equipment occupies a large height and width, which limits the area where customers can place their equipment. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides a low-concentration high-pressure mixed gas sterilizer for ethylene oxide.

[0009] This utility model discloses a low-concentration, high-pressure mixed gas sterilizer for ethylene oxide, comprising a frame, a water jacket, an inner liner, and a sealing door. The water jacket is installed on the frame and wraps around the inner liner. A sealing door is provided at the opening of the inner liner. The device also includes a preheating and sterilization component, a humidification component, and a vacuum component. The preheating and sterilization component preheats the outer wall of the inner liner inside the water jacket and vaporizes the ethylene oxide gas into the inner liner. The humidification component humidifies the inner liner. In use, the container containing traditional Chinese medicine products is placed in the inner liner. The sealing door seals the inner liner wrapped in the water jacket. The vacuum component creates a vacuum inside the inner liner. The preheating and sterilization component is activated, preheating the inner liner and allowing the vaporized ethylene oxide gas to enter and sterilize the container. Simultaneously, the humidification component humidifies the inside of the inner liner, improving sterilization efficiency.

[0010] Preferably, the preheating and disinfection assembly includes a pipe heater, a circulating pump, and a vaporizer. All three are mounted on a frame and connected by pipes. The pipe heater heats the water, the circulating pump preheats the inner tank enclosed by the heated water, and the vaporizer contains a serpentine heat exchanger for vaporizing ethylene oxide gas. In use, the pipe heater heats the water to form hot water, the circulating pump delivers the hot water and preheats the outer wall of the inner tank, and then the hot water enters the vaporizer and vaporizes the ethylene oxide gas through the serpentine heat exchanger. The vaporized ethylene oxide gas then enters the inner tank to disinfect containers containing traditional Chinese medicine products.

[0011] Preferably, the humidification component includes a steam generator and a titanium rod filter. The steam generator and titanium rod filter are mounted on the frame. The output end of the steam generator is connected to the input end of the titanium rod filter through a pipe, and the output end of the titanium rod filter is connected to the input end of the inner tank. After the steam generator generates steam, it enters the titanium rod filter through the pipe for impurity filtration. The filtered steam enters the inner tank to increase the humidity of the internal air, thereby quickly bringing the humidity of the inner chamber to the set value.

[0012] Preferably, the vacuum assembly includes a liquid ring vacuum pump and a neutralization tank. The liquid ring vacuum pump is connected to the vacuum port of the inner tank via a check valve and a pneumatic ball valve. The output end of the liquid ring vacuum pump is connected to the input end of the neutralization tank. The inlet of the liquid ring vacuum pump is connected to the vacuum port of the inner tank via a check valve and a pneumatic ball valve. The desorbed gas enters the neutralization tank through the exhaust port of the liquid ring vacuum pump for waste gas treatment.

[0013] Preferably, it also includes an expansion tank, which is installed on the pipeline; the expansion tank can absorb the volume expansion of the closed water system due to the rise in water temperature, thereby stabilizing the system pressure. When the system pressure rises, the air bladder in the expansion tank will compress and absorb the excess medium to prevent the pipe from bursting due to excessive system pressure.

[0014] Preferably, it also includes a safety valve, a humidity probe, a pressure sensor, and a temperature sensor. The safety valve, humidity probe, pressure sensor, and temperature sensor are respectively installed on the inner liner wrapped by the water jacket. The safety valve, humidity probe, pressure sensor, and temperature sensor are all used to detect the internal environmental parameters of the inner liner. The humidity probe is used to detect the humidity inside the inner liner, the pressure sensor is used to detect the pressure inside the inner liner, the temperature sensor is used to detect the temperature inside the inner liner, and the safety valve is used to release pressure when the pressure inside the inner liner increases sharply.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the utensil containing the Chinese medicine product is placed in the inner liner, the sealing door panel seals the inner liner wrapped by the water jacket, the vacuum pumping component is operated to evacuate the inside of the inner liner, the preheating and disinfection component is started to preheat the inner liner and then allow ethylene oxide gas to vaporize and enter the inner liner to disinfect the utensil. At the same time, the humidification component humidifies the inside of the inner liner, thereby improving the disinfection efficiency. Attached Figure Description
