Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a steam sterilizer.

``Prior art'' The conventional steam sterilizer W1 uses piping to lead high-temperature steam from a heavy stationary boiler to the sterilization section, which requires a large amount of heat to evaporate pressure steam from the water surface contained in the boiler. Therefore, it was difficult to quickly and easily obtain high-temperature steam for sterilization and to simplify the equipment.0 ``Problems to be solved by the invention'' The present invention has simplified high-humidity steam for sterilization. ``Means for Solving the Problems'' The present invention aims to provide a steam sterilizer that can be quickly and easily obtained by using a device that can be quickly and easily obtained. By means of a steam sterilizer that forms a pressurized combustion chamber, a pressurized water nozzle is opened inside the sealed can, a steam transport passage is connected to the can, and a cooling water supply pipe is connected to the passage. configured.

``Operation'' Therefore, open the 8 idle valves of the steam transport passage, and in this state, pressurized air is injected into the sealed can from the pressurized air jet nozzle L1, and pressurized fuel is jetted from the same nozzle and ignited, inside the can. In the pressurized state, combustion occurs and the temperature and pressure inside the can rise. In this state, when pressurized water is jetted into the can from the pressurized water spouting water nozzle, the jetted water droplets are immediately heated and evaporated to become pressurized steam, which flows through the steam transport passage towards the target position. In the same passage, cooling water is supplied under pressure from the cooling water supply pipe, and the cooling water is evaporated by the transported high-temperature pressure steam, removes the heat of evaporation, cools the high-temperature steam to the required sterilization temperature, and sends it to the target location (sterilization). steam).

"Example" Mirror surface on one side of a sealed can 1 about the size of a drum can
A pressurized water nozzle 4 is inserted into the opening, and the other mirror surface 1 is opened.
A steam transport passage 5 is connected to the passage 5, and an on-off valve 7 is provided in the passage 5. The air jet nozzle 2 is connected to a two-piece air compressor, its receiver, etc., and the pressurized fuel jet nozzle 2 is connected to a white kerosene tank via a fuel horn through a tube. 4 is held at P//crll, and the inside of the open can 1 is made into a pressurized combustion chamber 3.The combustion chamber 3 is connected to a water tank through four jet water nozzles and a water pressure of 4 KP/cJ or more is applied. Spray water in the form of a spray 30
The pressure steam can be 0"C or more. This high temperature pressure steam enters the steam transport path 5 provided on the other mirror surface 1 and flows toward the pressure steam canister 8 provided at the target position while passing through the same transport path. Supply water pressurized from the cooling water supply pipe 6 connected to the transport passage 5 evaporates due to the steam in the transport passage 5 and removes the heat of evaporation, reducing the temperature of the high-temperature steam in the transport passage 5 to about 100"C. The end-pressure steam canister 8 is filled with the same high-temperature steam under pressure, and sterilizing steam of about 100"C is guided from the open canister 8 with a vibrator or hose 9 to sterilize tatami mats, straw grass, etc. The water particles ejected into the pressurized combustion chamber 3 not only evaporate but also decompose and combine with fuel and air to form water gases such as CO, H or H3. 10 is a safety valve, 11 is a pressure gauge, 12.13 is a drain discharge valve, 14 is an on-off valve for the water jet nozzle 4, and 15 is an on-off valve installed in the cooling water supply pipe 5. It is a valve.

"Effect" Since the present invention is configured as described above, unlike a boiler with a large evaporation area, the water droplets of the pressurized water jetted into the pressurized combustion chamber 3 are directly evaporated, and high-temperature pressure steam can be obtained efficiently, easily, and quickly. and by cooling it, it is possible to easily obtain sterilizing steam at the required temperature.
