この発明は、液化ガスの通路を温めることにより、液化
ガスに気化熱を与えて気化させる液化ガスの気化器に関
す′る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquefied gas vaporizer that vaporizes the liquefied gas by applying heat of vaporization to the liquefied gas by heating the passageway of the liquefied gas.

た。In gas sterilizers and the like that use ethylene oxide gas to sterilize medical instruments, the gas used is stored in a cylinder in the form of liquefied gas, and when needed it is vaporized in a vaporizer and used. However, conventional vaporizers have a liquefied gas passage pipe wrapped around a heater or a sheathed heater with radiation fins installed in the liquefied gas passage, so it is difficult to heat the liquefied gas passage. The actual temperature was uneven. In other words, in the case of a vaporizer in which the pipe for the liquefied gas passage is wrapped around the heater, the side of the pipe for the liquefied gas passage that is in contact with the heater becomes high temperature, the opposite side becomes cold, and heat is dissipated into the liquefied gas passage. In the case of a vaporizer equipped with a sheathed heater with fins, the liquefied gas that comes into contact with the heater itself or the radiation fins receives extremely high heat, while the liquefied gas that does not come into contact with these passes through without receiving almost any heat. . For this reason, when a conventional vaporizer is used in a gas sterilizer that sterilizes medical instruments, for example, the liquefied gas that has not been sufficiently vaporized through the low-temperature part of the vaporizer is directly sent into the sterilization chamber and is used to sterilize medical instruments. adheres to,
There are drawbacks such as deterioration of plastic instruments and insufficient cleaning after sterilization.Additionally, when this conventional vaporizer is used to vaporize ethylene oxide gas, etc., the high temperature part of the vaporizer generates polymers. This has resulted in a drawback that the vaporizer adheres to the inside of the liquefied gas passage and deteriorates the performance of the vaporizer.
この発明は、上記の欠点を除去するためになされたもの
で、液化ガスの連路を温める際の温度むらをなくすこと
により、液化が完全に行われ、且つ、高温による重合物

目的とする。This invention was made in order to eliminate the above-mentioned drawbacks, and by eliminating temperature unevenness when heating the liquefied gas passage, liquefaction can be completed completely and polymers can be prevented from being produced due to high temperatures. The purpose is to provide a vaporizer for liquefied gas without any liquefied gas.

伝導のよいコンパウンド剤８で埋め込んだ構造である。As shown in FIG. 1, the gas sterilizer 1 stores objects to be sterilized, such as medical instruments, in a tank-shaped sterilization chamber 3 that can be sealed by closing a lid 2. The object to be sterilized is sterilized by filling it with a sterilizing gas such as ethylene oxide gas. The liquefied gas vaporizer 4 of the present invention is connected between a liquefied gas cylinder and the sterilization chamber 3 to vaporize the liquefied gas in the cylinder and send it to the sterilization chamber 3 as a gaseous sterilization gas. , in the example, the second
As shown in the figure and FIG. 3, it is provided in close contact with the outer wall of one end surface of the cylindrical sterilization chamber 3. This vaporizer 4 has a structure in which a heater 6 and a liquefied gas passage pipe 7 are embedded in a metal frame 5 with a compounding agent 8 having good thermal conductivity.

金属枠５の凹部９に充填される。The heater 6 is a ring-shaped sheathed heater, and is fitted into a groove 10 formed at the bottom of the recess 9 of the metal frame 5, with both ends protruding from the side surface of the metal frame 5 as terminals 11. The liquefied gas passage pipe 7 is a spirally wound steel pipe with good thermal conductivity, and is fitted into the recess 9 of the metal frame 5. In addition, the liquefied gas passage pipe 7 is connected at one end 12 to a liquefied gas cylinder (not shown), and at the other end 13 to a gas intake port 14 provided near the center of one end surface of the sterilization chamber 3. . The compounding agent 8 is a filler with good thermal conductivity made by mixing carbon, alumina powder, etc. and solidifying it with a binder, and is filled into the recess 9 of the metal frame 5 into which the heater 6 and the liquefied gas passage pipe 7 are fitted.

Then, the heat generated by the heater 6 spreads throughout the vaporizer 4 through the metal frame 5 and the compounding agent 8, which have good thermal conductivity, and flows through the liquefied gas passage pipe 7.
Warm the area evenly. When the vaporizer 4 is sufficiently warmed up, liquefied gas is fed from the cylinder and transferred through the spiral liquefied gas passage pipe 7. While the liquefied gas is transferred through the liquefied gas passage vibe 7, it absorbs vaporization heat from the evenly heated surrounding copper pipe wall and is sufficiently vaporized.
Gaseous sterilization gas passes through the gas inlet 14 into the sterilization chamber 3.

Furthermore, the liquefied gas passage pipe 7 is not limited to the steel pipe of the embodiment, but may be of any structure as long as it can be used as a liquefied gas passage. Further, the shape of the metal frame 5 is not limited to the ring shape as in the embodiment.

No polymers are produced.
