Problems solved by technology

In addition, when diluting formaldehyde with a large amount of water, the amount of water used increases and the running cost increases.
It should be noted that the environmental purification microreactor system disclosed in the following patent document 2 has also been proposed, but basically, it is suitable for a sterilization device using ethylene oxide gas (or a mixed gas with carbon dioxide gas), The use of water-sealed vacuum pumps is also denied (paragraphs 0003 and 0008 of Patent Document 2), and it is not a system that can be applied to low-temperature steam formaldehyde sterilizers

Embodiment Construction

[0071] Hereinafter, specific embodiments of the present invention will be described in detail based on the drawings.

[0072] figure 1 It is a schematic diagram showing a low-temperature steam formaldehyde sterilizing apparatus according to an embodiment of the present invention, and a part is shown in section.

[0073] The low-temperature steam formaldehyde sterilizing device 1 of the present embodiment has: a sterilizing tank 2, which accommodates sterilized objects; a water-sealed vacuum pump 3, which sucks and discharges the gas in the sterilizing tank 2 to the outside; water vapor and formaldehyde Gas introduction mechanism 4, which introduces water vapor and formaldehyde gas into the sterilization tank 2; external air introduction mechanism 5, which introduces external air into the sterilization tank 2; catalyst reactor 6, which decomposes and leads to the sterilization tank 2 Formaldehyde outside; and control mechanism (illustration omitted).

Abstract

The invention relates to a low temperature vapor formaldehyde sterilization device. In a low-temperature vapor formaldehyde sterilization apparatus using a water-sealed vacuum pump, formaldehyde is prevented from being dissolved into the sealing water, and a large amount of water for diluting formaldehyde is not required, thereby reducing running costs. The low-temperature vapor formaldehyde sterilization device includes a sterilization tank (2) for accommodating a sterilized product, and a water-sealed vacuum pump (3) for sucking and discharging the gas in the sterilization tank (2) to the outside; and a catalyst reaction The device (6) is disposed in an exhaust passage (9) leading from the sterilization tank (2) to the vacuum pump (3), and decomposes formaldehyde. It is preferable to switch the gas in the sterilization tank (2) through the catalyst reactor (6) or to discharge through the catalyst reactor (6) by changing the flow path of the exhaust passage (9).

Description

technical field [0001] The invention relates to a low temperature steam formaldehyde (LTSF) sterilizing device. Background technique [0002] Conventionally, as disclosed in Patent Document 1 below, a low-temperature steam formaldehyde sterilizer is known that sterilizes sterilized objects with water vapor containing formaldehyde in a sterilizer under vacuum. In this device, since water vapor is handled under vacuum, it is suitable to use a water-sealed type rather than a dry type vacuum pump. [0003] In the case of using a water-sealed vacuum pump, formaldehyde is dissolved in the sealing water, so even if it is diluted with a large amount of water, the formaldehyde will flow away, which is not preferable from the viewpoint of environmental protection. Moreover, when formaldehyde is diluted with a large amount of water, the usage-amount of water will increase and a running cost will increase. It should be noted that the environmental purification microreactor system disc...
