Abstract

PURPOSE:To prevent transfer of unpurified water from an evaporating vessel to a condensing vessel in the case of occurrence of vibration or turning sideways and to eliminate requirement for an entrainment collector and bumping inhibitor by providing a diaphragm having both waterproofing effect and permeability for water vapor and separating the evaporating vessel from the condensing vessel. CONSTITUTION:A porous polytetrafluoroethylene sheet 3 is provided between an evaporating vessel 1 and a condensing vessel 2. Unpurified water fed from a water feeding port 5 is converted to steam by heating with a heater 4. The steam passes through the sheet 3 and is transferred to the condensing vessel 2, liquefied by being cooled by a metallic net 9 cooled by a fan 10, and is discharged from an outlet port 7 of purified water.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application Refined carbon is one of the substances used in the largest quantities in all industries. In recent years, compact, lightweight and highly portable hydrogen generators using water electrolysis for gas chromatographs and boron-oxygen mixture generators using water electrolysis for torches have been put into practical use. Highly purified water with a resistivity of 1 μs or less must be supplied to all of these.

Prior Art Conventionally, these devices require that purified water be prepared in a make-up tank before use. In particular, if you use the product outdoors for a long time in any location where it is not possible to easily supply water, it is necessary to install a larger water tank.

Not only does it not take full advantage of the device's original characteristics of being small, lightweight, and highly portable, but it also has the essential problem of having to periodically replenish water.

In order to solve this problem, a purification device that produces highly purified water from water that is relatively easy to obtain, such as river water, tap water, and rainwater, can be installed instead of a water replenishment tank. The ion exchange method and the distillation method have traditionally been commonly used in the Water Essence W method, but the former requires periodic replacement or regeneration of the ion exchange resin, making maintenance extremely troublesome. be. On the other hand, the latter requires only a heat source such as electricity, and has the advantage of requiring less maintenance than the former.

Problems to be Solved by the Invention However, conventional distillation apparatuses have either a hollow tube between the water evaporation container and the condensation container, or a single packing to prevent droplets from scattering from the evaporation container during bumping. They are simply connected by tubes filled with First, when transporting, the T-roller vibrates violently, stiffens, rolls over, and when it rolls over, unpurified water moves from the evaporation container to the condensation container, causing problems in portability. In order to prevent impurities from scattering into the condensation vessel, additional measures must be taken to prevent stiffness and bumping by packing an optical filler.
However, the structure of the distillation equipment is complicated, making it difficult to downsize.
One.

Conventionally, there was only one technique to solve these problems.

The present invention takes advantage of the advantages of the distillation apparatus, while using the conventional apparatus N.
We aim to completely solve the problem of impurity migration or scattering from the boiling vessel to the condensing vessel during vibration, overturning, or bumping, and to provide a compact, robust, and highly portable water distillation device. It is something to do.

A first means of solving the problem The present invention provides a porous polytetrabufated ethylene sheet for isolating the evaporation vessel and the condensation vessel, or a waterproof treatment.
1. f: These problems are attempted to be solved by providing a membrane that is both waterproof and water vapor permeable, such as cloth.

Function: This function completely prevents the movement of unpurified water from the evaporation vessel to the condensation vessel during vibrations or rollover, and prevents contamination of distilled water due to entrainment of impurities during bumping. do. On the other hand, due to the water vapor permeability of the membrane, water generated in the evaporation vessel can easily migrate to the condensation vessel. 1. This eliminates the need for droplet collectors and bumping preventers that are included in conventional distillation equipment.
Therefore, the distillation equipment can be made smaller.

EXAMPLE Hereinafter, one practical example of the present invention will be explained in detail with reference to the drawings. FIG. 1 is a schematic cross-sectional view of a water distillation apparatus according to the present invention.

A porous polytetrafluoride ethylene resin sheet (3) is provided between the evaporation vessel (1) and the condensation vessel (2). The unpurified water supplied from the water supply port (5) is sent to the heater (4).
It is heated to become water vapor. This water vapor passes through a porous polytetrafluoride ethylene sheet [7] and is transferred to a condensing vessel.
], and a metal mesh (9) is stuffed inside. This net cools the water vapor and condenses it into water at the treetop water outlet (
7) Exit. (6) is an evaporation container gas vent port, and (8) is a condensation container gas vent port.

As described above, the present invention not only can completely prevent the movement of impurities from the evaporation vessel to the condensation vessel, but also is a compact and robust water distillation apparatus that is easily portable. 1'i
-The industrial value is extremely large.
