Abstract

PURPOSE: A steam generator is provided to increase the amount of humidification and shorten humidification time by suppressing convective circulation and facilitating vaporizing by using a surface tension of water. CONSTITUTION: A porous medium heater plate(3) having a shape nearly same as the cross section of a steam generating vessel and a size smaller than the size of the container, is mounted within the steam generating vessel having outlet pipes(101,101') arranged at the top surface of the steam generating vessel. A water storage chamber(102) is arranged underneath the porous medium heater plate, and a plurality of supply holes(201) are formed at constant intervals at the bottom of the water storage chamber. A supply pipe(2) having an end extended outward from the steam generating vessel and connected to a pump(31) is arranged so as to supply water into the water storage chamber. The water being supplied into the water storage chamber is prevented from flowing over the top surface of the porous medium heater plate.

Description

Steam generator using a porous heating plate {Steam generator using a porous medium heater}

The present invention relates to a water vapor generating apparatus using a porous heating plate, and more particularly, the water surface between the plurality of water holes and the water through grooves formed in the heating plate to maximize the surface tension effect between the water surface of the water stored in the water vapor generating container By heating the steam to generate steam, it is possible to obtain a steam generator that is expected to improve the heating rate of the water and reduce the power.

In general, the steam generator refers to a device that boils and vaporizes water stored in a predetermined container with a heating device.

However, water vapor generators to date have been generated by generating water by injecting one or more heating rods into the water stored in the steam generating container to heat the water.

However, such a heating device requires a long time to vaporize (vaporize) the stored water because the heat of the heating rod located in the water of the stored water is conducted by convection, that is, the heat is dispersed throughout the water. There was also a big waste of problems.

The present invention was invented with a technical problem in order to solve the problems appearing in the conventional steam generator as described above, it was conceived that the surface tension is present at the interface when the surface of the liquid and the surface of the liquid contact, It was conceived that the heating of the interface uniformly suppresses the convective flow of water and the vaporization reaction is rapid.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

A porous heating plate having a smaller size than the flat cross-sectional shape of the generating vessel 1 at a predetermined position inside a conventional steam generating vessel 1 having one or more discharge pipes 101 and 101 'on the upper surface thereof. 3) installed horizontally so that the reservoir 102 is formed at the lower side thereof, and a plurality of supply holes 201 are formed at the bottom at equal intervals in the lower portion of the reservoir 102, and one end of the generating vessel 1 It extends to the outside so that the water supply pipe (2) connected to the pump 31 can be stored in the storage chamber 102, but the water surface to be stored does not overflow the upper surface of the porous heating plate (3) .

According to the present invention, the porous heating plate 3 which is rolled out at a predetermined position inside the generating container 1 is installed horizontally with the flat cross-sectional shape of the generating container 1, but the size is smaller than that of the lower side of the porous heating plate 3. Water is stored in the reservoir 102 so as to be positioned between the upper and lower surfaces of the porous heating plate 3 so that the upper surface thereof is exposed as shown in FIG. 1 to expose the upper surface of the porous heating plate 3 as shown in FIG. 4. The surface tension portion 17, which is a surface boundary surface, is first heated to increase the heating rate of the water, that is, to generate rapid steam, and the water supplied to the reservoir 102 is supplied with a supply hole 201 formed at the bottom of the supply pipe 2; Since it is supplied downward by), even if the water is continuously replenished, the disturbance of the upper water surface due to the supply power of the water being replenished is prevented.

In addition, the water level generating unit (1) on one side of the water level detecting unit 21 is formed separately to communicate with the reservoir chamber 102 of the generating container (1) by the lower connection pipe 25 and the water level detecting unit (21) When the water level detecting electrode 23 and the water level detecting device 22 are installed to output a signal from the pump 31 to the controller 32, the water level sensor 21 is installed. Not only can it be unmanned, but its water level (the position where the water surface does not flood the top of the porous heating plate) can always be kept constant.

Water surface is formed when the plurality of heater wires 4 embedded in the porous heating plate 3 are not exposed to the water supply hole 301 and the water supply groove 302 at both ends and the center of the porous heating plate 3. The area of contact is widened so that a large amount of water vapor can be generated at once.

Therefore, in the present invention, the surface boundary surface is heated to the side of the porous heating plate 3 without the porous heating plate 3 stored therein. In other words, the convective circulation flow is suppressed using the surface tension of water and the vaporization reaction is performed. It can accelerate the humidification time, increase the amount of humidification, and anticipate the effect of sterilization and power saving.
