Description

Steam heater {steam heater}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steaming apparatus, and more particularly, to a steaming apparatus of a very preferred embodiment having a simple structure, smooth wet steam generation and high energy efficiency.

Printing a variety of patterns on fabrics (fabrics) shipped from a textile factory is called printing, and a factory that does this is called printing.

The printing operation does not end with a printing process alone, but a chamber filled with steam, specifically, a printing process, which is filled with wet steam (steam, that is, a state in which water vapor (gas state) and fine water droplets (liquid state coexist), In other words, it hangs for a certain time in the steam room.

The deposition process serves to promote the color development and fixation of the dye applied to the surface of the fabric through the printing process.

In other words, the dye on the surface of the fabric is slowly absorbed into the fabric and stabilized in the steam chamber filled with wet steam, and at the same time displays a proper color.

The steaming apparatus is a mechanical apparatus for forming and maintaining a state in which the steam is filled in the steam chamber, and a pump for supplying water into the steam chamber, a steam generator for generating steam, and a steam pipe introduced through a separate pipe. It consists of a wet steam reservoir where steam and water are combined.

Specifically describing the process of the water and the steam is joined in the wet steam reservoir, it is made by the method of blowing steam through the steam supply pipe into the water introduced through the water supply pipe filled in the wet steam reservoir.

This results in the effect of heating the water with steam, and as a result of the boiling water in the wet steam reservoir, the upper, that is, the interior of the steam chamber is always filled with wet steam.

By the way, the conventional heating apparatus and the storage chamber had a structural and fundamental problem.

First, since steam and water flow into the steam chamber through separate pipes, the overall structure is complicated and installation costs are high.

In addition, since steam supplied from the steam generator is not sprayed by the steam itself, it is introduced into the water and serves to boil the water, so that the generation of wet steam at an appropriate temperature is not smooth over time, but a large amount of high temperature superheated steam is generated. There is a problem that occurs.

The problem of inadequate moist steam generation results in a large amount of steam, which, in other words, means that energy efficiency can only be quite low.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object thereof is to provide a vapor deposition apparatus of a very preferable type having a simple structure, smooth generation of wet steam, and high energy efficiency.

In other words, it is an object of the present invention to provide a steaming apparatus capable of generating a large amount of wet steam with a small steam supply as well as a low installation cost due to its simple structure.

The object of the present invention as described above is achieved by the natural mixing of steam and water to achieve a wet steam state and at the same time to be supplied into the steam chamber.

Specifically, the steaming apparatus according to the present invention, the steam / water mixing chamber is a natural mixing of steam and water, the steam supply pipe and water supply pipe coupled to the steam / water mixing chamber inclined mutually, and the steam supply pipe in the steam / water mixing chamber And a wet steam supply pipe coupled to the opposite side and leading into the steam chamber.

Preferably, the front end of the water supply pipe is equipped with an automatically controlled valve device, which is automatically opened or closed in accordance with the temperature inside the steam chamber.

According to the structure as described above, when the steam passes through the steam / water mixing chamber at a high speed, the water in the water supply pipe is sucked into the steam / water mixing chamber due to the pressure difference is mixed to achieve a naturally wet steam state. (The pressure at the very high flow rate of steam is relatively low. (Bernui Theorem))

As a result, after the steam / water mixing chamber, the fluid in the wet steam state is supplied into the steam chamber.

In other words, in the steam generator of the present invention, the fluid flowing inside the wet steam supply pipe is a state in which hot steam (gas state) and fine water droplets (liquid state) coexist, namely, wet steam state.

According to the present invention as described above, there is obtained an effect of simplifying the structure and thereby reducing the installation cost, as well as a vapor deposition apparatus having a very desirable structure with high wet steam generation and high energy efficiency.

Specifically, the reason why the effect of simplification of the structure is obtained, as a structure in which water is naturally mixed due to the pressure difference, a separate water supply pump and a separate water supply pipe installed through the steam chamber are unnecessary.

In addition, with regard to the reason why the generation of wet steam is smooth and the energy efficiency is high, since the steam, which is a product of energy consumption, is injected into the steam itself rather than flowing into the water, a large amount of wet steam can be generated with a small steam supply amount.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will now be made in detail of the present invention according to the accompanying drawings.

1 is a view showing a steaming apparatus and a steam chamber according to an embodiment of the present invention, the fabric (W) through the printing process in a cross-sectional format of the state hanging on the hook bar (B) in the steam chamber (H) filled with wet steam. It is shown.

The steaming apparatus according to the embodiment includes a steam / water mixing chamber 30 in which natural mixing of steam and water is performed, a steam supply pipe 10 and a water supply pipe 20 coupled to the steam / water mixing chamber 30 to be inclined with each other, The steam / water mixing chamber 30 includes a wet steam supply pipe 40 coupled to the steam supply pipe opposite to the inside of the steam chamber H. (Steam generator not shown)

The water supply pipe 20 is connected to a normal water supply pipe in the factory, while the automatic control valve device 21 is mounted near the connection portion with the steam / water mixing chamber 30.

As mentioned above, the valve device 21 is automatically controlled as it is connected to a thermometer (built in a bimetallic control device) set according to the optimum internal temperature of the steam chamber H.

The control operation will be described in detail. When the internal temperature of the steam chamber H rises above an appropriate temperature (that is, when the steam supply amount is relatively large), the steam chamber is opened by supplying water by opening the valve device 21. H) While lowering the internal temperature, if the internal temperature of the steam chamber H drops below an appropriate temperature (that is, when the steam supply is relatively low), the steam is increased by closing the valve device 21 and not supplying water. Increase the temperature inside the seal (H).

As described above, the steaming apparatus of the present invention has a structural feature such that steam and water are naturally mixed to achieve a wet steam state and simultaneously supplied into the steaming chamber.

Therefore, only one steam supply pipe 40 is connected to the steam chamber H, and a plurality of through holes h3 are formed in the portion of the wet steam supply pipe 40 inserted into the steam chamber H. Wet steam is injected through (h3) to fill the interior of the steam chamber (H).

Unexplained reference numeral 41 denotes a support for supporting the tip of the wet steam supply pipe 40.

On the other hand, as time passes, the water flowing down the bottom of the steam chamber H is discharged to the outside of the steam chamber through the drain pipe (D).

FIG. 2 is an enlarged view (in the case of the first embodiment) of the A display portion on FIG. 1 to explain the internal structure of the steam / water mixing chamber 30.

According to the drawing, the steam introduced into the steam supply pipe 10 is blocked by the flow due to the side plate 1 (32) welded to the steam supply pipe 10, while a plurality of holes (h1) formed on the side wall 1 (32) ) Is sprayed at high speed. (See arrow)

Considering that the inside of the steam supply pipe 10 on the left side of the side wall 1 32 has a high pressure of about 40 atmospheres, the injection speed of the steam passing through the through hole h1 is very high.

As mentioned earlier, the pressure at the steam passage through which the flow rate is very high is relatively low. (According to Bernoulli's theorem)

The steam injected through the through-hole h1 passes through the steam / water mixing chamber 30 and exits through the other side wall, that is, through the through-hole h2 on the side wall 2 33. If the valve device (see FIG. 1) on the 20 is open, water in the water supply pipe 20 is naturally mixed toward the steam passage region having a relatively low pressure to pass through the hole h2 while forming a wet steam state. . (See arrow)

The through hole h2 is larger than the through hole h1 for smooth passage of the steam / water mixed fluid.

In the case of an Example, the diameter of the through hole h1 is 3.5 mm, the diameter of the through hole h2 is 6.5 mm, and the number is ten pieces, respectively.

In the wet steam supply pipe 40, the diameter of the through hole h3 (see FIG. 1) formed in the portion inserted into the steam chamber H is 3 mm, and the number is 20 pieces.

The other end of the steam supply pipe 10 is provided with a steam generator, but is not different from the case according to the conventional structure as well as those of ordinary skill in the related art will not be described in further detail.

Since water is naturally sucked by the pressure difference toward the steam injected at high speed, it is not necessary to install a separate feed pump at the distal end of the water supply pipe 20.

In other words, the opposite end portion of the water supply pipe 20 may be connected to a normal water supply pipe in the factory.

Unexplained reference numeral 31 denotes a cylindrical body constituting the steam / water mixing chamber 30 according to the embodiment.

Unexplained reference numeral 34 denotes a central round bar that determines the distance between the two side walls 32 and 33, and as the central round bar 34 is inserted, the space inside the steam / water mixing chamber 30 is entirely donut shaped. Will be achieved.

On the other hand, the internal space of the steam / water mixing chamber 30 is not necessarily a doughnut shape, it is also possible to have a structure as shown in Figure 3 which is another view (in the case of the second embodiment) to enlarge the A display portion of FIG.

In the structure shown in FIG. 3, the steam supply pipe 10 and the wet steam supply pipe 40 having the side walls 1 32 and the side walls 2 33 coupled to each other are provided at both side ends of the steam / water mixing chamber 30 ′. In the case where the respective insertion depth to the cylindrical body 31 is constantly managed in the engagement, the central round bar in FIG. 2 is unnecessary.

In addition, the structure shown in FIG. 4 which is another figure (in the case of 3rd Example) which enlarges and shows the A display part of FIG. 1 is also possible.

The structure shown in FIG. 4 is a case in which the inclined through-hole h4 is formed to form the steam / water supply pipe 30 "as a single member and horizontally penetrate the center portion thereof. 32, 33) become unnecessary.

In principle, the coupling between the elements constituting the heating apparatus of the present invention is by welding, but other coupling methods may be used as long as high pressure can be maintained.
