  However, the geothermal steam water heater simply heats the water circulating in the pipe using geothermal steam, including silica, calcium ions, magnesium ions, iron ions, manganese ions contained in the geothermal steam. , Mineral components such as bicarbonate ions are not directly affected.

  In addition to the geothermal steam water heater, there is a geothermal power plant that uses geothermal steam, but this also simply uses geothermal heat, and various mineral components contained in the geothermal steam are not effectively utilized. .

  The present invention was devised in view of the above points, and it is possible to obtain hot spring mud containing various mineral components by exposing and melting high-quality clay with geothermal steam. The object is to provide a manufacturing method.

  In order to achieve the above object, a method for producing hot spring mud using geothermal steam according to the present invention includes a step of collecting geothermal steam, a step of dissolving clay by exposing clay to the collected geothermal steam, and the dissolution Filtering the clay.

  Here, by spraying the geothermal steam collected from the geothermal steam sampling well onto the solid clay for a long time, the clay is dissolved in fine particles by steam at around 100 degrees and exposed to geothermal steam containing a lot of hot spring components. As a result, hot spring components adhere to each fine particle. The entire clay is fluidized by the moisture contained in the geothermal steam, and high quality hot spring mud can be obtained by removing contaminants such as pebbles, sand and vegetation from the fluid clay.

  As described above, according to the present invention, hot spring mud having the same composition as natural hot spring mud can be produced in large quantities by effectively utilizing geothermal steam and exposing clay produced in large quantities to geothermal steam. It becomes.

  In addition, hot spring mud dissolved by geothermal steam is generated in a wild environment (environment containing impurities such as rainwater, garbage, stones, sand, vegetation, etc.) by filtering further in an environment free of impurities. Compared with the hot spring mud, it is possible to obtain a high-quality, hygienic and high-quality hot spring mud.

Hereinafter, embodiments of the present invention will be described with reference to the drawings to provide an understanding of the present invention.
FIG. 1 is a schematic explanatory diagram showing an example of a method for producing hot spring mud using geothermal steam to which the present invention is applied.

  Here, in order to effectively use the geothermal steam, boring is carried out in the ground where the geothermal steam is present, the metal pipe 1 is mounted, and the geothermal steam 2 is guided from the metal pipe 1 into the treatment tank 3. This geothermal steam 2 is high-temperature steam at around 100 degrees containing hot spring components.

  Further, clay 4 is put into the treatment tank 3. This clay 4 is a mineral solid clay, and natural clay collected from the formation contains impurities such as pebbles, sand and vegetation and various germs in the soil.

  Also, a hot spring mud outlet 5 is provided at the bottom of the treatment tank 3 and an exhaust port 6 is provided at the top so that the inside of the treatment tank 3 does not become high pressure.

  Therefore, the clay 4 put into the treatment tank 3 is exposed to the high-temperature geothermal steam 2 around 100 degrees, so that the surface is gradually aged to hot spring mud by the high-temperature moisture contained in the geothermal steam 2. Go.

  Therefore, clay is decomposed into fine particles by geothermal steam, and immersed in the hot spring components, the surface of each fine particle constituting the clay, including silica contained in geothermal steam, calcium ions, magnesium ions, iron ions, manganese Hot spring components such as ions and bicarbonate ions will adhere.

If there is a lot of moisture contained in the geothermal steam, it can be used as it is, but if the moisture is low, mudification of solid clay is promoted by adding geothermal steam with hot springs added in advance in the treatment tank. Aging is also accelerated.
Moreover, it becomes more efficient to provide the lid 7 in the treatment tank 3 in order to accelerate the aging.

Next, as shown in FIG. 2, by continuing to inject the geothermal steam 2 into the treatment tank 3 for about 24 hours or more, the clay melts and circulates and fluidizes so that a large amount of hot spring components are contained in the clay particles. Along with the hot spring mud 8 that is contained, the germs in the clay are killed by the fumarole around 100 degrees.
In addition, when the hot spring mud overflows due to moisture due to geothermal steam, it is taken out from the discharge port 9 and collected in another tank.

  The hot spring mud aged in this way is taken out from the hot spring mud take-out port 5 as shown in FIG.

  Next, in the filtration step, filtration is performed roughly in three stages using a filter 10 composed of a sieve having a fine mesh as shown in FIG.

  Here, the filtration must be performed in a hot state, that is, in a fluidized state, as shown in FIG. Therefore, the hot spring mud in a fluidized state is filtered through three stages of filter 10A, filter 10B, and filter 10C with the mesh coarseness reduced successively. Then, the filter 10B removes sand and the like that could not be removed by the filter 10A, further removes foreign matters such as fine sand, and the hot spring mud with very fine clay particles is filtered as a finished product.

  The hot spring mud produced in this way is liquid, semi-solid by removing water to some extent, or hot spring mud is completely dried and stirred to form powder depending on the application.

In the present embodiment, the geothermal steam is sampled by drilling into the ground. However, for example, the geothermal steam may be naturally blown from the ground, and in this case, the geothermal steam is collected by a pipe or the like from the ground surface.
The pipe is not necessarily a metal pipe, and may be a pipe made of any material as long as it has a rust-proof and heat-resistant effect, such as a vinyl chloride pipe or a clay pipe.

Furthermore, in this embodiment, the geothermal steam is taken in from the upper part of the treatment tank to dissolve the clay, but for example, a method of aging the clay by taking in the geothermal steam from the lower part of the treatment tank can be considered, and the temperature and pressure of the geothermal steam are considered. It is desirable to adopt the most suitable method considering the above.
Moreover, it is not always necessary to use a sieve for the filter, and any filter having any mechanism may be used as long as it can filter the molten mud in a high temperature state.

  The types of spring quality of geothermal steam include sulfur springs, acidic springs, radioactive springs, carbon dioxide springs, chloride springs, sulfur salt springs, bicarbonate springs, and iron wires. It is possible to produce hot spring mud with different efficacy, such as those having a therapeutic effect on atopic dermatitis, or those suitable as bathing agents.

  Clay minerals can be divided into three groups: crystalline silicates, amorphous silicates, and oxidized / hydrated minerals. Furthermore, when the soil clay is analyzed, most of it is occupied by crystalline silicate. This is because the silicic acid tetrahedron formed by one silicon atom entering the gap in the middle of the triangular pyramid formed by four oxygen atoms forms a layer, and the layer and aluminum or magnesium are the center. It is a mineral that is stacked in a sandwich with another layer, and is named such as halloysite, kaolinite, smectite, vermiculite and chlorite depending on the type and arrangement of atoms in this layer.

  These clays are excellent in swelling properties. This swelling is a phenomenon in which a fine solid substance takes in liquid and increases its volume, and in the process where solid clay is dissolved by geothermal steam, it contains a lot of spring quality, but the liquid takes in fine particles that make up the clay Will be.

In addition, clay has a strong adsorptivity, and by using the hot spring mud of the present invention for facial cleansing, shampoo, etc., the fine particles enter the pores on the skin surface and adsorb dirt, or the spring quality contained in the fine particles It has a medical effect to treat beauty and atopic dermatitis.
Therefore, by making the hot spring mud into a liquid or cream form, it can be used for beauty packs, mud bathing agents, facial washes and shampoos.

Also, the filtered liquid hot spring mud is completely dried and further stirred (ground) to form a powder, so that each fine particle contains only various mineral components that are hot spring components. By putting the hot spring mud powder into a home bath, the hot spring quality contained in the hot spring mud powder elutes in the hot water, making it possible to create a natural hot spring.
Therefore, it is possible to enjoy hot springs in various places by producing hot spring mud using geothermal steam in each hot spring area.
