（産業上の利用分野）
本発明は、天然蒸気型地熱発電プラントにおいて、産出

いるが、閉塞の懸念もあり余り普及していない。(Prior Art) Conventionally, it has been known that during geothermal power generation, fine dust in natural geothermal steam, particularly superheated steam, sticks to turbine nozzles and turbine blades, causing a rapid decrease in turbine output. Therefore, as a method for removing dust from steam, a dust cyclone is used. However, since it is insufficient to remove fine dust, multi-cyclones are used as small cyclones, but they are not widely used due to concerns about blockages.

することを目的とする。(Problem to be solved by the invention) Originally, the principle of dust removal using a cyclone type was to create a swirling flow in the gas and apply centrifugal force to the dust to separate it. The separation limit particle size is determined by the cyclone barrel diameter, so it is several μm-
For ultrafine dust of several micrometers, it is essential to use a small cyclone, and if a large amount of steam is to be processed, a multi-cyclone must be used. However, fine dust is sticky and adheres to the inner surfaces of many cyclones, crevices, and everywhere else, requiring frequent maintenance, and in the worst case scenario, there is a risk that the system will become clogged and unusable, so this is not a universal method. On the other hand, louver type dry separators utilize the inertia of dust, and although their separation ability depends on the particle size, density, flow rate, and shape of obstacles, they are actually inferior to cyclones. The separation limit is a particle size of several tens of micrometers or more, and removal is insufficient. The present invention was devised in view of the current situation, and provides a geothermal steam cleaning method that minimizes energy loss, uses simple wet equipment, and enables long-term stable operation of turbines. The purpose is to provide.

要がある。a) Steam cleaning with water in spray salt for steam cleaning This is the biggest difference from conventional dry dust removal. The steam passing through the spray salt must be uniformly sprinkled with water using a suitable watering mechanism, so that the steam must pass through a water filter, such as a multi-stage spray device or a water mist generator.

速等により行うことができる。The characteristics of steam produced from production wells differ in each thermal field, with some steam having a high degree of superheating and some steam having a low degree of superheating. When the degree of superheating is high, in order to perform steam cleaning in the next step under substantially constant equilibrium conditions, it is necessary to reduce the temperature in advance and control the degree of superheating to keep the steam temperature constant. When using water injection, the temperature can be controlled by the amount of water, and when using heat exchange, the temperature can be controlled by the flow rate of water.

までもない。The above explanation has been given in the main structural order of the invention, but if described along the flow of steam, the order would be temperature reduction by water injection, cleaning spray, mist separator, etc.
Spray water circulation and waste heat recovery are not related to the main stream of the line, but are measures to minimize energy loss. Further, in the present invention, "water" is used in the meaning of liquid in the steam cleaning spray tower, and is usually pressurized hot water. Incidentally, the embodiment described below is only one embodiment of the present invention, and it goes without saying that the temperature, pressure, and various equipment matters are not limited to this embodiment.

沿って説明する。(Example) An example of the cleaning method according to the present invention will be described in FIG. 1 along the flow of steam.

ように配慮した。Steam (approximately 190°C) from the production well 1 is transferred through the steam line 2, and the steam temperature is controlled to a predetermined temperature (163°C) at the humidifying water injector 3, and then to the steam cleaning spray tower. 4 will be introduced. The spray tower is equipped with a water filter such as a multi-stage spray device, a water mist, and a water column, so that most of the fine dust adheres to the surface of the hot water droplets and is removed. The treated steam was further introduced into the mist separator 5, where the mist was separated and steam with a dryness of about 99.99% was obtained. This steam was finally supplied to the turbine 9 as steam at about 150°C. The spray tower for steam cleaning is equipped with a spray water circulation pump 7 to circulate and use high-temperature water (approximately 150°C in a pressurized state) to prevent the temperature of the steam from lowering unnecessarily. .

Heat was exchanged with the water from the water supply pump 8 (using water from the condenser), and the temperature of the make-up water was raised by about 20°C.

。Above, we have described the treatment method from production well 1 to turbine 9 for one system, but in actual equipment, in the treatment of 200 T/h produced from the steam generation group, 2
It is divided into systems and operated at each LOOT/h. By adopting the method of the present invention, an output reduction of approximately 5%/month due to scaling of turbine nozzles and turbine blades can be reduced to 1%.
It became possible to reduce the number to 74 or less. Incidentally, while the dust removal rate using the conventional dust cyclone is approximately 42%, the method of the present invention achieves a result of 98% or more. Figure 2 shows the results of a demonstration experiment of the method of the present invention on a steam treatment line with a capacity of 115 T/h, and shows the numerical values when Na''K'' was used as a tracer. The figures show the values when SS (insoluble component) is used, and it can be seen that the dust in the steam becomes almost O by the method of the present invention.

増量も見込まれるので、エネルギー損失は殆んどない。"Effects of the Invention" As explained in detail above, when the method of the present invention is used to purify geothermal steam, almost the entire amount of it, including ultrafine dust of several micrometers, contained in the steam can be removed. Since dust can be removed, it is possible to operate the turbine stably for a long period of time, and it is possible to prevent a decrease in output caused by dust adhering to the turbine nozzle and turbine blades. Also, compared to conventional multi-cyclone or louver type dry separators, there is no danger of dust clogging the internal surfaces or gaps of the device, or various troubles due to incomplete capture of ultrafine particles. , maintenance becomes extremely easy. Furthermore, the reduction in the specific enthalpy of steam due to water injection or spraying, which is of greatest concern in the present invention, can be minimized by circulating water for water injection through heat exchange with heat drainage or heated spray water for make-up water. It is possible to do this, and a slight increase in the amount of steam can be expected due to water injection, etc., so there is almost no energy loss.

きる。Moreover, the amount of dissolved oxygen can be maintained to a minimum due to the water circulation as described above, so the method of the present invention can be said to be an excellent steam cleaning method from the standpoint of equipment maintenance.
