PAIR PREPARATIONS

The utility model relates to the field of power engineering, and more specifically, to devices that prepare a natural geothermal steam-water mixture (EMU) for use, for example, in a cycle of geothermal power plants (GeoEO).

A well-known geothermal steam preparation system containing a multi-stage direct coyat evaporator of the {type} connected to a geothermal source and to a device for generating electricity, for example, a turbogenerator (see, for example, US Pat. No. 3,953,972 to CL 60-641 for 1976 g ").

The disadvantages of the known devices include the direct contact of a multi-stage evaporator with a geotherm, the content is: mineralization of alkali, which leads to deterioration of the evaporator’s hardening characteristics due to the formation of mineral-forming elements on its surfaces.

The most technical solution to the proposed technical essence and the achieved effect is a steam preparation system containing connected pipelines 1 / and with shazhiau, a water-steam separator, a squash connected to the outlet vly, a turbine with an electric generator and a device for returning the spent steam to the well (see, for example, SJ patent J 4558568 under CL 60-641.5 for 1985). Meat system. The objective of this utility model is to eliminate the above drawbacks and increase the eco-efficiency of the glass by removing part of the heat energy of the separatum while increasing the reliability of the GeoES. The problem is solved due to the fact that in the well-known steam preparation system containing production CIша; “ШИЗ pipelines for conveying HSS, separators of the first and second stages, expander, piping, filling pumps, rinsing pumps and rhein; 1. injection well, according to the proposed utility model, piping for transportation The air defense system is equipped with an adjustable element shush, separators of the first and second stages are informed of the bypass of the SHZh steam pipeline, the surface area of which provides partial steam compensation after the first stage of the separator, shugloglupzhtel svyazagzh expander and to the input of the injection pumps, outputs of which are communicated with the reinjection well bore, wherein the outputs of the expander and muffler podklyuche.ny dopolnzhtelno to tehnologicheokshl GeoZS systems. Improving the cycle efficiency is ensured due to the fact that the outputs of the expander and the control unit are connected to a general station auxiliary system (heating, ventilation, drinking water preparation, etc.) and technologically 1 W1 station system (pumping out non-condensing gases, e; logical protection, etc. .) which makes it possible to use the heat energy of the condensate and condensate without external sources of energy. The increase in the reliability of the GeoPP is due to the fact that the air supply pipeline for the transportation of air defense is equipped with a control element that allows one while maintaining the required input harakteristsh VOP in the training pair obespechhshat work produzstivnoy S1sha; emn-sh in optshu-cial rezhzhe. In addition to TOG9, the implementation of bypass pipelines between the separator tubes 1 and 1 of the first and second stages with a surface area that provides partial condensation / of the first steam segregated in the first stage due to convective cooling of the bypass pipelines, allows reducing cohesive ducts in the transported pair / causing -2yaak: sh1ei and obliteration on the inner surfaces of the systegge elements, which increases the reliability of the latter.

Figure 1 schematically shows the proposed steam preparation system, comprising a production squash I, an air defense pipeline 2 with a regulating element 3, a first stage separator 4, a second stage separator 5 connected by a bypass pipe 6, made in accordance with the ratio "() (L. The steam output of the separator 5 is connected by a steam pipeline 7 to a turbogenerator (not shown in the drawing) .The separator 4 and 5 outputs are connected to the input of the expander / chitel 8 of the pipe Ivsh: 9. One of the outputs of the expander 8 is connected by a pipe 10 to the technol Gscheshzhzh systems of the stanchash (not shown in the drawing), the individual outputs of which, as well as the output of the expander 8, the pipe 13 is connected to the input of the injection pumps 14 into the reheat squash 15. The pipe 16 is connected to the pipe 16 of the general station systems (not shown below) ,

The device works as follows; way.

Air defense from a productive well} k.ina I through a pipeline 2 with registers a control element 3, supports; 1 szhva1oshch & t1 required air defense paratuture, enters the separator 4 of the first stage. Steam from the separator 4 is fed to the separator 5 of the second stage, from where it is led through the pipe 7 to the Typ6oycTaHOBKaivi. Double steam separation provides saturated steam with a pressure of 0.8 Sha, a degree of dryness of at least 0.999 and a salinity of less than

Img / kg. The separator from separators 4 and 5 enters the expander 8, generating steam with a pressure of 0.4 Sha for the operation of ejectors, pumping out 71 non-condensing leaning gases. Discharges of auxiliary geothermal systems and discharges of surplus hot steam and separates in transition through the pipeline

II enter the silencer 12, from where, together with the codensate from expander 8, they are partially sent via pipe 7 / line 16 to the station heating (heating and snow melting system), and mainly they are fed to the inlet of the pumps 14 for re-injection of the separat into re-injection well 15.

h. / Some of the non-condensable gases (mainly hydrogen sulfide) dissolves in the codensate under the action of an environmental protection system (not shown in the drawing) and is sent to Pump 14 into well 15, and the remaining part through a twenty-jug tube of sluglogsppppl 12 to the atmosphere.
