Steam characteristics automatic measuring device and geothermal power-generating device

摘要

Provided is a steam characteristics automatic measuring device capable of automatically, ideally also continuously measuring the characteristics of steam taken from a production well, without being affected by interfering components, such as hydrogen sulfide gas and carbon dioxide gas contained in large quantities in steam taken from under the ground, which enables the operator to continuously understand the characteristics of steam and support a smooth operation of a geothermal power plant. The device has a silica monitor for measuring a concentration of silica included in a condensate obtained by cooling steam taken from under the ground; an electrical conductivity meter for automatically measuring the electrical conductivity thereof; a pH meter for automatically measuring the pH value thereof; and a data processing transmitter for automatically transmitting data measured by each of the monitor and meters. A geothermal power-generating device equipped with the steam characteristics automatic measuring device is also provided.

主权项

1. A steam characteristics automatic measuring device comprising:
a silica monitor for measuring a concentration of silica included in a condensate obtained by cooling steam taken out from under the ground, wherein the steam is divided into non-condensable gas and the condensate by the cooling; an electrical conductivity meter for automatically measuring an electrical conductivity of the condensate; an automatic non-condensable gas flowmeter for automatically and continuously measuring a flow rate of the non-condensable gas comprising a thermometer for measuring a temperature of the condensate; a level detector for detecting a liquid level of the condensate and for outputting a lowest level-detecting signal when the liquid level falls to a lowest level and outputting a highest level-detecting signal when the liquid level rises to a highest level; a processor for calculating a flow rate of saturated dissolved gas in the condensate based on the temperature, wherein the processor calculates a total flow rate of the non-condensable gas and the dissolved gas by adding the flow rate of non-condensable gas to the flow rate of saturated dissolved gas; and a data processing transmitter for automatically transmitting data measured by each of the silica monitor, the electrical conductivity meter and data corresponding to the total flow rate calculated by the processor.
