Disclosed is a scale deposition testing device capable of evaluating the deposition state of scale in consideration of the influence of retention time of geothermal water generated in an actual geothermal power plant. The scale deposition testing device is provided with a plurality of scale deposition containers (17, 27), retention units (15, 25), a measurement means (T11, T12, F11, P11-P16, T21, T22, F21, P21-P26), a recording unit, and at least one of a chemical injector (13, 23), a pump (14, 24), or a heat exchanger (18, 28). The plurality of scale deposition containers (17, 27) are filled with particulate matter. The hot water supply means causes hot water to flow through each of the scale deposition containers. The retention units (15, 25) retain the flowing hot water therein. The chemical injector (13, 23), pump (14, 24), or heat exchanger (18, 28) can change at least one characteristic of the hot water, for example the flow rate, temperature, pressure or chemical composition. The measurement means can measure at least one of the flow rate, temperature, and pressure of the hot water flowing through each of the scale deposition containers (17, 27). The measurement means may be in the form of a temperature sensor (T11, T12, T21, T22), a pressure sensor (P11-P16, P21-P26) or a flow sensor (F11, F21). The recording unit receives data from the measurement means. The retention units (15, 25) are each configured to be able to change the retention time of the hot water, this may be achieved by reducing the volume of hot water contained in the retention units by the addition of a heat resistant material. The heat resistant material may be polytetrafluoroethylene balls. |
