Scale adhesion preventing method for terrestrial power generating facility
专利汇可以提供Scale adhesion preventing method for terrestrial power generating facility专利检索，专利查询，专利分析的服务。并且PURPOSE: To prevent adhesion of scales by separating H
2 S from the gas jetted from a terrestrial heat well together with steam and hot water, allowing gas chiefly containing CO
2 to be absorbed in the hot water exhausted from a power station, and maintaining the pH at 4-6.
CONSTITUTION: Power generation is made through utilization of steam 2 and hot water 3 from a terrestrial heat fluid output by a terrestrial heat well 1, wherein a condensative gas 4 gets rid of H
2 S at a PSA tower 5 through adsorptive separation, and this H
2 S adsorbed to an adsorbent is reseparated by decompressing the PSA tower 5 and released through another system 6. Gas chiefly containing CO
2 with no H
2 S included is sent from the outlet 7 of PSA tower to the lower part of an exhaust gas absorbing tower 8, while from its upper part, the untreated hot water 3 exhausted from the power station is supplied in the form of shower, and the hot water after absorption of coal dioxide gas is taken out as treated hot water 11 from the lower part of the exhaust gas absorbing tower 8, where the pH sinks to 4-6. After contact treatment with exhaust gas 10 in a gathering tank 9, this treated hot water 11 is sent to a reductive well 12 or a hot water utilization source 13. Thus scale adhesion can be prevented at a low treatment cost.
