Abstract
The utility model relates to an ORC screw rod expansion power generation system driven by yellow phosphorus tail gas burning steam. Yellow phosphorus tail gas (14) is led into a gas-fired boiler (2) for burning through a lead-in device (1), and generated steam enters into a reducing valve (17) and a pressure regulating valve (4) through a tee joint (16) along a steam pipe (3) respectively. The regulating valve (4) adjusts according to working pressure and temperature of an ORC expansion machine (5). The steam enters into the ORC screw rod expansion machine (5) and drives a generator (6) to generate electricity, and electric power is outputted through a power transmission line (7). According to the ORC screw rod expansion power generation system driven by the yellow phosphorus tail gas burning steam, for a yellow phosphorus enterprise which purchases the gas-fired boiler, only a set of ORC screw rod expansion power generation system driven by the steam needs to be purchased so as to achieve electricity generation by burning the yellow phosphorus tail gas. Utilization rate of the gas-fired boiler is improved, investment in an early stage is reduced, and cost is further reduced as the tee joint (16) is used for distributing the steam.
