Problems solved by technology
When the inlet water temperature is less than or equal to 15°C, the vacuum pump meets or exceeds the design requirements. When the working water temperature increases, the vacuum degree of the vacuum pump cannot meet the design requirements, and the output of the vacuum pump will drop significantly, directly affecting the vacuum degree of the condenser. , so that the economic benefits of the steam turbine generator set are reduced

The invention relates to a control system for reducing temperature and saving energy of operating water of a vacuum pump, comprising a refrigeration cycle system, an external cycle system, an electric control, a rack and a cover; the control system is characterized by being provided with a set or a plurality of sets of parallel refrigeration cycle systems, an internal cycle system and an operating water system; the internal cycle system consists of an evaporator, a water pump, an expansible water tank, an exhaust valve, a water heat exchanger and a water pipe; the operating water system consists of a water heat exchanger, an exhaust valve, an operating water inlet pipe and a water outlet pipe, and is connected with the vacuum pump; and the internal cycle system shares one evaporator for heat exchange with the refrigeration cycle system and shares one water heat exchanger for heat exchange with the operating water system.
Description
(1) Technical field: [0001] The invention relates to power generation auxiliary equipment, in particular to an energy-saving control system for cooling the working water of the vacuum pump, increasing the output of the vacuum pump, and achieving energy-saving control. (2) Technical background: [0002] At present, the inlet water temperature of vacuum pumps in domestic power plants is generally higher than the design and calibration temperature of vacuum pumps, and the inlet water temperature is mostly higher than 33°C. Normally, the design inlet temperature of vacuum pumps is 15°C. When the inlet water temperature is less than or equal to 15°C, the vacuum pump meets or exceeds the design requirements. When the working water temperature increases, the vacuum degree of the vacuum pump cannot meet the design requirements, and the output of the vacuum pump will drop significantly, directly affecting the vacuum degree of the condenser. , so that the economic benefit of the turbo...
