Abstract
The utility model discloses a raw water heating system using waste steam of a direct air-cooling turbine for heating. The raw water heating system comprises a raw water heater and an auxiliary steam pipeline which is connected with a steam inlet of the raw water heater, and a gate valve is arranged on the auxiliary steam pipeline. The raw water heating system further comprises a turbine, a U-shaped water seal and a steam exhaust device. The raw water heating system has the advantages that only waste steam and exhaust steam of the turbine are utilized as a heat source for heating raw water, waste heat of the exhaust steam is utilized, energy of back-heating and steam extraction is saved, power generating efficiency of the turbine is promoted, and meanwhile due to the fact that temperature of the heating steam source is reduced, scaling tendency of the heater is eliminated.
Description
Technical field
The utility model relates to a kind of raw water heating system, particularly relates to a kind of raw water heating system that utilizes direct air-cooling turbine exhaust steam heating.
Background technique
The unboiled water temperature that power plant chemistry water processed need to be supplied is about 30 degree, but the unboiled water temperature is generally in 10-20 degree left and right, so need heating; At present, unboiled water heating in thermal power plant adopts the station-service auxiliary steam by face formula heat exchanger or mixed heat exchanger heating always.
Prior art heating unboiled water is to adopt low pressure steam to heat by heat exchanger, consumes steam and the energy, affects generated energy; And unboiled water hardness is high, and the low pressure steam temperature is high, and the heater tube side has fouling tendency; For direct air-cooling turbine, unboiled water temperature 10 high due to exhaust pressure, that the steam discharge saturation temperature need to be supplied higher than power plant chemistry water processed can satisfy unboiled water with turbine discharge and add heat request more than spending.
The model utility content
The purpose of this utility model is to provide a kind of raw water heating system that utilizes direct air-cooling turbine exhaust steam heating.
the purpose of this utility model is implemented by following technological scheme, a kind of raw water heating system that utilizes direct air-cooling turbine exhaust steam heating, it comprises raw water heater and the auxiliary steam pipeline that is connected with the steam inlet of described raw water heater, described auxiliary steam pipeline is provided with gate valve, it also includes steam turbine, U-shaped water seal and steam exhaust device, the steam (vapor) outlet of described steam turbine is connected with the steam inlet pipeline of described steam exhaust device, the steam (vapor) outlet of described steam exhaust device is connected with the steam inlet of described raw water heater by pipeline, the pipeline that connects the steam inlet of the steam (vapor) outlet of described steam exhaust device and described raw water heater is provided with described gate valve, the outlet port of described raw water heater is provided with described gate valve and described U-shaped water seal, the outlet of described raw water heater is connected with the entrance of described U-shaped water seal, the outlet of described U-shaped water seal is connected with hot well pipeline in described steam exhaust device.
The utility model has the advantage of, all utilize the steam discharge exhaust steam of steam turbine as the thermal source of heating unboiled water, utilized the exhausted spare heat of steam turbine; Save the energy of regenerative steam, improved steam turbine power generation power; Owing to having reduced the temperature that adds hot vapour source, eliminated the fouling tendency of heater simultaneously.
