一种背压机供热、储能系统
摘要：
本实用新型一种背压机供热、储能系统涉及的是一种热电厂的供热储能系统，尤其是一种背压机供热蒸汽加后置背压机储能系统。包括背压机供热子系统和储能子系统；所述背压机供热子系统包括锅炉、供热背压机、汽动泵小汽机、低压除氧器、给水泵、备用给水泵、高压加热器、连续排污扩容器、定期排污扩容器和减温减压器；所述储能子系统包括储能背压机、冷水箱、热水箱、汽水加热器和给水自动控制器、热水泵、冷水泵；在热负荷低谷时，供热背压机的多余供热量通过本储能系统，储存在热水箱中；在热负荷高峰时，进入供热背压机回热系统的给水为热水箱中的热水，减少供热背压机排汽加热回热系统的蒸汽用量，增加对外供热量。
摘要（英）：

The utility model relates to a that heat supply of backpressure machine, energy storage system relates to is the heat supply energy storage system of a steam power plant, and especially a backpressure machine heat supply steam adds rearmounted backpressure machine energy storage system. Including backpressure machine heat supply subsystem and energy storage subsystem, backpressure machine heat supply subsystem includes boiler, heat supply backpressure machine, the little steam turbine of pneumatic pump, low pressure oxygen -eliminating device, water -feeding pump, auxiliary feed water pump, high pressure feed water heater, continuous blowdown flash vessel, periodical blowdown flash vessel and subtracts the temperature -decreased pressure reducer, the energy storage subsystem includes energy storage backpressure machine, cold water storage cistern, hot -water tank, vapour water heater and feedwater automatic control, heat -exchanger pump, cold water pump, when the heating load low ebb, the unnecessary heating load of heat supply backpressure machine is stored in the hot -water tank through this energy storage system, when the heating load peak, the feedwater that gets into heat supply backpressure machine heat regenerative system is the hot water in the hot -water tank, reduces the steam quantity of heat supply backpressure machine steam extraction heating heat regenerative system, increases external heating load.
