Abstract
The invention discloses an off-peak electricity high-temperature heat-storage steam generating system comprising a heat storage tank. High-temperature heat storage bricks and a phase change molten salt ball are arranged at the center of the heat storage tank. The lateral wall of the heat storage tank is provided with an inlet and an outlet which are respectively connected with a heat-conduction medium heating pipeline connected with an electric boiler and high-temperature circulating pumps. High-temperature heat conduction oil or molten salt is heated in the electric boiler and delivered to the heat storage tank through the heat-conduction medium heating pipeline. The inlet and the outlet in the lateral wall of the heat storage tank are further connected to a plate heat exchanger provided with a cooling water inlet and a hot water outlet. By conducting heat through the high-temperature heat conduction oil or the molten salt, high-temperature heat is stored in the high-temperature heat storage bricks or the phase change molten salt ball and heated to above 300 DEG C. The off-peak electricity high-temperature heat-storage steam generating system can release heat in peak time of electricity during a daytime, and high-temperature steam generated commutatively from the heat exchanger is provided for using of production process or is fed to a steam turbine generator.
Description
Technical field
The present invention relates to the accumulation of heat power field, specifically belong to low ebb electricity high-temperature heat accumulation steam generating system.
Background technology
The accumulation of heat steam generating system is that electric energy is converted into heat-storing material heat energy, heat-storing material carries out heat exchange with water again, water is heated to the hot water of pressure or a kind of heat power equipment of steam. it need not burner hearth, flue and chimney, also need not the place of storage of fuels, greatly reduced the pollution that conventional suspicion coal burning boiler brings.The heat storage capacity of heat storage medium of the prior art is bad, and the high-temperature heat accumulation temperature is low.Can realize that coal changes electric product or replaces hydroenergy storage station.
Summary of the invention
The purpose of this invention is to provide a kind of low ebb electricity high-temperature heat accumulation steam generating system, by high temperature heat conductive oil or fused salt heat conduction, heat of high temperature is stored in high-temperature heat-storage brick or phase transformation fuse salt spheroid, more than the high-temperature heat accumulation to 300 ℃.Electric power release heat peak period produces high-temperature steam by the heat exchanger exchange and uses or connect steam turbine power generation for production technology by day.
Technical scheme of the present invention is as follows:
Low ebb electricity low ebb electricity high-temperature heat accumulation steam generating system, include heat storage tank, be provided with high-temperature heat-storage brick or phase transformation fuse salt spheroid in the middle of the heat storage tank inner chamber, have import on the heat storage tank sidewall, outlet, import, outlet is connected with heat-conducting medium heating conveyance conduit respectively, be connected with electric boiler on the heat-conducting medium heating conveyance conduit, the high temperature circulation pump, high temperature heat conductive oil or fused salt heat the back and are input to heat storage tank by heat-conducting medium heating conveyance conduit in electric boiler, the import of heat storage tank sidewall, outlet is also connected to plate type heat exchanger, and plate type heat exchanger has cooling water inlet, steam (vapor) outlet.
