Abstract
The invention discloses a solar electric steam boiler and belongs to the field of solar energy application. An existing electric steam boiler is convenient to use, but consumes too much electricity. The technology is the integrated application of a solar thermal collector and an electric steam boiler. The solar electric steam boiler is characterized in that after water is heated through the solar thermal collector (1), the water is conveyed to an evaporator (3) through a water pump (2) and evaporated to be low-temperature steam, and the low-temperature steam is injected into the electric steam boiler (5) through a steam pump (4) and heated to be high-temperature steam. The solar thermal collector heats water, the water is evaporated and vaporized to be the water steam containing a large amount of latent heat of vaporization, the latent heat of vaporization of the water is 540 calories per gram, heat energy, obtained in the solar thermal collector, of the water is a few times the heat energy obtained in the electric steam boiler, heat energy is obtained through the cheap and efficient solar thermal collector, the cost of electricity is more than that of heat energy a dozen times, and obvious economic benefits are achieved. The solar energy is fully utilized, electricity is saved, the steam production cost is greatly reduced, and enterprises can obtain more profits.
Description
Technical field
The present invention is solar-electricity steam boiler, belongs to Application of Solar Energy field.
Background technology
Conventional steam boiler has fueled steam boiler and electric steam boiler, and these two kinds of equipment are all highly energy-consumings.Fueled steam boiler also has high pollution except highly energy-consuming, and in the discharge of especially coal-burning boiler, particle is many, and pernicious gas is many, and environmental pollution is larger.Thus in a lot of down town, restriction uses, and adopts electric steam boiler to replace.As hospital, hotel etc. are electricity consumption steam boiler all.But the too power consumption of electric steam boiler, causes entreprise cost to increase, benefit reduces.Some enterprises solar thermal collector is heated to nearly Baidu water from normal temperature, with water pump, hot water is injected electric steam boiler, but, water is heated to 100 degree from normal temperature 20 degree and enters boiler, every 1 gram of water only sees in the heat of 80 cards, compare with the heat energy of hundreds of card needed for every 1 gram of high-temperature steam, the contribution of solar energy is too little, is not widely applied.
Summary of the invention: object of the present invention, is to utilize solar thermal collector to provide most heat energy for electric steam boiler, to save electric energy, increases economic efficiency.
Its technical scheme is: by solar thermal collector and electric steam boiler organically Integrated predict model, with solar thermal collector, heat vaporized for the water water vapour become containing a large amount of latent heat of vaporization is entered electric steam boiler; Near electric steam boiler, arrange solar thermal collector, with solar thermal collector, water is heated, with heat-exchanger pump, hot water is delivered to evaporimeter, carburation by evaporation becomes Low Temperature Steam; With heat pump, Low Temperature Steam is injected electric steam boiler; Become high-temperature steam with the supercharging of electric energy heat temperature raising, high-temperature steam is delivered to through pipeline and is used vapour field; Intake pump is to solar thermal collector moisturizing.
Solar thermal collector is utilized water to be heated the Low Temperature Steam become containing a large amount of latent heat of vaporization, Low Temperature Steam enters electric steam boiler and is heated as high-temperature steam again, the latent heat of vaporization of water is every gram 540 card, the heat energy that water obtains at solar thermal collector is than many several times that provide in electric steam boiler, the cost of heat energy is obtained less than 1/10th of the cost of electric energy with solar energy, this just makes full use of the effective using electricity wisely of solar energy, greatly reduces the production cost of enterprise.
