Description
Technical field
The utility model belongs to the power generation and heat supply device, particularly a kind of cogeneration heating system of utilizing.
Background technique
Utilize the cogeneration heat supply process to be mainly used in Medium ﹠ small size power plant, belong to advanced international level.Also can be widely used in the industries such as chemical industry, metallurgy and casting.The thermal power plant generating efficiency is very low at present, basic reason is that to be recycled the heat waste that water takes away too high, and loss is up to 50.5% to 61.5%, and the vaporization heat that discharges of the super-cooled vapor of this part loss, its temperature is far below the boiling point of water, and water has lost the meaning as heat transferring medium.Therefore, utilizing this part waste heat is the research topic that everybody extremely pays close attention to.At present both at home and abroad to cooling medium waste heat, waste vapour waste water residual heat, high-temperature product and afterheat of slags, chemical reaction waste heat, combustible exhaust gas waste liquid and high-pressure liquid overbottom pressure etc., carried out widely research, comparative maturity be cogeneration technology, the cold and hot generation technology of combustion gas distributed energy of cement kiln.For the waste heat that utilizes the thermal power plant, namely in the winter time for heating for thermal region, can utilize again cogeneration, not just can to generate electricity winter with all strength, make waste heat accomplish to utilize to greatest extent, not yet see up till now the implementation methods that a kind of the best is arranged.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, no matter provide a kind of in what season, that can give full play to waste heat effect utilizes the cogeneration heating system.
The technological scheme that the utility model technical solution problem adopts is: a kind of waste heat that utilizes is sent out
The electricity heating system, comprise steam turbine, temperature-decreased pressure reducer and vapour condenser, it is characterized in that filling an absorption heat pump between vapour condenser and hot user, valve nine is equipped with in being connected between a screw rod generator in parallel between absorption heat pump and hot user, absorption heat pump and vapour condenser on inlet pipeline; Valve one and valve two are housed on the admission passage between absorption heat pump and steam turbine; On inlet pipeline between absorption heat pump and screw rod generator, valve seven is housed, valve six is housed on rising pipe.
The beneficial effects of the utility model are: this model utility can take full advantage of waste heat, can round-the-clockly utilize throughout the year, and is widely applicable, and UTILIZATION OF VESIDUAL HEAT IN efficient is high.
