Abstract

The invention relates to a solar energy/ composite energy closed circulating phase-change heat supply system which is an improvement on the 201110104488.9 technology. The improvement is characterized in that a vaporization pipe is mounted in a vapor generating tank, and a saturated water pipe enters from the lower portion of the vapor generating tank and is connected with the vaporization pipe, so that pressure of saturated water entering the vapor generating tank can be effectively controlled to enable pressure to be higher than saturated pressure of the saturated water so as to avoid the saturated water from being vaporized in an upstream pipeline to generate vapor resistance. In addition, a heat conducting oil-water heat exchanger is arranged in a solar heat collector thermodynamic system, so that heat utilization rate is further improved.

Description

Solar energy/composite-energy closed cycle phase-change heating system
Technical field
The invention belongs to solar-heating engineering equipment technical field, relate to a kind of solar energy/compound closure circulating phase-change heating system.
Background technology
once in being 201110104488.9 patent application text, number of patent application disclosed a heating system with title before the applicant, this heating system contains solar thermal collector, boiler, steam generating tank, gas-distributing cylinder, with hot equipment etc., solar thermal collector successively with saturated water pipe, after being connected with circulation pipe, steam generating tank consists of a closed circuit, boiler successively with saturated water pipe, after connecting, steam generating tank and another set of circulation pipe consist of another closed circuit, a high-temperature pump is housed respectively on two closed circuits, the top of steam generating tank is connected with gas-distributing cylinder by steam pipe, be equipped with on gas-distributing cylinder many steam pipes respectively be connected hot equipment and indirect steam boiler to connect, in work, water mode with liquid-vapour-liquid in system circulates, the heat that solar thermal collector is produced passes to the hot equipment of using, when solar heat collector to supply heat is not enough, replenished by boiler.But this patented technology finds that through practical application the weak point still have is: add thermogenetic saturated water pipe through solar thermal collector and donkey boiler and be located at steam generating tank top, easy of like this UNICOM's steam generating tank upstream line vaporization, produce vapour locking, affect system's operation.
Summary of the invention
The present invention seeks to overcome the defective that 201110104488.9 technology exist, provide a kind of project organization more rational solar energy/composite-energy closed cycle phase-change heating system.
For achieving the above object, designer of the present invention has made improvement to 201110104488.9 technology, and it improves main points and is: generating tube is housed in steam generating tank, and saturated water pipe enters and is connected with generating tube from the steam generating tank bottom.
The further Technological improvement plan of the present invention also comprises: be equipped with the heat conduction oil to-water heat exchanger between the outlet pipe of solar thermal collector and return pipe, the outlet pipe of heat conduction oil to-water heat exchanger is connected with saturated water pipe, and the return pipe of heat conduction oil to-water heat exchanger is connected with two cover circulation pipes.
The further Technological improvement plan of the present invention also comprises: steam generating tank is vertical structure.
The further Technological improvement plan of the present invention also comprises: on the entrance before saturated water pipe enters steam generating tank, pressure-control valve is housed, reaches to improve and enter steam and send out the pressure of upstream line before tank greater than the effect of saturation pressure to avoid vaporizing of high-temperature water by regulating this control valve.
Compared with prior art, the invention has the beneficial effects as follows:
1, can effectively control the saturation water pressure that enters steam generating tank, make pressure higher than the saturation pressure of saturation water, avoid saturation water to produce vapour locking in the upstream line vaporization;
2, the solar thermal collector therrmodynamic system that adopts the heat conduction oil to-water heat exchanger to be combined with solar thermal collector can further improve heat utilization rate.
