Description

For the steam generating tank in power station
Technical field
The present invention relates to field of solar thermal power generation, specifically refer to the steam generating tank for power station.
Background technology
Utilize solar electrical energy generation to have two large types, a class is solar power generation (also known as solar energy generating), and another kind of is solar thermal power generation (also known as solar energy thermal-power-generating).Solar energy generating is a kind of generation mode solar energy being directly transformed into electric energy.Four kinds of forms that it comprises photovoltaic generation, the induction of photochemistry Generate, Generation, Generator generates electricity and photo-biological generates electricity, have electrochemistry photovoltaic cell, photoelectrolytic cell and photocatalytic cell in photochemistry generating.Solar energy thermal-power-generating first converts solar energy into heat energy, then thermal energy is become electric energy, and it has two kinds of transform modes.One is that solar thermal energy is directly changed into electric energy, as the thermo-electric generation of semiconductor or metal material, and the thermoelectron in vacuum device and the generating of thermoelectricity ion, alkali metal thermo-electric is changed, and magnetohydrodynamic generator etc.Another kind of mode is that generate electricity similar with conventional thermodynamic, only its heat energy is not from fuel by solar thermal energy by the generating of heat engine (as steam turbine) drive electrical generators, but from solar energy.
At solar thermal energy after carrying out heat exchange with medium, generated electricity by heat engine drive electrical generators, but in thermal energy process, local medium steam is gathered into water droplet and piles up in conduit before entering heat engine, make being delivered in conduit of heat energy occur larger loss, and then reduce the generating efficiency of heat engine.
Summary of the invention
The object of the present invention is to provide the steam generating tank for power station, reduce the loss of solar thermal energy in medium generation modality conversion and transmittance process, improve the generating efficiency of heat engine.
Object of the present invention is achieved through the following technical solutions:
For the steam generating tank in power station, comprise tank body and the outer heat pipe of solar energy, the bottom of described tank body is communicated with by the bottom of the outer heat pipe of conduit and solar energy, the middle part of tank body is communicated with by the top of the outer heat pipe of conduit and solar energy, the sidewall of described tank body has feed tube, and on the top sidewall of tank body, have two symmetrical escape pipes, two described escape pipe inwalls rotate and is provided with nozzle, and multiple spiral salient is installed in nozzle inner walls, deflector is fixed with on the top of tank body, middle part outstanding formation back taper downwards of described deflector, and the male cone (strobilus masculinus) of this back taper is along bending in its center alignment, the axis of described escape pipe is just to this bending male cone (strobilus masculinus), also comprise heat pipe in multiple solar energy, in described solar energy, heat pipe is fixed in the outer heat pipe of solar energy by ring flange.When the present invention works, in feed tube, a certain amount of raw water is injected by water pump, raw water enters into heat pipe in solar energy by conduit, heat exchange medium is filled between heat pipe in heat pipe and solar energy outside solar energy, the heat utilizing solar energy collecting to produce starts to heat heat exchange medium, and raw water by heat pipe in solar energy in motion process in tank body, be heated to heat pipe direct boiling in the solar energy under the condition of high temperature, the water vapour formed is pulled in tank body, last by draining in escape pipe in heat engine to generate electricity, whole process Raw water only carries out between heat pipe and tank body to the transformation of water vapour outside solar energy, greatly optimize the space layout of equipment, simultaneously utilize solar energy to carry out harmless emission that heat exchange reaches product and intermediate product, meet the aim of energy-saving and environment friendly, and in tank body, along with the minimizing of water vapour heat energy, part steam can mutually merge and under the effect of himself gravity factor under slide to the bottom of tank body, again be delivered in the outer heat pipe of solar energy together with the raw water pumped into, and then realize recycling of raw water, reduce tank interior pressure to reduce the live load of outside water pump simultaneously,
Wherein drain into after in tank body at water vapour, the top of tank body is provided with the deflector that middle part convexes to form back taper downwards, and the male cone (strobilus masculinus) of this back taper is along bending in its center alignment, namely the longitudinal section of this back taper is inverted mentioned ridge-shaped, namely the motion that deflector is water vapour provides the route guiding of a curved surface, while accelerating water vapour discharge, prevent water vapour from piling up at tank body top and freely declining after causing part steam mutually to merge, and the both sides outer wall of tank body is symmetrical arranged two escape pipes, and rotation arranges nozzle on the inwall of escape pipe, and nozzle inner walls is fixed with multiple spiral salient, interact with spiral salient after steam enters nozzle, nozzle is driven freely to rotate, namely the kinetic energy of steam in escape pipe is increased, dispergated steam is pooled a steam spray post simultaneously, it is made to inject fast in heat engine, can further improve outer row's efficiency of water vapour, improve the generating efficiency of heat engine.
Further, also comprise control valve, described control valve is arranged on the conduit between tank body and the outer heat pipe of solar energy.In solar energy in heat pipe, the thermal discharge of heat exchange medium and the caloric receptivity of raw water need be consistent to realize the optimum efficiency that raw water is vaporized, but in practical operation, the throughput of raw water is often beyond the thermal discharge of the heat exchange medium in equivalent heat exchange, namely occur that part material water is not completely vaporised, be directly towed in tank body, add the idle work of raw water Forms Transformation, the present invention arranges control valve between tank body and the outer heat pipe of solar energy, before carrying out heat exchange, carry out intermittent adjustment to raw water to discharge, and then the equivalent heat exchange met in the outer heat pipe of solar energy and solar energy between heat pipe, to improve the efficiency that in tank body, water vapour injects.
Further, in multiple described solar energy heat pipe ringwise and array distribution on ring flange.In multiple solar energy, heat pipe distributes ringwise, namely makes heat pipe in solar energy fully contact with the heat exchange medium in the outer heat pipe of solar energy, ensures fully being heated of raw water, improve the growing amount of the steam in solar energy in heat pipe.
Further, the longitudinal section of described escape pipe is right-angled trapezium, and the internal diameter of escape pipe outwards successively decreases along its axis.Rotation through nozzle inside spin projection is accelerated, steam plume enters into escape pipe, be set to outwards successively decrease along its axis as the preferred internal diameter by escape pipe, the movement velocity of steam plume is accelerated further in escape pipe, avoid by the steam plume flowed out in nozzle formed vaporific rear directly with the collision of escape pipe occurrence of large-area, the wearing and tearing of reduction escape pipe.
The present invention compared with prior art, has following advantage and beneficial effect:
