Description
Technical field
The present invention relates to a kind of equipment of the turbine discharge that condenses, a kind of specifically vacuum can the vortex vapour condenser.
Background technique
The vapour condenser of pure condensate formula Thermal Power Station has air cooling condenser, water cooling vapour condenser at present; Its principle is heat exchange; Be that the latent heat that water vapour liquefaction is emitted is taken away heat by air or water, its effect is: the first, set up and keep vacuum highly at the steam turbine relief opening; The second, the steam discharge of steam turbine is condensed into pure water supply boiler, accomplish the circulation of boiler circuit.
The advantage of air cooling condenser is a reduce water consumption, and shortcoming is that power consumption is big, investment is high, station service is high, the thermal efficiency is low; The advantage of water-cooled condenser is that station service is low, little investment, thermal efficiency height, and shortcoming is that water usage is big.These two kinds of vapour condenser all are based on heat exchange principle, different is just one of heat transferring medium be that air, one are water.Rely on the interior air-flow of vapour condenser of heat exchange principle design manufacturing all to be in flowing of a kind of flat flow; And flow velocity is higher; The airspeed of the water vapour of large-size steam turbine relief opening can reach 200m/s, but because atmospheric pressure very low (exhaust pressure of maximum high back pressure steam turbine is about 19.6kPa, and the exhaust pressure of minimum low back pressure turbine is about 4.9 kPa); Externally the ability of acting very a little less than, be referred to as " exhaust steam ".Though be exhaust steam, it still has 2300 kJ/kg at least than enthalpy, is higher than the ratio enthalpy of the liquid water under synthermal far away.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of energy-efficient, economic and practical vacuum can the vortex vapour condenser.
For solving the problems of the technologies described above, the technological scheme that the present invention adopted is:
Vacuum ability vortex vapour condenser; Comprise columniform vortex generation chamber; The bottom of vortex generation chamber is communicated with the water of condensation collecting chamber; The upper end of said vortex generation chamber connects vacuum pump through inhaling vacuum pipe, and the sidewall of vortex generation chamber offers the spout that sprays into turbine discharge with tangent being used to of inwall bus of vortex generation chamber, and the lower end of said water of condensation collecting chamber connects condensate pump through the water of condensation conduit pipe.
Further improvement of the present invention is: said spout is for connecting vortex generation chamber slit up and down, and the spout place is communicated with the nozzle of wedge shape.
Further improvement of the present invention is: the perforated pipe that a wall that is communicated with the suction vacuum pipe is provided with plurality of holes is run through at the center of said vortex generation chamber; The aperture of said perforated pipe top hole is less than the aperture of bottom hole, and the distribution density of top hole is less than the distribution density of bottom hole.
Further improvement of the present invention is: said vortex generation chamber is the structure that the outer wall of high hardness alloy steel making is enclosed with thermoinsulation material.
Further improvement of the present invention is: said vortex generation chamber and water of condensation collecting chamber are merged into the cylindrical of an equal diameters; The roof of the diapire of vortex generation chamber and water of condensation collecting chamber is merged into the central diaphragm of the annular that is positioned at cylindrical interior, is uniformly distributed with plurality of opening on the said central diaphragm.
Because the technological progress of having adopted technique scheme, the present invention to obtain is:
The present invention is the condensing equipment according to fluid swirling power theory and the theoretical development of fluid energy conservation.Turbine discharge tangentially gets into the vortex generation chamber from the nozzle of wedge shape from spout, because the exhaust steam pressure of steam turbine still has 4.9 kPa, and the pressure in the vortex generation chamber is near 0Pa, and steam discharge can get in the vortex generation chamber easily.Air-flow through nozzle quickens is done screw type acceleration circular movement in the vortex generation chamber; Make airspeed reach several times Mach number, the solid carbon dioxide steam becomes wet vapor gradually, and the water smoke that condenses is agglomerated into big water droplet gradually; Be thrown on the inwall of vortex generation chamber; And flow into downwards in the water of condensation collecting chamber along inwall, take away by condensate pump then, carry out the operation of continous-stable.The vortex generation chamber is a core component of the present invention; It is a cylindrical structural; Middle perforated pipe is offered hole; Make the aperture of the aperture of perforated pipe top hole less than the bottom hole, and make the distribution density of the distribution density of top hole less than the bottom hole, what then keep-up pressure on the inherent short transverse of vortex generation chamber is even.The vortex generation chamber is the high hardness alloy steel structure, and its outer wall is enclosed with thermoinsulation material, has improved the working efficiency of vortex generation chamber.The base plate periphery of vortex generation chamber has perforate, so that water of condensation flow in the water of condensation collecting chamber.
The present invention have working principle simple, economic and practical (reduce heating power power plant station service, improve the thermal efficiency), energy-efficient, safe and reliable, construction and installation simple, easy operating, maintenance are convenient, stable, than the water usage of clammy unit lack, the thermal efficiency height than Air-cooled Unit, the advantage that the clammy unit of output investment ratio is low.
