Abstract
The invention provides an efficient and energy-saving recovery device of a cooling tower. The device comprises an insulation support base fixed to a round opening in the top of the cooling tower, the inner wall of the insulation support base is longitudinally and fixedly connected with anode lines, and an S-shaped cathode plate is arranged between every two anode lines in an inserted mode. The cathode plates are fixed to beams which are fixed to the insulation support base, and an arched beam is connected to the part above the beams. The anode lines are located at the S-shaped wave trough positions of the cathode plates. Anode line burrs are wound around the anode lines at intervals. The burr line type is adopted for an anode, the S-shaped cathode plates are additionally arranged, so that the ascending direction of airflow is changed, and efficiency of removing vapor is improved; the grain diameter of the vapor in flowing is increased to several millimeters from water drops of several microns, air flowing will not make the vapor be suspended any more, the water drops of which the grain diameter is larger than a settlement critical point settle in a water storage pool, the water drops of which the grain diameter is smaller than the critical point continuously increase, and air without any liquid drops ix exhausted and is colorless and transparent; under the condition that circulation water heat exchanging is not affected, the volatized vapor is recovered so that the purposes of saving the water and electricity and not increasing halide ions can be achieved.
Description
technical field:
The present invention relates to power plant's environmental protection and energy saving field, specifically the energy-efficient retracting device of a kind of cooling tower.
background technology:
At present the recirculated water after power plant and steam heat exchange is to spray and cross-ventilation through cooling tower, completes heat exchange and produces aqueous water, volatilizes vaporous water, with heating and cooling on vaporous water, separate out supersaturation drop, formation two-phase flow steam.Recirculated water rises, becomes the two-phase flow steam of Air Flow entrained drip at decline procedure division mist droplet water air, according to cooling tower design formula, and volatilization water inventory
The a=0.0014* recirculated water total amount * temperature difference;
With 300MW unit quantity of circulating water=3 ~ 4 ten thousand stere/times;
The temperature that recirculated water declines at cooling tower is 10 DEG C of left and right;
0.0014*3500*10=490 ton/time the water that volatilizees;
So 300MW unit needs 490 tons of moisturizings/time;
The required power consumption 3000KW of moisturizing, and with the increase of volatilization water, residual halogen ion increases, and causes the life of equipment of circulating pump and corrosive pipeline, system to shorten, maintenance amount and cost strengthen.
summary of the invention:
In order to address the above problem, provide the energy-efficient retracting device of a kind of cooling tower to address the above problem.
Technical scheme of the present invention is: the energy-efficient retracting device of cooling tower, comprise the insulated leg that is fixed on cooling tower top circular open, insulated leg is that a circle hat-shaped insulator is buckled in cooling tower top, inwall is longitudinally fixedly connected with some anode lines in a row, the interspersed minus plate that is furnished with S shape between every two anode lines, minus plate and crossbeam are fixed, some crossbeams and anode line parallel longitudinal direction are arranged, crossbeam is fixed and insulated leg, crossbeam top is connected with arched girder, anode line is positioned at the S shape wave trough position of minus plate, anode line, and upper interval is wound with anode line burr.
The present invention has following beneficial effect: minus plate is the polar plate type that S type forms efficient pass-through type, anode adopts prickle wire pattern, S template has increased pole plate process, change air-flow ascent direction, improve the efficiency except fog, mobile gas is from the water droplet of several micron grain sizes, increase to several millimeters, Air Flow can not make it to suspend again, be greater than the water droplet of the critical particle diameter of sedimentation, be deposited in cistern below, being less than the critical continuation of sedimentation increases, discharge without any the air of drop, water white transparency, in the situation that not affecting circulating water heating exchange, volatilized fog is reclaimed, to reach water saving, the object that economize on electricity and halogen ion do not increase.
