Description
Technical field
This utility model relates to a kind of efficient capturing device of electrostatic for power plant's wet cooling tower emptying water smoke, belongs to the energy-conserving and emission-cutting technology field in thermal power plant.
Background technology
Thermal power plant wet cooling tower water loss includes evaporation loss, windage loss and blowdown loss three parts, and wherein evaporation loss and windage loss are with air together discharged in the air, cause the significant wastage of water resource, and this is that thermal power plant's water consumes one of maximum position.Statistical data shows, the water loss sum of wet cooling tower accounts for 65% the 75% of power plant's total loss water yield, and for 2 × 300MW fired power generating unit, its evaporation loss is about 1130t/h, accounts for the 62.08% of power plant's loss water yield；Wet cooling tower Ye Shi power plant water consumption while promoting unit efficiency sharply increases, and therefore, the water saving being directed to thermal power plant's wet cooling tower is imperative.
The gas vapour mixture that cooling tower emptying water smoke is made up of air and water.Until it exports more than cooling tower distribution channel, flowing is gas-liquid two-phase fluid water smoke and air, the particle diameter of its water form is typically in less than 100 microns, it is substantially free of effect by mechanical type dehydrater, but water droplet cohesion can be made to fall thus reclaiming moisture by electrostatic heavy gathering, namely high-pressure electrostatic recycle-water device.
But up to the present, the successful engineer applied case of cooling tower spray recovery technology based on high voltage electrostatic technique is also rarely reported, and existing water-saving technology still can not fundamentally improve the problem that wet cooling tower water loss is big.Based on this, this utility model is on forefathers' Research foundation, and applying high voltage electrostatic is heavy gathers principle, have developed a set of novel water smoke high-pressure electrostatic retracting device, it is adaptable to emptying water smoke is reclaimed in thermal power plant's wet cooling tower exit.This utility model device has the advantages such as simple in construction, corrosion-resistant, manufacture and operating cost is relatively low, long service life, provides a feasible way to the high efficiente callback for solving power plant cooling tower emptying water smoke, has wide future in engineering applications.
Summary of the invention
Task of the present utility model is in that to provide a kind of efficient capturing device of electrostatic for power plant's wet cooling tower emptying water smoke, for the emptying water smoke of efficiently trapping thermal power plant wet cooling tower.
A kind of efficient capturing device of electrostatic for power plant's wet cooling tower emptying water smoke,It is characterized in that: this device includes high-tension electricity electric supply installation, corona discharge electrode (negative electrode), positive six prism structures water smoke collector (anode), overhead device, grounding device.For convenience of the electric field that bloom is extremely uneven with structure, this utility model device adopts metal wire as corona discharge electrode and to arrange short and small tip (prickle) on corona wire.The corona wire of tube center connects high voltage direct current negative electrode, can form electric potential difference, i.e. one high-voltage electrostatic field of surrounding's formation of corona metal wire after energising in pipe.The remover of conductive glass steel tube of every corresponding positive six prismatic structures of corona prickle metal wire, as water smoke collector, restrains ground connection.For preventing corona wire and pole plate to be joined directly together by the moisture film on support, there is creeping discharge, corona wire is maked somebody a mere figurehead.
Beneficial outcomes of the present utility model is: its water smoke response rate is up to more than 80%；For the parameter of 2 × 300MW unit, according to the about 5 yuan/ton of calculating of existing power plant water price.According to putting into practice the data obtained, compared with not adopting this device, being averaged the response rate is 80%, and cooling tower evaporation capacity is 1130t/h, reclaim the water yield 904t/h.Yi Nian economizes the water yield about 7919000t, save water rate about 40,000,000 yuan.This installation cost about 40,000,000 yuan, removes operation maintenance expense, cost recovery in 1 year.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described as follows:
When using this utility model, first described a kind of efficient capturing device of electrostatic for power plant's wet cooling tower emptying water smoke is arranged on thermal power plant's wet cooling tower upper end, uses the electrostatic component fixing device (1) that dewaters to be fixed on cooling tower by the efficient capturing device of electrostatic of emptying water smoke.Corona discharge electrode (negative electrode) (2) connects high voltage direct current (7) negative electrode, is connected with earth lead (8) by all positive six prism structures water smoke collector (anode).High voltage direct current (7) is connected to controller (6), can control voltage swing.
During work, opening high voltage direct current (7), the voltage of regulable control device (6) control simultaneously is at suitable, a stable magnitude of voltage (discharge inception voltage).Corona discharge electrode (negative electrode) (2) bloom, and form electric field around.Form a large amount of free electron and anion due to corona discharge, make particle water charged.Under the effect of electric field; free electron collects level (anode) motion to positive six prism structure water smokes under the effect of electric field force; when by water in suspension granule in water smoke; free electron will be attached to formation anion on particle water; and it is gathered on anode under the effect of electric field force; release electronics; water in suspension granule is heavy to be gathered for liquid; simultaneously; due to charged rear interparticle interaction; originally little particle water is assembled and is integrated into bigger granule, flows down along positive plate under gravity, it is achieved the high efficiente callback of moisture.
