Description
Technical field
The utility model belongs to air cooler field, relates to a kind of tubular type air cooling tubes condenser.
Background technology
World Water resource is day by day deficient, and air cooling technique becomes the main condensation technology of heat power station exhaust steam in steam turbine, comprises indirect air cooling and Direct Air-Cooled.Indirect air cooling good effect of heat exchange, is subject to seasonal effect little, but it exists that investment is large, system complex, need to expend the shortcomings such as certain water.Direct Air-Cooled Direct Air-Cooled is utilized surrounding air, is passed through the exhaust steam of surface-type heat exchanger condensing turbine, water-saving result is outstanding, but in the summer high temperature period, because environment temperature is high, direct air cooled condenser heat transfer temperature difference is little, required heat transfer area is large, and steam turbine Exhaust temperature rise can not meet generating set and completely send out requirement.
Under summer high temperature operating mode, for meeting steam turbine power generation unit, completely send out requirement, most of direct air cooled condenser, by increasing peak cooling device, is improved unit generation ability now.Peak cooling device is on original oblique top formula air cooler basis, increases water spraying atomization device, thereby reduces the ambient air temperature that participates in heat exchange.Because thermal power plant, water-deficient area climatic environment condition is comparatively complicated, in atmosphere, particles contained shape solid is more, and existing direct air cooled condenser heat exchanger tube is mostly the fin tube structure that is applicable to dry air cooling, wing is tall and big, spacing of fin is little, and between fin, air velocity is little, thus water smoke and solid particle on finned tube in conjunction with rear easy formation incrustation scale, the easy fouling of plate bundle is stopped up, and also can cause Direct Air-Cooled condenser to leak when serious.Because adopting air blast, direct air cooled condenser carries air, water spraying atomization Plant arrangement is in the blower fan top near heating surface bank, spray water from bottom to top, cause water spraying atomization weak effect, a large amount of shower waters are polymerized to water droplet, and water droplet is fallen by Action of Gravity Field, because Direct Air-Cooled below cannot arrange shower water, collect water tank, useless shower water consumption large percentage, device water-saving result reduces.
Utility model content
The utility model provides a kind of tubular type air cooling tubes condenser, solves the drawbacks such as the peak cooling device tube bank of existing power plant is easily stopped up, water-saving result is poor.
The technical solution of the utility model is as follows: a kind of tubular type air cooling tubes condenser, and a kind of tubular type air cooling tubes condenser, comprises blower fan, tube bank, shower water pipeline, and described blower fan, tube bank are installed up and down, and water tank is installed in this tube bank below; Described tube bank is arranged on the both sides of blower fan lower position, this tube bank arranged outside shower water pipeline, and this shower water pipeline is arranged in parallel with tube bank windward side; Shower water pipeline UNICOM water tank; Described tube bank is elliptical tube tube bank.
Described tube bank 4 is single elliptical tube structure.
Described single elliptical tube structure is formed or is restrained for a plurality of elliptical tubes by single elliptical tube tube bank
andjoint group becomes.
Described blower fan is induced air type blower fan.
Described shower water pipeline is with H shape branch structure.
The utility model is simple in structure, runner is large, fluid resistance is little, be difficult for stopping up, antifreeze, water-saving result good, steam-condensation can reach environment wet-bulb temperature, can solve summer steam turbine and exert oneself and be subject to a difficult problem for environment temperature restriction, meet Steam Turbine at full capacity, the requirement of stable operation.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is side view of the present utility model;
Fig. 3 is top view of the present utility model.
The specific embodiment
the utility model below in conjunction with accompanying drawing further illustrates.
as shown in Figure 1, 2, 3,an air cooling tubes condenser, comprising: blower fan framework 1, and blower fan 2, tube bank framework 3, restrains 4, shower water pipeline 5, water tank 6 and base 7.Restrain 4 upper ends and steam inlet 8 and Steam tube box 12, lower end are set lime set bobbin carriage 13 and lime set outlet 9 are set, admission port 17 and sewage draining exit 18 are set on water tank 6.Spray header 11, nozzle 10, feeding spraying pump 14 and pipe valve 15 are installed on shower water pipeline 5.Described blower fan 2 is arranged on blower fan framework 1 and is arranged in equipment upper end, down arranges successively tube bank 4, the water tank 6 of restraining framework 3 and being vertically mounted on its both sides.Restrain 4 outsides shower water pipeline is installed, and spray header 11 is arranged in parallel with tube bank 4 windward sides; Between each parts by securing member or be welded to connect.
Described tube bank 4 is elliptical tube tube bank, and the tube bank 4 that is arranged on a side is single elliptical tube structure.This single elliptical tube structure is formed or is restrained for a plurality of elliptical tubes by single elliptical tube tube bank
and(though be single row configuration, with respect to media flow in pipe, it is for being connected in parallel for connection.) form.This structural thermal area is large, fluid resistance is little, be difficult for obstruction, easy cleaning.
Described blower fan 2 is induced air type blower fan, is arranged in air cooling tubes condenser upper center, and for air cooling tubes condenser air side provides power, as far as possible little discharge shower water particle, for water smoke cohesion provides sufficient room; Adopt air inducing mode, heat transfer element air side is negative pressure, is conducive to evaporation of water heat-obtaining, and heat-transfer effect is good.Air cooling tubes condenser bottom water tank receives after the water droplet of not atomization and atomization the water droplet of cohesion again, has good water-saving result.
Described shower water pipeline, with H shape branch road, is conducive to shower water and is evenly distributed in tube bank windward side, and reduce shower water pipe resistance.
During equipment operating, steam flows into by restraining 4 upper steam imports 8, in the interior mixing of Steam tube box 12, after mixing steam through restrain 4 with cool exterior air heat exchange after be pooled to tube bank 4 lower end lime set bobbin carriages 13, then flowed out by lime set outlet 9.The air duct of top blower fan 2, as air outlet, is restrained 4 outsides as air inlet, blower fan 2 drive air streams through restrain 4 with steam heat-exchanging after, by blower fan 2 top air ducts, flowed out.
Shower water, by the moisture film gravitate of shower water pipeline 5 sprays in tube bank 4, from up to down flows.Have humidifying air, the effect that air themperature is reduced, has again water film evaporation heat transfer effect, has increased the heat transfer temperature difference of condenser, has improved again the heat transfer coefficient of air side.From up to down mobile water film flow is collected by lower end water tank 6 after crossing tube bank 4, and water tank 6 adds water and moisturizing by admission port 17, and in water tank, dirt is discharged by sewage draining exit 18.
The utility model, in less occupation area of equipment, has increased steam side circulation area, and pressure drop is little, and air side is less scaling, and equipment water-saving result is good.Solve the difficult problem that the peak cooling device tube bank of existing power plant is easily stopped up, steam turbine was exerted oneself and limited by environment temperature summer.
