Abstract
The utility model relates to a direct air-cooling condenser for power plant equipped with air inlet diversion device, applicable to the thermal power plants which are short of water, including a heat-exchange pipe bundle, a wind-break wall(1), a wind airplane group(2), a steel structure platform(3) and vertical column(4). The steel structure platform (3) is connected upper to the vertical column (4). The heat-exchange pipe bundle and the wind airplane group are positioned outside the steel structure platform, which is characterized in that the periphery of the steel structure platform(3) under the wind-break wall(1) is vertically down equipped with the air inlet diversion device(5). The air inlet diversion device is used to change the direction of the air entering into the wind airplane intake in the periphery of the hollow condenser to make harm natural wind turn into useful natural wind, improve the performance of the hollow condenser, ensure the safe operation of the power plant and greatly reduce the investment cost and operating expense.
Description
Technical field:
The utility model relates to a kind of air cooling tubes condenser.Particularly relate to a kind of power station direct air-cooling condenser that installs air intake guide device additional.Be applicable to the heat power station of water scarcity.Belong to technical field of refrigeration equipment.
Background technology:
Power station direct air-cooling condenser structure in the past is made up of heat-exchanging tube bundle, blower fan group 2, steel structure platform 3, windbreak 1, column 4, jet chimney, condensing water conduit and electric control system etc. as shown in Figure 1.The air cooling tubes condenser of a large-scale power station has tens typhoon machines to combine heat exchanging tube bank to dry, the heat of steam in heat-exchanging tube bundle that generator is come blows away, make steam condense into water, move in design load with the steady pressure jar that keeps generating set.Because the said structure air cooling tubes condenser does not arrange that air intake guide device is used to change the direction that air enters the peripheral blower fan suction inlet of air cooling tubes condenser, makes the air intake direction of air cooling tubes condenser surrounding be parallel direction.Because a lot of blower fans is arranged together, the air quantity of required cooling usefulness is very big, the air intake of air cooling tubes condenser surrounding has formed certain wind speed, the wind-force of parallel direction has played ill-effect at the blower fan suction inlet of vertical direction, the blower fan exhaust capacity of periphery is descended, the heat exchange efficiency of the heat-exchanging tube bundle of this blower fan correspondence is descended.When the wind-force of natural wind increases, after the air draught effect and natural wind addition of blower fan, the wind speed of air cooling tubes condenser periphery is higher, can cause peripheral blower fan suction inlet to form negative pressure, the decrease in efficiency of blower fan, can cause the peripheral air cooling of air cooling tubes condenser unit air to pour in down a chimney phenomenon when serious, this air cooling unit is quit work, and cause hot air reflux, the heat exchange efficiency of whole air cooling tubes condenser is descended, condensing pressure is risen, reduce generated energy, can influence the safety of electric turbine when the natural wind wind speed is higher.In order to address the above problem, can only when design, adopt the quantity that increases heat exchange area and increase blower fan to solve, but can increase cost of investment and operating cost like this, increase difficulty to preventing freeze in winter again.Another kind method is that the power of the blower fan of air cooling tubes condenser blower fan group periphery is strengthened, and changes by the rotating speed that strengthens blower fan when strong wind and pours in down a chimney phenomenon.But it has increased cost of investment simultaneously, has increased operating cost during motion, and in when operation because rotation speed of fan improves, increased environmental noise greatly, influenced environment.As from the foregoing, the influence of natural strong wind is a difficult problem, and according to different wind directions, natural wind does not wait from 4%～20% the performance impact of air cooling tubes condenser, and the big more influence of wind speed is big more even reach 40%.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of heat exchange property that can improve air cooling tubes condenser is provided, and reduces the power station direct air-cooling condenser that has air intake guide device of cost of investment and operating cost simultaneously greatly.
The purpose of this utility model is achieved in that a kind of power station direct air-cooling condenser that installs air intake guide device additional, comprise heat-exchanging tube bundle, windbreak, the blower fan group, steel structure platform and column, steel structure platform upwards is connected on the column, heat-exchanging tube bundle and blower fan group are arranged on the steel structure platform, the blower fan group is arranged in the heat-exchanging tube bundle below, windbreak vertically upwards is arranged in the periphery of steel structure platform, it is characterized in that: the periphery of the steel structure platform of windbreak below vertically is furnished with air intake guide device downwards, be used to change the direction that air enters the peripheral blower fan suction inlet of air cooling tubes condenser, make harmful natural wind become useful natural wind, improve the performance of air cooling tubes condenser, guarantee the power plant safety operation, reduce cost of investment and operating cost simultaneously greatly.
The utility model installs the power station direct air-cooling condenser of air intake guide device additional, described air intake guide device is made up of the some connecting rods and the control lever of several blades and connection blade, some connecting rods vertically are arranged in the periphery of steel structure platform downwards, parallelly on each connecting rod be hinged with a plurality of blades, a plurality of blades connect with control lever, blade has the oblique upwards installation of certain angle, and angle be taken out control lever control after should calculating according to the meteorological condition of locality.During air process blade,, make the suction inlet of air guide blower fan through the guide functions of blade.When natural wind strengthened, the effect meeting of wind-force rushed at blower fan with air conducting, and promote blower fan and rotate, thus the power of minimizing blower fan.
The utility model installs the power station direct air-cooling condenser of air intake guide device additional, above-mentioned control lever is connected with manual or automatic governor motion, can be manual when the staff operates or the angle of automatic adjusting vane according to different wind speed, make the wind-guiding effect of blade be in best duty.
When the blower fan of air cooling tubes condenser all started, the air of most of blower fan flow through from the guiding device bottom, and the blower fan inhaled air around the blower fan group periphery imports blower fan through the blade of air intake guide device.Having changed original blower fan group periphery blower fan suction inlet all around like this is the phenomenon of negative pressure, originally the negative pressuren zone of the peripheral blower fan suction inlet of blower fan group has been shifted to the bottom of blade, negative pressuren zone moves down like this, do not influence the suction air quantity of the peripheral blower fan of blower fan group, guaranteed that air cooling tubes condenser blower fan group all evenly operates at full capacity.
