Abstract
The present invention discloses a method for eliminating the heat exchanging corner and an air condenser thereof. According to the method, the air outlet of an axial flow fan is provided with one group of guiding plate for changing the air direction partially and flowing to the heat exchanging corner. The air condenser manufactured according to the method of the invention comprises a steam distributing pipe (1) which is connected with a condensation water tank (3) through two groups of heat exchanging pipes (2). The axial flow fan (4) which is equipped with a fan cover plate (5) is provided below the heat exchanging pipe. One group of guiding plates (6) is provided on the fan cover plate, wherein the guiding direction of the guiding plate is oriented to the heat exchanging corner (8) at the bottom of the heat exchanging pipe. According to the invention, the air flow and the heat exchanging efficiency at the bottom corner of the heat exchanging pipe can be increased with lower cost and simple method at the state that the noise is not increased.
Description
Technical field
The present invention relates to a kind of aerial condenser, particularly a kind of method and aerial condenser of eliminating heat exchanging corner.
Background technology
The large-scale direct aerial condenser group in thermal power plant includes a plurality of direct aerial condensers unit at present, and the structure of each direct aerial condenser unit is basic identical.The steam of discharging from steam turbine is assigned to a plurality of steam-distributing pipes through pipeline, and each steam-distributing pipe bottom is connected the similar A type of structure respectively through the heat exchanger tube that two groups of symmetries are obliquely installed with condensate tank.Below heat exchanger tube, be provided with one or one with axial flow blower constitute the axial flow blower crowd; The wind of axial flow blower directly blows on heat exchanger tube and the steam-distributing pipe heat is taken away; Steam in exchange heat pipe and the steam-distributing pipe cools off, and cooled condensed water is discharged through condensate tank.
This direct aerial condenser unit is because the wind of axial flow blower is direct blowing from the bottom to top, and most wind-force directly blow to the top of steam-distributing pipe and heat exchanger tube, so the top heat exchange effect of steam-distributing pipe and heat exchanger tube is best.Because heat exchanger tube is obliquely installed, after wind-force runs into heat exchanger tube, flow on most wind direction, have only very little wind-force to flow downward, cause the heat exchanger tube bottom, four of the heat exchanger tube bottom angles particularly, exchange capability of heat is poor especially, has almost become heat exchanging corner.Make the heat exchanger tube heat radiation at place, dead angle not smooth, heat exchange efficiency descends, and the heat exchange efficiency on whole air cooling island is descended, and condensing pressure rises, and reduces generated energy.Summer particularly is because the bad meeting of heat exchange makes air cooling condenser undercapacity; During winter, also can cause the heat exchanger tube freeze damage, cause interruption of service.
At present, the method one of solution is quantity and the length that increases heat exchanger tube, improves heat exchange area, can increase cost of investment like this.Another kind method is quantity and the power that increases axial flow blower, improves air quantity and blast and strengthens exchange capability of heat.These two kinds of methods; Though overall exchange capability of heat increases, but still the exchange capability of heat and the efficient at place, heat exchanger tube dead angle be can not effectively improve, cost of investment and operating cost also increased simultaneously; Second method is because blower fan quantity and power increase; Rotating speed improves, and noise is bigger during operation, influences environment.
Summary of the invention
The objective of the invention is to; A kind of method and aerial condenser of eliminating heat exchanging corner is provided, can be under the situation that does not improve noise, with less cost and simple method; Improve the air mass flow at dead angle, heat exchanger tube bottom, improve the heat exchange efficiency at dead angle, heat exchanger tube bottom.
Technical scheme of the present invention: a kind of method of eliminating heat exchanging corner is that the air outlet at axial flow blower is provided with one group of guide plate, and the part wind direction is changed, and blows to heat exchanging corner.
In the method for above-mentioned elimination heat exchanging corner, the guide angle α of said guide plate is 80～100 °.
A kind of aerial condenser of eliminating heat exchanging corner comprises steam-distributing pipe, and the steam-distributing pipe bottom is connected with condensate tank respectively through two groups of heat exchanger tubes, below heat exchanger tube, is provided with axial flow blower, and axial flow blower is provided with the blower fan cover plate; The blower fan cover plate is provided with one group of guide plate, and the guide direction of guide plate is pointed to the heat exchanging corner of heat exchanger tube bottom.
In the aerial condenser of above-mentioned elimination heat exchanging corner, guide plate is connected with the blower fan cover plate through gripper shoe.
In the aerial condenser of aforesaid elimination heat exchanging corner, the guiding angle [alpha] of said guide plate is 80～100 °.
Compared with prior art, the present invention only is provided with one group of guide plate through the air outlet at axial flow blower, and the part wind direction is changed, and blows to heat exchanging corner.Just can not increase heat exchange area, not increase the air mass flow that improves the original heat exchanging corner of aerial condenser under the situation of blower fan quantity and power of fan, improve heat exchange efficiency, reduce cost of investment.And reduced operating cost.Owing to need not improve the rotating speed and the power of blower fan, so can not increase the pollution that noise has environment.

Being labeled as in the accompanying drawing: 1-steam-distributing pipe, 2-heat exchanger tube, 3-condensate tank, 4-axial flow blower, 5-blower fan cover plate, 6-guide plate, 7-gripper shoe, 8-heat exchanging corner.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment a kind of method and aerial condenser of eliminating heat exchanging corner of the present invention done further to specify, but not as the foundation of the present invention being done any restriction.
Embodiment.Existing aerial condenser principle is as shown in Figure 2, and the direction of arrow among Fig. 2 is represented the flow direction of wind.Can find out from Fig. 2, have heat exchanging corner 8 in the bottom of heat exchanger tube 2.The method of elimination heat exchanging corner of the present invention, as shown in Figure 1, the direction of arrow among Fig. 1 is represented the flow direction of wind.Visible owing to the air outlet at axial flow blower 4 is provided with one group of guide plate 5 by Fig. 1, wind wind direction after running into guide plate 5 changes, and the guide angle of guide plate is that the wind of 80～100 ° of axial flow blowers 4 can directly blow to heat exchanging corner 8.
The aerial condenser of elimination heat exchanging corner of the present invention is as shown in Figure 3; It comprises steam-distributing pipe 1 of the prior art; The two groups of heat exchanger tubes 2 in steam-distributing pipe 1 bottom are connected with condensate tank 3 respectively, below heat exchanger tube 2, are provided with axial flow blower 4, and axial flow blower 4 is provided with blower fan cover plate 5; Improvement of the present invention is that four guide plates 6 are set on blower fan cover plate 5, and guide plate 6 is connected with blower fan cover plate 5 through gripper shoe 7.The guiding angle of guide plate 6 is about 90 °, and the guide direction of guide plate 6 is pointed to four the poorest heat exchanging corner 8 of exchange capability of heat of heat exchanger tube 2 bottoms.So just can under the situation of the heat exchange area that does not increase heat exchanger tube 2 and axial flow blower quantity or power, improve the situation that can occur heat exchanging corner 8 in the prior art.Owing to do not change existing blower fan partly,, do not increase the pollution of NOISE ON ENVIRONMENT so noise still is controlled at existing level.Can improve simultaneously the air mass flow of the original heat exchanging corner of heat exchanger tube 2.Reduce cost of investment, and reduced operating cost.
