Description
Technical Field
The utility model relates to a high-efficiency water cooling tower of a thermal power plant.
Background
In large-scale thermal power factory, the effect of cooling tower is in order to reduce the temperature of circulating water, can reduce the exhaust back pressure of steam turbine like this, improves power generation and system efficiency. The water cooling tower is internally provided with a dehydrator, a water distribution system and a filler from top to bottom, so that hot water from the condenser is delivered to the water distribution system through a pipeline, the water distribution system uniformly distributes the hot water to the filler, the hot water falls into a collecting tank below after passing through the filler, and the hot water is pumped into the condenser by a circulating water pump to continuously absorb the exhaust waste heat of the steam turbine. Air enters the tower from the space between the tower bottom struts, heat exchange is carried out between the lower part of the filler and water drops dropping from the filler, then the air enters the filler to further absorb the heat of hot water, when the air passes through the dehydrator, small water drops in the air are blocked and collected, then wet air flows upwards from the tower, and finally enters high altitude from the tower top.
In the whole process of absorbing heat in the water cooling tower, the resistance generated by the impact of the falling motion of water drops dropping from the filler on the air is about 40 percent of the resistance in the whole tower, so the air flow in the tower is greatly reduced; on the other hand, due to the influence of the falling motion of water drops, the air flow of the central area of the filler is small, the flow speed is low, and the heat exchange effect is poor.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model aims to provide the high-efficiency water cooling tower.
The technical scheme adopted by the utility model is as follows:
a high-efficiency water cooling tower comprises a tower body, a support column, a dehydrator, a hot water pipeline, a water distribution system, a filler, a high-level water collecting system, a filter screen, an enclosing wall and a water collecting tank. A dehydrator, a hot water pipeline, a water distribution system, a filler and a high-level water collecting system are arranged in the tower body of the water cooling tower from top to bottom; a water distribution system is arranged outside the lower part of the tower body, a wall is arranged outside the water distribution system, and a filter screen is also arranged above the water distribution system; the water distribution system outside the tower is communicated with the high-level water collection system in the tower.
The utility model has simple structure and less investment, can improve the air flow of the water cooling tower and the heat exchange efficiency thereof, thereby playing the roles of reducing the temperature of circulating water and improving the power generation power and the power generation efficiency.
Drawings
Fig. 1 and 2 are schematic views of the present invention, wherein fig. 1 is a cross-sectional view and fig. 2 is a top view.
Detailed Description
The present invention is described in further detail below with reference to the attached drawings.
The reference numbers of figures 1 and 2 are as follows:
1-tower body 2-water removing device 3, 5-water distributing system 4-filter screen 6, 12-filler 7-support column 8-hot water pipeline 9-high water collecting system 10-water collecting tank 11-enclosing wall 13-wind-shield wall
In the embodiment shown in fig. 1 and 2, a water eliminator 2, a water distribution system 3, a filler 12 and a high-level water collection system 9 are respectively installed in a tower body 1 from top to bottom, a hot water pipeline 8 is installed in the center of the tower body, a filter screen 4, a water distribution system 5 and a filler 6 are installed outside the tower body 1, a wall 11 is built outside the water distribution system 5, the high-level water collection system 9 is communicated with the water distribution system 5, a wind blocking wall 13 is installed between the filter screen 4 and the water distribution system 5, and a water collecting tank 10 is built below the water distribution system 5.
In the normal power generation process of a thermal power plant, hot water from a condenser enters a water distribution system 3 in a tower body 1 through a hot water pipeline 8, the hot water uniformly flows into a filler 12 after passing through the water distribution system 3, the hot water flows out from the bottom of the filler 12 and is collected by a high-level water collection system 9, then the hot water enters a water distribution system 5, is uniformly distributed by the water distribution system 5 and then drops into a water collection tank 10 below, and the hot water is pumped into the condenser again by a circulating water pump to absorb the exhaust waste heat of a steam turbine. The filter screen 4 on the water distribution system 5 can prevent the impurities such as flying floc, plastics and the like in the ambient atmosphere from entering the water distribution system 5 after being blown by wind.
The air outside the tower body 1 is impacted by water drops dropping from the water distribution system 5 after passing through the filter screen 4, then enters the tower body 1 through the space between the pillars 7, and continuously rises in the tower body 1 and is discharged into the high-altitude atmosphere after sequentially passing through the high-position water collection system 9, the filler 12, the water distribution system 3 and the dehydrator 2. Because the air can be impacted by the dripping water drops after passing through the water distribution system 5, the sinking air has a certain speed, and because the influence of the water drenching at the lower part in the tower is eliminated, the air flow entering the tower body 1 can be greatly increased, and the cooling effect in the whole tower is improved. Meanwhile, because the lower part of the high-level water collecting system 9 does not drip water, air entering the tower body 1 can uniformly enter the filler 12, and therefore the heat exchange efficiency in the whole filler 12 is improved. In order to further enhance the heat exchange effect, a filler 6 can be arranged below the water distribution system 5. In addition, the enclosing wall 11 around the water distribution system 5 can prevent the air flow in the tower body 1 from being adversely affected by the environmental wind, force the sinking air passing through the water distribution system 5 to enter the tower body 1, and reduce the noise pollution of the surrounding environment caused by the water spraying.
In the area with rich wind resources, the wind-blocking walls 13 are symmetrically arranged between the filter screen 4 and the water distribution system 5, the height of the wind-blocking walls 13 exceeds that of the filter screen 4, and meanwhile, the inner sides of the wind-blocking walls 13 are connected with the tower body 1, so that when environmental wind blows from the side surface of the tower body 1, the environmental wind is influenced by the wind-blocking walls 13 and the tower body 1, part of the environmental wind passes through the filter screen 4 and the water distribution system 5 along the wind-blocking walls 13 to enter the bottom of the tower body 1, then turns back upwards, absorbs heat and then is discharged into the atmosphere from the top of the tower body 1, thereby further increasing the air flow in the tower body 1 and enhancing the heat exchange effect.
The present invention is not limited to the above-described preferred embodiments, and various other forms of products can be obtained by anyone in light of the present invention. However, any changes in shape or structure, which are the same or similar to the technical solutions of the present invention, are within the protection scope.
