Description
Technical Field
The utility model relates to a large and medium-sized industry cooling tower field especially relates to the frostproofing and geomantic omen cooperation of existing large and medium-sized natural draft cooling tower and reforms transform the technique.
Background
The large and medium industrial cooling tower is a heat exchange device widely applied in the industrial field. Is a very important cooling device, and the quality of the performance of the cooling device has great influence on the energy consumption and the water consumption of the production.
According to statistics: in a conventional thermal power plant, only about 40% of the energy of fuel combustion is converted into electric energy, and 48% is discharged with cooling water. In a nuclear power plant, only about 33% of the nuclear energy is converted into electrical energy, and the other 67% is converted into waste heat which is carried away by cooling water. And most of the heat in the cooling water is discharged to the atmosphere through the cooling tower. There are data showing that: the efficiency of the cooling tower is only about 50%, which is at a low level.
The natural draft cooling tower mainly comprises: the device comprises a hyperbolic cooling tower cylinder, a cooling tower reservoir, a central shaft, a cross-shaped inner-area main water tank, a water conveying tank, a cross-shaped outer-area main water tank, a water distribution pipe, a spraying device, a packing layer and the like.
In the operation process of the natural ventilation cooling tower, circulating cooling water (hot water) passes through the central vertical shaft and the water distribution pipe groove, is sprayed out through the nozzles, and is sprayed and falls on the surface of the water spraying filler in a water mist mode. In the packing area, cooling water flows through the surface of the packing in the form of a film and performs heat and mass transfer with air. Below the filler area, the cooling water is gathered into liquid drops to fall in a raindrop mode, and the liquid drops contact with cold air to exchange heat in the falling process and finally fall into a water collecting tank.
The central shaft of the cooling tower is a vertical shaft, the bottom of the vertical shaft is connected with a circulating water pressure pipe, the top of the vertical shaft is open, and hot water is delivered to a water distribution elevation through the vertical shaft. Through interior district main basin and outer district main basin, send water to the distribution pipe, the shower nozzle of rethread installation in these distribution pipe both sides will be sprinkled water on the filler.
Whether the water is distributed in a groove mode or in a pipe mode, the total flow direction of hot water after the hot water enters the cooling tower is from inside to outside. The water distribution direction from inside to outside is adopted because the vertical shaft is arranged in the center inside the cooling tower, the influence on the ventilation resistance of the air inlet of the cooling tower is small, and the aim of water distribution can be conveniently achieved through the water distribution tank or the water distribution pipe. In this distribution system arrangement, the hot water flows from the central shaft in the cooling tower to the surrounding distribution areas, so that the total flow is from the inside to the outside.
The central shaft cooling tower has wide application all over the world, in the cooling tower with large water spraying area, the main water tank is very long, the elevation change along the water surface of the water tank is large when the flow is constant, and especially when the flow is small under the partial load of the cooling tower, the far end or the tail end of the water tank can have little water or no water.
Practical measurements and numerical simulations show that: the air flow rate of the natural draft cooling tower is gradually reduced from outside to inside along the radius direction of the cooling tower. Namely: the outer zone air flow velocity is greater and the inner zone air flow velocity is lower.
The results were: the cooling water gradually decreases from inside to outside along the radius direction. And the air quantity entering the tower is gradually increased from inside to outside along the radius direction of the cooling tower. I.e., where the amount of water is large, the amount of air is small. Where the amount of water is small, the amount of air is large.
The presence or absence and the size of the water flow represent the distribution of resistance of the air in the tower, the air flow rarely passes through the area with high water spraying density, and the air is short-circuited in the water-free area. The place with water is lack of air, and the place with air is free of water. The water vapor can not fully exchange heat, the heat exchange efficiency is low, and the cooling capacity of the tower is reduced.
The mismatching of air and water can directly influence the air distribution and the ability of the filler to play a cooling role, and the performance of the cooling tower is greatly reduced.
At present, two areas of water distribution, namely inner area water distribution and outer area water distribution, are mostly adopted in large natural ventilation cooling towers. Take a natural draft cooling tower with a diameter of 120 meters as an example. A circle formed from the center of a vertical shaft of the cooling tower to a position with a radius of 30 meters is an inner area. The radius is 30 meters to 60 meters, and the formed ring is the outer zone.
Inner zone area is 2826m 2 Outer zone area 8478m 2 . The outer zone area is 3 times the inner zone area. It can be seen that 75% of the heat exchange of the cooling tower is carried out in the outer zone. The outer region has good air-water matching, which is the key for improving the efficiency of the cooling tower.
The flow direction of the cooling water is as follows: and inner-area water distribution is finished when the central vertical shaft flows to the position with the radius of 30 meters of the cooling tower through the inner-area main water tank, and the inner-area water distribution is carried out. And water distribution in the outer area is carried out, wherein water is conveyed to the radius of 30 meters of the cooling tower from the central shaft through the water conveying tank with the length of 30 meters, and flows to the radius of 60 meters from the radius of 30 meters through the main water tank in the outer area, so that water distribution in the outer area is carried out.
The water flow direction of the inner zone main water tank or the outer zone main water tank is inward and outward.
When hot water flows from inside to outside, the total water amount of the hot water is gradually reduced when the hot water passes through one water distribution pipe, when partial flow of the cooling tower runs, the water is not available at the far end or the tail end in the same main water tank, and short circuit is formed in the region where the cooling tower is not available or is low in water content by airflow, so that the cooling performance of the cooling tower is greatly reduced.
The structure of the cooling tower determines: the air quantity of the tower is gradually reduced from outside to inside. Primarily due to the fact that air is introduced into the inner region of the cooling tower, it is necessary to pass through the rain zone of the outer region of the cooling tower. The deeper the rain passes towards the center of the cooling tower, the greater the resistance and the smaller the air volume.
At present, a large amount of water is distributed in different areas at home and abroad, and the water distribution direction is from inside to outside. Under 100% of design working conditions, the tail ends of the inner zone main water tank and the outer zone main water tank can be ensured to have water to run. But at 75%, 50%, or even less of the amount of circulating cooling water, water operation is not necessarily guaranteed at the ends of the inner zone main water tank and the outer zone main water tank.
The cooling tower is designed according to 100% working condition, namely the flow rate of the circulating cooling water is designed according to 100%. Due to the rapid rise of new energy power generation, most of the units operate under partial load for most of the time. The energy-saving reconstruction of a double-speed pump or the frequency conversion reconstruction of a circulating water pump is mostly carried out on the circulating water pump in the power plant for the purpose of saving electricity. So that the circulating water quantity can be matched with the load of the unit at any time. Therefore, the economic operation of the circulating water is realized under the conditions of meeting the vacuum and safety of the unit.
The consequence is: 1. in winter, the cooling tower is frozen because insufficient cooling water (hot water) is available at the periphery of the cooling tower. Extra measures must be taken to prevent freezing. Due to the large construction of the cooling tower itself, the cost is expensive regardless of the measures taken. 2. Under partial load, the remote or terminal end of the main flume is low or free of water causing the presence of a water free zone, which short circuits the air. The short-circuited air reduces the tower exit air temperature of the cooling tower, so that the draft of the cooling tower is reduced. Eventually reducing the amount of air entering the tower. The cooling tower performance deteriorates.
The draft of the cooling tower comes from the density difference between the air entering the tower and the air leaving the tower. The better the heat exchange performance of the cooling tower, the higher the temperature of the air out of the tower, the larger the air density difference of the air in and out of the tower, the larger the draft of the cooling tower and the larger the air inlet amount of the cooling tower. The more the air quantity entering the tower is, the more the heat of the cooling water is taken away, and the lower the temperature of the water leaving the tower is. The better the cooling tower performance.
The utility model discloses aim at solving the basis heat exchange efficiency that prevents frostbite in winter and improve the cooling tower of existing big-and-middle-sized natural draft cooling tower economically high-efficiently.
The improvement of the basic heat exchange efficiency of the cooling tower has been proposed in the high Jinbai patent ZL 202021614717.2. The new cooling tower is very suitable to adopt ZL 202021614717.2. However, the transformation of patent ZL202021614717.2 to the existing large and medium-sized cooling tower has the following greatest defects: large engineering quantity, high construction cost and long construction period. The popularization and the application of the patent are limited.

Detailed Description

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-2, the utility model provides a cooling tower with partially reverse water distribution, which comprises a cooling tower body 1, wherein a filling region 6 is arranged at the bottom end of the cooling tower body 1, and a reservoir 2 is arranged at the bottom of the filling region 6;
The bottom of the reservoir 2 is connected with a water pump 13 through a pipeline 15, the water pump 13 is connected with a condenser 14 through a pipeline 15, and the condenser 14 is connected with the central shaft 3 through a pipeline 15.
The utility model discloses mainly solve the technical and economic problem that big-and-middle-sized cooling tower reformed transform. Namely, the maximum improvement result is obtained with the minimum economic cost.
The structure of the natural draft cooling tower determines: the air quantity is gradually reduced from the outside to the inside along the radius direction of the cooling tower. The existing water distribution mode at present is as follows: along the radius direction, the cooling water flows from inside to outside, and the amount of the cooling water in the main water tank is smaller and smaller. Even if water is distributed in the inner and outer areas, the total flow direction of the cooling water flows from inside to outside. Under the condition of partial load of circulating cooling water, the far ends or tail ends of the inner main water tank and the outer main water tank have little water or no water. The larger the size of the cooling tower, the more severe the situation.
Theoretically, the air field and the water spray density inside the cooling tower should be uniform everywhere, but the method does not exist in a large natural draft cooling tower. Due to the characteristics of the structure of the natural draft cooling tower: the air quantity of the cooling tower is smaller along the radial direction of the cooling tower. The total direction of the cooling water is from inside to outside along the radius direction, and the amount of the cooling water is gradually reduced. Namely: the place with large air quantity has small water quantity. The place with small air quantity has large water quantity. This should be the root cause of the inefficiency of the cooling tower.
The solution for the new construction of cooling towers has been proposed in patent ZL20202 1614717.2. The technical scheme and the solution mainly aim at the reformation of the existing large and medium natural draft cooling tower.
As shown in fig. 3, current medium and large natural draft cooling towers are typically split into two stages of water distribution, i.e., inner zone water distribution and outer zone water distribution. The main water tank is constructed in two sections. Divided into an inner zone main water tank 101 and an outer zone main water tank 102. The inner zone main water trough 101 communicates with the central shaft 3 at its open end and terminates at radius 1/2 of the cooling tower. The outer zone main water trough 102 starts at the cooling tower radius 1/2 at the open end and ends at the cooling tower outer edge. The outer zone main water tank 102 is coupled to the central shaft 3 and the open end of the outer zone main water tank 102 through a water delivery tank. The length of the water conveying tank is 1/2 of the radius of the tower, and one end of the water conveying tank is opened and communicated with the central vertical shaft 3. The other end opening of the water conveying tank is communicated with the opening end of the outer zone main water tank 102.
In this inside-out distribution mode, under partial load, the far end or tail end of the main flume will have little or no water. And the heat exchange area of the outer zone is 3 times that of the inner zone. The heat exchange area of the outer zone accounts for 75% of the total heat exchange area, and the tail end of the outer zone main water tank 102 has little water or no water, so that the heat exchange performance of the cooling tower is greatly influenced.
The water distribution in the inner area and the outer area is realized by 4 flashboards in the central shaft 3, and when the water distribution device runs in winter, the flashboards are put down to block the water inlet of the main water tank 101 of the inner area, so that the water distribution in the inner area is closed, and the water distribution running of the outer area is realized. However, since the water amount in the inner zone is closed to be only 25% of the total water amount, when the single-circulation water pump 13 is operated in winter, the far end or the tail end of the outer zone water distribution main water tank still has little water or no water. And because the flashboard is not operated frequently, the environment is moist, the phenomenon of locking exists mostly, can not operate, the regional water distribution effect is not obvious, also can not play the frostproofing effect of cooling tower in winter.
In winter, the temperature is low, the cooling water quantity is small, and most of the tail ends of the main water tanks have little water or no water. No hot water or little hot water is arranged on the outer edge of the cooling tower, so that a large amount of ice is directly formed on the cooling tower, and the cooling tower is damaged.
The cooling tower freezes, especially outstanding north area. The rolling curtain method is mainly adopted, and partial air inlets of the cooling tower are shielded by the rolling curtain for the cooling tower in winter, so that the air inlet amount of the cooling tower is reduced. So that the temperature of the outlet water of the cooling tower is raised, and the cooling tower is not frozen. However, the method has high cost, and the vacuum of the steam turbine unit is poor due to the fact that the temperature of the water discharged from the cooling tower is increased, and the economical efficiency of the steam turbine unit is seriously affected.
The cost factor of the modification of the cooling tower is considered. The complete water distribution reconstruction of the whole tower takes a cooling tower with the diameter of 120 meters as an example, a 4X60 meter water conveying tank needs to be newly built, and a 4X60 meter main water tank needs to be newly built. And because of the full flow water distribution, the end area of the water delivery tank and the main water tank is 25 percent larger than that of the 75 percent flow outer zone main water tank 102 of the original tower.
Now, the 25% water distribution in the inner region is not reconstituted. Thus most of the original structure can be reserved for reuse. Only a 4X 30-meter water conveying tank needs to be newly built, and 75% of water in a heat exchange area of the cooling tower can be reconstructed. And part of the reverse water distribution reconstruction is carried out, and the manufacturing cost is only or less than 25 percent of the total tower reverse water distribution reconstruction cost.
For partial reverse water distribution reconstruction, the performance improvement of reverse water distribution of the inner area has no great influence of reverse water distribution of the outer area. Therefore, the efficiency without reverse water distribution sacrifice for the inner zone should be equal to or less than 25% based on 100 units of full tower water distribution lift efficiency.
Therefore, the economic investment of 25 percent is used, and the economic efficiency of more than 75 percent of the original 100 percent investment is obtained. The problem of freezing of the cooling tower in winter is also solved.
As shown in fig. 2, the present invention provides a specific solution: and reconstructing a water distribution structure of the inner area and the outer area of the existing cooling tower. The method comprises the following specific steps: a new water transport tank 202 having the same length, width and height as the old water transport tank 201 is constructed. One end of the new water delivery tank 202 is plugged. Further: the open end of the existing outer zone main water tank is disconnected with the old water delivery tank 201, and the disconnected part of the outer zone main water tank is blocked. Further: the new water conveying tank 202 is arranged between the radius 1/2 of the cooling tower and the outer edge of the cooling tower, and the open ends of the new water conveying tank and the old water conveying tank are communicated. Further: the upper wall surface at the outer edge of the cooling tower of the new water conveying tank 202 and the lower wall surface at the outer edge of the outer-zone main water tank 102 are respectively communicated, the communicated area is equal to the sectional area of the water conveying tank, and a U-shaped channel for circulating cooling water is formed.
The result of such a reconstruction is:
the inner zone cooling water is distributed by the shaft through the inner zone main water tank 101, and the flow direction of the cooling water is from inside to outside. The water distribution area is 25 percent.
The cooling water in the outer area flows to the radius 1/2 of the cooling tower of the main water tank 102 in the outer area through the main water tank 102 in the outer area from the vertical shaft through the old water conveying tank 201, the new water conveying tank 202 and the U-shaped turn to the outer edge of the cooling tower of the main water tank 102 in the outer area, and water distribution is carried out. The flow direction of the cooling water is from outside to inside. The water distribution area was 75%.
In the outer water distribution area, the large water volume of the place with large air volume is realized. And the water quantity is small in places with small air quantity. And the outer edge of the cooling tower is always in a hot water state in winter, so that the freezing of the cooling tower is avoided.
No matter the circulating water pump 13 operates in double speed or the circulating water pump 13 operates in variable frequency, the outer edge of the cooling tower can always ensure hot water, and the cooling tower is prevented from being frozen.
And part of reverse water distribution reconstruction realizes that 75% of areas of the cooling tower have large air quantity and small air quantity, and the areas with small air quantity have large water quantity. The gas and water in each part of the water distribution in the outer area are basically matched, and the basic performance of the cooling tower is improved to a great extent. This improvement is not a restoration of performance from the previous replacement of new packing and repair of spray device 5. This performance improvement is a reconfiguration of the cooling tower structure and is an improvement over the original design performance.
The utility model discloses the biggest advantage is: the reconstruction cost is low. For a large cooling tower with the diameter of 120 meters, only a water conveying tank with the diameter of 4x30 meters is newly built, and water distribution with the heat exchange area of 75 percent is reconstructed.
Reconstructing 75% of water distribution to obtain;
1. the anti-freezing in winter is realized, and the safety and the economical efficiency of the unit in winter operation are improved.
2. No matter under any working condition, the matching of water, gas and water in the outer area is ensured. And the place with large air quantity has large water quantity. And the water quantity is small in places with small air quantity. The foundation efficiency of the cooling tower is improved.
The thermal power plant reconstructs water distribution of the cooling tower, and the air-water matching tends to be reasonable. The statistical data show that: the temperature of the circulating water discharged from the cooling tower is reduced by 1 ℃, and the coal consumption is averagely reduced by 1 to 1.2 grams/(kilowatt-hour) under the condition of constant other conditions under the same power generation capacity. Taking a 600MW unit as an example: the temperature of the water discharged from the cooling tower is reduced by 1 ℃, and about 250 ten thousand yuan of coal consumption is saved all the year round. The coal cost is saved by 7500 ten thousand yuan in total for 30 years of the whole service life. The coal consumption is reduced by about 3500 tons every year, and the carbon reduction effect is obvious. The investment return and the investment recovery period are reasonable.
