Description
Technical Field
The utility model relates to a heat exchange equipment technical field especially relates to a low wind pressure closed cooling tower against current.
Background
The countercurrent closed cooling tower is a relatively wide cooling tower product in the market at present, and has the working principle that a cooler is arranged at the upper part of the whole tower, an air inlet is arranged at the lower part of the whole tower, a fan is arranged at the top of the tower, and a water collecting tank and a spray water pump are arranged at the bottom of the cooling tower. The operation flow of the whole tower is that a fan arranged at the top of a cooling tower continuously introduces air into the tower, a spray water pump continuously conveys cooling circulating water in a water collecting tank to a spray water pipe arranged at the upper part of a cooler, the spray water pipe continuously sprays the cooling circulating water on the cooler, hot fluid in the pipe and spray water outside the pipe in the cooler perform evaporation and convection heat exchange on the air, and therefore the heat of the fluid in the pipe is taken away. After heat exchange, the spray water still drops for a certain distance to continue temperature reduction until the spray water drops into the water collecting tank.
Because the spray water of the countercurrent closed cooling tower completely depends on air evaporation to take away heat, the quantity of the coils required by the countercurrent closed cooling tower is large, and therefore the air can generate large static pressure inside the cooling tower after passing through the large number of the coils. Therefore how effectual reduction is heat resistance of closed cooling tower against current to can effectual improvement amount of wind, reduce the area and the heat exchanger tube bundle of cooling tower, improve the heat transfer performance of cooling tower, be the problem that awaits a solution at present, based on this, we propose a low wind pressure closed cooling tower against current.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a low wind pressure countercurrent closed cooling tower.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a low wind pressure closed cooling tower against current, includes the body of the tower, be provided with cooling blower, evaporation zone cooler, air inlet grid, water catch bowl and convection current section cooler on the body of the tower respectively, water catch bowl one side is through pipeline fixedly connected with spray water pump, spray water pump output end fixedly connected with sprays the water distributor, a plurality of shower nozzles have been seted up to spray the water distributor front end face is fixed, the fixed setting of convection current section cooler is inside the water catch bowl.
Preferably, the cooling fans are arranged in a plurality, and the cooling fans are uniformly distributed above the evaporation section cooler.
Preferably, the air inlet grille is fixedly arranged between the evaporation section cooler and the convection section cooler.
Preferably, the upper-section pipe body of the spraying water distribution pipe is arranged above the evaporation section cooler.

Compared with the prior art, the beneficial effects of the utility model are that:
1. in the utility model, a part of the cooler arranged above the air inlet in the existing device is arranged in the water collecting tank at the bottom, so that the ventilation resistance of the cooling tower is obviously reduced, and the air quantity can be increased by 0.5-1 time, thus the heat exchange performance of the cooling tower can be effectively improved, and the better heat exchange effect can be obtained while the heat exchange area is reduced;
to sum up, the utility model discloses overall structure designs more rationally, and the heat transfer effect is compared traditional device and is better, can effectively improve the heat exchange efficiency of cooling tower.
Drawings
Fig. 1 is a schematic diagram of a main structure of a low wind pressure counter-flow closed cooling tower provided by the present invention.
In the figure: 1. a tower body; 2. an evaporation section cooler; 3. an air inlet grille; 4. a water collection tank; 5. a convection section cooler; 6. spraying a water distribution pipe; 7. a spray water pump; 8. a spray head; 9. and (6) a cooling fan.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, a low wind pressure countercurrent closed cooling tower comprises a tower body 1, wherein a cooling fan 9, an evaporation section cooler 2, an air inlet grille 3, a water collecting tank 4 and a convection section cooler 5 are respectively arranged on the tower body 1, one side of the water collecting tank 4 is fixedly connected with a spray water pump 7 through a pipeline, the output end of the spray water pump 7 is fixedly connected with a spray water distributor 6, a plurality of spray nozzles 8 are fixedly arranged on the front end face of the spray water distributor 6, liquid in the water collecting tank 4 is pumped into the upper half section of the spray water distributor 6 through the spray water pump 7 and then is sprayed out from the spray nozzles 8, the convection section cooler 5 is fixedly arranged inside the water collecting tank 4, forced convection heat exchange is carried out through the spray water and the convection section cooler 5, and the temperature of fluid in the pipe is further reduced.
Wherein, cooling blower 9 is equipped with a plurality ofly altogether, and a plurality of cooling blower 9 evenly distributed sets up in evaporation zone cooler 2 top.
Wherein, the air inlet grille 3 is fixedly arranged between the evaporation section cooler 2 and the convection section cooler 5.
Wherein, the upper pipe body of the spray water distribution pipe 6 is arranged above the evaporation section cooler 2, and spray water sprayed from the spray head 8 is uniformly sprayed on the evaporation section cooler 2 for cooling.
Wherein, a plurality of shower nozzles 8 evenly distributed are arranged on the spray water distributor 6, so that the spray water is more even.
Wherein, the evaporation section cooler 2 and the convection section cooler 5 are communicated through a pipeline, and the two are communicated with each other.
The working principle is as follows: the device is with traditional cooler split for evaporation zone cooler 2 and convection current section cooler 5, can obtain littleer degree of approximation when getting into water catch bowl 4 through the body of the tower 1 mesocycle shower water after optimizing, the difference of temperature and air wet bulb temperature, because the reduction of the number of piles of evaporation zone cooler 2 makes the body of the tower 1 wind pressure reduce, the amount of wind has obtained great promotion, and the whole submergence of convection current section cooler 5 is in water catch bowl 4, spray water pump 7 drives the shower water motion, the shower water takes place the forced convection heat transfer with convection current section cooler 5 this moment, further with intraductal fluid temperature reduction, thereby reach higher heat transfer effect.
