Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower circulating pumps, and particularly relates to a cooling tower circulating pump convenient for exhausting air. Background Technique

[0002] A cooling tower is a device for reducing the water temperature in thermal equipment. Its cooling principle is to use the contact between water and air flow for heat and cold exchange to generate water vapor, and the heat is carried away through the volatilization of water vapor, so as to cool the heat generated in industry or refrigeration air conditioning to ensure the normal operation of thermal equipment. Its shape is generally barrel-shaped, so it is called a cooling tower. The closed cooling tower circulating pump is an auxiliary equipment that provides a cooling water source for the unit auxiliary equipment to ensure the normal operation of thermal equipment such as steam turbines, boilers, and generators.

[0003] The existing cooling tower circulating pump cannot exhaust air from the circulating pump. A large amount of air accumulates at the inlet of the circulating water pump. If this air enters the impeller, it will cause cavitation of the water pump. The air in the condenser occupies a certain space, reducing the flow area of the circulating water and the cooling area, affecting the cooling effect. At the same time, the air will also generate impact in the pipeline, and in severe cases, it will cause deformation of the end cover of the condenser water chamber.

[0004] In the patent document with the publication number of CN221325149U, an exhaust type closed cooling tower circulating pump is disclosed, which realizes the diversion of the cooling water transported from the cooling tower according to the temperature, thus avoiding the entry of cooling water with too high temperature into the thermal equipment, and realizes the display of the working state of the cooling tower according to the temperature of the cooling water transported from the cooling tower, so as to give a prompt to the maintenance personnel.

[0005] However, when the exhaust type closed cooling tower circulating pump is in use, due to a large amount of air accumulating at the inlet of the circulating water pump, it may cause cavitation of the water pump. The air in the condenser occupies a certain space, reducing the flow area of the circulating water and the cooling area, affecting the cooling effect. Therefore, it is necessary to propose a cooling tower circulating pump convenient for exhausting air. Content of the Utility Model

An air inlet is arranged on one side of the cooling tower. The air inlet can ensure that there is a continuous supply of dry air inside the cooling tower.

[0011] Preferably, one side of the circulating water pump is arranged at the exhaust port. The exhaust port is connected to the air pump.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] Example 1:

[0026] A cooling tower circulating pump facilitating exhaust includes a cooling tower 1 and an exhaust pipe 2 fixedly connected to the top of the cooling tower 1. A cooling mechanism is arranged on one side of the exhaust pipe 2;

[0027] The cooling mechanism includes a cooling fan 201, a motor 202, a cooling pipe 203, a connecting pipe 204, a circulating water path 205, a drain pipe 206, a water pump 207, an output pipe 208, a condensate pipe 209 and a water tank 210. The cooling fan 201 is rotatably connected inside the exhaust pipe 2, the motor 202 is arranged on the top of the exhaust pipe 2, the cooling pipe 203 is arranged on one side of the exhaust pipe 2, and the cooling pipe 203 is set in an inclined state with the left end lower and the right end higher. The water droplets condensed on the inner wall of the cooling pipe 203 will flow downward along the inclined cooling pipe 203, and after flowing to the leftmost end, they can be discharged into the sump 3 through the condensate pipe 209. An installation seat is fixedly connected to the outside of the cooling pipe 203, and the circulating water path 205 is fixedly connected to one side of the installation seat. The circulating water path 205 can take away the heat on the surface of the cooling pipe 203 by continuous water flow. The connecting pipe 204 is arranged on one side of the cooling pipe 203, the circulating water path 205 is arranged outside the cooling pipe 203, the water tank 210 is fixedly connected to the top of the cooling tower 1, the drain pipe 206 and the water pump 207 are arranged on the top of the water tank 210, the output pipe 208 is arranged on one side of the water pump 207, the condensate pipe 209 is arranged on one side of the cooling pipe 203, one end of the condensate pipe 209 is connected to one side of the cooling pipe 203, and the other end is connected to one side of the sump 3. The condensate pipe 209 can collect the cooling water inside the cooling pipe 203 into the sump 3. After starting the motor 202, the cooling fan 201 starts to work, discharging the hot steam inside the cooling tower 1 into the cooling pipe 203. The water inside the water tank 210 is output to the circulating water path 205 and finally input into the water tank 210 through the drain pipe 206, which can dissipate the heat of the cooling pipe 203. When the hot steam contacts the inner wall of the cooling pipe 203, it will condense into water droplets, flow down the inclined surface of the cooling pipe 203 to the condensate pipe 209, and be discharged into the sump 3 by the condensate pipe 209 to recycle the water source.

[0028] Example 2:

[0029] On the basis of the first embodiment, the cooling tower 1 is thus provided with an exhaust mechanism. The exhaust mechanism includes a shunt pipe 101, a nozzle 102, a circulating water pump 103, an air pump 104, an external connection pipe 105, and a packing 106. The shunt pipe 101 is arranged inside the cooling tower 1. The nozzle 102 is fixedly connected to the bottom of the shunt pipe 101. The circulating water pump 103 is arranged on one side of the cooling tower 1. An exhaust port is arranged on one side of the circulating water pump 103, and the exhaust port is communicated with the air pump 104. Before starting, the air pump 104 can be started first to discharge the air inside the circulating water pump 103 to avoid the influence of the remaining air on the system operation. The air pump 104 is arranged on one side of the circulating water pump 103. The external connection pipe 105 is arranged on one side of the circulating water pump 103. The packing 106 is arranged inside the cooling tower 1. The cooling water carrying waste heat is absorbed by the external connection pipe 105 through the circulating water pump 103 and is shunted by the shunt pipe 101 to be discharged from the nozzle 102, and is evenly sprayed on the packing 106. At the same time, it exchanges heat with the dry air entering from the air inlet 4 outside the cooling tower 1, evaporates into the air, and takes away the heat. The cooling water then drips into the water collecting pool 3 at the bottom of the cooling tower 1 and continues to be recycled. During the operation of the circulating water pump 103, an exhaust port communicated with the air pump 104 is arranged on one side of the circulating water pump 103, which can discharge the air inside the circulating water pump 103.

[0030] A water collecting pool 3 is arranged at the bottom of the cooling tower 1. The water collecting pool 3 can collect and recycle the cooling water inside the cooling tower 1 and the cooling water output by the condensate pipe 209. An air inlet 4 is opened on one side of the cooling tower 1. The air inlet 4 can ensure that there is always a continuous supply of dry air input into the cooling tower 1.

[0031] Working principle:

[0032] First of all, through the arranged exhaust mechanism, the cooling water carrying waste heat is absorbed by the external connection pipe 105 through the circulating water pump 103 and is shunted by the shunt pipe 101 to be discharged from the nozzle 102, and is evenly sprayed on the packing 106. At the same time, it exchanges heat with the dry air entering from the air inlet 4 outside the cooling tower 1, evaporates into the air, and takes away the heat. The cooling water then drips into the water collecting pool 3 at the bottom of the cooling tower 1 and continues to be recycled. During the operation of the circulating water pump 103, an exhaust port communicated with the air pump 104 is arranged on one side of the circulating water pump 103, which can discharge the air inside the circulating water pump 103.

[0033] Furthermore, through the provided cooling mechanism, since the evaporation of water inside the cooling tower 1 into the air will not continue indefinitely, as the air humidity increases and the air on the water vapor contact surface reaches saturation, water molecules cannot evaporate. At this time, the cooling fan 201 needs to play a role. After starting the motor 202, the cooling fan 201 starts to work, discharging the hot steam inside the cooling tower 1 into the cooling pipe 203. After starting the first water pump 207, the water inside the water tank 210 is output to the circulating water path 205 and finally input into the water tank 210 through the drain pipe 206, which can dissipate heat from the cooling pipe 203. When the hot steam contacts the inner wall of the cooling pipe 203, it will condense into water droplets, flow down the inclined surface of the cooling pipe 203 to the condensate pipe 209, and finally be discharged into the sump 3 through the condensate pipe 209, realizing the recycling of the water source.

[0034] Furthermore, the air inlet 4 provided on the side of the cooling tower 1 can continuously supply dry air to the inside of the cooling tower 1, providing a constant dry air flow.
