Detailed Description
The following describes the cooling device of the ventilating and cooling water curtain of the substation in further detail with reference to the accompanying drawings and specific embodiments.
The ventilation cooling water curtain cooling device for the substation as shown in the attached drawing 1 comprises a wall type axial flow fan 1 arranged on one side of a wall body 10 of the substation, a wall body hollow-out cavity 2 is formed in the other side of the wall body 10 of the substation, a cooling water curtain 3 is arranged on the outer side of the wall body hollow-out cavity 2, a cooling water spray head 7 is arranged at the top of the cooling water curtain 3, a buffer water tank 5 is arranged at the bottom of the cooling water curtain, the lower portion of the buffer water tank 5 is connected with a spiral heat exchange tube 4, the other end of the spiral heat exchange tube 4 is connected with the cooling water spray head 7 through a pipeline, a pipeline pump 8 is arranged between the spiral. A window type static pressure box 6 is arranged in the wall hollow cavity 2, and an air outlet of the cooling water curtain 3 is communicated with an air inlet of the window type static pressure box 6. The buffer water tank 5 is connected with a water replenishing pipe 13, so that circulating water can be replenished to the buffer water tank 5. A plurality of porous corrugated water baffles 11 are arranged in the window type static pressure box 6. A single-layer louver opening 12 is arranged at the air outlet of the window type static pressure box 6. A one-way water valve 15 is arranged on a water pipe at the outlet of the pipeline pump 8.
