Abstract

The invention discloses a cooling tower. A body of the cooling tower is formed by sequentially sheathing a graphite barrel (1), a graphite heat exchange tube (2) and a graphite tube plate (3); an upper cover plate (4) is arranged at the top end of the tower body, a lower cover plate (5) is arranged at the bottom of the tower body, the graphite barrel (1) is externally covered by a steel shell (6) which is internally filled with cooling water, and the graphite heat exchange tube (2) and the graphite tube plate (3) are both immersed into the cooling water. For the cooling tower provided by the invention, the graphite tube plate and the graphite heat exchange tube are machined by a lathe and then immersed into a phenolic resin impregnant to be treated, so that the graphite tube plate and the graphite heat exchange tube have the same coefficient of thermal expansion and meanwhile, the purpose of impermeability is achieved; the graphite heat exchange tube and the graphite tube plate are in threaded connection, so that the high temperature resistance performance of graphite material is greatly improved.

Description

technical field [0001] The invention relates to the field of heat exchange equipment, in particular to a cooling tower capable of meeting the high-temperature intake air temperature. Background technique [0002] The cooling tower is a traditional heat exchange device, and its working principle is to use the air flowing from the bottom up to cool the water flowing from the top down. The main function of the cooled water is to send it to the condenser to condense the steam that has done work in the steam turbine into water and then send it back to the boiler for heating. Without this cooling tower, the steam cannot be condensed into water and sent back to the boiler, the thermodynamic cycle for power generation cannot be established, and the working medium cannot be recovered. The heat exchange tube is the core component to realize heat exchange in the cooling tower. It is a tubular structure. The inside of the tube body is filled with high-temperature gas, and the tube body...
