Abstract

The invention discloses a temperature difference power cooling tower based on a screw expander. The temperature difference power cooling tower comprises a cooling tower body, fan blades, a water tank, a spraying device, an evaporator, a driving device, a condenser, a pump and a power source; the driving device comprises a hybrid power box and the screw expander, the power source is connected to a first input shaft of the hybrid power box, the screw expander is connected to a second input shaft of the hybrid power box, and an output shaft of the hybrid power box is connected to the fan blades; the evaporator is installed in a water inlet pipe, an outlet of the evaporator is connected to a steam inlet of the screw expander through a first pipeline, an outlet of the screw expander is connected to the condenser through a second pipeline, the condenser is connected to an inlet of the evaporator through a third pipeline, the pump is arranged on the third pipeline, and the water inlet pipe is connected to a hot water end. According to the temperature difference power cooling tower, discharged hot water of the cooling tower can be recycled, so that the energy is saved; through dual-power driving, the cooling efficiency is improved, and the problem that power is insufficient due to a single power source can be avoided.

Description

technical field [0001] The invention relates to the technical field of cooling towers, and more specifically relates to a thermodynamic cooling tower based on a screw expander. Background technique [0002] At present, cooling towers are divided into two types: packing type and non-filling type. Nozzles are set above the tower, and the cooling liquid is sprayed from top to bottom; Cool air is drawn from the bottom up. [0003] The fan in the prior art is driven by the water turbine, that is to say, the rotation of the water turbine is driven by the water flow, and then drives the fan to work. The degree of cooling treatment of the cooling water by the cooling tower is closely related to the speed of the fan. The power is limited by the flow rate and the size of the water head. At this time, the power of the water turbine cannot be further increased. When the water flow rate or water head entering the turbine is too small, the power of the turbine is insufficient, and the s...
