Problems solved by technology
[0002] Existing cooling towers generally use electric motors to drive the fan of the cooling tower. There is a certain height difference between the water flow entering the tower and the ground, and the pressure difference in this part is wasted. Moreover, due to the inaccurate estimation of the hydraulic loss of the system in the design, and the consideration of Due to various factors such as reliability in the process of manufacturing and use, the return water of cooling tower circulating water has a small amount of excess head and flow rate. For this kind of return water, the current practice is to make it all go through the valve to reduce the pressure and then send it to the cooling tower system for cooling , the residual pressure of the circulating water is completely unused

A cooling tower circulating water excess pressure utilization device comprises a water inlet pipeline which is communicated with a water inlet of a hydraulic turbine that is installed on a bearing support; a water outlet of the hydraulic turbine is communicated with a water outlet pipeline; a main shaft of the hydraulic turbine is connected with a generator through a coupler and a transmission shaft; the hydraulic turbine is of a rear shaft extension cross flow type structure, wherein a shell body is an elbow; one end of the shell body is provided with the water inlet and the other end of theshell body is provided with the water outlet; an impeller component is arranged in the shell body at one end of the water inlet; and one end of the main shaft is connected with the impeller componentand the other end of the main shaft extends out of the shell body and then is connected with the generator through the coupler and the transmission shaft. The cooling tower circulating water excess pressure utilization device has the advantages of energy conservation, no environment pollution, simple structure and easy installation, is suitable for being promoted, and can also be used in other water systems with differential pressure except being used in the cooling tower circulating water system.
Description
technical field [0001] The invention relates to an energy-saving device, in particular to a device for generating electricity by utilizing the residual pressure of circulating water in a cooling tower. Background technique [0002] Existing cooling towers generally use electric motors to drive the fan of the cooling tower. There is a certain height difference between the water flow entering the tower and the ground, and the pressure difference in this part is wasted. Moreover, due to the inaccurate estimation of the hydraulic loss of the system in the design, and the consideration of Due to various factors such as reliability in the process of manufacturing and use, the return water of cooling tower circulating water has a small amount of excess head and flow rate. For this kind of return water, the current practice is to make it all pass through the valve to reduce the pressure and then send it to the cooling tower system for cooling , the residual pressure of the circulati...
