Management and utilization system of environmental wind of cooling tower

Abstract

A management and utilization system of environmental wind of a cooling tower relates to a system for managing and utilizing environmental crosswind around the cooling tower of a thermal power plant wet cooling unit. A device of the system is composed of guide plates, a guide plate separation membrane, a communicated wind collecting pipe (or an air bellow), an inlet check valve, a wind distribution pipeline and a hood. The management and utilization system uses the guide plates to divide an exhaust inlet of the cooling tower into two areas. An inner area is surrounded and protected by the guide plate 2 to be capable of being matched with an air inlet of the cooling tower to build a stable air inlet flow field. An outer area is divided into a plurality of guide zones by using a middle separation plate between the guide plate 2 and the guide plate 1 according to needs, and wind coming from the outer area is guided by the guide zones to be led in the wind collecting pipe (or the air bellow) through the check valve designed on the wind collecting pipe (or the air bellow). A check valve on a leeward or crosswind face is closed, wind in the wind collecting pipe (or the air bellow) serves as motive power airflow to be blown to a raining area in the cooling tower through the wind distribution pipeline, and the hood at a port of the wind distribution pipeline prevents circulating water from dropping in the wind distribution pipeline.

Description

technical field [0001] The invention belongs to the field of thermal power generation, and in particular relates to a system for managing and utilizing crosswinds in the surrounding environment of cooling towers of wet cooling units. Background technique [0002] The cooling tower is the key equipment of the wet-cooling unit of the thermal power plant, and it is a necessary condition to establish the vacuum of the steam turbine and take away the heat source of the cold end. However, due to the existence of environmental crosswinds and the uncontrollability of its direction and wind speed, it has brought great challenges to the economical, safe and stable operation of the unit. [0003] For wet-cooling units, Belarus and Shandong University in China have conducted a lot of research, and concluded that the existence of crosswinds leads to uneven air intake in the cooling tower, and produces longitudinal vortices inside the cooling tower, resulting in reduced air intake and poo...
