Problems solved by technology

At present, the cooling tower implements the water distribution method from the inside to the outside. In winter, the reduction of the water volume may cause some areas outside the cooling tower inner filler to be insufficiently equipped with water, which cannot make full use of the characteristics of the large peripheral air flow, and maximize the cooling tower. cooling performance
Moreover, in winter, the air inlet is the most common and the most likely place to freeze. If there is no water flow in the peripheral water distribution pipe, the low temperature will cause the cooling tower to freeze, which will affect the working efficiency of the cooling tower.
[0005] At present, the water distribution system of the cooling tower does not have an external measurement system, and it is impossible to obtain the real-time wind direction, wind speed and other influencing factors of the environmental crosswind. Water spray density in each area of ​​the tower

Abstract

The invention discloses a cooling tower real-time dynamic water distribution system and method based on a non-uniform spraying device. A central round vertical well is used. A main water pipe used for conveying water from the central round vertical well to the periphery of a tower in a pipe type water distribution mode is in a double-layer design and includes an inner pipe body and an outer pipe body. Water flows into a peripheral round pipe from the inner pipe body and then flows towards the center of the tower from the periphery of the tower, and the characteristics that outer zone water spraying density is large and inner zone water spraying density is small are represented. The wind direction and wind speed of environment side wind are monitored online through a wind direction and wind speed detection device arranged outside a cooling tower, and the opening degrees of electric valves corresponding to all zones are adjusted in real time, so that the water distribution amount is changed. Meanwhile, the work state of a micro stepping motor and the baffle directions of non-uniform spraying discs arranged at the edges of all fan-shaped areas are adjusted, spraying in different directions is realized for the different areas, the water spraying density of each area in the cooling tower can be controlled, and coupling of the water distribution uniformity and the air dynamic field inside the cooling tower under the influence of the side wind is realized through real-time dynamic partitioning water distribution.

Description

technical field [0001] The invention relates to a real-time dynamic water distribution system and method for a cooling tower based on a non-uniform splashing device. Background technique [0002] The cooling tower is an important equipment of the cold end system of the power station, and its cooling efficiency affects the efficiency of the entire thermal system. The uniformity of water distribution in cooling towers is closely related to the cooling efficiency. Affected by the side wind of the environment, the aerodynamic field in the cooling tower often has short-circuit problems in the dry area of ​​the airflow. Keeping the air-water ratio throughout the tower consistent is the principle of water distribution optimization. [0003] The ambient crosswind has a great influence on the cooling effect inside the cooling tower, so the water spray density inside the cooling tower is adjusted according to the real-time direction and size of the crosswind, so that the water distri...
