Cooling tower water distribution system modeling method

Abstract

The invention provides a cooling tower water distribution system modeling method. The modeling method comprises the steps that a preliminary arrangement scheme map is read, conversion is carried out on the arrangement scheme map, a cooling tower vertical shaft is simplified into a point, a water distribution groove, a water distribution branch groove and a water distribution pipe are divided into pipe segments, a spraying nozzle, a short pipe and a tee are simplified into nodes, the short pipe and the tee are connected with the spraying nozzle, all the pipe segments are simplified into straight line segments, each pipe segment is numbered from the cooling tower vertical shaft as a starting point, each pipe segment is gone through, a starting node coordinate and a terminal node coordinate of each pipe segment are saved corresponding to the number, attribute information of each pipe segment related to water distribution design is saved, connection relation information of each pipe segment and downstream pipe segments is saved, and data of each pipe segment recorded in the ergodic process are saved in a dataset. The cooling tower water distribution system modeling method can read the cooling tower pipeline arrangement scheme map finished preliminarily in early stage, and forms the dataset as a model of cooling water distribution calculation. Water distribution calculation can be carried out conveniently by utilizing the model.

Description

technical field [0001] The invention relates to water distribution technology, in particular to a modeling method for a cooling tower water distribution system. Background technique [0002] Using cooling tower water distribution system for cooling is widely used in thermal power plants, nuclear power plants and other manufacturers. The design of cooling tower water distribution system is not only related to the cooling effect of the cooling system, but also related to economic benefits. [0003] With the continuous increase of unit capacity, the cooling tower area and cooling water volume are also increasing, and the water distribution design for super-large cooling towers is also becoming more and more complicated. For the cooling tower water distribution system, the basic design requirement is that the water output of each nozzle is basically the same, which is called water distribution uniformity. The larger the scale of the cooling tower, the more nozzles it involves, ...

Problems solved by technology

The larger the scale of the cooling tower, the more nozzles involved, the more complex the pipeline, and the more complex the calculation of water distribution uniformity

[0004] Under the existing technology, the cooling tower water distribution calculation program separates the calculation from the drawing design. When performing the calculation, it takes a lot of time to model the cooling water distribution calculation, and the calculation results need to be manually converted into the design drawings. For super large Cooling tower water distribution calculation, the efficiency of the existing technology makes the enterprise unaffordable
