Abstract

The invention discloses a method for determining a variable cross-section pipe distribution mapping relation, which comprises the following steps of: S1, adopting an artificial potential function method to quantify the mapping relation, and defining a potential energy state function when a pipeline or a heat exchange pipe passes through a space; the mapping relation is quantified by adopting an artificial potential function, the target of random search is to enable a potential energy state function to take a minimum value, and at the moment, the corresponding mapping relation is a potential selectable distribution mapping scheme. The method is mainly used for determining a pipe distribution scheme of dense pipelines or heat exchange pipes in special-shaped equipment, and compared with a traditional mode of manually setting the mapping relations of the pipelines or the heat exchange pipes one by one, the pipe distribution efficiency can be effectively improved by adopting an artificial potential function method and a genetic algorithm or other random search algorithms, and the pipe distribution efficiency is improved. Through random search in the mapping space, an optimal mapping relation scheme can be obtained.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and particularly relates to a method for determining a mapping relationship of variable-section pipe layout. Background technique [0002] In special-shaped equipment, such as heat exchangers, reactors or confined spaces, dense pipes or heat exchange tubes are required to pass through transition connections from spaces with different cross-sectional shapes, such as figure 1 As shown in the figure, in the limited transition space, three requirements must be met, the first is no interference, the second is to maintain a certain tube spacing, and the third is to reduce the tube length. Some projects also require that the pipes or heat exchange pipes connecting the two ends of the transition have different arrangements. For example, a certain type of methanol synthesis tower has a triangular and circular arrangement in the middle section. figure 2 shown, and the end section is four circl...
