Abstract

The invention discloses a heating well layout optimization method and device based on a genetic algorithm, and the method comprises the steps of obtaining the shape and area of a target region, and dividing the target region into a plurality of regular blocks according to a segmentation rule; distributing k heating wells evenly on each regular block according to the arrangement rule as an initial group P (0); setting an evolutionary algebra counter t = 0, and setting a maximum evolutionary algebra T; assuming that k heating wells have the probability of p in each circulation and move along a random direction around the k heating wells; calculating the new position coverage area of the P (t) k heating wells after movement, and taking the scheme with the maximum coverage area as the scheme P (t+1) of the next generation; when t is equal to T, determining that the current corresponding scheme is the relatively optimal layout scheme. According to the method, the layout of the heating wells in a thermal strengthening SVE process is optimized, overlapping of the action range of the heating wells is reduced, the effective area covered by the heating wells is maximized, and therefore the purposes of reducing energy waste and controlling greenhouse gas emission are achieved.

Description

technical field [0001] The invention relates to the technical field of gas phase extraction, in particular to a genetic algorithm-based heating well layout optimization method and device. Background technique [0002] Gas phase extraction (SVE) is a widely used soil in-situ remediation technology. Its principle is to use heating wells to heat the surrounding soil, and then blow a large amount of gas into the soil or extract the gas from the soil, thereby causing soil damage. gas flow in the . Using this method, the volatile and semi-volatile organic compounds in the soil can be effectively removed. [0003] However, my country's SVE technology started late and its development lagged behind. It mostly stayed in single-factor experiments, shallow mechanism and dynamic model research. The technology in related fields started late, and its independent research and development capabilities were backward, making it difficult to form a scale effect. In particular, there are very ...
