Device for simulating influence of solute diffusion into medium in pipeline

Abstract

The invention discloses a device for simulating the influence of the solute diffusion into a medium in a pipeline. The device comprises a water inlet device, a sand box, a drainage device, an electriccontrol cabinet and a height adjustment device. The sand box is an opened box body, the inside of the sand box is separated into a water inlet zone, a medium filling zone and a drainage zone, and liquid flows among the three zones. An inner wall of the sand box is provided with an upper pipe and a lower pipe, and an outer wall is provided with a pressure sensor. The water inlet device comprises first, second and third water inlet boxes with the same structure, and the first, second and third water inlet boxes communicate with water inlet pipelines of the upper pipe, the lower pipe and the sand box. The drainage device comprises first, second and third drainage boxes with the same structure, and the first, second and third drainage boxes are respectively connected to water outlet pipelinesof the upper pipe, the lower pipe and the sand box. The height adjustment device includes an adjustment seat for adjusting the height of each water inlet box and each drainage box. The device of theinvention can simulate the groundwater flow movement of double pipelines and the medium and water quantity exchange and solute transport processes, and therefore, the mutual influence relationships between the pipelines and the medium and between the two pipelines are studied.

Description

technical field [0001] The invention relates to a device for simulating the migration process of pollutants in groundwater in karst areas, in particular to a device for simulating the influence of solute in a pipeline on diffusion to a medium. Background technique [0002] The karst area in Southwest my country is rich in groundwater resources. Atmospheric precipitation and surface water can be directly poured into the ground through sinkholes, etc., making groundwater resources easily polluted, difficult to develop and difficult to manage. Therefore, it is particularly important to protect and improve the existing water quantity and water quality. . The karst pipeline interaction zone is the zone where the pipeline water interacts with the surrounding karst medium water. It belongs to the material exchange inside the aquifer and undergoes active hydrological, geochemical and biological interactions, which can significantly promote the degradation of pollutants and promote th...

Problems solved by technology

With the in-depth study of karst water-bearing media, the numerical simulation technology of karst water has been continuously developed. The physical model stage of a single pipeline and medium, and because the pipeline system in karst areas is complex and changeable, and the pipeline network has many branches, further research is needed on the physical model of the exchange process of water flow and solute between multiple pipelines and media
