Abstract

The invention provides a water-rock chemical dynamic reaction double-system test unit, belonging to the technical field of water-rock chemical dynamic testing. The test unit can effectively solve the problem of water-rock chemical actions of the simulated rock samples and various adjustable reaction condition launching solutions. The test unit is divided into three parts: a high-pressure gas cylinder is connected with a reactor with a closing bolt through a high-pressure gas pipeline, and an electromanometer and a pressure meter are arranged in the high-pressure gas pipeline; a solution storage unit is connected with the reactor through a pipeline which is provided with a valve and a flow rate monitor; the bottom of the reactor is provided with a reticular stand, and a stirring motor with a magnetic stirring rotor is arranged under the reticular stand; the upper shoulder of the reactor is provided with a butterfly bolt and five plug holes which are respectively provided with an acidimeter, a water sampler, a dissolved oxygen meter, a conductivity meter and a potentiometer; and a water outlet pipeline is provided with a valve and a flow rate monitor. The test unit is mainly used for water-rock chemical dynamic reaction testing.

Description

technical field [0001] The invention belongs to the technical field of water-rock chemical dynamics, in particular to the simulation test technology of water-rock chemical dynamics. Background technique [0002] The chemical interaction of water and rock is a very important factor affecting the weathering process of surface rocks. Because the reaction mechanism is very complex and can significantly change the engineering properties of rock mass, it has long attracted the attention of scholars all over the world. The traditional water-rock interaction simulation mainly studies various geochemical reactions between water and minerals in various water-rock interaction systems and under different environmental conditions from the perspective of chemical thermodynamics. Under natural conditions, a large number of geological facts reflect that the chemical interaction of water and rock is often unbalanced, which is related to the kinetic reaction rate of water-rock interaction und...
