Combined tubular high-pressure seepage leaching test device

Abstract

The invention relates to a combined tubular high-pressure seepage leaching test device. The device comprises a high-pressure storage tank, one or more combined tubular reactors are arranged in the high-pressure storage tank, every combined tubular reactor is filled with leaching ores, every combined tubular reactor is formed by splicing and assembling a plurality of tubular body units, a monitoring section is formed at every joint of the tubular body units, pH sensors are arranged in the tube body of a short filter unit on the pH monitoring section, OPR sensors are arranged in the tube body ofa short filter unit on the OPR monitoring section, pressure sensors are arranged in the tube body of a short filter unit on the pressure monitoring section, dissolved oxygen sensors are arranged in the tube body of a short filter unit on the dissolved oxygen monitoring section, and temperature sensors are arranged in the tube body of a short filter unit on the temperature monitoring section. Thedevice can be used to carry out the uranium ore leaching process test of a liquid-solid two-phase reaction under a one-dimensional flow seepage condition and the uranium ore leaching process test of ahigh-pressure (CO2 + O2)-liquid-solid three-phase reaction under a one-dimensional flow seepage condition.

Description

technical field [0001] The invention relates to the field of leaching tests, in particular to a combined tube type high-pressure seepage leaching test device. Background technique [0002] The uranium ore leaching experiment is mainly to detect the substance of uranium ore. During the reaction, the data in the reactor (such as pH, temperature, OPR, pressure) needs to be monitored in real time. The current reactor is monitored through a single group of experiments. Now In existing technologies, there is often no dedicated online multi-data monitoring system, and the precision of the leaching test is not high. [0003] For this reason, this application designs a brand-new leaching test device, which is a custom-made product according to specific test requirements. This test device can be used to carry out uranium ore leaching under the condition of one-dimensional flow and seepage flow. Process test, high-pressure CO under the condition of one-dimensional flow and percolation...
