Abstract

The invention discloses an artificial simulation climate box for monitoring uranium tailing sand. The artificial simulation climate box comprises an artificial climate box body with a columnar box body structure, an artificial rainfall simulation system, an illumination and temperature and humidity control system and a radon measurement module; the artificial climate box body comprises a soil sample placing area at the bottom end and a radon collecting cover above the soil sample placing area; the radon collecting cover is in circular sampling connection with the radon measurement module through a gas guide pipe; the artificial rainfall simulation system comprises a water storage tank and an atomizing nozzle connected to the water storage tank; the atomization nozzle is fixedly installed in the radon collection cover, rainfall simulation is achieved by controlling the flow of the atomization nozzle, the illumination and temperature and humidity control system is composed of a constant-temperature water bath interlayer and a xenon long-arc lamp, control and adjustment of the temperature of the system are achieved, and a ventilation module and a program control system are additionally arranged to improve operation convenience and safety controllability. By means of the above structural design, operators can analyze radon precipitation more safely, conveniently and accurately whensimulating natural conditions.

Description

technical field

[0001] The invention relates to an experimental simulation device for the migration law of pollutants, which belongs to the field of environmental protection, in particular to an artificial simulated climate box for monitoring uranium tailings sand. Background technique

[0002] With the large-scale application and development of nuclear power technology, the mining, processing and production activities of nuclear fuel are becoming more and more active and extensive. The nuclear fuel currently used is mainly uranium fuel rods, which promotes the mining of uranium ore; along with the mining of uranium ore, A large number of uranium waste rocks and uranium tailings are inevitably left behind; up to now, the world's uranium waste rocks have reached more than 40 billion tons, and uranium tailings have reached more than 20 billion tons. Causes extremely serious radiation pollution problems; uranium tailings mainly cause harm to the public and the environment throu...
