Recyclable leaching device for leaching experiment

Abstract

The invention relates to a recyclable leaching device for a leaching experiment. The recyclable leaching device mainly comprises a sample loader, a water storage device, a pipeline, a partition board, a spray thrower, a water regulating valve, a water level sensor, a water compensating tank, a fixed bracket and the like. The recyclable leaching device is particularly applied to the leaching experiment of solid waste including coal gangue, coal ash, abandoned mines, tailings, gangue, industrial solid waste, municipal solid waste and the like. The recyclable leaching device is used for simulating leaching conditions of the solid waste in water and possible influences to the water body and the soil environment. The recyclable leaching device is simple, practical and convenient to operate. According to the recyclable leaching device, ideal leaching simulation test basic data can be provided to the selection of piling, filling and pouring processes of the solid waste and the influences of the solid waste to the environment.

Description

Technical field [0001] The invention relates to a recyclable leaching device for leaching tests, which can be used for solid waste, especially coal gangue, fly ash, tailings, abandoned minerals, gangue, industrial solid waste, urban solid waste, etc. It belongs to the field of solid waste treatment and resource utilization. Background technique [0002] With the sustained and stable development of the national economy, my country's mining industry has developed rapidly, and the mining volume of coal, metals, and non-metallic minerals has continued to increase, and a large amount of coal gangue, tailings, and abandoned minerals have been discharged correspondingly; the large-scale combustion and utilization of coal has also produced Lots of fly ash. On the other hand, the urbanization process is accelerating, and more and more domestic waste is discharged. All of these make the discharge of solid waste more and more. Many coal gangue, tailings, and abandoned minerals are di...

Problems solved by technology

It not only occupies a large area of ​​land and affects the ecological landscape, but also may cause serious harm to water bodies and groundwater after being leached by media such as rainwater or groundwater, and an impact assessment is urgently needed

[0003] At present, although there are leaching test devices for tailings such as coal gangue, most of them are operated by manual water injection, and there are certain uncertainties in the amount and level of leaching water, and most of them can only be leached once and cannot be repeated. The cycle test is not only cumbersome to operate, but it is often difficult to make an objective and accurate evaluation of the leaching and leaching of components in tailings and gangue due to the lack of regularity of water injection, which greatly affects the accuracy of the test and the accuracy of the results. objectivity and repeatability
