Description
Technical Field
The invention belongs to a liquid level exchanger, and particularly relates to a temperature-adjustable liquid level exchanger.
Background
Landfill disposal is the main method for disposing municipal solid waste at present. To prevent contamination of groundwater and soil around a landfill, modern landfills are often impervious with a compacted clay liner. However, the compacted clay backing layer is a porous material that may not completely prevent the outward diffusion of landfill leachate. Under the action of the hydraulic gradient, the landfill leachate can migrate outwards through the compacted clay liner. To evaluate the barrier properties of the compacted clay backing layer against landfill leachate, it is necessary to determine the permeability coefficient of the compacted clay backing layer.
Currently, the permeability coefficient of a compacted clay liner is mainly determined by using a flexible wall permeameter. In order to avoid the control panel of the flexible wall permeameter from being polluted by the landfill leachate during the measurement process, the flexible wall permeameter must be provided with a liquid level pressure exchanger. However, the existing liquid level pressure exchanger can only realize the pressure transmission between the water and the landfill leachate interface, and cannot adjust the temperature of the landfill leachate.
In fact, in real landfill sites, the temperature of landfill leachate is constantly changing along with the change of seasons and landfill time; the constant change in temperature will change the viscosity of the landfill leachate and will ultimately affect the permeability coefficient of the compacted clay backing layer.
Based on the above analysis, it is necessary to design a liquid level exchanger with a temperature adjusting function, which can accurately control the temperature of landfill leachate in the permeation test process, thereby realizing the accurate determination of the permeation coefficient of the compacted clay liner layer.
