Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
Siphon balanced type heavy metal contaminants stripping-adsorption test device, its structure as shown in Figure 1, forms primarily of parts such as constant temperature oven 9, stripping pipe 3, adsorption tube 10, triangle overflow exhaust pipe 6, aspiration pumps 5.
During on-test, the test specimen taking certain mass is placed in stripping pipe 3, opens aspiration pump 5 and makes whole system be full of solution.Triangle overflow exhaust pipe 6, stripping pipe 3, adsorption tube 10, feed liquor vessel 1 and sampling injection needle tube 8 are all placed in constant temperature oven 9, so that test remains on a stationary temperature.Triangle overflow exhaust pipe 6 is perpendicular to horizontal plane, and its three tops connect stripping pipe 3, adsorption tube 10 and aspiration pump 5 respectively.Top connects stop valve 4 to aspiration pump 5, its opposite side level.Side connects stripping pipe 3, and opposite side connects adsorption tube 10, and makes stripping pipe 3 and adsorption tube 10 arranged in parallel, and the design of hydrocone type effectively can reduce the height of cylinder, makes it easily to be placed in constant temperature oven, reduces the pressure of fluid column itself simultaneously.There is individual T-valve 7 in the middle of the horizontal tube of connection stripping pipe 3 and adsorption tube 10, connect sampling injection needle tube 8.
Side, triangle overflow exhaust pipe 6 base angle connects stripping pipe 3, and liquid feed valve 2 is installed in stripping pipe 3 lower end, puts the feed liquor vessel 1 for depositing stripping test sample solution below.The opposite side at triangle overflow exhaust pipe 6 base angle connects adsorption tube 10, and liquid valve 11 is installed in adsorption tube 10 lower end, is put by fluid vessel 12 below in constant temperature oven 9 outside.
Like this, when testing feed liquor, open liquid feed valve 2 and stop valve 4, closedown liquid valve 11 and sampling T-way valve 7, start aspiration pump 5, and by adjustable cut-off valve 4 speed control, exceed after leg-of-mutton horizontal tube until liquid, point inflow adsorption tube 10.After adsorption tube 10 is full of, before liquid arrives apex, close stop valve 4.Close whole valve afterwards, leach under waiting for stationary state.After a period of time, open liquid feed valve 2 and liquid valve 11, other valve closings.Utilize liquid valve 11 regulates liquid flow, in observable certain hour, fluid drips the size that number carrys out adjust flux.Observable, the solution taken out in fluid vessel 12 measure the water soluble characteristic of material waste material under uniform temperature, certain pH value containing heavy metal.
