Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Embodiment 1 biological column leaching testing apparatus
As shown in Figure 1, biological column leaching testing apparatus comprises Bioleaching post and dip circulation system.Bioleaching post 1 outer layer covers has zone of heating 3 and thermal insulation layer 4, and post upper end sets out pore 10, solution inlet port 11 and solution spraying device 2, and post lower end is inflation inlet 6 and solution catcher 7.The zone of heating of Bioleaching post is coil electrically heated, and thermal insulation layer is aerosil thermal insulation layer.As shown in Figure 2, solution spraying device 2 is downward opening umbrella-shaped structure, and umbrella cover distributes multiple through hole.Solution catcher top and Bioleaching post junction 701 are porous plate, and its underpart is connected with liquid-collecting barrel 8.Liquid-collecting barrel 8 is wrapped with thermal insulation layer 801, and liquid-collecting barrel top arranges insulation cover 803, and insulation cover 803 is provided with liquid outlet 805, fluid inlet 804 and inlet mouth 802.Fluid inlet 804 connects solution catcher 7, and solution catcher 7 and liquid collecting bung 803 are structure as a whole.Liquid outlet 805 is connected with peristaltic pump 5, and peristaltic pump 2 is connected to the solution spraying device 2 of Bioleaching post by transport pipe, by solution pump to capital end, forms dip circulation.
Thermal insulation layer 4 adopts aerosil lagging material, and this material is one of heat-insulating property best material up to now, and thermal conductivity is less than 0.015w/mk (70 DEG C).Adopt this lagging material, for the Bioleaching post of φ 200mm × 1800mm, the lagging material that parcel 10mm is thick, even if post internal-external temperature difference reaches 40 DEG C, heat radiation hourly is only 121.5J, and heat radiation every day is 2916J, can play good insulation and simulate effect.
