Description
Technical field
The utility model relates to earth pillar leaching measuring technology, belongs to heavy metal-polluted soil Migration Simulation device, particularly controllable temperature earth pillar Leaching Experiments device.
Background technology
Earth pillar Leaching Experiments is widely used in the research fields such as agricultural, forestry, water conservancy, environment.Application earth pillar Leaching Experiments can test hydrologic process and contaminant transportation rule in lab simulation soil.Underground coal fire is the typical environment problem of association Coal Resource Development, it is a large amount of coal resources of combustible loss not only, also produce material impact to regional environment, coal fire burning pollutant is wherein one of core content of coal fire environmental influence research at the Transport of soil environment.Previous existing earth pillar heating arrangement is only made up of constant temperature oven, only soil column need be placed in constant temperature oven and can carry out simulated experiment, but, its structure is unreasonable, for flame range, its true soil environment temperature is also non-constant, effectively can not provide the thermograde environment close to actual conditions to upper part soil column.
Summary of the invention
The purpose of this utility model is to provide a kind of controllable temperature earth pillar Leaching Experiments device, its structure is more reasonable, effectively can provide the thermograde environment close to actual conditions to upper part soil column, the temperature background of accurate analog flame range soil, resolves for flame range heavy metal-polluted soil and the accuracy of migration research develops skill guarantee.
The purpose of this utility model is achieved in that a kind of controllable temperature earth pillar Leaching Experiments device, comprises the electric heater unit of controllable temperature; Also comprise cylindrical heat transfer case, cylindrical glass cartridge, hard gland bonnet, securing member, electrical insulation pad, bar column temperature sensor and leachate stopple coupon; when controllable temperature earth pillar Leaching Experiments device is in using state, electric heater unit is fixedly mounted with in cylindrical heat transfer case, cylindrical heat transfer case top center shell wall is topmost formed centrally groove in lower recess then cylindrical heat transfer box top, the thermofin be laid in groove floor is fixedly mounted with at groove vallecular cavity foot, thermofin is laid and to be arranged at above it and the electrical insulation pad that is arranged in groove vallecular cavity, cylindrical glass cartridge lower end nozzle to be arranged in groove vallecular cavity and to be fixed with the hard gland bonnet sealing its lower end nozzle, hard gland bonnet is contacted the electrical insulation pad that is arranged at below it and to be packed in groove vallecular cavity by the securing member be arranged in groove vallecular cavity so that keep the cylindrical glass cartridge fastener of upright state to be packed on cylindrical heat transfer case and electrical insulation pad fastener is interposed between hard gland bonnet and thermofin, vertically uniform first row perforation and second row perforation is set firmly respectively in the cylindrical glass cartridge cylinder perisporium relative both sides be positioned at above groove, bar column temperature sensor relative set is above groove and respectively to be solidly installed mutually with cylindrical glass cartridge through the mode of first row perforation through cylindrical glass cartridge cylinder perisporium, leachate stopple coupon also relative set above groove and respectively to be solidly installed mutually with cylindrical glass cartridge through the mode of second row perforation through cylindrical glass cartridge cylinder perisporium, the bar column temperature sensor temp probe that one end has separately stretches in cylindrical glass cartridge cylinder chamber through first row perforation, the leachate stopple coupon mouth of pipe that one end has separately stretches in cylindrical glass cartridge cylinder chamber through second row perforation.
During application the utility model, first the electric heater unit of controllable temperature is opened, debug its temperature, temperature is preset, allow electric heater unit slowly preheating again, when it reaches set temperature, load in cylindrical (heat insulation) glass infuser by being equipped with the soil coming from flame range, make it to form soil column, then on time pick-up slip column temperature sensor senses Temperature numerical and will the leachate infiltrated in soil column be poured in cylindrical glass cartridge, different leachates is taken out again from the leachate stopple coupon that place height is different, study by correlation analysis instrument comprehensively and be removed heavy metal parsing and transport phenomena thereof in leachate.The utility model is mainly used in flame range heavy metal-polluted soil migration research.Due to the thermal effect of coal fire, there is temperature field centered by burning things which may cause a fire disaster in flame range soil environment, and the absorption parsing of heavy metal in soil and extent of migration affect by thermo parameters method, heavy metal space distribution difference in soil in different temperature fields.The utility model, as the analogue experiment installation that can build controllable temperature field, studies the transition process at markers such as different temperature fields Soil Under Conditions heavy metals.The utility model structure is more reasonable, effectively can provide the thermograde environment close to actual conditions to upper part soil column, the temperature background of accurate analog flame range soil, resolves and the accuracy of migration research develops skill guarantee for flame range heavy metal-polluted soil.
