Description
Technical field
The utility model relates to soil remediation equipment manufacturing technology field, especially contaminated soil repairing test device.
Background technology
After original surrounding city chemical enterprise resettlement, environment and soil are produced to pollution in various degree, thermal desorption recovery technique is one of main restorative procedure of processing at present contaminated soil.Thermal desorption is that direct or indirect heat exchange heating organic contaminants in soil arrives sufficiently high temperature, the process that makes its evaporation and be separated with soil.Its main advantage is not add any chemicals, keeps the original character of soil.But at the scene in actual process, because of the difference of the factors such as different places soil property, moisture content, organic pollution content, realize every also difference of dsc data that adds of the required setting of best repair effect for making plot, in processing procedure, for finding the best repair method in a certain place, usually need to consume mass energy.
Utility model content
The utility model, for the deficiencies in the prior art, proposes a kind of contaminated soil repairing test device, utilizes a small amount of soil and the energy to test and can obtain the required every data of corresponding plot reparation.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme:
Contaminated soil repairing test device, comprises casing, is provided with heating chamber at described bottom half, in described heating chamber one end, air blast is installed, and in described heating chamber, heater is installed,
In described casing above described heating chamber for holding provincialism, in described appearance provincialism, be provided with and the heat conduction airduct of described heating chamber internal communication, on described heat conduction airduct tube wall, have air vent and make that heat conduction airduct is inner to be communicated with described appearance provincialism,
On described top cover of box, be connected with the exhaust column that one end is communicated with described appearance provincialism, the described exhaust column other end is connected with recover, and on described exhaust column, be provided with and take out air blast,
Also comprise electric box, described electric box is connected with described heater and temperature controller, and described temperature controller is connected with the sensor that is arranged on described casing and measures the native cavity temperature of described appearance.
Further, on the described exhaust column of taking out between air blast and described recover, condenser is installed.
Further, on described heat conduction airduct tube wall, air vent has multiplely, is uniformly distributed around described heat conduction airduct.
Further, on described air vent, be buckled with the protective cover that Open Side Down.
Further, the end face of described protective cover is the inclined-plane tilting from inside to outside from top to bottom.
Further, be coated with steel wire outward at described protective cover.
A kind of contaminated soil repairing test of the utility model device, utilizes a small amount of soil and the energy to test and can obtain the required every data of corresponding plot reparation.
Accompanying drawing explanation
Fig. 1 is the structural representation of contaminated soil repairing test device described in the utility model;
Fig. 2 is the schematic diagram of heat conduction airduct described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
Contaminated soil repairing test device as depicted in figs. 1 and 2, comprises casing, is provided with heating chamber 12 in casing 1 bottom, in heating chamber 12 one end, air blast 121 is installed, and heater 122 is installed in heating chamber 12,
Above the interior heating chamber 12 of casing 1, for holding provincialism 11, holding the heat conduction airduct 3 being provided with in provincialism 11 with heating chamber 12 internal communication, on heat conduction airduct 3 tube walls 31, have air vent 311 and make that heat conduction airduct 3 is inner to be communicated with appearance provincialism 11,
On casing 1 top cover 2, be connected with the exhaust column 4 that one end is communicated with appearance provincialism 11, exhaust column 4 other ends are connected with recover 5, and on exhaust column 4, be provided with and take out air blast 41,
Also comprise electric box 6, electric box 6 is connected with heater 122 and temperature controller 7, and temperature controller 7 is connected with the sensor 8 that is arranged on casing 1 mensuration appearance provincialism 11 interior temperature.
On the exhaust column 4 of taking out between air blast 41 and recover 5, condenser 42 is installed, to the organic matter of evaporation is condensed, is convenient to collect.
On heat conduction airduct 3 tube walls 31, air vent 311 has multiplely, is uniformly distributed around heat conduction airduct 3.
On air vent 311, be buckled with the protective cover 32 that Open Side Down; the end face of protective cover 32 is the inclined-plane tilting from inside to outside from top to bottom; and be coated with steel wire 33 in protective cover 32 outsides, steel wire 33 will cover the opening of protective cover 32, avoids soil to enter in pupil while putting soil.
When use, in casing 1, add the contaminated soil (organic matter that contains polycyclic aromatic hydrocarbon) in approximately 40 liter locations to be decontaminated then to open heater 122, add hot-air to sending in soil with air blast 121, the organic matter in soil is evaporated.Add chemical oxidation agent method by retracting device Bian with high one's share of expenses for a joint undertaking sorbing material and accomplish dusty gas zero-emission.So, by add contaminated soil in casing 1, according to the characteristic of this contaminated soil, heat time, heating-up temperature and heating power controlled and selected, the most effectively getting rid of to obtain every data of polluting in soil.
A kind of contaminated soil repairing test of the utility model device, utilizes a small amount of soil and the energy to test and can obtain the required every data of corresponding plot reparation.
