Description
Technical field
The present invention relates to soil remediation processing technology field, relate in particular to a kind of Soil Thermal desorption prosthetic device.
Background technology
China has a large amount of soil to suffer the dirt of the organic pollutions such as benzene,toluene,xylene, ethylbenzene and TPHDye, along with the progressively understanding of the public to organic contamination substance environment and health hazard, exigence economy and havingEfficacious prescriptions method is processed these toxicants. The recovery technique of main organic pollution contaminated soil have biological restoration,Chemistry reparation, physics reparation etc., comparatively speaking, physics reparation or chemistry reparation have applicability widely,Be specially adapted to high concentration, multicomponent organic contamination place. In numerous physics reparations or chemical recovery techniqueIn, thermal desorption is to generally acknowledge the mature and reliable technology of processing organic material contaminated soil.
Thermal desorption recovery technique is through direct heating or indirect, and contaminated soil is heated to enough temperatureDegree, the process that makes its contained organic pollution be volatilized or separate. Thermal desorption is from a phase by pollutantBe converted into the physical separating process of another phase, can by temperature and the residence time of material of controlling thermal desorption systemSelectively to make target contaminant volatilization. Direct heat analyzing device (CN101712042A) adopts directlyMode of heating carries out thermal desorption, but thermal source gas mixes mutually with the dusty gas volatilizing, after having increasedThe processing cost of continuous tail gas, and system energy consumption is high and heat utilization efficiency is low. Therefore how to reduce thermal desorption equipmentOperation energy consumption, energy-saving and emission-reduction are current thermal desorption recovery technique problem demanding prompt solutions.
Summary of the invention
In order to overcome, thermal desorption equipment operation energy consumption of the prior art is large, soil pollution thermal desorption becomes in the present inventionThe deficiency that this is high, provides a kind of Soil Thermal desorption that can reduce energy consumption, greatly reduce Soil Thermal desorption costProsthetic device.
To achieve these goals, the present invention adopts following technical scheme:
A kind of Soil Thermal desorption prosthetic device, comprises support, is located at the cartridge heater of the level on support, described inThe left end upside of cartridge heater is provided with feeding-passage, and the right-hand member downside of cartridge heater is provided with tapping channel, described heatingThe outside of cylinder is provided with solar energy heat collection pipe, and a side of described support is provided with solar energy reflector, described heatingIn cylinder, be provided with main shaft, the surface of described main shaft is provided with hurricane band, and described support is provided with drive shaft and turnsMoving motor, the left end upside of described cartridge heater is provided with air inlet pipe, and the right-hand member upside of described cartridge heater is provided with rowTracheae, described blast pipe is provided with exhaust blower, the inner side of described cartridge heater is provided with rotating cylinder, described rotating cylinder withBetween cartridge heater, form annular gap, between described rotating cylinder inside and main shaft, be provided with some connecting rods.
Contaminated soil through natural drying pretreatment, makes the water content in soil be reduced to symbol before desorptionClose desorption requirement, pretreated soil enters in cartridge heater from feeding-passage, at the work of main shaft, hurricane bandWith under, soil moves to right-hand member from the left end of cartridge heater, solar energy reflector on support is assembled solar irradiationBe mapped on solar energy heat collection pipe, thereby cartridge heater is heated, the heat on cartridge heater passes to rotating cylinder,Rotating cylinder is along with main shaft rotates together, and rotating cylinder is heated evenly, can be equal to the soil at each position in cartridge heater circumferenceEven heating, thus the harmful substance such as benzene,toluene,xylene, ethylbenzene in soil is volatilized from soilForm gaseous state, exhaust blower air draft, drains the toxic gas in cartridge heater, finally arranges from tapping channelHarmful toxic matter in the soil going out significantly reduces, and thermal desorption soil after treatment can be for gardens, plant vegetables etc.,This structure adopts solar energy to heat soil, saves the energy, reduces Soil Thermal desorption cost; When outsideWhen boundary does not have the sun, also can directly pass into high temperature air from air inlet pipe soil is heated, logicalStrong by property.
