Feeding web in a kind of organic polluted soil thermal desorption repair system, feeding packing auger, MW sensitizer feeder, MW generator, MW reactor, discharging auger, reverse thermal desorption device, discharging conveyor belts, deduster, air blast in absorbent charcoal adsorber, transfer valve, gas detect is equipped, neat gas burner in catalytic combustion system, air-introduced machines etc. all realize automatically controlling by PLC system, and there is real time on-line monitoring function, to the important parameter in process, there is memory storage function, achieve the full range in-service monitoring of processing procedure, automatic control.
The course of work of the present utility model and principle as follows:
First, organic polluted soil is transported to feeding packing auger by feeding web, be fed before auger delivers to MW reactor at organic polluted soil and in organic polluted soil, add MV sensitizer from MW sensitizer feeder, the number of the number of inlet amount, the addition of MW sensitizer regulates according to practical operation situation.The radiation of organic polluted soil MW of process in MW reactor, the homogenising of the size realizing dehydration and particle is stirred in the rotation of rotary kiln.This process is by the temperature in the frequency control MW reactor of control and regulation MW generator, and the temperature in general microwave reactor controls at 100-150 DEG C, regulates rotary kiln velocity of rotation to change the organic polluted soil pretreated time.The pretreated organic polluted soil of MW delivers to through discharging auger the process that thermal desorption system carries out next step, and the moisture content through the pretreated soil of MW can reach within 10%, and particle reaches uniformity coefficient substantially.After the pretreatment of MW reactor, most steam evaporates, and wherein containing part organic pollutant, have anti-microwave leakage device at the offgas outlet of reactor, tail gas, by the effect of air-introduced machine, enters into first order deduster.
Secondly, solid dust through pretreated soil and the removing of first order deduster is delivered in reverse thermal desorption device through discharging auger, heated by neat gas burner, general temperature controls at 450-650 DEG C, controls soil processing time in reverse thermal desorption treating apparatus by the rotating speed of index drum.Processing time controls to adjust according to actual conditions, the soil after process also namely repair after soil transported out by discharging conveyor belts and carry out recycling.The a large amount of flue gases containing solid dust produced after thermal desorption enter second level deduster, also carry out recycling through the isolated solid dust of dedusting.Flue gas after first, second grade of deduster dedusting enters the vertical quench tower of condensation depickling treating apparatus, in condensation deacidifying device, makes flue gas carry out cooling and sour gas is soluble in water except acid purification.Waste water after separation sends into organic waste liquor treatment system, first waste water enters dosing pond and carries out neutralisation treatment in this device, waste water after neutralization is more successively by up-flow biological contact oxidation filter tank, vertical sedimentation basin and downflow type aerating biological tank, remove the pollutant such as COD, ammonia nitrogen, total nitrogen, total phosphorus in waste water, processed waste water is up to standard, again enters depickling condensing unit and recycles.Owing to carrying the water droplet of nominal particle size in flue gas secretly, impact for avoiding running follow-up equipment, then gas-liquid separator is entered, water droplet is separated, the condensed water separated enters condensation depickling treating apparatus and reuses, flue gas after gas-liquid separation sends into pulse bag type dust collector, further the fine dusts of remnants is separated and is reclaimed and carry out recycling.
Finally, flue gas after sack cleaner dedusting sends into absorbent charcoal adsorber, advanced person becomes owner of fixed adsorption bed, and organic exhaust gas is through adsorbent bed will wherein Adsorption of Organic be on adsorbent bed activated carbon fiber adsorbing material, and the waste gas after absorption enters into chimney qualified discharge by air-introduced machine.After main fixed adsorption bed absorption is saturated, is switched to auxiliary fixed adsorption bed immediately, thus makes whole system be in continuous duty.Then desorption process is carried out to the saturated main fixed adsorption bed of absorption, suck by air blast in absorbent charcoal adsorber air to parse high concentration organic exhaust gas through the hot blast that electric heater is heated to 120-150 DEG C, be then sent to catalytic combustion system.After treatment smoke discharge tube road is equipped with gas detection equipment, by PLC control system, realizes the automatic desorption process of automatic switchover between main fixed adsorption bed and auxiliary fixed adsorption bed and saturated adsorption bed with this.Greatly reduce the workload of operating personnel like this, also improve treatment effeciency simultaneously.
The heat exchanger in catalytic combustion system is introduced into through absorbent charcoal adsorber desorption organic high-concentration waste gas out, then combustion chamber is entered, neat gas burner heats high-concentration organic waste gas, make the temperature of combustion chamber generally at 200-450 DEG C, after this organic exhaust gas enters into catalyst bed, action breaks through catalyst becomes carbon dioxide and water, release a large amount of heat simultaneously, gas temperature is raised further, high-temperature tail gas after process transfers heat to the organic exhaust gas entered after absorbent charcoal adsorber desorption by heat exchanger, organic exhaust gas after purification enters into chimney qualified discharge by air-introduced machine.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
