Chinese soil pollutes and Sustainable Use of Soil Resources and agricultural product ecological safety is constituted a threat to.The farmland that the whole nation is polluted by organic pollution has reached 3,600 ten thousand hectares, and pollutant type comprises petroleum-type, polycyclic aromatic hydrocarbon, agricultural chemicals, organochlorine etc.; The serious oil pollution land area causing because of oilfield exploitation reaches 10,000 hectares, and oil refining industry also makes large area soil be polluted; In Shen, comfort petroleum waste water irrigated area, top layer and subsoil polycyclic aromatic hydrocarbon content, all over 600mg/kg, cause the severe contamination of crops and underground water.The whole nation is subject to heavy metal pollution soil to reach 2,000 ten thousand hectares, and wherein severe contamination soil surpasses 700,000 hectares, and wherein 130,000 hectares of soils are forced to no longer cultivated because cadmium content exceeds standard.Just because of this, the contaminated soil reparation research of China, is just experiencing the transition to the practical stage by laboratory research, is about to enter one fast, comprehensively administer period.
Soil was natural collecting post and the purified treatment place of all kinds of discarded objects originally, soil is received pollutant, do not represent that soil polluted, only have each pollutant of accommodating in soil too much, affect and surpassed the self-purification capacity of soil, thereby in hygiene He on epidemiology, produced injurious effects, just shown that soil has been subject to pollution.Cause the reason of soil pollution a lot, as pollutant sedimentation in industrial sludge, agricultural garbage, sewage irrigation, atmosphere, a large amount of use containing the mineral chemical fertilizer of heavy metal and agricultural chemicals etc.
There is nearly 1/5 pollution being subject in various degree in the existing arable land of China, and contaminated soil will cause crop production reduction, even likely cause that in agricultural product, pollutant exceeds standard, and then be detrimental to health.In addition, along with the acceleration of economic development and urbanization, the contaminated sites that industrial and mining enterprises cause is also very serious.Due to variation and the adjustment of the industrial structure and city layout, the contaminating enterprises such as some chemical industry, metallurgy move one after another, add the bankruptcy of some enterprises, and contaminated site constantly produces.Soil is the important substance basis of human society activity in production, is natural resources indispensable, that be difficult to regeneration.There is no the contaminated site of processing will be Chemical Time Bomb, once large area outburst will cause impact difficult to the appraisal to national sustainable development, therefore must be paid much attention to the prevention of soil pollution and contaminated soil reparation.Therefore be necessary properly management and repaired, it is rationally utilized.
Along with the adjustment of Chinese city planning, city layout, the blowdown enterprises such as many chemical plant, pharmaceutical factory, steel plant move outside, and have left over a large amount of organic contaminations place.Discarded organic contamination place will be developed does commercialization and civilian, and a large amount of toxic organic compound matter wherein, can have a strong impact on ecological environment and health, therefore needs badly organic contamination place is carried out efficiently, repaired fast.The method of physics reparation is having of open report, comprises ablution, evaporation, electric repairing method, hot repairing method, ventilation decontamination and burning method.
Utility model content
The utility model object is to solve the technical problem of the stability, reliability, high efficiency and the energy saving that how to improve contaminated soil original position and showering.Physical method as a kind of repairing polluted soil, thermal desorption technology have technique simple, to pollutant kind and character non-selectivity, equipment is removable, repairing efficiency is short and can effectively prevent the advantages such as secondary pollution, for the contaminated site reparation that in soil, Organic Pollution species is many, toxicity is large, concentration is high, thermal desorption technology is a kind of recommendable improvement technology, and has been used widely.This heater be take chemical industry and be common are organic pollutants as soil remediation object, in repairing according to contaminated soil thermal desorption each influence factor affect rule, mechanism and dynamical mechanism, utility model this thermal desorption soil remediation heater.In order to solve the problems of the technologies described above, the utility model provides comprehensive realization heating, air-supply and the extraction device of a kind of contaminated soil original position and showering, makes soil remediation more efficient.
The technical solution of the utility model is, a kind of heater for soil organic contamination original position and showering, comprise that outer tube 1, heating components and parts support 2, heating components and parts 3, power supply and detection signal source interface 4 and fast thread interface 5 form, outer tube is metal, macromolecule, glass or the ceramic outer tube with permeability, the fast thread interface of a pair of coupling is installed at the two ends of outer tube, and heating components and parts support 2 and heating components and parts 3 are placed in outer tube; Power supply and detection signal source interface 4 are placed in fast thread interface.Further, the fast thread interface 5 of outer tube end is connected outer tube.Become random length.Further, form and the power of heating components and parts are arbitrarily, and have the functions such as acidproof, alkaline-resisting, waterproof.
Further, power supply and detection signal source interface are provided with installing hole at fast thread interface.
Further, the length of outer tube is 500-1500mm, for the area of ventilative hole, is the 0.5-12% of outer tube surface area.
Further, power supply and detection signal interface have the functions such as heat-resisting, acidproof, alkaline-resisting, waterproof.By this interface, can provide power supply to heating components and parts, control temperature; The air pressure of heater present position, flow and polluter content are detected in real time and controlled simultaneously.
The utility model is heating ajutage simultaneously, after by the utility model heater, compressed air being heated via the heating element heater in the utility model heater, sends into soil.
The utility model beneficial effect is, the utility model provides a kind of new thermal desorption device, have that technique is simple, treatment effeciency is high, to pollutant kind and character non-selectivity, equipment is removable, repairing efficiency is short and can effectively prevent the advantages such as secondary pollution, for the contaminated site reparation that in soil, Organic Pollution species is many, toxicity is large, concentration is high, thermal desorption technology is a kind of recommendable improvement technology, and has been used widely.The heater the utility model proposes be take chemical industry and be common are organic pollutants as soil remediation object, in repairing according to contaminated soil thermal desorption each influence factor affect rule, mechanism and dynamical mechanism, this thermal desorption soil remediation heater has Practical significance widely.
