Description
Technical field
The utility model relates to soil and groundwater pollution control fields, especially contaminated site in-situ immobilization field.
Background technique
Currently, the choice of technology of contaminated site soil and groudwater remediation is broadly divided into in-situ immobilization and showering two is big
Classification.Compared with showering technology, based technique for in-situ remediation operates and safeguards fairly simple, and rehabilitation cost is lower, to soil
It disturbs small, is suitble to larger deep subsoil reparation.In-situ remediation method include in situ chemical oxidation technology, in-situ chemical also
Former technology, biology in situ recovery technique, multiphase extraction technique in situ etc..
In situ chemical oxidation technology refers to that will repair medicament by construction injector well injects in contaminated soil or underground water,
Pollutant is converted into the technology for endangering lesser substance.The technology it is relatively easy and operate it is easy to implement, in soil and underground
It is wider that water repairs field application.In-situ chemical reduction technique is similar in situ chemical oxidation technology, mainly will by injector well
Electronation medicament injects in contaminated soil and underground water, and pollutant is reduced to the smaller or nontoxic product of toxicity.It is in situ
Bioremediation technology, the influence substance or collaboration that microorganism growth needs are injected mainly into injector well inject certain bacterium
Liquid promotes increasing for microbe species and quantity in contaminated site, accelerates microorganism and dissolve pollutant.But above-mentioned three kinds
It is related to the technology injected in situ, meeting disturbed strata and filtrate generate mud during medicament or nutrient solution inject, and cause
Injector well silts up, influences medicament and spreads and then influence contaminated site repairing effect.In this case, the side of well-flushing is usually taken
Formula washes out the mud in well outside well.Currently, general pumping and washing process mainly has Beile's pipe well-flushing, air compressor machine well-flushing and diving
Pump well-flushing.Relative to Beile's pipe well-flushing, air compressor machine well-flushing and immersible pump well-flushing are high-efficient, are usually widely adopted.
Patent No. CN 201410763859.8 discloses a kind of ground precipitation deep-well well washing apparatus, which uses pneumatics
Machine blows high-pressure blast to high-pressure air hose as power, and the high-pressure blast in high-pressure air hose is pierced by behind bottom end from well-flushing inside pipe wall and high-pressure blast
It is altered on gap between pipe, meanwhile, shaft bottom silt and water on the outside of well-flushing pipe push well head to by high-pressure blast and rise certain altitude,
Close blowing element air supply tube at this time and stop blowing, the silt particle and water blown afloat in well due to siphonage, can from well-flushing pipe with
It raises at gap between high-pressure air hose, and is sprayed outward from sand removing hole rapidly upward, reached the mesh that shaft bottom silt particle is sucked out
's.But be applied to the device in the well-flushing of contaminated site in-situ immobilization injector well, there are following two deficiencies: first is that should
Distance is larger between device well-flushing pipe and the precipitation deep-well borehole wall, without closed, due in contaminated site in-situ immobilization in injector well
Mud and silt particle may contain pollutant, so the device be applied to injector well well-flushing be likely to result in the secondary of pollutant
Pollution；Second is that, since there are filtrates around injector well shaft bottom, filter cannot preferably be removed by relying only on high-pressure blast in washing well process
Mud in material.
Therefore, in view of the above-mentioned problems, designing that a kind of airtightness is preferable, it effectively prevent the secondary pollution of pollutant, while compared with
The good mud removed in filtrate, the well washing apparatus applied to injector well in contaminated site in-situ immobilization are necessary.
Utility model content
The purpose of this utility model: it is applied to washing for contaminated site in-situ immobilization injector well for precipitation deep-well well washing apparatus
Deficiency present in well, designs that a kind of airtightness is preferable, effectively prevent the secondary pollution of pollutant, preferable to remove in filtrate
Mud, ease of assembly, convenient and efficient, the well washing apparatus applied to injector well in contaminated site in-situ immobilization.
The technical solution of the utility model are as follows: a kind of well washing apparatus applied to injector well in contaminated site in-situ immobilization,
It is characterized in that the well washing apparatus include water butt, well-flushing pipe, clear water well head, compressed air hose, water collector, air compressor machine and
Wastewater barrel, the water butt are connect by well-flushing pipe with clear water well head, and well-flushing pipe one end is connect with water collector, and the other end is logical
It crosses clear water well head to be placed in injector well, the clear water well head is spirally connect with injector well well head, and the compressed air hose is through collecting
Hydrophone is placed in well-flushing pipe, and the water collector is logical by equal tee and variable diameter two and pipe plug is formed by connecting, the air compressor machine
It is placed on ground, the wastewater barrel is connect by well-flushing pipe with water collector.
The utility model has the following beneficial effects: the utility model is applied to injector well in contaminated site in-situ immobilization
Well washing apparatus disturbs the mud in well casing and filtrate using compressed air as power, meanwhile, clear water injects injector well and dilutes well
Interior mud effectively rinses the mud in filtrate, and during well-flushing, the thrust that compressed air is formed is constantly by well-flushing water band
Injector well out realizes that convenient and efficient well-flushing, water collector and clear water well head realize that the airtightness of washing well process, well-flushing water pass through well-flushing
Gap between pipe and compressed air hose is expelled to wastewater barrel along pipeline, and whole process avoids the secondary dirt of well-flushing water
Dye.Water collector 8 and clear water well head 4 realize the airtightness of washing well process, avoid the secondary pollution of well-flushing water, while realizing to phase
Close the intensive assembling of pipe fitting.
In order to adjust the pressure of compressed air, the compressed air hose road is equipped with ball valve control mechanism, passes through ball in this way
The adjustable compressed air pressure of valve control device prevents pressure is excessive from well-flushing water being caused to spray from clear water well head.
