Embodiment 1

[0043] An integrated dual-fluid injection system for soil and groundwater remediation, especially suitable for in-situ remediation of low-permeability formation pollution in petrochemical sites, which includes injection pump 2, air compressor 3, injection rod 4, injection ejector rod 5, and connecting chamber 6. Injection unit composed of dual-fluid rotary injection head 7 and nozzle housing 8; drug dispensing unit composed of drug configuration tank 9 and drug storage tank 10; electric control cabinet 1, rod box 11, pressing device 12, skid-mounted platform 13 Composed of auxiliary units. All systems are integrated on the skid-mounted platform 13.

[0044] When the dual-fluid injection integrated system is in the injection working state, the injection ejector rod 5, the injection rod 4, the connection chamber 6, and the dual-fluid rotary injection head 7 are connected by threads in sequence. The nozzle housing 8 protects the dual-fluid rotary injection head 7 when it is pres...

Embodiment 2

[0051] An integrated dual-fluid injection system for soil and groundwater remediation, its working process includes:

[0052] Step 1, use a lifting device to lift and place the skid-mounted platform 13 to the repair site.

[0053] Step 2: Move the skid-mounted platform 13 to the injection point so that the pressing device 12 is aligned with the injection point, and lock the self-locking structure on the universal wheel; turn on the power, turn on the mixer in the medicament dispensing tank 9 and start preparing the medicament;

[0054] Step 3, assemble the dual-fluid rotary injection head 7, the connecting chamber 6, the nozzle housing 8, and the injection rod 4 and fix them to the pressing device 12; start the pressing device 12 to start pressing down; when the first injection rod 4 is pressed down , unfix, connect and fix the second injection rod 4 under the pressing device 12, and press down again;

[0055] Step 4, repeat step 3 until the actual depressing depth exceeds th...

Abstract

The invention discloses a double-fluid injection integrated system for soil groundwater remediation. The double-fluid injection integrated system comprises an injection unit, a dispensing unit and an auxiliary unit, wherein the injection unit comprises an injection pump, an air compressor, an injection rod, an injection ejector rod, a connecting cavity, an injection head, a nozzle shell and an injection control mechanism; the dispensing unit comprises a medicine dispensing groove and a medicine storage groove; the auxiliary unit comprises an electric control cabinet, a rod piece box, a pressing device and a skid-mounted platform; and the injection unit, the dispensing unit and the auxiliary unit are all integrated on the skid-mounted platform. According to the integrated system provided by the invention, in-situ injection remediation of soil and groundwater can be completed, double-fluid simultaneous injection of a liquid medicament and gas is achieved, and the dispersion, diffusion and infiltration capacities of the medicament and the mixing capacity of the medicament and underground pollutants are enhanced, so that the remediation efficiency is improved, and the remediation effect is improved.

Description

technical field [0001] The invention relates to an in-situ injection technology system used in the technical field of environmental restoration, in particular to a mobile dual-fluid injection integrated system for repairing soil and groundwater pollution in low-permeability formations. Background technique [0002] my country has long regarded the petrochemical industry as an important pillar industry. The characteristics of petrochemical enterprises such as large water consumption, large displacement, and transportation requirements for raw materials and products have created their layout characteristics near the sea, river, and lake. Among them, there are hundreds of thousands of chemical enterprises along the Yangtze River alone, and the Yangtze River Economic Belt carries 30% of the country's petrochemical industry with 21% of the land. Possible pipeline and storage tank leakage or wastewater discharge in the chemical industry will cause serious pollution to soil and gr...
