High-pressure jet injection system and method for soil remediation agent

Abstract

The invention relates to a high-pressure jet injection system and method for a soil remediation agent, and belongs to the technical field of in-situ soil remediation. The system comprises an agent dispensing system, a pressure supply system and a liquid flow jet system which are communicated in sequence, wherein the agent dispensing system is an agent dispersing station, an agent outlet of the agent dispersing station is fixedly provided with a stainless steel quick coupling, and the stainless steel quick coupling is communicated with an inner chamber of the agent dispensing system; the pressure supply system is a speed-control high-pressure liquid injection pump, a liquid inlet end of the speed-control high-pressure liquid injection pump is communicated with the stainless steel quick coupling through a liquid transport pipeline I, a high-pressure liquid injection pump inlet valve is arranged on the liquid transport pipeline I, a high-pressure liquid injection pipe communicated with the speed-control high-pressure liquid injection pump is arranged at the liquid outlet end of the speed-control high-pressure liquid injection pump, and a high-pressure liquid injection pump outlet valve is arranged on the high-pressure liquid injection pipe; the liquid flow jet system comprises a high-pressure jet pipe and a high-pressure jet nozzle, the high-pressure liquid injection pipe is communicated with the high-pressure jet pipe through a high-pressure water adaptor, and the other end of the high-pressure jet pipe is communicated with the high-pressure jet nozzle.

Description

technical field [0001] The invention relates to a high-pressure jet injection system and method for soil restoration agents, and belongs to the technical field of soil restoration in situ. Background technique [0002] The remediation of contaminated soil usually includes two operation methods: ex situ remediation and in situ remediation. Among them, in-situ restoration does not require excavation and transportation of soil, the construction is simple, the cost is low, and the disturbance to the environment is small, which is an inevitable trend in the development of site treatment technology. [0003] Typical in-situ remediation technologies include in-situ chemical oxidation remediation technology, in-situ gas phase extraction technology, in-situ bioremediation technology, in-situ soil leaching technology, in-situ electromagnetic wave frequency heating technology, in-situ vitrification technology, etc. The in-situ chemical oxidation remediation technology of organic conta...

AI Technical Summary

Problems solved by technology

[0009] However, the application of soil in-situ remediation technology requires equipment to invade the contaminated soil, which will destroy the soil structure to a certain extent, which is time-consuming and labor-intensive, and it is difficult to ensure uniform and effective injection of remediation agents.
