Description

Technical Field

[0001] The present invention relates to the field of soil remediation control technology, and in particular to an intelligent in-situ chemical oxidation temperature control and safety protection integrated system. Background Art

[0002] Soil in-situ chemical oxidation and reduction remediation technology, specifically, injects oxidants or reductants into the contaminated area of ​​soil or groundwater, and converts pollutants in soil or groundwater into non-toxic or relatively less toxic substances through oxidation or reduction. Common oxidants include permanganate, hydrogen peroxide, Fenton's reagent, persulfate and ozone. Common reductants include hydrogen sulfide, sodium dithionite, sodium bisulfite, ferrous sulfate, calcium polysulfide, divalent iron, zero-valent iron, etc.; suitable for contaminated soil and groundwater. Among them, chemical oxidation can treat most organic matter such as petroleum hydrocarbons, BTEX (benzene, toluene, ethylbenzene, xylene), phenols, MTBE (methyl tert-butyl ether), chlorinated organic solvents, polycyclic aromatic hydrocarbons, pesticides, etc.; chemical reduction can treat heavy metals (such as hexavalent chromium) and chlorinated organic matter, etc. It is greatly affected by humic acid content, reducing metal content, soil permeability, and pH changes.

[0003] However, during the in situ chemical oxidation remediation process of soil, the existing technology is not comprehensive enough in detecting the temperature and pressure inside the soil, which may cause the local temperature inside the soil to be too high and make the remediation agent ineffective. Inadequate monitoring of the internal pressure of the soil may cause excessive pressure and cause accidental explosions. The existing technology also lacks measures to deal with possible accidental explosions and needs further improvement. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent in-situ chemical oxidation temperature control and safety protection integrated system, which can perform more accurate temperature monitoring of the in-situ chemical oxidation remediation process of soil over a wide area and can prevent and deal with high-pressure explosion accidents.

[0084] In the actual application process of the present invention, multiple monitoring shafts are drilled in the soil in-situ chemical oxidation remediation area, and the monitoring well support pipe 11 of the present invention is fixedly placed in the drilled monitoring shafts;

[0085] The rigid chain push rod mechanism 21 is used to drive the temperature monitor 22 to extend out of the monitor extension hole 111, so that the temperature monitor 22 is inserted into the soil along the radial extension of the monitoring well support pipe 11. During the in-situ chemical oxidation remediation process of the soil, the temperature inside the soil is monitored so as to adjust the injection strategy of the remediation agent;

[0086] Part of the temperature sensors 223 in the sensor receiving hole 222 are replaced with pressure sensors, so that the pressure inside the soil can be monitored during the in-situ chemical oxidation remediation process of the soil to avoid explosion accidents caused by excessive pressure;

[0087] The monitor's extended hole 111 is sealed by the extended hole sealing mechanism 14, and the servo motor drives the sealing mechanism support slider 142 to move along the sealing mechanism support slide rail 141, and the sealing mechanism support slider 142 drives the extended hole sealing plate 143 to move together, so that the extended hole sealing plate 143 is sealed and matched with the monitor's extended hole 111, or the extended hole sealing plate 143 is moved away from the monitor's extended hole 111 so that the two sides of the monitor's extended hole 111 are connected;

After the self-propelled driving wheel 44 is supported on the ground, the lifting fixed support cylinder 451 moves upward relative to the ground, driving the explosion-proof ring shell 41 to move upward and away from the ground, so that each self-propelled driving wheel 44 cooperates to drive the explosion-proof ring shell 41 to move as a whole;

[0093] A servo motor is provided in the steering support ring 454, and the servo motor drives the steering support plate 455 to rotate around the axis of the steering support ring 454 through a worm gear transmission structure, thereby changing the travel direction of the self-propelled driving wheel 44;

[0094] A plurality of explosion-proof ring shell segments 410 form an annular explosion-proof ring shell 41, wherein adjacent explosion-proof ring shell segments 410 are in a free separation state. If there is a large obstacle placed on the ground at the pressure abnormality point that cannot be directly crossed, the explosion-proof ring shell segments 410 can be driven away from each other from the free separation position, so that the obstacle bypasses the gap of the explosion-proof ring shell 41, and the explosion-proof ring shell segments 410 at the free separation position are brought closer to each other, and the migration of the explosion-proof ring shell 41 can be completed;

[0095] When an accidental explosion is inevitable, the explosion-proof ring shell 41 and the explosion-proof top cover 42 are integrally covered at the point of abnormal pressure. The impact energy generated by the explosion will be released from each explosion-proof pressure relief pipe 43, and the debris generated by the explosion will be blocked and absorbed by each buffer absorption layer 463 in the explosion-proof buffer mechanism 46. Part of the explosion debris passes through the explosion-proof pressure relief pipe 43 and is intercepted by the debris buffer net bag 433. Afterwards, only the damaged buffer absorption layer 463 needs to be replaced.
