Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically to a drilling device for soil thermal desorption remediation. Background Technology

[0002] Drilling equipment for soil thermal desorption remediation is specialized machinery used for in-situ or ex-situ thermal remediation of contaminated sites. It injects a heat source through drilled holes to heat, desorb, and extract contaminants from the soil. Its core functions include precise drilling, integrated heat transfer systems, contaminant collection, and exhaust gas treatment. It possesses high-temperature resistance, precise temperature control, and high-efficiency extraction capabilities, making it suitable for complex geological conditions. It is a key piece of equipment for achieving efficient contamination removal in soil remediation projects.

[0003] In existing soil thermal desorption remediation technologies, traditional drilling equipment often only has a single drilling function and cannot directly heat the soil during the drilling process to promote the volatilization of pollutants, resulting in low thermal desorption remediation efficiency. At the same time, the lack of real-time monitoring of soil parameters and precise temperature control means that overheating or underheating is difficult to avoid, affecting the remediation effect. Moreover, the absence of auxiliary devices to accelerate the diffusion and discharge of volatilized pollutants further limits the improvement of remediation efficiency. Therefore, a drilling equipment for soil thermal desorption remediation that can solve the above problems is needed. Utility Model Content

[0012] Preferably, both the drill rod and the drill bit have internal air extraction channels, and the mounting block has an air outlet on its surface, through which volatile organic compounds can be extracted.

[0013] Preferably, the air extraction channel of the drill bit is equipped with a high-temperature resistant metal filter screen, which can block soil.

[0014] Compared with the prior art, this utility model provides a drilling device for soil thermal desorption remediation, which has the following beneficial effects:

[0015] This drilling equipment for soil thermal desorption remediation features a motor-driven mounting block that rotates the drill rod and drill bit for efficient drilling.
