Problems solved by technology

VOCs are extremely volatile and lost. Therefore, although laboratory instrument analysis can accurately identify and quantify VOCs, the samples have to go through multiple intermediate links such as transportation and storage, which greatly increases the possibility of sample volatilization, and the analysis results are not timely. Sexuality, high cost, need to develop on-site VOCs real-time rapid analysis device

Embodiment 1

[0028] Such as Figure 1-2 As shown, the present embodiment provides: a soil VOCs environmental protection detection device, VOCs collection equipment 1 and VOCs measurement equipment 2, the VOCs collection equipment 1 includes a drill bit 3, a casing 4, a push rod 5 and a motor 6; The drill bit 3 is used to drill into the soil at a set depth, and a heating element 7 for heating the soil is arranged therein. The propulsion rod 5 is connected to the drill bit 3 and driven by a motor 6, and is used to drive the drill bit 3 to drill into the soil; The sleeve 4 is arranged on the outside of the propulsion rod 5, in which an air flow channel for volatilized VOCs is formed. One end of the propulsion rod 5 is provided with a placement groove 8, and the heating element 7 is arranged in the placement groove 8. The There is also a thermal conduction column 9 extending downwards on the placement groove 8, and the thermal conduction column 9 is connected to the drill bit 3. The VOCs measu...

Abstract

The invention relates to a soil VOCs environmental protection detection device which comprises a VOCs collecting device and a VOCs measuring device. The VOCs collecting device comprises a drill bit, acasing, a propeller and a motor. The VOCs measuring device is a gas chromatograph, receives volatilized VOCs collected by the VOCs collecting device, and measures the content of various volatile organic compounds therein. Volatilized VOCs can be derived without carrier gas or an air suction device. The detection accuracy of VOCs can be improved. When a heating element in the environmental protection detection device has a fault, the device can operate again by extracting a push rod and then replacing a corresponding heating element. A heat-conducting column is provided with a protective casing, which prevents the heat-conducting column from being broken when the push rod moves.

Description

technical field [0001] The invention relates to an environmental protection detection technology, in particular to a soil VOCs environmental protection detection device for volatile organic compounds (VOCs) in soil. Background technique [0002] Pollutants in the land include not only heavy metals such as mercury, chromium, lead, cadmium, arsenic, nickel, but also organic substances such as benzene series, chlorinated hydrocarbons, petroleum hydrocarbons, polycyclic aromatic hydrocarbons, pesticides, polychlorinated biphenyls, and Inorganic substances such as cyanide and corrosive ions. The raw materials, intermediate products, catalysts or final products in the production process may pollute the land. Affected by long-term industrial activities, land pollution is mostly characterized by combined organic and inorganic pollution. [0003] Common volatile organic pollutants that are harmful to human health include volatile halogenated hydrocarbons, benzene series, and chlori...
