Description

VOC pipeline leak hunting device

Technical Field

The utility model relates to a VOC detection area, in particular to VOC pipeline leak hunting device.

Background

Volatile organic compounds in organic waste gas are called VOCs (volatile organic compounds), and in many industries of coating, printing, shoe manufacturing and chemical production, the production process of some industrial products is accompanied by discharge of a large amount of Volatile Organic Compound (VOCs) waste gas. VOCs is the precursor of photochemical reaction, when there is sunshine to shine, VOCs and NOx and other suspended chemical substance take place a series of photochemical reactions under the appropriate condition, mainly produce ozone, form the photochemical smog, thus take place the photochemical pollution; photochemical smog can stimulate eyes and respiratory systems of people, some VOCs also have strong pungent smell, and uncomfortable feeling is generated when certain concentration is reached in the air, so that the air quality is influenced; toxic VOCs (such as aromatic hydrocarbon) gas exists in the environment, which can damage the health of people, and can cause canceration or other serious diseases after being exposed in polluted air for a long time, such as benzene damaging the hematopoietic function of bone marrow, which is a carcinogen; toluene and xylene have a strong anesthetic effect on central nerves; vinyl chloride is a carcinogen. Therefore, the treatment of the VOCs in the organic waste gas is imperative.

The organic waste gas is from various sources, and the generation mode and the emission mode are different. Therefore, the treatment technology of the organic waste gas is also diversified, and various treatment technologies have different advantages and disadvantages. In the actual production process, according to different situations, the selection of a proper method is the key of organic waste gas treatment. The organic waste gas treatment method mainly comprises a recovery method and a removal method. The recovery method mainly comprises the following steps: adsorption, absorption, condensation, membrane separation, pressure swing adsorption, and the like; the elimination method mainly comprises the following steps: physical-chemical methods and biological methods, wherein the physical-chemical methods include thermal destruction methods, photolysis methods, corona methods, ozone decomposition methods, and the like; biological methods include biofilters, biological trickling filters, biological scour towers, membrane bioreactors, activated sludge processes, and the like.

At present, VOC treatment methods are various, but corresponding detection means is lacked for tiny leakage, so that a detection device capable of realizing high-sensitivity detection is urgently needed in the market.
