Description
Technical Field
The utility model relates to a waste gas VOC treatment facility especially relates to an install waste gas VOC treatment facility in analysis appearance gas outlet pipeline department.
Background
The on-line gas analyzer is used for analyzing gas composition and belongs to one of flow process analyzers. The gas analyzer is a chemical parameter measuring instrument, and in many industrial production processes, the position of the gas analyzer is comparable to that of physical parameter measuring instruments such as a pressure instrument and a flow instrument, and the gas analyzer can play important roles in controlling production environment, reducing safety accidents and the like. Petrochemical, coal chemical and fine chemical industries need to use on-line analytical instruments, and the instruments can normally work only by virtue of stable outlet exhaust pressure to atmospheric pressure. Such an instrument may be implemented by venting the sample to the atmosphere. However, the discharged sample gas contains a lot of organic gases which pollute the environment, and the VOC exceeds the standard and pollutes the environment. And the current environmental protection requirement is more and more strict, and atmosphere VOC administers the imperative, needs to design a waste gas VOC purification treatment equipment of installing in analysis appearance gas outlet pipeline department.
Disclosure of Invention
The utility model aims at providing an install waste gas VOC purification treatment equipment in appearance gas outlet pipeline department.
The utility model discloses a realize by following technique: the utility model provides an online analysis appearance waste gas VOC treatment facility which characterized in that: the catalyst device comprises a double-layer metal cover cylinder, a catalyst cylinder is arranged between the double-layer metal covers, a net screen cylinder is arranged between the catalyst cylinder and an inner metal cover cylinder, a heating sleeve is arranged in the inner metal cover cylinder, the outer end of the inner metal cover cylinder is connected with a three-way pipe, one interface of the three-way pipe is connected with a VOCs air inlet pipe, and the other interface of the three-way pipe is connected with a temperature controller.
The catalyst cylinder takes micron-sized particle ceramics as a carrier, and a noble metal catalyst is riveted on the carrier.
The noble metal catalyst is a 1-2nm noble metal catalyst.
The heating sleeve is a snake-shaped heating sleeve.
The snake-shaped heating sleeve of the utility model has large actual heating area and longitudinal extension, which can ensure that the catalyst is uniformly heated; the temperature controller controls the heating temperature to ensure that the catalyst is in a working range. The catalyst cylinder is used for low-temperature catalytic combustion of VOCs gases such as benzene series and alkane, the granular ceramic catalyst is densely filled and is tightly contacted with the heating sleeve, and the catalytic conversion of the VOCs gases is complete.
The utility model discloses a sample that catalytic combustion analysis appearance discharged keeps the atmospheric pressure parameter simultaneously, has both guaranteed the normal work of analysis appearance, has prevented VOC polluted environment that exceeds standard again.
