Non-methane total hydrocarbon on-line monitoring device and monitoring method

Abstract

The non-methane total hydrocarbon online monitoring device comprises a base and a supporting column, the supporting column is installed at the top of the base through bolts, a bearing plate is installed at the bottom end of the supporting column through bolts, and a servo motor is installed at one end of the top of the bearing plate through an installation base; an output shaft of the servo motoris connected with a lead screw through a coupler, the top end of the lead screw is sleeved with a lead screw block, a sliding groove penetrates through the supporting column, a top plate penetrates through the sliding groove, one end of the top plate is welded to one side of the lead screw block, and a detection shell is installed at the bottom of the top plate through a bolt. And a display screenis mounted on one side of the detection shell through a mounting groove and a rubber sealing strip. The non-methane total hydrocarbon online monitoring device and the monitoring method are high in automation degree, simple to operate, rapid and accurate in detection, convenient for remote transmission, convenient for giving an alarm at the first time when numerical harmful components exceed the standard, and remarkable in effect.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to an online monitoring device and a monitoring method for total non-methane hydrocarbons. Background technique [0002] In my country, VOCs are volatile organic compounds, which refer to organic compounds with a saturated vapor pressure greater than 133.32 Pa at normal temperature and a boiling point below 50-260°C at normal pressure, or any organic solid or liquid that can volatilize at normal temperature and pressure. The common ones are benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, TVOC (carbohydrates with 6-16 carbons), ketones and alcohols, etc., while VOSc contains methane non-methane total hydrocarbons and benzene series thing. With the continuous advancement of industrial technology, the pollution of the social environment is becoming more and more serious. The factory will emit a large amount of smoke, and these smoke will contain a large amou...
