Intelligent online volatile organic compound monitoring system

Technical Field

The utility model belongs to the environmental protection field, in particular to but intelligent on-line monitoring system of real-time supervision volatile organic compounds concentration.

Background

When the volatile organic compounds (also called VOCs) are subjected to adsorption and desorption catalytic combustion treatment, the concentration of the volatile organic compounds needs to be monitored, and in terms of the current monitoring, only a single-point single gas circuit can be detected, and the detection equipment is only a detector. The gas that gets into the detection does not do any processing, this kind of traditional detection method can satisfy certain operation requirement, but also has great defect, can only single-point single gas circuit detection, detection efficiency is low, when a plurality of positions and gas circuit all need to detect, just need be equipped with a plurality of detectors, equipment cost is high and detects with high costs, do not do any processing to detecting gas, moisture in the gas, impurity etc. have very big influence to the detector detection precision, lead to detecting the precision low, detection effect is poor, can also influence the life of detector, further increase equipment and detection cost, it is very inconvenient to operate and use.

The to-be-solved technical problem of the utility model is to provide a can carry out that multiple spot multiple gas circuit detects, detection efficiency is high, gaseous can not produce the influence to the detector and damage, detect that the precision is high, detector long service life, a detector can, equipment and detect with low costs, detection effect is good, operation convenient to use is simple and direct volatile organic compounds intelligence on-line monitoring system.

SUMMERY OF THE UTILITY MODEL

For solving above-mentioned prior art can only single-point single gas circuit detect, detection efficiency is low, gaseous not handling can influence the detector precision and damage equipment, equipment and detect with high costs, detect that the precision is low, detection effect is poor, equipment life is short, the operation uses inconvenient scheduling problem, the utility model discloses a following technical scheme:

the utility model provides an intelligent online monitoring system for volatile organic compounds, which comprises an air inlet sampling port, an air inlet sampling filter, an air inlet sampling flowmeter, an air inlet sampling solenoid valve, an exhaust sampling port, an exhaust sampling filter, an exhaust sampling flowmeter, an exhaust sampling solenoid valve, a semiconductor condensation host, an air pump and a volatile organic compound detection sensor with an alarm function, wherein the air inlet sampling port, the air inlet sampling filter, the air inlet sampling flowmeter and the air inlet sampling solenoid valve are communicated with each other through pipelines between two adjacent parts, the exhaust sampling port, the exhaust sampling filter, the exhaust sampling flowmeter and the exhaust sampling solenoid valve are communicated with each other through pipelines between two adjacent parts, the semiconductor condensation host, the air pump and the volatile organic compound detection sensor with the alarm function are communicated with each other through pipelines between two adjacent parts, the exhaust port of the volatile organic compound detection sensor is communicated with the air inlet sampling port through a pipeline.

As right the utility model discloses an improve, still include the reserve solenoid valve of a plurality of, reserve solenoid valve passes through pipeline and semiconductor condensation host computer intercommunication.

The beneficial effects of the utility model reside in that: the gas in different positions and different gas paths is controlled by the solenoid valve to enter, so that multipoint and multi-gas path detection can be realized, the equipment and detection cost is greatly reduced, the influence of gas pre-filtering and dehumidifying treatment on the detection precision and damage of the detector is small, the detection precision is high, the detection effect is good, the service life of the equipment is long, and the operation and the use are convenient and simple.
