Abstract

The invention provides a full-automatic multifunctional gas detecting and cleaning all-in-one machine, and relates to the field of gas detecting and cleaning. The full-automatic multifunctional gas detecting and cleaning all-in-one machine comprises a PLC, a pressure sensor, a flow sensor, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve, a fourth electromagnetic valve, a fifth electromagnetic valve, a filter, a pressure reducing valve, a first voltage-to-current module and a second voltage-to-current module. The air pump is started through the PLC to sequentially pump air bag samples to the VOC sensor for detection, when numerical values are stable, the instrument automatically collects the numerical values and displays the numerical values on the touch screen, then the nitrogen switch is turned on, nitrogen is used for purging the VOC sensor and the pipeline, then the next sample is pumped to the VOC sensor through the air pump for detection, and the operation is repeated, so that the detection accuracy is improved. The VOC sensor and the pipeline are purged by nitrogen after each time of sample detection is finished, so that the influence of residue or pollution of the previous sample on the next sample is reduced, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of gas detection and cleaning, in particular to a fully automatic multifunctional gas detection and cleaning integrated machine. Background technique [0002] In petrochemical, chemical and gas analysis, a large number of aluminum foil, Tedlar, and rubber bladders are used for sampling. After sampling, they are sent to the laboratory for analysis and determination. The following problems are prone to occur during the use process: 1. New air bags If it is not cleaned before it is put into operation, the residual organic matter, dust and oxygen in the production process of the new air bag will easily affect the normal sample analysis; 2. The one-time use of the air bag is not only expensive to use and dispose of, but also easy to cause environmental pollution; 3. The air bag is easy to cause environmental pollution. Repeated use can easily affect the accuracy of data due to sample residues; 4. Although there a...
