Automatic monitoring system for vocs

Abstract

The invention discloses an automatic monitoring system for volatile organic compounds (vocs). The system comprises a housing; an opening-closing door is hinged to the front side wall of the housing; an alarm device and an antenna are fixedly mounted on the upper side wall of the housing; a display screen is fixedly mounted on the front side wall of the opening-closing door; a PID principle vocs detector, an air pump, a secondary filter, a flow meter, a pretreatment device, a zero setting calibration device and a water-air separator are fixedly installed in an inner cavity of the housing. Withthe sensor having high precision, the temperature, the humidity and the vocs can be stably detected; with the pretreatment device, gas to be detected is dried and filtered; the gas detection becomes accurate and usage becomes stable, and the service life of the sensor is prolonged effectively; and with a GPRS wireless module, , data transmission is facilitated; and an alarm device is arranged, andwhen vocs in the gas are detected too high, the alarm devices gives an alarm.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a vocs automatic monitoring system. Background technique [0002] In my country, VOCs (volatile organic compounds) 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 that can volatilize at normal temperature and pressure. or liquid. When the concentration of volatile organic compounds in the indoor air is too high, it is easy to cause acute poisoning. In mild cases, headache, dizziness, cough, nausea, vomiting, or drunkenness will occur; in severe cases, liver poisoning or even coma will occur soon. It may also be life-threatening. [0003] Long-term living indoors polluted by volatile organic compounds can cause chronic poisoning, damage the liver and nervous system, cause general weakness, drowsiness, and itchy skin. Some may also cause endocr...

Problems solved by technology

Some may also cause endocrine disorders and affect sexual function; benzene and xylene can also damage the system and even cause leukemia. There is no device for detecting gases containing volatile organic compounds. Even if there is a device for detecting gases, it can detect volatile organic compounds The effect is not ideal, and there are large errors in the detection results. Therefore, we propose a vocs automatic monitoring system
