VOC online monitor for organic acid environment

Abstract

The invention relates to a VOC online monitor for an organic acid environment. The monitor comprises a monitor body, and a monitoring cavity is formed in the inner side of the monitor body; a cleaningopening is formed in the top of the monitor body; the cleaning opening is communicated with the monitoring cavity; a sealing cover is arranged at the top of the monitor body; the sealing cover is provided with an air inlet hole and an air outlet hole; a vacuum pump is mounted on the upper surface of the sealing cover; an extraction opening of the vacuum pump is communicated with the air outlet hole; an air pressure monitor is installed on the side face of the monitor body, the upper portion of the air inlet hole is communicated with a communicating pipe, one end of the communicating pipe is communicated with an electromagnetic valve, the communicating pipe is communicated with an air outlet of an air inlet non-return mechanism through the electromagnetic valve, and an air inlet of the airinlet non-return mechanism is communicated with an air inlet unit. The movable range of the air inlet unit can be greatly enlarged through a lifting mechanism, so that sampling detection work is conducted on air of different heights.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to an online VOC monitor for organic acid environments. Background technique [0002] VOC stands for Volatile Organic Compounds, which have a huge impact on human health. When the VOC in the room or the environment reaches a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short period of time. In severe cases, convulsions and coma will occur, and it will damage the human liver, kidneys, brain and nerves. VOC outdoors mainly comes from fuel combustion and transportation; indoors mainly comes from combustion products such as coal and natural gas, smoke from smoking, heating and cooking, construction and decoration materials, furniture, household appliances, cleaning Tobacco, textiles, toys, home decoration materials, auto parts materials, electronic appliances and other industries are prone to workshops with high VOC concentrati...

When the VOC in the room or the environment reaches a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short period of time. In severe cases, convulsions and coma will occur, and it will damage the human liver, kidneys, brain and nerves. VOC outdoors mainly comes from fuel combustion and transportation; indoors mainly comes from combustion products such as coal and natural gas, smoke from smoking, heating and cooking, construction and decoration materials, furniture, household appliances, cleaning Tobacco, textiles, toys, home decoration materials, auto parts materials, electronic appliances and other industries are prone to workshops with high VOC concentrations during the production and processing process, which can easily cause discomfort to workers in the workshop Therefore, the environment is detected, and the VOC content in the environment is detected to avoid the impact of excessively high concentrations of VOC on the human body. However, due to certain limitations of the existing VOC monitoring equipment, it is inconvenient for different Sampling and monitoring the VOC content in the air at high altitudes, resulting in poor practicability

Moreover, in an organic acid environment, the relevant monitoring equipment is easily corroded by the organic acid, which not only affects the monitoring effect of the monitoring equipment, but also affects the service life of the equipment. Therefore, the present invention proposes a VOC online Monitor
