Oil fume online detection system and online detection method of oil fume concentration

Abstract

The invention discloses an online oil fume detection system and an online detection method for oil fume concentration. The system includes an oil fume concentration detector installed in an air duct, an anemometer, purification equipment, a single-chip microcomputer, and a communication terminal interactively connected with the single-chip microcomputer. Intelligent monitoring terminal; oil fume concentration detector includes photosensitive oil fume sensor and wet and dry bulb sensor; anemometer includes micro pressure difference sensor, pressure sensor and temperature sensor; purification equipment includes photosensitive oil smoke sensor, dry and wet bulb sensor, UV lamps and photocatalyst layers for sensors and temperature sensors. The invention has a strong catalytic degradation function produced by the photocatalyst layer, which can effectively reduce the interference of ambient light on all sensors, and can degrade and purify all sensors and the oil fumes adsorbed on their probes, which enhances the purification effect and meets the multi-functional requirements of the purification equipment. And the effect of energy saving; and can realize the online real-time detection of oil fume concentration and oil fume exhaust efficiency.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an online detection system for cooking fume and an online detection method for concentration of cooking fume. Background technique [0002] Environmental protection issues have become the focus of attention in the new century and new era, especially the ubiquitous oil fume, which seriously affects health. A large number of studies have shown that various toxic chemical components in oil fume contain carcinogens, carcinogenic initiators and original toxins, which are harmful to the human body. Blood circulation, lung function, and immune function are all extremely harmful, so the monitoring of oil fume emission has become an important issue in protecting the air environment. At the same time, with the increasing shortage of energy, energy-saving home appliances have been paid more and more attention. People have higher and higher requirements for the control function of oi...

AI Technical Summary

Problems solved by technology

[0004] 1) On the issue of monitoring the emission of oil fume in cities, these monitoring technologies are all limited to monitoring the operation status of oil fume purifiers and fans, and cannot achieve online monitoring of oil fume concentration and oil fume exhaust efficiency

[0005] 2) The oil fume purification equipment adopts fixed-frequency manual switch, which cannot meet people's multi-functional and energy-saving requirements for oil fume purification equipment

[0006] 3) The existing oil fume concentration detector is bulky, cannot be installed online, and cannot realize automatic operation and real-time detection

[0007] Therefore, the existing fume intelligent monitoring system cannot meet the needs of the market
