On-line oil smoke detection system and online oil smoke concentration detection method

Abstract

The invention discloses an online oil fume detection system and an on-line oil fume concentration detection method; the system comprises an oil fume concentration detector, an anemograph, purification equipment, a single chip microcomputer and an intelligent monitoring terminal, wherein the oil fume concentration detector, the anemograph, the purification equipment and the single chip microcomputer are arranged in a ventilation pipeline; the intelligent monitoring terminal is in interactive communication connection with the communication end of the single chip microcomputer; the oil fume concentration detector comprises a light sensitive oil fume sensor and a dry and wet ball sensor; the anemograph comprises a micro differential pressure sensor, a pressure sensor and a temperature sensor; and the purification equipment comprises ultraviolet lamps and photocatalyst layers of the light sensitive oil fume sensor, the dry and wet ball sensor, the micro differential pressure sensor, the pressure sensor and the temperature sensor. The online oil fume detection system disclosed by the invention has the functions of strongly catalyzing and degrading through the photocatalyst layers, and therefore, interference of ambient light to all the sensors can be effectively reduced; oil fume adsorbed on all the sensors and probes of all the sensors can be degraded and purified well, and therefore, the purification effect is enhanced, the multifunctional and energy-saving effects of the purification equipment are satisfied, and furthermore, the on-line real-time detection of oil fume concentration and the oil fume exhaust efficiency can be realized.

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

[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
