Urban catering oil fume monitoring probe

Abstract

The invention discloses an urban catering oil fume monitoring probe, which includes a lead, a fixed disk, powerful magnets, a monitoring device, an ultrasonic reflection baffle plate and a circuit board. The powerful magnets are all mounted on the fixed disk, the monitoring device is installed on the fixed disk through an aluminum alloy shell, the monitoring device consists of an ultrasonic transducer and sensors, the sensors including a temperature sensor and a pressure sensor that are installed on both sides of the ultrasonic transducer, and the ultrasonic reflection baffle plate is mounted at the top of the aluminum alloy shell through a reflection baffle plate support. The urban catering oil fume monitoring probe provided by the invention has the characteristics of convenient installation and simple structure, only uses one ultrasonic transducer, measures the flow rate by detecting the frequency shift signal and measures the concentration by detecting the sound intensity, has average power consumption of less than 10mW, thus creating the condition for long distance transmission of monitoring signals, and realizing concentration and flow rate monitoring on oil fume in urban catering enterprise oil fume discharge flues and conversion of oil fume discharge amount.

Description

technical field [0001] The invention relates to the field of oil fume monitoring, in particular to an urban catering oil fume monitoring probe. Background technique [0002] Catering industry fume exhaust has become one of the important sources of air pollution in cities, such as PM2.5. The Ministry of Environmental Protection has issued a series of relevant policies for the problem of catering industry fume pollution, and requires the environmental protection bureaus of all provinces, cities, autonomous regions and municipalities directly under the Central Government to And the environmental protection bureaus of key cities for environmental protection have included the problem of oil fume pollution in the scope of normal environmental management work. Strictly prohibit the unorganized emission of oil fume pollution sources, and those without ventilation equipment and purification devices must be forced to install ventilation facilities and purification devices; the emissio...

AI Technical Summary

Problems solved by technology

At present, most of the food and beverage fume concentration monitoring products on the market use semiconductor sensors for monitoring, which have a short life and poor accuracy, and due to the coverage and pollution of oil, the maintenance is very large.
