Optical correlation type oil smoke detection device with sheath gas protection

Abstract

The invention provides an optical correlation type oil smoke detection device with sheath gas protection. The device consists of a fixing flange plate, a light source generating cavity, a light sourcesignal cavity and a connecting beam, wherein the fixing flange plate, the light source signal cavity and the light source generating cavity are hollow cylinders which are coaxially arranged from leftto right at a circle center in sequence; the fixing flange plate and the light source signal cavity are connected together; a gap is arranged between the light source signal cavity and the light source generating cavity; and the connecting beam is arranged between the light source generating cavity and the light source signal cavity. A sheath air supplementing system is added to the whole device,so that the inaccuracy of data caused by oil smock adhering to a detection lens is avoided, the service life of the equipment is greatly prolonged, and the maintenance frequency of operation and maintenance personnel on the equipment is reduced.

Description

technical field [0001] The invention relates to a device for real-time detection of oil fume by using a light source, in particular to a light-to-beam type oil fume detection device with simple and convenient installation. Background technique [0002] Oil fumes refer to the oils and organic matter volatilized during food cooking and processing, as well as their pyrolysis or pyrolysis products. Excessive discharge will pollute the atmosphere and living environment. [0003] Oil fume monitoring includes oil fume emissions from catering units, design of newly established catering units, environmental impact assessment, completion acceptance of environmental protection facilities and oil fume emissions during operation, food processing units that emit oil fumes, and internal staff canteens of non-commercial units, etc. [0004] For this reason, the country has also issued GB 18483-2001 "Catering Fume Emission Standard". This product is aimed at the real-time monitoring needs o...

AI Technical Summary

Problems solved by technology

[0010] 1. Instability of oil fume concentration: During the actual emission process, the concentration of oil fume is high and sometimes low. The traditional detection method needs to take samples, and then react or test, which will cause data deviation during the collection and detection process;

[0011] 2. The inaccuracy of the detection method: the use of chemicals and other reagents to conduct secondary or multiple detections on the collected oil fumes has already caused data deviations, and multiple multi-point tests are required
