Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] The purpose of the present invention is to provide a sheath gas protection of the through-shooting oil fume monitoring device, due to the particularity of the oil fume monitoring device must be installed in the oil fume pipeline, long-term contact with oil fume. When a large amount of oily smoke passes through the detection area, it is easy to adhere to the surface of the optical lens, resulting in a discount in data accuracy. Therefore, how to improve t...

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...
