Explosion-proofing infrared UV flame detector

Abstract

The invention discloses an explosion-proofing infrared UV flame detector including an explosion-proofing outer casing, one side of the explosion-proofing outer casing is provided with a shield plate, the inside of the explosion-proofing outer casing is provided with an explosion-proofing inner casing, a first vacuum layer is formed between the explosion-proofing outer casing and the explosion-proofing inner casing, one side, closing to the shield plate, of the explosion-proofing outer casing is provided with a piece of explosion-proofing outer glass, and one side, closing to the explosion-proofing outer glass, of the explosion-proofing inner casing is provided with a piece of explosion-proofing inner glass. The first vacuum layer is formed between the explosion-proofing outer casing and the explosion-proofing inner casing, a second vacuum layer is formed between the explosion-proofing outer glass and the explosion-proofing inner glass, the vacuum layers reduce the effect of heat transfer to make the temperature conduction of the inside and the outside of the sensor slow, thereby preventing internal electronic components from being melted, and reducing the internal blasting probability, and moreover, the detector main body is provided with an infrared flame detector, a UV flame detector, and a high-definition pick-up head, so that the scene of fire can be maximally detected.

Description

technical field

[0001] The invention relates to the technical field of detectors, in particular to an explosion-proof infrared and ultraviolet flame detector. Background technique

[0002] When a substance burns, it produces visible or invisible light radiation while producing smoke and releasing heat. Flame detectors, also known as photosensitive fire detectors, are used to respond to the light characteristics of a fire. That is, a fire detector that diffuses the light intensity of flame burning and the flickering frequency of flame. According to the optical characteristics of the flame, there are two types of flame detectors currently in use: one is an ultraviolet detector that is sensitive to light radiation with a shorter wavelength, and the other is an infrared detector that is sensitive to light radiation with a longer wavelength. The ultraviolet flame detector is a detector that is sensitive to the ultraviolet spectrum emitted by high-intensity flames. It uses a sol...
