Active mode surface scanning thermo-detector

Abstract

The present invention is one kind of opto-electromechanical temperature monitoring device, and is one active surface scanning temperature measuring instrument capable of completing the active 2D field temperature field measurement of static target and the performing the video monitoring of the target. The technological scheme includes: setting one light entering opening on the instrument casing for light to enter, setting spectroscope at the opening, setting reflector beside the spectroscope to reflect light to the video camera, setting infrared receiving mirror capable of rotating and oscillating in the inner side of the spectroscope and setting infrared detector to receive infrared and transmit signal the signal processor. The present invention is used in on-line measurement of burning temperature and burning state and is significant in improving work state, raising product quality, saving fuel and reducing harmful gas exhaust.

Description

technical field [0001] The invention relates to a special temperature monitoring device for optical-mechanical-electrical integration, which is mainly used for temperature detection and video recording of the internal temperature field of various industrial combustion kilns. Background technique [0002] During the combustion process of an industrial kiln, since the amount of wind, coal, and material is constantly changing, its combustion surface also changes. In order to achieve optimal combustion, it is necessary to perform temperature detection and flame monitoring on the combustion surface. In the prior art, the technical solution combining "point thermometer" and "industrial TV" is adopted. This solution essentially uses two independent products to independently complete temperature measurement and flame monitoring of combustion conditions. , this technical solution has obvious defects, that is, the temperature at a fixed point represents the dynamic change of the entir...

What is used in the prior art is a technical solution combining "point thermometer" and "industrial TV". This solution essentially uses two independent products to independently complete temperature measurement and flame monitoring of combustion conditions. , this technical solution has obvious defects, that is, the temperature at a fixed point represents the dynamic change of the entire furnace temperature, which is obviously "overgeneralized", and cannot truly reflect the temperature distribution in the entire furnace, and cannot fully understand the temperature in the furnace. Combustion conditions, so it is impossible to remedy the incomplete combustion of the furnace in time, and it is easy to produce NO X , CO harmful gas; due to the failure to accurately understand the dynamic change of the entire furnace temperature, of course it is impossible to accurately control the combustion temperature, it is difficult to meet the process requirements, which in turn affects product quality; insufficient combustion leads to waste of fuel and so on are very common
