Embodiment Construction

[0024] figure 1 The device for detecting the material level in a blast furnace according to the present invention is schematically shown. figure 1 The plug-in laser guns 11, 12 and the plug-in camera gun 21 respectively installed at different positions of the furnace wall W of the blast furnace BF are shown. The laser guns 11 and 12 and the camera gun 21 are usually also introduced with a purge air flow and a cooling water flow to clean and cool them to cope with the harsh environment of the blast furnace.

[0025] The arrangement of cooling water and purge gas of such a plug-in gun body is well known in the art, for example, refer to the applicant's previous related patent applications CN1505387A, CN1877249A, CN206438145U, CN206402324U, CN201540038U, etc., which are incorporated herein by reference. all content.

[0026] The front ends of the laser guns 11 and 12 extend into the furnace and are respectively equipped with emitting optical lens groups 13 and 14. The lasers ar...

Abstract

The invention discloses an industrial furnace detection method and device, and the device comprises a laser gun which carries out the preset conversion of received pulse laser through an optical lens group disposed at the front end of the laser gun, and then emits the pulse laser to a target in a furnace; the pulse laser is used for generating pulse laser supplied to the laser gun; the camera gun is used for receiving and imaging a pulse instantaneous laser pattern reflected by a target in the furnace through a camera mounted at the front end of the camera gun; the synchronous delayer is used for synchronously coordinating the pulse laser and the camera, so that the camera synchronously receives and images a pulse instantaneous laser pattern only reflected by a preset target in the furnace; and the image processing system is used for receiving the image from the camera and analyzing and processing the image to simulate the shape of the target in the furnace. According to the invention, clear charge surface shape images of the in-furnace cloth and the filled furnace charge can be obtained in real time, so that the influence of the environment in the industrial furnace on laser scattering is effectively overcome.

Description

technical field [0001] The present invention relates to the furnace detection technology of industrial kilns, especially blast furnaces. Background technique [0002] Blast furnaces and other industrial kilns are closed reactors, and the kiln environment is mostly high temperature, high pressure, and dusty. The state of charge loading in the kiln is directly related to the production index and normal operation of the kiln. [0003] The closed, high temperature, high pressure and dusty environment inside blast furnaces and industrial kilns has caused great difficulties in the detection and measurement of the charge level. The detection system should not only solve the problem of high temperature and high pressure resistance of parts, but also solve The problem of obtaining a clear image of the material surface without visible light and in the presence of large air flow and dust. SUMMARY OF THE INVENTION [0004] The object of the present invention is to provide a furnace ...
