Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention is not limited to the content described.

[0027] It is used for online identification of dust particles, such as: online detection of fly ash particle ignition loss in different areas of the triboelectric separator.

[0028] Such as Figure 1-4 As shown, the inlet of the pipeline sampling system is composed of three branch pipelines 18 with small inner diameters connected and running through the electrode plate 19 in the friction electric separator. Three electric ball valves 17 are respectively placed on the three branch pipelines. If you need to select other areas To detect the fly ash particles 20, it is only necessary to control the working states of the three electric ball valves 17. When the fly ash particles 20 pass through the electrode plate 19 at a relatively high speed, they are offset due to ...

Abstract

The invention relates to an intelligent fine particle recognition device and method for friction electric separation. The device mainly comprises a pipeline sampling system, a sampling round table, animage acquisition and recognition system and a sample recovery system, dust particles moving in a multi-stage high-voltage electrode plate in friction electric separation equipment are automaticallyacquired, images are recognized and detected, and the dust particles are automatically recovered to solve the problems that parameters of dust particles moving in an existing friction electric separator are difficultly detected, detection period is long, and the dust particles are difficultly recycled after detection and the like. The device has the advantages of short detection period, simplicityin operation, easiness in control and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of collection and image recognition of solid dust particles, in particular to a fine particle intelligent identification device and method for triboelectric separation, which is mainly used for the collection, detection and recovery of powder particles in triboelectric separation equipment . Background technique [0002] Triboelectric separation technology is a relatively common physical separation method, the principle of which is to use the difference in the dielectric properties of different particles. After friction and collision, different particles carry charges with different charges and polarities. When charged particles of different charges pass through the high-voltage electrode plate, they produce different trajectories due to the effects of different electric field forces and gravity. . Separation is carried out by mastering the movement rules of different particles in the triboelectric separat...
