Description

Detector for detecting granularity diameter and granularity distribution of sintered ore based on vision

Technical Field

The invention relates to the technical field of particle size detection, in particular to a detector for detecting particle size diameter and particle size distribution of sintered ore based on vision.

Background

At present, an atomizing nozzle is widely applied to water-saving irrigation of flower fields, lawns, greenbelts, plants, greenhouses and agriculture, and the atomizing nozzle sprays pressurized fluid into the air through the nozzle, and the sprayed fluid is scattered in a foggy shape. When fluid is atomized by an atomizing nozzle, if the fluid contains particles, the atomizing nozzle can be blocked, so that a laser particle size analyzer is usually required to detect the particle size of the spray, the laser particle size analyzer is an instrument for analyzing the particle size by the spatial distribution of diffraction or scattering light of the particles, and the particle size distribution is tested according to the physical phenomenon that the particles can scatter the laser.

Chinese patent document (CN113188960A) discloses a particle size and particle size distribution detection device, which proposes in the specification that "a large circulating fluidized bed boiler (CFB) of a coal-fired power plant has superior performances of high efficiency, low pollution, adaptability to various fuels, good load regulation performance, strong comprehensive availability of ash and slag, and the like. However, the CFB boiler also puts forward strict requirements on the granularity and the grain composition of the fuel entering the boiler, and the granularity, the grain size distribution and the grain composition of the coal entering the boiler have great influence on ignition starting, operation control and combustion efficiency of the circulating fluidized bed boiler. The basic requirements for the operation of the circulating fluidized bed boiler are that the dilute phase region and the dense phase region are normally distributed when the bed material is boiling, and the bed temperature is kept stable, so the granularity of the coal as fired must be guaranteed, and a proper screening proportion is required. If a large amount of coal blocks enter the fluidized bed to be combusted in operation, the coal blocks can deposit in the bed body to form a dead zone, the normal fluidized state is damaged, the temperature field in the furnace is not uniform, and the furnace is forced to be shut down due to coking caused by over-low bed temperature or over-high bed temperature. If the particle components of the coal are too fine, the amount of fine powder is educed, even the fine powder can not be captured by a separator, the fine powder enters a tail flue after being incompletely combusted, tail fly ash is increased, the carbon content of the fly ash is increased (more than 50% in serious cases), and the thermal efficiency of a boiler is reduced. Therefore, it is very important to sample and detect the granularity and particle size distribution of the coal as fired in time. At present, most circulating fluidized bed power plants detect the granularity and the particle size distribution of coal as fired by adopting a laboratory test method after mechanical sampling or manual sampling; the general test time is 6-8 hours according to different coal types, and the test is carried out once per shift. Therefore, the current methods have the following disadvantages: 1) the real-time detection and timely analysis of the granularity effect of the outlet of the crusher cannot be realized, so that problems can be found and adjustment measures can be taken conveniently; 2) due to the influence of human factors and objective conditions, the detection result has deviation. For a power plant without an intermediate grading coal bunker, the coal after being crushed by the secondary coal crusher directly enters a boiler for combustion through a belt, and because the manual sampling and testing time is long, the coal cannot be detected in time to obtain information feedback, and the coal is sent into a hearth for combustion, is unfavorable for operation regulation, and is not favorable for preventing and controlling the occurrence of boiler operation production accidents caused by excessive granularity in advance. For detecting the granularity and the particle size distribution of coal as fired in a thermal power plant, the current common laboratory test method comprises the following steps: according to a GB/T477-2008 coal screening test method, according to a large screening method and a small screening method, the coal as fired is subjected to granularity grade analysis and inspection according to quality. With the development of new technologies, the following particle size instruments and methods are available: dynamic light scattering method, nanoparticle tracking analysis technology, resonance quality measurement technology, laser diffraction technology, spatial filtering velocimeter, and automatic imaging technology. However, the existing coal as fired detection is in the laboratory detection stage, and cannot realize the online detection of coal as fired ", but in the practical operation application, the problem of the detection effect of the internal lens of the detector cannot be completely solved, so that the following problems still exist in the existing particle size distribution detector and the device described in the cited comparative example:

most current particle size distribution detector adopts the high-pressure draught to handle the impurity on camera lens surface to the mode of camera lens clearance more at the in-process that uses, however in actual use, because whole set of particle size distribution detector adopts the sealed design of integration, lead to placing the condition that the displacement often can appear along with high-pressure gas's circulation in its inside particulate matter that needs to detect, even partial particulate matter can be along with gaseous flow and striking camera lens, not only be difficult to ensure the actual use effect of camera lens, and cause the condition that the fish tail appears on camera lens surface easily, thereby lead to the condition that the detection data very big error appears.
