Description
Technical Field
The invention belongs to the field of intelligent power plants, and particularly relates to a coal as fired recognition device based on radio frequency recognition and an online coal quality monitoring system.
Background
China thermal power generating units often need to continuously operate under frequent and large changes of coal quality and even coal types. On one hand, the design of the power station boiler is influenced by the reserves and the marketization operation of coal mines, the stable supply of the whole life cycle of a power plant cannot be guaranteed, and on the other hand, because the coal price is marketized but the electricity price is relatively fixed, the thermal power profit is greatly compressed, and the combustion of low-quality coal or mixed coal becomes the inevitable choice of most power plants. The method provides challenges for the combustion optimization of the power station boiler, and actually, combustion optimization strategies aiming at different coal types and multi-coal-type mixed combustion are preliminarily established, but the identification of the coal as fired causes great obstruction to the combustion optimization of the coal-fired power plant. Although the existing coal quality on-line detection can realize minute-level rapid detection, the method cannot be used for real-time operation control to solve the problems of combustion and coordination control caused by coal quality fluctuation, and the main reasons are as follows:
(1) it is difficult to directly measure the quality of coal entering the furnace. On one hand, an online coal quality detection device is expensive, and for a mainstream high-power coal-fired unit provided with 5 to 6 coal mills, the online direct measurement of the coal quality entering the furnace is carried out, one online detection device is required to be configured for each coal mill, and the investment cost is too high; on the other hand, corresponding spaces and configuration schemes are not reserved at the inlet and the outlet of the coal mill designed for the conventional typical power station to arrange sampling and on-line detection equipment, so that the conventional coal quality on-line detection device is arranged on a coal feeding belt, the coal quality detected on line needs to enter excessive conveying belts, coal ploughs, raw material storage and other links, the retention time in a raw coal bunker is usually as long as 6 hours, the coal quality detected on line is far away from the actual coal as fired, the coal quality can not be directly used for on-line actual operation control, and the coal quality can only be referred to by operating personnel within a certain range.
(2) The on-line data of the coal quality of the coal fed into the furnace is used for estimating the coal quality of the coal fed into the furnace, so that the uncertainty is large. Under the premise that the coal quality of the coal entering the furnace is difficult to directly measure, the estimation of the coal quality of the coal entering the furnace by utilizing the coal quality of the coal entering the furnace and the related conveying belt, the coal plough, the material level of the raw coal bin and the like has certain feasibility theoretically, but larger uncertainty exists actually. Particularly, when coal material passes through a raw coal bunker, on one hand, the measurement difficulty of the material level of the raw coal bunker is high, the output of a material level measuring device mainly based on point measurement is often uncertain greatly due to collapse, pile height, vibration and the like of a material level top cross section in the bunker, the precision of the measurement time of the actual coal quality change in the charging process is deviated by a plurality of minutes by the large bunker cross section and exceeds the precision requirement required by real-time operation control, and on the other hand, when coal of coal types enters the same raw coal bunker, the flowing and mixing of the coal types are very complicated, the difference of the flowability of different coal types is large, and the effective prediction is difficult.
In summary, although various types of coal quality online detection devices have been introduced, accurate identification of coal as fired is still a critical issue to be solved in most coal-fired power plants.

The above is a specific structure of the coal quality online monitoring system 1000 provided in this embodiment, and the working process of the coal quality online monitoring system 1000 based on the above structure is as follows:
as shown in fig. 1 to 7, according to the standard coal quality detection result of the coal entering the field, when the bucket wheel machine takes the coal from the coal pile, the corresponding coal quality information is written into the spherical rf tag 11 by using the coal belt bid 100, and the spherical rf tag 11 is placed at the coal belt.
Then, the spherical radio frequency tag 11 enters the coal feeder through the coal conveying belt, the coal plough and the raw coal bunker along with coal materials corresponding to the coal quality.
Next, the as-fired coal identification device 200 identifies the coal quality information recorded by each spherical rf tag 11 entering the coal charge of the coal feeder.
Then, the coal quality determining device in the coal feeder judges the abundance of the corresponding coal in the coal feeder according to the coal quality information in the spherical radio frequency tags 11 identified by the coal identification device 200 in the coal feeder and the quantity and the density of the spherical radio frequency tags 11; and further correcting the coal as fired information by combining the flow and the flow speed of the coal feeder, thereby determining the coal quality of the coal entering the coal fired boiler in real time.
For example, the medium-speed coal mill mainly comprises lean and soft coal, partial lignite with total moisture less than or equal to 19%, and the like, and has the advantages of low initial investment cost, low coal-milling power consumption and stable operation, so that when the coal pulverizing system is selected in large-scale thermal power generation projects at home and abroad at present, the medium-speed coal mill is used as a preferred scheme for matching with the coal mill of the coal pulverizing system. However, the method has poor adaptability to coal types, and is not suitable for coal types with high ash content and large stone-containing coal quantity. Taking an HP863 medium-speed coal mill produced by a Shanghai heavy-duty machine plant adopted by a 350WM subcritical unit of a certain power plant as an example, the maximum output of the medium-speed coal mill reaches 44t/h for certain bituminous coal with ash content of 4.6% under the same condition, and the maximum output of the medium-speed coal mill only reaches 30t/h for certain lignite with ash content of 17.22%. The number ratio of the bituminous coal/lignite labels identified at the coal feeder is increased from 3:7 to 5:5 and stabilized at the same bidding time interval by using the labels of two kinds of coal transported at the same conveyor belt speed, at the moment, the output of the coal feeder is 10t/h, and according to the two kinds of coal fed to a coal as fired database, the remarkable bituminous coal proportion increase of the coal as fired after 5min can be obtained, and the bituminous coal/lignite proportion of the coal as fired tends to be stabilized after 7.5 min.
The above is merely an illustration of the technical solution of the present invention. The coal as fired identification device and the coal quality on-line monitoring system based on radio frequency identification according to the present invention are not limited to the above-described structures, but are subject to the scope defined by the claims. Any modification or supplement or equivalent replacement made by the person skilled in the art on the basis of the present invention is within the scope of the claims of the present invention.
