Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal blending combustion management, and more particularly to a coal bunker dynamic monitoring method and device based on a Euro bunker. BACKGROUND

[0002] At present, for most coal-fired power plants in China, if the designed coal is used for combustion, the coal-fired unit has good adaptability, can ensure safe and economic operation, and meet the environmental protection requirements; but if non-designed coal is used for combustion, it will cause poor boiler combustion effect, and the safe operation of the boiler is difficult to guarantee. In addition, China's coal resources are limited and unevenly distributed. In recent years, the price of coal has risen rapidly, and the transportation pressure has increased. Many coal-fired power stations have difficulty in ensuring the supply of designed coal. In addition, in order to ensure power production and reduce power generation cost, power enterprises must also "multi-point" purchase coal according to market conditions. Therefore, the use of non-designed coal and the blending of multiple coal types in thermal power plants has become an unavoidable situation.

[0003] In December 2020, the coal yard of Huaneng Shanghai Shidongkou No. 1 Power Plant was closed and reconstructed, and the first Euro bunker in China was put into use. Compared with traditional open-air and storage coal yards, the Euro bunker has the advantages of small land occupation, large storage capacity, full enclosure, no dust, anti-spontaneous combustion, and intelligent management system. The land occupation area is only 1 / 6 of that of an open-air coal yard, and the maximum storage capacity of a single bunker is 90,000 tons. Compared with the open-air coal yard of a coal-fired power plant in China, the storage of coal in the Euro bunker not only has little impact on the environment, but also prevents the spread of coal dust everywhere, reduces the contact area between coal and air, reduces coal oxidation, and reduces coal storage loss, which is the most environmentally friendly.

[0004] How to optimize the coal blending combustion method based on the Euro bunker plays an important role in filling the gap of intelligent management of the Euro bunker in China and improving the level of intelligent management, and has great significance for realizing the safe, environmentally friendly and economic operation of the boiler under the condition of coal blending combustion based on the Euro bunker.

[0029] In order to make the objects, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0031] Eurobin is a silo originated from the Netherlands for storing bulk materials. There is no application example in China. In December 2020, the coal yard of China Huaneng Shanghai Shidongkou No. 1 Power Plant was completed for closure reconstruction, and the first Eurobin in China was put into use.

[0032] Before the specific solutions of the present application are described, the feeding and discharging operation mode of the Eurobin will be briefly described. During the feeding and discharging operation of the Eurobin, coal is conveyed by the feeding conveying system to the feeding chute located at the top center of the silo. The feeding chute guides the coal to the telescopic chute. The coal falls through the telescopic chute and lands on the drill frame located near the top of the coal layer in the silo. At the lower end of the telescopic chute, the coal is distributed between the balance auger and the hole digging auger. The balance auger and the hole digging auger spread the coal along the radius of the silo towards the silo wall. The rotary bridge rotates in the clockwise direction. The drill frame suspended on the winch steel cable moves with it. When the coal in a section is spread out, the rotation stops. The auger continues to fill the next section. When the rotation angle of the rotary bridge exceeds 360°, the winch lifts the drill frame by one layer thickness.

[0033] The coal starts to flow out of the silo, and a coal pit will be formed in the silo. At this time, the two (balance and hole digging) augers start to run in the unloading direction. The rotary drive will run in the counterclockwise direction to recover one layer thickness of coal. The coal is conveyed to the center of the silo and fills the coal pit there. During unloading, the rotary bridge continuously moves in the counterclockwise direction, and when it completes a full rotation, the winch lowers the drill frame by one layer thickness. The system will continue to draw the next annular coal layer. This process will continue until the drill frame approaches the bottom of the silo.

[0034] Compared with traditional open-air and storage coal yard, the Euro Bin has the advantages of small land occupation, large storage capacity, full sealing, no dust, anti-spontaneous combustion, equipped with intelligent management system, etc. The land occupation area is only 1 / 6 of the open-air coal yard, and the single bin can store up to 90,000 tons of coal. Compared with the open-air coal yard of the coal-fired power plant in China, the storage of coal in the Euro Bin coal yard not only has little impact on the environment, but also prevents the spread of coal dust everywhere, reduces the contact area between coal and air, reduces the oxidation of coal, reduces the loss of stored coal, and is the most environmentally friendly.

[0035] The following will be described in detail Figures 1-3 The method and device for dynamically monitoring the coal bin based on the Euro Bin provided by the embodiment of the application.

[0036] Figure 1 The flowchart of the method for dynamically monitoring the coal bin based on the Euro Bin provided by the application is shown in Figure 1 The following steps are included but not limited to:

[0037] Step 101: Obtain the feed sample of the annular coal layer at the Euro Bin feed chute, and perform chemical analysis on the feed sample to obtain the initial feed data of the annular coal layer.

[0038] The initial feed data includes coal type data and coal quality time data.

[0039] In one embodiment, when it is detected that the coal level data of an annular coal layer in the Euro Bin has a large change within a certain time, the coal level change rate at the Euro Bin feed chute is calculated based on the coal level data. When the coal level change rate exceeds a predetermined threshold, for example, a change of 0.5 meters within 2 minutes of on-site measurement, it indicates that the Euro Bin starts to feed coal, and the feed sample of the annular coal layer at the Euro Bin feed chute at this time is obtained.

[0040] Alternatively, the coal level data of the Euro Bin is obtained, and the coal level change rate at the Euro Bin feed chute is calculated. When the coal level change rate exceeds a predetermined threshold, the feed sample of the annular coal layer at the Euro Bin feed chute is obtained. For example, an automatic sampler is arranged in the feed conveying system in front of the Euro Bin feed chute. When the coal level change rate exceeds a predetermined threshold, the automatic sampler immediately obtains the feed sample of the annular coal layer at the Euro Bin feed chute at this time, and the samples are uniformly analyzed by day to obtain coal type data and coal quality time period data.

[0041] Step 102: Obtain the Euro Bin feeding and discharging radar real-time data, and calculate the target feed data of the annular coal layer based on the Euro Bin feeding and discharging radar real-time data and the initial feed data.

[0042] The target feed data includes feed coal type data, coal quantity data, coal quality data, and storage location data. The feeding and discharging radar real-time data includes feed flow data and discharge flow data.

[0043] Specifically, according to the coal type data of each annular coal layer, the coal quality time period data and the feeding flow data in the real-time data of the feeding and discharging radars, the feeding flow data is the measuring point data of the feeding flow in the field, and the feeding coal type data, the coal quantity data and the coal quality time data of each annular coal layer of the Euro bin are calculated by a coal quantity detection algorithm.

[0044] The coal level data can be measured by a coal level meter, and a measuring data is transmitted into a DCS (Distributed Control System) every interval of a certain time, and the coal level meter is arranged at a position such as the top or side of the Euro bin. The specific position of the coal level meter can be adjusted and determined according to the actual situation to ensure accurate coal level measurement and monitoring, which is not limited in the present application. Since the Euro bin is layered to take coal, after the discharging coal type data in the real-time data of the discharging radars of each annular coal layer is obtained, the layered data marking is performed, and the feeding coal type data, the coal quantity data, the coal quality data and the storage position data of each annular coal layer of the Euro bin can be further calculated.

[0045] Step 103: based on the target feeding data, a dynamic graph is established to realize dynamic monitoring of each annular coal layer in the Euro bin.

[0046] Specifically, a mapping relationship table of the coal level data and the coal quantity data is established based on the target feeding data; the coal bin discharging quantity of the current annular coal layer is calculated based on the discharging flow data; wherein the current annular coal layer is the coal layer located at the discharging port of the Euro bin.

[0047] At the same time, the use time of the remaining coal quantity in the coal bin and the coal level data of each annular coal layer are calculated based on the target feeding data of each coal layer and the coal bin discharging quantity of the current annular coal layer, and the coal level data of each annular coal layer is used as the coal layer boundary surface to establish a dynamic graph of the coal layer layered interface, so as to realize digital detection of each annular coal layer, wherein the coal quantity, the coal type, the coal quality and the coal level data of the Euro bin are displayed in real time through the form of the dynamic graph to show the layered interface condition in the bin, and an alarm threshold value can be set to remind the fuel operator when the coal type changes, the coal level is too low or too high.

[0048] The calculation principle of the interface is introduced as follows: when it is detected that the coal level corresponding to a certain raw coal bunker (assuming A) has a large change in a certain time (change of 0.5 m within 2 min measured on site), it indicates that the A bunker starts to feed coal, then the coal type data of the uppermost annular coal layer set by the current A bunker is read, and the coal level of the current annular coal layer at this time is also read, which is the starting interface of the two coal layers, and the interface is recorded at the same time, and the corresponding relationship curve of the coal level and the coal quantity is inquired, so that the current residual weight can be calculated, and in the time period of Δt, the consumption of the coal type in the current annular coal layer can be calculated by integrating the coal feeding quantity of the feeder, and then the coal level of the current coal type, i.e. the position of the interface, can be calculated by inquiring the corresponding relationship curve of the coal level and the coal quantity, and when the value of Δt is small enough, the calculated interface can be considered as the real-time interface. In addition, the current coal type and the time that all the stored coal can continue to be used can also be obtained by using the current coal feeding quantity.

[0049] Meanwhile, due to the slight difference in the density of different coal types, and the fluctuation of the coal level during operation, there is a certain error between the measured value and the actual coal level, which may lead to inaccurate tracking of the coal type in the coal bunker. Therefore, the error needs to be corrected. Specifically, a method such as using the thermal balance of the pulverized coal in the coal mill to soft measure the moisture can be used as a verification method.
