Description

Technical Field

[0001] The embodiments of this specification relate to the technical field of boiler treatment, and particularly to a method for treating high-temperature corrosion of boiler water walls. Background Art

[0002] In recent years, environmental protection requirements have become increasingly stringent, and power station boilers are required to fully implement ultra-low emissions, that is, the NOx concentration at the chimney outlet is less than 50 mg / Nm3. In order to reduce NOx, the main combustion zone of power station boilers has to operate in an oxygen-deficient manner, which results in a serious reducing atmosphere and widespread high-temperature corrosion of boiler water walls across the country. The Chinese electric power industry standard DL / T939-2005 stipulates that the wall thickness reduction of the water wall tubes should not exceed 30% of the designed wall thickness. Therefore, the common practice for dealing with high-temperature corrosion of water walls is as follows: during boiler maintenance, first manually clean the coke samples on the surface of the water wall tubes, and then manually measure the wall thickness. For tubes with a corrosion-induced wall thickness reduction exceeding 30%, they are cut and replaced with new water wall tubes after cutting. As a result, the maintenance workload increases, and at the same time, the maintenance cost caused by replacing water wall tubes remains high. Taking a 300MW power plant with severely high-temperature-corroded boilers as an example, the cost of single-boiler single-maintenance tube replacement alone exceeds 2 million yuan. In addition to economic factors, due to the large labor intensity and low efficiency of manual coke cleaning and thickness measurement, and because the boiler shutdown period is often short (the unit tries to generate as much electricity as possible), during the boiler shutdown and maintenance period, there is a rush to complete multiple maintenance operations. Therefore, there is an urgent need to develop a new high-temperature corrosion prevention and control system and method for water walls. Summary of the Invention

Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0020] In this specification, a method for treating high-temperature corrosion of a boiler water wall is provided. This specification is also related to a device for treating high-temperature corrosion of a boiler water wall, a computing device, and a computer-readable storage medium, which will be described in detail one by one in the following embodiments.

[0021] See Figure 1 , Figure 1The figure shows a flowchart of a method for treating high-temperature corrosion of a boiler water-cooled wall according to an embodiment of the present specification, which is applied to a system for treating high-temperature corrosion of a boiler water-cooled wall. The system includes an unmanned aerial vehicle (UAV), a wall-climbing robot, and a control center. The specific steps are as follows.

[0022] Step 101: The UAV obtains scanned image data inside the furnace and transmits the scanned image data to the control center.

[0023] In a possible implementation, the UAV obtains scanned image data inside the furnace, including: the UAV scans the first side wall inside the furnace to determine the first scanned image data; the UAV scans the second side wall inside the furnace to determine the second scanned image data; the UAV scans the front wall inside the furnace to determine the third scanned image data; the UAV scans the rear wall inside the furnace to determine the fourth scanned image data; wherein, the first side wall and the second side wall are opposite, and the front wall and the rear wall are opposite.

[0024] In practical applications, refer to Figure 2 , the system for treating high-temperature corrosion of a boiler water-cooled wall includes a UAV, a wall-climbing robot, and a control center, as well as the power supply, operator, electric welding machine, and cutting machine of the wall-climbing robot. The UAV is equipped with a high-definition camera, which can take photos and videos in real time and transmit the data back to the control center. Among them, the high temperature refers to the temperature range of 200 - 1500 °C. The wall-climbing robot is connected to the power supply through a cable and has two functions: cleaning ash and measuring thickness. The thickness measurement range is 0 - 20 mm. The single-operation range is 2 - 5 water-cooled wall tubes; during the boiler shutdown and maintenance period, first put the UAV into the furnace through the manhole door, scan and record the two side walls, and transmit the scanned data back to the control center.

[0025] Step 102: The control center controls the wall-climbing robot to clean inside the furnace based on the scanned image data and obtains thickness measurement data.

[0026] In a possible implementation, the control center controls the wall-climbing robot to clean inside the furnace based on the scanned image data and obtains thickness measurement data, including: the control center performs modeling based on the scanned image data to determine the furnace cavity model; controls the wall-climbing robot to clean inside the furnace based on the furnace cavity model and obtains thickness measurement data.

[0027] In practical applications, the control center performs modeling according to the scanning results. After the UAV finishes scanning, the wall-climbing robot is used to clean the ash on the water-cooled walls of the two side walls, and at the same time, the wall thickness of the water-cooled wall is measured online.

[0028] In a possible implementation, the wall-climbing robot is controlled based on the furnace chamber model to clean inside the furnace chamber, and thickness measurement data is obtained, including: controlling the wall-climbing robot based on the furnace chamber model to measure the wall thickness of the water-cooled wall in the furnace chamber to determine the initial thickness measurement data; performing ash cleaning operation on the water-cooled wall to determine the ash cleaning result; measuring the wall thickness of the water-cooled wall based on the ash cleaning result to determine the target thickness measurement data.

[0029] In practical applications, when the wall-climbing robot travels on the surface of the water-cooled wall, it can process 2 - 5 water-cooled wall tubes simultaneously. Here, the processing refers to cleaning the tube wall and measuring the wall thickness, and the measurement data is transmitted back to the control center.

[0030] Step 103: The control center determines the thinning amount based on the thickness measurement data.

[0031] In a possible implementation, the control center determines the thinning amount based on the thickness measurement data, including: determining the thinning amount based on the initial thickness measurement data and the target thickness measurement data.

[0032] In practical applications, according to the modeling result after the drone scans, the control center can measure the wall thickness of the cleaned part in real time. Then, the thinning amount can be determined based on the thickness data before cleaning and the thickness data after cleaning.

[0033] Step 104: The water-cooled wall tubes are treated based on the thinning amount.

[0034] In a possible implementation, treating the water-cooled wall tubes based on the thinning amount includes: marking the positions on the water-cooled wall tubes based on the thinning amount to determine the position information; intercepting the water-cooled wall tubes based on the position information to determine the segmented wall tubes; treating the water-cooled wall tubes based on the thinning amount and the designed wall thickness.

[0035] In practical applications, for the water-cooled wall tubes with a wall thinning rate below 30%, no treatment is performed. For the water-cooled wall tubes with a thinning rate exceeding 30%, position marking is carried out. After the wall-climbing robot finishes processing, the control center issues an instruction to the operator, informing the operator of the specific positions of the water-cooled wall tubes with a thinning thickness exceeding 30% of the designed thickness. The operator uses a cutting machine to cut the thinned water-cooled wall tubes according to the marked positions.

[0036] In a possible implementation, treating the water-cooled wall tubes based on the thinning amount and the designed wall thickness includes: in the case where the thinning amount is greater than the first value of the designed wall thickness and less than the second value of the designed wall thickness, performing reverse installation treatment on the water-cooled wall tubes; in the case where the thinning amount is greater than or equal to the second value of the designed wall thickness, replacing the water-cooled wall tubes.

[0037] In practical applications, for the cut water-cooled wall tubes, if the thickness reduction of the tube wall is greater than 30% of the designed wall thickness but less than 40% of the designed wall thickness, after these tubes are installed in reverse (i.e., the thinned side faces the furnace external insulation material side), they are then welded using an electric welding machine, thus saving the cost of tube replacement. If the thickness reduction of the tube wall exceeds 40% of the designed wall thickness, new water-cooled wall tubes need to be replaced.

[0038] In an actual case, for a 350 MW-class coal-fired air-cooled unit in a power plant, the boiler is of the DG1151.1 / 25.4-Ⅱ 4 type, a supercritical parameter variable-pressure operation once-through boiler, with a single furnace, single reheat, front and rear wall opposed firing, balanced draft, tight enclosure, dry bottom, and all-steel suspension structure Π-type boiler. During the overhaul, it was found that at the height of the middle burners, in the 2-meter range at the center of both side walls, there were varying degrees of high-temperature corrosion and thickness reduction of the water-cooled wall in the area up to the height of the overfire air nozzles. The original designed wall thickness of the water-cooled wall tubes was 6.5 mm, and the thickness reduction was about 1 - 2.5 mm.

[0039] In another actual case, the boiler of a power plant is a subcritical, once-through reheat, controlled circulation drum boiler designed and manufactured. The rated evaporation capacity of the boiler under rated conditions is 907 t / h, and the power generation load is 300 MW. The pulverizing system uses steel ball mills, a medium storage type, hot air powder feeding system, single furnace, Π-type, outdoor layout, all-suspended steel structure, and balanced draft. In the main burner area, four layers of primary air nozzles and two layers of tertiary air nozzles are arranged, with tangential firing at the four corners. From the top view of the boiler, the pulverized coal air flow rotates counterclockwise. The main steam parameters are 18.3 MPa and 541 °C. The furnace is 11.97 meters wide (with 180 tubes arranged) and 11.76 meters deep. The water-cooled wall is composed of Ф45*6 mm plain tubes and internally threaded tubes. During the shutdown overhaul, it was found that there were varying degrees of corrosion and thickness reduction of the water-cooled wall tubes on all four walls of the boiler.

[0040] In an overall embodiment, the regions where high-temperature corrosion thinning occurs in a tangentially fired boiler with corner tangential firing and a opposed fired boiler are different. In an opposed fired boiler, corrosion thinning often occurs on the two side walls, while in a tangentially fired boiler with corner tangential firing, corrosion thinning often occurs on the front, rear, and two side walls, that is, it is prone to corrosion thinning in the downstream regions of the four water-cooled wall walls. During the shutdown maintenance period, first put the unmanned aerial vehicle (UAV) into the furnace through the manhole door, sequentially scan and record videos of the four water-cooled wall walls, and transmit the scan data back to the control center. The control center builds a model based on the scan results. After the UAV scanning is completed, then use the wall-climbing robot to clean the four water-cooled wall walls, and at the same time measure the wall thickness of the water-cooled wall online. To speed up, when the wall-climbing robot travels on the surface of the water-cooled wall, it processes 5 water-cooled wall tubes simultaneously. Here, the processing refers to cleaning the tube wall and measuring the tube wall thickness, and the measurement data is transmitted back to the control center. The control center, based on the modeling results after the UAV scanning, does not process the water-cooled wall tubes with a wall thinning rate of less than 30%, and marks the positions of the water-cooled wall tubes with a thinning rate exceeding 30%. After the wall-climbing robot finishes processing, the control center issues an instruction to the operator, informing the operator of the specific positions of the water-cooled wall tubes with a thinning thickness exceeding 30% of the designed thickness. The operator uses a cutting machine to cut the thinned water-cooled wall tubes according to the marked positions. For the cut water-cooled wall tubes, if the wall thinning thickness is greater than 30% of the designed wall thickness but less than 40% of the designed wall thickness, this part of the tubes is installed reversely (that is, the thinned surface faces the furnace external insulation material side), and then welded using an electric welding machine, which saves the tube replacement cost. If the wall thinning thickness exceeds 40% of the designed wall thickness, new water-cooled wall tubes need to be replaced.

[0041] The embodiments of the present specification provide a method and device for treating high-temperature corrosion of boiler water-cooled walls.
