[0002] Traditional power plants are often equipped with multiple units, mainly using anthracite from surrounding areas as fuel. In order to improve the safety and economy of unit operation, reduce unit coal consumption, improve the adaptability of units under new environmental protection situations, and save power generation costs, it is usually necessary to monitor and analyze boiler combustion. As one of the important monitoring and analysis equipment for boiler combustion, the flue gas fly ash carbon content measurement system has particularly important measurement accuracy. Due to the problems of pipeline blockage, severe wear and high maintenance in long-term operation, the equipment cannot be put into operation and measurement normally, resulting in the lack of monitoring boiler combustion operation indicators. Therefore, how to accurately measure the carbon content of boiler combustion fly ash data online in real time and improve the economy of the boiler has become an urgent problem that needs to be solved.
[0003] Therefore, the traditional fly ash sampling device has the problem of uneven distribution of carbon content in the sampled fly ash and unstable measurement data. Utility Model Content

[0015] Figure 1 A structural diagram of a tree-like multi-point distributed fly ash carbon sampling device in one embodiment;
[0016] Figure 2 It is a structural schematic diagram of the cross section of a diamond-shaped sampling pipe in a tree-like multi-point distributed fly ash carbon content sampling device in another embodiment. DETAILED DESCRIPTION
[0017] In order to better understand the present invention, the contents of the present invention are further explained below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.
[0018] In one embodiment, Figure 1 As shown, the utility model provides a tree-like multi-point distributed fly ash carbon content sampling device, which mainly includes: a sampling main pipeline 100 and a plurality of sampling branch pipelines 200; the sampling main pipeline 100 extends vertically into the flue area, and each sampling branch pipeline 200 is distributed in a tree-like manner on the sampling pipeline, and each sampling branch pipeline 200 is within the flue area; a main sampling port 110 is provided on the sampling main pipeline 100, and a branch sampling port 210 is provided at the end of each sampling branch pipeline 200; the sampling main pipeline 100 and each sampling branch pipeline 200 are diamond-shaped pipelines.
[0019] The sampling main pipeline 100 can be placed in the center of the measuring flue, and each sampling branch pipeline 200 can be arranged around the sampling main pipeline 100, that is, the sampling main pipeline 100 and the plurality of sampling branch pipelines 200 are all arranged in the flue area for easy sampling. The sampling main pipeline 100 and each sampling branch pipeline 200 can be made of stainless steel.
[0020] The sampling main pipe 100 may be provided with a main sampling port 110 , wherein the main sampling port 110 may be provided at the middle position of the sampling main pipe 100 for collecting and measuring the carbon content of fly ash samples at the central position of the flue.
[0021] Specifically, each sampling branch pipe 200 can be evenly distributed in a tree-like shape on the sampling pipe to increase the sampling positions and conduct more extensive sampling. Each sampling branch pipe 200 can be provided with a branch sampling port 210 for collecting fly ash carbon samples at various positions in the flue area.
[0022] The sampling main pipeline 100 and each sampling branch pipeline 200 are diamond-shaped pipelines, which can improve wear resistance, reduce scouring surface, reduce equipment maintenance, reduce failure rate, and ensure equipment operation reliability.
[0023] like Figure 1 As shown, four sampling branch pipes 200 can be provided, evenly distributed on the sampling main pipe 100 and in a tree shape. Each sampling branch pipe 200 is provided with a branch sampling port 210, plus the main sampling port 110 provided on the sampling main pipe 100, a total of five sampling ports can be provided.
[0024] In this embodiment, by setting branch sampling ports 210 on each sampling branch pipe 200, the sampling positions can be increased and sampling can be more extensive, making the samples representative and accurately reflecting the fly ash carbon content data in the flue at all times, providing a basis for the operating personnel for the boiler combustion economy.
[0025] In one embodiment, the surfaces of the main sampling pipeline, each sampling branch pipeline, the main sampling port, and each branch sampling port are coated with wear-resistant coating.
[0026] Among them, the wear-resistant coating can be a carbonized wear-resistant coating, which can reduce the wear of the sampling main pipeline, each sampling branch pipeline, and each sampling port caused by flue gas, improve data measurement accuracy, and reduce maintenance.
[0027] In one embodiment, the sampling branch pipes are evenly distributed in the flue area, and the distances between the sampling branch pipes are equal.
[0028] Among them, each sampling branch pipe can be connected to the sampling main pipe by welding, and each sampling branch pipe is distributed in a tree-like manner on the sampling main pipe at a certain distance, so that the main sampling port and each branch sampling port are evenly located in the center of the flue and around it, which can increase the sampling positions and enable more extensive sampling.
[0029] In one embodiment, the diameter of the main sampling pipeline is larger than the diameter of each sampling branch pipeline, wherein the diameters of each sampling branch pipeline may be the same.
[0030] In one embodiment, the size of the main sampling port is the same as the size of each branch sampling port, so that the main sampling port and each branch sampling port can sample evenly. The size of the main sampling port and each branch sampling port is smaller than that of a traditional sampling port.
[0031] In one embodiment, a filter is provided at the main sampling port and each branch sampling port. Since the size of the main sampling port and each branch sampling port is smaller than that of the traditional sampling port and each is provided with a filter, large solid impurities contained in the flue gas can be greatly filtered out, thereby improving the accuracy of data measurement.
[0032] In one embodiment, the filter screen may be a stainless steel filter screen.
[0033] like Figure 2 As shown, in one embodiment, the sampling main pipeline 100 and each sampling branch pipeline 200 are arranged in a diamond-shaped pipeline facing the smoke direction. The diamond-shaped design of the sampling main pipeline 100 and each sampling branch pipeline 200 facing the smoke direction can reduce the smoke scouring surface.
[0034] In one embodiment, the sampling branch pipes are distributed around the sampling pipe in a tree-like shape.
[0035] By setting the sampling ports into five tree-like small sampling ports, in addition to measuring the center of the flue, the carbon content of fly ash around the flue is simultaneously measured, so that the fly ash carbon content samples are collected more accurately; because the size of the sampling port is smaller than that of the traditional sampling port and is equipped with a filter, it can greatly filter out large particles of solid impurities contained in the flue gas; because the various sampling branch pipes are distributed around the sampling pipe in a tree-like shape and are widely distributed, the sampling branch pipes are thinner and are in the center of the flue for a long time, in order to improve the wear resistance of the sampling branch; the pipe is designed in a diamond shape facing the flue gas direction to reduce the flue gas scouring surface, and at the same time, the carbonized dock wear-resistant coating is added to reduce the wear of the sampling tube and the sampling branches contained therein by the flue gas, thereby improving the data measurement accuracy and reducing the maintenance amount.
[0036] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
