Description
Technical field
The design relates to portable raw coal sampling device, belongs to electric power and power engineering technology field.
Background technology
Coal-burning power plant's as-fired coal is sampled as a basic work of boiler controller system performance Index Calculation and diagnosis.Enter stove raw coal sampling and whether will directly have influence on the accuracy of boiler thermal output and unit coal consumption test result accurately and reliably.Duration of test, change on raw coal composition parameter the impact brought in order to reduce the evaporation of raw coal course of conveying Central Plains moisture content of coal, enters generally comparatively near before raw coal enters coal pulverizer and the convenient position sampled of stove raw coal sampling and carries out.Thus, major part test is sampled near feeder.
For the ball type pulverizer system that negative pressure is run, directly can open feeder front end door when entering the sampling of stove raw coal, carry out shovel with sampling shovel and get, convenient and reliable.But for the unit pulverized-coal system of operation under positive pressure, because pulverized coal preparation system run duration feeder is sealing state, cannot sample at front end door.Therefore, enter stove raw coal sampling point and must be arranged in connecting tube between run coal bin to feeder, the coal spout sampling namely above feeder.
At present, the sampling of pressurized direct pulverizing coal system as-fired coal generally has two kinds of modes: (1) installs stopple coupon on coal breakage pipeline, utilizes raw coal to flow automatically and samples, at the raw coal that pipe end place flows out with container collection, as shown in Figure 2; (2) adopt sampling thief to intercept coal sample, as shown in Figure 3, traditional sampler is generally made up of two concentric drums, and the thief hole structure of the two is identical, and interior pipe can circumferentially rotate, and when inner and outer pipes thief hole is overlapping, raw coal enters in pipe, completes a sample period.
But because coal breakage overpressure is comparatively large, be spurting when raw coal flows out, when adopting the first sampling mode, not only raw coal is trickled down outside container and can be caused waste and environmental pollution, and tiny raw coal particle is because of speed, easily impacts testing crew, health risk.When adopting the second sampling mode, the defect of the first sampling mode can be solved preferably, but due to each sampling amount less, sampling flowsheet need be repeated to meet larger raw coal sample demand, which increases the workload of testing crew.
Therefore, design a kind of environmental friendliness, the portable raw coal sampling device of testing crew workload can be reduced again simultaneously, coal is got for coal spout and just seems particularly important.
Summary of the invention
