Embodiment 1

[0022] Such as figure 1 As shown, the automatic pulverized coal sampling analyzer includes a bracket 11, a sampler, an analysis system 13, a control unit and a weighing device, and the sampler and the analysis system 13 are fixed on the bracket 11 sequentially from top to bottom. Wherein, the sampler is fixed on the top of the support 11, and is used to extract the pulverized coal sample from the pulverized coal pipeline. The output port of the sampler is connected with the input port of the analysis system 13, and the pulverized coal sample collected by the sampler 12 passes through the analysis system. The input port of 13 enters analysis system 13. The analysis system 13 classifies the pulverized coal samples according to different particle sizes, the weighing device is used to weigh the pulverized coal samples of different particle sizes, and the control unit is used to control the operation of the sampler, the analysis system 13 and the weighing device.

Abstract

The invention discloses a full-automatic pulverized coal sampling and analyzing meter. The full-automatic pulverized coal sampling and analyzing meter comprises a sampler, an analyzing system, a control unit and a weighing device and is characterized in that the sampler and the analyzing system are sequentially fixed to the support from top to bottom, and the output port of the sampler is communicated with the input port of the analyzing system; the sampler is used for sampling pulverized coal and inputting the pulverized coal samples into the analyzing system, the analyzing system is used for classifying the pulverized coal samples according to different particle sizes, the weighing device is used for weighing the pulverized coal samples different in particle size, and the control unit is used for controlling operation of the sampler, the analyzing system and the weighing device. The full-automatic pulverized coal sampling and analyzing meter improves accuracy of analysis results, reduces labor intensity of operators, has no adverse effect on operator health and environment and improves working efficiency as the test time is fixed.

Description

technical field [0001] The invention relates to the technical field of coal powder sampling and coal powder fineness measurement, in particular to an automatic coal powder sampling analyzer. Background technique [0002] Boilers generally use pulverized coal suspension for combustion, and the fineness of pulverized coal is an important parameter for boiler combustion adjustment, which directly affects the safety and economy of boiler operation. The finer the pulverized coal, the higher the degree of burnout, the smaller the loss of mechanical and chemical incomplete combustion, the lower the amount of residual carbon in fly ash, and it helps to reduce boiler slagging (commonly known as coking). However, the finer the pulverized coal, the higher the power consumption of the pulverizing system, and the operating cost will increase significantly. Therefore, when the boiler is running, it is necessary to accurately and timely measure and control the fineness of coal powder acco...
