Air flow sampling device for pulverizing system and sampling method thereof

Abstract

The invention discloses an air flow sampling device for a pulverizing system. The air flow sampling device comprises a sampling pipeline, an air flow pretreating device and an air flow terminal analysis device, wherein the sampling pipeline is connected with the pulverizing system; one end of the air flow pretreating device is connected with the sampling pipeline, and the other end of the air flow pretreating device is connected with the air flow terminal analysis device; and the sampling pipeline is provided with a heating insulation device. According to the invention, the sampling pipeline is provided with the heating insulation device, so that air flow in the sampling pipeline is prevented from being subjected to dewing phenomena, and dewing does not occur to the interior of the sampling pipeline, therefore, coal powder contained in the air flow can not harden on the surface of the sampling pipeline, thus the smoothness of sampling the air flow at the outlet of the pulverizing system is ensured; and different heating temperatures can be set according to different coal powder moisture contents, and the insulation device is made of an environmentally-friendly material, can achieve heating insulation and dewing-preventing effects and is energy-saving and environmentally-friendly.

Description

technical field [0001] The invention relates to an airflow sampling device and a sampling method for a pulverizing system. Background technique [0002] The existing traditional pulverizing system outlet air sampling device is often blocked and the measurement system cannot work normally. The condensed dusty air is usually hardened around the sampling pipeline, and it cannot be blown through even under the strong air flow of compressed air. This will bring inconvenience to the sampling of the airflow of the pulverizing system and the follow-up monitoring work. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide an airflow sampling device and sampling method for a pulverizing system without dew condensation. [0004] Its technical scheme is as follows. [0005] An airflow sampling device for a pulverizing system, comprising a sampling pipeline, an airflow pretreatment device, and an airflow termi...

Problems solved by technology

[0002] The outlet air sampling device of the existing traditional pulverizing system is often blocked, causing the measurement system to fail to work normally. The condensed dusty air is usually hardened around the sampling pipeline, and it cannot be blown through even under the strong air flow of compressed air.

This will bring inconvenience to the sampling of the airflow of the pulverizing system and the subsequent monitoring work
