Automatic smoke dust concentration monitoring device

Abstract

The invention discloses an automatic smoke concentration monitoring device and relates to the technical field of smoke concentration monitoring devices. The automatic smoke concentration monitoring device comprises a smoke sampling pipe, a first temperature and humidity control unit, a sampling pump, a smoke concentration detection mechanism and a control system. The smoke concentration detection mechanism comprises a beta-ray detection unit, a filter film inductance detection unit and a filter film replacement unit, wherein the filter film replacement unit is used in cooperation with the beta-ray detection unit and the filter film inductance detection unit, the first temperature and humidity control unit is used for controlling the temperature and humidity in the smoke sampling pipe, and the sampling pump conveys smoke with the temperature and humidity meeting the standard to the smoke concentration detection mechanism; the control system is configured to control the first temperature and humidity control unit, the sampling pump and the smoke concentration detection mechanism and transmit a smoke concentration detection result to a smoke concentration monitoring center in real time through a wireless transmission module. The invention provides an automatic smoke dust concentration monitoring device. The device can realize automatic monitoring of smoke dust concentration.

Description

technical field [0001] The invention relates to the technical field of smoke and dust concentration monitoring devices, in particular to an automatic smoke and dust concentration monitoring device. Background technique [0002] Generally speaking, the method of dust monitoring can be divided into gravimetric method and non-gravimetric (equivalent) method. Non-gravimetric (equivalent) method. There are many methods such as ray method, optical method and electrostatic method. [0003] Most of the non-gravimetric (equivalent) methods have the characteristics of simple structure and meet the requirements of continuous monitoring, but all non-gravimetric (equivalent) methods have the characteristics of poor traceability, and it is difficult to meet the requirements of supervision / regulatory monitoring. [0004] The filter membrane weighing method is a national standard analysis method, which is suitable for meeting supervision / regulatory monitoring. However, at present, the fi...

Problems solved by technology

However, the industrial control of smoke and dust is uneven, and some of them have relatively high humidity, so the error of the final measurement result is also relatively large.

[0006] With the implementation of ultra-low emissions, the demand for accurate on-line supervision / regulatory monitoring of soot concentration is increasingly urgent. Some patent documents that can provide online monitoring of soot concentration have been disclosed in the prior art, but most of them have low measurement accuracy and practicality. Low, in actual use, it is impossible to realize the automatic replacement of the dust filter membrane, the operation is cumbersome, and it is difficult to promote the use of large areas
