Method for online monitoring the operating state of environmental dedusting system

Abstract

The invention discloses a method for online monitoring the operating state of an environmental dedusting system. The method comprises the steps of: collecting dust concentration data of an environmental dedusting system outlet and each deduster chamber, the vibration signals of a motor and a fan bearing seat, and the pressure and flow parameters of a pipeline system; setting a discharge concentration standard value for the environmental dedusting system outlet and each deduster chamber, and giving an alarm when measured data is larger than the standard value; correcting and determining the actual pressure of a pipeline monitoring point according to relevant parameters of the pipeline system; and obtaining a vibration amplitude component of the motor and the fan respectively from output signals of vibration acceleration sensor, setting a health state factor for the motor and the fan, and giving an alarm when the health state factor is less than zero, wherein the health state factor is calculated from the vibration amplitude component. The method monitors the discharge concentration of the environmental dedusting system, the state of the pipeline system and each deduster chamber, andthe vibration of the motor and the fan in real time, manages the trend, and early warns when a fault occurs to ensure the normal operation of the system and improve the dedusting effect.

Description

technical field [0001] The invention relates to an online monitoring method for the running state of an environmental protection dust removal system. Background technique [0002] The environmental protection dust removal system is widely used in many occasions, including various production sites, especially for the treatment of dust in metallurgical enterprises, it can be cleaned in whole or in part to avoid secondary pollution and noise pollution caused by dust, so as to ensure the cleanest production and living environment. [0003] However, the main problems of the existing environmental protection dust removal system are as follows: [0004] 1) The on-site dust removal equipment is widely distributed, and management and maintenance are inconvenient. It mainly relies on manual inspection, and the accuracy and effectiveness of equipment status control are not high; [0005] 2) Some key parameters still adopt the offline collection mode, which cannot continuously detect ...

AI Technical Summary

Problems solved by technology

[0004] 1) The on-site dust removal equipment is widely distributed, and management and maintenance are inconvenient. It mainly relies on manual inspection, and the accuracy and effectiveness of equipment status control are not high;

[0005] 2) Some key parameters still adopt the offline collection mode, which cannot continuously detect the emission of the dust removal system, and the monitoring data has a certain lag, and cannot guide the maintenance of the dust removal equipment in time;

[0006] 3) The information is scattered, and the monitoring of equipment operation, equipment status and process conditions are independent of each other, and it is impossible to evaluate the influence of process and operation on equipment status; the operation status of equipment is independent of the process parameters of the dust removal system and the environmental emission information of the dust removal system, and cannot to optimize;

[0007] 4) There is a phenomenon that the dust removal system does not match the production and operation parameters and the nature of the dust, resulting in a mismatch in the air volume of the dust removal system, which in turn leads to energy loss or environmental pollution
