Safety monitoring system and method for flour processing

Abstract

The invention discloses a safety monitoring system and method for flour processing. The system comprises a dust concentration collection module, an oxygen concentration collection module, an alarm module, a dust removing module, and a control module. To be specific, the dust concentration collection module is used for collecting the current dust concentration A; the oxygen concentration collection module is used for collecting the current oxygen concentration B; the alarm module connected with the control module is used for carrying out action based on an instruction from the control module to send out warning information; the dust removing module connected to the control module is used for carrying out action based on an instruction from the control module to remove dust; and the control module is in communication connection with the dust concentration collection module and the oxygen concentration collection module. The control module obtains the current dust concentration A by the dust concentration collection module, obtains the current oxygen concentration B by the oxygen concentration collection module, compares the A with a preset dust concentration value and compares the B and a preset oxygen concentration value B0, and controls the alarm module and the dust removing module to carry out processing by integration of two comparison results.

Description

technical field [0001] The invention relates to the technical field of grain processing, in particular to a safety monitoring system and method for flour processing. Background technique [0002] Dust fire and explosion accidents mostly occur in coal mines, flour mills, sugar factories, textile mills, sulfur factories, feed, plastic, metal processing factories and grain depots and other factories and mines. Dust explosion itself is a special kind of combustion phenomenon, and it also needs three conditions: 1. The dust itself is combustible dust, flour, wood powder, chemical fiber dust, etc., are basically combustible; 2. Dust must be suspended in combustion-supporting gas such as In the air, mixed to reach the lowest explosion limit of dust concentration; 3. There are electric sparks, static electricity, friction sparks, open flames, high-temperature object surfaces, welding and cutting sparks. When the above three conditions are met at the same time, dust fire and explosio...
