Dust explosion risk pre-control system and an evaluation and early warning method in the grain storage and transportation process

Abstract

The invention relates to the field of dust explosion control of grain storage and transportation, and particularly relates to a dust explosion risk pre-control system and an evaluation and early warning method in the grain storage and transportation process. The system comprises a data acquisition device, a remote control center, an Internet of Things cloud platform and a risk control unit; the data acquisition device is in communication connection with the remote control center; the data acquisition device is used for sending monitoring data of the field environment to the remote control center; the remote control center is in wireless connection with the Internet of Things cloud platform, sends the received data of the data acquisition device to the Internet of Things cloud platform, receives a risk assessment result and drives the risk control unit to act according to the result, and the Internet of Things cloud platform comprises a risk database and a risk prediction assessment module; the system is complete, the monitoring evaluation method is simple, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of dust explosion control for grain storage and transportation, in particular to a dust explosion risk pre-control system and evaluation and early warning method for grain storage and transportation. Background technique [0002] Grain dust is associated with the process of grain storage and transportation. It is inevitable that a large amount of mixed dust will be generated during the process of grain entering and leaving the warehouse, turning the grain surface, lifting, and digging. Especially in the confined space, the higher the grain dust concentration, the higher the safety hazard relatively larger. [0003] The results of the investigation and analysis of the causes of many grain dust explosion accidents at home and abroad show that most of the grain and oil production companies involved do not have enough understanding of the dangers of dust explosions, managers, technicians and operators lack awareness of du...

[0003] The results of the investigation and analysis of the causes of many grain dust explosion accidents at home and abroad show that most of the grain and oil production companies involved do not have enough understanding of the dangers of dust explosions, managers, technicians and operators lack awareness of dust explosion protection, and supervision is not strong enough

Abnormal operation of equipment, local overheating is easy to generate electric sparks, lack of shaft temperature detection device for high-power transmission equipment; lack of real-time detection of dust concentration in key process sections; dust removal process, the actual effect of dust removal has no specific real-time value corresponding to it , operators can only monitor whether the dust removal equipment is in normal operation, and it is difficult to intuitively understand the performance of the dust remover and the effect of dust removal; the dust explosion hazard information files of grain and oil production enterprises are not well established, and the safety information of the production process is lacking, which makes it impossible to monitor the grain. Prediction and control of dust explosion risks
