Flat-bag dust remover device and fireproofing process thereof

Abstract

The invention discloses a fireproofing process of a flat-bag dust remover in tobacco processing industry and a device. The fireproofing process comprises the following steps of enabling the tobacco to generate sparks in a processing and conveying procedure, when sparks in a dust removing conveying pipeline pass through a spark detector, enabling the spark detector to detect the sparks in 60 microseconds to feed back signals to the controller, performing automatic sound-light alarm, and simultaneously closing a pneumatic butterfly valve so as to prevent the sparks from entering the dust remover to ignite; enabling a controller to instantly send a signal to a high-speed electromagnetic valve arranged on a shower nozzle, opening the electromagnetic valve, enabling the shower nozzle to spray high-pressure water mist, and extinguishing the sparks in a dust removing pipeline. The device comprises the spark detector, the controller, a spraying device, the pneumatic butterfly valve, the dust removing pipeline, the flat-bag dust remover, a dust remover exhaust pipeline, a fan and a silencer. The fireproofing process and the device provided by the invention have the advantages that the security of the flat-bag dust remover is increased, and the safety of the whole system and an operator can be guaranteed.

Description

Technical field [0001] The invention relates to a flat bag dust collector device and its fire prevention technology, in particular to a flat bag dust collector device and its fire prevention technology used in the tobacco processing industry. Background technique [0002] In the tobacco processing process, a large number of broken tobacco stems, broken tobacco dust and smoke will be produced, and the friction between the rotating parts such as the leaf threshing machine, shredder shredder and dryer used in the tobacco processing process will generate sparks. Fires will occur when flammable materials are encountered in the dust removal pipeline, endangering the lives of personnel and the safety of equipment and property. [0003] The existing fire prevention process and device for waste recyclables from tobacco processing use a fire damper. This device is a passive fire prevention device. Sparks in the dust removal pipeline cannot be found. Only after the combustibles are ignited, ...

AI Technical Summary

Problems solved by technology

[0003] The existing fire protection technology and device for tobacco processing waste and recycling use a fire damper, which is a passive fire protection device that cannot detect sparks in the dust removal pipeline. Only after the combustibles are ignited, the fire in the pipeline The fire damper will not close until the temperature reaches the warning temperature value of the fire damper

Such fire protection equipment often cannot play the function of ensuring the safety of personnel and the safety of equipment and property.
