Description
DESCRIPTION 0503285
COMBUSTIBLE DUST CONTROL DEVICE FOR GRAIN PROCESSING PLANT
The present invention relates to a technical field of grain dust control, in particular to a combustible dust control device for grain processing plant.
Grain processing refers to business activities of converting raw grain into semi-finished grain, finished grain, or converting semi-finished grain into finished grain through processing.
Combustible dust refers to dust that may burn or smolder after mixing with air; the combustible dust suspended in the air will occur an explosion when it reaches the lower limit of the explosion and encountering ignition source burn instantly. Since most of the grain is grain crop, which is a highly combustible substance in a relatively dry space. during the processing, more dust will be generated due to crushing, grinding, peeling and other processes, and a large amount of combustible dust will inevitably be produced; therefore, how to deal with the large amount of combustible dust generated in the production process is particularly important.
At present, most grain processing plants use bag filter to control and absorb dust, the bag filter is a dry dust filter device suitable for capturing fine, dry, non-fibrous dust. Filter bag is made of woven filter cloth or non-woven felt, and uses filtering effect of fiber fabric to filter dust-laden gas; when the the gas containing the dust enters the bag filter, the dust with large particles and heavy proportion settles down dur to effect of gravity and falls into the ash hopper, and the dust is blocked so that the gas is purified when the gas containing finer dust passes through filter material.
In the existing combustible dust control device for grain processing plant, when the dust on a surface of a cloth bag is cleaned, falling dust is scattered in the body, and it takes a period of self- settling before it can completely fall into a collection box, resulting in the cleaning process the body cannot operate normally for a period of time, which greatly reduces the efficiency of the body and is not conducive to the use of the device; for this reason, we propose a combustible dust control device for grain processing plant.
