Tobacco dust flat bag horizontal insertion, off-line deashing and dedusting unit modular combined deduster unit

Abstract

Relating to a tobacco machinery, the invention discloses a tobacco dust flat bag horizontal insertion, off-line deashing and dedusting unit modular combined deduster unit. A plurality of unit vertical partition boards are vertically fixed in a unit box inner cavity and separate the unit box into a plurality of dedusting unit module box bodies that are mutually isolated. Each dedusting unit module is provided with a flat type filter, a gas circuit switch valve group, a pulse-jet system, an ash bucket and an ash discharge valve that are respectively independent. Each dedusting unit module box body is equipped with a to-be-purified air inlet, a purified air outlet, an observation window and a repair door that are respectively independent. When the deduster operates, a working mode that each dedusting unit module undergoes off-line deashing in order is employed, and a flat type filter no longer filters dust-containing gas during deashing, so that the deashing system can be at an ideal state, and the deashing effect is good, the efficiency is high, and the energy consumption is low. The dedusting unit module that does not undergo deashing and dedusting operates continuously, so that the combined deduster unit can be always at an efficient and stable operating state.

Description

technical field [0001] The invention relates to a tobacco machine, in particular to a dust removal unit in which a flat filter bag used for dust collection in the tobacco industry is installed horizontally, the dust removal unit is cleaned off-line, and the dust removal unit is modularized. Background technique [0002] During the production of cigarettes, a large amount of dust will be diffused into the air during the whole process of baking, screening, blending and rolling of tobacco leaves. Dust discharged into the air will directly damage human health. The country has promulgated a series of environmental protection regulations, and the requirements for the control of industrial gas emissions are getting higher and higher. The dust emissions of the tobacco industry must meet the dust content emission standards stipulated by the state before they can be discharged, otherwise dust removal is required. At present, there are two types of flat bag dust collectors used to col...

Problems solved by technology

[0003] The defect of the pulse-jet dust collector is: the cleaning method of the pulse-jet dust collector is that while the same filter bag is cleaning dust, the filter bag is still filtering the air, that is, filtering and cleaning are carried out at the same time, and the air is filtered direction is opposite to that of compressed air

The pressure of the required compressed air is high, the air consumption is large, the filter bag is not easy to clean the dust, resulting in sticky bags, and the dust removal effect is unstable

[0004] The defect of the mechanical rapping dust col
