it is illegal.

It is illegal to produce charcoal in carbonizer, and it will be produced legally if the environmental protection reaches the standard.

1. The raw materials will be unloaded in the factory, and a small amount of dust will be produced after screening dust. The moisture content of this dust is high, up to 51%, and it settles in the workshop, which has little impact on the external environment, so there is no dust removal equipment here.

2. Drying fume The drying fume mainly includes the dust in sawdust, the fume generated in wood combustion and water vapor. The disposal efficiency is 99.9% by using a bag dust collector, and the dust emission rate and concentration can meet the secondary emission requirements of the Comprehensive Emission Criteria for Air Pollutants (GB16297-1996).

3. Rod-making and drying are usually carried out at the same time, and the flue gas is merged into the bag dust collector for drying for disposal.

3. The flue gas of charcoal kiln mainly includes: wood burning flue gas during the ignition of charcoal kiln, white flue gas with high water vapor concentration during heating and drying, carbonization flue gas and wood gas disposal. The national standard should be equipped with a 24-meter-high chimney.
