Temperature control is high, and normal temperature-controlled precision is ± 5 DEG C, and temperature-controlled precision can mention ± 3 DEG C, fully meet gypsum calcining and thermal source is wanted
Ask；Biomass-burning can only produce carbon dioxide and flyash, will not produce the pernicious gases such as sulfur dioxide.
4. supported the use using box pulse deduster and cyclone dust collectors and dedusting is carried out to gypsum calcining special furnace, because of stone
Material temperature can take off most of water, therefore Dust Capacity up to more than 150 DEG C, and during material calcining during cream calcining special furnace calcining
Can be especially big, traditional deduster does not fully meet the requirement, and adds two grades of cyclone dust collectors using box pulse deduster
The mode of dedusting can meet requirement, and cyclone dust collectors have treating capacity big, are hardly damaged without any drive disk assembly, and resistance to height
Temperature, can play cooling effect, and box pulse deduster is grease proofing using anti-condensation, and resistance to 170 DEG C, discharge standard is up to 30mg/m3
The dust-removal cloth-bag of specific customization, fully meets state environmental emissioning standard, and a whole set of dedusting can save 30-40% compared with electrostatic precipitator
Energy consumption, and a little repair, high treating effect.
5. ceramic multicyclone dust collector and moisture film device for abatement of smoke and dust two-stage dust removal are used, because hot-blast stove is biomass-burning, so
Carbon dioxide and cigarette ash are primarily present in tail gas, most of cigarette ash is handled using ceramic multicyclone dust collector, removed eventually through moisture film
Dirt device thoroughly removes flue dust, and most CO2 emission, into air, will not pollute air at last.
