Steam Indirect Heating Industrial Drying Equipment For Drying Sludge
Equipment Introduction
Heating pipes through steam pipe indirect heating dryer provides required heat for drying wet material,
which is one kind of heat conduction type drying equipment, open type and closed type are included. It is
widely applied in chemical, petroleum, light industry, metallurgy, building materials industries, etc. Main
difference between steam pipe indirect heating dryer and normal rotary dryer is that it equips with steam
heating pipes inside of the cylinder, 1-3 circles of pipes are installed in concentric circles inside of the
dryer cylinder, one end is installed above drainage separation chamber of pipes collecting box at the
outlet of the dryer. The other end is installed on tube sheet of the ventilation head with thermal
expansion structure. Seam, hot water and other heat carriers are fed in through steam journal pipe and
distributed to each heating pipe through pipes collecting box. While, condensate water gathers at
header because of dryer slope and then discharge at steam journal pipe. Material is dried by lifting and
mixing of heating pipe and moved from higher side to lower side because of dryer slope. Finally, it
discharges at the end of discharge funnel. Water vapour goes out by induced draft fan or natural
ventilation. If it is organic solvent after vaporization, it can be recycled by seal system. Inert gas can be
used repeatedly.
