The invention discloses horizontal concentric double-layer
sludge thin-layer
drying equipment, belonging to the technical field of
municipal sewage /
sludge drying. The equipment comprises a left bearing (1), a left bearing cap (2), a left end cover (3), a steam
pipe (4), a support wall (5), an external
evaporation cylinder outer cylinder (6), an external
evaporation cylinder inner cylinder (7), a horizontal scraper blade (8), an inclined scraper blade A (9), a
heat conducting oil
pipe (10), a right end cover (11), a scraper blade arm (12), a rotary wall (13), a right bearing cap (14), a rotating shaft (15), a right bearing (16), an internal
evaporation cylinder support bearing (17), an internal evaporation cylinder outer cylinder (18), an internal evaporation cylinder internal cylinder (19), an inclined scraper blade B (20), a
sludge outlet
pipe (21), a sludge inlet pipe (22), a scraper blade
arm restraint ring (23) and a scraper beam support bearing (24). The horizontal concentric double-layer sludge thin-layer
drying equipment has the advantages of traditional thin-layer drying equipment; in addition, the
axial length of the equipment is shortened, the
layout of a
plant can be improved, sludge with
water content of 85%-70% can be dried into sludge with
water content of 50%-35%.
