BEET PULP DRYING PLANT Russian patent published in 2003 - IPC

FIELD: sugar plants. SUBSTANCE: proposed drying plant includes high-temperature and low-temperature driers, heat-transfer agent supply and discharge branch pipes, waste heattransfer agent discharge pipe line of high- temperature drier including line discharging waste heat-transfer agent into atmosphere with heat exchanger utilizer provided with atmospheric air supply and discharge branch pipes; last branch pipe is connected to heat-transfer branch pipe of low-temperature drier; waste heat-transfer agent discharge pipe line is connected to atmospheric air supply branch pipe. Novelty of invention consists in form of heat exchanger-utilizer consisting of two sections; second section is provided with branch pipes for supply and discharge of return steam condensate, branch pipes for supply of waste heat-transfer agent of high-temperature drier and branch pipe for discharge of condensate of waste heat-transfer agent of high-temperature drier; first section is provided with branch pipe for supply of waste heat-transfer agent condensate of high-temperature drier connected to waste heattransfer agent condensate discharge branch pipe of high-temperature drier of second section and branch pipe discharging waste heat-transfer agent condensate into atmosphere; pipe line discharging waste heattransfer agent of high-temperature drier is additionally provided with circulating pipe line for circulation of part of waste heat-transfer agent of high- temperature drier with heat exchanger provided with return steam supply branch pipe and return steam condensate discharge branch pipe connected to branch pipe supplying return steam condensate of heat exchanger-utilizer of high-temperature drier. EFFECT: intensification of drying process; reduced power requirements; reduced losses; improved quality. 1 dwg
