Title:
FROSTLESS MULTIVARIABLE COUPLED TYPE HEAT PUMP HOT BLAST STOVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/085453
Kind Code:
A1
Abstract:
A frostless multivariable coupled type heat pump hot blast stove system, for use in providing hot air for grain drying. A first heat exchanger (4-2), a second heat exchanger (5-2), and a heat pump unit consisting of a compressor (1-1, 2-1, 3-1), a condenser (1-2, 2-2, 3-2), a throttle device (1-3, 2-3, 3-3), an evaporator (1-4, 2-4, 3-4), and a gas-liquid separator (1-5, 2-5, 3-5) are provided in the system. By means of heat pipeline connection configurations of the first heat exchanger (4-2), the second heat exchanger (5-2), and the heat pump unit, a preheating zone, a low temperature zone, a medium temperature zone, and a high temperature zone with heat gradient ascent in sequence from a fresh air inlet to a fresh air outlet are formed on an air outlet pipeline. By means of the configurations, temperature gradient ascent of fresh air from the fresh air inlet to the fresh air outlet is achieved and heat gradient utilization is implemented. By providing a frostless solution circulation pipeline, frostless operation in winter is implemented. A solution completing frostless operation in the frostless solution circulation pipeline flows back by means of its own weight. Water is separated out from the dilute solution flowing back in the frostless solution circulation pipeline by means of heat exchange, the heat in heat exchange is provided by waste heat of the heat pump unit, and no additional heat pump unit is provided.
