The invention relates to a
heat pump and
molecular sieve adsorption turning wheel
combined cycle organic solvent recycling device. The
heat pump and
molecular sieve adsorption turning wheel
combined cycle organic solvent recycling device comprises an internal cycle pipeline, a sub pipeline and a
branch pipeline, wherein the internal cycle pipeline comprises a gas inlet, an internal cycle fan, a
gas heater and a gas outlet; the gas inlet is communicated with a gas outlet of a
coating machine; the gas outlet is communicated with a gas inlet of the
coating machine; the sub pipeline comprises the gas outlet of the
coating machine, an exhaust fan, a hot gas introducing and discharging opening of a gas-gas
heat exchanger, an air cooler, an
evaporator of the high-temperature
heat pump, an
evaporator of a low-temperature heat pump, a condenser of the low-temperature heat pump, a condenser of the high-temperature heat pump, a cold gas introducing and discharging opening of the gas-gas
heat exchanger and a gas inlet; the
branch pipeline comprises a
branch pipeline gas inlet, an adsorption area of a
molecular sieve concentration turning wheel, a
processing fan and a branch pipeline gas outlet; the branch pipeline gas inlet is connected with a gas outlet of the
evaporator of the low-temperature heat pump, and the branch pipeline gas outlet is communicated with a machine head and a machine
tail of the coating machine. According to the device, a heat pump is used for recycling an
organic solvent, and meanwhile the gas temperature is increased, so that energy sources are saved; meanwhile,
zero emission under the condition of saving the coating energy sources is realized.
