Abstract
The invention discloses a novel carrier gas circulation dehumidification drying process system which comprises a carrier gas heater, a drying machine, a cyclone dust collector, a bag-type dust collector, a film dehumidifier, an adsorption dehumidifier and a regeneration heater, and the carrier gas heater is communicated with the drying machine; the top of the drying machine is sequentially connected with the cyclone dust collector and the bag-type dust collector; the bag-type dust collector is connected with the membrane dehumidifier; the membrane dehumidifier is connected with the adsorption dehumidifier; and the adsorption dehumidifier is connected with the regeneration heater. According to the novel carrier gas circulation dehumidification drying process system, the membrane dehumidifier and the adsorption dehumidifier are combined to remove humidity in circulation carrier gas, cooling is not needed in the dehumidification process, the energy utilization rate of the circulation carrier gas is increased to 85% or above, meanwhile, waste gas emission is reduced to 15% or below, more energy is saved, low carbon is achieved, and environment friendliness is achieved. The method can be widely applied to the carrier gas circulation drying field.
