The invention discloses a heat adsorption type
drying machine with a three-
tower structure and an adsorption regeneration technology of the heat adsorption type
drying machine, and belongs to the technical field of adsorption type
drying machines. The dryer comprises three adsorption towers, a regeneration
system and a PLC
control system, adsorbents are arranged in the adsorption towers, and the regeneration
system comprises an electric heater and an
air blower which are connected through a steel
pipe. According to the dryer, the purpose of saving energy is achieved through the peak-valley-flat
electricity price, the adsorption
tower A, the adsorption
tower B and the adsorption tower C conduct adsorption in the
daytime, the regeneration and cold blowing process is conducted when the valley
electricity price is utilized, and therefore the operation cost of the dryer is reduced; the adsorption regeneration process comprises two working
modes: in the first working mode, adsorption is carried out for 12 hours in a tower A, adsorption is carried out for 12 hours in a tower B, and adsorption is carried out alternately in a tower C; and a second working mode: one tower performs adsorption work, one tower performs heating regeneration, and the other tower can perform cold blowing. The adsorption dryer with the three-tower structure can meet the requirement of a customer for reasonably selecting an off-peak
electricity period for heating regeneration, so that the operation
electric energy of equipment is greatly reduced.
