The invention discloses a
drying equipment energy-saving transformation method based on a permanent
magnet synchronous high-speed fan, and relates to the technical field of
drying equipment control and
airflow conveying, and the
drying equipment energy-saving transformation method comprises the steps that adjacent drying grooves are divided into a drying groove group; original hot-air blowers of all the drying grooves are detached, and permanent
magnet synchronous high-speed blowers are installed; an
electric heating bag is arranged in a communicating pipeline between the main air
pipe and the plurality of
branch air pipes; a tank body temperature sensor, a heating bag outlet temperature sensor, an exhaust temperature and
humidity sensor and an
exhaust valve are arranged and connected into the
electrical control device;
control software is operated in the
electrical control device to control the operation frequency of the permanent
magnet synchronous high-speed fan, the
heating power of the
electric heating bag and the opening degree of the
exhaust valve. A large number of original air heaters which are independently installed are omitted, the situation that
airflow is unstable due to performance differences of the multiple air heaters is reduced, the
air volume and the air pressure in the same drying groove set are kept consistent, the overall stability of air supply is improved, and the number of vibration sources caused by parallel operation of the multiple air heaters is reduced.
