The invention discloses a cleaning type industrial boiler system which comprises a rectification unit, a first inverter unit, an induced draft fan, an air blower, a second inverter unit, a PLC controlunit, a hearth pressure collection unit, a DP bus and an inlet wire power supply opening. The cleaning type industrial boiler system adopts the PLC as the control unit, a rectification unit is arranged for a drive unit, a DC bus is shared, and the two inverter driving units are arranged to control the induced draft fan and the air blower separately. The PLC is connected with the inverter units and the rectification unit through the DP communication manner, and a wind shield is directly adjusted to the maximum angle and then fixed. To ensure that the hearth pressure is stable, the PLC collectsthe hearth pressure signal in real time, adjusts and outputs the working frequency of the induced draft fan and the air blower through the intelligent algorithm and controls and adjusts the supply air rate and the exhaust air rate to realize the purpose of stabilizing the hearth negative pressure. Compared with the previous power frequency operating module, a remarkable energy-saving effect is realized and 30% or above energy is saved.
Description
technical field [0001] The invention relates to a boiler system, in particular to a clean industrial boiler system, belonging to the technical field of application of industrial boiler control systems. Background technique [0002] The traditional boiler chamber pressure control method controls the pressure of the furnace chamber by adjusting the angle of the baffle plate of the induced draft fan. In order to ensure that the pulverized coal is fully burned, it is necessary to ensure that the pressure of the furnace chamber is a stable negative pressure. If the air intake is less than the exhaust air volume, the furnace pressure When the pressure is too high, there is a danger of explosion in the furnace; if the air intake is greater than the exhaust air volume, the pressure in the furnace will drop, resulting in insufficient combustion of pulverized coal, air leakage in the furnace, and power consumption of the induced draft fan. Increase. Therefore, controlling and adjusti...
