A dishwasher having a speed-controlled induction motor coupled to a pump to drive the pump during dishwasher operation. A motor controller is connected to the induction motor to control the speed of operation of the induction motor. A dishwasher controller is connected to the motor controller for sending signals to, and receiving signals from, the motor controller during operation to control the motor speed. The flow rate of water through the pump discharge to a spray arm is controlled based on the phase of the wash cycle and the condition of the filter that blocks food debris from entering the sump. The motor speed is decreased to decrease the pump flow rate when the flow rate through the filter decreases in an early phase of the wash cycle. The motor speed is increased to increase the pump flow rate during later phases of the wash cycle. In steady state operation, the flow rate through the filter is matched to the flow rate through the pump discharge.

The invention provides devices for purifying converter gas by dry process and using afterheat of the converter gas and a method thereof. In a converting period, waste gas exhausted from the converter is cooled by a movable gas hood and a vaporizing cooling duct, then is sent into a gravity dust collector to reduce dust content thereof, is conducted into a flue and then to an afterburning afterheat boiler; the afterburning afterheat boiler generates overheated vapor by using large quantity of sensible heat of the converter gas and sends the converter gas after being cooled into a bag dust collector through the flue to purify; the purified converter gas is sent to a draft fan to be pressurized through the flue, then passes through a three-way valve, and is sent to a converter gas cabinet; in a non-blowing period of the converter, converter gas is not generated; afterburning afterheat boiler burns a certain amount of blast furnace gas to stabilize load thereof and vapor yield. The three-way valve is switched to cause the afterheat boiler waster gas exhausted from the draft fan to flow to a waste gas discharging chimney. The converter gas processed by the method and devices has very low dust and moisture contents and is an ideal purified gas. During the operation process, large quantity of industrial water is saved, and large quantity of secondary energy is recycled.
