GAS FLOW PULSATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To correspond to a large treatment flow rate and to enable the formation of a narrow pulse flow. SOLUTION: This apparatus has a first flange 14 having a plurality of solenoid valves 11 to which a gas flow is supplied attached thereto and having the jet orifices of the gases from the respective solenoid valves 11 formed therein, the second flange 21 opposed to the first flange through a packing 22 and supplying the gas to the downstream area where a narrow space allowing the gas pulse flows from the respective solenoid valves to meet with each other and a control means for controlling the on-off times and operation timings of the respective solenoid valves and gas pulse flows are ejected from the respective valves at the same time to be allowed to meet with each other to be converted to a large pressure gas pulse flow.
