Research and Design of High Frequency Cleaning Pulse Angle Valve
The high-frequency cleaning pulse angle valve is an important device in the reverse blowing cleaning system of the coal gasification device.It is used to provide high-frequency pulse airflow to the ceramic or metal sintered fly ash filter rod,blowing away the coal ash attached to the filter,to prevent high pressure difference or even rod breakage in the filtering system caused by coal ash deposition.The polycrystalline silicon industry is mainly used in silicon powder filtration systems for CDI(reduction tail gas sepa-ration),cold hydrogenation,trichlorosilane synthesis,and other devices.It is also widely used in dusty systems such as cement,steel mills,and refining.Through the design of external pressure corrugated pipe structure,floating connection between valve core and valve stem,special structural design of valve seat sealing ring,special accessory configuration,performance testing such as strong pressure and leakage,prototype life test,fast action time test,CAE flow rate simulation,pressure simulation,simulation of casting parts casting,and impact simulation of valve seat sealing ring,the design is more reasonable.The high-frequency cleaning pulse an-gle valve developed has fast switching speed The advantages include good blowing effect,long service life,high leakage level,reliable sealing,convenient maintenance,and stable and reliable operation.This study not only effectively solves the technical problems of high life,high precision,zero leakage,and bellows sealing required for high-frequency cleaning pulse valves,but also has reference significance for valve design under frequent operating conditions.
