Optimisation and improvement of bell jar valve for large sulphur-burning sulphuric acid plant
The bell jar valve is the core equipment for controlling the inlet temperature of one section of bed layer in the converter of sulphuric acid plant,and the original bell jar valve has such problems as the spool of refractory casting material falling off,the spool of the valve tampering and swinging,the packing seal leaking,the temperature regulation performance is poor,and the site must be operated manually,which seriously restricts the safe and stable operation of the sulphuric acid plant in a long period of time.The problems of the bell jar valve are analyzed,and the structure,adjustment performance and control mode of the bell jar valve are optimized and improved to achieve the expected results.
