摘　　要：在L型进渣阀半工业试验台上,针对表观引渣风风速在0～25 m/s、引渣风管深入比例0～0.6、联箱压力0.05～0.15 MPa、试验物料粒径1.32～2.22 mm时,对该进渣阀的进渣特性进行了试验研究。试验结果表明:随着表观引渣风风速增大,进渣阀进渣速率先增大后减小;进渣速率随引渣风管深入比例的增大、试验床料颗粒平均粒径的增大而减小,随联箱压力的增大而增加。此外,还得到了进渣特性的关联式,关联式的计算值与测量值吻合较好,可用于指导进渣阀的调节。On a L type slag inlet valve semi-industrial test rig,experimentally studied were the slag admission characteristics of a slag inlet valve when the apparent slag induced air speed ranges from 0 to 25 m/s,the insertion depth proportion of the slag-induced air tube is between 0 and 0.6,the pressure in the header is in a range from 0.05 to 0.15 MPa and the particle diameter of the test material from 1.32 to 2.22 mm.The test results show that with an increase of the apparent slag induced air speed,the slag inlet speed at the slag inlet valve will first increase and then decrease,it will decrease with an increase of the insertion depth proportion of the slag induced air tube and the average particle diameter of the test material and will increase with an increase of the pressure in the header.Moreover,the correlation formula controlling the slag admission characteristics was also obtained.The values calculated by using the correlation formula are in relatively good agreement with those measured,thus the formula can be used to guide the regulation of the slag inlet valves.
