Measurement of Bulk Modulus and Study of its Impact on Transport Characteristics for Dense Paste

Article Preview

Abstract:

Dense paste is solid-liquid waste from industry production and sewage disposal process with high concentration and viscosity. It has large output, low utility rate and serious environmental pollution. While the engineering application of long-distance and large-diameter pipeline transportation solve the disposal of dense paste, the serious back-flow causes that actual throughput is far less than the theoretical. It is relevant to dense paste bulk modulus, which there has no related study. In this paper, we carried out a test on coal slime based on wave speed method theory. We get the bulk modulus by measuring the propagation speed of pressure wave in the pipe, and analyze its impact on actual throughput and effective stroke of piston.Verification shows that the scheme is feasible and provides reference for the further study between bulk modulus and transport characteristics.
