Method for measuring slurry concentration in pipeline

Abstract

The invention discloses a method for measuring the slurry concentration in a pipeline and relates to measurement of the slurry concentration in dredging and hydraulic fill projects. The invention provides a measuring method for slurry concentration in a pipeline, and the method is environment-friendly, reliable, economic, practical and free from limitation of the pipe diameter. According to the measuring method for slurry concentration in the pipeline, measurement connecting pipe sections which are connected in a conveying pipeline in series are adopted. The method for measuring the slurry concentration in the pipeline is characterized in that a plurality of conductivity sensors are evenly installed on the measurement connecting pipe sections, the conductivity sensors transmit the measured conductivity output signals to a data acquisition instrument through shielding cables, the data acquisition instrument is connected with a personal computer (PC), the PC sets up backstage analyzing processing software according to the conductivity of the slurry under different concentrations, and the backstage analyzing processing software calculates the slurry concentration in the pipeline by means of the collected conductivity data. The method for measuring the slurry concentration in the pipeline can be used for a cutter suction type or a trailing suction type dredger in the dredging and hydraulic reclamation projects or on occasions where the slurries are conveyed by means of pipelines.

Description

technical field [0001] The invention relates to a method for measuring mud concentration in dredging and reclamation engineering. Background technique [0002] Real-time, fast and accurate measurement of mud concentration by cutter suction boats and trailing suction boats in the process of dredging and filling is very important. The most commonly used measurement method at present is to use the gamma ray density meter. The principle is that when the gamma ray passes through the material, the intensity of the ray is weakened due to the photoelectric effect and scattering effect, and the degree of attenuation and the density of the material follow the index. law. The gamma density meter is a non-contact measuring instrument. Although the instrument has high measurement accuracy and does not require maintenance, it also brings unavoidable shortcomings. If it is used improperly, it will cause radioactive pollution to the surrounding environment and cause radioactive radiation ...

Problems solved by technology

Although the instrument has high measurement accuracy and does not require maintenance, it also brings unavoidable shortcomings. If it is used improperly, it will cause radioactive pollution to the surrounding environment and cause radioactive radiation damage to personnel; if it is stolen, it will bring unpredictable damage. damage; equipment maintenance, transportation, and storage conditions are harsh, and supervision is strict. It must meet the hygienic requirements for the use of radioactive sources, and a radioactive material use certificate must be required; if the use time is too long, the scaling on the inner wall of the tube will affect the measurement accuracy; diameter < 200mm), the measurement error is large; the equipment is expensive, etc., and various shortcomings have brought a lot of inconvenience during use, limiting its use
