Coal-water slurry storage tank anti-sedimentation device

Abstract

The invention discloses an anti-sedimentation device for a coal-water slurry storage tank, which is characterized in that it comprises a tank body, several vertical agitators, purging devices, side agitators and spoilers, and the tank body is provided with a tank cover and A number of slurry outlets, vertical agitators are evenly distributed in the tank along the center of the tank, the vertical agitator is fixed between the bottom wall of the tank and the tank cover, and the purger includes a side wall arranged outside the bottom of the tank The main pipe, several branch pipes, several valves and air compressors, each branch is provided with a separate valve, the main pipe is connected to the air compressor, and the air compressor blows compressed air into the tank through the main pipe and branch pipes. The present invention fundamentally solves the anti-sedimentation problem of the coal-water slurry storage tank, enables the coal-water slurry to have the fluidity like water for long-distance transportation, has better anti-sedimentation effect than other forms, and can effectively solve the problem of storage tank operation safety Hidden dangers, reducing the pressure on corporate logistics cleanup.

Description

technical field [0001] The invention relates to the technical field of coal-water slurry machinery, in particular to a coal-water slurry storage tank anti-sedimentation device with novel structure design and good anti-sedimentation effect. Background technique [0002] Coal water slurry is a flowable coal-based fluid fuel similar to petroleum. It is made by grinding and refining coal, water and a small amount of additives, and fully mixing them with water. Coal water slurry has good fluidity and stability, and can be stored and transported like petroleum. It is safe and pollution-free. It is a clean fuel suitable for popularization. At present, storage tanks are routinely used in the industrial production of coal water slurry. Additives in coal water slurry generally include dispersants and stabilizers, which can improve the fluidity of coal water slurry to a certain extent. Because the coal water slurry is a solid-liquid dispersion system, when the coal water slurry is st...

AI Technical Summary

Problems solved by technology

However, there is no effective device for preventing the precipitation of coal-water slurry on the market at present, and a large amount of hard precipitation is still prone to occur. Therefore, it is necessary to design a storage device for coal-water slurry with good anti-sedimentation effect, strong practicability and high reliability.
