Anti-precipitating device of water-coal-slurry storage tank

Abstract

The invention discloses an anti-precipitating device of a water-coal-slurry storage tank. The anti-precipitating device is characterized by comprising a tank body, a plurality of vertical type stirrers, a blower, side stirrers and a turbulator, wherein the tank body is provided with a tank cover and a plurality of slurry outlets; the vertical type stirrers are uniformly distributed in the tank body along the center of the tank body; the vertical type stirrers are fixedly arranged between the bottom wall of the tank body and the tank cover; the blower comprises a main through pipeline which is arranged outside the side wall of the bottom of the tank body, a plurality of branch pipes, a plurality of valves and an air compressor; each branch pipe is provided with an independent valve; the main through pipeline is connected with the air compressor; and the air compressor is used for blowing compressed air into the tank body through the main through pipeline and the branch pipes. The anti-precipitating device radically solves the anti-precipitating problem of the water-coal-slurry storage tank, so that water-coal-slurry can have fluidity like water so as to be convenient for long-distance transportation; and the anti-precipitating device has anti-precipitating effect better than that of other ways, can effectively solve potential safety hazards in operation of the storage tank, and can relieve logistical clearing pressure of enterprises.

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.
