Dust removal device for treating oil well cement dry-mixed exhaust gas

Abstract

The invention discloses a dust removal device for treating oil well cement dry-mixed exhaust gas. A tank cover for sealing is arranged at the top of a dust removal tank, a gas inlet is formed in the middle-lower portion of the dust removal tank, an exhaust port is located in the top of the tank cover, a solid discharge outlet is formed in the bottom of the dust removal tank, a lower observation port is formed in the lower portion of the dust removal tank, an upper observation port is formed in the tank cover, a communicating pipe for observing liquid level in the dust removal tank is arranged outside the dust removal tank, and supporting legs are arranged at the bottom of the dust removal tank. By using the characteristic that dissolution conditions of gas and solid when passing through water are different to separate solid particles and gas to filter the solid particles and release clean air back into the atmosphere, the separation method is unique, the device is simple in structure and is convenient to use and carry, the dust removing efficiency is high and the device is economic and practical.

Description

technical field [0001] The invention relates to a dedusting device, in particular to a dedusting device for treating the gas discharged from dry mixing of oil well cement, which belongs to supporting tools for petroleum cementing. Background technique [0002] Oil well cement needs to be mixed with treatment agent and external admixture before entering the well to meet the performance requirements of cement slurry. The mixing is carried out in the mixing tank, that is, the use of pressure gas to blow various materials to achieve fluidization, and through the intense collision and diffusion mixing between particles, the purpose of uniform mixing is achieved. When mixing and pouring and emptying, some light-density substances (micro silicon, floating beads, etc.) are discharged out of the tank with the gas; when the tank is cleaned regularly, the remaining materials adsorbed on the tank wall are cleaned into the atmosphere by high-pressure gas. The cement materials discharged...

AI Technical Summary

Problems solved by technology

A filter tank was added in an attempt to use a filter cloth to filter out solid particles in the exhaust gas to reduce pollution, but the effect was not satisfactory. After filtering, the exhaust gas still had dust, and the filter tank was difficult to clean
