Impurity separator applicable to high temperature and high viscosity fluid

Abstract

The invention discloses an impurity separator applicable to high temperature and high viscosity fluid. The impurity separator comprises an outer tank; the outer tank comprises a tank body, an upper cover, a fluid inlet pipe, an inner cylinder and a fluid outlet pipe, wherein the cross section of the outer tank is in a round shape, the upper cover seals the top of the tank body, the fluid inlet pipe is arranged on the tank body along the tangent of the tank body, the inner cylinder is concentrically arranged in the tank body and fixedly connected with the bottom face of the outer tank, a predetermined gap is maintained between the upper edge of the inner cylinder and the upper cover, the fluid outlet pipe penetrates through the upper cover and extends into the inner cylinder, and a predetermined gap is maintained between the lower end of the fluid outlet pipe and the bottom face of the inner cylinder. By means of the impurity separator, the high temperature and high viscosity fluid enters an annular area between the tank body of the outer tank and the inner cylinder in the tangential direction through the fluid inlet pipe and is rotated, in the rotation process, large-grained rust sediment, welding slag and other impurities are separated out and accumulated at the bottom under the effect of gravity, meanwhile, through the design of a stopper ring of the inner cylinder, the impurities which are separated out through rotation can be prevented from entering the inner cylinder, and the separating effect is improved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an impurity separator suitable for high-temperature and high-viscosity fluid. Background technique [0002] Pipeline transmission is a commonly used method in industrial production. When transporting high-temperature and high-viscosity fluids, such as heated asphalt, insulation pipelines are generally used for transmission. However, welding slag will inevitably exist in the pipeline. Or rust residue and other impurities, if not removed, will cause damage to pipelines and other equipment, how to effectively remove impurities has become an urgent problem to be solved. [0003] Chinese patent 201420233629.6 discloses an online heat transfer oil hydrocyclone sedimentation separator, which includes a hydrocyclone chamber and a sedimentation chamber. The spiral diversion groove assembly is designed to prolong the attenuation time of the heat transfer oil flow rate and increase the ...

Problems solved by technology

[0004] However, for asphalt-like high-temperature and high-viscosity fluids, the design of the spiral diversion groove assembly results in excessive loss of flow velocity, which is unfavorable for on-line cleaning of dense impurities such as rust slag or welding slag.
