Embodiment Construction

[0015] Combine below figure 1 , figure 2 The present invention is described below. The positional relationship of up, down, left, right, etc. is based on the attached figure 1 determined by the layout direction.

[0016] The branch pipe 2 extends into the pipe body 1 from the side of the pipe body 1, and the pipe body 1 is a high-viscosity medium pipe or a short connection or other partial pipe sections. The finger tubes 3 are tapered cylinders, and the large ends of the finger tubes 3 are welded together and welded to the branch pipe 2; along the fluid flow direction in the tube body 1, a plurality of finger tubes 3 are radially expanded, and the finger tubes 3 The tip spreads out to the entire cross-section of the tube body 1. On the cross-section of the tube body 1 corresponding to the tip of the finger tube 3, the arrangement density of the finger tubes 3 at the center of the tube body 1 is greater than that of the 3 rows of finger tubes at the edge of the tube body 1....

Abstract

The invention relates to a high-viscosity medium distribution type mixer, which is used in occasions such as high-viscosity medium mixing, high-viscosity medium adding new medium, and the like. Its technical solution: the branch pipe extends into the pipe body from the side of the pipe body, a plurality of finger-shaped pipes are radially expanded and welded to the end of the branch pipe, and the tips of the finger-shaped pipes cover the entire cross section of the pipe body. The invention adopts the method of adding new medium in the high-viscosity medium flow field, relies on the natural flow of the medium to realize mixing, does not need to disturb the fluid, and has small additional resistance.

Description

technical field [0001] The invention relates to a flow-distributing mixer for high-viscosity medium, which is specifically used in the fields of thick oil mixed with thinner viscosity-reducing transportation, downhole heavy oil and thin oil mixing, and can also be used in the occasion of adding new medium to high-viscosity medium in the petrochemical industry. Background technique [0002] As an unconventional petroleum resource, heavy oil is extremely difficult to develop due to its high colloid and asphaltene content, high viscosity, and large flow resistance. In the ground storage and transportation of heavy oil, it is necessary to reduce viscosity and drag to improve its fluidity and reduce power loss and heat loss during transportation. At present, the methods for reducing the viscosity of heavy oil mainly include heating, thinning, and hot water. However, in the mixed-dilute gathering and transportation process, due to the scarcity of thin oil resources in the heavy o...
