Steam self-circulation device of wax removing vehicle

Abstract

The invention discloses a steam self-circulation device of a wax removing vehicle. The steam self-circulation device comprises an oil pumping pipe, and also comprises a cylindrical shell; the shell is of a hollow structure, and the oil pumping pipe is arranged in the middle of the shell; a plurality of steam introduction pipes are evenly arranged on the outer surface of the inner wall of the shell, and the axes of the steam introduction pipes are parallel to the axis of the shell; steam introduction openings are formed in the tops of the steam introduction pipes, a plurality of air discharging holes are evenly formed in the portions, close to a highline of the oil pumping pipe, on the outer surfaces of the steam introduction pipes, and pipe-liquid recycling holes are formed in the bottoms of the steam introduction pipes; a guiding device is arranged at the bottom of the shell, and is an uncovered hollow cylinder, the upper side of the guiding device is connected with the outer surface of the shell, the bottom of the guiding device is of a positive cone structure with a circle center as the vertex, and an oil-pumping-pipe-wall steam recycling pipe is connected to the edge of the bottom. According to the steam self-circulation device, wax removing operation can be thoroughly carried out, steam can be recycled, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of petroleum equipment, in particular to steam self-circulation equipment for wax removal vehicles. Background technique [0002] At present, the main method of wax removal in oilfields is on-site wax removal by steam trucks. Because of the high-temperature steam operation during the cleaning process, the steam trucks need to waste a lot of steam during the flushing process, which leads to a large waste of energy and low efficiency; and the high-temperature steam temperature is high. It is easy to cause burn accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is that a large amount of steam needs to be wasted during the washing process of the steam car, which leads to a large waste of energy and relatively low efficiency. At the same time, the steam or liquefied liquid is recovered to avoid excessive waste of energy. [0004] The present invention realizes thro...
