Abstract

The invention discloses a steam recycling system for a steam dewaxing vehicle. The system comprises an oil pumping pipe, an outer shell and a steam isolating layer. The outer shell and steam isolating layer are cylindrical. The steam isolating layer is arranged on the inner side of the outer shell. A cavity is formed between the outer shell and the steam isolating layer. The upper portion and lower portion of the cavity are sealed. A plurality of steam inlets are formed in the surface of the cavity. A plurality of steam injection holes are formed evenly in the wall body of the steam isolating layer. Gaps are formed between the inner side of the steam isolating layer and the oil pumping pipe. Oil pumping pipe wall body steam recycling pipes are arranged at the bottom of the gaps. According to the steam recycling system for steam dewaxing vehicle, by arranging the oil pumping pipe wall body steam recycling pipes, liquefied liquid and non-liquefied steam are directly discharged out of a well mouth; since the recycled liquid and steam are returned back to the steam vehicle by the oil pumping pipe wall body steam recycling pipes, and waste of steam is reduced.

Description

technical field [0001] The invention relates to the field of petroleum equipment, in particular to a steam recovery system for a steam wax removal vehicle. Background technique [0002] At present, the main method of wax removal in oil fields is on-site wax removal by steam truck. Because of the high-temperature steam operation during the cleaning process, the steam truck needs to waste a lot of steam during the washing process, which leads to a large waste of energy and low efficiency. 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 in 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 through following technical scheme: [0005] The steam recovery system of the steam wax removal veh...
