Abstract

The invention discloses a self-regulating wax scraping device, a use method and an application thereof, belonging to the technical field of oil and gas storage and transportation. It solves the technical problem of low wax scraping efficiency of the wax scraping device in the prior art. It includes a counterweight, a linkage mechanism, a distributed support, lugs, an adjustment mechanism and a wax scraper. The counterweight transmits positive pressure to the distributed support through the linkage mechanism; The positive pressure is transmitted to the wax scraper; the adjustment mechanism is used to adjust and effectively ensure that the angle between the wax scraper and the inner wall of the storage tank for placing the wax scraper is always 45 degrees. The adjustment mechanism includes a support adjustment hole and a support The ear adjustment holes match the size of the two. The two distributed supports can evenly transmit the force to the wax scraper to ensure that all parts of the wax scraper are closely attached to the tank wall during the up and down operation of the floating plate; the wax scraper device of the present invention can be automatically adjusted to realize scraping The wax plate and the tank wall always maintain a 45-degree angle to ensure the best wax scraping effect.

Description

technical field [0001] The invention belongs to the technical field of oil and gas storage and transportation, and particularly relates to a wax scraping device for a crude oil storage tank and a method for using the same. Background technique [0002] Crude oil contains components such as wax and colloid. When the temperature is low, wax will form on the inner wall of the storage tank, and a layer of wax condensation will form on the inner wall of the storage tank after long-term operation. However, when the temperature rises, the condensed oil on the inner wall will produce a large amount of volatile VOCs gas, which will be discharged into the atmosphere and cause environmental pollution. Therefore, it is urgent to develop a high-efficiency wax scraping device to reduce the wax hanging on the inner wall of the storage tank and achieve VOCs emission reduction. [0003] As an important accessory of the crude oil storage tank, the wax scraping device can remove the condensed ...
