Abstract

The invention discloses a self-adjusting type wax scraping device and a using method and application thereof, and belongs to the technical field of oil and gas storage and transportation. The technical problem that a wax scraping device in the prior art is low in wax scraping efficiency is solved. The self-adjusting type wax scraping device comprises a balancing weight, a connecting rod mechanism, distributed supporting seats, a support lug, an adjusting mechanism and a wax scraping plate, wherein the balancing weight transmits positive pressure to the distributed supporting seats through the connecting rod mechanism. The distributed supporting seats transmit positive pressure to the wax scraping plate through the support lug. The adjusting mechanism is used for adjusting and effectively guaranteeing that the included angle between the wax scraping plate and the inner wall of a storage tank used for containing the wax scraping device is 45 degrees all the time, the adjusting mechanism comprises a supporting seat adjusting hole and a support lug adjusting hole, and the supporting seat adjusting hole and the support lug adjusting hole are matched in size. The two distributed supporting seats can uniformly transfer force to the wax scraping plate, so that all parts of the wax scraping plate are tightly attached to the tank wall in the up-down operation process of a floating disc. The wax scraping device can be automatically adjusted, the included angle between the wax scraping plate and the tank wall is always kept at 45 degrees, and the optimal wax scraping effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of oil and gas storage and transportation, and in particular relates to a crude oil storage tank wax scraping device and a use method. 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 condensate will form on the inner wall of the storage tank that has been running for a long time. However, when the temperature rises, the condensed oil on the inner wall will produce a large amount of VOCs volatile 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 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 oil on the inner w...
