Problems solved by technology

[0003] The traditional demulsifier dosing device cannot dilute the concentration of the demulsifier during the dosing process. If the concentration of the demulsifier is high and the amount of the demulsifier added is too much, it will cause a lot of waste of the demulsifier. However, the existing The flowmeter is not directly calculated by volume, so there is a certain error

Abstract

The invention provides a demulsifier feeding device and a using method thereof, and particularly relates to the technical field of feeding equipment. The demulsifier feeding device comprises an outer shell, wherein a demulsifier storage cavity is formed in the outer shell, and a rotating shaft is arranged in the demulsifier storage cavity; an inner cavity is formed in the cavity wall of the demulsifier storage cavity, a through hole is formed between the inner cavity and the demulsifier storage cavity, and an outlet pipe is arranged at the upper end of the inner cavity; a mixing cavity, a water box and a water tank are arranged in the outer shell; a water pump is arranged on the water box, fixing rods are arranged on the outer shell and the water tank, a rotating rod is arranged between the fixing rods, a spiral pipe is arranged on the side wall of the rotating rod, and a rotating angle sensor is arranged on each fixing rod; a water receiving hopper is arranged below the upper end of the spiral pipe; an impeller stirrer is arranged in the mixing cavity; the side wall of the mixing cavity is composed of a transparent plate; volume scale marks are arranged on the transparent plate; and a mixture outlet is formed in the mixing cavity. According to the demulsifier feeding device and the using method, the demulsifier can be accurately and quantitatively diluted, and a large amount of waste of the demulsifier is avoided.

Description

technical field [0001] The invention belongs to the technical field of dosing equipment, and in particular relates to a demulsifier dosing device and using method. Background technique [0002] A demulsifier is a surfactant that breaks up an emulsion. The demulsifier mainly destroys the emulsion by partially replacing the role of the stable film. Used as a dehydrating agent, it can remove the water in crude oil and heavy oil, so that the water content can meet the requirements; it can reduce the viscosity of crude oil when used in oil wells, so that the oil wells will not be blocked. The demulsifier is obtained by polymerization of fatty alcohol, propylene oxide and ethylene oxide; easily soluble in water, light yellow or milky white viscous liquid. The aqueous solution is milky white. [0003] The traditional demulsifier dosing device cannot dilute the concentration of the demulsifier during the dosing process. If the concentration of the demulsifier is high and the amou...
