Embodiment Construction

[0009] The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0010] A stepless voltage regulation electric desalination experimental instrument of the present invention is mainly composed of a high-voltage power output transformer (1), a low-voltage regulation module (2) and a high-voltage regulation module (3), wherein the high-voltage coil tap of the high-voltage power output transformer (1) is controlled by a high-voltage The tap (6), the low-voltage tap (7), and the zero-point tap (8) are composed of three pieces. ) between 0 ~ 1200v adjustment section. When the high-voltage start button (9) is pressed, the low-voltage start switch KT (4) closes, the low-voltage delay switch KT low (4) pulls in and starts timing the low-voltage on-site residence time. The input voltage is set and adjusted. When the weak electric field setting time ends, the high-voltage time-delay switch KT high (5) pulls in, and the stron...

Abstract

The invention discloses a stepless voltage regulation electric desalination experimental instrument, which is mainly composed of a high voltage power output transformer, a high voltage regulation module, and a low voltage regulation module. 32 high voltage coil taps of the high voltage power output transformer is reduced to 2 high voltage coil taps (0-1200 V regulation section and 0-1750 V regulation section, and 30 taps are reduced. The reeling technology of coils of high voltage power output transformer is simplified, the volume is reduced, the diameter of coils is increased, and thus the output performance is enhanced. The high voltage regulation module and low voltage regulation module adopts an intelligent control module composed of two thyristors. Through the intelligent control modules, the input voltages of weak electric field and strong electric field can be set and adjusted, and the voltage settlement can be carried out without cutting off the power supply.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electrostatic separation of oil-water emulsion, and in particular relates to a stepless voltage-regulating electric desalination experimental instrument for static investigation of electric field conditions of crude oil emulsion. Background technique [0002] Electric desalting and dehydration of crude oil is an important pretreatment process in the refining process of oil fields and refineries. The degree of desalination directly affects the follow-up processing equipment of crude oil, especially the refineries that need to carry out deep processing of crude oil have strict requirements on the desalted crude oil: salt content ≤ 3mg / l, water content ≤ 0.3%. In order to meet this requirement of the refining process, most refineries use electric desalination and electric dehydration equipment. The selection and optimization of operating parameters such as the electric field strength of electri...
