Assembling method of electrostatic coalescence electrode sealing device

Abstract

The invention relates to an assembling method of an electrostatic coalescence electrode sealing device, which comprises the steps that plugs are arranged at the two ends of an electrode manifold, electrode tube holes are evenly distributed in the front side of the electrode manifold, sealing plugs are arranged in the electrode tube holes, electrode tube inserting holes are formed in the sealing plugs, fixing holes are formed in the rear side of the electrode manifold, and sealing bolts are screwed in the fixing holes; a sealing ring is arranged between the sealing bolt and the front end of the fixing hole, a gasket is arranged at the rear end in the fixing hole, a screw is arranged in the middle of the front end face of the electrode tube, the electrode tube is correspondingly inserted into the electrode tube insertion hole, and the front end of the screw is in threaded connection with a nut. The condition that the electrode manifold is prone to leakage due to the fact that an original sealing plug sealing structure and the electrode manifold are different in material under the high-temperature working condition is avoided, longer operation of the electrodes can be guaranteed, the sealing performance of the electrodes and the sealing device is improved, it is guaranteed that high-voltage electricity of the insulated electrodes is conveyed to each electrode in the insulated and sealed environment, the damage rate of the insulated electrode is reduced, the dehydration efficiency is effectively improved, the operation power consumption is saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of crude oil-water separation, in particular to an assembly method of an electrostatic coalescence electrode sealing device. Background technique [0002] In recent years, as most oilfields in my country have entered the late stage of exploitation, on the one hand, the water content of the produced fluid has increased, and the water content of the produced fluid in some offshore oilfields can reach more than 99%. The produced fluid in many oilfields is seriously emulsified, which brings many problems to the conventional oil-water separator: 1. Due to the high water content, poor properties and serious emulsification of the produced fluid, the water content may be high after passing through the conventional oil-water separator, and entering the electric dehydration equipment will cause An increase in current, or even a trip, will affect the safe and stable operation of the electric dehydration equipment. At the...

[0002] In recent years, as most oilfields in my country have entered the late stage of exploitation, on the one hand, the water content of the produced fluid has increased, and the water content of the produced fluid in some offshore oilfields can reach more than 99%. The produced fluid in many oilfields is seriously emulsified, which brings many problems to the conventional oil-water separator: 1. Due to the high water content, poor properties and serious emulsification of the produced fluid, the water content may be high after passing through the conventional oil-water separator, and entering the electric dehydration equipment will cause An increase in current, or even tripping, will affect the safe and stable operation of the electric dehydration equipment, and at the same time, the increase in current will increase the power consumption of the electric dehydration equipment

2 Due to the low efficiency of conventional oil-water separation equipment, multi-stage separation is required to meet the water content requirements of crude oil, which will inevitably lead to problems such as a large number of equipment, increased floor space, high investment, and increased operation and maintenance costs

3. The inferior quality of crude oil and the application of additives lead to serious emulsification of crude oil production fluid. In addition, the poor effect of conventional oil-water separation will lead to excessive oil content in drainage, which will bring great pressure to sewage treatment and environmental protection. How to solve the existing static electricity The coalescing electrode sealing plug has a cumbersome structure, expands when exposed to heat, and is easy to leak, which has become a technical problem that has been difficult to solve for a long time
