Orientation coalescence liquid-liquid separator

Abstract

The invention discloses an orientation coalescence liquid-liquid separator which comprises a cylinder (5), a trapezoidal inlet hole box (3), a rectification plate group (4) and a coalescence plate group (7). The orientation coalescence liquid-liquid separator is characterized in that the coalescence plate group (7) is corrugated plate packing; a corrugated plate is fixedly supported by a pull rod distance tube (14) and a hoop (15); the corrugated plate is arranged in an angle of 45 degrees with the horizontal axis. Compared with a conventional pore box, the trapezoidal inlet hole box is somehow improved, so that the impact of flow to a separation field of the equipment is reduced, at the same time relatively good functions of gravity energy dissipation and washing are achieved, and pre-separation can be effectively achieved. A periodic harmonic wave is adopted as the waveform curve of the coalescence plate group, so that the fluid flowing state can be switched between laminar flow and periodic harmonic wave pulsating flow, and collision and agglomeration of droplets are facilitated; due to adoption of the multi-layer inclined corrugated type composite coalescence plate, the oil droplet removal efficiency is improved.

Description

technical field [0001] The invention relates to an orientation and liquid-condensing separator, which belongs to a liquid-liquid separator that is industrially immiscible and has a density difference, and is especially suitable for mixing liquids with different specific gravity, such as oil and water, between them at the same time form an interface. Background technique [0002] Oily wastewater comes from the processing, refining, storage and transportation of petroleum and oil products in the petroleum industry; cooling lubricants, steel rolling water, etc. produced in the process of machinery manufacturing; locomotive wastewater in the transportation industry, wastewater from oil washing tanks in railway locomotive depots, etc. Wastewater from the food industry, textile industry and other manufacturing industries also contains a large amount of oil. At present, the water content of crude oil produced from oil wells in most oil fields is too high, the total volume of produ...

Problems solved by technology

But the coalescing plate pack itself also brings some problems

[0006] First, due to the reasons of the coalescing plate group itself, such as poor heat resistance, weak impact resistance, etc., the coalescing plate group will be broken during the production process, and some fragments will enter the oil outlet and water outlet valve with the oil flow. , to block the outlet of the equipment, thus greatly reducing the separation efficiency

[0007] Second, the addition of the coalescing plate group will increase the resistance drop of the fluid flow. If the resistance drop is too large, it will affect the separation efficiency and cause an increase in additional costs.
