Abstract

The invention discloses an oil-water separating tower. The oil-water separating tower comprises a liquid distributor tower section, a plurality of circulating device tower sections and a microporous gas distributor tower section, wherein the circulating device tower sections are arranged below the liquid distributor tower section; the microporous gas distributor tower section is arranged below the circulating device tower sections; a microporous gas distributor is in threaded connection with a gas inlet pipe section and is positioned at the lower part of the oil-water separating tower; each circulating device comprises a metal outer barrel, a metal inner barrel, a tapered flow-guiding passage and an oil phase gathering filler; a space between the outer side of the metal inner barrel and the inner side of the metal outer barrel is a circulating flow passage; the oil phase gathering filler is arranged on the upper part of the circulating flow passage; the tapered flow-guiding passage is positioned on the lower part of the metal inner barrel; an upper outlet of the tapered flow-guiding passage is formed inside the inner barrel; and the diameter of a lower outlet is larger than that of the inner barrel. Independent flow passages are provided for separated oil droplets and separated water phase, so that the staying time and the flux of a liquid material can be increased, small-particle size oil droplets can be deeply removed, and the oil-water separating effect can be improved; therefore, the oil-water separating tower is especially suitable for an oil-water separating process with relatively large treatment amount.

Description

technical field

[0001] The invention relates to the technical field of liquid separation, and provides an oil-water separation tower, which is especially suitable for the oil-water separation process with a large processing capacity. Background technique

[0002] Oil-water separation equipment commonly used in industry includes inclined plate degreaser, cyclone degreaser, coarse-grained degreaser, air flotation degreaser, etc. These devices have their own advantages and disadvantages, but generally speaking, the oil removal effect is not ideal, and there are problems such as secondary pollution caused by sludge generation and easy plugging of packing materials. Too large, short liquid residence time, unable to deeply remove small particle size oil droplets (such as emulsified oil, dissolved oil), poor separation effect and other shortcomings. Contents of the invention

[0003] The purpose of the present invention is to provide a new type of oil-water separation tower, whi...

Examples

Embodiment 1

[0027] Example 1: Use the above-mentioned experimental equipment to separate oil and water from industrial waste liquid. The process is as follows: fill the device with industrial waste liquid at normal temperature and pressure, then introduce microbubble gas into the device, adjust the two-phase flow rate to be stable, and carry out Continuous and stable operation. The operating industrial waste liquid flow rate is 1t / h, the main component is the emulsion of organic oil phase and water, of which the oil phase content is 70%; the gas flow rate is 20m 3 / h. By adopting the oil-water separation tower of the present invention, the yield of oil is 97%, which is 25% higher than that of other processes.
