Description

High-efficient multitube whirlwind separator

Technical Field

The utility model relates to the technical field of cyclone separation equipment, in particular to a high-efficiency multi-pipe cyclone separation device.

Background

In the fields of petroleum refining, energy chemical industry, natural gas treatment and transportation, offshore platform and onshore terminal oil and gas exploitation, waste heat and waste heat recovery, pharmacy, papermaking, environmental protection and the like, a key technology which is necessary for carrying tiny heavy phase in light phase flow, especially for carrying tiny solid particles or tiny solid-liquid mixture in the light phase flow to carry out efficient separation purification or recovery treatment is provided.

At present, domestic traditional standard cyclone separators, namely single-cylinder cyclone separators, are still adopted by many enterprises at home and abroad in the industry field and are used for separating solid particles, solid-liquid mixtures or tiny heavy phases from a large amount of light phase flow. The main defects are as follows:

1) the diameter of the cylinder body of the single-cylinder cyclone separator is often several meters, the rotating radius of fluid in the single-cylinder cyclone separator is too large, the separation efficiency of the cyclone separator under the same working condition is inversely proportional to the rotating diameter of the fluid, the separation efficiency is low, a plurality of standard cyclone separators are often adopted or operated in series or in parallel, but higher separation efficiency is still difficult to achieve, and the equipment investment is large;

2) the operation flexibility is narrow, the cyclone separator belongs to a dynamic separator, the separation efficiency is very sensitive to the change of the kinetic momentum of fluid, effective separation is difficult to realize due to too low flow rate, separated heavy phase is re-dispersed into light phase flow due to too high flow rate, and the larger the rotation radius of the fluid in the cyclone separator is, the smaller the operation flexibility is;

3) the heavy phase after primary separation and fine separation is often back-mixed with the light phase flow and carried secondarily seriously, further resulting in reduced separation efficiency and low yield of the heavy phase to be recovered, for example, a catalytic cracking unit in a domestic oil refining plant is a process typically requiring cyclone separation to realize gas-solid separation, and at present, a traditional standard cyclone separator or a slightly modified single-cylinder cyclone separator is mostly adopted, so that the separation efficiency is low, the loss of catalyst is serious, and the abrasion of a flue gas fan is serious.

Therefore, the industries of petroleum refining, energy chemical industry, coal chemical industry, natural gas treatment and transportation, offshore platforms, onshore terminal oil and gas exploitation and the like at home and abroad urgently need to develop a novel efficient cyclone separation form to improve the efficiency of gas-liquid separation and gas-solid separation.
