Description

Enhanced separation type raw material gas coalescence separator

Technical Field

Background

In recent years, after the raw material gas conveyed to a purification plant by gas ore is changed into dry gas and dry and wet gas mixed conveying, a raw material gas conveying pipeline is cleaned for many times, a large amount of dust impurities such as ferric sulfide and the like enter the purification plant along with the raw material gas, and large particle impurities and free water are separated through gravity separation and filtration separation, but a large amount of fine solid particles and liquid particles still exist. Solid particles are deposited in an absorption tower tray and a heat exchange equipment tube bundle with relatively slow solution flow velocity, so that heat exchange equipment is blocked, an absorption tower blocks liquid and foams, the effective treatment capacity of raw gas of the device is reduced, and even the product gas is unqualified; the liquid particles combine with the acid gases (hydrogen sulfide, carbon dioxide) in the feed gas to form an acid mist that causes corrosion of the pipeline. Therefore, further filtration separation of the feed gas is required.

The existing raw material gas separation equipment adopts two-stage filtration: the first section of the filtering section is provided with a coalescence filter element, gas passes through the coalescence filter element from outside to inside, solid particles are intercepted by the filtering medium, and liquid particles are gradually coalesced and grown on the inner surface of the filter element due to the coalescence function of the filtering medium. When the liquid drops reach a certain size, the liquid drops fall off from the inner surface due to the impact of the air flow and enter the filter element inner flow passage and then enter the confluence material cavity. In the confluence discharge cavity, larger liquid beads are separated out by gravity settling; the second section is a separation section which is provided with a mist catcher and can effectively catch liquid drops to prevent the liquid drops at the outlet from being entrained, thereby further improving the separation effect.

The existing mist catcher is usually made of a wire mesh, but the wire mesh has a narrow separation load range, and the separation efficiency is sharply reduced after the specified flow rate or liquid-gas ratio of a gas-liquid mixture is exceeded. Along with the increase of the thickness of the wall liquid, the flowing area of the gas is smaller and smaller, the liquid blocking phenomenon can be generated, and the gas-liquid flow velocity is increased; under the above dual influence, the liquid already on the wall will be easily re-entrained by the gas.
