Demister

Abstract

The invention relates to a demister. The demister comprises a primary demisting device and a secondary demisting device, wherein the primary demisting device consists of a primary demisting drum and aprimary ring cone plate; the secondary demisting device consists of a secondary demisting drum and a secondary ring cone plate; the secondary demisting drum is arranged in a tower body at the lower part of a gas outlet; the secondary ring cone plate is arranged below the secondary ring cone plate; the primary demisting drum is arranged on the outer side of the secondary demisting drum; the bottomof the primary demisting drum extends to be blow the secondary ring cone plate; the primary ring cone plate is arranged below the primary demisting drum; an annular gap is reserved between the primary demisting drum and the primary ring cone plate, as well as between the secondary demisting drum and the secondary ring cone plate; a main body of the primary ring cone plate, as well as a main bodyof the secondary ring cone plate, is of a conical structure of which the middle is high and the periphery is low; a water storage tank is arranged on the outer circumference of the primary ring cone plate, as well as the outer circumference of the secondary ring cone plate; and the water storage tank of the primary ring cone plate is further connected with a downcomer. The two stages of demistingdevices are adopted to realize continuous twice demisting of a gas medium, and the demisting efficiency is effectively improved.

Description

technical field [0001] The invention relates to a demister device, in particular to a demister used for separating gas from the entrained mist. Background technique [0002] In the chemical industry, a demister is installed on the top of many towers to reduce the entrainment of mist in the gas. At present, the main demisters include inertial demisters, swirl plate demisters, wire mesh demisters, etc. The purpose is to separate suspended liquid particles from the gas medium. However, most of these defoaming devices are single-layer defoaming devices, which rely on one defoaming process to remove the mist entrained in the gas. The structure is simple and the defoaming efficiency is not high. Contents of the invention [0003] The invention provides a demister, which uses a two-stage demister device to realize two consecutive defoaming processes of the gas medium, effectively improving the defoaming efficiency; wherein the wire mesh defoaming structure is simple and light, a...
