Abstract

A tubular condensation water and mist removal device comprises a gas treater casing, a tubular demister, a demister cooling water header or pipe and a flushing water pipe, wherein the tubular demisteris formed by cooling pipes or finned cooling pipes in staggering, coiling or fold-back arrangement, is of a Venturi structure and is provided with a demister cooling water inlet, the demister coolingwater header or pipe, a demister cooling pipe and a demister cooling water outlet which are communicated; a demister and a gas port are arranged in the gas treater casing; a flushing pipe of the demister is arranged above the tubular demister. The problem of poor visual effect of flue gas discharge of a gas purification device is solved, environmental pollution is reduced, a purifier recycling rate can be further increased, water in gas is recovered, water consumption of a wet purification device is reduced, the technological economy and the environmental protection effect of the device are improved, and the device is particularly applicable to advanced treatment of purified flue gas of flue gas desulfurization.

Description

[0001] Technical field: [0002] The invention belongs to the field of environmental protection, and relates to a device for wet gas purification, in particular to a method and device for tube-type condensation dehydration and demisting, and is especially suitable for deep treatment of flue gas through wet flue gas desulfurization. [0003] Background technique: [0004] Wet gas purification has high efficiency and reliable operation. However, after the wet treatment, the clean flue gas is entrained with pollutants such as droplets of the absorbing liquid, smoke dust, and absorbents. In order to reduce the discharge of these pollutants, the current process generally uses 2-3 layers of mist eliminators to treat the clean flue gas, and this solution can only remove the droplets of the absorption liquid with a particle size of 20 μm or more. Fine particles have little effect. The emitted gas is heavy white, blue and other smoke clouds that are difficult to diffuse, forming a lon...
