Problems solved by technology

At present, the large amount of purified air-carrying liquid (fine droplets or mist) generally leads to the following problems: 1. Increase in lye and water consumption; 2. Corrosion and blockage of rear equipment (reheater, induced draft fan, etc.); 3. With a large amount of water, the increase in humidity affects the diffusion and aggravates the smog. When the amount of lye is large, the fine lye particles lose water and form white ash to pollute the atmosphere and aggravate the smog.
People also often use wire mesh components in the process of gas dehydration and demisting, but in the case of gas containing impurities, it may cause the equipment to be blocked

Embodiment Construction

[0015] See figure 1 The front end of the horizontal equipment housing 2 is a gas inlet 1 and the rear end is a purified gas outlet 5. Several layers of auxiliary horizontal separation plates 3 are arranged at the front, and (several rows) of labyrinth screens are arranged at the inner and rear parts. For the wire mesh blocks 4 arranged in section, the cross-sectional void ratio between the wire mesh blocks 4 is 30% to 60%, and the longitudinal projections of the horizontal gaps of two adjacent rows of wire mesh blocks 4 do not overlap.

[0016] see figure 1 , the gas containing liquid droplets enters from the gas inlet 1, and first flows in the narrow gap flow channel of the auxiliary horizontal separation plate 3, and the larger droplets quickly settle down, and the gas carries the fine droplets and continues to flow forward, entering the labyrinth mesh area. The fine droplets are adsorbed and captured by colliding with the screen block 4, and the recovered liquid falls to t...

Abstract

A low-pressure-drop gas deliquoring and demisting method belongs to the technical fields of gas-liquid two-phase separation, environmental protection, and process equipment, and is used to solve the problem of gas carrying liquid. Including gas entry, purified gas discharge, and recovery liquid discharge, its features are: a wire mesh-strengthened separation maze is designed in the vertical or horizontal sedimentation separation space, and the fine liquid carried by the gas is adsorbed and captured by alternately overlapping the wire mesh and the gaps. Drops, and avoid the solid impurities carried by the gas from clogging the equipment. Also provided is a labyrinth screen apparatus for carrying out the method of the invention. It is used for gas-liquid two-phase separation, gas dehydration, and gas defogging, with low pressure drop and high efficiency.

Description

technical field [0001] The invention belongs to the technical fields of gas-liquid two-phase separation, environmental protection, and process equipment, and in particular relates to a method and equipment for deliquoring and demisting gas with low pressure drop. Background technique [0002] Flue gas, waste gas dust removal, desulfurization treatment process usually adopts lye washing method, spray or even atomize lye in the washing tower to make it fully mixed with flue gas and waste gas, to wash and absorb dust, remove SO2 reaction, and purify The gas is discharged from the top of the scrubber. At present, the large amount of purified air-carrying liquid (fine droplets or mist) generally leads to the following problems: 1. Increase in lye and water consumption; 2. Corrosion and blockage of rear equipment (reheater, induced draft fan, etc.); 3. The increase of humidity with a large amount of water affects the diffusion and aggravates the smog. When the amount of lye is la...
