Problems solved by technology

Most of the existing demisters are in the form of folded plates, and their demisting effect is better, and the limit particle size can reach about 25 microns. Because of the restriction of the secondary entrainment, the working speed cannot be too high, so I want to further reduce the limit Particle size is very difficult

Embodiment Construction

[0029] Hereinafter, the present invention will be further described in detail by taking the embodiment of the accompanying drawings as an example. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0030] A high-efficiency condensing tube bundle demisting device, such as figure 1 and figure 2 As shown, the device includes multiple sets of upper and lower condensation tube bundle devices 2, water inlets 4, water outlets 7, condensed water collectors 8, and condensed water drains 9 arranged in parallel and spaced intervals on the tower 1. The bottommost A condensate collecting device is installed on the inner wall of the tower below the condensing tube bundle device to collect the flue gas condensed water condensed by the condensing tube bundle device in the tower. , the other end of the condensed water drain extends to the outside of the tower to discharge the flue gas condensed water in the conde...

Abstract

The invention relates to a high-efficiency condensation tube bundle defogging device. The device includes multiple groups of condensation tube bundle devices arranged in parallel at intervals above and below the tower, a water inlet, a water outlet, a condensed water collecting device, and a condensed water drain. A condensed water collector is installed on the inner wall of the tower below the condensed tube bundle device at the lowest level. The condensed water collector is connected with the condensed water collector and provided with a condensed water drain. The other end of the condensed water drain extends to the outside of the tower. . This device rebuilds the existing demister, and adds a condensing device to the lower part of the two-layer demister, so as to improve the effect of demister and dust removal. This device can not only reduce the limit particle size of the demister, but also achieve The effect of reducing the droplet concentration at the outlet of the demister is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and relates to the transformation and application of a flue gas demisting device at the outlet of an absorption tower in wet flue gas desulfurization technology, in particular to a high-efficiency condensing tube bundle demisting device and its application. Background technique [0002] Among flue gas desulfurization technologies, wet desulfurization technology is the most widely used. Its core equipment is the absorption tower, and the flue gas washed by the absorption tower is saturated wet flue gas at about 50°C. At the same time, the dissolved and suspended particles in the water will also be discharged into the atmosphere, causing secondary air pollution. [0003] In order to reduce the discharge of liquid droplets, the existing technical means is to install a mist eliminator on the top of the absorption tower. Most of the existing demisters are in the form of fol...
