Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figure 1-Figure 2 As shown, the present invention consists of a chimney 1, a swirl ring 2, a warm air cylinder 3, a warm air chamber 4, a fan 5, an air-cooled condenser 6, a drain pipe 7, a chimney partition plate 8, a deflector plate 9, and a smoke outlet interface 10. Composed of steering cover 11, demister 12, and smoke return interface 13.

[0020] The chimney 1 is partitioned by the chimney partition plate 8, and four windows are opened on the upper and lower sides, respectively connected to the flue gas outlet interface 10, the flue gas return interface 13, and the air-cooled condenser 6. Four air-cooled condensers 6 are symmetrically arranged, with stainless steel-aluminum finned tubes as heat exchange elements, and the upper and lower processes are connected by a steering cover 11 .

[0021] The flue gas flows and condens...

Abstract

The invention relates to a whitening system for mixing flue gas outside a condensing warm air chimney. It includes a chimney, which is characterized in that the chimney is separated by a chimney partition plate and a plurality of windows are respectively opened on the upper part and the lower part, and a plurality of air-cooled condensers are symmetrically arranged on the periphery of the chimney, and the air-cooled condenser is provided with a smoke outlet interface for docking The lower window is provided with a flue gas return interface to connect with the upper window, the outlet end of the flue gas return interface is equipped with a tangential swirling deflector, the air-cooled condenser is equipped with a finned tube, and the flue gas flows through the finned tube ; The upper part of the air-cooled condenser is provided with a fan, the upper outlet of the fan is connected to the warm air chamber, and the upper part of the warm air chamber is provided with a warm air cylinder. The invention has the advantages of small size, light weight, no auxiliary system, simple engineering installation, good whitening effect, low investment and low operating cost.

Description

technical field [0001] The invention relates to a flue gas whitening technology, in particular to a flue gas whitening system mixed outside a condensed warm air chimney. [0002] technical background [0003] After the flue gas or other exhaust gas is sprayed and purified, it becomes saturated wet flue gas, which carries a large amount of water vapor. When it is discharged from the chimney and is cooled, it will condense and form white vapor, which seriously pollutes the visual environment. At the same time, the wet flue gas also carries PM2.5 particles such as slurry droplets, dust, and aerosols that have not been removed, which is also a kind of pollution to the atmosphere. If the wet flue gas can be condensed before being discharged, it can not only eliminate the white smoke plume of the chimney, but also further reduce the emission of PM2.5 such as slurry droplets, dust, aerosol, etc., and recover a large amount of condensed water, which is the first choice for deep contr...
