Description
Technical field
The utility model relates to environment-friendly processing units, are exactly that a kind of flue gas disappears white device.
Background technique
After flue gas have passed through flue gas ash removal and wet desulphurization, major pollutants are cleaned, but flue gas is saturation after wet process
Wet flue gas, comprising the entrainment of a large amount of liquid water and vaporous water in flue gas, in a large amount of steam of wet desulphurization discharge, there are many dissolutions
Salt and other non-dissolved matters generate a large amount of superfine particulate matters after being dehydrated in an atmosphere, become invisible particle.These ultra-fine
Grain object is hidden in air, and it is long to stay aloft the time, does not settle, and has extremely strong transfer ability, control and difficulty of governance are very
Greatly.Quiet steady weather or inversion weather are encountered, and absorbs water, expand, adhere to, become larger, causes environmental pollution, simultaneously because wet desulphurization
Flue gas is saturation wet flue gas afterwards, therefore flue gas after desulfurization has certain corrosivity, can corrode flue and chimney, after wet desulphurization
The coloured plume and white cigarette formed also results in certain sense organ pollution, therefore each state all by white cigarettes such as wet desulphurizations and has in research
The method that color plume is eliminated.
More popular method is using gas-gas heat exchanger GGH at present, its effect will be after desulfurization using former flue gas
Neat stress is heated, and reaches exhaust gas temperature on dew point, mitigates " gypsum rain " phenomenon, mitigates the corruption to flue and chimney
Erosion reduces chimney anticorrosion maintenance cost, improves the diffusance of pollutant；It is lowered into the flue-gas temperature on absorption tower simultaneously, reduces
To corrosion-resistant process specifications in tower.But the mass-transfer efficiency of GGH is low, figure is huge, and cost is high, while GGH heat transfer sheet
It is thin, while being contacted with low-temperature flue gas section, therefore and be easy to cause heat transfer sheet burn into heat transfer sheet knot ash that heat conductive mass is caused to decline,
Service life is lower.
In addition low low-level (stack-gas) economizer MGGH can be used, its effect is added the flue gas after desulfurization also with former flue gas
Heat can also make exhaust gas temperature reach dew point or more, essentially identical with GGH basic role, MGGH using water as heat transferring medium,
High temperature section flue gas heats water, reaches low-temperature zone, and low-temperature zone flue gas is heated up with hot water and is heated, while water is cooled down.MGGH is adopted
It is exchanged heat with aqueous medium, solves GGH heat exchanger etching problem, the service life is higher, but needs to increase water pump and provide for heat transfer medium
Power cycle, operating cost is higher, simultaneously because heat exchange efficiency is low there are two-part heat exchange, may cause exhaust gas temperature shakiness
It is fixed, and figure is huge, and cost is high.
