Problems solved by technology

For example, the foam overflows through the inlet flue and enters the booster fan, which will damage the booster fan or cause serious corrosion, and in severe cases, the fan can be scrapped; It is also impossible to observe the internal situation, so it is often not known that the lining of the tower has fallen off until the tower wall is corroded and the slurry leaks.
[0007] In the case of the above failures, not only economic losses are caused, but also the power plant is interrupted in its production work
In addition, it will also make the flue gas desulfurization work unable to proceed smoothly
Even, some enterprises directly discharge flue gas into the atmosphere in order to ensure power production, which seriously pollutes the air.

Abstract

The present invention relates to a desulfurization absorption column. Said desulfurization absorption column includes an absorption column self-body, raw flue gas inlet set in the middle-lower portion of said absorption column self-body, slurry spraying layer set over the raw flue gas inlet in the middle-upper portion of absorption column self-body, demister set over the spraying layer, cleaned flue gas outlet set in the top portion of the described absorption column self-body and observation window which is communicated and connected with the portion above conventional working level of the described absorption column self-body.

Description

technical field [0001] The invention relates to a desulfurization absorption tower, in particular to an absorption tower used for wet flue gas desulfurization in thermal power enterprises. Background technique [0002] As we all know, the problem of environmental pollution has been widely concerned by all walks of life, and to some extent, it is urgent to solve the problem of environmental pollution. [0003] Among them, for some cities in our country, air pollution is the top priority of environmental pollution problems. Trace it to its cause, on the one hand, because the emission of automobile exhaust increases year by year, on the other hand, it is due to the exhaust gas emission problem of heavy industry. [0004] In fact, the vast majority of enterprises have paid enough attention to the issue of exhaust emissions. However, compared with western developed countries in the prevention and control of environmental pollution, our country has a shorter history of technologi...
