Description

A set of demisting dedusting deodorization desulphurization plant and its demisting dedusting deodorization sulfur removal technology
Technical field
The present invention relates to environmental protection industry (epi), more particularly to a set of demisting dedusting deodorization desulphurization plant and its demisting dedusting deodorization Sulfur removal technology.
Background technology
The absorption plant pattern of wet desulfurizing process has spray column, liquid column tower, sieve-plate tower, packed tower, drum both at home and abroad at present Steep tower etc., wherein at home and abroad proportion is more than 98% to spray column in wet desulfurizing process, be the cigarette of main flow both at home and abroad at present Desulfurization tower, spray absorber desulfurization device has the features such as technology maturation, technique are simple, desulfuration efficiency is high, resistance is small, also simultaneously With the problems such as energy consumption is big, adjustability is poor, absorbing liquid entrainment is big.Problem Producing reason is as follows:A, spray column are carrying out flue gas It is time of contact by SO2 and absorbing liquid and collision frequency during desulfurization to complete the chemical reaction of acid-base neutralization, due to spray The absorbing liquid of pouring is that the SO2 in dispersed phase, flue gas is also dispersed phase, and dispersed phase is to dispersed phase to reach very high desulfurization degree just It is required that residence time of the flue gas in tower is long as much as possible(Cause tower body will height)It is big with liquid-gas ratio(Cause the absorption carried Liquid is more), therefore, the potential energy work(that spray column is done when carrying out flue gas desulfurization is just big in the extreme, thereby results in carrying absorbing liquid Circulation pump power is big, and power consumption is high;B, the design of spray column are according to exhaust gas volumn, SO2 contents, absorbent activity, desulfurization The factors such as rate, crystallization time determine the flue gas flow rate in tower, liquid-gas ratio and tower body height, when spray column is run, if pot Stove load and ature of coal(Sulfur content is not above design load)During change, it can only be mediated by changing the spray number of plies, it is difficult to Correspondence variable quantity is adjusted in right amount;When absorbent changes or discharge standard changes, spray column is difficult to regulation, can only to this Spray column is transformed;C, the desulfurization method due to spray column be by the way of flue gas and absorbing liquid adverse current, so can be with Increase chemical reaction kinetic energy is due to that the convection current of flue gas and absorbent causes serious entrainment phenomenon to improve desulfurization degree, Therefore the problem of being formed demister over-burden, if processing is bad will to cause chimney rain.
The content of the invention
It is an object of the invention to provide a set of desulfurization deodorization energy consumption is small, adjustability is good, absorbing liquid carries small demisting dedusting secretly Deodorization desulphurization plant and its demisting dedusting deodorization sulfur removal technology.
