Summary of the invention

The utility model is in order to overcome the defective that above-mentioned prior art exists, but provide a kind of simple in structure, can dedusting the bitubular eddy flow bubbling dust-removal and desulfurizing smoke eliminator of desulfurization again.

The utility model is achieved through the following technical solutions: a kind of bitubular eddy flow bubbling dust-removal and desulfurizing smoke eliminator, it comprises the urceolus that has air inlet and exhanst gas outlet, be provided with inner core in the urceolus, inner core is fixed in the urceolus by upper sealing plate and following shrouding, be provided with helical form eddy flow plate between described urceolus and the inner core, be provided with sprayer unit between eddy flow plate blade, described shrouding down is provided with discharge pipe and playpipe.

Other features of the present utility model also have: be provided with eaves shape baffle plate in the described inner core, can make flue gas along the walking of baffle plate broken line, strengthen removing fog effect.

Described sprayer unit circulating pump connects circulatory pool, helps recycling to dust-removal and desulfurizing solution.

Adopt hollow cone tangent type nozzle in the described sprayer unit, the big spray effect of its unobstructed diameter is good, and can save the water source, makes reaction more thorough.

The top of described urceolus is provided with the flue gas demister, can remove the water smoke in the flue gas of discharge.

The beneficial effect of this programme can be learnt according to the narration to such scheme, described bitubular eddy flow bubbling dust-removal and desulfurizing smoke eliminator, urceolus have air inlet and exhanst gas outlet and in be provided with inner core, inner core is fixed in the urceolus by upper sealing plate and following shrouding, be provided with helical form eddy flow plate between described urceolus and the inner core, flue gas constantly changes direction in rotary course, making it be the eddy current shape moves downward, strengthened the reaction time and the response area of absorbent solution and gas, on the basis of improving its efficient, made its reaction more fully complete.Be provided with sprayer unit between eddy flow plate blade, can spray vaporific aqueous vapor and remove impurity and harmful substance in the flue gas.Spray nozzle adopts hollow cone tangent type nozzle, and its unobstructed diameter ambassador reaction is more thorough.Described shrouding down is provided with discharge pipe and playpipe, and flue gas is through the playpipe bubbling, and the liquid level of solution of tube bottom top forms froth bed outside, and the contact area of gas and liquid and time of contact are increased, and mass-transfer efficiency improves.Eddy flow plate place finishes the purified treatment first time of flue gas in this type of design, the froth bed place of flue gas above solution carries out double purification, the gas cleaning rate is increased substantially, and it uses maintenance very simple, applied range, in use can not occur stopping up or scale formation long service life.The utilization rate of equipment and installations height, operating cost is low, and is energy-saving and cost-reducing.Be applicable to various desulfurization dust-removing technique.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
