Abstract
The utility model discloses an improved flue gas desulfurizer for an atmospheric pressure hot water boiler. The improved flue gas desulfurizer comprises an atomizing chamber with a flue gas inlet, an outlet and a drain outlet, wherein the atomizing chamber is internally provided with an alkali liquor atomizer connected with a pump and an alkali liquor tank, two groups of spoilers are arranged between the alkali liquor atomizer and the flue gas inlet, and the first group of spoilers and the second group of spoilers are arranged on the two sides of the inner wall of the atomizing chamber in a staggered manner. The improved flue gas desulfurizer provided by the utility model is simple in structure, reasonable in design, low in manufacturing cost and high in desulfurizing efficiency; as flue gas suffers from low resistance when passing through the desulfurizer, the desulfurizer can be applied to the atmospheric pressure hot water boiler which naturally induces air and exhausts flue gas by a chimney.
Description
Technical field
The utility model relates to a kind of devulcanizer, particularly relates to a kind of smoke devulcanizer for atmospheric water-heating boiler.
Background technology
The flue gas of normal-pressure hot-water boiler does not generally have desulfurizer, and high-temperature flue gas directly enters atmosphere after boiler self smoke abatement and dust control, and this way is unfavorable for environmental protection, can cause atmosphere pollution.Therefore, on the existing commercial plant, can adopt various washings or caustic wash tower to be used for removing of sulfur dioxide, but, because column plate, filler resistance are too large, the atmospheric hot-water pot that all can't be used for the natural induced draft burning protects, and existing desulfurizer desulfuration efficiency is not high.
Summary of the invention
The purpose of this utility model just is to provide a kind of energy to be used for normal-pressure hot-water boiler, and the modified smoke devulcanizer for atmospheric water-heating boiler that desulfuration efficiency is high can solve the problems of the technologies described above fully.
To achieve these goals, the technical solution adopted in the utility model is such:
A kind of modified smoke devulcanizer for atmospheric water-heating boiler, comprise have gas approach, the spray chamber of outlet and sewage draining exit, be provided with the alkali lye atomizer in the spray chamber, the alkali lye atomizer is connected with pump, lye tank (vat), be provided with spoiler between alkali lye atomizer and the gas approach, described spoiler has two groups, first group of spoiler and second group of interlaced spray chamber inwall both sides that are arranged on of spoiler.
As preferably, described first group of spoiler and second group of spoiler all are tilted to lower setting.
This structure is conducive to reacted spent lye and flows into smoothly the spray chamber bottom surface.
As preferably, the spray chamber inner bottom surface tilts to sewage draining exit.
This structure is conducive to spent lye and flows to sewage draining exit and discharge.
The course of work of the present utility model is as follows:
This flue gas desulfurization device is connected between boiler flue gas outlet and the chimney, pump is drawn the alkali lye in the lye tank (vat) from the alkali lye atomizer and is sprayed, the alkali lye that atomizes in spray chamber carries out neutralization reaction with reverse contact of the sulfur dioxide gas in the flue gas, flue gas after the purification is discharged through chimney from exhanst gas outlet, reacted spent lye, is discharged from sewage draining exit downstream to the spray chamber bottom surface along spoiler.
Compared with prior art, the utility model has the advantage of:
Simple in structure, reasonable in design, cheap, desulfuration efficiency is high, and flue gas is little by this devulcanizer resistance, can be used in the normal-pressure hot-water boiler with the smoke evacuation of chimney natural induced draft.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of modified smoke devulcanizer for atmospheric water-heating boiler, comprise and have gas approach, outlet 2,3 and the spray chamber 1 of sewage draining exit 7, be provided with alkali lye atomizer 4 in the spray chamber 1, alkali lye atomizer 4 and pump 5, lye tank (vat) 6 connects, be provided with spoiler between alkali lye atomizer 4 and the gas approach 2, described spoiler has two groups, first group of spoiler 9 and second group of spoiler 8 interlaced being tilted to down are installed in spray chamber 1 inwall both sides, wherein a spoiler size near gas approach 2 can shelter from gas approach 2 fully, prevents that reacted spent lye from flowing into gas approach 2.Spray chamber 1 inner bottom surface tilts to sewage draining exit 7.The alkali lye that pH value 〉=8.5 are arranged in the lye tank (vat) 6, used alkali can be sodium carbonate or sodium acid carbonate.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
