Abstract
The utility model discloses a two-level dust-removal desulfurization device, which comprises a desulfurization tower, wherein the desulfurization tower is provided with a smoke inlet and a smoke outlet, the smoke inlet end is connected with a secondary dust collector, the secondary dust collector is connected with a primary dust collector, and the primary dust collector is provided with an air inlet. Impurities in the gas are removed through two levels of dust collectors, so that the two-level dust-removal desulfurization device has advantages of high dust removal efficiency, low running expense and convenience in maintenance; moreover, a great number of smoke and dust can be intercepted outside the desulfurization device through the dust collectors, the smoke and dust can be prevented from entering the tower, and the smoke and dust can be effectively prevented from being mixed, deposited and blocked with other materials inside the tower to block an air blowing and distribution system inside the desulfurization tower; and meanwhile, the abrasion of a mixing system and a circulating system in the running process of the desulfurization device also can be alleviated, the maintenance load of the entire desulfurization tower system can be reduced, and the overhauling period and the service life of the desulfurization facility can be prolonged.
Description
Technical field
The utility model relates to the chemical industry environmental protection technical field, particularly the two-stage dust removal desulfurizer.
Background technology
Traditional dust-removing desulfurating apparatus complex structure, auxiliary device is many, and investment is large, runs unstablely, directly has influence on the dust-removal and desulfurizing effect of flue gas.
In view of this, the inventor has this case to produce for the defects further investigation of desulfurizer in the prior art then.
The utility model content
In order to overcome above shortcomings part in the prior art, the purpose of this utility model is to provide a kind of two-stage dust removal desulfurizer.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme: the two-stage dust removal desulfurizer, comprise desulfurizing tower, desulfurizing tower has gas approach and exhanst gas outlet, described gas approach end is connected with second level deduster, be connected with first order deduster on the deduster of the second level, described first order deduster is provided with air inlet.
Compared with prior art, the utlity model has following outstanding advantages and effect: the deduster of the utility model by two-stage removes the impurity in the gas, efficiency of dust collection is high, operating cost is low, advantage easy to maintenance, and can be trapped in the flue dust overwhelming majority outside the desulfurizing tower by deduster, avoid flue dust to enter in the tower, can effectively prevent flue dust at Ta Nei and unclassified stores mixes and deposition caking and stop up air blast gas distribution system in the desulfurizing tower; Alleviate again simultaneously the wearing and tearing of stirring system and the circulatory system in the desulfurizer running, reduced the maintenance of whole desulfurizing tower system, prolonged time between overhauls(TBO) and the service life of desulfurization facility.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, the two-stage dust removal desulfurizer, comprise desulfurizing tower 1, desulfurizing tower 1 has gas approach 2 and exhanst gas outlet 3, described gas approach 2 ends are connected with second level deduster 4, be connected with first order deduster 5 on the second level deduster 4, described first order deduster 5 is provided with air inlet 6, the deduster of the utility model by two-stage removes the impurity in the gas, and efficiency of dust collection is high, and operating cost is low, advantage easy to maintenance, and can be trapped in the flue dust overwhelming majority outside the desulfurizing tower by deduster, avoid flue dust to enter in the tower, can effectively prevent flue dust at Ta Nei and unclassified stores mixes and deposition caking and stop up air blast gas distribution system in the desulfurizing tower; Alleviate again simultaneously the wearing and tearing of stirring system and the circulatory system in the desulfurizer running, reduced the maintenance of whole desulfurizing tower system, prolonged time between overhauls(TBO) and the service life of desulfurization facility.
It should be noted that at last: above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
