Abstract
The utility model discloses a composite stainless steel desulfurizing tower for sintering machine smoke gas government, which comprises a desulfurizing tower body, wherein the top of the desulfurizing tower is connected with a smoke discharge pipeline, the desulfurizing tower body consists of a plurality of different-temperature-section tower bodies, the upper part of the tower body is an upper low-temperature section, the lower side of the upper low-temperature section is connected with a medium-temperature section, the lower side of the medium-temperature section is connected with a high-temperature section, the lower side of the high-temperature section is connected with a lower low-temperature section, and the tower bodies of the upper low-temperature section, the medium-temperature section, the high-temperature section and the lower low-temperature section from top to bottom are all tower bodies made of stainless steel. The composite stainless steel desulfurizing tower adopts stainless steel composite plates as tower body materials, the whole desulfurizing tower does not need anti-corrosion treatment, high-temperature resistance is realized, and the service life is long.
Description
Technical field
The utility model relates to a kind of composite stainless steel desulfurizing tower that sintering device flue gas is administered that is used for.
Background technology
The characteristics of sintering device flue gas have:
1, flue gas SO
2Change in concentration is big, at 400～4000mg/m
3More than.
2, flue-gas temperature changes greatly, can be from 80 ℃ to 180 ℃.
3, flue gas flow changes greatly, up to more than 40%.
4, flue gas moisture content is big, between 10～13%, and unstable.
5, flue gas oxygen content height is between 15～18%.
6, flue gas contains multiple pollution composition, except that containing sulfur dioxide, dust, also contains heavy metal, dioxin, nitrogen oxide etc.
Domestic sintering machine desulfuration tower commonly used mainly contains now: spray absorber, bubble tower or the like.Be applied to different sulfur removal technologies such as calcium method, ammonia process.
In engineering practice, anti-corrosion materials such as spray absorber, bubble tower carbon steel glass inner-lining scale, liner vinyl rubber.But because the sintering device flue gas variations in temperature is big, particularly main exhauster plays compression to flue gas, improves flue-gas temperature more than 20 ℃.The flue-gas temperature that enters desulfurizing tower is up to more than 200 ℃, and general glass flake is difficult to bear, and influences service life of equipment.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, a kind of composite stainless steel desulfurizing tower that sintering device flue gas is administered that is used for is provided, and it adopts stainless steel clad plate as composition of tower shell material, and whole desulfurizing tower need not preservative treatment, high temperature resistant, long service life.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of composite stainless steel desulfurizing tower that sintering device flue gas is administered that is used for, and comprises the desulfurizing tower tower body; Described desulfurizing tower top connects smoke discharging pipe, described desulfurizing tower tower body is made of a plurality of different temperatures section tower bodies, tower body top is the top low-temperature zone, connect middle-temperature section below the low-temperature zone of top, connect high temperature section below the middle-temperature section, connect the bottom low-temperature zone below the high temperature section, top low-temperature zone, middle-temperature section, high temperature section and bottom low-temperature zone tower body are the stainless steel material tower body from top to bottom.
The utility model according to sintering device flue gas contain S amount, flue gas contains Cl
-Amount selects for use stainless steel clad plate as composition of tower shell material, and whole desulfurizing tower need not preservative treatment.In desulfurizing tower different temperatures section, adopt different materials, can adopt 304 stainless steel materials, middle-temperature section to adopt 316 stainless steel materials, high temperature section to adopt the 316L stainless steel material as low-temperature zone, during the welding tower body,, adopt stainless steel transition zone welding rod in carbon steel base layer material and stainless steel cover material junction, at inner wall of tower cover material place, employing is similar to the welding of cover material material, makes tower body can bear the flue-gas temperature that enters desulfurizing tower and be up to more than 200 ℃ that service life of equipment is long.

The utility model according to sintering device flue gas contain S amount, flue gas contains Cl
-Amount selects for use stainless steel clad plate as composition of tower shell material, and whole desulfurizing tower need not preservative treatment.In desulfurizing tower different temperatures section, adopt different materials, can adopt 304 stainless steel materials, middle-temperature section to adopt 316 stainless steel materials, high temperature section to adopt the 316L stainless steel material as low-temperature zone, during the welding tower body,, adopt stainless steel transition zone welding rod in carbon steel base layer material and stainless steel cover material junction, at inner wall of tower cover material place, employing is similar to the welding of cover material material, makes tower body can bear the flue-gas temperature that enters desulfurizing tower and be up to more than 200 ℃ that service life of equipment is long.
The utility model is applicable to 36～450m
2Sintering machine.
It should be noted that at last: obviously, the foregoing description only is for the utility model example clearly is described, and is not the qualification to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the present utility model.
