Description
Technical field
The utility model relates to a kind of chimney, particularly relates to a kind of corrosion-resistant chimney.
Background technology
The EGT produced in high-temperature coking process can reach 250 DEG C to 290 DEG C, and containing a large amount of corrosive substances such as nitride, sulfide in waste gas, corrodible chimney lining, makes liner rot to cause cylindrical shell to ftracture.
Authorization Notice No. is disclose a kind of boiler chimney with high temperature resistant, anticorrosion, antiseep in the patent of CN 100365240C, only can stand the resistance to 150 DEG C of high temperature of burn into that the sour gas of less than 40 DEG C and acid dew drips non-leakage, the discharge of high-temperature coking waste gas can not be met.
Authorization Notice No. is the liner disclosing a kind of long-life high temperature high-strength corrosion-resisting chimney in the patent of CN 202852848 U, can resist medium-term and long-term 50 DEG C of-160 DEG C of alternate runs of chimney and short-term 200 DEG C of high-temperature flue gas, can not meet the discharge of high-temperature coking waste gas.
Summary of the invention
The purpose of this utility model is to provide a kind of corrosion-resistant chimney, can resist the long-term corrosion of high-temperature coking waste gas, can resist the operation of medium-term and long-term 250 DEG C of-290 DEG C of high-temperature flue gas of chimney simultaneously, meet the discharge of high-temperature coking waste gas.
The utility model is achieved through the following technical solutions:
A kind of corrosion-resistant chimney, it is characterized in that: the inner side of shell body is provided with stainless steel inner core, the inner surface of stainless steel inner core is provided with lining coating, described lining coating is followed successively by active carbon layer, alkali-free glass fiber cloth, adhesive layer, carbon cloth, thermal insulation layer, glass flake coatings, potsherd from the inside to surface, wherein active carbon layer is close to stainless steel inner core, and active carbon layer thickness is 3-5mm, and insulation thickness is 8-12mm, glass flake coatings thickness is 8-10mm, and potsherd thickness is 5-8mm.
The utility model glass flake coatings thickness is 8-10mm, and potsherd thickness is 5-8mm, adopts double layer anticorrosive structure, and increases the thickness of anticorrosive coat, can strengthen the defensive ability/resistance ability of chimney to nitride, these corrosive substances of sulfide in high-temperature coking waste gas.Thermal insulation layer adopts thickness to be 8-12mm ceramic fiber cloth, can the high temperature of resistance to 800-1000 DEG C, can resist the operation of medium-term and long-term 250 DEG C of-290 DEG C of high-temperature flue gas of chimney.Owing to being subject to corrosion and the effect of high/low temperature temperature shock of acidic flue gas, after long-time use, anticorrosive coat and thermal insulation layer can be subject to certain damage, now sour gas will enter inner liner, and then corrosion stainless steel inner core, and thickness is the adsorbable sour gas of active carbon layer of 3-5mm, avoid it to the corrosion of stainless steel inner core.The double shielding of alkali-free glass fiber cloth and carbon cloth, can prevent the leakage of active carbon, and adhesive layer is used for alkali-free glass fiber cloth and the carbon cloth of being adhesively fixed.
Beneficial effect: the utility model adopts double layer anticorrosive structure, antiseptic effect is better, can resist the long-term corrosion of high-temperature coking waste gas, can resist the operation of medium-term and long-term 250 DEG C of-290 DEG C of high-temperature flue gas of chimney simultaneously.
