Description
Technical field
The utility model belongs to the industrial furnace apparatus field of carbon goods green compact roasting, specifically discloses a kind of carbon goods stoving oven.
Background technology
Stoving oven is carbon goods pressed compact under stopping composition protection, carries out the industrial furnace of high-temperature heat treatment, also can be used for the carbon goods thermal treatment again after impregnating pitch.In a word, by roasting, the pitch in blank is carbonized, make carbon goods have higher physical strength, lower resistivity, good thermostability and chemical stability, stoving oven is the visual plant in carbon production of articles.Circular furnace with cover, the industrial furnace such as tunnel furnace or drawer kiln of carbon production of articles manufacturing concern many uses open type for many years, fuel is mainly producer gas, Sweet natural gas or coal etc.
As everyone knows, containing a large amount of pitch in carbon goods green compact, pitch along with temperature the polymerization of a rising part and coking becomes coke is retained in carbon goods.And the pitch of another part, account for pitch total amount 40% constantly to decompose in heat-processed, volatilization, with fuel products of combustion together by chimney discharged to air.So not only cause the huge waste of resource, and a large amount of bitumen flue gas causes serious pollution discharged to air to environment.People adopt electrolemma cleaning apparatus to process bitumen flue gas for this reason, and due to flue gas enormous amount and again extreme temperatures not easily processes, often also unsatisfactory after the process of electrolemma fly-ash separator.
The roasting of carbon goods green compact is carried out in coke beds, needs to add a large amount of granuliform coke as stopping composition during shove charge, has had a strong impact on on-the-spot Working environment.
In addition because carbon baking furnace is open type, the infiltration of unavoidable air when stoving oven is in pre-heating stage, in coke beds, the provide protection of coke to green compact occurs over just the temperature be obviously oxidized higher than coke.Namely also kiln can not protect carbon element green compact not oxidated before 400 DEG C, and now in air, the existence of oxygen can aggravate the cohesion of pitch, coking and decomposition, and this also causes the yield rate of product not high, and this roasting for large size goods is extremely important.
