Abstract
The invention relates to a tank type calcinator, and particularly relates to a large countercurrent tank type calcinator for the anode, cathode, electrode and carbon graphitization material for aluminum production in the carbon industry. The large countercurrent tank type calcinator comprises a material tank, fire paths arranged on the two sides of the material tank, a front wall and a rear wall; a volatile matter collecting channel is arranged above the material tank; a front wall volatile matter vertical path is arranged in the front wall; a rear wall volatile matter vertical path is arranged in the rear wall. The large countercurrent tank type calcinator provided by the invention has the advantages that since the motion directions of the smoke and material are opposite, the material can be sufficiently preheated when entering the material tank, a calcining zone of the calcinator is lengthened while the exhaust gas temperature is reduced, and the calcinator capacity is increased that the capacity of the countercurrent tank type calcinator is 15-20% larger than that of a fair-current tank type calcinator with the same size as the countercurrent tank type calcinator. The smoke flow conforms to the physical laws, and the pressure loss in the fire paths is relatively low. Meanwhile, the material heating law is obvious, and the maximum calcining temperature can be increased so that the product quality is improved and the true density generally exceeds 2.08g/cm<3>. Moreover, for the calcining raw material of high volatile matter, the phenomenon of burner fire can be solved without adopting a special channel for the countercurrent tank type calcinator, and a perfect effect is realized on the calcinator emission.
Description
Technical field
The present invention relates to a kind of can-type calcine furnace, relate in particular to a kind of carbon industry and produce the large-scale countercurrent pot-type calcining furnace of aluminium anode, negative electrode, electrode and charcoal element graphitized material.
Background technology
Along with continuous increase, particularly Large aluminum electrolytic plant and the electrode factory of modern Tan Su enterprise production capacity, when the production capacity of carbonaceous product improves constantly, also more and more stricter to the requirement of calcined coke quality.Electrolytic bath electric current increases gradually now, and anodic current density increases, and level of automation improves gradually, therefore the specification of quality of carbon anode is also improved gradually.Calcining is the slubbing operation of anode product, and the quality of calcined coke has determined the quality of anode to a great extent.Conventional calciner is rotary kiln and following current pot furnace in the market, but nearest 2 years, and raw materials cost promotes greatly, and following current pot furnace is because burning quality is high, and scaling loss is little etc., and feature occupies leading market gradually.But energy consumption is larger, the maximization calciner of therefore inventing a kind of synergy that more lowers consumption is imperative trend.
Summary of the invention
The present invention is the large-scale countercurrent pot-type calcining furnace of one proposing in order to address the above problem, and the clean withdrawal rate of single tank is more than 150kg/h.Object is when raw materials cost and specification of quality all promote now, further reduces scaling loss, improves the quality of products on the basis of following current pot furnace advantage, improves single tank production capacity simultaneously.
For reaching the large-scale countercurrent pot-type calcining furnace of above-mentioned purpose the present invention, comprise batch can, be located at quirk, front wall and the Hou Qiang of batch can both sides, the top of batch can is provided with fugitive constituent and concentrates passage, is provided with the perpendicular road of front wall fugitive constituent in front wall, after be provided with within the walls the perpendicular road of rear wall fugitive constituent.
Batch can is rectangular parallelepiped, and batch can horizontal section is of a size of 2180 × 360mm, and short transverse is 7034mm; Two batch cans are a row, and four batch cans are one group, the each one group of quirk that distributes in both sides of a blow-down drum.
Quirk is 8 layers, every layer of roundabout connection of quirk, and every layer of quirk height is 680mm.
Every layer of described quirk height comprises that one deck draws brick height, and drawing brick height is 68mm.
Every layer of described quirk separates with silica brick.
The perpendicular road of front wall fugitive constituent is communicated with fugitive constituent and concentrates passage and the 8th layer of quirk.
Lead to the 8th layer of quirk Shu road and be provided with fugitive constituent arm-tie.
The perpendicular road of rear wall fugitive constituent is communicated with fugitive constituent and concentrates passage and the 7th, five and first floor quirk.
Seven, five and the ingress of first floor quirk be equipped with fugitive constituent arm-tie.
The 8th layer of quirk ingress of rear wall is provided with arm-tie.
First floor quirk is communicated with flue, and batch can below is provided with watercooling jacket.
The below of the 8th layer of quirk is provided with preheated air passage.
The entrance of described preheated air passage after being all located within the walls.
Preheated air passage connects the 8th layer of quirk by the perpendicular road of front wall preheated air after from rear wall to front wall.
Described front wall and the insulating brick of rear wall are respectively silica brick, fireclay brick, light weeight alumina brick and common brick from the inside to the outside.
Advantageous effect of the present invention: the present invention is because the direction of motion of flue gas and material is contrary, material can carry out sufficient preheating in entering batch can, in reducing funnel temperature, extend stove calcining zone, increase stove production capacity, the adverse current of same size and following current pot furnace, the approximately large 15-20% of the former productivity ratio the latter.Flow of flue gas is more followed physics law, and quirk internal pressure loss is less.Simultaneously the material rule of being heated is obvious, can improve the highest calcining temperature, thereby improve the quality of products, and true density generally reaches 2.08g/cm
3above.And for the calcining raw materials of high-volatile, countercurrent pot-type stove, without adopting specific channel just can solve the burner phenomenon of burning with anger, discharges and plays good effect stove.
