Description
The utility model relates to a kind of after baking device of carbon product, is applicable to the after baking and the bakes to burn the article of various carbon products, also can be used for the roasting of other bituminizing goods.
The after baking of existing carbon product is to adopt the tunnel kiln roasting furnace roasting.In order to prevent the carbon product oxidation of roasting, need pack the carbon product for the treatment of roasting in the metal saggar into, send into tunnel cave again, carry out after baking according to set heating curve.
Mainly there is following defective in the after baking device of this carbon product:
1. the not burning of part asphalt volatile constituents is arranged in roasting process, particularly do not have the asphalt volatile constituents of burning more in low temperate zone, the asphalt volatile constituents part that these are not burned enters in the atmosphere with tail gas, serious environment pollution, accumulate in after another part condensation on smoke exhaust pipe and the blower fan, must regularly clear up and to guarantee ordinary production.
2. tunnel kiln roasting furnace is a heating quirk control system, makes the interior temperature difference of stove bigger, and programming rate, finished product rate, product quality and hear rate are all had harmful effect.
3. tunnel kiln roasting furnace need be with more supporting machinery equipment, thereby investment is big.
4. tunnel cave formula after baking stove needs the saggar manufactured with a large amount of stainless steels or high nichrome, and this metal saggar oxidation consumption is big under the condition of high temperature, thereby the producing cost height.
In order to overcome the defective that existing carbon product after baking device exists, the utility model proposes ring type after baking stove and come the roasting carbon product.
The utility model is achieved in that this ring type after baking stove comprises combustion system, smoke evacuation system and body of heater, establishes a series of furnace chambers in body of heater.Combustion system, smoke evacuation system and some roastings and preheating furnace chamber are formed the roasting movement system.Combustion system is made up of burner and gas piping, and smoke evacuation system is made up of fume extractor and smoke discharging pipe.Be provided with several stove casees that quantity equates in each furnace chamber, each stove case is all by surrounding at the bottom of top light thermal-insulating lid, two sidewalls, two end walls and the stove case.All build by laying bricks or stones with refractory brick at the bottom of the wall of each stove case and the stove case, whole stove case will guarantee air tight.Be equipped with the heating quirk in four outsides of each stove case and bottom.The heating quirk is divided into two control systems, and promptly first that is made up of some corresponding stove case sidepieces heating quirks independently heats the quirk control system and reach and heat second that quirk forms by some corresponding stove case ends and bottom and independently add thermal bake-out quirk control system.Two heating quirk control systems are independent separately, not connected, stove case sidepiece heating quirk is that two sidewalls by adjacent stove case constitute, the sidepiece heating quirk of the corresponding stove case of the adjacent furnace chamber in front and back is interconnected, heating quirk in stove case end is that two end walls by adjacent stove case constitute, and the end quirk of the adjacent stove case in front and back is interconnected.End heating quirk and bottom heating quirk also are interconnected.First heating quirk control system mainly is that according to the rules heating curve adds thermal bake-out, and second heating quirk control system mainly is to make furnace temperature be tending towards homogenizing and carry out heat regulation control in order to eliminate in the stove case upper and lower temperature difference.Each quirk is communicated with and places movably flashboard in place's exhaust opening between the cooling furnace chamber outside first heated oven chamber in movement system and the system, last preheating furnace chamber and system to be entered outside the system carry out between the furnace chamber of preheating each quirk and are communicated with and also place movably flashboard in place's exhaust opening in movement system, and each flue is opened with the flue partition before and after the system.Between the adjacent stove case in front and back continuous passage is set, this passage is the passage that flows to high temperature quirk district as each stove case volatile matter.Gate all is set in this passage, is used for controlling its connection or partition.Each stove case epicoele all is provided with a linkage path that is connected with the heating quirk.This passage is a passage of asphalt volatile constituents in the stove case being introduced the quirk internal combustion, and a gate is set in this passage, is used for controlling this passage UNICOM or partition.In the roasting movement system, have only this passage of heating maximum temperature stove case just to allow to open, this passage of other stove casees all is closed, so that make the asphalt volatile constituents that each stove case produces in the movement system can only introduce burning in the highest temperature quirk.
Without the metal saggar, directly the carbon product of wanting roasting is packed in the stove case, do not add any inserts in the stove case, cover insulation cover.The burner of first and second heating control system movably is displaced on the furnace chamber that adds thermal bake-out, and each burns to chew and inserts corresponding quirk and burn and chew in the inlet to make burner, and burner is connected with gas piping outside the stove.Last each quirk exhaust opening of preheating furnace chamber tail end is connected with each arm of fume extractor movably, and fume extractor is connected with the outer smoke exhaust pipe road of stove, each furnace chamber quirk exhaust opening is all covered completely in the roasting movement system.The gate of asphalt volatile constituents flow channel is closed tight between first heated oven chamber and cooling furnace chamber, last preheating furnace chamber and the gate of waiting to enter the asphalt volatile constituents flow channel between the preheating furnace chamber are also closed tight, and the asphalt volatile constituents flow channel gate between intrasystem each furnace chamber all is opened.The heated oven chamber that has only the highest temperature just allows to open the linkage path gate between stove case epicoele and quirk, and this gate of each stove case of other furnace chambers all is being closed.In the heating roasting process, adds each the stove case of heated oven chamber in thermal bake-out movement system with giving gas outward, and the stove case of each furnace chamber of its back of preheating successively.Around the stove case and bottom is heated or by preheating successively, the asphalt volatile constituents that each stove case constantly produces is full of stove case space, is protecting roasted product not oxidized.Like this, the asphalt volatile constituents that produces in each stove case in the system can only flow and is hedged off from the outer world out to high temperate zone by flow channel.Because all being sucked in the highest temperature quirk from the linkage path between each stove case epicoele of the highest temperature and the quirk, burns the asphalt volatile constituents that each stove case produces in the quirk suction, roasting movement system.Tail gas then discharges out of the furnace by smoke evacuation system.When the carbon product temperature reaches 650～700 ℃ in the heating furnace case, this roasting furnace chamber withdraws from and adds the thermal bake-out movement system and become the cooling furnace chamber, corresponding mobile backward furnace chamber such as burner, fume extractor and flue shutter, inferior high temperature furnace chamber becomes heating highest temperature furnace chamber, this furnace chamber and just withdrawed from asphalt volatile constituents flow channel closing gate between the furnace chamber of roasting system, the linkage path between each stove case epicoele of new highest temperature furnace chamber and the quirk is opened.Treat that near of movement system the preheating furnace chamber includes preheating in the system in, and the asphalt volatile constituents flow channel gate between its each stove case and the former movement system opened, with the linkage path closing gate between its each stove case epicoele and the quirk, so just form a new roasting movement system, circulation promptly realizes the purpose of this utility model and so forth.
Gate between gate in the utility model on the used asphalt volatile constituents flow channel and stove case epicoele and the quirk on the linkage path can be made with heat-resisting cast iron, also available refractory material is made, and its action implements can be automatically, also can be manual according to technological requirement.
Than the utility model following advantage is arranged with the traditional secondary calciner:
1. the pollution of asphalt volatile constituents to environment thoroughly effected a radical cure in the asphalt volatile constituents that produces in roasting process completing combustion in the highest temperature quirk in stove;
2. operating cost is low, and is not oxidized with asphalt volatile constituents protection baked article in the roasting process, therefore no longer needs expensive metal saggar and inserts, just can realize low temperature funiclar curve roasting technique, and only this can make production cost reduce 15-20%;
