Description

The plain can-type calcine furnace of a kind of novel charcoal

Technical field

The utility model belongs to the technical field of carbon product, is specifically related to a kind of raw petroleum coke calcining main equipment---the technology reforming scheme of the plain pot furnace of charcoal.

Background technology

At present, main pot furnace and two kinds of equipment of rotary kiln of adopting of carbon product enterprise raw petroleum coke calcining.Pot furnace is compared with rotary kiln, and its major advantage is: quality product is high and stable; The carbonaceous scaling loss is few: do not add or few refuel: converter life long (in general eight to ten years can not overhaul) etc.Yet it also exists output on the low side; Heat-energy losses is excessive; Shortcomings such as operational condition difference.

In the last few years, pot furnace some improvement had been made.As: material chamber height and quirk height strengthen simultaneously, and the quirk number of plies is increased to eight layers by six layers; Cancellation lattice formula special-purpose air primary heater unit; High-temp waste gas is drawn body of heater and is added to utilize; Bottom of furnace body is newly established the preheated air road; Strengthen the watercooling jacket size and strengthen material cooling performance etc.Through after the above-mentioned improvement, pot furnace is by the still formula refinery coke of original production volatile content 6～7%, and output is 50～60kg/h jar; Can produce the retard petroleum coke of volatile content 10～15% till now, output can reach 85kg/h jar (contain 15～20% and return batching).But still there are many shortcomings in the pot furnace after improving, mainly contains: (1) material transverse section, chamber and quirk cross-sectional dimension and structure do not become, and output is on the low side, can not adapt to the needs of the plain enterprise of large-scale charcoal; (2) furnace bottom preheating of air efficient is not high little to material chamber cooling performance; (3) design of fugitive constituent road is unreasonable, makes unnecessary fugitive constituent also in the body of heater internal combustion, has caused the long dump temperature of calcining zone too high, and wasted heat energy: (4) furnace insulation poor performance causes stove table temperature too high; (5) the original design burner structure that remains with because of not needing extra fuel, does not have actual use value.

The utility model content

Domestic and international aluminium industrial equipments maximizes and the requirement of energy-saving and environmental protection in order to satisfy, at the existing problem of the plain can-type calcine furnace of above-mentioned charcoal, the design people is summing up on the basis of production experience for many years, and use for reference the technology of metallurgical coke oven and ring type carbon roasting furnace, the plain can-type calcine furnace of a kind of novel charcoal has been proposed.

The utility model proposes the plain can-type calcine furnace of a kind of novel charcoal, comprise reinforced hopper, material chamber, quirk, flue, fugitive constituent road, preheated air road and support frame, it is characterized in that:

(1) set up special-purpose fugitive constituent road, and added and be equipped with adjusting control valve;

(2) the quirk number is reduced half, and increased the width and the height of quirk;

(3) furnace bottom preheated air road is divided into four layers, last layer is communicated with special-purpose fugitive constituent road, below three layers be the preheated air road;

(4) removed the fuel nozzle of front wall, and the baker burner has been set at the back wall.

The plain can-type calcine furnace of existing charcoal all inserts the heating quirk with fugitive constituent, makes fugitive constituent all in the quirk internal combustion.And from heat calculation as can be known, the raw petroleum coke volatile content only needs 5～6%, and the heat energy that it produced can satisfy the needs of can-type calcine furnace ordinary production; And at present the volatile content of carbon element enterprise calcined petroleum coke allows fugitive constituent perfect combustion in quirk all about 10～15%, and being actually has wasted 30～50% fugitive constituent (calorific value 3300kcal/Nm ³).So in present design, other has designed the special-purpose fugitive constituent road with valve control, adjusting, and unnecessary fugitive constituent is directed to the body of heater main flue, make the residue fugitive constituent in the proper site burning of setting, heat energy obtains fully, reasonable use thereby make.Simultaneously, because the design's residue fugitive constituent does not burn, just prevented that also material chamber calcining zone from moving down with dump temperature too high in the quirk below four layers.

Second technical characterictic of the present utility model is the structure of having improved the preheated air road, changes furnace bottom preheated air road individual layer useful area into 308 millimeters * 400 millimeters * 2 by existing 236 millimeters * 210 millimeters, increases to four layers by original two-layer.Last layer is walked to remain fugitive constituent and it is caused in the outer main flue of body of heater to burn, at Lu Houqiang a gas blower is set, air is introduced in the basecoat preheated air road, made it successively by two, three layers of preheated air road, the high temperature air after the preheating is drawn the outer use rationally of stove.The preheated air road is arranged on the both sides of material chamber, and air is in the process of preheating, and it can play cooling effect to the material chamber simultaneously, thereby has also reduced dump temperature.

All there is quirk its both sides, material chamber of the plain can-type calcine furnace of existing charcoal, and also are provided with partition wall between the quirk of adjacent two material chambers.In the present design, the partition wall between adjacent two quirks is removed, made the quirk number reduce half, make every group of material chamber become shared one group of quirk by two groups of quirks of original use, and the corresponding width that has increased material chamber and quirk.The utility model will have the material chamber now and be widened to 500 millimeters from 360 millimeters, and material chamber height also suitably increases, and make material chamber volume increase about 50%; Simultaneously again the quirk number of plies is increased to nine layers by eight layers, to increase the time that material stops in the material chamber, these aggregate measures can make pot furnace output improve 50% or higher.

The heat that burning is produced in view of the raw petroleum coke fugitive constituent is enough to keep the ordinary production of calcining furnace, does not need extra fuel again, and the utility model is cancelled the former fuel nozzle device that is arranged on the calcining furnace front wall, and baker is displaced to the back wall with simple and easy burner.In addition, 1800 millimeters of the outstanding bodies of heater of intrinsic main flue, and the design moves after main flue is in body of heater now, has reduced the total width of body of heater.At last, the design has also suitably increased around the body of heater and the thickness of end face thermal insulation layer, to strengthen the heat insulation effect of body of heater, like this, both can improve the labor condition in workshop; Can reduce dissipation of heat energy, save energy again.

In a word, the plain can-type calcine furnace of novel charcoal of the present utility model possesses following advantage:

(1) improved single jar output, furnace binding is rationally compact, and the initial cost of unit output reduces, and calcining furnace efficient is improved, and can realize the maximization of calcining furnace;

(2) owing to unnecessary fugitive constituent in the raw material obtains fully, reasonably utilizes, add the reasonable setting in preheated air road, can save energy.
