Description

The moving-bed continuously carbonizing stove of Uniform Ventilation

[technical field]

But it is quantity-produced charring furnace raw material, vertical with bamboo and wood, husk, sawdust etc. that the utility model relates to a kind of.

[background technology]

CN1458225 and CN1629256 successively disclose Mr.'s Hu Fuchang " method of bamboo timber continuous carbonization charing " and " method and apparatus of internal combustion self-heating moving bed dry distillation charring " two patented technologies, the former is mainly used in bamboo charcoal and the charcoal of producing high charring degree, high absorbability, high conductivity, the latter be mainly used in produce refractive index 8% or more bamboo (wood) vinegar liquid and fixed carbon more than 85%, below resistance 10 Europe, iodine sorption value greater than high-quality bamboo (wood) charcoal of 500mg/g.These two inventions have its distinctive feature at energy-conservation, work efficiency, cost, high-quality aspects, and its favorable economic benefit and social benefit are arranged.The former is tubulation vertical type moving-bed for these two kinds of charring furnaces, upright and parallel to each other being distributed in the furnace chamber of many tubulations, bamboo (wood) sheet or its processing waste material are knocked down and are carried out charing in the tubulation, and the outer space of tubulation can not be as the part of moving-bed, and effectively the moving-bed capacity is little.The furnace chamber integral body of a kind of charring furnace in back is moving-bed, the raising of favourable work efficiency.But two kinds of stoves all can not be produced charcoal as raw material with the little husk of particle diameter, sawdust, and on the current market low-grade charcoal are had big demand, as make mosquito-repellent incense filler etc., adopt aforementioned two stoves favourable, improve its incompatibility face, and do not have and be suspected to have its realistic meaning.

[utility model content]

Fire low-grade charcoal at prior art is incompatible with small particle size raw materials such as husk, sawdust, to satisfy the deficiency of relative users demand, the purpose of this utility model is to design a kind of high-grade bamboo charcoal of both can having fired, and again can small particle size biological material is fired the moving-bed continuously carbonizing stove of the Uniform Ventilation of low-grade charcoal as raw material.

Above-mentioned purpose can be realized by following measure: the moving-bed continuously carbonizing stove of this Uniform Ventilation, include charging opening, air outlet, body of heater, blast inlet, the air channel, cooling tube, discharge port, charging opening and discharge port have the sealing member that can open and close as required, the body of heater tubular, furnace chamber is divided into drying zone by function from top to bottom, pre-char zone, the calcining char zone, the furnace chamber central part has the ventilation core pipe of the core close with the furnace chamber height every post and its underpart, equidistantly distributed blast inlet on the circumference of furnace wall, body of heater middle and lower part, and equidistantly distributed the air channel on the core pipe circumference of this blast inlet level attitude and between the stove inwall circumference, have the wind hole on the air channel, core pipe and core are every column outer wall, the air channel, the stove inwall laterally is divided into class trapezoid area near the interval that equates with the furnace chamber space, and each interval is distributed with above-mentioned ventilation plant equably.

Above-mentioned purpose is also come perfect by following measure: core pipe, air channel, stove inwall laterally are divided at least three class trapezoid intervals with the furnace chamber space; Said sealing member is the water-lute parts at charging opening, and discharge port is to cover the formula sealing member; Wind hole on the said air channel is downwards or to the lower side opening.

The beneficial effects of the utility model are that ventilation opening is evenly distributed, and favourable charing is even, the air channel downside with below be furnished with the wind hole and stop small particle size charcoal or raw material plug-hole, suitable husk, sawdust are made the charing raw material, the selection face of raw material enlarges, and the high and low shift charcoal all can be fired, and satisfies the needs of different user.Do not establish tubulation, enlarged the capacity of moving-bed, the work efficiency height.

Fig. 2 is the A-A sectional view of Fig. 1.

[embodiment]

The utility model is described in detail below in conjunction with embodiment and with reference to accompanying drawing: body of heater 5 is in pre-char zone, calcining char zone position is made by lagging material and refractory materials, air outlet 1, air channel 12, cooling tube 11, charging opening 3, discharge port 10 usefulness stainless steels are made, fire bamboo charcoal, the blast inlet 6 of charcoal, air channel 12 distributes and dredges, fire the husk charcoal, the distribution of wood chip powdered carbon is closeer, it is the setting in the air channel 12 in the radial distribution at center and the hole 13 of blowing in that ventilation core pipe 7 reaches with it, help evenly ventilating between each step sector of furnace chamber 14, this is to adapt to husk, sawdust is the needs of raw material charcoal processing.Charging opening 3 can adopt manhole cover 2,9 sealings of discharge port 10 usefulness sealing covers.Core plays the recessive furnace chamber of separating every the air channel 12 that post 4 and an end are fixed on it.

Add the homogeneity bamboo charcoal to slightly super air port 6 height from charging opening 3 earlier when burning bamboo charcoal, combustion preheater furnace chamber 14, heat up, add charcoal one by one extremely near charging opening 3 about half meter, when calcining char zone temperature reaches 500-600 ℃, be the bamboo section about 30cm toward furnace chamber 14 interior lengthenings, the bamboo processing clout that bamboo chip or big or small thickness do not wait, go out charcoal one time through 2h approximately, added one time the bamboo material every 1.5-1.8 hour, the ventilation of controlling well during this time reaches the purpose of controlled temperature, the control ventilation can be by the vacuum fan on the air outlet 1, blast inlet 6,8 regulate the air port size realizes, general requirement is burnt 900 ℃ of bamboo charcoal calcining char zone temperature, calcines 650-700 ℃ of char zone temperature when bamboo vinegar liquid is the major objective product and make.

Make charcoal with husk and sawdust, roughly method is the same, need turn down ventilation, and the calcining char zone temperature of husk is controlled at 400-500 ℃, 600-700 ℃ of sawdust temperature control.

Burn the air channel 12 usefulness stainless steel tubes of husk, sawdust and make, double walled should be used in the air channel 12 of burning bamboo charcoal, in order to avoid bamboo chip, bamboo charcoal are put.
