Abstract
An energy-saving and environment protection type process for preparing charcoal from tree wood or other raw materials includes such steps as heating in the condition of isolating air for dry distillation and charring, cooling, using afterheat to preheat raw material, using hot tail gas to dry raw material and recovering by-product generated by dry distillation.
Description
Affiliated technical field
The present invention relates to a kind of energy-saving and environmental protection charring process method of firing charcoal, belong to destructive distillation, charring process field.
Background technology
Charcoal is the bigger a kind of product of amount ratio in people's daily life and the industrial production.Charcoal is generally trees and forms through charing.At present, producing charcoal, to adopt comparison primary earth kiln and traditional technology substantially be main.When firing charcoal, in kiln, place trees or other raw material, seal wicket then, light a fire at lighting-up tuyere, a part of trees or other raw material are lighted, with the lighting-up tuyere sealing, utilize blast inlet control air quantity, when reaching certain temperature in the kiln then, the enclosed ventilation mouth, the smoke outlet sealing, trees or other raw material that the kiln internal combustion are flame-out, make charcoal.Produce charcoal with earth kiln and traditional technology, processes such as its intensification, dehydration, charing, cooling are all carried out in kiln successively, and the production cycle is long, and wastes a large amount of energy.The kiln temperature skewness, the charcoal quality is also inhomogeneous.Obnoxious flavour contained in the tail gas directly enters atmosphere, serious environment pollution.
Summary of the invention
The charcoal producing and manufacturing technique that the purpose of this invention is to provide a kind of energy-saving and environmental protection.Adopt trees or other raw material with the isolated condition of air under heat, carry out dry distillation charring, stove cools off outward, utilize refrigerative waste heat preheating material, the heat that utilization adds the tail gas of thermogenesis carries out drying to raw material, and reclaims the energy-saving and environmental protection charcoal producing and manufacturing technique of technical measures such as pyrogenous byproduct.To overcome the deficiencies in the prior art.
The technical solution adopted for the present invention to solve the technical problems is: charing institute heat requirement is supplied with by combustion outer Indoor Combustion coal or other solid fuel earlier.Trees or other raw material are isolated with air in coking chamber, after reaching certain temperature, both produced coal gas and other inflammable gas, coal gas enters inner combustion chamber's burning by coking chamber through production well, air then enters the combustion chamber by the ventilation hole of inner combustion chamber top, mixes with coal gas and burns.Flame heats up coking chamber by quirk, and cigarette then enters chimney by flue and discharges.The coking chamber gauge is less, can make trees or other raw material heat-up rate in the coking chamber fast, is heated evenly.Utilize the waste heat of heating and cooling that trees or other raw material are carried out preheating and drying simultaneously.Reach the purpose of energy-saving and environmental protection.
The invention has the beneficial effects as follows that owing to adopt and the isolated heating of air, kiln cools off, and makes full use of waste heat, reclaims the destructive distillation byproduct outward.Thereby the charcoal quality is good; Save energy, with short production cycle; Advantages such as environmental pollution is little.
Description of drawings
Below in conjunction with drawings and Examples the present invention is done detailed explanation.
Accompanying drawing is a process flow sheet of the present invention.
Embodiment:
Technological process of the present invention be trees or other raw material with the isolated condition of air under heat, carry out dry distillation charring, carry out under the outer refrigerative condition of stove, the many coking chambers of the major equipment that is adopted, external combustion type charring furnace are applied for utility model patent separately.
At first will put into coking chamber, build bell through preheating pack into trees or other raw material of casher box.Elder generation's combustion outer chamber firing up, when the coking chamber temperature reaches 300～500 ℃, coal gas and other inflammable gas had both been produced, open ventilation hole this moment, the air admission inner combustion chamber mixes with coal gas and burns that coking chamber is heated up, and cigarette then enters the drying machine drying raw material by flue, reclaim the destructive distillation byproduct through retrieving arrangement then, discharge by chimney at last.Simultaneously, exterior combustion chamber cease combustion, and sealing.When reaching 500～900 ℃ in the coking chamber, bell after 1～8 hour, is opened in the enclosed ventilation hole, and the charcoal that bakes is put into cooling tank, cools off putting into cooling kiln.To pack into the simultaneously trees of casher box or other raw material carries out preheating putting into cooling kiln.Carry out the production of next round then.When the charcoal that bakes is cooled to below 30 ℃, can pack.
