Description
Technical field
The present invention relates to a kind of carbonizing method and device, particularly relate to method and the device of a kind of making charcoal in array kilns and extraction flue gas.
Background technology
The process of firing charcoal is, timber or wood material are placed in charcoal kiln, and the timber in charcoal kiln or wood material are heated, the charcoal that obtains after making timber or wood material through pyrolysis under unburnt condition.
At present, charcoal kiln used all belongs to single klining mode processed, after soon timber or wood material are placed in charcoal kiln, be fired at last the finished product charcoal from beginning to be preheating to, and last process of cooling is completed in a charcoal kiln all.Existing carbonizing method is large in the loss of temperature-rise period Raw, and char yield rate is low.The flue gas that each of existing carbonizing method charcoal processing process produces in stage mixes, and is not easy to the flue gas that the charcoal processing process the produces extraction of classifying.
Summary of the invention
The object of the invention is to, method and the device of a kind of making charcoal in array kilns and extraction flue gas is provided.Material loss is few, and char yield rate is high.Be convenient to the flue gas that the charcoal processing process the produces extraction of classifying.
Technical scheme of the present invention: a kind of method of making charcoal in array kilns and extraction flue gas, the method is to produce the difference of smoke components according to charcoal processing process differing temps section, arrange with the corresponding charcoal kiln of different smoke components and consist of the charcoal kiln group, must the finished product charcoal after raw material is sent into successively each charcoal kiln and fired; Between two charcoal kilns, cave dwelling is set, extracts the flue gas of heterogeneity by cave dwelling.
In the method for the charcoal processing of aforementioned array kiln and extraction flue gas, but described different smoke components comprises flue gas and the burning fume of extractable matter.
In the method for the charcoal processing of aforementioned array kiln and extraction flue gas, but the flue gas of described extractable matter and burning fume are distinguished corresponding charcoal kiln at least.
According to the charcoal processing of aforementioned array kiln with extract the device that the flue gas method builds, comprise the charcoal kiln group that two or more charcoal kilns consist of, two charcoal kiln groups arrange back-to-back and consist of charcoal kiln group pair, are provided with cave dwelling between the charcoal kiln that charcoal kiln group centering arranges back-to-back.
In aforementioned means, be provided with the flue gas extraction element in described cave dwelling.
In aforementioned means, described flue gas extraction element comprises material extraction element and gas extracting device.
In aforementioned means, described material extraction element is connected with the charcoal kiln that a generation contains the extract flue gas at least; Gas extracting device is connected with a charcoal kiln that produces the inflammable gas flue gas at least.
In aforementioned means, the charcoal kiln in described charcoal kiln group is arranged vertically or horizontal.
In aforementioned means, be provided with heat-energy utilizing device in described cave dwelling.
Compared with prior art, because the present invention produces the difference of smoke components according to charcoal processing process differing temps section, the charcoal kiln corresponding from different smoke components is set, extract the different flue gas of composition from corresponding charcoal kiln, so the convenient flue gas that extracts different purposes from charcoal processing process differing temps section therefrom refines wood vinegar, wood tar oil, biofuel, pitch and other industrial chemicals etc.Also inflammable gas be can extract from flue gas, fuel gas generation or productive life supply combustion gas are.Also can draw from charcoal kiln High Temperature Gas after heat exchange for the production of or life power supply.The flue gas purity that the present invention extracts is good, and can simplify extraction equipment.
The initial purpose of method of the present invention is extracted problem in order to solve above-mentioned flue gas, but in use finds, warm-up time and process owing to having shortened between each stage can also shorten the firing time, reduce material loss, improves char yield rate more than 30%.Obtained beyond thought beneficial effect.
Because prior art is to complete whole sintering procedure in a charcoal kiln, and the present invention completes whole sintering procedure by a plurality of charcoal kilns successively, so if the present invention's planar alignment floor space is inevitable large than prior art, in order to address this problem, when Specific construction, each charcoal kiln that consists of the charcoal kiln group is arranged vertically successively from top to bottom by the mode that kiln increases progressively by temperature.The kilneye of two charcoal kiln groups arranged vertically consists of charcoal kiln group pair outwardly back-to-back; Between two charcoal kilns, cave dwelling is set, extracts the flue gas of heterogeneity by cave dwelling.Again plural charcoal kiln group is consisted of the charcoal kiln battle array to arrangement arranged side by side, can not enlarge floor space like this.When solving floor space, obtained again the beyond thought beneficial effect that improves the quality of products, analyze the reason that quality improves, be because in prior art, the temperature in kiln is that the bottom is lower than top, after adopting the present invention, at the bottom of the high temperature of lower floor's kiln can push up by the kiln of this layer and conduct to the kiln on upper strata, can make the temperature up and down in the kiln of upper strata be tending towards uniform and stable, the charcoal quality conformance that burns out is good, can improve the quality of products.
The present invention can also arrange the flue gas extraction element in cave dwelling, owing to adopting the cave dwelling structure, the flue gas extraction element is arranged in cave dwelling, can conveniently install.Also heat exchanger tube can be set in cave dwelling, the entrance of heat exchanger tube is connected with cold pipe, cold Guan Zhongtong cold water or cold oil, and the outlet of heat exchanger tube is connected with heating tube, is convenient to the heat recuperation recycling, also can accelerate speed of cooling simultaneously, shortens cooling time.And prior art so heat exchanger tube can not be set in the kiln wall of prior art, is not easy to the heat recuperation recycling owing to being to complete whole sintering procedures in a kiln, and cooling time is also longer simultaneously.Adopt method of the present invention except extracting wood vinegar, wood tar oil and combustion gas from the flue gas of charcoal processing, can also extract the industrial chemicals such as cold oil spout, wooden dephasign carbolic oil, biofuel, reodorant and sanitising agent from charcoal-making fume.Also can reduce pollution, improve Working environment, be conducive to environment protection, reduce the labor force and consume.
