Description
Technical field
The present invention relates to bamboo charcoal and produce equipment, the particularly energy saving kiln of a kind of high efficiency production bamboo charcoal.
Background technology
Bamboo charcoal is the solid product that bamboo wood obtains under the hot conditions of anaerobic or few oxygen after super-dry, carbonization process thermal decomposition, and it has special absorbability and bigger specific surface area, and bamboo charcoal tool has been widely used, and can be used as fuel, warms oneself for family; Formaldehyde can be absorbed in interior decoration, also can craft articles. Many rings after bamboo processing, bamboo point, bamboo powder are all the good raw materials making bamboo charcoal, but bamboo charcoal is prepared in forest zone at present is the production utilizing single earth kiln one basket a basket, yield poorly, the production cycle long, the heat utilization rate of earth kiln is low, need to consume substantial amounts of timber and coal, the quality produced also is difficult to ensure that, productivity is often below 20%.
Summary of the invention
The present invention is directed to the deficiency of existing earth kiln production technology, it is proposed to the energy saving kiln of a kind of high efficiency production bamboo charcoal.
The energy saving kiln of this high efficiency production bamboo charcoal, including a horizontal rotary stove, it is characterized in that, horizontal rotary stove bottom combuster, horizontal rotary stove outer layer is smoke chamber, chimney is arranged at smoke chamber top, in the middle part of horizontal rotary stove, one end is feed inlet and outlet, the other end is provided with exhaust column, air exhauster is installed in exhaust column, exhaust column has two arms, one is non-Gas Pipe, with atmosphere, non-Gas Pipe is provided with non-combustible gas solenoid, another is Gas Pipe, Gas Pipe has filtration liquid material cup, Gas Pipe has again two arms, one combustor arm communicates with combustor, another boiler arm communicates with the burner hearth of boiler, the smoke exhaust pipe of boiler communicates with bamboo charcoal drying room, the chimney of top of combustion chamber also communicates with bamboo charcoal drying room, combustor arm and boiler arm are provided with combustor arm electromagnetic valve and boiler arm electromagnetic valve.
Temperature sensor and humidity sensor it is provided with in horizontal rotary stove, temperature sensor and humidity sensor are by controller and combustor arm electromagnetic valve, boiler arm electromagnetic valve, non-combustible gas solenoid electrically connects, controller also electrically connects with air exhauster, by regulating non-combustible gas solenoid, combustor arm electromagnetic valve, boiler arm electromagnetic valve and air exhauster, temperature when initial stage in horizontal rotary stove is dried heating is maintained between 150-300 ° of C, temperature when later stage carbonization being heated is maintained between 300-500 ° of C and in order to regulate the flow drawing fuel gas in horizontal rotary stove.
During production, by feed inlet and outlet, the raw material of bamboo charcoal being loaded horizontal rotary stove, then passes through the combustion gas being externally introduced and light combustor, heated by horizontal rotary stove, and make horizontal rotary stove rotate, carbonization process generally can be divided into three below temperature section:
One, drying stage: the gas ignition head igniting of horizontal rotary stove inner combustion chamber, the combustor arm electromagnetic valve of horizontal rotary stove, boiler arm closed electromagnetic valve, the air exhauster of horizontal rotary stove leaves greatly, horizontal rotary furnace gas rises to 160 DEG C, at this moment the moisture contained by bamboo charcoal raw material relies primarily on additional heat and is evaporated, and the chemical composition of bamboo charcoal raw material does not almost become;
Two, the carbonization starting stage: this stage produces heat mainly by the burning of bamboo charcoal raw material self, makes horizontal rotary furnace temperature rise between 160～300 DEG C. Now, bamboo charcoal raw material generation pyrolysis, its composition starts to there occurs change, wherein unstable composition, and decomposing such as hemicellulose generates methanol, methane, CO and a small amount of acetic acid, CO2Deng material;
Three, comprehensive carbonization rank: the gas ignition head of combustor is closed, the combustor arm electromagnetic valve of horizontal rotary stove and air exhauster are opened, combustor relies on the fuel gas that in air exhauster extraction horizontal rotary stove, bamboo wood dry distilling produces to burn, the temperature in this stage is 300～500 DEG C, wood materials thermally decomposes sharp, has been simultaneously generated the product liquids such as substantial amounts of acetic acid, methanol and wood tar. Additionally creating the imflammable gas such as methanol, methane, wood materials at high temperature dry distilling becomes charcoal.
Four, carbonization ending phase: when wood materials thermal decomposition is complete, temperature declines, and imflammable gas is discharged seldom, then close air exhauster, bamboo charcoal product is taken out from horizontal rotary stove.
The present invention takes full advantage of the fuel gas of horizontal rotary stove dry distilling generation and again burns on the one hand, send into boiler on the other hand and produce steam, the flue gas of boiler and combustor enters drying room and utilizes, greatly save the energy, horizontal rotary stove makes bamboo charcoal heating raw materials uniform, improve production capacity, be ensure that the quality of product by controller and sensor, alleviate the labor intensity of operator.
