Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1 to 4, an environment-friendly biochar production device comprises a biomass pyrolysis chamber 10, a feeding mechanism 20, a biochar collecting chamber 30 and a combustion supporting device 40, wherein the biomass pyrolysis chamber 10 is used for thermally cracking biomass, a chain grate 11 is arranged at the bottom of the biomass pyrolysis chamber 10, and a discharge port 12 is unidirectionally arranged at one end of the biomass pyrolysis chamber 10, which is used for discharging the chain grate 11; the feeding mechanism 20 is connected to the upper part of the biomass pyrolysis chamber 10, and the feeding mechanism 20 can convey biomass to the biomass pyrolysis chamber 10; the biochar collecting chamber 30 is arranged below the biomass pyrolysis chamber 10 and is communicated with the discharge port 12; the output end of the combustion supporting device 40 is arranged on an area close to the input end of the chain grate 11, one input end of the combustion supporting device 40 is communicated with the top of the biomass pyrolysis chamber 10, and the other input end of the combustion supporting device 40 is connected with the outside.
In the above embodiment, in order to avoid tempering, the discharge port 12 is provided with a unidirectional baffle 14. The design can effectively prevent a great amount of combustible gas in the biomass pyrolysis chamber 10 from entering the biochar collecting chamber 30 to cause tempering, and meanwhile, the unidirectional baffle 14 can also simply separate the biomass pyrolysis chamber 10 and the biochar collecting chamber 30, so that the mutual influence is reduced.
Referring further to fig. 1 to 3, in order to realize feeding, the feeding mechanism 20 includes a hopper 21, a conveying cylinder 22, and a feeding auger 23 disposed in the conveying cylinder 22, one end of the conveying cylinder 22 is connected to the upper portion of the biomass pyrolysis chamber 10, the other end is connected to the output end of the hopper 21, and one end of the feeding auger 23 extends out of the conveying cylinder 22 and is connected to a driving motor 24. Wherein the transfer drum 22 is disposed obliquely upward and the hopper 21 is located at the lower end of the transfer drum 22. Of course, in some embodiments, the delivery cartridge 22 may be disposed horizontally, which is designed according to the needs, with the present utility model being preferably disposed horizontally.
The biomass pyrolysis chamber 10 needs to be ignited manually in the early stage of operation, and can also be ignited remotely through the combustion supporting device 40, at this time, the combustion supporting device 40 can adopt the same structure as a conventional gas burner, at this time, gas can be introduced from the outside to ignite, and after biomass in the biomass pyrolysis chamber 10 is automatically combusted, the generated high-temperature pyrolysis gas can be accumulated at the top of the biomass pyrolysis chamber 10. In addition, as the temperature of the high-temperature pyrolysis gas can reach more than 200 ℃, the high-temperature pyrolysis gas can also dry biomass fuel in the top of the biomass pyrolysis chamber 10 to be changed into dry materials, so that the high temperature in the biomass pyrolysis chamber 10 can directly crack the dry materials into combustible gas. Since biomass fuels are typically vegetable fibersAnd so on, wherein when the biomass fuels move into the biomass pyrolysis chamber 10 from the feeding mechanism 20, volatile matters in the biomass are greatly separated out under the action of high temperature, the action temperature is about 500-600 ℃, and after the volatile matters are separated out, the biomass only remains residual charcoal, wherein the volatile matters separated out by the thermal decomposition reaction mainly comprise hydrogen, carbon monoxide, carbon dioxide, methane, tar, other hydrocarbon and the like, and the main gasification pyrolysis principle and conditions of the dry materials are as follows: C+O 2 ＝CO 2 、CO 2 +c=2co, etc.; wherein the combustion-supporting device 40 supplies insufficient air simultaneously with the pyrolysis gas so that the biomass material can be burned into CO 2 However, the biomass fuel is continuously combusted in the biomass pyrolysis chamber 10 so that the internal temperature thereof can reach more than 500 ℃, thus CO 2 Can react with the carbon remained by the combustion in the biomass in an endothermic way to produce carbon monoxide, and the carbon monoxide mainly enters the biomass pyrolysis chamber 10 through the combustion supporting device 40 for combustion. Therefore, the whole process realizes a gas cycle, and the whole production equipment automatically and continuously produces in the later period.
Further, in some embodiments, in order to enable cyclic production, the combustion-supporting device 40 includes a suction pipe 41, a burner 42, and a suction pump 43 disposed on the suction pipe 41; one end of the suction pipeline 41 is communicated with the top of the biomass pyrolysis chamber 10, and the other end is communicated with the furnace end 42; the furnace end 42 is arranged at one side or below the chain grate 11, and the input end of the suction pump 43 is communicated with the outside through a one-way pipe 44. In fact, the unidirectional pipe 44 mainly serves to suck less air to regulate the concentration of the cracked gas in the suction line 41 and the ratio between the various components, so that the cracking and carbonization effect of the whole production plant is better. And the suction pump 43 mainly allows the pyrolysis gas accumulated on the top of the biomass pyrolysis chamber 10 to circulate into the furnace head 42, and then to be ignited and accelerate the combustion and carbonization process of the biomass above the chain grate 11. Wherein, in order to control the air intake conveniently, the unidirectional pipe 44 is provided with a control valve 47.
It should be noted that, when the biomass above the chain grate 11 burns to a certain extent, the biomass is sent into the discharge port 12, so that the biomass falls into the biochar collecting chamber 30, and the oxygen in the whole biomass pyrolysis chamber 10 is insufficient, so that the biomass cannot be fully burned and carbonized; the oxygen content in the area of the discharge hole 12 is smaller than that in the area of the chain grate 11 corresponding to the furnace end 42, so that the burnt biomass is gradually extinguished and charred and accelerated. After these biomass falls into the biochar collecting chamber 30, the area is substantially free of oxygen because a lot of biochar has accumulated in the area, and for this reason, the biomass at high temperature can only be carbonized in the area, and the carbonization effect is ensured to the greatest extent.
Further, in order to enable the biomass above the chain grate 11 to burn and break down rapidly, a mixing cavity 45 is provided in the furnace end 42, a plurality of gas nozzles 46 are provided on the furnace end 42, and the gas nozzles 46 are communicated with the mixing cavity 45. Wherein, the mixing cavity 45 can fully mix the pyrolysis gas and the air, so that the biomass is convenient for supporting combustion in the later period. It should be noted that, the unidirectional tube 44 is not always open, and is only opened according to the combustion condition in the biomass pyrolysis chamber 10, so that the combustion condition in the biomass pyrolysis chamber 10 can be effectively regulated, and the carbonization efficiency of the biomass pyrolysis chamber 10 is ensured to the greatest extent.
In one embodiment, in order to facilitate the collection of the pyrolysis gas in the biomass pyrolysis chamber 10, a gas collecting hopper 13 is disposed at the top of the biomass pyrolysis chamber 10, and the gas collecting hopper 13 is communicated with a corresponding end of the suction pipeline 41.
Referring to fig. 4, in order to maximize the utilization of heat generated in the biomass pyrolysis chamber 10, a high efficiency carbonization process is ensured. In some embodiments, the portion of the suction line 41 between the suction pump 43 and the top of the biomass pyrolysis chamber 10 is wrapped around the outer wall of the loading mechanism 20. The biomass in the feeding mechanism 20 can be heated and dried to a certain extent by the pyrolysis gas in the suction pipeline 41, and the later combustion carbonization effect is improved.
With further reference to FIG. 3, for rapid cooling within the biochar collection chamber 30Biochar, in a modified embodiment, a cold water spray 31 is provided within the biochar collection chamber 30. The cold water spraying device 31 may be a conventional water spraying device, for example, a spray pipe and a pump body, one end of the spray pipe is connected with an external water source, the pump body is installed on the spray pipe, and meanwhile, the spray pipe is wound on the inner wall of the biochar collecting chamber 30, so that the water body in the spray pipe can be heated through a heat exchange effect, and atomization is facilitated. It should be noted that the cold water spraying device 31 sprays and cools the high-temperature biochar, at the same time, the high-temperature steam reacts with the high-temperature biochar, and the steam is utilized to perform a reduction reaction with the high-temperature charcoal in the biochar collecting chamber 30, so that the conventional water drops or water flows can kill or excessively cool the high-temperature charcoal, which greatly affects the efficiency and quality of the whole reduction reaction, and therefore, the steam is utilized to react with the high-temperature charcoal in the utility model. The reaction principle is H 2 O+C＝CO+H 2 The process is an endothermic process, so that the high temperature carbons can be effectively cooled. At the moment, a large amount of combustible gas can be produced by producing carbon, so that the method can achieve two purposes. The gases can be discharged outwards through a suction system for collection and utilization, and can also be directly introduced into the furnace end 42 for combustion supporting.
With further reference to fig. 4, during actual use, since the biomass pyrolysis chamber 10 is continuously subjected to pyrolysis combustion, a large amount of heat is necessarily generated, and besides the heat supplied to the biomass pyrolysis chamber 10 for preheating biomass fuel and dissipated to the outside, the whole production equipment is necessarily subjected to continuous residual heat. The preheated biomass fuel always belongs to internal energy transmission, and except for heat carried by the produced biochar when the biochar is discharged outwards, the whole production process is basically and totally closed, and therefore, the whole production device is prevented from being overheated and the redundant heat is reasonably utilized. In a modified embodiment, in order to facilitate combustion supporting of the combustible gas generated in the process of cooling the biochar, a heat-conducting separation plate 50 is arranged between the biochar collecting chamber 30 and the biomass pyrolysis chamber 10, and a plurality of air passing holes 51 are formed in the heat-conducting separation plate 50. In order to facilitate the adjustment of the amount of the combustible gas, in a modified embodiment, an adjusting plate 52 is movably disposed in the heat-conducting separation plate 50, a plurality of through holes 53 matching with the gas passing holes 51 are disposed on the adjusting plate 52, and the adjusting plate 52 can move in the heat-conducting separation plate 50 to enable the gas passing holes 51 to be dislocated with the through holes 53. It should be noted that the adjusting plate 52 may be used in combination with the unidirectional baffle 14, so as to prevent the combustible gas in the biochar collecting chamber 30 from entering the biomass pyrolysis chamber 10 from the discharge port 12 and tempering. Due to the heat conducting partition plate 50, the biochar collecting chamber 30 can continuously obtain heat supplement, so that steam and high-temperature charcoal can react conveniently, the yield of hydrogen and carbon monoxide is greatly increased, and the combustible gases can be discharged outwards conveniently.
This environmental protection biochar production facility utilizes biomass pyrolysis room 10 to carry out thermal cracking living beings, and it utilizes chain grate 11 to carry out the delivery volume, can send into discharge gate 12 with the living beings of burning fast, and then falls into in the biochar collecting chamber 30, lacks sufficient oxygen in the biochar collecting chamber 30 at this moment for these burnt biochar are extinguished gradually and carbomorphism. The design of the chain grate 11 can realize continuous carbonization of biomass, and improves the production efficiency. And the combustion supporting device 40 is utilized to further carry out secondary reaction on the combustible gas and carbon dioxide generated in the biomass cracking chamber 10 in the cracking process and part of newly-entered air, so that heat can be continuously provided to promote the carbonization process of the biomass. And a large amount of waste gas is not discharged outwards in the whole carbonization process, and the normal operation of the whole biomass pyrolysis chamber 10 is maintained by adopting the heat of carbonization combustion of biomass, so that the energy consumption adopted in the production process is reduced. The biochar collecting chamber 30 can primarily cool the biochar such that internal sparks are extinguished, facilitating the later outward discharge while reducing the risk of afterburning after contact with air.
