Therefore, it is important for the development of any form of renewable energy. Renewable energy sources are “green”, “green” and “environmental pollution”. Among them, raw materials are used to call the most suitable liquid fuels and chemicals. Biomass raw materials include various types of organic waste, such as: agricultural or forestry waste, kitchen waste, animal waste, waste tires, etc., which are also known as bio-oil. Further step into a high-value fuel, such as bio-diesel. This process technology for converting raw materials into raw oils not only converts waste into valuable energy, but also achieves the environmental benefits of energy recovery and reuse and the environmental impact of waste reduction. At present, the technology for converting raw materials can be roughly divided into the following: 1_bio/chemical conversion: if gasoline, gasoline, biogas are produced by processes such as fermentation, esterification, etc. Bio-gas) or biodiesel; or a method such as a biological strain to produce a fuel such as hydrogen or sterol. 2. Thermal conversion: If direct combustion (direct 201221635 combustion) ^ ^ ^ (Pyrolysis) ^ ^ ^ b (gasificati〇n); r formula, produce synthetic gas (syngas) or fuel. Among them, pyrolysis technology mainly refers to solid fuel raw materials or waste, which is directly made into liquid fuel by thermal pyr〇lySis. The procedure is also called liquefaction. If properly purified, the calorific value of the liquid fuel can be effectively improved. 'The rapid pyrolysis technology that is currently developing is fast heating the raw material or waste forming gas under high temperature and anoxic conditions. Solid coke, the gas produced is quickly condensed to obtain a raw oil; in addition, the obtained solid coke is further processed to obtain a high value-added chemical. The main operating temperature for rapid pyrolysis is slightly higher than the traditional pyrolysis method 'about 450. 〇 to 6〇〇. Between 〇, the stagnation time is less than 1 second. Due to rapid temperature rise and rapid cooling, secondary cracking can be avoided. Therefore, liquid production of about 6 〇 to 75 wt 〇 / 可 can be obtained. The advantages of using derivative fuels produced by pyrolysis technology are high calorific value and convenient storage. It can be used as an auxiliary fuel for steel furnaces or directly used in generators, in line with the environmental and economic benefits of waste recycling and clean production. The technology of raw material or waste pyrolysis to produce synthetic fuel is not fully commercialized at present, but rapid pyrolysis technology will be the future development trend. The rapid pyrolysis reactors developed abroad include a vortex reactor, an entrained flow reactor, a rotating cone reactor, a vacuum transported bed, and a circulation. A variety of circulating fluid beds and the like. At present, the rapid pyrolysis reaction system can produce 50 to 75 wt% of liquid biomass oil, 15 to 25 wt% of coke, and 10 to 20 wt% of non-condensable gas, but the rapid pyrolysis reaction equipment still has some disadvantages such as energy loss in 201221635. Large, expensive, difficult to expand equipment, heat carrier (sand) and raw materials need to be nitrogened for fluidization, heat carrier and coke (char) separation is not easy, feeding is prone to suspension, hanging material or condensation into a block Blocking and other issues.

The components of the present invention are used in the main components of the present invention. The grant is in the traditional • medium _ tube easy to form dn feed unstable gas for the company to stop the problem. #壁挂料, resulting in control inspection crack 12: Please refer to m contains: a drive m a test and ^ map, the Control drive lead screw 20 reverse one control (four) u = 12, a push-pull square 8 201221635 pull-type square lead screw 20 send In addition, the frequency converter is used as the controller 13 to control the rotation speed of the speed reducer motor; and the push-type square lead screw 20 can utilize two ceramic bearings and a heat-proof gasket to support, fix and transmit, and achieve heat insulation. The purpose of the push-type square lead screw 20 is that the self-developed high-temperature, anti-oxidation and low thermal expansion coefficient of the spheroidal ink per iron is beneficial to the transfer of the raw material during the south temperature pyrolysis of the raw material. And avoiding the problem of deformation to the warm surface. Pyrolysis reaction device 3: Please refer to Fig. 1 and Fig. 3, the pyrolysis reaction device 3 is composed of a plurality of burners 21, wherein the burner 21 The stainless steel pipe is bent into a circular shape, and the hole is drilled at every 90 degrees of the round pipe, and then the heating burner composed of the quick burner, the nozzle and the connecting pipe is assembled, and the advantages thereof are high temperature heating uniformity and heating rate. Rapid gas/solid separation device 4: The volatile gas generated by pyrolysis contains a small amount of char (char) and ash (ash). If not properly separated, it will often cause blockage of the pipeline system, and carbon in coke and ash will Generate secondary heat The current φ image affects the production of raw oil and increases the formation of non-condensable gas. The general separation method is to use a cyclone to blow the volatile gas into the drum 23 with a conical bottom in a tangential direction. The coke and the ash are thrown to the outer circumference, and are collided with the wall to be discharged from the outlet of the lower portion of the conical bottom of the drum 23, and the volatile gas is discharged from the open end of the gas output line 22 at the center of the drum 23, the gas of the cyclone The output line 22 is deep inside the cyclone to prevent coke and ash from entering the gas output line 22. Please refer to Figure 4. Catalyst deoxidizer 5: Dissociated volatile gas, then add catalyst on the line to synchronize The catalytic reaction of the raw oil is carried out, and the oxygen 201221635 in the volatile gas is removed to increase the calorific value of the raw oil, please refer to Fig. 4. Condensing unit 6: The volatile gas generated by pyrolysis will rapidly form liquid biomass oil and non-condensable gas under condensing conditions. However, the temperature and time of the volatile gas generated by pyrolysis to the condensation stage directly affect the yield and composition of the raw oil, because the volatile gas and the raw oil are liable to cause secondary pyrolysis under high temperature conditions. Therefore, the more non-condensed gas is generated, the production of bio-oil is greatly reduced. The condensing device 6 of the present invention can utilize liquid condensate to rapidly condense volatile gases, and the condensation temperature is controlled below 5 ° C to increase the yield of liquid biomass oil. Examples of Rapid Pyrolysis of Biomass Raw Materials The following further explains the steps and process parameters of the pyrolysis test of the raw material using the raw material of the present invention converted into a rapid pyrolysis equipment system for the raw oil. The raw materials are rapidly pyrolyzed into liquefied oils, and the selection of process parameters is the main key factor affecting their reaction efficiency and productivity. The most important factors causing low productivity of raw oil include: too high pyrolysis temperature, too slow heating rate, too long residence time of volatile gas, and too long condensation time, resulting in secondary pyrolysis of volatile gas. All are non-condensable gases. On the other hand, when the water content and the oxygen content in the raw oil component are too high, the calorific value, the burning point, and the compositional properties are unstable. 1. Particle size of raw material: In order to increase the heating rate and obtain higher productivity, the particle size of the raw material after pulverization is very important. When the particle size is less than 1 mm, the pyrolysis process belongs to the kinetic reaction mechanism; When the particle size is larger than 1 mm, the pyrolysis process belongs to heat transfer and mass transfer control, so the particle size is 201221635. When the heat reaction process of the sizzling reaction is repeated, the granules are more than a certain size. The range of volatile diffusion is slower, and when the gas phase product stays large, the interior is pyrolyzed into small molecules of helium. Because of the long term, more ginseng oil is used. Therefore, the example uses eucalyptus as the raw material 枓', and the granule parameter level is below l.Gmm. Low causes the It material to dry. When the water content of the raw oil is too high, the calorific value will drop.
