单床自热式热解气化燃烧反应器及热解气化燃烧方法 Pyrolysis and gasification reactor and a single bed combustion process since the thermal pyrolysis and gasification combustion
 本发明属于固体燃料热解燃烧领域，涉及一种新型的单床自热式热解/气化/燃烧方法及装置。  The present invention belongs to the field of solid fuel combustion pyrolysis, a new single-bed pyrolysis involves self-heating / gasification / combustion method and apparatus.
 固体燃料（煤、生物质等）是世界能源主要组成部分，其燃烧生成的二氧化碳是全球温室气体的主要排放源，因此固体燃料的高效清洁利用是当今能源与环境领域一项重大的技术课题，是关系到国民经济可持续发展的关键因素之一。  solid fuels (coal, biomass, etc.) is a major component of the world's energy, combustion-generated carbon dioxide is the main source of global greenhouse gas emissions, so clean and efficient use of solid fuels is one of today's major energy and environmental areas of technology issues, is one of the key factors related to the sustainable development of the national economy. 固体燃料热解气化可生成合成气（一氧化碳和氢气），合成气是重要的化工气，可以通过费_托合成制油，通过甲烷化反应制天然气，特别是可以通过水汽转换反应去除二氧化碳获得高纯度的氢气，减排二氧化碳。 Pyrolysis and gasification of solid fuels to generate synthesis gas (carbon monoxide and hydrogen), the synthesis gas is an important chemical gas, can be made by Fischer-Tropsch synthesis _ oil, natural gas through methanation reaction, especially the removal of carbon dioxide can be obtained through the water gas shift reaction high purity hydrogen, carbon dioxide emissions. 实现将低品质的固体燃料清洁高效地转化成高价值的产品如车用燃料油和天然气。 Achieve the low quality of clean and efficient solid fuel converted into high-value products such as fuel oil and natural gas vehicles.
 热解与气化反应均为强吸热反应，需要能量维持反应的进行。  Pyrolysis and gasification reactions are strongly endothermic reaction, energy is required to maintain the reaction. 传统的热解炉和气化炉一般是采用加入氧化剂如空气或氧气燃烧部分固体燃烧，由燃烧生成的热量来提供。 Conventional pyrolysis furnace and the gasification furnace is generally used oxidizing agent such as air or oxygen partial combustion of solid fuel, be provided by the heat of combustion generated. 这样带来一些问题：如果是利用空气作氧化剂，空气中大量的N2稀释了产物气，导致反应生成的气体中一氧化碳和氢气含量较低，热值也低，只能作为燃料气使用，不能作为合成气； 如果用纯氧，虽然产物气中没有N2，但制氧过程能耗高且设备投资巨大，经济性较差。 Thus bring some problems: if using air as the oxidant, a large amount of air dilution of the product gas N2, resulting in lower gas produced by the reaction of carbon monoxide and hydrogen content, calorific value is low, only be used as fuel gas, not as synthesis gas; if pure oxygen, although no product gas N2, but the high oxygen consumption and a huge investment in process equipment, poor economy. 另一个热量提供方法是通过壁面传热，由于壁面导热传热效率低，导致设备庞大，能源利用效率低，也难以实现大型化。 Another approach is to provide heat through the wall of heat transfer, heat conduction due to wall heat transfer efficiency is low, resulting in a large equipment, low energy efficiency, it is difficult to achieve large.

 由本发明提出的热解/气化系统如附图2所示。  The present invention is proposed by the pyrolysis / gasification system as shown in Figure 2. 该系统由单床自热式反应器，加料器，产物器冷凝系统，空气烟气换热器，热解气再循环系统等组成。 The system consists of a single-bed self-heating reactors, feeders, product condensate systems, air flue gas heat exchanger, pyrolysis gas recirculation system and other components. 本发明所提出的系统既可以作为气化装置，也可以作为热解装置，用来生产燃料油和合成气。 The proposed system of the present invention either as a gasification apparatus, pyrolysis can also be used as means for the production of synthesis gas and fuel oil.
 固体燃料如生物质、煤或废物衍生燃料（RDF)通过螺旋加料器21加入到底部喷动管，由热解气化介质（再循环热解气或者蒸汽）气力输送到反应器导向管4内，固体采用0-5mm范围的颗粒，以利于气力输送和炉内热解气化反应。  solid fuels such as biomass, coal or waste-derived fuel (RDF) through the screw feeder 21 to join in the end the Ministry spouted tube, conveyed by the pyrolysis and gasification medium (recycled pyrolysis or steam) into the reactor pneumatic guide 4 inner tubes, solid particles using 0-5mm range, in order to facilitate pneumatic conveying and furnace pyrolysis and gasification reactions. 固体燃料颗粒进入导向管后迅速被从导向管下部卷吸孔1进来的高温惰性床料加热至反应温度，反应温度因工艺不同而有所不同，热解制油工艺为450-550°C，气化工艺温度较高，在850-950°C左右；导向管内由于高湍流、高加热速率，物料的热解气化反应剧烈，生成产物气和半焦喷出导向管在热解床5 内形成喷泉，随后气固进行分离，产物气继续上升，而较重的床料和半焦下降落入锥形分隔板6，再通过连接热解床和燃烧床的环形料腿3进入下部燃烧床2内。 After the solid fuel particles from entering the guide tube is sucked quickly from the lower portion of the guide tube hole a volume incoming hot inert bed material is heated to the reaction temperature, the reaction temperature varies due to different processes, pyrolysis oil process is 450-550 ° C, high temperature gasification process at about 850-950 ° C; the guide tube due to the high turbulence, high heating rate, pyrolysis and gasification reactions of violent material to produce the product gas and char spray pyrolysis bed in the guide tube within 5 forming a fountain, followed by gas-solid separation, product gas continues to rise, while the heavier bed material and char fall fall conical partition plate 6, and then by connecting the bed and combustion bed pyrolysis annular combustion material into the lower leg 3 2 bed. 燃烧床采用空气鼓风流化，半焦在该床燃烧，释放的热量用来加热惰性床料，因此该工艺的传热特点主要是通过惰性床料及其内循环为热载体间接将燃烧反应的热量传递给热解气化区，以满足热解气化的热量需求。 Merry bed combustion using air drums, semi-coke in the bed combustion, heat released is used to heat the bed of inert material, so the heat transfer characteristics of the process of heat primarily by an inert bed material and circulation of heat carrier indirectly combustion reaction passed to the pyrolysis and gasification zone, pyrolysis and gasification to meet calorie needs. 燃烧床上部设置惰性床料/催化剂加入口，以补充磨细后飞出的床料和部分工艺如催化热解气化需要加入催化剂的需要。 Burning bed of inert bed material portion provided / catalyst addition port to replenish ground after flying out of bed material and some processes such as catalytic pyrolysis and gasification need to join need a catalyst. 在燃烧床和热解床分别设置气体出口，同时采用双颗粒密封方法，即反应器内环形料腿3和器外旋风分离器7料封，以确保将产物气和燃烧烟气分开。 Combustion gas outlet respectively provided in the bed and the bed pyrolysis, while dual particle sealing method, i.e., the reactor 3 and the annular outer dipleg seal material cyclone 7, to ensure that the product gas and combustion flue gas separately. 热解床的产物气和燃烧床烟气经单独设置的产物气旋风分离器7及烟气旋风分离器8和产物气回料器10及烟气回料器9将夹带的颗粒（细床料和半焦）分离后全部返回燃烧床再循环利用。 Bed pyrolysis product gas and combustion bed flue gas through a separate set of product cyclone cyclone 7 and 8, and the product gas fumes back to the feeder 10 and the smoke back feeder 9 entrained particles (fine bed material All return after and semi-coke) separated combustion bed recycled. 除尘后的热解气化产物气经冷凝器11将轻质油和重质焦油冷却， 不凝结产物气分成两路，一路经第一调节阀门12排出作原料气利用，另一路由第二调节阀门13进入增压风机20加压后作为输送气再进入反应器内。 After the hot dust gasification product gas through the condenser 11 tar light oil and heavy cooling, no condensation product gas is divided into two, all the way through the first discharge valve 12 for regulating the use of the feed gas, the second adjustment another route After the valve 13 into the booster fan 20 as conveying pressurized gas into the reactor again. 燃烧烟气方面，分离颗粒后的燃烧烟气，先经过换热器14回收烟气中的能量，冷却后的烟气经除尘器15再除尘后由引风机16经烟囱17排出。 Combustion flue gas, the combustion flue gas after separating particles, after the first heat exchanger 14 through the flue gas energy recovery, cooled flue gas dust precipitator 15 and then discharged from the chimney draft fan 16 through 17. 燃烧空气先经空气过滤器18过滤后，由鼓风机19经空气预热器14 加热后由风室22进入燃烧床内。 First combustion air after the air filter 18 filters, by a blower 19 after heating the air preheater 14 into the combustion chamber 22 by the air bed.
 固体燃料被热解气携带进入导向管中，热解气在进入导向管时形成高速射流，该高速射流主要有二个作用：其一是卷吸燃烧床内的高温惰性床料，并由下部卷吸孔进入导向管，其二是强化高温惰性床料、固体燃料和气体的混合和传热，使得固体燃料快速加热升温至热解气化所需温度（450-950°C )，固体燃料热解气化生成含一氧化碳和氢气的产物气，经热解床出口排出；残余半焦和惰性床料在热解床中惯性分离，落至锥形分隔板后进入导向管和分隔立管的环隙，再进入燃烧床中。  Pyrolysis solid fuel is carried into the guide tube pyrolysis at high speed when entering the guide tube to form a jet, the high-speed jet has two main functions: one is the entrainment of combustion temperature in the bed of inert bed material, entrainment by the lower part of the hole into the guide tube, and the second is to strengthen the high-temperature inert bed material, mixing and heat transfer solid fuel and gas, making the solid fuel heating up fast pyrolysis and gasification to the desired temperature (450-950 ° C) , pyrolysis and gasification of solid fuels to generate product gas containing carbon monoxide and hydrogen by pyrolysis bed outlet; residual char and inertial separation of inert bed material in the pyrolysis bed, down to the cone separator plate into the guide tube and separate riser annulus, and then into the combustion bed. 燃烧床采用流化床运行方式，用空气作为流化气燃烧半焦，用于加热惰性床料，燃烧烟气由单独出口排出，考虑到惰性床料的跑损或某些工艺要使用催化剂，在燃烧床设有床料/催化剂加入口。 Using fluidized bed combustion operating mode, air is used as the fluidizing gas combustion chars, for heating the inert bed material, combustion flue gas discharged from a single outlet, taking into account the loss or some process running inert bed catalyst material to be used, In the combustion bed has bed material / catalyst addition port. 排出主反应器的产物气和热解气通过外置式旋风分离器分离飞出的较细床料和半焦，由回料器重新送回燃烧床中再利用。 Discharge main reactor product gas and pyrolysis flying through external cyclone separator finer bed material and semi-coke, by returning back to the feeder again burning bed reuse.
