The first gas entering branch pipe 622 enters the first combustion chamber 621 for combustion, and at the same time, because the combustion exhaust gas main pipe 669 and the first combustion exhaust gas pipe are 6691 In the phase cut-off state, the corresponding combustion exhaust gas main pipe 669 and the second combustion exhaust gas main pipe 6693 are in an on state, so that the exhaust gas in the first combustion chamber 621 can only pass through the outer fire passage partition wall 625 The upper combustion chamber through hole 6251 enters the second combustion chamber 601, passes through the second regenerator 606, and passes through the second regenerator 603 in the second regenerator 606.

( 4 )空气风机 664 将空气鼓入空气主管 667 、空气依次进入经过空气连接管 6672 、第二空气分管 6673 、第二空气围管 6675 、第二空气进入支管 607 进入到第二蓄热腔 606 ,利用第二蓄热腔 606 中的第二蓄热体 603 释放的热量对空气进行加热后进入第二燃烧室 601 中;同时,煤气风机 665 将荒煤气经过回收净后得到净煤气鼓入煤气主管 668 ,煤气依次进入煤气连接管 6682 、第二煤气分管 6683 、第二煤气围管 6685 、第二煤气进入支管 602 进入第二燃烧室 601 中进行燃烧,与此同时,因为燃烧废气主管 669 和第一燃烧废气分管 6691 相接通,而相应燃烧废气主管 669 和第二燃烧废气分管 6693 处于相切断状态,所以第二燃烧室 601 中煤气燃烧后的废气只能通过外火道隔墙 625 上部的燃烧室通孔 6251 进入第一燃烧室 621 中,再经过第一蓄热腔 626 ,经第一蓄热腔 626 中的第一蓄热体 603 进行吸热降温后,最后从第一燃烧废气排出支管 628 、第一燃烧废气围管 6694 、第一燃烧废气分管 6691 、燃烧废气主管 669 通过废气风机 666 排出,所以外燃气加热装置 64 燃烧原理在于当第一燃烧室 621 中煤气燃烧后生成的废气从燃烧室通孔 6251 进入第二燃烧室 601 ,经第二燃烧室 601 及第二蓄热腔 606 中第二蓄热体 603 对其余热吸收降温后排出,反之,当第二燃烧室 601 中煤气燃烧后生成的废气从燃烧室通孔 6251 进入第一燃烧室 621 ,经第一燃烧室 621 及第一蓄热腔 606 中第一蓄热体 603 对其余热吸收降温后排出。 (4) Air blower 664 Air is blown into the air main 667, and the air enters the air connecting pipe 6672 in sequence. The second air pipe 6673, the second air pipe 6675, and the second air inlet pipe 607 enter the second heat storage chamber 606, and the second heat storage body 603 in the second heat storage chamber 606 is utilized. The released heat heats the air and enters the second combustion chamber 601. At the same time, the gas blower 665 recovers the waste gas and then obtains the net gas into the gas main pipe 668, and the gas enters the gas connecting pipe in turn. 6682, the second gas pipe 6683, the second gas pipe 6685, the second gas entering branch pipe 602 enter the second combustion chamber 601 for combustion, and at the same time, because of the combustion exhaust pipe 669 is connected to the first combustion exhaust gas branch 6691, and the corresponding combustion exhaust gas main pipe 669 and the second combustion exhaust gas main pipe 6693 are in a phase cut state, so the second combustion chamber 601 The exhaust gas after the combustion of the medium gas can only enter the first combustion chamber 621 through the upper combustion chamber through hole 6251 of the outer fire passage partition wall 625, and then passes through the first regenerator chamber 626 and passes through the first regenerator chamber 626. After the first heat accumulator 603 is subjected to heat absorption and cooling, finally, the first combustion exhaust gas discharge branch pipe 628, the first combustion exhaust gas surrounding pipe 6694, the first combustion exhaust gas pipe 6691, and the combustion exhaust gas main pipe 669 Exhaust by the exhaust fan 666, the external gas heating device 64 is based on the principle that the exhaust gas generated after the combustion of the gas in the first combustion chamber 621 enters the second combustion chamber from the combustion chamber through hole 6251. The second heat accumulator 603 in the second combustion chamber 601 and the second regenerator 606 is cooled after the remaining heat absorption, and conversely, the exhaust gas generated after the combustion of the gas in the second combustion chamber 601 is through the combustion chamber through hole. 6251 enters the first combustion chamber 621, and is cooled by the first heat storage body 603 in the first combustion chamber 621 and the first heat storage chamber 606 to cool down the remaining heat absorption.
综上所述,这种通过气体换向装置的气体两进一出的工作方式和蓄热换热器的蓄热换热的工作方式,实现两组关联的燃气加热器交替燃烧,即气体换向装置向第一燃气加热器的燃烧室送入空气、净煤气燃烧,同时从第二燃气加热器的燃烧室中吸出燃烧后的热废气,热废气经第二燃气加热器的第二蓄热换热器中的第二蓄热体吸热降温变为温度相对较低的低温废气排出;同理,气体换向装置向第二燃气加热器的燃烧室送入空气、净煤气燃烧, 同时从第一燃气加热器的燃烧室中吸出燃烧后的热废气,热废气经第一燃气加热器的第一蓄热换热器中的第一蓄热体吸热降温变为温度相对较低的低温废气排出;这种相互利用煤气燃烧后的废气余热进行加热空气的方法,既起到了对煤气燃烧后的废气余热充分利用,提高燃烧室中的煤气的燃烧效率,又能对煤气燃烧后的废气进行一定程度的降温,不用消耗外来能源,起到节能降耗的目的,节省煤矸石热解气化成本。 In summary, the two-in-one operation mode of the gas through the gas reversing device and the heat storage heat exchange operation mode of the regenerative heat exchanger realize the alternating combustion of the two gas heaters associated with the two groups, that is, the gas exchange Feeding air to the combustion chamber of the first gas heater to the combustion chamber, and combusting the hot exhaust gas from the combustion chamber of the second gas heater, and the second heat storage of the hot exhaust gas through the second gas heater The heat absorption and cooling of the second heat storage body in the heat exchanger is changed to a low temperature exhaust gas with a relatively low temperature; similarly, the gas reversing device sends air to the combustion chamber of the second gas heater, and the net gas is burned. At the same time, the hot exhaust gas after combustion is sucked from the combustion chamber of the first gas heater, and the hot exhaust gas is cooled to a relatively low temperature by the first heat storage body in the first heat storage heat exchanger of the first gas heater. The low-temperature exhaust gas is discharged; the method of heating the air by using the waste heat of the exhaust gas after combustion of the gas not only makes full use of the waste heat of the exhaust gas after the combustion of the gas, but also improves the combustion efficiency of the gas in the combustion chamber, and can burn the gas after the gas is burned. The exhaust gas is cooled to a certain extent, without consuming external energy, saving energy and reducing consumption, and saving coal gangue pyrolysis gasification cost.

本发明的水煤气反应原理方法是: The principle of the water gas reaction principle of the present invention is:
( 1 )、蒸汽包 754 中水蒸汽通过 汽包输入管 752 和蒸汽进入通管 707 向 物料降温装置 70 的 低温 降温 室 702 通入水蒸汽,水蒸汽吹向低温 降温 室 702 ,除给低温 降温 室 702 中热解气化后的固体产物降温之外,水蒸汽向上串入高温 降温 室 701 ,给从热解气化室 61 落入高温 降温 室 701 中大量的热解气化后的高温固体产物降温,水蒸汽 在 给热解气化后的固体进行降温 的同时,提高蒸汽温度 形成过热水蒸汽; (1) The steam in the steam package 754 passes through the steam inlet pipe 752 and the steam enters the pipe 707 to the material cooling device. The low temperature cooling chamber 702 of 70 is supplied with water vapor, and the water vapor is blown to the low temperature cooling chamber 702, except for the low temperature cooling chamber 702. In addition to the cooling of the solid product after the pyrolysis gasification, the water vapor is cascaded into the high temperature cooling chamber 701, and falls from the pyrolysis gasification chamber 61 into the high temperature cooling chamber 701. A large amount of pyrolysis and gasification of the high-temperature solid product is cooled, and the steam is cooled by the pyrolysis gasification solids, and the steam temperature is increased to form superheated steam;
( 2 )、过热水蒸汽穿过中心支撑弓 65 进入 热解气化室 61 , 并与 热解气化室 61 的 高温煤矸石热解物料接触, 煤矸石热解后固体产物中的炭与过热水蒸汽相遇进行水煤气反应生成水煤气(一氧化碳和氢气) ; (2), the superheated steam passes through the central support bow 65 into the pyrolysis gasification chamber 61, and with the pyrolysis gasification chamber 61 The high temperature coal gangue pyrolysis material contacts, after the coal gangue pyrolysis, the carbon in the solid product meets the superheated steam to react with water gas to form water gas (carbon monoxide and hydrogen);
( 3 )、 煤矸石热解气化后的固体产物从热解气化室 61 中落入 物料降温装置 70 的高温降温室 701 和 低温降温室 702 中,对经过低温降温室 702 和 高温降温室 701 向上进入热解气化室 61 的水蒸汽再次加热成为过热的高温水蒸汽 ,同时又对 煤矸石热解气化后的固体产物进行降温 ,再利用低温降温室 702 中 固体产物余热给 炉体水包 753 中的水加热形成水蒸汽,水蒸汽通过 汽包输入管 751 进入 蒸汽包 754 中,给蒸汽包 754 中补充因水煤气反应而消耗的大量水蒸汽,使得水煤气反应能够连续不间断进行。 (3) The solid product after pyrolysis and gasification of coal gangue falls from the pyrolysis gasification chamber 61 into the high temperature drop greenhouse of the material cooling device 70 In the 701 and low temperature falling greenhouse 702, the water vapor that has passed through the low temperature falling greenhouse 702 and the high temperature falling greenhouse 701 into the pyrolysis gasification chamber 61 is reheated into superheated high temperature steam. At the same time, the solid product after pyrolysis and gasification of coal gangue is cooled, and then the waste heat of the solid product in the low temperature drop greenhouse 702 is heated to form water vapor in the water of the furnace body water bag 753, and the water vapor passes through the steam drum inlet pipe. 751 Entering the steam package 754, the steam package 754 is replenished with a large amount of water vapor consumed by the water gas reaction, so that the water gas reaction can be continuously performed without interruption.
本发明的 水煤气反应大量生成是在 热解气化室 61 中下部进行,这是因为在此段热解气化室中的煤矸石已经热解相对充分,温度也相对较高,此时从热解气化室 61 的底部通入高温过热的水蒸汽,过热的水蒸汽与煤矸石热解后的固体产物中的炭相激就会产生大量的水煤气; 当然,水蒸汽在给高温降温室 701 和 低温降温室 702 中 煤矸石热解气化后的固体产物降温过程中,与煤矸石热解气化后的固体产物中残余的炭也会产生水煤气,但是产生的量相对较小,这与煤矸石热解气化后的固体产物中残余的炭本身量不多, 水蒸汽温度也不是太高有关。 The large amount of water gas reaction of the present invention is generated in the pyrolysis gasification chamber 61 The middle and lower parts are carried out because the coal gangue in the pyrolysis gasification chamber in this section has been relatively pyrolyzed and the temperature is relatively high, at this time from the pyrolysis gasification chamber 61 The bottom of the water is heated by high temperature and superheated water. The superheated steam and the carbon in the solid product after the coal gangue pyrolysis produce a large amount of water gas; of course, the water vapor is in the high temperature drop greenhouse 701 and the low temperature drop greenhouse 702 Medium During the cooling process of the solid product after pyrolysis and gasification of coal gangue, the residual carbon in the solid product after pyrolysis and gasification of coal gangue also produces water gas, but the amount produced is relatively small, which is related to the pyrolysis gasification of coal gangue. The amount of residual carbon in the subsequent solid product is not much, The water vapor temperature is not too high.
本发明利用自 煤矸石热解气化后的温度相对较低的固体产物 的余热进行热传递产生水蒸汽,再利用水蒸汽与温度较高的 固体产物直接接触产生过热水蒸汽,达到水煤气反应的所需温度,促进水煤气反应更加充份 ,既在降低 固体产物 温度的同时,又产生水蒸汽和过热蒸汽,这种不需要消耗额外能源的技术方法符合我们今天倡导的节能降耗,可持续发展的理念。 The present invention utilizes a relatively low temperature solid product after pyrolysis gasification from coal gangue The waste heat is transferred by heat to generate water vapor, and then the steam is directly contacted with the solid product with higher temperature to generate superheated steam to reach the required temperature of the water gas reaction, thereby promoting the water gas reaction more fully, both reducing the solid product. At the same time of temperature, water vapor and superheated steam are generated. This technical method that does not require additional energy is in line with the concept of sustainable energy conservation and sustainable development that we advocate today.
