  Therefore, an object of the present invention is to provide a reforming apparatus and a reforming system that do not require electrical energy or the like for reforming dry distillation gas.

  In order to solve the above problems, a reformer for reforming a dry distillation gas according to the present invention introduces a dry distillation gas into a reformer vessel and a reformer vessel provided in the reformer vessel. A dry distillation gas inlet for reforming, a reformed gas outlet for discharging the reformed gas that is the reformed dry distillation gas out of the reformer vessel, and an oxidation for introducing an oxidant into the reformer vessel The heat of the dry distillation gas was introduced from the oxidant inlet in the reformer vessel without directly contacting the dry distillation gas introduced from the dry distillation gas inlet and the oxidant introduced from the oxidant inlet. By moving to the oxidant, a heat exchange part for heating the oxidant introduced from the oxidant inlet, and an oxidant release part for releasing the oxidant heated by the heat exchange part into the reformer container, Prepare.

  That is, the reformer of the present invention uses a high-temperature oxidant (heated air, etc.) required for reforming dry distillation gas (to burn part of dry distillation gas) as a target for reforming. It has the structure produced | generated using the heat | fever of the dry distillation gas which has become. The reformed gas / dry distillation gas originally needs to be cooled. Therefore, if this reformer is used, electric energy or the like is not required for reforming the dry distillation gas, and the dry distillation gas is used in a form that effectively uses the heat of the reformed gas / dry distillation gas. Can be improved.

  The reformer of the present invention can be realized as various devices having different specific configurations. For example, the reformer of the present invention has a configuration like a general heat exchanger (however, a heated substance is discharged into the heat exchanger instead of being discharged out of the heat exchanger). ).

  The reforming apparatus of the present invention can also be realized as an apparatus that uses a normal temperature oxidizing agent supplied from an oxidizing agent inlet. However, when the reforming apparatus of the present invention is realized as such an apparatus, it is usually difficult for the dry distillation gas / reformed gas to pass through the inside (the pressure loss relating to the dry distillation gas / reformed gas is relatively large; gasification) If it is connected to the furnace, it will become difficult to produce dry distillation gas from the gasification furnace).

  On the other hand, the reformer according to claim 1 or 2 is a heat exchanger that heats the oxidant using heat of the reformed gas discharged from the reformed gas outlet of the reformer, and heat If the oxidant heated by the exchanger is used in combination with an oxidant flow path that feeds into the reformer from the oxidant inlet, the reformer is equipped with dry distillation gas / reformed gas inside. It can be easy to pass.

(Blanket) unit.

  Next, the configuration of the reformer 20 will be described with reference to FIGS. 4 and 5.

  The reformer 20 (FIG. 4) is a unit composed of a reformer container 20 ′, a plurality of heat receiving pipes 22, a plurality of hot air blowing pipes 23, and the like.

  The reformer container 20 'is a hollow rectangular parallelepiped container with a concave bottom. As shown in FIG. 4, the reformer vessel 20 'has a dry distillation gas inlet 20a provided in the vicinity of the lower end of the vessel, and a reformed gas outlet 20b provided at a position higher than the reformed gas inlet 20a. It is a container.

  Each of the heat receiving pipes 22 has a reformer container 20 ′ so that a substantially horizontal surface is formed on the installation surface of the reformer 20 at the upper end portion thereof and penetrates the reformer container 20 ′. It is a pipe attached to.

  One opening of each heat receiving pipe 22 is connected to a header 21a provided with a heated air inlet 20c, and one opening of each heat receiving pipe 22 is connected to a header 21b.

  Each hot air blowing pipe 23 is a pipe attached to the reformer container 20 'so as to penetrate the reformer container 20' at a position higher than each heat receiving pipe 22 and lower than the lower end of the reformed gas outlet 20b. It is. Each hot air blowing pipe 23 (see FIG. 5) has through-holes formed at various locations in the portion accommodated in the reformer vessel 20 ′.

  One opening of each hot air blowing pipe 23 is sealed by a pipe end closing flange, and the other opening of each hot air blowing pipe 23 is connected to the header 21b via a header 21c.

A punching plate 25 (see FIG. 5) having a plurality of through holes 25a is installed on the plurality of heat receiving pipes 22 in the reformer container 20 ′. The space above the punching plate 25 in the reformer container 20 ′ is filled with a heat storage agent in an amount that fills each hot air blowing pipe 23. This heat storage agent is filled for the purpose of uniformizing the temperature of each part in the reformer vessel 20 ', removing impurities in the reformed gas (and the dry distillation gas during reforming), and the like. Accordingly, it is desirable that the heat storage agent has high specific heat and heat resistance and can withstand acidic gases such as acetic acid, tar, and H ₂ S. Moreover, since it is desired that the heat storage agent is not cemented or has a shape with little pressure loss, a hollow cylindrical ceramic member or the like is used as the heat storage agent.

  At the lower end of the reformer vessel 20 ', an ash removal screw 26 is provided for discharging ash generated by gasification of the raw material to the outside of the furnace. Further, two temperature sensors 42 are attached to the reformer container 20 ′ in order to measure the temperature of the portion of the reformer 20 (the reformer container 20 ′) filled with the heat storage agent. .

  Next, the configuration of the heat exchanger 30 will be described.

As shown in FIG. 6, the heat exchanger 30 includes the inlet and outlet of the heating object and the inlet 3 of the heat source gas.
Five unit heat exchangers 31 having 1x (x = a or b) and outlets 31y (y = b or a) are passed through the unit heat exchangers in order that the reformed gas discharged from the reformer 20 It is a unit connected so that it passes through. In the heat exchanger 30, the two unit heat exchangers 31 on the rear stage function as “heating air generating means including an air inlet 30 c and a heated air outlet 30 d”. In order for the unit heat exchanger 31 to function as “steam generating means having the water inlet 30e and the steam outlet 30f”, the outlet 31y of the heating object of some of the unit heat exchangers 31 is replaced with another unit heat. The unit communicates with the inlet 31x of the heating object of the exchanger.

  Before describing the function of the control device 40, the reason why the gasification furnace 10, the reforming device 20, and the heat exchanger 30 having the above-described configuration are employed in the gasification system according to the present embodiment will be described. I will keep it.

  The structure of the gasification furnace 10 described above is obtained from various experimental results. “A relatively high temperature oxidant (air alone, air and water vapor) is supplied to the lower layer portion of the raw material on the punching plate, and the raw material In addition, it was conceived based on the knowledge that if an unheated oxidant (for example, air) is supplied from above, the raw material (biomass resource) can be gasified in a form that produces less tar and clinker. . Although the reason why the raw material can be gasified with a small amount of tar and the like when the above configuration is adopted has not yet been clarified, the above configuration is not applicable to updraft / downdraft gasifiers. Compared to the configuration, the temperature is adjusted by controlling the supply amount of the oxidant, compared to the configuration in which the gas can easily pass through the raw material to be gasified and the gasification furnace having only one oxidant supply port. It is considered that one of the reasons is that the configuration is easy.

  However, if the oxidant supplied to the gasification furnace 10 is heated with an electric heater, the output power amount of the gasification system is reduced by the amount of power necessary for heating the oxidant. Also, when reforming the dry distillation gas discharged from the gasification furnace 10 with an electric heater, the amount of power required for reforming (heating) the reformed gas is equal to the amount of output power of the gasification system. It will be less.

  Then, if the heat of the oxidant and the reforming of the dry distillation gas are performed using the heat of the dry distillation gas discharged from the gasification furnace 10, a gasification system that does not cause the above problems is realized. I can do it. Therefore, in the gasification system according to the present embodiment, the heat exchanger 30 (FIG. 6) generates steam and heated air supplied to the gasification furnace 10 by using heat of dry distillation gas generated by the gasification furnace 10. ) Is adopted. Further, in the gasification system according to the present embodiment, a reformer 20 (FIG. 4) for reforming dry distillation gas from the gasification furnace 10 by using heated air generated by the heat exchanger 30, more specifically. In the reformer, the heated air generated by the heat exchanger 30 is heated with the dry distillation gas from the gasification furnace 10 and then the dry distillation gas from the gasification furnace 10 is reformed using the heated heating air. 20 is adopted.

  Next, the control content with respect to the gasification system by the control apparatus 40 is demonstrated.

  When the gasification system is operating continuously (steady operation), the control device 40 sets the supply mechanism in the material supply system 50 so that the material is supplied into the gasification furnace 10 at a predetermined speed. Control. Further, the controller 40 controls each flow rate regulating valve in the system so that the temperature of each part in the system (mainly, TC1 to TC7 shown in FIGS. 2 and 4) falls within a predetermined temperature range. The process which controls is also performed.

  This process performed by the control device 40 (hereinafter referred to as a control valve control process for continuous operation) is such that TC5 has a temperature of about 850 ° C to 900 ° C and TC6 has a temperature of about 1050 ° C to 1100 ° C. This process controls each flow control valve in the system.

  More specifically, in the control valve control process for continuous operation, heated air having an appropriate air ratio of about 0.3 to 0.4 is supplied from the second oxidant supply port 10d to supply the first oxidant. The flow rate control valve is controlled so that a larger amount of air than the heated air is supplied from the port 10d. Note that heated air introduced into the second oxidant supply port 10d during continuous operation of the gasification system (that is, heated air generated by the heat exchanger 30 to which a reformed gas of about 1050 ° C. to 1100 ° C. is supplied). Is air at about 400 ° C. to 550 ° C.

  Further, the adjustment valve control process for continuous operation is a process for adjusting TC5 by controlling the air supply amount from the first oxidant supply port 10d in principle.

  When starting the gasification of the raw material in the gasification system, the control device 40 first controls the supply mechanism in the raw material supply system 50 so that a predetermined amount of the raw material is supplied into the gasification furnace 10. . Next, the control device 40 puts about 100 g of solid methanol into the gasifier 10 by controlling the ignition mechanism attached to the ignition port 10 e of the gasifier 10. Moreover, the control apparatus 40 controls the blower connected with the 1st oxidant supply port 10c so that air may be supplied in the gasification furnace 10 from the 1st oxidant supply port 10c.

  Thereafter, the control device 40 indicates that the temperature detection result (TC1 in FIG. 2) by the temperature sensor 42 attached to the uppermost portion of the gasification furnace 10 indicates that the raw material is burned (partial combustion) in the gasification furnace 10. A process of monitoring that the temperature reaches a first predetermined temperature that is set in advance as the temperature when advanced to a certain extent is started.

  When it is found that TC1 has reached the first predetermined temperature, the control device 40 supplies the second oxidant supply port 10d with the heated air outlet 30d of the heat exchanger 30, the heated air from the water vapor outlet 30f, and water vapor. As described above, each flow control valve for heated air and water vapor is controlled. In addition, the control device 40 controls the supply mechanism in the raw material supply system 50 so that a specified amount of the raw material is added into the gasification furnace 10.

  And the control apparatus 40 starts the process which monitors that temperature TC5 of the dry distillation gas discharged | emitted from the gasification furnace 10 turns into predetermined 2nd predetermined temperature, and TC5 becomes 2nd predetermined temperature. If this happens, control is performed to increase the amount of air supplied into the gasifier 10 from the first oxidant supply port 10c.

  The state in which TC5 is at the second predetermined temperature is a state in which no pyrolysis zone is formed in the raw material on the punching plate 11 (the lower layer portion of the raw material on the punching plate 11 is an oxidative decomposition zone, The upper layer portion is in a heating and drying zone).

  Thereafter, the control device 40 starts a process of monitoring that the temperatures TC1 to TC5 of each part of the gasification furnace 10 become temperatures indicating that a pyrolysis zone has been formed in the raw material on the punching plate 11. Then, when the temperatures TC1 to TC5 reach such temperatures, the control device 40 supplies the raw material at a predetermined speed to continuously cause the gasification furnace 10 to gasify the raw material. The operation control process (a process including the control valve control process for continuous operation described above) is started.

<Deformation>
The reforming system according to the above-described embodiment can be variously modified. For example, the reformer 20 can be modified to be capable of supplying room temperature air. For example, as illustrated in FIG. 7, the modification of the reformer 20 to such a device is a heat receiving pipe in which the air supplied to the air inlet 20c ′ crosses the reformer vessel 20 ′. This can be realized by passing through the hot air blowing pipe 23 into the reformer vessel 20 ′ after passing through the pipe 22 a plurality of times (twice in the figure).

  In addition, the reformer 20 can be modified into one that does not contain a heat storage material (a configuration like a general heat exchanger). However, if the heat storage material is built in, the temperature of each part in the reformer container 20 'becomes uniform, and the hot air blowing pipe is caused by impurities in the reformed gas (and the dry distillation gas being reformed). It is also possible to prevent clogging of the 23 through holes. Therefore, although the specific configuration of the reforming device 20 may be different from that described above, it is preferable that the reforming device 20 is a device incorporating a heat storage material.

  In addition, the reforming system may be used in combination with a downdraft / updraft type gasification furnace, or the reforming system may be used in a gasification system for producing methanol or the like. Etc. are natural.
