Description

Wood pyrolysis gasification power generation system {BIOMASS GASIFICATION POWER PLANT}

The present invention relates to a wood pyrolysis gasification power generation technology, and more particularly, to a wood pyrolysis gasification power generation system that generates electricity by using high-concentration inflammable gas obtained through wood pyrolysis as a fuel for an internal combustion engine.

Due to the successful implementation of the forest reclamation project, the accumulation of domestic trees is increasing day by day, but the growth of industries that can utilize them industrially and use timber more valuable is not meeting expectations. This is because domestic trees are of low value as lumber, and there is a need for other utilization of domestic trees.

In Korea, the heavy chemical industry accounts for a large portion of the entire industry, making it a country with enormous carbon dioxide emissions, and it is necessary to produce energy while reducing carbon dioxide emissions.

On the other hand, wood, which has been used by mankind for a long time, has been an important energy supply source along with coal, oil, and natural gas, which are more powerful and easy to collect in large quantities. However, unlike wood, fossil fuels not only cause various environmental pollution, but also the need to utilize existing resources such as wood is increasing in that resources are expected to be depleted within a predetermined period of time.

When electricity is generated with inflammable gas generated by pyrolysis of wood and charcoal, a by-product, is returned to the soil at the same time, about 1/3 of the carbon that trees have fixed in the air through photosynthesis is fixed as charcoal for a long period of time (100 to 1000 years), generating electricity can produce energy.

Specifically, when heat is applied to wood, first, moisture evaporates, and then thermal decomposition may occur in the order of hemicellulose, cellulose, and lignin. At 300 to 400 degrees, wood can turn black and carbonization can proceed. At this time, charcoal may appear to be pure carbon, but may include various elements other than carbon. Therefore, it may correspond to charcoal having a high carbon content, but may not correspond to a 100% perfect carbon body. On the other hand, chemical changes occur actively up to a thermal decomposition temperature of 1,000 to 1,500 degrees, and the corresponding process may correspond to a carbonization process. In addition, when the temperature exceeds 1,800 to 2,000 degrees, major changes occur in arrangement arrangement of carbon atoms and crystal growth, and the corresponding process may correspond to a graphitization process.

The wood pyrolysis gasification power generation system according to the present invention can produce electricity through a generator using gas generated during the pyrolysis of wood as fuel, and the configuration and operation of the present invention will be described in more detail below.

1 is a diagram explaining the basic configuration of a wood pyrolysis gasification power generation system.

Referring to FIG. 1 , a wood pyrolysis gasification power generation system may be implemented including an inflammable gas generator, a power supply unit, and an electricity generation unit.

The inflammable gas generator may correspond to a device that heats and pyrolyzes wood and generates inflammable gas as a result. The specific configuration and operating method of the inflammable gas generator may be implemented through various implementations. In addition, the inflammable gas generating unit may adopt various structures depending on the interaction between the power supply unit and the electricity generating unit.

The power supply unit may produce power for electricity generation. To this end, the power supply unit may receive the inflammable gas from the inflammable gas generating unit. In addition, the power supply unit may be implemented in various structures depending on the structure and coupling method of the inflammable gas generator unit and the electricity generator unit.

The electricity generating unit may generate electricity using power supplied by the power supply unit. Electricity generated by the electricity generating unit may be transmitted to the outside through a power line. It may be implemented in a structure corresponding to the power production and transmission method of the power supply unit, and specific configuration and operation may vary according to the electricity generation method.

2 is a diagram illustrating a wood pyrolysis gasification power generation system according to the present invention.

Referring to FIG. 2, the wood pyrolysis gasification power generation system 200 includes a ignited gas generator 210, a power supply 220, a ignited gas purifier 230, a carbon supply valve 240, and an electricity generator 250. , It may include an electric heating unit 260 and a control unit (not shown in FIG. 1).

The inflammable gas generating unit 210 may generate high-concentration inflammable gas by thermally decomposing wood. To this end, the inflammable gas generator 210 may be implemented by including a thermal decomposition device that thermally decomposes wood. The pyrolysis device can generate high-concentration inflammable gas by heating and gasifying wood. The pyrolysis device may include a container for accommodating wood and a heating device for heating it. The ignition gas generator 210 may include a collection device for collecting the ignition gas generated by the pyrolysis device in a predetermined space and a transport pipe for transporting the collected ignition gas to another space.

For example, the inflammable gas collected by the collecting device may include methane, carbon monoxide, carbon dioxide, hydrogen, water, tar, and the like generated by thermal decomposition of wood. The ignition gas generated by the ignition gas generator 210 is transmitted to the power supply unit 220 and may be used to operate an internal combustion engine for power generation.

In one embodiment, the ignition gas generator 210 may use wood dried in a state having a specific moisture content according to the characteristics of wood. For example, the inflammable gas generator 210 may use dried wood having a moisture content of 2.5 to 5.6%. In this case, the inflammable gas generator 210 may pyrolyze wood by controlling the pyrolysis device as follows. That is, the ignition gas generating unit 210 injects nitrogen gas at a flow rate of 74 to 105 ml/min into the pyrolysis device, maintains a nitrogen gas pressure of 0.05 to 0.95 MPa, and starts the heating temperature at 10 to 15 degrees and finally It can be raised to 430 ~ 575 degrees to proceed with the pyrolysis process. In addition, the inflammable gas generator 210 may be adjusted to a temperature rise rate of 5 to 14 degrees/minute, and the thermal decomposition process may be performed by maintaining the final temperature for 45 to 65 minutes. On the other hand, it goes without saying that the inflammable gas generating unit 210 can pyrolyze by changing the above specific settings to various combinations as needed.

The power supply unit 220 may produce power for electricity generation using ignited gas. To this end, the power supply unit 220 may be implemented by including a power device that generates power using inflammable gas. In this case, the power device may correspond to an internal combustion engine, and may include a gas engine, a gasoline engine, a diesel engine, a gas turbine, and the like.

In addition, the power supply unit 220 can improve the durability and efficiency of the internal combustion engine by using the ignition gas purified through a separate purification step instead of using the ignition gas delivered from the ignition gas generator 210 as it is. Energy efficiency can be increased by improving the combustibility of inflammable gas.

In one embodiment, the power supply unit 220 may generate power by operating an internal combustion engine including a compression ignition type gasoline engine and a compression ignition type diesel engine based on inflammable gas. Meanwhile, the power supply unit 220 may be implemented by including a plurality of internal combustion engines, and in this case, each of the plurality of internal combustion engines may operate independently connected to a transport pipe transporting inflammable gas.

The ignition gas purification unit 230 is connected to the power supply unit 220 through a pipe to receive water vapor and tar in the ignition gas and remove the water vapor and tar through the first carbon gas having a specific temperature. That is, the inflammable gas purification unit 230 can react the water group and tar of the inflammable gas with high-temperature carbon, and at this time, when the tar touches the high-temperature carbon mass, it can be decomposed into smaller carbides such as methane and ethane. Combustibility of flammable gas can be improved. Meanwhile, the ignition gas purification unit 230 may be directly connected to the power supply unit 220 through a pipe to receive the ignition gas. For example, the ignition gas purification unit 230 may be located above the power supply unit 220, and may more smoothly process gas reception through a pipe by using a convection phenomenon of the ignition gas.

In one embodiment, the phosphorus gas purification unit 230 decomposes water molecules of water vapor through the first carbon gas to reduce carbon monoxide (CO) and methane (CH ₄ ). At this time, the first carbon gas may provide a high purification effect by maintaining a high temperature equal to or higher than a specific temperature. More specifically, carbon heated to 1000 degrees or more can effectively decompose water molecules by combining with hydrogen of water molecules with strong binding force. Carbon monoxide and methane thermally decomposed by carbon are combustible gases and can improve the combustibility of inflammable gases.

The carbon supply valve 240 may be disposed in a pipe connecting the power supply unit 220 and the ignition gas purification unit 230, and may measure the temperature of the first carbon gas passing through the pipe through a temperature sensor. . The carbon supply valve 240 may block the introduction of the first carbon gas when the temperature of the first carbon gas is equal to or less than a specific temperature. In one embodiment, the carbon supply valve 240 may be connected to a pipe through which the second carbon heated by the electric heating unit 260 passes. In this case, the carbon supply valve 240 may block the introduction of the second carbon gas when the temperature of the second carbon gas is equal to or less than a specific temperature.

The electricity generating unit 250 may generate power using the power provided by the power supply unit 220 . To this end, the electricity generator 250 may be implemented by including a separate generator, and the generator may be implemented in various forms. The electricity generator 250 may be implemented to directly receive power from the internal combustion engine by being connected to the internal combustion engine of the power supply unit 220 .

In one embodiment, the electricity generator 250 may convert AC electricity of generated power into DC electricity and supply it to an external power grid through a general-purpose grid-tie inverter. Here, the grid-tie inverter may correspond to a type of power inverter that converts direct current (DC) from a solar panel or wind turbine into alternating current (AC). A grid-tied inverter differs from other types of power inverters in that it is tied to the grid and can be sold to the power company by supplying excess AC current back to the grid, which can be either a grid-interactive inverter or an asynchronous inverter.

The electric heating unit 260 may heat the carbon gas to a specific temperature or higher by using a part of the power generated by the electricity generating unit 250 based on the labyrinth structure. The electric heating unit 260 may be connected to the ignition gas purification unit 230 and the carbon supply valve 340 through a pipe, respectively, and receives the low-temperature carbon gas from the ignition gas purification unit 230 and heats the carbon gas above a specific temperature. Carbon gas may be delivered in the direction of the carbon supply valve 340 .

In addition, the electric heating unit 260 may provide the second carbon gas to the phosphorus gas purifying unit 230 as the first carbon gas by controlling a speed at which the second carbon gas passes through the labyrinth structure. At this time, the second carbon gas heated by the electric heating unit 360 may pass through the carbon supply valve 240 connected through a pipe and return to the inflammable gas purification unit 230 . Meanwhile, the electric heating unit 260 may receive the carbon gas by being connected to a separate supply device that independently provides the carbon gas. The carbon gas supplied from the outside and the carbon gas received through the phosphorus gas purification unit 230 may be heated together while passing through the labyrinth structure.

In one embodiment, the electric heating unit 260 may maintain the carbon gas at a temperature of at least 1000 degrees. That is, in order to remove water vapor and tar from inflammable gas, high-temperature carbon may be required, and in this case, the temperature of the carbon needs to be maintained at least 1000 degrees or higher. In particular, since the bond between carbon and water molecules is an endothermic reaction that absorbs heat, the temperature of the carbon must always be maintained above a certain temperature, and the electric heating unit 260 converts the carbon gas whose temperature has fallen during the purification process to electrical By heating in this way, the temperature of the carbon gas can be forcibly raised to a set temperature or higher.

In one embodiment, the electric heating unit 260 is a heating tube for forming a labyrinth structure and heating the second carbon gas, an induction coil formed along the outside of the heating tube, and a speed of the second carbon gas passing through the heating tube. An anemometer for measuring and a current controller for controlling power supply to the induction coil based on the speed of the second carbon gas may be included. That is, the electric heating unit 260 may be implemented to electrically heat carbon by using the property of carbon as a conductor.

More specifically, the heating tube may be implemented to form a labyrinth structure inside the electric heating unit 260 . The heating tube may be implemented in the form of a pipe through which carbon gas passes, and may be designed to effectively absorb heat transferred in the process of passing through a complicatedly entangled pipe like a maze.

In one embodiment, the heating tube is composed of a plurality of subtubes forming a labyrinth structure, and at least one of the plurality of subtubes is rotated in a horizontal or vertical direction according to a control signal from a current controller, thereby dynamically changing the labyrinth structure. It can be implemented to make this possible. That is, the heating tube may be composed of a plurality of partial tubes and a plurality of connecting tubes connecting the partial tubes. In particular, each of the plurality of partial tubes may rotate in a vertical or horizontal direction, and may be connected to different connectors in a vertical or horizontal direction according to each rotation. The current controller can dynamically change the labyrinth structure formed by the heating tube in consideration of various conditions. The change operation may be performed by determining the rotation direction of each of the plurality of subpipes and rotating them in the corresponding direction, and the connecting pipes may be implemented to automatically perform separation and coupling operations with adjacent subpipes according to the change operation.

The induction coil may be implemented in a form surrounding the outside of the heating tube, and may serve to directly transfer heat to the carbon gas inside the heating tube in an electrical manner. In one embodiment, a plurality of induction coils may be formed, and various arrangement structures between induction coils may be applied according to the shape and structure of the heating tube. For example, when the heating tube is formed in a cylindrical shape, the induction coil may be formed inside and outside the heating tube and operated. In addition, when the heating tube is formed as a single cylindrical tube, induction coils may be arranged side by side.

In addition, the anemometer may operate while being coupled to the heating tube, and may be implemented to measure the velocity of carbon gas passing through the inside of the heating tube. The anemometer may be installed at a specific location of the heating tube, and may be formed in plurality in some cases. The current controller may control the temperature of the heated carbon gas by adjusting the amount of power provided to the induction coil. For example, the current controller can increase the amount of power supplied to the induction coil as the speed of the carbon gas passing through the heating tube increases, and conversely, it can reduce the amount of power supplied to the induction coil as the speed of the carbon gas decreases.

In one embodiment, the current controller may adjust the power supply according to the speed of the second carbon gas and the carbon density inside the heating tube. For example, the current controller can reduce the amount of power supplied to the induction coil when the carbon density is high even at the same speed, and increase the amount of power supplied to the induction coil when the carbon density is low even at the same speed. In addition, the current controller can increase the amount of power supplied to the induction coil when the speed of the carbon gas is high even in the case of the same carbon density, and reduce the amount of power supplied to the induction coil when the speed of the carbon gas is low even in the case of the same carbon density. can

In one embodiment, the current controller may adjust the frequency and power supply of the induction coil according to the speed of the second carbon gas, the current temperature, and the carbon density inside the heating tube. For example, the current controller may lower the frequency of the induction coil as the current temperature of the carbon gas increases, and increase the frequency of the induction coil as the current temperature of the carbon gas decreases.

The control unit (not shown in FIG. 1) controls the overall operation of the wood pyrolysis gasification power generation system 200, and includes the ignition gas generator 210, the power supply unit 220, the ignition gas purification unit 230, and the carbon supply valve.
