Description

Technical Field

[0001] The invention relates to the technical field of pyrolysis and gasification, and specifically to an integrated process for pyrolysis and gasification of carbon-containing energy, dust removal, quality improvement and purification. Background Art

[0002] With the advancement of urbanization and the continuous improvement of the level of social development, based on the prevention and control principles of "reduction, resource utilization and harmlessness", the existing large-scale solid waste treatment methods mainly include landfill, composting and incineration. The solid waste composition is complex and contains many harmful substances. Long-term extensive storage and low-value utilization occupy a large amount of land.

[0003] However, the main problems of the existing direct incineration-based thermal disposal technology are low energy efficiency and difficulty in controlling the emission of key pollutants such as dioxins. Dust removal and purification and gas quality improvement are the key to clean and efficient use of raw gas and increase of product added value in the organic solid waste pyrolysis and gasification graded conversion process. In the past, solid heat carriers were used as heat sources to pyrolyze and gasify organic solid waste. Cyclone separators were used for dust removal, but experiments found that the separators could only separate carbon particles from oil and gas, while the remaining oil and gas still contained tar, which was easy to adhere to the inner wall of the pipeline during subsequent transportation;

[0004] At the same time, due to the heavy tar of rapid pyrolysis and the presence of pollutants and dust such as sulfur, nitrogen, and chlorine in the gasification gas of organic solid waste, the development of cheap, highly active, long-life, and renewable catalysts is extremely difficult, and existing catalysts cannot be used in industrial processes. On the other hand, the disposal of deactivated catalysts will cause the water-soluble transition metal ions contained in them to harm the environment. At the same time, the frequent replacement of catalysts in industrial applications also increases production costs and operational difficulties.

[0005] Therefore, an integrated process of pyrolysis, gasification, dust removal, quality improvement and purification of carbon-containing energy is designed to improve energy utilization efficiency and quality to solve such defects. Summary of the invention

[0022] Beneficial Effects

[0023] The present invention provides an integrated process for pyrolysis, gasification, dust removal, quality improvement and purification of carbon-containing energy. Compared with the existing technology, it has the following beneficial effects:

[0024] (1) The integrated process of pyrolysis and gasification of carbon-containing energy for dust removal, quality improvement and purification uses a pyrolysis and gasification mechanism and a catalytic reaction mechanism in combination. The arrangement of these two mechanisms allows the oil and gas generated after the pyrolysis of garbage in the pyrolysis and gasification furnace to be separated by a gas-solid separator, thereby allowing the high-temperature carbon particles to be reintroduced into the inner side of the carbonization heating furnace. At the same time, by utilizing the upward drive of the cylinder and the linkage between the structures, the treated catalyst in the cylinder can be connected to the garbage for unloading, and the high-temperature catalyst enters the carbonization heating furnace as a heating source, thereby effectively improving the energy utilization efficiency and reducing fuel loss. At the same time, the gas filtered by the catalyst is purer and the quality is improved.

[0025] (2) The integrated process of pyrolysis and gasification of carbon-containing energy for dust removal, quality improvement and purification is provided with a conical mesh frame on the inner side of the blanking ring cylinder, and is used in combination with a straight cylinder frame and a material holding rotating plate. The arrangement of these structures can, after the pyrolysis and gasification of the garbage inside the pyrolysis and gasification furnace is completed and carbonized, use the lifting and lowering of the cylinder to drive the conical mesh frame to rise, so that the high-temperature carbonized garbage inside falls into the inner side of the carbonization heating furnace as a heating source. At the same time, after the cylinder is lowered, the rectangular pressing plate is used to press the material holding rotating plate to turn it over, and the garbage is poured into the inner side of the pyrolysis and gasification furnace for pyrolysis, thereby completing the transfer of the carbonized garbage and the dumping and loading of new garbage in turn, effectively improving the overall efficiency.

[0026] (3) The integrated process of pyrolysis, gasification, dust removal, quality improvement and purification of carbon-containing energy is achieved by installing a heat exchange frame on the surface and rear of the feed box, and installing a heat exchange duct on the inner side of the heat exchange frame, and using it in conjunction with a gas-solid separator. The arrangement of these structures can use the gas-solid separator to separate the high-temperature carbon particles in the oil and gas, and then let the heat exchange duct reintroduce them into the carbonization heating furnace as a heating source. In the process, the heat exchange frame will emit temperature to the inside of the feed box, thereby pre-heating and drying the garbage inside the feed box, thereby improving the efficiency of subsequent pyrolysis and gasification, and at the same time better utilizing energy.

[0027] (4) The integrated process of pyrolysis, gasification, dust removal, quality improvement and purification of carbon-containing energy is achieved by installing a catalytic filter box on the right side of the pyrolysis gasifier, and using it in combination with a catalytic box and a return inclined pipe. The arrangement of these structures can utilize dolomite catalyst to catalytically treat the oil and gas, thereby reducing the tar present in the oil and gas, ensuring that the inside of the pipeline will not stick during transportation, improving the quality of the fuel gas, and also avoiding the huge energy consumption of heating the oil and gas after condensation. In addition, the raw material price of dolomite catalyst is low, and it can be used directly as a heating source after the catalysis is completed, without the need for repeated and cumbersome regeneration, thereby reducing the catalytic cost and the cumbersomeness of replacing the catalyst.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-12 The present invention provides a technical solution: an integrated process for pyrolysis, gasification, dust removal, quality improvement and purification of carbon-containing energy, which specifically includes the following steps:

[0043] S1. Garbage feeding: Garbage is fed into the feeding box 112 in the pyrolysis gasification mechanism 1, and then the material transfer plate 113 is turned over to pour the garbage into the pyrolysis gasification furnace 104;

[0044] S2, heating in the furnace: using the igniter 121 to first heat the interior of the carbonization heating furnace 102;

[0045] S3, gasification decomposition: using the high-temperature flue gas from combustion to decompose the garbage inside the pyrolysis gasification furnace 104;

[0046] S4, flue gas filtration: filtering the flue gas using the catalyst in the catalytic reaction mechanism 2;

[0047] S5. Lifting and replacing materials: Start the cylinder 122 to pour the garbage in the pyrolysis gasification furnace 104 into the carbonization heating furnace 102, and replace the catalyst in the catalyst box 202 at the same time.

[0048] The above-mentioned integrated process of pyrolysis, gasification, dust removal, quality improvement and purification of carbon-containing energy has the following more specific steps:

[0049] S1. Garbage feeding: First, organic solid garbage is put into the inner side of the feeding box 112, so that the garbage is piled on the top of the material holding rotating plate 113, and then the cylinder 122 uses the lifting vertical rod 123 to pull the U-shaped lifting frame 125 and the polygonal lifting cylinder 124 to rise together. After the polygonal lifting cylinder 124 rises, it will pull the polygonal vertical rod 109 to the inner side of the inner groove rotating rod 107, and drive the conical net frame 110 to rise and separate from the blanking ring cylinder 103. The frame 110 continues to rise. At this time, the rectangular pressing plate 128 enters the inner side of the side shift opening 115 and is squeezed by the material holding rotating plate 113. The rectangular pressing plate 128 flips downward and does not produce a hard pressure with the material holding rotating plate 113. When the conical screen frame 110 rises to the top, the rectangular pressing plate 128 moves to the upper part of the inner side of the side shift opening 115, and then rotates the rectangular pressing plate 128 under the torsion of the torsion spring rotating rod 127 to make it become a horizontal state, and then the cylinder 122 starts to bring The polygonal lifting cylinder 124 and the U-shaped lifting frame 125 slide down, and when the polygonal lifting cylinder 124 descends, the conical screen frame 110 will be lowered first. After the conical screen frame 110 is completely lowered to the inside of the blanking ring cylinder 103, the rectangular pressing plate 128 contacts the top of the material holding rotating plate 113. As the cylinder 122 continues to descend, the lifting vertical rod 123 will be used to press the straight cylinder frame 126 to descend. At this time, the rectangular pressing plate 128 presses the material holding rotating plate 113 to flip downward. Tilt, at this time, the garbage on the top of the material holding rotating plate 113 slides to the inner side of the pyrolysis gasification furnace 104 and is located on the top of the conical net frame 110, and the rectangular pressing plate 128 continues to descend and separates from the top of the material holding rotating plate 113. At this time, the material holding rotating plate 113 is flipped and reset by its own weight, and the isolation baffle 114 is reset to close the feeding box 112, and then a batch of garbage is put from the top of the feeding box 112 to the top of the material holding rotating plate 113, and then go to step S2;

[0050] S2, heating in the furnace: after the garbage enters the pyrolysis gasification furnace 104, the igniter 121 is started to ignite and heat the interior of the carbonization heating furnace 102 with external fuel. After the temperature inside the carbonization heating furnace 102 rises, the heat will pass through the conical mesh frame 110 to pyrolyze and gasify the garbage inside the pyrolysis gasification furnace 104;

[0051] S3, gasification and decomposition: during the heating process, the garbage will produce derivative carbon. At this time, during the rising process of the air flow, the unreacted garbage, derivative carbon and volatiles will react with the hydrogen-rich atmosphere and water vapor in the middle and upper part of the pyrolysis gasification furnace 104 to undergo volatile reforming reaction to generate pyrolysis oil and gas. Then the gas-solid separator 118 draws in the oil and gas at the top and performs gas-solid separation. The separated high-temperature derivative carbon particles flow into the inner side of the heat exchange conduit 117 through the U-shaped air frame 119 and then pass through the heat exchange frame 116. At this time, the garbage inside the feeding box 112 will be heated and dried in advance by the temperature emitted by the heat exchange frame 116, until the high-temperature carbon particles enter the interior of the carbonization heating furnace 102 through the inclined return cylinder 120 as a heating source, and then the separated oil and gas enter the inner side of the catalytic filter box 201 through the gas pipe 210, and then go to step S4;

[0052] S4, flue gas filtration: After the oil gas enters the catalytic filter box 201, it passes through the dolomite catalyst in the catalytic box 202 to react, and the oil gas after the reaction and filtration becomes a sensible combustible gas, and then the combustible gas passes through the filter hole 208 and is led out through the air guide pipe 209 for separate use. After the pyrolysis and gasification of the garbage in the pyrolysis gasification furnace 104 is completed and highly carbonized, it goes to step S5;

[0053] S5, lifting and refueling: after the pyrolysis is completed, the cylinder 122 is started again to drive the conical net frame 110 to rise. After the conical net frame 110 rises to the top, the high-temperature carbonized garbage inside the pyrolysis gasification furnace 104 falls into the interior of the carbonization heating furnace 102 as a heating source. At this time, the igniter 121 is closed. During the rising process of the cylinder 122 at this time, the cylinder 122 will drive the arc pressure frame 206 to rise synchronously, so that the arc pressure frame 206 squeezes the pressure cross bar 205 to pull the catalyst box 202 out of the catalytic filter box 201. After the catalyst box 202 is moved out, the non-regenerated dolomite catalyst inside falls to the inner side of the receiving frame 214, and then the high-temperature heated catalyst enters the carbonization heating furnace 102 through the return material inclined pipe 215 as a heating source. After the cylinder 122 is lowered, the arc pressure frame 206 no longer squeezes the pressure cross bar 205, so that the catalyst box 202 is moved out of the spring 204 retracts to the inside of the catalytic filter box 201 under the elastic force of the arc pressure frame 206, and the top of the catalyst box 202 is pressed against and locked, and then the solenoid valve 213 is started to quantitatively add the dolomite catalyst in the storage barrel 212 into the inner side of the catalyst box 202 as a new catalyst material, and at the same time, the preheated garbage at the bottom of the material rotating plate 113 also falls to the top of the conical mesh frame 110 again. At this time, the carbon particles, carbonized garbage and high-temperature non-regenerative catalyst in the carbonization heating furnace 102 are used as heat sources to pyrolyze and gasify the garbage. At the same time, the carbon slag after combustion in the carbonization heating furnace 102 falls to the inside of the slag dropping base 101 through the slag leakage mesh groove 105. When the motor 106 drives the stirring rack 111 to rotate using the inner groove rotating rod 107, the arc push plate 108 pushes the carbon slag outward and discharges it from the slag dropping base 101, and at the same time, the stirring rack 111 turns the garbage to make it evenly heated.
