Description

Technical Field

[0001] The present invention relates to the technical field of energy storage and solid waste treatment, and in particular to a peak regulation system coupled with surplus energy consumption and solid waste treatment. Background Art

[0002] Using solid waste to prepare gas is an effective means of energy recovery and environmental protection, especially in valley power peak regulation. By converting solid waste into combustible gas, it can not only reduce waste accumulation and environmental pollution, but also provide a flexible energy supplement, which helps the power grid store energy during low demand periods and release energy during peak periods, thereby achieving stable operation of the power system.

[0003] At present, most pyrolysis equipment uses solar thermal coupled biomass pyrolysis reaction devices. For example, patent CN116240040A uses self-driven solar thermal to pyrolyze biomass, which does not completely rely on solar energy to pyrolyze biomass.

[0004] In addition to the solar thermal coupled biomass pyrolysis reaction device, vertical microwave pyrolysis can also be used to increase the gas product. For example, in patent CN 116162498A, the products obtained by microwave pyrolysis are separated vertically into solid and liquid under an inert atmosphere to increase the gas production. In addition, "Experimental Study and Mechanistic Analysis of the Preparation of Hydrogen-Rich Gas by Catalytic Pyrolysis of Corn Straw" discloses a scheme to improve the photothermal pyrolysis process by increasing the pyrolysis temperature and adding catalysts.

[0007] (2) The existing vertical microwave pyrolysis method for preparing gas from solid waste adopts a one-time pyrolysis method, which requires the solid waste to be pyrolyzed to 1000-1100°C for complete pyrolysis.

[0008] In view of this, how to provide a pyrolysis device that can partially or completely solve the above-mentioned defects is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] In this embodiment, a pretreatment chamber 7 is also included. The heat absorber can supply heat to the pretreatment chamber 7. The pretreatment chamber 7 can preheat the solid waste at a temperature of 100-200°C. The preheated solid waste is transported to the gasifier 2 through the first crawler conveyor 12. The function of the pretreatment chamber 7 is to remove moisture from the solid waste and turn the solid waste into a dry state to facilitate subsequent pyrolysis.

[0044] The gasifier 2 comprises: a furnace body 201, a feed port is provided on one side of the furnace body 201, and the feed port is connected to the first crawler transmission device 12; a stirring device 202, and the stirring device 202 is arranged at the furnace bottom of the gasifier 2; a heating component 203, and the heating component 203 is arranged on the inner surface of the gasifier 2 and is heated by a heat absorber; an air intake pipe 204, and the air intake pipe 204 is connected to the furnace body 201, and is used to transport inert gas and carbon dioxide gas into the furnace body 201; solid waste is pyrolyzed into primary fuel gas, hot fuel oil and pyrolytic coke in the furnace body 201, and the primary fuel gas, hot fuel oil and pyrolytic coke are distributed in sequence from top to bottom; a first gas collection pipe 8 is provided in the area of ​​the furnace body 201 corresponding to the distribution of the primary fuel gas, and the first gas collection pipe 8 is connected to the gas storage tank 3, and a tar collection mechanism is provided in the area of ​​the furnace body 201 corresponding to the distribution of the hot fuel oil and the pyrolytic coke, and the tar collection mechanism is connected to the tar storage mechanism.

[0045] The tar storage mechanism includes a pyrolysis coke storage chamber 9 and an oil storage tank 10, and the tar collection mechanism includes an oil outlet pipeline 11 and a second crawler conveyor 13.

[0046] In this embodiment, a heat collecting mechanism 14 is also included, and the heat collecting end of the heat collecting mechanism 14 (the heat collecting mechanism 14 can be a heat exchanger and heat storage filled with heat exchange medium, and the heat collecting end is the contact end between the heat exchange medium and the following structure, and the heat collecting mechanism 14 can be any device that can exchange heat with the following structure, which is not limited here) is connected to the first gas collection pipeline 8 and / or the oil outlet pipeline 11 and / or the second crawler transmission device 13, and is used to collect the heat energy of the primary gas, hot oil and pyrolysis coke.

In some other embodiments, the pyrolysis oil and pyrolysis coke that are easy to exchange heat can also be input into the heat collecting mechanism 14 with a large heat exchange chamber, and then sent to the corresponding storage mechanism after heat exchange.

[0047] In this embodiment, an air intake regulating device is provided on the air intake pipe 204, and the air intake regulating device is used to adjust the ratio of the inert gas and the carbon dioxide gas entering the furnace body 201. Specifically, the inert gas and the carbon dioxide are loaded by different gas cylinders, respectively, and a flow valve can be set at the outlet of the gas cylinder, and the air intake regulating device uniformly regulates the air intake of the two to change the atmosphere in the furnace. A good atmosphere in the furnace can ensure sufficient pyrolysis of solid waste, improve the gas conversion rate and the overall power generation efficiency.

[0048] In this embodiment, a control center is also included. The microwave pyrolysis device 4 has a gravity sensor. The control center is connected to the gravity sensor in communication. The gravity sensor can monitor the weight of the hot oil and pyrolysis coke in the microwave pyrolysis device 4 and send it to the control center. The control center controls the thermal power generator set 6 to distribute power to the microwave pyrolysis device 4 according to the weight of the hot oil and pyrolysis coke. If the thermal power generator set 6 has redundant power, it supplies power to the gasifier 2 and / or the pretreatment chamber 7 and generates heat energy. A light radiation sensor is arranged on the solar concentrating tower 1. The light radiation sensor is connected to the control center in communication. When the light intensity is sufficient, the heat collection mechanism 14 does not need to supply heat to the gasifier 2 or the pretreatment chamber 7. When the light intensity is insufficient, the heat collection mechanism 14 supplies heat to the gasifier 2 or the pretreatment chamber 7 to maintain the pyrolysis function of the gasifier 2 and the preheating and drying functions of the pretreatment chamber 7.

[0049] In this embodiment, a fuel cell station 5 is also included, and the gas storage tank 3 can deliver primary gas and secondary gas to the fuel cell station 5. During peak hours of electricity consumption, the primary gas and secondary gas are fully burned in the fuel cell station 5 to generate water vapor to drive the steam turbine to generate electricity.

[0050] The specific working process is as follows:

[0051] During the day, the solar concentrating tower 1 absorbs solar energy through the heat absorber and generates heat. The solid waste is first sent to the pretreatment chamber 7, and the heat absorber provides heat to the pretreatment chamber 7 to generate a preheating temperature of 100-200°C, evaporating the water in the solid waste, and the solid waste is dried. The dried solid waste is transported to the gasifier 2 by the first crawler transport device.

[0052] The absorber supplies heat to the gasifier 2, and the gasifier 2 performs primary pyrolysis on the solid waste at a temperature of 500°C. During the pyrolysis process, the stirring device 202 is used to ensure the uniformity of pyrolysis. The pyrolysis time is about 1 hour. The solid waste after pyrolysis becomes primary gas, hot oil and pyrolysis coke, wherein the primary gas is at the top layer, the hot oil is in the middle layer, and the pyrolysis coke is at the bottom layer. The primary gas is directly collected into the gas storage tank 3 through the first gas collection pipeline 8, and the hot oil and pyrolysis coke are collected into the oil storage tank 10 and the pyrolysis coke storage chamber 9 respectively. During the transfer of the hot oil and pyrolysis coke to the corresponding collection device, the primary gas, hot oil and pyrolysis coke still have a temperature of more than 400°C, and the heat collection end of the heat collection mechanism 14 collects the heat of the primary gas, hot oil and pyrolysis coke by heat exchange.

[0053] At night, the power consumption is greatly reduced, and the thermal power generation unit 6 is forced to reduce the load. In order to ensure that the thermal power generation unit 6 maintains a safe load, the hot fuel oil and the pyrolysis coke are mixed, and the mixing ratio is not limited. The mixed hot fuel oil and pyrolysis coke are placed in the microwave pyrolysis device 4, and the thermal power generation unit 6 supplies redundant power to the microwave pyrolysis device 4, and the hot fuel oil and pyrolysis coke are pyrolyzed at a temperature of 1000°C, and the pyrolysis time is about 0.5 hours. The pyrolysis coke and the hot fuel oil are completely pyrolyzed to form secondary fuel gas, which is collected into the gas storage tank 3 through the second gas collection pipeline 15. The temperature of the secondary fuel gas is still above 900°C, and the heat collection end of the heat collection mechanism 14 collects the heat of the secondary fuel gas by heat exchange.

[0054] During peak electricity consumption periods, the gas is transported to the fuel cell station 5 through the gas storage tank 3 for power generation, thereby reducing the load of the thermal power generation components and achieving the valley power peak regulation function.

[0055] In the above process, when the light intensity is sufficient, the heat collecting mechanism 14 does not need to supply heat to the gasifier 2 or the pretreatment chamber 7; when the light intensity is insufficient, the heat collecting mechanism 14 supplies heat to the gasifier 2 or the pretreatment chamber 7 to maintain the pyrolysis function of the gasifier 2 and the preheating and drying functions of the pretreatment chamber 7, thereby making full use of the thermal energy storage of the heat collecting mechanism 14 and the thermal energy storage generated by the solar concentrating tower 1.

[0056] In the above process, since the solar concentrating tower 1 cannot work at night, in addition to the heat collecting mechanism 14 supplying heat to the gasifier 2 and the pretreatment chamber 7, the redundant power of the thermal power generator set 6 can also be used to supply electricity and heat to the gasifier 2 and the pretreatment chamber 7, making full use of valley electricity consumption.

[0057] The total time required for complete pyrolysis of solid waste using this embodiment is 1.5 hours, while the total time required for complete pyrolysis of solid waste using the traditional one-time microwave pyrolysis method is more than 2 hours. Compared with the traditional one-time microwave pyrolysis method, the present application not only shortens the pyrolysis time, but also reduces the pyrolysis energy consumption.

[0058] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0059] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
