Problems solved by technology
The current resource utilization of industrial organic solid waste is mainly waste incineration for power generation or mixed combustion with coal-fired power plants for power generation, but there are problems such as low energy utilization efficiency and low level of resource utilization, especially the current cancellation of biomass power generation subsidies and Reduced, high energy consumption and low thermal power plants have been shut down one after another. How to improve energy utilization efficiency is an important way to solve the long-term development of waste incineration power plants and coal-fired power plants

Embodiment
[0016] like figure 1 As shown, an industrial organic solid waste heat dissipating and coal thermoconuclear coupling method is to break the general industrial organic solid waste after crushing, by magnetic selection first, the metal, the organic raw material after the metallo is passed through delivery. The device is delivered to the pyrolytic reactor for the pyrolysis reaction, and the metal sorted metal is directly sold, the pyrolysis generated by the pyrolysis is introduced into the combustion boiler by the ventilation or suction device to sufficient combustion reaction, and the pyrolysis carbon produced by the pyrolysis After entering the coal mixing machine and the coal mixed crushing, enter the combustion boiler for sufficient combustion reaction, and the high-temperature flue gas generated by combustion generates steam for thermoelectric bans, and finally enters the existing power plant flue gas treatment equipment to process the standard emissions.
[0017] Among them, the...

The invention discloses an industrial organic solid waste pyrolysis gasification and coal-fired combined heat and power generation coupling method. The method comprises the following steps: crushing industrial organic solid waste, and removing metal through magnetic separation; conveying the crushed and metal-removed raw materials to a pyrolysis reactor for a pyrolysis reaction; enabling the generated pyrolysis gas to enter a combustion boiler, enabling the generated pyrolytic carbon to enter a coal mill to be mixed with coal to be crushed and then enter the combustion boiler, and performing a sufficient combustion reaction; enabling the high-temperature flue gas generated by the combustion boiler to pass through the waste heat boiler to generate steam for combined heat and power generation, and then enabling the steam to enter the flue gas treatment equipment to be treated and discharged after reaching the standard. The industrial organic solid waste pyrolysis gasification and coal-fired combined heat and power generation are coupled, use of coal fossil fuel is saved, and the power generation efficiency of a coal-fired power plant is improved.
Description
Technical field [0001] The present invention relates to waste utilization techniques, and more particularly to an industrial organic solid waste heat dissociation and a coal thermocoupler coupling method. Background technique [0002] Comprehensive utilization of industrial solid waste is an important part of energy conservation and environmental strategic emerging industries. This is not only an important way to provide resource security for industrial and fast development, but also environmental pollution and safety hazards caused by industrial solid waste disposal and improper. Fundamental policy. The comprehensive utilization of industrial organic solid waste is the key to achieving an industrial transformation and upgrading, which not only makes urban domestic garbage as a resource to be fully utilized, but also has high environmental benefits and social benefits. The current use of industrial organic solid waste use is mainly garbage incineration power generation or blendin...
