Embodiment 1

[0033] A method of laser cracking and burning domestic waste to generate electricity, the specific process of processing domestic waste is as follows:

[0034]Household garbage composed of paper, plastic, fiber, metal and glass is aired to dry naturally, and then crushed by a four-axis garbage shredder. The rotation speed of the knife roller is 30r / min. Crushed material is collected and filtered in a plate and frame filter press, using hydraulic pressure, the working pressure of the plate and frame is 12MPa, the filtration pressure is 0.4MPa, the feed temperature is 20°C, and the hydraulic oil is first filtered with a 20μm filter. , water and oil enter the anhydrous treatment pool for treatment, and the solid waste is collected for use. The water and oil content in the solid waste is less than 1%; the solid waste is placed in an infrared heater, and nitrogen is introduced to remove the air in the heater. Turn on infrared rays, use short infrared rays with a wavelength of 5 μm,...

Embodiment 2

[0037] A method of laser cracking and burning domestic waste to generate electricity, the specific process of processing domestic waste is as follows:

[0038] Household garbage composed of paper, plastic, fiber, metal and glass is aired to dry naturally, and then crushed by a double-shaft garbage shredder with a knife roller rotating speed of 22r / min. Crushed material is collected and filtered in a plate and frame filter press, using hydraulic pressure, the working pressure of the plate and frame is 16MPa, the filtration pressure is 0.3MPa, the feed temperature is 40°C, and the hydraulic oil is first filtered with a 20μm filter. , water and oil enter the anhydrous treatment pool for treatment, and the solid waste is collected for use. The water and oil content in the solid waste is less than 1%; the solid waste is placed in an infrared heater, and nitrogen is introduced to remove the air in the heater. Turn on infrared rays, use long infrared rays with a wavelength of 10 μm, ...

Embodiment 3

[0041] A method of laser cracking and burning domestic waste to generate electricity, the specific process of processing domestic waste is as follows:

[0042] Household garbage composed of paper, plastic, fiber, metal and glass is aired to dry naturally, and then crushed with a four-axis garbage shredder. The rotation speed of the knife roller is 25r / min. Crushed material is collected and filtered in a plate and frame filter press, using hydraulic pressure, the working pressure of the plate and frame is 18MPa, the filtration pressure is 0.2MPa, the feed temperature is 50°C, and the hydraulic oil is first filtered with a 20μm filter. , water and oil enter the anhydrous treatment pool for treatment, and the solid waste is collected for use. The water and oil content in the solid waste is less than 1%; the solid waste is placed in an infrared heater, and nitrogen is introduced to remove the air in the heater. Turn on infrared rays, use mid-infrared rays with a wavelength of 6 μm...

Abstract

The invention belongs to the technical field of garbage treatment, and provides a method for generating electricity by combusting domestic garbage through laser pyrolysis. The method comprises the steps that domestic garbage is smashed, pressed and filtered, and water and grease are recycled; solid garbage is subjected to infrared heating and laser treatment to be decomposed, hydrogen, carbon monoxide, methane and other combustible gas are generated, and coke, carbon blank and other solids are left; and combustible gas is fed into a combustion chamber to be combusted for steam power generationor heating through a heating boiler. Compared with a traditional method, the combustible gas obtained through the treatment method is combusted in a clean mode, secondary pollution and stink problemsare greatly relieved, meanwhile, the whole process is low in energy consumption, the labor cost is low, the garbage utilization rate s high, the additional value is high, and remarkable environmentalprotection advantages and good economic advantages are obtained.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment and provides a method for generating electricity by laser cracking and burning household garbage. Background technique [0002] Household garbage is an accompaniment to human production and life, and a universal problem faced by human beings, which is related to the coordinated development of population, resources, and the environment. With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the output of urban domestic waste is increasing day by day. These garbage not only occupy a large amount of land and destroy the urban landscape, but also cause continuous pollution to the environment on which human beings live, and thus pose a threat to human health. How to properly dispose of domestic waste and realize waste reduction, recycling, harmlessness and industrialization has become an urgent probl...
