Energy-saving green garbage pyrolysis cracking system and cracking method thereof

Abstract

The invention relates to an energy-saving green garbage pyrolysis cracking system and a cracking method thereof. The cracking system comprises a pyrolysis bin, a feeding pipe is fixedly arranged on one side of the upper end of the pyrolysis bin, a storage bin is fixedly arranged at the upper end of the feeding pipe, a feeding opening is fixedly formed in one side of the upper end of the storage bin, and a rotating rod is movably arranged between the feeding pipe and the storage bin through a bearing. By means of a slow falling mechanism, garbage entering the pyrolysis bin can slowly fall, so that after the crushed garbage enters from the feeding pipe at the top of the pyrolysis bin, the garbage is dried and pyrolyzed in the process of slowly falling and moving along a plate from top to bottom by virtue of the dead weight of the garbage, therefore, the garbage can be effectively prevented from being accumulated at the lower end in the pyrolysis bin to affect the pyrolysis effect, meanwhile, steam is fully utilized as kinetic energy to be used for generating electricity and pushing all mechanical parts of the device to work, and the energy-saving and environment-friendly effects can be achieved.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to an energy-saving green garbage pyrolysis cracking system and a cracking method thereof. Background technique [0002] With the update and development of waste treatment technology, it is gradually optimized, from landfill at the beginning, to biomass composting, to incineration with the best reduction effect, and finally to pyrolysis gasification technology, every step of technology update Both lead the development direction of the industry. Pyrolysis and incineration are two completely different processes. Incineration is an exothermic process, while pyrolysis needs to absorb a large amount of heat. The main products of incineration are carbon dioxide and water, while pyrolysis The main products are flammable low-molecular compounds: gaseous hydrogen, methane, carbon monoxide; liquid methanol, acetone, acetic acid, acetaldehyde and other organic substances, tar, solvent oil, et...

AI Technical Summary

Problems solved by technology

[0004] 1. When the current garbage pyrolysis cracking system is in use, the crushed garbage is directly put into the pyrolysis bin. When a lot of garbage is put in, the garbage directly falls and accumulates at the lower end of the pyrolysis bin and the pyrolyzed coke and carbon black If they are mixed together, it is easy to cause uneven heating of the garbage and it is difficult to complete the reaction, which will affect the pyrolysis efficiency and quality of the device, and in order to prevent this phenomenon, the furnace body is generally designed to be larger and smaller. Large design is difficult to heat up and occupies a large area;

[0005] 2. When the current garbage pyrolysis and cracking system is in use, the waste gas generated after pyrolysis is often heated to urea for re-burning, so that harmful gases such as dioxin and tar are re-burned, so that harmful gases are degraded and become non-toxic Harmless gas; however, the current urea spraying structure lacks linkage and cannot automatically control the spraying amount of urea according to the amount of exhaust gas, so it is easy to cause insufficient urea spraying, insufficient treatment of harmful gases, or excessive urea spraying, resulting in waste of urea occur, thus easily causing unnecessary waste, which is not environmentally friendly;

[0006] 3. When the current garbage pyrolysis and cracking system is in use, the high-temperature gas generated after combustion will be used to gasify water to generate steam for power generation to recover energy, and at the same time provide power for the mechanical equipment of the entire system, but it is necessary The thermal energy of the high-temperature gas is converted into steam energy, and then the steam energy is converted into mechanical energy to make the generator rotate, and then the electric energy generated by the generator is converted into mechanical energy to provide power for the mechanical equipment of the device through operations such as inverter and voltage transformation. The energy conversion steps are relatively cumbersome, and it is easy to waste energy, which is not environmentally friendly
