As shown in fig. 1, the garbage disposal system in this embodiment includes: crushing device, mummification device, sorting unit, pyrolysis device and combustion reactor. Wherein, the breaker can select for use the coarse crusher for carry out preliminary breakage to the rubbish of handling, handle into the rubbish that the particle diameter is less than default dimension with it, be convenient for carry on follow-up other processing procedures. The drying device is used for drying the garbage after the primary crushing. The sorting device is used for sorting out metals in the garbage, facilitating subsequent pyrolysis treatment and screening part of combustible garbage in the dried garbage. The pyrolysis device is used for carrying out pyrolysis treatment on part of the garbage to generate pyrolysis gas and pyrolysis slag. And the pyrolysis gas and/or the pyrolysis slag are conveyed to a combustion reactor to be combusted to generate high-temperature flue gas. In this embodiment, the heat sources used by the drying device and the pyrolysis device are high-temperature flue gas generated by combustion in the combustion reactor.
The high-temperature flue gas exchanges heat when passing through the pyrolysis device or the drying device, the temperature is reduced, and the high-temperature flue gas is discharged only by further treatment. Therefore, in the garbage disposal system of this embodiment, a flue gas purification device is further provided for purifying the high-temperature flue gas after heat exchange flowing out of the pyrolysis device and the drying device.
In addition, in this embodiment, the garbage disposal system further comprises a garbage repository for storing the garbage to be disposed.
In addition, in order to improve the efficiency of pyrolysis, the sorting device can also carry out crushing treatment on the garbage and further screen combustible garbage in the garbage to be treated. For example, in the case of household waste, it can be classified into combustible waste and other waste. The combustible garbage can be used for preparing solid recovered fuel, and other garbage is mainly non-combustible inorganic matters and metals.
Specifically, in this embodiment, the sorting apparatus includes: the device comprises a magnetic separator, a screening system, a winnowing machine, a fine crusher, a light garbage storage bin, a heavy garbage storage bin and belt conveyors for conveying materials among various devices. When the magnetic separator is used, the dried garbage is conveyed to a magnetic separator by a belt conveyor, and a part of magnetic metals, such as iron, nickel and the like, carried in the garbage are separated. The waste is then conveyed to a screening system where it is screened into oversize waste of larger particles and undersize waste of smaller particles.
And respectively carrying out magnetic separation treatment on the oversize garbage and the undersize garbage by using a magnetic separator for one time, and further separating out the magnetic metals in the oversize garbage and the undersize garbage. And then, wind power separation is respectively carried out on the oversize garbage and the undersize garbage by using a wind separator. It should be noted that the power of the winnowing machines used by the two machines is different because the particle size of the waste on the screen is larger than that of the waste under the screen. The power of the winnowing machine used for the garbage on the screen is larger than that of the winnowing machine used for the garbage under the screen.
After the air separation, the garbage on the screen is divided into light garbage and heavy garbage, and the garbage under the screen is divided into light garbage and heavy garbage. The light garbage is the combustible garbage and comprises organic matters such as wood and straw and combustible inorganic matters such as plastics and rubber; the heavy garbage and the magnetic metal are the above incombustible garbage and comprise metal, stone, tile and the like.
The light garbage can be further crushed by a fine crusher so as to be convenient for subsequent pyrolysis treatment. And finally, conveying the light garbage to a light garbage storage bin, and conveying the heavy garbage to a heavy garbage storage bin. The particle size of the garbage crushed by the coarse crusher and the fine crusher can be set according to actual requirements, and is not described herein again.
In other embodiments, other existing mechanical devices can be used to separate the garbage into combustible garbage and non-combustible garbage, and further description is omitted here.
The sorting operation classifies the garbage, and is convenient for subsequent targeted treatment. For example, the metal can be recycled, the heavy garbage can be used as building materials, and the light garbage, namely combustible garbage can be used for preparing solid recovery fuel and can also be used for carrying out pyrolysis treatment to generate pyrolysis gas and pyrolysis slag. Of course, if the separation operation is performed, part of the heavy garbage contains combustible garbage, and the part of the heavy garbage can also be sent into the pyrolysis device for pyrolysis treatment, so that the combustible garbage in the garbage can be fully utilized.
Specifically, in this embodiment, the pyrolysis apparatus is a horizontal pyrolysis furnace in this embodiment, and includes a furnace body for performing pyrolysis reactions, the furnace body having a waste input port, a slag discharge port, and an exhaust port. In addition, in order to improve the pyrolysis efficiency, a heat exchange device is arranged on the outer side surface of the furnace body, one end of the heat exchange device is connected with a pipeline for conveying high-temperature flue gas, the other end of the heat exchange device is connected with a drying device, the furnace body is heated through the heat of the high-temperature flue gas, and the pyrolysis efficiency is further improved. In one embodiment, the heat exchange device is a heating pipeline which is coated on the outer side surface of the furnace body, one end of the heating pipeline is connected with a pipeline for conveying high-temperature flue gas, and the furnace body is heated by the high-temperature flue gas, so that the pyrolysis efficiency is improved; the other end of the heating pipeline is connected with a drying device.
The garbage is pyrolyzed in a horizontal pyrolyzing furnace to generate pyrolysis gas and pyrolysis slag. The pyrolysis slag is discharged from a slag discharge port, and the main components of the pyrolysis slag are tar and carbon black which can be used as industrial raw materials. The pyrolysis gas and the pyrolysis slag can be input into a combustion reactor together to be combusted to generate high-temperature flue gas.
Specifically, in this embodiment, the drying device may adopt a high-temperature flue gas drying apparatus, and the high-temperature flue gas is used to dry the garbage to be treated. The rear end of the sorting device is also provided with a solid recovery fuel storage, and one end of the solid recovery fuel storage is connected with the sorting device through a conveying belt. The solid recovery fuel output by the sorting device is stored in a solid recovery fuel storage. The high-temperature flue gas after heat exchange in the drying device and the pyrolysis device finally flows into the flue gas purification device.
It should be noted that, the light garbage is partially directly made into the solid recovery fuel, and partially continues to be pyrolyzed, so in practical application, the light garbage obtained by sorting needs to be distributed, a certain weight or volume of light garbage can be preset for pyrolysis treatment, and a certain weight or volume of light garbage can be preset for making the solid recovery fuel. Because the pyrolysis treatment, the drying treatment and the preparation of the solid recovered fuel are continuous operation processes and need to be added continuously, when the light garbage is more, the pyrolysis treatment, the drying treatment and the preparation of the solid recovered fuel can be carried out synchronously, and only enough high-temperature smoke is needed to be ensured during the drying treatment. In addition, the high-temperature flue gas after heat exchange between the pyrolysis device and the drying device is purified by the flue gas purification device and then discharged.

And then, wind power separation is respectively carried out on the oversize garbage and the undersize garbage by utilizing a winnowing machine. It should be noted that the power of the winnowing machines used by the two machines is different because the particle size of the waste on the screen is larger than that of the waste under the screen. The power of the winnowing machine used for the garbage on the screen is larger than that of the winnowing machine used for the garbage under the screen. After the air separation, the garbage on the screen is divided into light garbage and heavy garbage, and the garbage under the screen is divided into light garbage and heavy garbage. The light garbage is the combustible garbage and comprises organic matters such as wood and straw and combustible inorganic matters such as plastics and rubber; the heavy garbage and the magnetic metal are the above incombustible garbage and comprise metal, stone, tile and the like.

In the embodiment, the high-temperature flue gas generated by the combustion of the pyrolysis gas is firstly input into the pyrolysis device to supply heat to the pyrolysis device, and then input into the drying device to dry the garbage, so that the heat of the high-temperature flue gas is fully utilized.
And finally, the high-temperature flue gas which flows out of the drying device and exchanges heat can be discharged only after being purified.
It should be noted that, in this embodiment, a sorting device capable of screening combustible waste in the waste to be processed is provided, and the combustible waste screened by the sorting device is pyrolyzed to improve the processing efficiency.
