[0048] The pyrolysis gasification waste treatment system 10 includes a waste drying room 11 , at least two pyrolysis furnaces 12 , a secondary combustion chamber, a heat exchanger 13 and a first control system 18 .

[0049] Among them, the garbage drying room 11 is used for drying garbage, and the pyrolysis furnace 12 has a feeding part and a combustible gas discharge part. And the combustion outlet, the combustion inlet is communicated with the combustible gas discharge parts of at least two pyrolysis ...

Embodiment 2

[0058] This embodiment provides a pyrolysis gasification waste treatment system 20, which is based on the pyrolysis gasification waste treatment system 10, please refer to figure 2 , figure 2 A schematic diagram of the pyrolysis gasification waste treatment system 20 in this embodiment is shown.

[0059] The pyrolysis gasification waste treatment system 20 also includes a second temperature sensor 22, a second control system 23 and the first temperature sensor 21 having the same number as the pyrolysis furnace 12, and a plurality of first temperature sensors 21 are respectively arranged in the pyrolysis In the furnace 12 , the first temperature sensors 21 respectively sense the furnace temperature of the corresponding pyrolysis furnace 12 .

[0060] When the first control system 18 receives a signal that the temperature sensed by the first temperature sensor 21 does not reach the first preset temperature, it controls the combustion air nozzle in the pyrolysis furnace 12 to ...

Embodiment 3

[0064] Please refer to image 3 , image 3 A schematic diagram of the pyrolysis gasification waste treatment system 30 provided in this embodiment is shown.

[0065] Based on the pyrolysis and gasification garbage treatment system 10, the pyrolysis and gasification garbage treatment system 30 also includes a neutralization atomization device 31 and a bag filter 32, so as to treat the gas discharged from the combustion furnace 15 and further reduce the pollution to the atmosphere .

[0066] The neutralization and atomization device 31 is connected to the gas outlet of the heat exchanger 13, and the neutralization and atomization device 31 is used to treat the harmful gas discharged from the secondary combustion chamber, specifically, through the neutralization and atomization device 31, the smoke passes through the mist The rapid cooling and neutralization of chemical water can effectively prevent the regeneration of dioxins, and make the flue gas go through preliminary deaci...

Abstract

The invention discloses a pyrolysis gasification garbage treatment system and a garbage treatment system, and relates to the field of garbage treatment. The pyrolysis gasification garbage treatment system comprises a garbage drying room, at least two pyrolysis ovens, a secondary combustion chamber and a heat exchanger, each pyrolysis oven comprises a feeding portion and a combustible gas discharging portion, garbage is transferred into the pyrolysis ovens by the feeding portions and subjected to pyrolysis gasification, the secondary combustion chamber comprises a combustion inlet and a combustion outlet, the combustion inlet is communicated with the combustible gas discharging portions of the pyrolysis ovens, a gas inlet of the heat exchanger is connected with the combustion outlet, a heat exchange pipeline of the heat exchanger is connected with the garbage drying room, and heat discharged by the combustible gas discharging portions is converted into heat for drying the garbage by the garbage drying room through the heat exchanger. The pyrolysis gasification garbage treatment system is high in pyrolysis gasification efficiency, the purification efficiency of poisonous gas is improved through the secondary combustion chamber, and energy consumption of pyrolysis gasification is reduced.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a pyrolysis gasification garbage treatment system and a garbage treatment system. Background technique [0002] With the rapid development of my country's economy, the output of municipal solid waste has also maintained a rapid growth trend, and people's attention to environmental protection issues has also continued to rise. [0003] Garbage pyrolysis and gasification refers to the process of breaking the macromolecules of organic components in garbage to produce small molecule gases, tar and residues under the condition of no oxygen or oxygen deficiency. Garbage pyrolysis gasification technology not only realizes the harmlessness, reduction and recycling of garbage, but also effectively overcomes the problem of dioxin pollution caused by garbage incineration, so it has become a garbage treatment technology with great development prospects. [0004] In the existing garbage trea...
