High garbage dewatering efficiency, as shown in Figure 5.
In order to equipment arrangement reasonability and save floor occupying area, second rubbish air-dry cylinder 31 be arranged at first rubbish
The lower section of air-dried cylinder 30, both are be arranged in parallel using fixed support about 38.Such first rubbish air-dries the rubbish of cylinder 30 and second
The traffic direction of low temperature dry-air blast is identical in air-dried cylinder 31, air-dries the rubbish of cylinder 30 and second from first rubbish and air-dries what cylinder 31 passed through
The band moisture bearing gas for absorbing moisture in rubbish are discharged from gas discharge outlet 36.First rubbish air-dries the rubbish wind of cylinder 30 and second
Rubbish direction of propulsion in dry cylinder 31 is then conversely, rubbish sequentially passes through the first rubbish from after the entrance of charging aperture 33 air-dries cylinder 30 and the
Two rubbish air-dry cylinder 31 and finally discharge from rubbish discharging opening 37.
The rubbish air-dries processing system also includes that rubbish pre-processes reducing mechanism and rubbish feeding device.The rubbish pretreatment
Reducing mechanism, for the bale broken of rubbish, sorting and pulverization process；The rubbish feeding device includes waste transport mechanism 39, the rubbish
The import of rubbish transmission mechanism 39 be connected with the outlet of rubbish pretreatment reducing mechanism, the outlet of the waste transport mechanism 39 and this
First rubbish air-dries the charging aperture 33 of cylinder 30 and connects.
The rubbish for air-drying processing system using above-mentioned rubbish air-dries processing method and comprises the steps：
(1) with high-temperature tail gas as hot air source, natural wind be mend wind, by the low temperature dry-air blast device for making produce low temperature do
Wind.
Wherein, the hot air source is entered from the hot blast air supply line 15, respectively in the air distribution outlet 8 of the first air distribution outlet 7 and second
Place allocates into from first air distribution and is in charge of the air distribution for being in charge of discharge with the second air distribution, takes off subsequently into after the cold-hot wind exchange mechanism 11
Water is discharged from the hot air outlet；The natural wind is entered from the benefit wind air inlet 1, and through the cold wind of the cooling exchanger 12 wind is mended
After passage, from the benefit wind air outlet 2 cold air inlet 3 is discharged into, subsequently into the cold-hot wind exchange mechanism 11 in it is cold
Wind pipeline, then the air distribution air inlet 5 of the cooling exchanger 12 is entered after discharging from the cold wind air outlet 4, exchange through the cooling
Device 12 with from air distribution air outlet 6 being discharged into first air distribution after wind chilling channel and be in charge of to be in charge of with the second air distribution.
Further on the basis of being in charge of including the 3rd air distribution outlet 9 and the 3rd air distribution, from doing that the hot air outlet is discharged
Wind is entered in the blending bin 19, is allocated the air distribution for being in charge of discharge from the 3rd air distribution at the 3rd air distribution outlet 9 and is mixed also into this
In mould assembling 19, the dry-air blast and air distribution discharge final obtained low temperature dry-air blast after mixing in the blending bin 19.
Specifically cold-hot wind air distribution ratio is：Hot blast and the air distribution ratio of air distribution are 1 at first air distribution outlet：1～1.5, second matches somebody with somebody
Hot blast and the air distribution ratio of air distribution are 1 at air port：2～2.7, the air distribution ratio of hot blast and air distribution is 1 at the 3rd air distribution outlet：2.5～
3.5。
(2) the low temperature dry-air blast produced using step (1) is air-dried by the rubbish air drying treatment device to garbage raw material
Process, dry rubbish is obtained.
Wherein, the low temperature dry-air blast air-dries the direction of propulsion phase of the traffic direction in cylinder 30 and its rubbish in first rubbish
Together, the low temperature dry-air blast is contrary with the direction of propulsion of its rubbish in the traffic direction that second rubbish is air-dried in cylinder 31.
The present invention introduces high-temperature tail gas using low-temperature air-drying device for making, allocates natural wind, and the high-temperature tail gas are dropped
Temperature is processed, and to the moisture removal in natural wind and high-temperature tail gas, realizes producing for low temperature dry-air blast, also by low temperature dry-air blast to rubbish
Rubbish air-dries the dehydration of rubbish in cylinder and air-dries, and realizes the air-dried process of rubbish, can realize being more than moisture content the wind of 45% wet refuse
Dry-cure, final prepared moisture content is 8～15% dry rubbish.
It is contour that the air-dried processing system of rubbish of the present invention can be used for Fresh Life rubbish, medical waste, old rubbish or sludge
The air-dried process of humidity rubbish, the high-temperature tail gas by the use of incinerator discharge make discarded heat energy obtain resource as hot air source
Change and recycle, energy saving can realize new refuse to show up i.e. and be dehydrated again, without stacking alcoholization, do not produce stench, do not analyse
Go out percolate, deducted the processing links of percolate, improve the working environment of destructor plant, the rubbish of mummification is not only just
In storage transport, and the landfill soil after dried disinfecting backfills again dump pit, can thoroughly solve water air pollution hidden danger, energy-saving ring
Protect.
The above, is only presently preferred embodiments of the present invention, and any pro forma restriction is not made to the present invention, this
Art personnel make a little simple modification, equivalent variations or modification using the technology contents of the disclosure above, all fall within this
In bright protection domain.
