The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model
Limitation.
Drying garbage system 100 below with reference to Fig. 1-Fig. 6 description according to the utility model embodiment, drying garbage system
100 for being dried the higher rubbish of moisture content, so that the moisture content of rubbish reaches the requirement of environmental protection treatment, improves
Refuse thermal value enters rubbish more stable when furnace burns, and then improves the generated energy after garbage disposal, economic benefit.
As shown in figs 1 to 6, according to the drying garbage system 100 of the utility model embodiment, comprising: high-temperature gas is produced
System 30, dry generating system 1 and exhaust treatment system 50.
High-temperature gas preparation system 30 is for producing high-temperature gas, and the hot-gas temperature after producing is 200 DEG C~220
DEG C, high-temperature gas can come into full contact with after being passed through dry generating system 1 with the rubbish in dry generating system 1, so that in rubbish
Moisture is fully evaporated, and then is effectively reduced the moisture content in rubbish.
It should be noted that the temperature of high-temperature gas cannot be below 200 to guarantee that high-temperature gas sufficiently exchanges heat with rubbish
℃；The temperature of high-temperature gas is unsuitable excessively high, and such as when the temperature of high-temperature gas is higher than 360 DEG C, high-temperature gas and rubbish contact are again
Plastics clot is easily caused, and the volatile phenol in rubbish is easy to cause largely to overflow, has not only increased vent gas treatment difficulty, but also lead to rubbish
Rubbish calorific value reduces.The temperature of high-temperature gas is controlled in suitable range as a result, advantageously ensures that the benefit of garbage disposal.
As shown in Figure 1, dry generating system 1 includes flue gas drying machine and wind-distributing pipe, flue gas drying machine is to carry out to rubbish
Rubbish to be processed can be placed in the shell 20 of flue gas drying machine in order to be dried by the device of drying process.
