Technical Field

The invention relates to a heat-carrying air source system of garbage dryers, belonging to the technical field of material drying.

Background

Aiming at the drying treatment of 'split-range garbage pyrolysis gasification + internal combustion power generation', double-helix drying devices are disclosed, and the device adopts a brand-new structural design and has the advantages of large heat transfer coefficient, high drying efficiency, garbage applicability and the like.

In order to avoid other reactions in the drying process of the garbage, the temperature in the drying process is generally controlled to be about 200 ℃, the double-helix garbage dryer is indirect heat exchange dryers, the heat-carrying gas of the double-helix garbage dryer can be replaced by tail gas of a generator, but the exhaust temperature of an internal combustion generator is generally 400 ℃ and 600 ℃, and therefore the double-helix garbage dryer needs to be subjected to temperature reduction treatment.

Disclosure of Invention

The invention aims to provide an heat-carrying air source system of a garbage dryer, which has the advantages of simple system, convenient operation, stable performance and the like.

A heat-carrying air source system for garbage dryer is composed of electric generator, SCR, fume baffle , blower, air side baffle , mixing cooler, dryer, and draught fan.

The heat-carrying air source system of the garbage dryer is characterized by comprising the following processes that after exhaust gas of an internal combustion generator is purified through SCR, parts are directly discharged, parts of flue gas enters a mixing cooling device to be mixed with air blown by a blower to be cooled, enters the dryer to finish heat exchange, and is led out by a draught fan to be discharged.
