Abstract

The invention discloses a garbage drying device. The garbage drying device comprises a feed port, a discharge port, an inlet moisture meter and an outlet moisture meter; moist garbage enters a fire grate in a drying chamber from the feed port, and moves along with the fire grate; intake ports are uniformly formed below the fire grate; hot smoke sprayed by the intake ports is used for drying the garbage, and is conveyed into the drying chamber by a tail gas pipe; and the flow is controlled by the openness of intake port valves. The hot smoke and water vapor evaporated from the garbage are discharged by an exhaust port. The garbage drying device uses the tail gas afterheat of a garbage combustion boiler without excessively consuming other heat for detecting the water content of the fed and discharged garbage in real time to prevent combustion of the garbage in the drying chamber, returns and controls the water content of the garbage in real time to control the openness of the valves to control the intake quantity of tail gas, improves the utilization efficiency of the tail gas, and adopts a multi-layer fire grate overturning mechanism to deeply feed the tail gas into the garbage layer to achieve good drying effect.

Description

technical field

[0001] The invention belongs to the field of garbage treatment devices, and in particular relates to a garbage drying device. Background technique

[0002] With the rapid growth of urban population in China today, the dramatic increase of municipal solid waste has brought many problems. Advocate the "3R" concept, that is, waste reduction (Reduce), waste recycling (Reuse) and waste recycling (Recycle) play an extremely important role in waste disposal. The trend of waste disposal is to incinerate it, or make it into recycled coal through technical means. Studies have shown that primary domestic waste contains a large amount of water, and the presence of such a large amount of water makes the effective drying of waste before incineration and regeneration to remove the water contained in it plays a vital role in the entire waste treatment process.

[0003] The current drying technology needs to consume a lot of energy, which consumes a lot of energy and causes...
