Solid waste rotary furnace waste heat recycling device

Abstract

The invention discloses a solid waste rotary furnace waste heat recycling device. The solid waste rotary furnace waste heat recycling device comprises a furnace body, a smoke pipeline and a material collecting pipeline. An annular water barrel is arranged at the outer ring of the furnace body. A water inlet and an air outlet are formed in the upper end of the annular water barrel. A water outlet is formed in the lower end of the annular water barrel. The annular water barrel is located at a base at the lower end. The furnace body is tilted horizontally at a certain angle. The smoke pipeline and the material collecting pipeline are arranged at the uptrend end of the furnace body. The smoke pipeline is bent upwards, and is connected with a smoke waste heat recycling device. The smoke pipeline extends into the smoke waste heat recycling device. The smoke waste heat recycling device comprises an outer chimney, a water pipeline arranged downwards in the chimney spirally, and a spraying headarranged above the water pipeline. The water inlet end of the water pipeline is at the upper end of the chimney. The water outlet end of the water pipeline is at the lower end of the chimney. The bottom end of the chimney is inclined, and a notch used for discharging slurry is formed in the lower end of the chimney.

Description

technical field [0001] The invention relates to the field of waste heat recovery devices, in particular to a solid waste rotary furnace waste heat recovery device. Background technique [0002] With the increasingly prominent energy and environmental issues, how to use energy efficiently, recover various waste heat and reduce environmental pollution is the focus of attention. There is also a lot of heat in the solid material produced by production and the smoke produced by rotary kiln calcination. Heat recovery is an important way to reduce process energy consumption and improve energy utilization efficiency. However, the solid waste rotary kiln used in the prior art The energy utilization efficiency of the waste heat recovery device is low, and there are the following deficiencies: [0003] For example, the application number is 201710318126.7, and the patent name is an invention patent for a solid waste rotary furnace waste heat recovery device: [0004] It is equipped w...

There is also a lot of heat in the solid material produced by production and the smoke produced by rotary kiln calcination. Heat recovery is an important way to reduce process energy consumption and improve energy utilization efficiency. However, the solid waste rotary kiln used in the prior art The energy utilization efficiency of the waste heat recovery device is low, and there are the following deficiencies:

[0006] (1) During the calcination process, the heat absorbed by the furnace wall will be wasted;

[0007] (2) The heat generated by calcination in the furnace cannot be used reasonably by heating the water tank through the condensation pipe
