Heat regeneration device

Abstract

The invention provides a heat regeneration device, comprising an elevator for conveying materials. One side of the elevator is provided with a feeding tower; one end of the elevator is communicated to one end of the feeding tower; the other end of the elevator is provided with an induced draft fan communicated with the elevator; the other end of the feeding tower is provided with a roller; the roller is provided with a combustor for heating the materials and a material-discharging tank. With the structure, a moving direction of high temperature smoke is opposite to a flowing direction of the material under the effect of the induced draft fan during a working process, so that the heat regeneration device can absorb and recover smoke dust in the smoke while preheating the feeding tower, thereby having relatively small energy consumption and pollution and high thermal efficiency.

Description

technical field [0001] The invention relates to the field of thermal regeneration machinery, in particular to thermal regeneration equipment. Background technique [0002] As the supply of social resources becomes more and more tense, mechanical products such as thermal recycling equipment that can be used to regenerate waste mixtures such as asphalt have gradually become the focus of attention. [0003] Hot recycled asphalt mixture is the waste material milled and planed on the asphalt pavement, which is heated and mixed with new asphalt mixture in a certain proportion, and the recycled material is added and stirred evenly. The mixture can be recycled. It should be noted that this mixture is different from conventional stone materials. There is asphalt on the surface of the milled waste materials, which will melt when heated. Usually, its fluidity is poor. When the temperature is 110-120 degrees, its viscosity is high. Easy to agglomerate and stick. After the temperature ...

AI Technical Summary

Problems solved by technology

[0007] First of all, the airflow temperature at the discharge end must be greater than the discharge temperature of the recycled material to produce recycled materials that meet the requirements. This method will generate a large amount of high-temperature exhaust gas, resulting in energy waste;

[0008] Secondly, the drum has problems such as low heating efficiency and large heat loss. At the same time, the high-temperature exhaust gas contains a large amount of asphalt dust, which has a great impact on the environment;

[0009] Thirdly, the regenerated material in the drum is heated by flame radiation, and there is a risk of excessive local temperature and material aging
