A heat recovery device

Abstract

The present invention proposes a thermal regeneration device, which includes a hoist for transporting materials, one side of the hoist is provided with a feeding tower, one end of the hoist communicates with one end of the feeding tower, the The other end of the hoist is provided with an induced draft fan communicated with the hoist, the other end of the feed tower is provided with a drum, and the drum is provided with a burner for heating the material, and the drum is also provided with a output box. In the heat regeneration equipment with this structure, during the working process, under the action of the induced draft fan, the movement direction of the high-temperature flue gas is opposite to the flow direction of the material. While preheating the feeding tower, it can also remove the dust in the flue gas. Adsorption and recovery, therefore, the energy consumption and pollution are small, and the thermal efficiency is high.

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
