Heating plate and thermal reactor consisting of same

Abstract

The invention relates to a heating plate and a thermal reactor consisting of the same, which belong to the technical field of heating and cracking brown coal, oil shale, biomass and waste. The heating plate comprises a bottom plate and a heat conducting ball, wherein one end of the bottom plate is connected with an external heating device; and the heat conducting ball is fixed on the bottom plate. The thermal reactor provided with the heating plate comprises a sealed tank body and an external heating jacket which is provided with a heat insulation layer, wherein a feeding hole and a discharging hole are formed on the sealed tank body; and the main part of the sealed tank body is positioned in the external heating jacket. The thermal reactor is characterized by also comprising a plurality of heating plates, wherein one end of every heating plate is welded on the inner wall of the sealed tank body; and the plurality of heating plates are spirally arranged. The heating plate and the thermal reactor have the advantages of capacity of heating a large number of materials, uniformly distribution and heating, high heating efficiency, heat source saving and wide range of adaptable materials.

Description

technical field [0001] The invention belongs to the technical field of thermal cracking of lignite, oil shale, biomass and waste, and relates to a heating plate and a thermal reactor formed thereof. Background technique [0002] Most of the existing thermal reactors use screw conveyors with auger structure. Its structural features: spiral blades are welded on the rotating shaft of the screw conveyor, and the blades have solid surface type, belt type, etc. Surface type, blade surface type and other types. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to give the opposite force to the screw shaft with the material. During the conveying process of granular or powdery materials, the rotating helical blades push the materials for screw conveying. Due to the weight of the material itself and the frictional resistance of the screw conveyor casing to the material, the material cannot rotate with the blades of the screw conv...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the total amount of materials processed by the existing thermal reactor is small and the thermal efficiency is low, the present invention provides a heating plate and a thermal reactor composed of it, which can heat a large amount of materials, distribute and heat uniformly, and have high heating efficiency. Save heat source and adapt to a wide range of materials
