Hybrid heating apparatus applicable to the moving granular bed filter

摘要

A structure of hybrid heating equipment according to the present invention is disclosed. The present invention combines a multiple of the thermal sources for heating the interior materials of the container simultaneously, and assures the materials could gain the thermal energy uniformity. Furthermore, the present invention allows users to control the level of the heating simply through adjusting the length of interior heating elements or the flow rate of the incoming gas. In addition, the present invention connect with the tubes of the hot exhaust gas to further lower the influence of the thermal resistance by coordinating the flow of the hot exhaust gas, therefore fully reflect the advantages of the conserving energy and reducing the carbon emissions by reusing the waste heat as the principal source while the electric heating devices as supplement.

主权项

1. A hybrid heating apparatus, comprising:
a tank, having a storage space inside, and having a top opening part and a bottom opening part on the top and bottom ends; a lid, disposed on said top opening part, and having a plurality of holes on the surface; at least an inner heating unit, inserting to said plurality of holes and downwards into said storage space; and a gas distributor, disposed at said bottom opening part, and having a plurality of gas outlets for leading a heating gas upwards and into said storage space; wherein said gas distributor has said plurality of gas outlets on a top surface and at least a gas inlet zone on a bottom surface, and an end of said gas distributor connects with an exhaust gas pipe; wherein said gas distributor extends and attaches to an inner sidewall of said tank so that said heating gas is led into said storage space from the side of said tank via said plurality of gas outlets.
