Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Examples
In a specific embodiment, as shown in fig. 1, a rotary reaction furnace for pyrolysis includes a furnace body 1, a cavity 2 and a closed bottom plate 3; the cavity 2 and the closed bottom plate 3 are positioned inside the furnace body 1, the closed bottom plate 3 is positioned below the furnace body 1 and closes the cavity 2, the closed bottom plate 3 is provided with a plurality of heat-resistant elastic plates 4, and the heat-resistant elastic plates 4 are connected with the closed bottom plate 3 through elastic hinges.
In this embodiment, in order to solve the problem of the difficult processing cinder of pyrolysis in-process, a new rotary furnace has been designed, at first, cavity 2 has been set up in the bottom of furnace body 1 and has been used for storing the cinder after the pyrolysis, prevent through closed bottom plate 3 that the pyrolysis material leads to the pyrolysis efficiency variation with the cinder of cavity 2 inside mixture, heat-resisting elastic plate 4 that sets up at closed bottom plate 3 is then in order to improve the automation level of whole system, when the pyrolysis goes on to a certain extent, along with the continuous joining of material, the pressure that closed bottom plate 3 received enlarges gradually, and when reaching the threshold value, heat-resisting elastic plate 4 opens, old material gets into cavity 2, thereby the pressure that receives diminishes on heat-resisting elastic plate 4, because the effect of elastic hinge, heat-resisting elastic plate 4 resumes to the initial position, also constitute plane closed cavity 2 with closed bottom plate 3 promptly. This embodiment is simple in construction and easy to use and does not cause the problem of newly added material entering the cavity 2. The technical problem that the pyrolysis efficiency of the traditional rotary furnace is poor after new and old materials are mixed along with the continuous addition of the materials is also solved.
In a preferred embodiment, the resilient hinge material is a cermet.
In the present embodiment, in order to prevent the twisting power performance of the elastic hinge from being deteriorated by heat, a cermet material is used which has both the toughness of metal and the heat resistance of ceramic.
In a preferred embodiment, the closed bottom plate 3 and the heat-resistant elastic plate 4 are both heat-insulating materials.
In order to prevent the heat from entering the cavity to cause the degradation of the pyrolysis efficiency in the furnace body 1, the heat insulation material is adopted to ensure that most of heat is kept at the position above the closed bottom plate 3, and the material is fully pyrolyzed.
In a preferred embodiment, the bottom of the furnace body 1 is also provided with a pressure sensor 5.
In the embodiment, the pressure sensor 5 is used for preventing the excess coal cinder in the cavity 2 from causing the function failure of the heat-resistant elastic plate 4 and the automatic coal cinder storage function of the cavity 2, and when the pressure at the bottom of the cavity 2 reaches a preset value, the operation is closed and the coal cinder is cleaned.
In a preferred embodiment, a refractory layer 6 is provided within the furnace body 1.
When the material gets into furnace body 1, direct contact flame retardant coating 6, indirect heating prevents that the material from influencing the pyrolysis efficiency of material because of the high temperature at the beginning.
In a preferred embodiment, a thermal insulating jacket 7 is provided between the refractory layer 6 and the furnace body 1.
The heat-insulating jacket 7 is used for reducing the heat loss in the furnace body 1 and improving the pyrolysis efficiency.
