Description

Technical Field

[0001] The present application relates to the technical field of carbonization furnace equipment, and more specifically, to an energy-saving carbonization furnace. Background Art

[0002] When the carbonization furnace is working, it is necessary to keep a high temperature inside the furnace body. The existing insulation furnace lining is generally composed of multiple layers of carbon felt. The insulation effect of this insulation furnace lining composed of multiple layers of carbon felt is limited and the insulation performance is poor. Therefore, there is serious heat loss in the heating zone of the carbonization furnace. The temperature in the furnace will diffuse into the air, resulting in large heat energy loss and low energy utilization rate. It not only wastes energy but also increases production costs. The furnace structure and materials of the carbonization furnace also have a great influence on the loss of energy. Due to the lack of effective insulation measures, heat is easily lost during the carbonization process, resulting in energy waste. Utility Model Content

[0003] The utility model provides an energy-saving carbonization furnace, which solves the problem that the existing carbonization furnace lacks effective heat preservation measures, has poor heat preservation performance, and is easy to lose heat during the carbonization process, resulting in energy waste, through the combined use of a heat preservation layer, a reflective layer and a heat insulation layer.

[0004] The utility model is realized through the following technical solutions.

[0005] An energy-saving carbonization furnace comprises: a furnace body, the inner wall of the furnace body is provided with a high-temperature resistant protective layer, the high-temperature resistant protective layer uses refractory bricks, the outer side of the furnace body is provided with a thermal insulation energy-saving layer, the thermal insulation energy-saving layer is provided with a thermal insulation layer and a reflective insulation layer from the inside to the outside, the thermal insulation layer uses asbestos felt, the reflective layer is composed of a polished high-temperature alloy plate, the high-temperature alloy plate is closely attached to the thermal insulation layer, and the thermal insulation layer uses carbon fiber cloth.

[0006] The high temperature resistant protective layer on the inner wall of the furnace body prevents the furnace body from deformation due to high temperature. The thermal insulation layer plays a role of thermal insulation and reduces the temperature dissipation in the furnace. The reflective layer reduces heat loss and dissipation. The heat insulation layer reduces the temperature outside the furnace, thereby reducing heat dissipation.

[0007] In a further technical solution, in order to reduce the temperature loss in the carbonization furnace, an intermediate layer is provided between the reflective layer and the heat insulating layer, and ceramic coating is used in the intermediate layer.

[0008] The intermediate layer between the reflective layer and the heat-insulating layer reduces the temperature loss in the carbonization furnace, and the ceramic coating can prevent corrosion and reduce temperature dissipation.

[0009] Furthermore, in order to facilitate the arrangement of the heat insulating layer outside the middle layer, high temperature resistant glue is coated between the middle layer and the heat insulating layer.

[0010] Furthermore, in order to prevent cracks and deformation of the furnace body, a heat dissipation layer not covered with a heat-insulating energy-saving layer is provided on the furnace body.

[0011] The heat dissipation layer is not provided with a thermal insulation and energy-saving layer in order to quickly transfer heat in the furnace to achieve the best heat conduction effect, reduce costs, and prevent the furnace body from having a gap in which heat is dissipated, causing cracks and deformation in the furnace body.

[0012] Furthermore, a flange is provided between the thermal insulation and energy-saving layer and the heat dissipation layer.

[0013] The technical effects of the utility model are:

[0014] The present application uses a thermal insulation layer, a reflective layer and a heat-insulating layer in combination. The reflective layer is a polished high-temperature alloy plate, which can effectively reflect the heat dissipated from the surface of the thermal insulation layer. The heat-insulating layer uses carbon fiber cloth to reduce the temperature of the outside of the thermal insulation and energy-saving layer, thereby reducing heat dissipation, significantly reducing heat energy loss, improving energy utilization, and reducing production costs. A heat dissipation layer that is not covered with the thermal insulation and energy-saving layer is provided on the furnace body to prevent the furnace body from having a gap in which heat is dissipated, resulting in cracks and deformation of the furnace body.

Obviously, the drawings in the following description are only embodiments of the utility model.

[0021] During the implementation process, the high temperature resistant protective layer 2 on the inner wall of the furnace body 1 is to prevent the furnace body from being deformed due to too high temperature. The high temperature resistant protective layer 2 uses refractory bricks so that it will not affect the carbonization process in the furnace body 1. The thickness of the refractory bricks is between 30mm and 40mm. The refractory bricks are resistant to high temperatures and can also play a role in heat preservation, improve the efficiency of thermal energy utilization, and reduce energy consumption. The insulation layer 3 plays a role in heat preservation and reduces the temperature loss in the furnace. The thickness of the asbestos felt of the insulation layer 3 is between 25mm and 35mm. The use of asbestos felt is to utilize the asbestos felt insulation and In order to reduce the effect of heat loss, a polished high-temperature alloy plate is used as the reflective layer 4. The thickness of the polished high-temperature alloy plate is about 2mm to 5mm, which can reduce the heat dissipated by the thermal insulation layer 3. The polished high-temperature alloy plate has a good reflective effect and can effectively reflect the heat dissipated from the surface of the thermal insulation layer 3. The thermal insulation layer 5 plays a role in reducing the temperature outside the furnace. The thickness of the carbon fiber cloth of the thermal insulation layer 5 is between 1mm and 2mm. The thermal insulation layer 5 is arranged on the outermost side of the thermal insulation and energy-saving layer 6, which can protect the middle layer 7 and reduce heat loss.

[0024] During the implementation process, the middle layer 7 arranged between the reflective layer 4 and the heat-insulating layer 5 plays a secondary protection role to reduce the temperature loss in the carbonization furnace. The thickness of the ceramic coating of the middle layer 7 is between 10mm and 15mm. The middle layer 7 uses ceramic coating because the ceramic coating has a stable structure and good thermal insulation effect. High-temperature resistant glue is coated between the middle layer 7 and the heat-insulating layer 5 to facilitate the heat-insulating layer to be arranged on the outside of the middle layer 7.

[0027] During the implementation process, a heat dissipation layer 8 not covered by the thermal insulation and energy-saving layer 6 is provided on the furnace body 1. In order to prevent the furnace body from cracking, deforming and quickly transferring heat in the furnace to achieve the best heat conduction effect, reduce costs, and prevent the furnace body from having no gaps for heat dissipation, resulting in cracks and deformation of the furnace body, a flange 9 is provided between the thermal insulation and energy-saving layer 6 and the heat dissipation layer 8 to separate the thermal insulation and energy-saving layer 6 and the heat dissipation layer 8, and also to facilitate the arrangement of the thermal insulation and energy-saving layer 6.
