Description

Technical Field

[0001] This utility model relates to the field of activated carbon and activated coke preparation technology, and in particular to a two-half furnace interconnected activation furnace. Background Technology

[0002] Activated carbon is a specially treated type of carbon. Organic raw materials such as fruit shells, coal boxes, and wood are heated in the absence of air to reduce non-carbon components. This process is called carbonization. Then, it reacts with gas, and the surface is eroded, producing a structure with well-developed micropores. This process is called activation. Because the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, which results in the surface of activated carbon having countless tiny pores. As we all know, the activation furnace plays an indispensable role in the production process of activated carbon.

[0003] A prior art search revealed an activation furnace for activated carbon (application number CN201910248580.9), comprising a first half-furnace and a second half-furnace with the same structure. The first half-furnace includes a furnace body and a furnace core disposed inside the furnace body. The furnace body is a closed cavity with a feeding port at the top and a discharge port at the bottom. A reprocessing chamber is disposed below the discharge port and connected to the bottom of the furnace body. Several ventilation pipes for introducing oxygen-containing mixed gas are disposed on the side wall of the reprocessing chamber. The furnace body, from top to bottom, consists of a feeding section, a preheating section, a reaction section, a cooling section, a rapid cooling section, and a discharge section. This invention also includes a rapid cooling section to form a cooling gradient and avoid sudden cooling. The reprocessing chamber and ventilation pipes for introducing oxygen-containing mixed gas are disposed below the discharge port to further oxidize the activated material, thereby increasing the strength and porosity of the material. However, the temperature of the outer wall of the furnace is too high when the device is in use, which can easily cause burns to the staff. At the same time, the heat generated in the furnace body is reused, so improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a two-half-furnace interconnected activation furnace, which can reuse the heat generated by the furnace body and improve the safety of the furnace body during operation.

[0005] To achieve the above objectives, a two-half-furnace interconnected activation furnace is provided, comprising a furnace body, wherein there are two furnace bodies and a connecting pipe is fixedly connected between them, and a smoke pipe is fixedly connected to the connecting pipe. The furnace body is provided with a preheating section, a reaction section, a cooling section, a discharge section and a re-reaction section.

[0006] The furnace body is divided into an inner layer, an insulation layer, and a shell from the inside out. The inner layer, located outside the reaction section, is equipped with pipes. An insulation cotton ring is provided at the furnace opening. A material distribution plate is fixedly connected to the furnace body inside the insulation cotton ring. The material distribution plate has discharge holes around its perimeter. A sealing cover is provided at the top of the furnace body, and a ceramic insulating base, an external heat temperature monitoring hole, and a wiring terminal are fixedly connected to its outer side.

[0007] According to the two-half-furnace interconnected activation furnace, the rear side of the furnace body is provided with a water inlet and a water outlet, both of which are connected to a pipeline located on the periphery of the preheating section and the reaction section.

[0008] According to the two-half-furnace interconnected activation furnace, the reaction section is composed of a metal mesh and resistance wire.

[0009] According to the two-half-furnace interconnected activation furnace, the inner layer is a refractory layer and is made of lightweight refractory bricks.

[0010] According to the aforementioned two-half-furnace interconnected activation furnace, the insulation layer is a heat-insulating material and is made of ceramic fiber cotton.

[0011] According to the aforementioned two-half-furnace interconnected activation furnace, the shell is made of sheet metal.

[0012] According to the two-half-furnace interconnected activation furnace, the cooling section is located above the discharge section, and the re-reaction section is located at the bottom of the furnace body.

[0013] According to the two-half-furnace interconnected activation furnace, the bottom of the furnace body is fixedly connected with support legs.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with existing technologies, by incorporating insulation cotton rings, pipes, metal mesh, resistance wires, and insulation layers inside the furnace, heating is achieved in the reaction section under the action of the metal mesh and resistance wires, which also heats the water in the pipes. This further preheats the preheating section 4, improving energy utilization. During the reaction process, the insulation layer ensures a more complete reaction.

There are two furnace bodies 1, which are fixedly connected by a connecting pipe 2. The two furnace bodies 1 are controlled independently and can be operated simultaneously with controllable temperature. The connecting pipe 2 connects the preheating section 4 between the two furnace bodies 1. Under the action of the connecting pipe 2, the temperature of the preheating section 4 of the two furnace bodies 1 can be increased, which facilitates further heating of the reactants in the metal mesh 51 and resistance wire 52. The shell material and process are sheet metal processing. The bottom of the furnace body 1 is fixedly connected to three support legs 17, which are evenly distributed. A smoke pipe 21 is fixedly connected to the connecting pipe 2.

The cooling section 6 is located above the discharge section 7, and the re-reaction section 8 is located at the bottom of the furnace body 1. The cooling section 6, the discharge section 7, and the re-reaction section 8 are the same as those in the prior art, so they will not be described again in this patent.

[0026] The reaction section 5 is composed of a metal mesh 51 and a resistance wire 52. The furnace body 1 is divided into an inner layer 9, an insulation layer 13 and a shell from the inside out.
