[0019] The following is a detailed description of the embodiments of the technical solution of the present application in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] like Figure 1 An insulating and pressurized activation furnace provided in an embodiment of the present application is illustrated, the activation furnace comprising a furnace wall and a steel plate layer 104. In the insulating and pressurized activation furnace provided in this embodiment, the furnace wall is arranged from the inside of the furnace body to the outside with refractory bricks 101, insulating bricks 102, and red bricks 103; the steel plate layer 104 is arranged on the outer layer of the furnace wall, the steel plate layer 104 is welded by multiple steel plates, and seals and surrounds the entire periphery of the activation furnace.

[0021] The heat-insulating and pressurized activation furnace provided in this embodiment is intended to solve the problems of poor sealing, weak pressure-keeping and heat-insulating capacity, high energy consumption and low production efficiency of the activation furnace in the prior art. The refractory bricks 101 of the heat-insulating and pressurized activation furnace serve as the innermost layer of the furnace wall. They can withstand high temperatures and ensure that the furnace body remains stable in a high-temperature environment. The insulation bricks 102 are located on the outer layer of the refractory bricks, and their main function is to reduce heat loss, thereby improving the heat-insulating performance of the furnace body. The red bricks 103 serve as the outermost layer of the furnace wall. They can not only provide a certain structural strength, but also further reduce the escape of heat. A steel plate layer 104 is also provided on the outer layer of the furnace wall. This steel plate layer is welded from multiple steel plates to form a complete and sturdy outer shell. The provision of the steel plate layer 104 not only enhances the overall structural strength of the furnace body, but also further improves the sealing of the furnace body, thereby enhancing its pressure-keeping capacity and heat-insulating performance.

[0022] Through such a design, the heat-insulating and pressurized activation furnace provided in the embodiment of the present application has been significantly improved in terms of sealing, pressure-keeping and heat-insulating capabilities, energy consumption, and production efficiency.

[0023] Specifically: the improvement of sealing means that the heat and pressure in the furnace body can be better maintained, reducing energy waste. The enhancement of pressure-keeping and heat-insulating capabilities enables the furnace body to maintain high temperature and high pressure for a longer period of time, thereby improving production efficiency. The heat-insulating and pressurized activation furnace of the present application effectively solves the problems existing in the prior art by optimizing the furnace wall structure and adding a steel plate layer. The pressure-keeping capacity of the heat-insulating and pressurized activation furnace provided in this embodiment is increased from 60Pa to 120Pa in the prior art to 200Pa to 300Pa, reducing energy consumption by about 20%, and increasing production efficiency by about 20%.

[0024] In the heat-insulating and pressurized activation furnace provided in this embodiment, the furnace body formed by the furnace wall includes: a heat storage chamber 12; a feed port 13, a supplementary carbonization section 14, an activation section 15 and a discharge device 16 arranged in sequence from top to bottom; the heat storage chamber 12 is connected to the supplementary carbonization section 14 and the activation section 15 through a channel.

[0025] In this embodiment, the main function of the heat storage chamber 12 is to provide heat, which can provide a stable heat source to the inside of the furnace body. The feed port 13 is the entrance for the carbonized material to enter the furnace body, the supplementary carbonization section 14 is the area where the raw materials are carbonized, and the activation section 15 is the core part of the furnace body, where the raw materials are deeply activated. By accurately controlling the temperature, pressure, atmosphere and other conditions of the activation section, high-quality activated products can be obtained. The discharge device 16 is responsible for discharging the activated product from the furnace body to complete the entire activation process.

[0026] An improvement, the vent pipes 2 are arranged at intervals on the furnace wall, the vent pipes 2 are connected to the inside and outside of the furnace body, and the vent pipes 2 are distributed in the areas where the heat storage chamber 12, the supplementary carbonization section 14, and the activation section 15 are located. The vent pipes 2 located on the heat storage chamber 12 are conducive to the effective transfer of heat. By controlling the air flow rate entering the heat storage chamber through the vent pipes 2, the temperature and atmosphere in the heat storage chamber can be controlled. In the furnace body, water vapor and air can be introduced into the furnace body through the vent pipes 2 to provide the necessary oxygen for the activation reaction, and at the same time, the waste gas generated during the activation process is discharged to maintain the stability of the furnace environment. Through the layout of the vent pipes 2 and the ventilation volume, the activation reaction can be regulated and the activation efficiency and product quality can be improved.

[0027] In one improvement, a fire-watching hole 3 and a temperature-measuring port pipe 4 are arranged at intervals on the furnace wall. The fire-watching hole 3 is arranged mainly to facilitate the operator to observe the combustion condition in the furnace. The temperature-measuring port pipe 4 is used to install a temperature-measuring device to monitor the temperature in the furnace in real time. By arranging the fire-watching hole 3 and the temperature-measuring port pipe 4, the operator can more conveniently monitor and control the temperature condition in the furnace, which provides a strong guarantee for the activation process.

[0028] In order to further improve the pressure-keeping and heat-insulating performance of the activation furnace, a steel plate layer 104 is arranged outside the furnace wall of the feed port 13, the supplementary carbonization section 14, the activation section 15 and the discharge device 16, and the entire outer periphery of the furnace body is sealed to form the entire activation furnace into a closed furnace, thereby improving the pressure-keeping and heat-insulating performance of the activation furnace.

[0029] Preferably, the insulation brick 102 is a diatomite insulation brick. Diatomite is a natural inorganic material, and its internal porous structure gives diatomite good insulation performance, which can effectively reduce heat loss. At the same time, diatomite insulation bricks also have good thermal stability and chemical stability, and can maintain their performance unchanged for a long time under high temperature environment. In the insulation and pressurization activation furnace, diatomite insulation bricks are used for the outer layer of the furnace wall, and together with refractory bricks and red bricks, they constitute the insulation structure of the furnace body. Through the use of diatomite insulation bricks, the furnace body can maintain a higher temperature during operation, reduce heat loss, and thus improve the thermal efficiency of the activation furnace. In addition, diatomite insulation bricks also have certain environmental protection properties. It does not contain harmful substances, does not pollute the environment, and is easy to recycle. Therefore, in the pursuit of green and environmentally friendly industrial production, diatomite insulation bricks are an ideal insulation material.
