Description

Technical Field

[0002] As an adsorption material, activated carbon is widely used in environmental protection, chemical, food, medicine and water treatment industries. Due to its unique pore structure, activated carbon has a strong adsorption capacity and can effectively adsorb various organics, inorganics, gas molecules and heavy metal ions. However, in long-term use, due to the adsorption of too many substances, the adsorption capacity of activated carbon will continue to decline. At this time, the activated carbon needs to be activated and regenerated to restore its adsorption performance. The activation and regeneration of activated carbon mainly includes the steps of desorbing adsorbed substances, opening blocked pores and reconstructing pores. Usually, the activated carbon is placed under high temperature conditions in an activation furnace. After introducing external air into the activation furnace, high temperature is applied in the combustion chamber of the activation furnace to desorb, activate and regenerate the activated carbon. At the same time, the activation furnace will produce flue gas during use, which will contain a large amount of waste heat. At present, the flue gas of the activation furnace is mostly discharged directly, resulting in the waste heat contained in the flue gas being wasted, resulting in increased production costs and waste of resources.

[0022] The utility model discloses an activated carbon energy-saving activation and regeneration device, which is used for recycling the waste heat of the flue gas discharged from the activation furnace 1, and is applied to the air intake of the activation furnace 1 to realize the activation and regeneration of the activated carbon. When the activation furnace 1 is in use, the external air is transported into the interior thereof through the first air intake pipe 2. When the high-temperature activation and regeneration is performed, the flue gas generated inside thereof will be discharged through the flue gas outlet pipe 3 and enter the heat storage chamber 11 of the recovery box 4. The heat in the flue gas will be absorbed by the heat storage ceramic 8 in the heat storage chamber 11, and then the flue gas can be discharged to the outside through the air outlet pipe 10. When the heat storage ceramic 8 in the heat storage chamber 11 is heated to a high temperature, the flue gas will be discharged to the outside through the air outlet pipe 10. After the ceramic 8 has absorbed sufficient heat, the electric turntable 6 can be turned on. The electric turntable 6 can drive the rotating plate 7 to rotate, so that the heat storage ceramics 8 in the heat storage chamber 11 and the heat release chamber 12 can be exchanged. At this time, the heat storage ceramics 8 with heat enter the heat release chamber 12, and the external air enters the heat release chamber 12 through the second air inlet pipe 9, and exchanges heat with the heat storage ceramics 8 after contacting. Then the air with heat can enter the first air inlet pipe 2 through the preheating pipe and be transported to the activation furnace 1, so that the waste heat in the flue gas is used for the activation and regeneration of activated carbon, avoiding waste of resources and reducing production costs.

[0023] When the heat storage ceramic 8 with heat enters the heat release chamber 12, the heat storage ceramic 8 without heat will enter the heat storage chamber 11, so that the heat storage process can be carried out uninterruptedly and the flue gas containing a large amount of residual heat is prevented from being directly discharged to the outside to cause energy waste.

[0024] Preferably, the waste heat recovery mechanism further includes a valve 14 , and the valve 14 is arranged on the air outlet pipe 10 and the second air inlet pipe 9 .

The three-way valve 16 can connect the first vertical pipe 18 with the second vertical pipe 19 or the horizontal pipe 15, so that the air intake of the activation furnace 1 is divided into two directions. The external air can directly enter the first vertical pipe 18 through the second vertical pipe 19 to realize the air intake of ordinary air, and the hot air in the heat release chamber 12 after heat exchange with the heat storage ceramic 8 can enter the first vertical pipe 18 through the horizontal pipe 15, providing the activation furnace 1 with air containing heat, so as to quickly heat up the activated carbon, improve the activation regeneration efficiency, and reduce the production cost.

[0028] Preferably, the waste heat recovery mechanism also includes an air bag 20, an air pump 21 and an air pipeline 22.

The waste heat recovery mechanism also includes an air vent pipe 23 and an air valve 24. The air vent pipe 23 is connected to the air pipeline 22, and the air valve 24 is arranged on the air vent pipe 23.

[0029] The electric turntable 6 is arranged at the opening 13. When it drives the rotating plate 7 to rotate, the heat storage ceramic 8 can rotate at the opening 13 to change its position. When the heat storage or heat release process is in progress, the air pump 21 can transport external air to the airbag 20. After the airbag 20 is inflated, the gap between the opening 13 and the rotating plate 7 and the electric turntable 6 can be sealed to prevent the air between the heat storage chamber 11 and the heat release chamber 12 from flowing mutually, thereby ensuring the stable progress of the heat storage or heat release process. When the position of the heat storage ceramic 8 needs to be changed, the air valve 24 is opened to discharge the air in the airbag 20 to the outside through the air supply pipe 22 and the air release pipe 23, thereby ensuring that the rotating plate 7 can rotate smoothly.
