Description

Technical Field

[0001] This utility model relates to the field of combustion reactor technology, and specifically to a catalytic combustion reactor. Background Technology

[0002] During the casting of resin sand, a large amount of volatile organic compounds (VOCs) are generated, which pollute the air. Catalytic combustion reactors are reaction purification devices that burn off VOC emissions to remove impurities. They mainly use activated carbon adsorption towers to centrally adsorb VOC emissions, and then centrally desorb them, thereby increasing the concentration of VOCs in the air to the concentration required for combustion. The VOCs are then centrally burned and discharged through a combustion furnace. The heat generated by combustion can be transferred back to the activated carbon adsorption tower by a desorption fan, and then desorbed again at high temperature, thus achieving the recycling of energy. However, in actual use, the activated carbon inside the activated carbon adsorption tower is placed directly inside the tower. This means that when replacing it, the activated carbon needs to be shoveled out and new activated carbon poured in. The accumulation of activated carbon inside the tower prevents complete adsorption and desorption during the adsorption and desorption process. Activated carbon piled in the middle has weaker adsorption and desorption capabilities, which affects the efficiency of adsorption and desorption and is very inconvenient. In addition, the density of organic gases inside the VOCs is uneven, which can cause them to float or settle. Since the inlet pipe is usually located above the combustion plate, the less dense gases will float up and cannot pass through the bottom combustion plate, resulting in poor combustion effect and is very inconvenient. To address the aforementioned problems, this application proposes a catalytic combustion reactor. Utility Model Content
