Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of flue gas sensible heat recovery, and particularly relates to a flue gas sensible heat recovery device for a capacitor carbon activation furnace. BACKGROUND
[0002] In the field of industrial production, efficient use of energy and energy saving and emission reduction are key elements to promote the sustainable development of the industry. Flue gas sensible heat recovery, as an important energy-saving technology, plays an important role that cannot be ignored. It mainly converts the sensible heat carried by flue gas, i.e. the part of heat whose temperature is higher than that of the environment, into usable heat energy by means of a heat exchange device. This technology is widely used in the waste heat recovery link in industrial production, and is particularly common in high-temperature flue gas emission equipment such as metallurgical furnaces, boilers and kilns. For example, in the flue gas waste heat recovery scene of gas turbines and internal combustion engines, through flue gas sensible heat recovery, the exhaust gas temperature can be significantly reduced, the energy utilization rate can be greatly improved, the production cost of enterprises can be saved, and the thermal pollution to the environment can be reduced. The capacitor carbon activation furnace is the core equipment for preparing high specific surface area super activated carbon by chemical activation method. It uses chemical activation method (such as alkali activation) to produce super activated carbon. This super activated carbon has excellent performance and is widely and importantly used in supercapacitor electrode materials, gas adsorption, wastewater treatment and many other fields. However, during the operation of the capacitor carbon activation furnace, a large amount of flue gas carrying heat energy is generated. In order to realize the recycling of energy, reduce production cost, and reduce energy waste and environmental pollution, a flue gas sensible heat recovery device is usually used in combination to maximize the recovery and utilization of heat energy in the flue gas. However, the existing flue gas sensible heat recovery device still has the following disadvantages in use: 1. In the existing flue gas sensible heat recovery device, when the heat energy, dust and flue gas are separated, there is a problem of insufficient number of channels. This limits the flow range of the flue gas during heat recovery in the recovery furnace, and the contact area and contact time of the flue gas with the heat exchange device are insufficient, which leads to a relatively low heat energy conversion rate. At the same time, the device lacks effective filtering and separating means for a large amount of dust carried in the flue gas. A large amount of dust accumulates in the recovery device, not only occupies a large space, but also, after mixing with the flue gas, interferes with the normal conversion process of heat energy, further reducing the heat energy recovery effect. In addition, the mixed state of dust and flue gas also increases the difficulty of separating flue gas and dust in the later stage, and increases the equipment maintenance cost and operation complexity; 2. Existing flue gas sensible heat recovery devices also have significant deficiencies in the flue gas separation and emission process. Firstly, the limited number of flue gas circulation channels results in a small cross-section for flue gas emission, limiting flue gas emission efficiency. Secondly, existing devices rely primarily on the flue gas's natural flow to discharge flue gas, lacking an effective power-driven or auxiliary emission mechanism. This passive emission method results in slow flue gas emission, significantly reducing the recovery device's overall flue gas treatment efficiency and impacting the continuity and stability of the entire production process.
