本发明涉及高温烟气处理技术领域，具体说是一种高温烟气除尘吸热装置。The invention relates to the technical field of high-temperature flue gas treatment, in particular to a high-temperature flue gas dust removal and heat absorption device.
背景技术Background technique
目前工业领域，炉窑被广泛采用以化石燃料燃烧产生热能达到某种生产目的，工业炉窑燃料燃烧后排放出烟气，烟气是固体、液体和气体物质组成的多相气溶胶，主要成份是CO2、H2O、CO、NO和烟尘，其中烟尘属粒子污染物，而粒子污染物是大气的重要污染物之一，而大气污染已经日益严重地直接危害到人体的舒适、健康，乃至人类赖以生存的环境，烟气中的有害成份需要通过改善燃烧和除尘来降低排放。At present, in the industrial field, furnaces are widely used to burn fossil fuels to generate heat to achieve certain production purposes. Industrial furnaces emit flue gas after fuel combustion. Flue gas is a multi-phase aerosol composed of solid, liquid and gaseous substances. The main components They are CO2, H2O, CO, NO and soot. Among them, soot belongs to particle pollutants, and particle pollutants are one of the important pollutants of the atmosphere. Air pollution has become increasingly serious and directly endangers the comfort and health of the human body, and even human dependence. In the living environment, the harmful components in the flue gas need to be reduced by improving combustion and dust removal.
传统的工业炉窑烟气除尘，主要采用机械除尘、静电除尘、过滤式布袋除尘、洗涤式湿法除尘等。由于高温烟气对传统除尘器的设备、过滤材质具有很强侵蚀破坏力，还会对除尘器结构产生热膨胀的影响，而传统除尘器的适用温度低，因此，高温除尘效果不好，一般只能在50-200℃之间有效工作。Traditional industrial furnace flue gas dust removal mainly adopts mechanical dust removal, electrostatic dust removal, filter bag dust removal, washing wet dust removal, etc. Because high-temperature flue gas has strong erosive and destructive power on the equipment and filter materials of traditional dust collectors, and will also have an impact on thermal expansion of the structure of the dust collector, while the applicable temperature of traditional dust collectors is low, so the high-temperature dust removal effect is not good, generally only Can work effectively between 50-200°C.
对于温度达200℃-1000℃及以上的高温烟气的除尘，目前主要采用先降温再用传统除尘器除尘的办法；降温方法主要有直接冷却如：采用野风冷却、水冷却等。野风冷却降温后烟气量增大，余热回收效率低，热量损失大；水冷却降温则增加除尘系统的复杂程度，降温效果也不好。For the dust removal of high-temperature flue gas with a temperature of 200°C-1000°C and above, at present, the method of first cooling down and then using a traditional dust collector to remove dust is mainly used; the cooling method mainly includes direct cooling, such as wild wind cooling, water cooling, etc. After wild wind cooling, the flue gas volume increases, waste heat recovery efficiency is low, and heat loss is large; water cooling increases the complexity of the dust removal system, and the cooling effect is not good.
美、德、日本等国将电除尘器用于高温除尘进行了探索，目前主要处在实验阶段，已有达到在650～790℃、570kpa下运行100小时的实验记录，除尘效率可达到95％～99.5％；但存在电晕放电不稳定、电极寿命短、对烟气成分敏感、高温绝缘等问题，短时间内，很难突破。The United States, Germany, Japan and other countries have explored the use of electrostatic precipitators for high-temperature dust removal. At present, they are mainly in the experimental stage. There have been experimental records of operating at 650-790 °C and 570kpa for 100 hours, and the dust removal efficiency can reach 95%~ 99.5%; but there are problems such as corona discharge instability, short electrode life, sensitivity to smoke components, high temperature insulation, etc., and it is difficult to break through in a short time.
已研究或正在研究的高温除尘技术还有陶瓷织状过滤器、陶瓷纤维过滤器、金属毡过滤器、烧结金属丝网管过滤器、太棉过滤器等等，这些除尘器的过滤效率都能达到99％以上，但都存在各自的问题，如强度问题、永久性堵塞失效问题、成本问题等。The high-temperature dust removal technologies that have been studied or are being studied include ceramic woven filters, ceramic fiber filters, metal felt filters, sintered wire mesh tube filters, too-cotton filters, etc. The filtration efficiency of these dust collectors can reach More than 99%, but they all have their own problems, such as strength problems, permanent blockage failure problems, cost problems, etc.
国内有各种颗粒层过滤器的报道，主要是移动床颗粒层过滤器和沸腾床颗粒层过滤器，这些颗粒层过滤器都采用烟气从上向下经过颗粒床，颗粒在反吹清灰时呈流态化或沸腾状。这种颗粒层过滤器仍然没有改变传统颗粒层过滤器烟气从上向下经过颗粒床，仍然存在灰尘在颗粒床上部难于清理的问题，流态化的反吹清灰容易产生不稳定运行，影响除尘效率。并且现有的除尘器没有针对高温烟气的余热回收与有效利用。There are various reports of particle layer filters in China, mainly moving bed particle layer filters and fluidized bed particle layer filters. When it is fluidized or boiling. This particle layer filter still does not change the traditional particle layer filter. The flue gas passes through the particle bed from top to bottom, and there is still the problem that the dust is difficult to clean on the upper part of the particle bed. Fluidized back-blowing dust cleaning is prone to unstable operation. Affect the dust removal efficiency. Moreover, the existing dust collectors do not have waste heat recovery and effective utilization for high-temperature flue gas.
