一种新型垃圾焚烧发电废水浓液的处理工艺技术

垃圾发电涉及烟气、废水、炉渣及飞灰的三废处理,如何在全厂工艺中合理消纳废水、这涉及各类设备新材料的应用以及结合生产中各种工艺的相互穿插应用,以便在工艺中的各环节,消纳废水。我国垃圾发电行业起步晚,各工艺独立且单一,本文以项目实例,在烟气处理工艺中,采用新型旋转雾化器,引入废水的浓液作为旋转雾化器冷却水,达到烟气处理与废水浓液处理两种工艺交叉,一起重叠处理,在烟气中蒸发,与常规垃圾电厂将浓液泵入石灰浆溶液中再达到旋转雾化器相比,开辟了一条有效的路径。

A new type of treatment technology for concentrated waste liquid from waste incineration power generation

Waste-to-energy power generation involves the three waste treatments of flue gas,waste water,slag and fly ash. How to reasonably absorb waste water in the whole plant process. This involves the application of various types of equipment and new materials and the interpenetration of various processes in the combined production. Application in order to absorb waste water in all aspects of the process. China’s waste-to-energy industry started late,and each process is independent and single. In this paper,the project example is used in the flue gas treatment process. A new type of rotary atomizer is used and the concentrated liquid of wastewater is introduced as the cooling water of the rotary atomizer. The two processes of wastewater concentrated liquid treatment intersect,overlapped together,and evaporate in the flue gas. Compared with the conventional waste power plant pumping the concentrated liquid into the lime slurry solution and then reaching the rotary atomizer,it opens up an effective path.
