Description

生活垃圾中塑料及化学有害物的处理装置 技术领域
本发明涉及环保机械技术领域，具体是一种生活垃圾中塑料及化学有害物的处理装置。
背景技术
生活垃圾的公害是塑料及化纤有毒制品，目前针对生活垃圾的有害化处理方式基本是采用人工分类处理，经过多年实践，成本太高，难以实施。因此，常见的生活垃圾处理装置是将其填埋或者堆积后燃烧，由于大量使用土地，形成严重污染，危害着人们的生命健康；垃圾堆积后燃烧，比如采用柴油焚烧形式，由于投资过大，燃烧成本过高，废弃物二次污染等问题，也难以广泛推广；而利用焚烧垃圾的热能发电或供热，虽然垃圾处理的比较彻底，但存在建设投资规模大，投资回收期过长，不能实现生活垃圾再利用，燃烧过程产生二次污染的问题，近些年来，国家对环境保护，以及对城市生活垃圾的处理给予了高度重视，并投入大量的财力、物力、人力进行治理和控制，由于处理设备及技术相对滞后，还远未达到较为理想有效的处理目的，这与生活垃圾处理走“无害化、减量化、资源化、产业化”的道路要求相差甚远。
发明内容
本发明旨在解决上述问题，从而提供一种能够实现生活垃圾的无害化、减量化、资源化、产业化处理的生活垃圾中塑料及化学有害物的处理装置。
本发明解决所述问题，采用的技术方案是：
一种生活垃圾中塑料及化学有害物的处理装置，包括入料端输送带、集尘罩、罐体、高压喷火器、高压吹风机、引风机和出料端输送带，集尘罩设置在罐体上部，罐体一侧设置有连通罐体内部的入料通道，入料通道的进料口连接入料端输送带，入料通道的出料口位置处设置有用于击打垃圾并扬成散状抛入罐体内部的带齿扬料铲，高压喷火器的喷管和高压吹风机的吹风管分别伸入至罐体内部，高压喷火器的喷管设置在高压吹风机的吹风管上方，集尘罩的底部设置有塑料残渣及有害气体出口，引风机设置在塑料残渣及有害气体出口位置，罐体底部设置有垃圾出口，垃圾出口下方设置有连接出料端输送带的接料斗。
采用上述技术方案的本发明，与现有技术相比，其突出的特点是：
解决了现有生活垃圾中塑料分离采用人工分类处理，垃圾处理工艺成本过高、工艺复杂、消耗大、难普及、存在二次污染等问题，通过本装置的带齿扬料铲将生活垃圾物料击打并扬 成散状抛入罐体内部，由于塑料、化纤有害物与其他垃圾比重不同，在重力作用下，被罐体底部的高压风机由底部向上吹起，使垃圾中的塑料、化纤有害物与其他垃圾快速分离，再通过高压喷火器将罐体内的塑料、化纤有害物通过悬浮燃烧法瞬间燃烧掉，未燃尽的塑料残渣及有害气体被集尘罩底部引风机吸走回收，有用垃圾由罐体底部垃圾出口排出；通过空中喷火处理，能够做到无污染、零排放，并且，垃圾处理可以全程自动化，成本超低，一次性快速完成，本装置尺寸可大可小，普及率高，大小城市及乡镇均可适用，解决了处理垃圾中长途运输及成本过高等问题，具有很强的推广操作性、实用性。
作为优选，本发明更进一步的技术方案是：
集尘罩上部为锥体结构，集尘罩底部设置有倾斜布置的导料底板。
罐体底部呈倒锥体结构。
