餐厨垃圾联合筛选系统  Kitchen waste combined screening system 技术领域  Technical field
本发明公开一种餐厨垃圾处理装置,更具体涉及一种餐厨垃圾联合筛选系统。  The invention discloses a kitchen waste treatment device, and more particularly relates to a kitchen and kitchen garbage joint screening system.
背景技术Background technique
废弃物资源化利用的科学技术,经过长时间的应用,已证明了一个道理,就是如果废弃物的资源化处理技术单一应用,其后果将会对人类生存环境带来更大的危机,尤其是产生二次污染的严重问题难以控制,所以废弃物的综合处理已经成为当前发展的趋势。餐厨垃圾的组成极其复杂,其中包含污水、塑料袋、塑料瓶、废布条、腐败性有机物、纸张、金属瓶罐、破碎玻璃、破碎陶瓷片、动物油脂、植物油脂、原生细菌体等物质。目前餐厨垃圾资源化处理技术在国内外的方法和工艺中已呈现“百花齐放”局面,但是基本都是单纯的单项处理,没有走向从单纯的处理转向综合处理、利用与处置的国际性环保处理趋势和方向,可能会造成餐厨垃圾中的必然附着物进行转移及乱填乱放,造成水土污染,或转移,不仅堵塞城市下水管道,散发恶臭气味,造成严重的二次污染。餐厨垃圾的单一处理工艺从资源化利用价值考虑是可行的,但从长期保护地球环境、人民宜居、保护大气环境的综合性角度来考虑,还是可能弊大于利。而且,目前的餐厨垃圾处理装置中,有用物料、塑料、玻璃、木料等等分离不够彻底,甚至无法分离,在进一步处理时,容易因为杂质含量较多,而造成副产品质量不合格等。The science and technology of waste resource utilization, after a long period of application, has proved that if the waste recycling technology is applied in a single application, the consequences will bring greater crisis to the human living environment, especially The serious problem of secondary pollution is difficult to control, so the comprehensive treatment of waste has become the current development trend.

At present, the kitchen waste resource treatment technology has presented a “hundred flowers” situation in the domestic and foreign methods and processes, but basically it is a simple single item treatment, and there is no international environmental treatment that shifts from simple treatment to comprehensive treatment, utilization and disposal. The trend and direction may cause the inevitable attachments in the kitchen waste to be transferred and randomly filled, causing water and soil pollution, or transfer, not only blocking the city's sewer pipes, but also emitting a foul smell and causing serious secondary pollution. The single treatment process of kitchen waste is feasible from the perspective of resource utilization value. However, considering the comprehensive protection of the global environment, people's livability and protection of the atmospheric environment, it may still do more harm than good. Moreover, in the current kitchen waste treatment device, the separation of useful materials, plastics, glass, wood, etc. is not thorough enough, and even cannot be separated.
