一种工业污水处理用多级沉淀装置
本技术属于环保设备
,特别涉及一种工业污水处理用多级沉淀装置。
技术介绍
长期以来,工业污水一直是制约工业快速发展的问题之一,且如何处理工业污水也是大家关注的问题;因此,如何对工业污水进行科学合理的治理,一直以来是国内外专家努力的课题;沉淀是污水治理常用的工艺之一,其利用水的自然沉淀或混凝沉淀的作用来除去水中的悬浮物,传统的沉淀装置占地面积较大,且在执行沉淀操作时只能利用时间的推移慢慢自然沉淀,其完成沉淀所需的时间长,效率低下。
技术实现思路
本技术的目的是克服现有技术中不足,提供一种工业污水处理用多级沉淀装置,进水管与内筒切向连接,在内筒内部先进行旋流除砂,去除大部分沉淀物,再在外筒中进行沉淀,增强了污水沉淀的效果,提高了污水沉淀的效率。为了实现上述目的,本技术采用的技术方案是:一种工业污水处理用多级沉淀装置,包括外筒、内筒、进水管、集砂斗、支腿、卸料阀Ⅰ、短接、环管、出水管,所述内筒上部一侧设有进水管,所述进水管与内筒切向连接,污水通过进水管切向进入内筒内部,污水中的部分尘粒在重力和离心力的作用下被内筒内壁捕集;所述内筒外部一侧设有外筒,污水中的尘粒在外筒中再次在重力的作用下沉降,增强了污水沉淀的效果;所述外筒上部一侧设有若干均匀分布的短接,短接与外筒贯通连接,沉淀后的污水通过短接排出,设置多个短接提高了污水排放的效率;短接通过环管连接,所述短接一侧设有出水管,所述外筒下部一侧设有集砂斗,所述集砂斗为漏斗形,所述集砂斗外部一侧设有若干支腿,所述集砂斗下部一侧设有卸料阀Ⅰ。优选的,所述卸料阀Ⅰ下部一侧设有卸料阀Ⅱ,所述卸 ...
