The invention provides an efficient silencing device, which belongs to the field of environmental protection equipment. The high-efficiency silencing device includes a circular tubular shell, the left and right ends of the shell are contracted, the left and right ends of the shell are fixed with a circular plate and two circular plates respectively, and a seal is formed between one side wall of the circular plate and the inner wall of the shell. The circular plate and two circular plates are respectively provided with an air inlet and an air outlet along the axis of the shell, and a circular tubular connecting pipe is also arranged in the shell, and the left and right ends of the connecting pipe are separately divided. The left and right ends of the connecting pipe are respectively connected with the circular plate and the circular plate. The inlet is connected with the inner cavity of the connecting pipe. The outlet and the connecting pipe are staggered. The side wall of the connecting pipe is perforated with an outlet groove which connects the inner cavity of the connecting pipe with the inner cavity of the shell. The outlet groove has many straight strips. The length of the outlet groove extends along the axis of the shell and is filled in the connecting pipe. Filled with sound absorbing cotton, the ratio of outer diameter of connecting pipe to inner diameter of middle shell is less than one third. The invention has the advantages of good muffling effect.

一种高效消音装置
本专利技术属于环保设备领域,涉及一种高效消音装置。
技术介绍
消音器是空调设备中重要的辅助装置,基本由管形外壳组成,且管形壳体的两端均呈缩口状,即管形壳体中部的内径要大于管形壳体的两端内径,以通过截面积突然改变的方式使管内噪音得到衰减或反射回去。现有的空调消音器一般只是通过截面积的改变来实现消音的,消音效果不是很理想。
技术实现思路
本专利技术的目的是针对现有的技术存在上述问题,提出了一种高效消音装置,解决的技术问题是如何提高消音效果。本专利技术的目的可通过下列技术方案来实现:一种高效消音装置,包括呈圆管状的外壳,且外壳的左、右两端均呈缩口状,其特征在于,所述的外壳的左、右两端内分别固定有圆板一和圆板二,且圆板一的侧壁与外壳的内侧壁之间形成密封,圆板一和圆板二分别沿外壳的轴向贯穿开设有进气口和出气口,所述的外壳内还设有呈圆管状的连接管,且连接管、外壳、圆板一和圆板二四者的中心轴线共线,连接管的左、右两端分别呈敞开状和封闭状,且连接管的左、右两端分别与圆板一和圆板二相固连,所述的进气口与连接管的内腔连通,且出气口与连接管错开设置,连接管的侧壁上贯穿开设有使连接管的内腔与外壳的内腔连通的出气槽,出气槽有多个且均呈直条状,所述的出气槽的长度沿外壳的轴向延伸,所述的连接管内填充有吸音棉,所述的连接管的外径与外壳中部的内径之比小于三分之一。工作过程如下:气体由外壳的左端进入,并穿过进气口进入到连接管内与吸音棉接触,接着气体通过出气槽排入到外壳内,并最终由出气口排出。气体先排入到连接管内与吸音棉接触,以有效吸收气体所携带的噪音;其次,通过设置连接管的外径 ...
