1.多管环流式旋风除尘器(CN2271933Y) 本实用新型的目的是提供一种结构紧凑、合理、效率高的环流式旋风除尘器。其特征为:分离部分由旋风管、排风管组成,除尘部分主要由筒体、隔板、惯性分离器、回流风箱、回流风管组成,它们与进口风罩、进口风管、旋风管组成环路。除尘效率达到98％,既具现有旋风除尘器的优点,又无湿式除尘的二次污染,是可取代现有旋风除尘器的理想除尘装置。2.加压成型的带孔混凝土制品模具
1. Multi-cyclone cyclone dust collector (CN2271933Y) The purpose of the utility model is to provide a cyclonic cyclone dust collector with compact structure, reasonable and high efficiency. Its features are: the separation part is composed of cyclone tube and exhaust tube, and the dust removal part is mainly composed of cylinder body, partition plate, inertial separator, return wind box and return air tube. They are composed of inlet wind shield, inlet wind tube and cyclone tube. Loop. The dust removal efficiency reaches 98%, which not only has the advantages of the existing cyclone dust collector, but also does not have the secondary pollution of the wet dust removal. It is an ideal dust removal device that can replace the existing cyclone dust collector. 2. Press-formed perforated concrete molds
