Efficient low-resistance cyclone and working method

Abstract

The invention belongs to the technical field of cement industrial production, and particularly relates to an efficient low-resistance cyclone and a working method thereof. The efficient low-resistancecyclone comprises an inlet air pipe, a volute body, an inner barrel, a cylinder body, an upper cone body and a lower cone body, wherein the inlet air pipe is arranged at an inlet of the volute body;the inlet air pipe is provided with an airflow inlet; the inner barrel is cylindrical, and the inner barrel and an airflow outlet are integrally welded in the volute body in a sleeved mode; the volutebody is of a three-center equal-height variable-angle volute structure formed by welding three arcs with different radii; a top cover is arranged at the top of the volute body; the airflow outlet isformed in the center of the top cover; the upper cone body and the lower cone body are sequentially connected below the cylinder body; and an outlet of the lower cone body is a discharging port. The efficient low-resistance cyclone and the working method thereof achieve the purpose that the resistance of the cyclone in a cement production line pre-decomposition system can still be greatly reducedon the premise that the separation efficiency is ensured, so that energy saving and consumption reduction are realized, and the resistance loss is lower than a common cyclone.

Description

technical field [0001] The invention belongs to the technical field of cement industry production, and particularly relates to a high-efficiency and low-resistance cyclone used in a pre-decomposition system of a new dry-process cement production line and a working method. Background technique [0002] At present, in the field of new dry process cement production technology, due to the state's emphasis on production capacity control and environmental protection, energy saving and consumption reduction are important goals pursued by enterprises. Reducing the resistance of the kiln tail preheater system and reducing the operating load of the high-temperature fan can effectively reduce its power consumption. Among them, the resistance of the kiln tail preheater mainly comes from the combined reconstruction of the multi-stage cyclone, so reducing the resistance of the cyclone at all levels can effectively achieve energy saving. [0003] The cyclone is a device that separates dus...
