Tangential flow type parallel cyclone separator

Abstract

The invention relates to a parallel cyclone separator. The parallel cyclone separator comprises a plurality of vertically arranged separation elements, and each of the separation elements is a tangential flow back type cyclone separator; the separation elements share a gas inlet pipe, the gas outlets of the separation elements are commonly connected with a public gas collection chamber, and the dust discharge holes of the separation elements are commonly connected with a public ash bucket; the gas inlet pipe is connected with a vertically arranged distribution pipe with a closed top end, and the bottom gas inlet end of the distribution pipe is connected with the gas inlet pipe; the distribution pipe is circumferentially provided with directional tapered outlets with the number same to the number of the separation elements, the separation elements are symmetrically arranged around the axial center of the distribution pipe, and each of the directional tapered outlets is connected with the gas inlet of the corresponding separation element; and the upper segment of the public ash bucket is cylindrical, and the lower segment of the public ash bucket is a back taper with big top and small bottom. The parallel cyclone separator can improve the distribution uniformity of gas flow entering the separating elements, and obviously inhibits the channeling back mixing problem among the separation elements in a public dust discharge chamber in order to improve the overall separation efficiency of the parallel separator.

Description

technical field [0001] The invention relates to a gas-solid separation device, in particular to a cut-flow parallel cyclone. Background technique [0002] Cyclone separator (hereinafter referred to as "cyclone") is a common gas-solid separation equipment, the existing single tangential flow cyclone 7' such as figure 1 , figure 2 As shown, it includes a core tube 71', a cylinder 72', a cone 73', an ash hopper 74', a dipleg 75', and a rectangular inlet 76'. When the dust-laden airflow a enters the cyclone 7' from the rectangular inlet 76', the airflow will change from linear motion to circular motion. Most of the swirling air flow spirals downward from the cylinder 72' along the wall of the device, and flows toward the cone 73', which is usually called an external swirling flow. The dust-laden airflow a drives the particles to rotate at the same time during the high-speed rotation. Since the density of the dust particles is much greater than that of the gas, the centrifuga...

Problems solved by technology

When this difference is large, it is easy to cause "channeling and back-mixing" in the public dust removal room, seriously affecting the overall performance of the parallel cyclone, and even making it invalid

When the existing parallel cyclone works normally, its overall separation efficiency is usually lower than that of a single separation element working independently under the same conditions
