Abstract

The utility model relates to a multi-pipe cyclone dust collector. The utility model has the technical proposal that a plurality of cyclones (3) are arranged on the concentric circumference in a cyclonic parent (2); each air inlet pipe (5) of the cyclone (3) is communicated with an air collecting pip (6) of the cyclonic parent (2). The dust-laden air flow firstly enters into the cyclonic parent (2) from a main inlet pipe to proceed with the dedusting of the first grade, and then enters into each cyclone (3) to proceed with the secondary dedusting through a plurality of air inlet pipes (5) around the air collecting pip (6). This scheme ensures that the wind pressure of each cyclone is balanced. The structure of the dust collector is compact, the floor area and the consumption of the rolled steel are small, and the dust collection efficiency is high. The utility model can be widely used for the purification of various drying flue gas.

Description

Efficient primary-auxiliary type multicyclone

The utility model relates to a kind of multicyclone.

Cyclone dust collectors are to be used for the most a kind of dust arrester of gas cleaning at present.For satisfying needs, often adopt the sub-parallel way of a plurality of whirlys, i.e. multicyclone than opium gas disposal amount.Whirlwind of multicyclone has two kinds of forms: axial-flow type and cut streaming.Because the axial-flow type efficiency of dust collection is lower, has been tending towards superseded at present.The basic structure of cutting the streaming multicyclone is at a plurality of streaming whirlwind of cutting of the indoor layout of gravitational settling, its major defect is: deduster body floor space is big and steel consumption is big: the efficiency of dust collection as the gravity settling chamber of primary dust removing is very low, usually efficient is lower than 30%, and the gross efficiency of whole deduster is lower than 90%; Be difficult to realize that each whirlwind equates in pressure balance and intake, thereby cause each whirlwind under nominal situation, not move.

Task of the present utility model provides and a kind ofly can reduce volume significantly and reduce steel consumption, guarantee that the sub-pressure balance of each whirlwind, efficiency of dust collection reach the multicyclone more than 90%.

For finishing above-mentioned task, the technical scheme that the utility model is taked is: whirlwind is installed in whirlwind mother's the abdomen.

The sub-air inlet pipe of each whirlwind is distributed in around the female wind converging tube of whirlwind, and the air inlet pipe of each whirlwind communicates with whirlwind mother's wind converging tube.

Owing to adopt technique scheme, the utility model not only increases substantially the primary dust removing efficient of multicyclone, total efficiency of dust collection of whole deduster is reached more than 90%, reduce the volume of cyclone dust collectors body effectively, and the blast of each whirlwind and air quantity are equated.This deduster can be widely used in the udst separation of various flue gases.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A profile of Fig. 1.

The basic structure of primary-auxiliary type multicyclone is installed on several whirlwind [3] in whirlwind mother [2] abdomen as shown in Figure 1.Whirlwind [3] be distributed in wind converging tube [6] around, the air inlet pipe [5] of whirlwind [3] communicates with the wind converging tube [6] of whirlwind mother [2], the ash discharging pipe [7] of whirlwind [3] is positioned at the bottom of whirlwind [3], and the conical section that passes whirlwind mother [2] communicates with total ash bucket [8].Total ash bucket [8] is positioned at the lower end of deduster body.The course of work of this deduster is: dust-contained airflow enters whirlwind mother [2] through Fig. 1, total inlet pipe [1] shown in Figure 2, utilize top-down swirling eddy to the inertial collision effect of the dust in dust generation centrifugal force and the swirling eddy, thicker dust is separated from air-flow whirlwind [3].The dust of separating falls into total ash bucket [8] in downstream and gravity effect lower edge whirlwind mother's [2] inwall downslide.The gap of crossing between each whirlwind [3] through the air communication behind whirlwind mother [2] one-time dedusting flows into the female wind converging tube [6] of whirlwind, air-flow enters each whirlwind [3] by being connected wind converging tube [6] air inlet pipe [5] on every side then, and dust-contained airflow carries out final dusting in whirlwind [3].Dust under removing glides along the inwall of whirlwind [3], also falls into total ash bucket [8] through ash discharging pipe [7].Purified gas is after the sub-blast pipe of whirlwind [4] is discharged the deduster body.

Claims

1. a multicyclone is characterized in that whirlwind [3] of this deduster is installed in the abdomen of whirlwind mother [2].

2. deduster according to claim 1 is characterized in that the air inlet pipe [5] of each whirlwind [3] communicates with the wind converging tube [6] of whirlwind mother [2].
