Abstract

The utility model relates to a multistage efficient cyclone dust removing set. The utility model is characterized in that two or more than two cyclone dust removers are connected in parallel to form a first stage cyclone dust remover, four or more than four cyclone dust removers are connected in parallel to form a secondary, a third or multistage cyclone dust remover, and all the cyclone dust removers are connected in series to form a multistage efficient cyclone dust remover set. The utility model can be widely used in various dust removing systems needing higher dust removing efficiency, lower dust emission concentration or smaller dust particle diameter and other kinds of environmental protection equipment.

Description

Efficient cyclone duster set

The utility model relates to a kind of dust arrester, particularly a kind of multi-stage, efficient cyclone dust removal unit.

Cyclone dust collectors commonly used both at home and abroad at present generally belong to the single-stage deduster, and to the dust of 10～20 μ m, efficient only is about 90%, and dust removing effects is very undesirable.And this class deduster is to below the 10 μ m or littler dust, the dust removing effects extreme difference.Though these class cyclone dust collectors also can be used as the first order in the multistage rotary dust collector, volume is bigger, and dust removing effects is relatively poor.(referring to " industrial ventilation " book chapter 4, China Construction Industry Press, in December, 1985).Although people can utilize effect of inertia to improve efficiency of dust collection, reduce equipment size, effective capture dust granules is dropped to below the 10 μ m, but for particle diameter is the particle of 10 μ m, its classification efficiency only reaches 80%(and compiles " air pollution control technique handbook referring to (U.S.) S. CALVER top grade, Maritime Press, 1987, chapter 13).Obviously, still be difficult to satisfy the needs of actual use and environmental protection.

The purpose of this utility model is the efficient cyclone dedusting unit of a kind of multi-stage combination of design, and its granulometric range that effectively captures extends to about 1 μ m, and the efficiency of dust collection of general dust is brought up to more than 99%.

Can adopt following structure to realize the purpose of this utility model: cyclone dust collectors identical or different more than two are together in parallel as the one-level cyclone dust collectors; Again that four or more is identical or different cyclone dust collectors are together in parallel as second cyclone dust extractor; Multicyclone dust collectors such as three grades, level Four can also be arranged as requested.Cyclone dust collectors at different levels adopt annular radial combination when in parallel, make the airflow route that enters each cyclone dust collectors in full accord.At last cyclone dust collectors at different levels are together in series, just constitute multi-stage, efficient cyclone dust removal unit.The utility model can be set to suction-type or extrusion formula according to actual requirement, can also the first order suck, and the second level extrudes.Series connection between at different levels can be adopted top series process, series process or go up down series process up and down.

Accompanying drawing 1 is the front view of the utility model (top tandem type); Accompanying drawing 2 is planes of the present utility model; Accompanying drawing 3 is front views of this practicality new (tandem type up and down).The contrast accompanying drawing elaborates to the utility model below.As shown in Figure 2: radial ringwise evenly being parallel together of two or more cyclone dust collectors (4) constituted first order cyclone dust collectors, again radial ringwise evenly being parallel together of four or more cyclone dust collectors (4) constituted second level cyclone dust collectors, the third level, the fourth stage etc. are so combination also; Again cyclone dust collectors at different levels are cascaded with pipeline (9), constitute multi-stage, efficient cyclone dust removal unit, (shown in accompanying drawing 1 and accompanying drawing 3).The efficient cyclone dedusting unit of so also series connection formation, its course of work is as follows: dusty gas is entered by pipeline section (1) in the air inlet air chest (2) of first order cyclone dust collectors, and air-flow is assigned to equably through deduster interface (3) and respectively makes up on the cyclone dust collectors (4).Dust is focused on by ash bucket (5) after cyclone dust collectors (4) separate.Gas behind the primary purifying is imported in the exhaust plenum chamber (8) through exhaust plenum chamber interface (7) by one-level cyclone dust collectors exhaust volute (6), enters in the second cyclone dust extractor air inlet air chest (10) through pipeline (9) again.The primary purifying air-flow is assigned to equably through second cyclone dust extractor interface (11) and is respectively made up in the cyclone dust collectors (12), and after it separated once more, dust was focused on by second cyclone dust extractor ash bucket (13).Double purification gas is discharged after plenum chamber interface (15) imports exhaust plenum chamber (16) by second cyclone dust extractor exhaust volute (14).Still undesirable as gas through double purification, also can adopt three grades, level Four or more multi-stage, efficient cyclone dust removal unit further handle, but structural principle and operation principle and two-stage efficient cyclone dedusting unit are identical.

Compared with the prior art, outstanding advantage of the present utility model is, adopt the in parallel and multicyclone dust collector series connection of a plurality of cyclone dust collectors, general dusty gas efficiency of dust collection after repeatedly purifying is reached more than 99%, base is to approaching 100%, and effectively captures the dust scope and may extend into micron order.The utility model has also been given full play to the characteristics that cyclone duster structure is simple, volume is little, easy to maintenance, can adopt fixture or mobile device respectively according to the requirement of different disposal air quantity in actual use, and its suitable application area is expanded greatly.In addition, structural principle of the present utility model is also irrelevant with the structural parameters of cyclone dust collectors, thereby can be suitable for any combination of multiple cyclone dust collectors.The utility model can be widely used in needing among all kinds of dust pelletizing systems of higher efficiency of dust collection, low dust emission concentration or less dust size and in other environmental protection equipments.
