Abstract

The utility model relates to a cyclone-bag composite dust collector, which comprises a cyclone dust collector and a bag dust collector. The cyclone dust collector is utilized as a primary dust collector, the bag dust collector is utilized as a secondary dust collector, according to conditions that the cyclone dust collector is small in volume and low in treatment air quantity, the cyclone dust collector is disposed at an inlet position of each chamber of the bag dust collector, and through optimizing arrangement of smoke flues, dust of smoke is removed via the cyclone dust collector at first and then removed by the bag dust collector. The cyclone dust collector has a primary dust removing function, and reduces dust concentration of inlets of the bag dust collector. Simultaneously, by expanding selecting range of materials of a filter bag, impulse dust cleaning frequency is reduced, service lives of the filter bag and an impulse valve are prolonged, and operation cost of the bag dust collector can be reduced greatly.

Description

A kind of whirlwind-Bu bag complex dust collector

Technical field

The utility model relates to a kind of gas-solid separating device, relates in particular to a kind of complex type dust remover that combines cyclone dust collectors and sack cleaner.

Background technology

Cyclone dust collectors and sack cleaner are to use wider dust arrester at present, cyclone dust collectors are to utilize swirling eddy to make the grit in the air-flow produce certain centrifugal inertial force, grit in the air-flow is in the motion of the effect following peripheral of centrifugal inertial force, fall to reaching the purpose of gathering dust after running into barrel, but the shortcoming of cyclone dust collectors is poor to the capacity gauge of fine powder.The operation principle of sack cleaner is that ash-laden gas passes through filtering material, makes grit be filtered, and filtering material captures coarse dust mainly by the inertial collision effect, captures grain dust mainly by diffusion and sieving actoion.Have a kind of electricity-bag compound type dust remover on the market, electric cleaner and sack cleaner carried out combination, but exist that floor space is big, power consumption is high and can not on-bne repair etc. defective.

The utility model content

The utility model is to provide a kind of complex type dust remover with cyclone dust collectors and sack cleaner combination, and (as the grinding system of band o-sepa powder concentrator, its gas dust content is up to 1000g/m can to satisfy requirement to high dustiness flue gas dust collection ³More than (mark), by national standard limit of smog release, exit concentration 50mg/m ³, efficiency of dust collection will reach 99.995%).Simultaneously, in view of cyclone dust collectors are handled the requirement of the little and high dust content flue gas of air quantity to the sack cleaner filter bag, the little advantage with the high efficiency of dust collection of sack cleaner of rationally comprehensive cyclone dust collectors volume has solved the defective of above-mentioned electricity-bag compound type dust remover effectively.

The technical scheme that the utility model adopted is: a kind of whirlwind-Bu bag complex dust collector comprises cyclone dust collectors and sack cleaner.Cyclone dust collectors are as the primary dust removing device, sack cleaner is as secondary ash collector, little and the little situation of processing air quantity according to the cyclone dust collectors volume, cyclone dust collectors are arranged at the entry position of every chamber of sack cleaner, arrange by optimizing the flue gas flue, make flue gas earlier through after the cyclone dust collectors dedusting, again by the sack cleaner dedusting.Cyclone dust collectors play the effect of primary dust removing, have reduced sack cleaner inlet dust content.Simultaneously,, reduce the pulse dust cleaning frequency, prolong filter bag and pulse valve service life, can reduce sack cleaner operating cost greatly by increasing the scope of choosing of filter bag material.

This mechanical and hydraulic combined dust utensil have handle that air quantity is big, efficiency of dust collection is high, but compact conformation on-bne repair, investment are little, easy care, advantage such as applied widely.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

As depicted in figs. 1 and 2, wind described in the utility model-Bu bag complex dust collector comprises as the cyclone dust collectors 3 of primary dust removing device with as secondary ash collector getting sack cleaner 2.Inlet smoke box 1, cyclone dust collectors 3 and sack cleaner 2 are communicated with successively, little and the little situation of processing air quantity according to cyclone dust collectors 3 volumes, cyclone dust collectors 3 are arranged at the entry position of sack cleaner every chambers 2, arrange by optimizing the flue gas flue, make flue gas earlier through after cyclone dust collectors 3 dedustings, again by sack cleaner 2 dedustings.

The utility model is not limited to the foregoing description; to those skilled in the art, any conspicuous improvement that the foregoing description of the present utility model is made or change can not exceed the embodiment of the present utility model that only illustrates by way of example and the protection domain of claims.

Claims

1. whirlwind-Bu bag complex dust collector is characterized in that: described complex dust collector comprises that described cyclone dust collectors are arranged at the entry position of every chamber of sack cleaner as the cyclone dust collectors of primary dust removing device with as the sack cleaner of secondary ash collector.
