Abstract
The utility model relates to a pulse bag dust collector with vacuum protection. The pulse bag dust collector with the vacuum protection comprises a support frame, a box body, a rail, a pulse injection pipeline system, a ladder stand, a rigid impeller feeding machine, a gate valve, a filter-bag, a cage frame and a by-pass line, wherein an air inlet of the box body is provided with an inlet air control valve, an air outlet of the box body is provided with an outlet air control valve, an ash hopper mouth is provided with the gate valve, a by-pass valve is installed inside the by-pass line, two ends of the by-pass line are respectively connected with an air inlet pipeline and an air outlet pipeline. The vacuum protection of the dust collector is characterized in that when the dust collecting is achieved by the pulse bag dust collector, the air inlet control valve is closed, then the air outlet control valve is closed and a vacuum state under which the inner pressure of the box body is less than 0.1 MP. The pulse bag dust collector with the vacuum protection is suitable for the chemical industry and the treatment works of the flue gas and dust with strong hydrophily, and has the advantages of being capable of effectively avoiding the corrosive damage on the dust collector caused by the hydrophilic flue gas and dust, and therefore the service life of the dust collector is prolonged.
Description
One, technical field
The utility model relates to a kind of pulse bag type dust collector, particularly relates to a kind of pulse bag type dust collector of vacuum protection.
Two, background technology
At present, in industrial smoke dust purification treatment facility, usually adopt pulse bag type dust collector.Pulse bag type dust collector need to utilize compressed air that filter bag is carried out pulse dust cleaning in running, and the dust on the filter bag is come off, to guarantee that deduster can work.At present after handling a lot of chemical industry waste gas, at the residual a large amount of extension dust of the inner meeting of pulse bag type dust collector, these exhaust gas dusts have hydrophily mostly, easily form water-fast hard scale after the suction, and stick on the filter bag, cause filter bag to stop up, cause efficiency of dust collection reduction or deduster malfunctioning; These hydrophilic dusts also have certain corrosivity, easily filter bag are caused in various degree corrosion, reduce life of bag filter, increase operating cost.
Three, summary of the invention
The purpose of this utility model is, a kind of pulse bag type dust collector of vacuum protection is provided, be intended to the pulse bag type dust collector dedusting complete after, make box house keep vacuum state, avoid the hydrophily exhaust gas dust that deduster is produced corrosion and damage.
For solving the problems of the technologies described above; technical solution of the present utility model is a kind of pulse bag type dust collector of vacuum protection; comprise the parts such as bracing frame, casing, railing, pulse jet pipeline system, cat ladder, rigid impeller feeding machine, push-pull valve, filter bag, cage, bypass line; it is characterized in that: described casing air inlet place arranges the air intake control valve; the air outlet place arranges the air-out control valve; ash quarrel place arranges push-pull valve, and by-passing valve is set in the bypass line.
Described bypass line two ends respectively with air inlet and air outlet pipeline connection.The vacuum protection of deduster is after the pulse bag type dust collector dedusting is complete, and the box house mineralization pressure is less than the vacuum state of 0.1MPa.
The advantage that the utlity model has: by air intake control valve, air-out control valve and push-pull valve are set, can effectively control flowing of flue gas, and guarantee the sealing of deduster inside; Pulse bag type dust collector with the inner vacuum state that keeps of pulse bag type dust collector, effectively completely cuts off obstruction and the corrosion and damage that the stronger dust of hydrophily causes filter bag after hours; Simultaneously, when deduster is started shooting, the cold air in the air inlet pipeline is directly discharged from bypass line, avoid cold air directly to enter and form dewfall in the dust collector box body, deduster is damaged.
This product has preferably vacuum protection ability, is applicable to the work for the treatment of of the stronger exhaust gas dust of chemical industry and hydrophily, can effectively avoid the hydrophily exhaust gas dust that deduster is produced corrosion and damage, prolongs the service life of deduster.

Fig. 3 is the utility model top view.
Be labeled as among the figure: 1 bracing frame, 2 inspection doors, 3 ash buckets, 4 air inlets, 5 air intake control valves, 6 casings, 7 pulse jet pipeline systems, 8 railings, 9 cat ladders, 10 air-out control valves, 11 air outlets, 12 push-pull valves, 13 rigid impeller feeding machines, 14 cages, 15 filter bags, 16 bypass lines, 17 by-passing valves.
Five, the specific embodiment
The present invention is described in further detail below in conjunction with embodiment, but not as the foundation of the present invention being done any restriction.
The pulse bag type dust collector of a kind of vacuum protection described in the utility model, its structure is supported by bracing frame 1 conduct, and is provided with cat ladder 9 in the deduster left side; Casing 6 bottoms are provided with two ash buckets 3 side by side, and ash bucket 3 is provided with inspection door 2, push-pull valve 12 and rigid impeller feeding machine 13 are equipped with in its bottom; Casing 6 left and right sides are respectively equipped with air outlet 11, air-out control valve 10, air inlet 4 and air intake control valve 5; Pipe-line system 7 is equipped with at casing 6 tops, and is provided with railing 8; Casing 5 inside also are provided with a plurality of cages 15 and filter bag 16; In the deduster main body outside, be provided with bypass line 16 and by-passing valve 17, bypass line 16 is interconnected air inlet 4 and air outlet 11.
Implementing the utility model vacuum protection is in dedusting after hours; carry out deashing 2～3 times by 7 pairs of filter bags of pulse jet pipeline system 15; after by rigid impeller feeding machine 13 dust stratifications in the ash bucket 3 being discharged behind the deashing; air intake control valve 5 and push-pull valve 12 time-delays 5～20s are closed; and keep blower fan to work; after air intake control valve 5 and push-pull valve 12 are closed; deduster inside is extracted into pressure less than 0.1MPa; close again blower fan; and close simultaneously air-out control valve 10, this moment, deduster inside just formed vacuum state.When deduster is started shooting, open first by-passing valve 17, behind blower fan work 30s～90s, open again wind control valve 5 and air-out control valve 10, close simultaneously by-passing valve 17, this moment, deduster began normal operation.
