The dust removal device comprises a dust hopper provided with a gas inlet, a box body provided with a gas outlet and a filter bag, and a gas spraying device, wherein the dust hopper is connected with the box body, the gas spraying device comprises a gas storing tank and a gas pipe communicated with the gas storing tank through a valve, the gas discharging end of the gas pipe faces to the filter bag, the dust removal device further comprises a control part for periodically controlling the opening and closing of the valve; with the adoption of the technical scheme, the technical problems can be effectively solved.

Description

A kind of deduster
Technical field
The utility model belongs to technical field of chemical, relates to a kind of deduster, and this deduster is removed dust in the gas by filter bag, and its application is extensive, for example, a kind of deduster described in the utility model can be used for the dedusting to fire coal boiler fume.
Background technology
Coal-burning boiler is before flue gas is carrying out the desulfurization processing, particulate matter in the flue gas (dust) need be removed, existing deduster generally adopts filter bag to filter particulate matter in the flue gas and realizes dedusting to flue gas, lasting feeding along with flue gas, particulate matter in the filter bag can be cumulative, need deashing, otherwise can influence filter effect.
Yet the general particle of regularly removing in the filter bag of existing deduster, should be noted that, in the actual production practice, the size of the amount of the flue gas of feeding deduster is indefinite in unit interval, also be that the stackeding speed of particulate matter is indefinite in the filter bag, timing can not guarantee timely particulate matter to be removed to the removing that filter bag carries out particulate matter, for example, when the stackeding speed of particulate matter in filter bag too fast, then when carrying out the removing of particulate matter, the resistance of filter bag is excessive, and filter bag has been caused destruction.
The utility model content
Technical problem to be solved in the utility model is that existing deduster can not in time be removed the particulate matter on the filter bag, causes efficiency of dust collection to reduce, and influences the problem of life of bag filter, and provide a kind of deduster at this problem.
The utility model solves the problems of the technologies described above by the following technical programs:
A kind of deduster, comprise the ash bucket that is provided with gas feed, the casing that is provided with gas vent and filter bag and air jet system, described ash bucket is connected with casing, described air jet system comprises air accumulator and the tracheae that is communicated with by valve with air accumulator, the exhaust end of tracheae is characterized in that towards filter bag described deduster also comprises the control assembly of regular by-pass valve control switch.
Particulate matter is in the size of the accumulation degree of filter bag and the power of filter bag that flue gas imposes on, under the constant situation of flue gas flow is proportional, adopt said structure, opening and closing valve that can be regular, thereby in time open valve by control assembly, Compressed Gas with air accumulator is removed the particulate matter that concentrates on the filter bag, guarantees the efficiency of dust collection of deduster, and prolongs the life-span of filter bag.
The utility model has also adopted following technical scheme:
Described casing is provided with the passage that is communicated with gas feed and gas vent, and described passage is provided with cuts apart slot passage, that supply filter bag to insert;
Described deduster also comprises lift cylinder, and described passage is provided with closed channel, the air door that is connected with lift cylinder, and described lift cylinder is connected with control assembly;
Filter bag is provided with filtering surface, and the exhaust end of described tracheae is positioned at the side of filter bag with respect to filtering surface;
Described valve is the pulse valve, and control assembly is a pulse control instrument.
Description of drawings
Fig. 1 is the structural representation of the described a kind of deduster of embodiment;
Fig. 2 is the plan structure schematic diagram of the described a kind of deduster of embodiment.
The specific embodiment
Embodiment
See Fig. 1 and Fig. 2, a kind of deduster comprises the casing, ash bucket 6 and the air jet system that are divided into upper box 9 and middle casing 4, and ash bucket 6 is connected with upper box 9 by middle casing 4.
Ash bucket 6 tops are provided with the gas feed 5 that enters for flue gas, and middle casing 4 tops are provided with the gas vent 7 of discharging for flue gas, are provided with 6 path 10s that are communicated with gas feed 5 and gas vent 7 in the middle casing 4, and each path 10 is isolated each other by conduit wall.
Each path 10 is equipped with cuts apart slot path 10, that supply filter bag to insert, and generally, filter bag is fixed by corresponding filter bag frame 1, and inserts slot by filter bag frame 1, and is certain, and when design, filter bag frame 1 and slot should seal.Adopt such structure, make the operation of changing filter bag become very simple, the filter bag of breakage is extracted out from slot, insert new filter bag then and can finish.
Simultaneously, described deduster also comprises lift cylinder (Fig. 1 and Fig. 2 are all not shown), described path 10 is provided with closed channel 10, the air door 11 that is connected with lift cylinder, described lift cylinder is connected with control assembly, being provided with of air door 11 mainly is for when filter bag is carried out deashing, can temporary close passage by filter bag, make deashing process not be subjected to the influence of flue gas ash removal.
Since be provided with 6 path 10s that are communicated with gas feed 5 and gas vent 7 in the middle casing 4, corresponding, need 6 filter bags to insert respectively in the above-mentioned path 10, and 6 air doors 11 that are used for sealing respectively above-mentioned path 10 are arranged.
And be positioned at the air jet system of upper box 9, be used for filter bag is carried out deashing, this air jet system comprises air accumulator 2, be responsible for 3 and 6 tracheaes 8 (the corresponding filter bag of each tracheae), be equipped with valve 12 on each tracheae, each tracheae all is communicated with air accumulator 2 by being responsible for 3, Compressed Gas in the air accumulator 2 can be replenished by the compressed gas import that is arranged on the air accumulator 2, the exhaust end of each tracheae is towards the filter bag that is provided with filtering surface, for the present embodiment, the exhaust end of each tracheae is positioned at the side of filter bag with respect to filtering surface, thereby realize oppositely blowing filter bag, strengthen the effect of deashing.
As for the valve 12 that is arranged on the tracheae 8, can be the pulse valve, and control assembly can be pulse control instrument (Fig. 1 and Fig. 2 is all not shown), the control impuls valve that this pulse control instrument can be regularly and the running of lift cylinder.
Whole deduster by stent support, for the technical staff safeguards the convenience of air jet system, can extra setting leads to the stair 13 of upper box 9.
During use, close the dust export of ash bucket bottom, the flue gas that coal-burning boiler is produced feeds the gas feed 5 that is arranged on the ash bucket top, filter bag in passage filters, and finally discharges from gas vent, in the process of filter bag accumulation dust, regularly by pulse control instrument control impuls valve and lifting arm, the deashing operation is in time carried out, and the dust that obtains falls into ash bucket through path 10, and discharges by dust export.
