Abstract
The utility model relates to a two-flue ignition switching device of a sintering machine, which belongs to the technical field of sintering equipment. The dual-flue ignition switching device of the sintering machine comprises a desulphurization flue and a non-desulphurization flue, wherein the desulphurization flue is connected with a first ignition ventilation delivery pipe, and the non-desulphurization flue is connected with a second ignition ventilation delivery pipe. A number-one emergency delivery pipe is arranged between the desulphurization flue and the second ignition ventilation delivery pipe. A number-two emergency delivery pipe is arranged between the non-desulphurization flue and the first ignition ventilation delivery pipe. A number-one butterfly valve is installed in the desulphurization flue, a number-two butterfly valve is installed in the non-desulphurization flue, a number-three butterfly valve is installed in the number-one emergency delivery pipe, and a number-four butterfly valve is installed in the number-two emergency delivery pipe. A number-one flowmeter is installed on the desulphurization flue. A number-two flowmeter is installed on the non-desulphurization flue. The two-flue ignition switching device of the sintering machine has the beneficial effects that through the communication of the emergency delivery pipes, the ventilation ignition can be realized by utilizing another single fan when a single main exhaust fan is malfunctioned, so that the continuity of the device in running can be guaranteed.
Description
Technical field
The novel agglomerating plant technical field that belongs to of this use, specifically a kind of sintering machine twin flue igniting switching device shifter.
Background technology
Sintering machine flue igniting bellows are arranged on pallet bottom, and in order to sinter mixture exhausting, bed of material surface forms micro-negative pressure, sinter bed surface fuel are lighted and the device of burning downwards.Igniting exhausting system only can corresponding fixing single blower fan, flue and bellows at present.When under non-de-flue main exhauster malfunction, the head bellows that igniter is corresponding will be in halted state, igniter sinter bed below cannot produce suitable igniting negative pressure, igniting operation cannot normally be carried out, sintering main line will stop production, carry out great risk to supporting with it blast furnace operation feed strip, chromic trouble will cause blast furnace staying even to stop production.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of sintering machine twin flue igniting switching device shifter, with the solution problem of de-flue main exhauster malfunction down-firing by no means.
The technical scheme of the utility model technical solution problem is:
A kind of sintering machine twin flue igniting switching device shifter, comprises de-S flue, non-de-S flue, on de-S flue, is connected with the first igniting exhausting carrier pipe, is connected with the second igniting exhausting carrier pipe on non-de-S flue.Between de-S flue and the second igniting exhausting carrier pipe, be connected with emergent carrier pipe No. one.Between non-de-S flue and the first igniting exhausting carrier pipe, be connected with emergent carrier pipe No. two.In de-S flue, butterfly valve is housed No. one, in non-de-S flue, butterfly valve is housed No. two, in an emergent carrier pipe, be equipped with in No. three butterfly valves, No. two emergent carrier pipes butterfly valve is housed No. four.
On de-S flue, flowmeter is installed No. one.
On non-de-S flue, flowmeter is installed No. two.
The beneficial effects of the utility model are: by the connection of emergent carrier pipe, just can be under separate unit main exhauster malfunction, and realize with another single blower fan exhausting igniting, ensure the continuous operation of equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: de-S flue 1, non-de-S flue 2, the first igniting exhausting carrier pipe 3, the second igniting exhausting carrier pipe 4, emergent carrier pipe 51, No. two emergent carrier pipes 52, butterfly valve 61, No. two butterfly valves 62, No. three butterfly valves 63, No. four butterfly valves 64, flowmeter 71, No. two flowmeters 72.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of sintering machine twin flue igniting switching device shifter, comprises de-S flue 1, non-de-S flue 2, on de-S flue 1, is connected with the first igniting exhausting carrier pipe 3, is connected with the second igniting exhausting carrier pipe 4 on non-de-S flue 2.Between de-S flue 1 and the second igniting exhausting carrier pipe 4, be connected with emergent carrier pipe 51 No. one.Between non-de-S flue 2 and the first igniting exhausting carrier pipe 3, be connected with emergent carrier pipe 52 No. two.
In de-S flue 1, butterfly valve 61 is housed No. one, in described non-de-S flue 2, butterfly valve 62 is housed No. two, in a described emergent carrier pipe 51, be equipped with in No. three butterfly valves 63, described No. two emergent carrier pipes 52 butterfly valve 64 is housed No. four.On de-S flue 1, flowmeter 71 is installed No. one.On non-de-S flue 2, flowmeter 72 is installed No. two.
To take off S flue 1 as example, illustrate that the course of work of the present utility model describes.When de-S flue 1 normal work, No. three butterfly valves 63 and No. four butterfly valves 64 are all in closed condition, and butterfly valve 61, No. two butterfly valves 62 are in opening.A flowmeter 71 is without flow indication, and de-S flue 1 loss of ignition of representative, at this moment will close butterfly valve 61 No. one, make 63, No. two butterfly valves 62 of No. three butterfly valves simultaneously and remain on opening, and No. four butterfly valve 64 remains on closed condition.Thereby ensure that whole device continues operation.
