Description
Technical field
The utility model relates to agglomerating plant technical field, in particular to a kind of sintering tiny structure igniters.
Background technique
Currently, sintering process is the indispensable process of iron and steel enterprise, qualified raw material can be provided to smelt iron, be needed in sintering
By bellows increase certain negative pressure in pallet bottom to promote the bed of material full combustion on top, in entire sintering process
The pressure difference of several bellows is smaller, generallys use high negative pressure sintering.But within sintering ignition stage or the first two bellows
There is very big harm using high negative pressure, one is part coal gas has little time burning just by sucking flue by force when igniting, make
It is insufficient at gas-fired, cause top bed of material moisture to be forced sedimentation and lower layer the second is negative pressure is excessive, leads to lower part material mistake
Wet, so that entire bed permeability decline, the third is a large amount of high wind is pumped in ignition phase, being sintered, total exhausting amount is constant
In the case where subsequent bellows air quantity reduce, the effective wind rate for oxygen of filling a vacancy is insufficient, the waste of effective wind rate is caused, the fourth is causing to give birth to
Expect more, height of returning mine, and then influences yield.
Utility model content
The technical problems to be solved in the utility model is to overcome the defect of above-mentioned technology, provides a kind of sintering tiny structure point
Fiery device, the tiny structure of simple, the adjustable bellows of structure.
In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of sintering tiny structure igniting dress
It sets, including bellows, the main gas tube being connected on bellows, equipped with several hang plates for stopping solid particle, institute in the bellows
It states side of the hang plate under and is equipped with the level-one cinder box for collecting solid particle, the level-one cinder box is connected to bellows, and described one
The bottom of grade cinder box is equipped with level-one discharge gate, and baffle is equipped between the bellows and level-one cinder box, and the bellows bottom is equipped with two
The side of second level cinder box is arranged in grade cinder box and second level discharge gate, the main gas tube, and the main gas tube is equipped with main air valve,
The main air valve controls the tiny structure of inner bellows by adjusting aperture, is equipped between the second level cinder box and main gas tube standby
With gas-guide tube, the spare gas-guide tube is equipped with spare air-valve.
As an improvement, the bellows are made of material resistant to high temperature.
As an improvement, the spare air-valve is normally closed solenoid valve.
The utility model compared with prior art the advantages of be: can be carried out under tiny structure when igniting, prevent coal gas
It burns insufficient phenomenon, and the entire bed of material does not have excessive moistening layer, ensure that whole gas permeability, sintering index are improved, returned mine
Few, yield is high；Setting hang plate is dusted, and because hang plate and solid particle gravity enter level-one cinder box, is effectively prevent
The blocking of pipeline clears up internal deposit by discharge gate；Bellows tiny structure can be adjusted by air-valve, adaptability
By force；Spare gas-guide tube guarantees that bellows will not lead to break-off because of maintenance of equipment when main gas tube breaks down.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of sintering tiny structure igniter of the utility model.
It is as shown in the figure: 1, bellows, 2, hang plate, 3, baffle, 4, level-one cinder box, 5, level-one discharge gate, 6, spare gas-guide tube,
