Description
Technical field
The present invention relates to the dust collection method in the production process of a kind of metallurgical briquetting ore deposit, especially a kind of dust pelletizing system of chain grate drive end unit.
Background technology
In the production process of metallurgy industry pellet, qualified green-ball on chain grate machine lathe, then completes the intensification of green-ball, drying, preheating, oxidizing process by blasting drying period, down-draft drying zone, preheating section by wide adhesive tape cloth.The shortcoming that this drum one is taken out in conjunction with drying process is that tail post environment is comparatively severe, and particular problem is: the dust pollution of (1) tail dust is larger.First when green-ball enters drum dry section (180 DEG C ~ 250 DEG C) at chain grate drive end unit by environment temperature, under air blast effect, hot gas penetrates the bed of material from the bottom to top to green-ball thermal dehydration, produce primary waste gases discharge from diffusing chimney, but petticoat pipe in due to positive pressure, part hot waste gas also from the tail bed of material and barricade end opening space excessive in a large number, produce dust, cause bad environments, hot gas pollutes, and ambient temperature rises, and has both affected production and also there is potential safety hazard to workman's production operation simultaneously; (2) tail hyperthermia radiation is seriously polluted, namely there is the temperature difference in reverse-running section and bearing material section, when material enters chain grate apparatus for forced section (180 DEG C ~ 250 DEG C) by normal temperature, equally due to the change of temperature, in pelletizing, moisture becomes dusty gas and emerges from chain grate drive end unit, has a strong impact on environment.Simultaneously the fluctuations of this temperature also can reduce service life of equipment (the mainly miniature deformation such as little axle, backhaul expects scraper etc. clearly), a small amount of steam simultaneously in environment enters lower layer space, repeatedly contacts with the structural member of once high temperature, also can affect the life-span of parts, increase maintenance workload.The gradient simultaneously also directly entering dry section (180 DEG C ~ 250 DEG C) variations in temperature of chain grate machine drum from normal temperature due to qualified green-ball is excessive, causes balling-up quantity of return mines to strengthen, affects production efficiency.These problems annoying produced on-site always, and especially after industry standard improves dedusting standard, this situation is badly in need of solving.Taking out in conjunction with drying process impact on environment to reduce drum one as far as possible, being necessary to employ new technology to take out drum one and improving in conjunction with drying process.
Summary of the invention
There is provided a kind of to calculate in machine single-revolution kiln pelletizing production at iron and steel enterprise's chain, chain grate machine tail dust can be improved, high temperature pollutes, save the dust pelletizing system of the chain grate drive end unit of the energy.
The object of the invention is to be achieved through the following technical solutions.
According to the dust pelletizing system of chain grate drive end unit of the present invention, a kind of dust pelletizing system of chain grate drive end unit, comprises chain grate machine, and the chain grate drive end unit return mechanism be made up of reverse-running section under reverse-running section on chain grate drive end unit and chain grate drive end unit, is characterized in that
Described chain grate drive end unit return mechanism is provided with the overall dedusting seal closure of chain grate machine tail, at the control valve that the overall left and right sides, dedusting seal closure top of described chain grate machine tail is connected with exhausting dust suction interface, exhausting dust sucting pipeline I and is arranged on exhausting dust sucting pipeline I, described exhausting dust sucting pipeline I is connected with the pipeline of bonnet blower fan; Be provided with the exhausting dust sucting pipeline II of band control valve at the middle part of the overall dedusting seal closure of described chain grate machine tail, described exhausting dust sucting pipeline II is connected with plant environment deduster;
Reverse-running section is provided with chain grate machine tail sealing bellows dust arrester under described chain grate drive end unit, described chain grate machine tail sealing bellows dust arrester is by the depression dust-removing bellows being arranged on the overall bottom, the dedusting seal closure left and right sides of chain grate machine tail, depression dust-removing bellows connect therewith successively ash bin, ash-unloading tube and unloading valve formed, be provided with adhesive tape conveyor in described ash-unloading tube bottom, and be provided with peep hole at ash bin sidepiece.
The overall dedusting seal closure of described chain grate machine tail is the sealing cover body that steel plate is made, and is welded on tail framework.
Advantage of the present invention is:
Because the present invention is provided with the overall dedusting seal closure of chain grate machine tail and chain grate machine tail sealing bellows dust arrester at the main airborne dust point place of Lian Bi drive end unit mechanism, pipeline is utilized to be connected with extraneous air exhauster, thus formation subnormal ambient, and by regulating blast, air quantity ensures pick-up performance, do not need to increase too large investment, two place's dust pelletizing systems make up mutually, all linked with one another, thus can effectively stop high-temp waste gas excessive, improve tail environment between chain grate locomotive, and by increasing by one section one section chain grate machine tail sealing bellows dust arrester on equipment, the dry section of drum is utilized to shift to an earlier date through the hot waste gas of the bed of material green-ball that preheating enters the dry section of drum, ensure that the service life of equipment heat-resistant piece, reduce workman's maintenance, simultaneously mild temperature of charge gradient, improves quality of green pellets, reduces ripe ball quantity of return mines.
