Abstract
The invention relates to a dust removing method in the production process of metallurgical pellets, in particular to a dust removing system of a chain grate machine tail part. The dust removing system comprises a chain grating machine tail part mechanism with a chain grate machine wheel and a chain grate machine tail wheel return device; the dust removing system is characterized in that a machine tail seal cover is arranged on the chain grate machine tail part mechanism; chain grate machine tail wheel return segment dust removing devices are arranged on the upper part of the machine tail seal cover; an overall chain grate machine tail dust removing device is arranged in the middle part of the machine tail seal cover; and a tail sealing wind box dust removing device of the chain grate machine is arranged at the end part of the lower return of the chain grate machine tail. According to the dust removing system provided by the invention, as the chain grate machine tail wheel return segment dust removing devices are arranged at the three main dust-raising spots of the chain grate machine tail mechanism, and are connected with external exhaust fans by pipelines, thereby forming a negative pressure environment; the three dust removing systems are compensated to one another and are linked with one another, so that the high temperature waste gas can be effectively prevented from overflowing, the tail machine environment of the chain grate machine workshop can be improved, the service life of the heat resistant parts of the equipment can be ensured; and moreover, the temperature gradients of the materials are smoothed, and the mine return quantity of the cured pellets can be reduced.
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 to chain grate machine lathe, is then finished intensification, drying, preheating, the oxidizing process of green-ball by wide adhesive tape cloth by blasting drying period, down-draft drying zone, preheating section.The shortcoming that this drum one is taken out in conjunction with drying process is that tail post environment is comparatively abominable, and particular problem is: the dust pollution of (1) tail dust is larger.At first when green-ball when chain grate drive end unit is entered drum and is done section (180 ℃～250 ℃) by environment temperature, under the air blast effect, hot gas penetrates the bed of material from the bottom to top to the green-ball thermal dehydration, the main waste gas that produces discharges from diffusing chimney, but in the petticoat pipe because positive pressure, part hot waste gas also slave tailing layer and barricade end opening space is excessive in a large number, produce dust, to cause environment abominable, hot gas pollutes, and temperature rises all around, has both affected production and simultaneously also there has been potential safety hazard in workman's production operation; (2) the tail hyperthermia radiation is seriously polluted, be that reverse-running section and bearing material section exist the temperature difference, when material enters chain grate apparatus for forced section (180 ℃～250 ℃) by normal temperature, same because the variation of temperature, moisture becomes dusty gas and emerges from chain grate drive end unit in the pelletizing, has a strong impact on environment.It (mainly is the miniature deformations such as little axle that the fluctuations of this temperature of while also can reduce service life of equipment, scraper etc. is expected clearly in backhaul), simultaneously a small amount of steam in the environment enters lower layer space, repeatedly contacts with the structural member of high temperature once, also can affect the life-span of parts, increase maintenance workload.Also to do the gradient of section (180 ℃～250 ℃) variations in temperature excessive because qualified green-ball directly enters chain grate machine drum from normal temperature simultaneously, causes the balling-up quantity of return mines to strengthen, and affects production efficiency.These problems are perplexing produced on-site always, and especially after industry standard improved the dedusting standard, this situation was badly in need of solving.Take out in conjunction with the impact of drying process on environment in order to reduce drum one as far as possible, be necessary to employ new technology drum one taken out in conjunction with drying process and improve.
Summary of the invention
Provide a kind of and calculate in the machine single-revolution kiln pelletizing production at iron and steel enterprise's chain, can improve chain grate machine tail dust, high temperature pollution, the dust pelletizing system of saving the chain grate drive end unit of the energy.
The objective of the invention is to be achieved through the following technical solutions.
Dust pelletizing system according to chain grate drive end unit of the present invention, comprise the chain grate drive end unit mechanism with chain grate tail wheel and chain grate tail wheel return facilities, it is characterized in that being provided with the tail seal closure in chain grate drive end unit mechanism, chain grate tail wheel reverse-running section dust arrester is set on the top of described tail seal closure, the whole dust arrester of chain grate machine tail is set at the middle part of described tail seal closure, the end of backhaul arranges chain grate machine tail sealing bellows dust arrester under described chain grate tail
Described tail seal closure is that steel plate is made a sealing cover body, is welded on the tail framework, and its sealing cover body is with chain grate drive end unit mechanism integral sealing;
Described chain grate tail wheel reverse-running section dust arrester is comprised of the exhausting interface, the exhausting dust sucting pipeline I that are connected with the left and right sides, tail seal closure top and the control valve that is arranged on the exhausting dust sucting pipeline I, and described exhausting dust sucting pipeline I is connected with the pipeline that enters the bonnet blower fan;
The whole dust arrester of described chain grate machine tail is comprised of the exhausting dust sucting pipeline II that is connected with tail seal closure middle part and the control valve that is arranged on the exhausting dust sucting pipeline, and described exhausting dust sucting pipeline II is connected with plant environment deduster deduster;
Described chain grate machine tail sealing bellows dust arrester is by the depression dust-removing bellows that are arranged on bottom, the tail seal closure left and right sides, ash bin, ash-unloading tube and the unloading valve of the connection of depression dust-removing bellows form therewith successively, be provided with adhesive tape conveyor in described ash-unloading tube bottom, and be provided with peep hole at the ash bin sidepiece.
Advantage of the present invention is:
Because the present invention is provided with chain grate tail wheel reverse-running section dust arrester at three main airborne dust point places of chain grate drive end unit mechanism, the whole dust arrester of chain grate machine tail and chain grate machine tail sealing bellows dust arrester, utilize pipeline to link to each other with extraneous air exhauster, thereby formation subnormal ambient, and by regulating blast, air quantity guarantees pick-up performance, do not need to increase too large investment, three place's dust pelletizing systems remedy mutually, all linked with one another, thereby can effectively stop high-temp waste gas excessive, improve tail environment between chain grate locomotive, and by shifting to an earlier date the green-ball that preheating enters the dried section of drum at dried section hot waste gas that passes the bed of material of one section negative pressure bellows utilization drum of equipment increase, guarantee the service life of equipment heat-resistant piece, reduced workman's maintenance; Simultaneously mild temperature of charge gradient improves quality of green pellets, reduces ripe ball quantity of return mines.
