Description
Technical Field
The invention relates to the technical field of dust removal of a circular cooler, in particular to an air suction dust removal device for a receiving point of a circular cooler.
Background
Sintered mineral aggregate after sintering machine burning can enter into the material receiving point region of the ring cooling machine through the guide chute, then transport forward along with the platform truck of the ring cooling machine, realize cooling in the in-process of transportation, in the cooling process of the ring cooling machine to sintered mineral aggregate, can produce the waste heat, for energy saving, can collect the waste heat and carry out waste heat utilization, wherein, the temperature of the sintered mineral aggregate that falls into the material receiving point department of the ring cooling machine is the highest, therefore, can set up the heat that the high temperature got the wind gap and is used for collecting the sintered mineral aggregate of material receiving point department at material receiving point department, and simultaneously, because sintered mineral aggregate is through the landing of guide chute to material receiving point department, consequently, material receiving point department can produce a large amount of raise dusts, in order to improve operational environment, can set up the dust removal and get the wind gap at material receiving point department, the raise dust that produces of material receiving point department is sucked away.
The high-temperature air taking port and the dedusting air taking port are both arranged on a smoke hood of the annular cooler, and the smoke hood is positioned above a trolley of the annular cooler, wherein the dedusting air taking port is arranged on the smoke hood between the two axial lines and the three axial lines of the annular cooler, and the dedusting air taking port is connected with a pipeline; the high-temperature air intake is arranged on the smoke hood between the three axis and the four axis of the circular cooler and is connected with the pipeline; the pipeline connected with the dust removal air intake port and the high temperature air intake port is in an air suction state, after the sintering mineral aggregate falls into a material receiving point, generated flying dust can be sucked away through the dust removal air intake port, and waste heat of the sintering mineral aggregate can be sucked away through the high temperature air intake port and enters the waste heat boiler to be distributed to the waste heat power generation device, however, during field analysis and debugging, the fact that the actual inlet hot air parameter of the waste heat boiler has a larger deviation with the theoretically reached inlet hot air parameter is found, the deviation between the entering hot air quantity and the temperature of hot air is 10-30 percent different, the reason is that when the dust removal air intake port sucks the flying dust, most of the heat of the sintering mineral aggregate can be sucked away at the same time, so that the hot air quantity sucked by the high temperature air intake port is reduced, the temperature of the sucked hot air is lower, the high temperature heat taking effect of the waste heat boiler is seriously influenced, in order to solve the problems, a clapboard is mostly arranged in the smoke hood at present, get the wind gap and remove dust and get the wind gap and be located the both sides of baffle so prevent to remove dust and get the wind gap when removing dust and get the wind gap and get the hot-blast time production adverse effect of high temperature, produce the hindrance in order to prevent that the baffle from to the operation of sintering mineral aggregate, will make and leave the distance about 300mm between the below of baffle and the sintering mineral aggregate, consequently, can set up one in the below of baffle and fold paper and be used for the sealed between baffle and the sintering mineral aggregate, fold paper and be located sintering mineral aggregate top, the below and the sintering mineral aggregate that make the baffle can not direct contact.
The method for separating the high-temperature air intake and the dedusting air intake by adopting the partition plate at present at least has the following problems: because the temperature of the sintering mineral aggregate is higher, and the gap between the hinge and the upper part of the sintering mineral aggregate is extremely small, the sintering mineral aggregate can quickly break the hinge or abrade the hinge, so that the hinge is abraded and fails. At the moment, the partition plate loses the function of isolating the dedusting air intake port and the high-temperature air intake port, and simultaneously, because the negative pressure at the dedusting air intake port is far greater than the negative pressure at the high-temperature air intake port, a large amount of heat generated by sintering mineral aggregate is absorbed by the dedusting air intake port, so that the method cannot effectively solve the problem that the dedusting air intake port has adverse effect on the high-temperature air intake port; when the dust removal air intake absorbs the raised dust, the temperature of the sintered ore material at the material receiving point can be reduced due to the skimming of cold air, the sensible heat of the sintered ore material is reduced, and the effect of waste heat utilization is influenced; the loop wheel machine is constantly moving in the cold quick-witted working process of ring, and the position of petticoat pipe is immovable, consequently, there is the gap between trolley and the petticoat pipe, although the dust removal is got the wind gap and can be siphoned away the raise dust in the petticoat pipe, nevertheless when trying to weaken the negative pressure that the dust removal was got wind gap department and improving the hot wind temperature of getting of high temperature department of getting, the raise dust that receives the production of material point department can spill over through the gap between trolley and the petticoat pipe, and simultaneously, also there is the clearance between the horizontal segment of petticoat pipe and guide chute, the raise dust also can spill over through following this clearance, make operational environment worsen.
