Abstract
The utility model relates to the technical field of the mechanical dust removing device, in particular to a dust remover for treating metallurgy hot-rolling and finish-rolling dust by dry method, comprising a sucking cover, an air inlet pipe, a waterproof greaseproof filter element type dust collector, an air outlet pipe, a draught fan, an exhaust duct and a dust exhaust apparatus. Compared with prior art, the utility model initiates the precedent of treating metallurgy hot-rolling and finish-rolling dust by the dry method, the operation is easy, the maintenance is convenient, the durability is long, the resistance of the system operation is stable, the efficiency is high, the catch dust can be reused, and the secondary pollution is avoided.
Description
[technical field]
The utility model relates to dust removal with machine device technique field, specifically a kind of dust arrester that adopts the metallurgical hot fine rolling dust of dry treatment.
[background technology]
In the metallurgical hot rolled plate production process, material difference, thickness difference, the width difference of milling train institute rolled plate, the Dust Capacity of its production also can be different.Because steel billet is through the high temperature heating, in order to protect the life-span that prolongs the milling train topping roll, regulation must be sprayed cooling water and lubricating oil to roll in the rolling mill practice.Before finishing mill, will produce the air mass that a large amount of iron oxide dusts, steam, oil smoke etc. are formed like this, thus contaminated environment and influence plate surface quality.
Solved the hot-rolling mill dedusting in the past and all be both at home and abroad and adopted wet-scrubbing equipment, it be a kind of need be with the cleaner of big water gaging when capturing dust or in body, remove dust.As disintegrating scrubber, wet electrical dust precipitator.The former dust catching rate is very low, does not reach national environmental standard, and the latter is because its technical complexity, domestic can't production, and cost an arm and a leg.These two kinds of dedusters are owing to adopt wet dust removal, and the dust of its capture finally is the mud shape, causes secondary pollution, also need pass through water treatment, and this also will spend high expense.
[summary of the invention]
The purpose of this utility model is under the prerequisite that guarantees cleaner efficient operation steady in a long-term; can adopt dry method to capture the equipment of the iron oxide fine dust that contains a large amount of steam, oil smoke that produces in the hot-rolled steel production; the protection plate surface quality reduces environmental pollution.
For achieving the above object, design a kind of dust arrester that adopts the metallurgical hot fine rolling dust of dry treatment, by inhaling cover, blast pipe, the filer element type dust-precipitator of Waterproofing/oilproofing, discharge pipe, blower fan, exhaust duct, dust exhaust is formed, it is characterized in that: suction is covered with blast pipe, the blast pipe other end connects the filer element type dust-precipitator air inlet of Waterproofing/oilproofing, the filer element type dust-precipitator bottom of Waterproofing/oilproofing is provided with dust exhaust, the filer element type dust-precipitator left end of Waterproofing/oilproofing is provided with air outlet, air outlet connects discharge pipe one end, the other end of discharge pipe connects air inlet, the blower fan other end connects exhaust duct, dust sucks by inhaling cover, blast pipe enters the filer element type dust-precipitator of Waterproofing/oilproofing, dust is captured by filter core in the filer element type dust-precipitator of Waterproofing/oilproofing, and separated from the gas, clean gas is discharged by blower fan and exhaust duct, and dust is discharged by dust exhaust.The material for core of the filer element type dust-precipitator of Waterproofing/oilproofing is made up of metal or sintered plate or ceramic material.
The utility model is compared with prior art, has initiated the precedent with dry treatment metallurgy industry hot fine rolling dust, and simple to operate, be convenient to safeguard, long service life, system's running resistance is stable, and the dust that the efficient height traps can utilize again, avoid secondary pollution, be worthy to be popularized.

[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further described, the utility model is still more clearly concerning those skilled in the art.
The dust that contains steam, oil smoke that example 1. produces in inhaling the enough negative pressure suction operations of rolling of cover place generation by blower fan, dust is sent in the filer element type dust-precipitator of Waterproofing/oilproofing through blast pipe, dust is also separated from the gas by filter core capture wherein, filters the back clean gas and is discharged by blower fan and exhaust duct.Dust of being gathered by filter core in the filer element type dust-precipitator of Waterproofing/oilproofing and filter core break away from, and the dust exhaust bottom the filer element type dust-precipitator of Waterproofing/oilproofing is discharged, and is encased in the dust bag.
Claims (2)
1. dust arrester that adopts the metallurgical hot fine rolling dust of dry treatment, by inhaling cover, blast pipe, the filer element type dust-precipitator of Waterproofing/oilproofing, discharge pipe, blower fan, exhaust duct, dust exhaust is formed, it is characterized in that: suction is covered with blast pipe, the blast pipe other end connects on the filer element type dust-precipitator air inlet of Waterproofing/oilproofing, the filer element type dust-precipitator bottom of Waterproofing/oilproofing is provided with dust exhaust, the filer element type dust-precipitator left end of Waterproofing/oilproofing is provided with air outlet, air outlet connects discharge pipe one end, the other end of discharge pipe connects air inlet, the blower fan other end connects exhaust duct, dust sucks by inhaling cover, blast pipe enters the filer element type dust-precipitator of Waterproofing/oilproofing, and dust is captured by filter core in the filer element type dust-precipitator of Waterproofing/oilproofing, and separated from the gas, clean gas is discharged by blower fan and exhaust duct, and dust is discharged by dust exhaust.
2. a kind of dust arrester that adopts the metallurgical hot fine rolling dust of dry treatment as claimed in claim 1 is characterized in that; Material for core in the filer element type dust-precipitator of Waterproofing/oilproofing is made up of metal or sintered plate or ceramic material.
