The device that a kind of uncontrollable discharge dust pollution is administered
one, art
The utility model relates to the device of the administering method that fugitive dust pollutes in a kind of material processing procedure, belongs to the elimination of dust contamination method and apparatus produced in the process such as accumulation, transport, lifting, storage, handling of the industry bulk materials such as metallurgy, building materials, chemical industry and grain.
two, background technology
In recent years, the proposition of industrial PM2.5 problem causes the extraordinarily concern that people pollute airborne particulate, and industrial dust is one of main source of polluting of airborne particulate, very urgent to its improvement.Industrial dust is that the airborne dust produced by the production process of the industry such as metallurgy, machinery, building materials, light industry, thermal power generation brings, and it exists with the solid particle state of swimming in an atmosphere, all can work the mischief to human health and biology.Therefore, the emphasis that industrial airborne dust has become airborne particulate pollution control how is administered.
The source of industry airborne dust mainly contains two: the first discharges airborne dust in a organized way, and this type of airborne dust produces in material handling process primarily of all types of industries equipment; It two is uncontrollable discharge airborne dusts.This type of airborne dust mainly results from the operation process such as accumulation, transport, lifting, storage, handling of material.
Discharge airborne dust produces in material handling process primarily of all types of industries equipment in a organized way, produce the space that the position of airborne dust is normally airtight or relatively airtight, the discharge of airborne dust is generally discharged by the outlet that equipment is set, normally by dusty gas, cleaner is introduced by pipeline to the improvement of dust pollution, then by cleaner, gas solid separation is carried out to dusty gas, isolated dust is retracted, and the air after purification is emptying.The improvement emphasis of this type of dust pollution is the selection of cleaner, along with the progress of cleaner technology, every profession and trade has had the mature experience for various equipment elimination of dust contamination usually, and even defined classical resolution, their elimination of dust contamination is relatively easy.
Uncontrollable discharge airborne dust is that material produces in the process such as stacked, transport, lifting, storage, handling, produce the position normally open type operation of airborne dust, be difficult to close, randomness is strong, emission equivalent is poor, situation is complicated, and be always a difficult problem of administering in the industry, be the emphasis that people explore always.Last century Mo, the U.S., Japan are proposed flat bag deduster, achieve certain effect, but due to its deashing difficulty, the dust particularly regained easily forms secondary on adjacent filter bag surface and piles up, cleaning difficulty, for the dust extremely difficult cleaning especially that adhesiveness is stronger, seldom adopt at present.People turn to again the problem adopting the mode focused on to solve inorganization dust emission.What is called focuses on and arranges suspended hood at each airborne dust point exactly, then by pipeline, the dusty gas of multiple suspended hood sucking-off is introduced a deduster, concentrates purified treatment.This mode have received certain effect, but the problem brought is complicated pipeline makes fluid resistance be multiplied, thus causes system fan power consumption to be multiplied; Focusing on due to airborne dust simultaneously, the dust of withdrawal is away from dirt source, and this creates again the reprocessing problem of dust; Besides in order to form larger negative pressure in dust shield, control airborne dust to overflow in all kinds of gap, people can only strengthen suction air volume, this brings again the increase of the process ash-laden gas scale of construction, thus increase the investment of pollution control, also make system power consumption increase, operating cost raises, facts have proved, the effect done like this is unsatisfactory.Under this background, people develop single-machine dust remover again, so-called single-machine dust remover scheme, arrange a single-machine dust remover exactly at concrete airborne dust point, single-machine dust remover solves the fluid resistance rising because complicated pipeline causes to a certain extent, causes the problem that blower fan power consumption increases; The dust regained solves on the spot, also brings the convenience of system; But it can not reduce the process air quantity of Systematic control, and be still necessary due to dust shield to the pipeline of single-machine dust remover, fluid resistance still exists, and its power consumption is still higher; Restrict by factors such as device structures, equipment volume is still bigger than normal simultaneously, is difficult to adopt when site space is narrow and small.
In sum, to the resolution of uncontrollable discharge dust pollution, be all launch around the purification of dusty gas, what generally do not relate to dusty gas collects problem, many fugitive dust waste treatment projects are always unsatisfactory, and collecting of dusty gas is undesirable, often the key of problem.Facts have proved, fugitive dust features of pollution is different from dust pollution in a organized way, needs to solve two problems, collecting of first dusty gas for fugitive dust pollution control simultaneously; It two is cleaners.
