Description
Technical field
The utility model belongs to technical field of industrial dust removal, and in particular to a kind of purifier of workshop dedusting.
Background technology
In certain workshops, especially grind, polish etc. techniques workshop, will produce a large amount of powder in process of production
Dirt not only seriously pollutes environment, but also endangers the health of staff.For in industrial plant, dust content is excessively high
Serious security risk can be brought, open fire is met such as the dust of combustibles and causes blast accident.According to the capture method of solid particle
It divides, generally includes following several dust removal methods：Dust removal with machine relies primarily on mechanical force such as gravity, inertia force, centrifugal force etc. and goes
Except grit, efficiency of dust collection is low；Electric precipitation realizes that grit detaches using high-voltage dc accelerated sedimentation, high dust collection efficiency, but sets
Standby complexity, investment are higher；Grit in gas is trapped in strainer by dust removal by filtration, although efficiency is higher, strainer service life
Low, use cost is high.
Currently, in workshop dedusting frequently with cyclone dust collectors, sack cleaner etc..Cyclone dust collectors because rotation generate from
Mental and physical efforts are smaller, realize that the separative efficiency of dust and air is not high by centrifugation force effect；Sack cleaner is then to utilize special filter
Dust in dust laden air is retained down by cloth, but following problem is that filter layer blocks caused by dust, causes to hinder
Power increases, while the dust on filtrate is also possible to be blown afloat again and reenter in air, reduces efficiency of dust collection.It is this kind of common
Wind turbine and motor of dust removal machine etc. are often containing heavy air side, so after running a period of time, due in air containing heavy
Amount increases and motor temperature increases, and motor is caused to hold very much sparking, and dust chance open fire, which easy tos produce, to be fired, and this kind of accident is shown in repeatly
It is not fresh.Currently, most of dust workshop is all that spray scrubber, such spray scrubber is used often to use plate column, plate
The treatment effeciency of formula tower is less than packed absorber, therefore relatively low for the efficiency of this kind of chalk dust removing machine for large-scale dust workshop.
CN201510356500.3《A kind of air cleaning facility for removing workshop dust》Using single-stage absorption tower, which is needle
Shop worker is proposed, is mainly used for providing pure air to worker in dust workshop, is not used to the dedusting in entire workshop
Work.So research and development new workshop dust removal machine and dust removal method have industrial expansion important research significance.

0.05% neopelex.After completion processing, 2.5 a concentration of 30 μ g/m of outlet air PM after testing3, PM 10 it is dense
Degree is 90 μ g/m3.But after a period of use, the pollution of glycerine water solution is very heavy, is easy to block water pump.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
