Description
Technical field
The present invention relates to a kind of open dust space dust soft seal dust control device of control and methods, can be used for medium-height grass
The material of the links such as medicine, tobacco leaf production manually loose station dust hinder control, it can also be used to Die Casting Workshop, foundry, welding
Workshop and spray painting polishing workshop etc. are unable to complete the dust link of fixing seal because of operational process of craft, can be empty in open dust
Between in soft seal control is formed to the dust of loss, and under air draught suction function, carry dust directed movement, both maintain to produce
It is normally carried out, and control dust recycling can be hindered, effectively will open dust area and operator separates, guarantee operating personnel from dust
Infringement.
Background technique
In recent years, dust emission standard in Chinese industrial place is continuously improved, some open process production link difference journeys
The discharge of the adjoint dust of degree, such as Chinese herbal medicine production, tobacco leaf production, dispersion casting, mineral processing, urgent need are effectively controlled
System.However in certain process procedures, due to technique or the pumping for needing not being available fixing seal mode and completing dust of operation
Row and control, become process industrial environmental Kuznets Curves urgent problem to be solved.
Currently, both at home and abroad to the improvement of open dust space dust mainly from the generation and ventilation depositing dust two for reducing dust
Aspect expansion, the main technical parameter by improving dust process of generation for reducing dust reduces the yield of dust, but does
Generating to zero dust has very big technical difficulty；And divulge information depositing dust be mainly using ventilation method, would be enclosed in workshop or
The mode of the dust ventilation of fixed area, which is transferred in clarifier, to be purified, and it is with higher closed that this requires dust regions
Property, the outside disperse of produced dust could be reduced, and frequent dust link is passed in and out for product, dust region is sealed to
Control the technical bottleneck of Dust Dispersion.Sealing does not reach requirement, can not be in time by dust region (especially personnel operating space)
Dust be discharged in time, it is weaker to the protective effect of operator.
Summary of the invention
The deficiency that the present invention is handled for the dust sealing and collecting that make up to open dust spatial dispersion, has invented one kind
The preferable soft seal dust control device of dust collection effect and method.
