Description
Technical field
The present invention relates to the collection devices and method of acid mist in environment protection field more particularly to stationary source atmosphere.
Background technique
Mist is the tiny droplet swum in low latitude, is suspended in subaerial aerosol.The general journey ball-type of droplet, diameter
Between 2-100 μm.Acid mist is one kind of broad sense acid rain, refers to misty acid.Forming feature: 1. due to acid solution table
The evaporation in face, acid molecule enter air, absorb moisture and agglomerate and be shaped to acid mist drop；2. having chemical reaction and life in acid solution
At bubble, explosion after bubble emersion liquid level takes drop into air out of.Occur mainly with chemical industry, metallurgy, light industry, plating, spinning
Knit the industries such as (chemical fibre), grease, papermaking and machine-building in sour process.
Acid mist is formed since the acidic materials in atmosphere are absorbed by droplet, and acid drop is also to form the important field of acid mist
Institute.With the rapid development of economy, the consumption of fossil energy rapidly increases, the occurrence frequency of acid mist is higher, the pH value of acid mist
Can be down to 2.0 hereinafter, greasy weather, the exhaust gas accumulated in low latitude are not easy to dissipate, acid mist destroys Plant Cuticular wax layer, inhibits Plant Light
Its growth is hindered with effect, leads to Plant death, Forest dicline；People's Long Term Contact acid mist has Atrophic nasal mucosas and with smelling
Feel decline or disappear, chronic bronchitis, pulmonary edema and dental erosion, acid mist contain there are many carcinogenic factor of causing a disease, and induce
A variety of diseases and cancer, damage to plant are difficult to estimate to the extent of damage of body health.
Since mist only occurs in limited when and where, collect, acquisition difficulty, collecting fog is typically all related personnel
The easy device of qualification in practical study has no the molding fog collector of exploitation.Current fog collection method is divided into two
Class, one is many filament grids of longitudinal pull-up, rear sets up fan and attracts air, and droplet is made to hit collection on filament；Separately
One is swingle collecting method, swingle top has trap, and motor drives swingle rotation, and droplet passes through centrifugal action,
Collect collection.
The processing method bulk fluid absorption process of acid mist, suspends and moulds ball cladding process or generated with fog inhibitor at electrostatic demisting method
Foam method.
The detection method of acid mist, mainly there is a spectrum detection method and chromatographic detection, spectrum detection method include ultraviolet light detection,
Chemical light detection, fluorimeter detection, IR, Raman etc.；Chromatography detection includes gas phase, liquid phase.
Acid mist collecting, one is droplets to be directly collected into collector, and one is lye is packed into collector for exception
It collects.Collection method droplet as described in 1 hits collection either swingle collecting method on filament.We have found that collecting
There is no a specific separation systems during droplet, and if the concentration of acid mist is very big, filament is not durable inevitably, and
And there are other impurities in the solution collected.And if it is using lye absorbing liquid to collect, then easily freeze in winter.
