Background technique
Microenvironment refers to public transport environment inside car, environment in subway, hires out environment inside car, domestic environment and all public fields
The environment of conjunction." microenvironment " contacted at any time in our daily lifes, for example, just renovated new family, father secondhand smoke, new
Love vehicle started with etc..These microenvironments are easy to produce the pollutants such as dust, formaldehyde, ozone, and harmfulness is no less than overall situation
The pollutants such as haze.
Simultaneously in some other microenvironments, there are the pernicious gases such as nitrogen oxides, sulfur dioxide, how quickly to go
It removes.
Common adsorbent has to be adsorbed by the various acticarbons and metal of raw material, nonmetal oxide class of carbonaceous
Agent (such as silica gel, aluminium oxide, molecular sieve, natural clay).Most representative adsorbent is active carbon, and absorption property is suitable
It is good, but cost is relatively high, Zeng Yingyong is used to the toluene in adsorbed water body in the event of Song Hua River.Secondly there are also molecular sieves, silicon
Glue, activated aluminum, polymer absorbant and biological adsorption agent etc..
Adsorbent is typically all to use in the industrial production, therefore adsorbent can be divided into six greatly according to the common property of industry
Class: silica gel, it is mainly used for dry, admixture of gas and separation of petroleum component etc.；Aluminium oxide, it is also a kind of suction of dehydration
Attached dose；Active carbon is mainly used for water process, decoloration and gas treatment；Polyacrylamide is mainly used for sanitary sewage and organic waste
Water；Zeolite molecular sieve, it is dry for gas absorption separation, gas and liquid；Carbon molecular sieve, main rise transports channeling, micro-
The effect of Kong Zeqi molecular sieve.
Adsorbent is generally also classified into two class of organic matter and inorganic matter, organic species such as wheat-germ meal, the maize powder of degreasing,
Corncob fragment, bran, soybean fine powder and bibulous cereals etc..Inorganic species then include silica, vermiculite,
Calcium silicates etc..
Summary of the invention
In view of this, can quickly have the present invention provides a kind of method using high-efficiency adsorbent processing pernicious gas
The processing pernicious gas of effect, treatment effeciency is high and realizes the qualified discharge of exhaust gas.
The technical solution adopted by the present invention to solve the technical problems is:
A method of pernicious gas being handled using high-efficiency adsorbent, it is 75-85 DEG C that pernicious gas, which is warming up to temperature, so
After compressed, be compressed to the 1/3-1/2 that volume is initial volume, then by high-efficiency adsorbent it is broken after cross 200-250 mesh,
Then broken absorbent powder is blown into compressed pernicious gas with compressed air, is then in temperature
75-85 DEG C, pressure is under 2-3 atmospheric pressure, and additional ultrasound reacts 0.5-1 hours, then releases gas, adopt simultaneously
With dust collecting system by absorbent powder.
The absorbent powder quality that every cubic metre of original pernicious gas is added is 1-2kg.
The power of the ultrasound is 2-4kw.
The dust collecting system uses bagroom, and the mesh number of cloth bag is 1000-1200 mesh.
The pernicious gas is the gas containing formaldehyde, ozone, nitrogen oxides and sulfur dioxide, formaldehyde, ozone, nitrogen oxidation
Object and content of sulfur dioxide are lower than 200ppm.
The present invention is blown into absorbent powder by the way that pernicious gas heats up and in the case where gas compression, can be very big
The contact area of expansion adsorbent and pernicious gas adsorption efficiency can be improved while by the setting of pressure and temperature.
The invention has the following beneficial effects: pernicious gas can be handled quickly and effectively, treatment effeciency is high and realizes exhaust gas
Qualified discharge.
