　　Principle of technology of equipment of chemical plant off-gas treatment:

　　 Washer

Washer is tower of filling of cleanse of vertical gush drip washing commonly, in-house shower nozzle and filling layer distributing alternately. Filling has the larger area that compare a list, use at increasing the interface between two kinds of fluids to accumulate. Waste gas is entered by bottom, classics filling layer and demist implement hind, by coping eduction. The liquid is sent sprinkler head by water pump ejective, descend downward, classics filling layer returns cistern. The foreign matter conglutinate in waste gas is on filling, water tank is entered below current action after, achieve hold back a purpose. The impurity in cistern needs to clear regularly, sewage needs to be discharged regularly.

The goal that establishs washer here basically is purify Qi Wu and drop air temperature.

　 Principle of microtherm plasma technology

Microtherm plasma is the material after afterwards solid state, liquid state, gaseous state the 4th condition. By electron, ionic, freedom radical and neuter particle composition. Microtherm plasma organic gas purifier is to use plasma. The rate that reachs 8 million times 50 million times with every second relapses element of gas of bombard peculiar smell, go all sorts of composition in waste gas of activation, ionization, splitting decomposition, produce a series of mixed chemical response such as oxidation thereby, repass multistage is purified, translate into of ill other people clean air is released to nature. Its job principle is as follows:

(1) use high-pressured electric field to decompose ionization of waste gas element, form microtherm plasma. High-energy electron also can by haloid wait for the corporeal capture with electronic stronger affinity with oxygen, become anion

(2) high-pressured electric field is met the oxygen in ionization air, the made oxygen that produces free form, namely active oxygen, because oxygen place carries free to losing an electron lopsided need to be united in wedlock with oxygen element so, produce ozone then.

(3) ozone oxidizes the effluvial gas element that break into pieces to wait for mineral into CO2 and H2O, achieve processing goal thereby.

　　 UV light is solved

It is current that UV light solves oxidation industry is effluvial one of advanced technologies in off-gas treatment technology, “UV light solves oxidation module ” design and development are mature the uncertainty of property of effluvial waste gas mixes industry complexity, the design from the project, form a complete set, installation, debug, safeguard waited for a respect to provide huge feasibility, dependability, flexibility. Its job principle is as follows:

(1) use specific wave band (253.7nm) ultraviolet ray undertakes destructive to the molecular catenary of effluvial gas, its macromolecule structure is broken into pieces turn young member into the structure. The macromolecule polymer such as polyethylene, polypropylene can be decomposed young member.

(2) use specific wave band (185nm) the oxygen that ultraviolet ray makes the oxygen element in air produces free form, namely active oxygen, because oxygen place carries free to losing an electron lopsided need to be united in wedlock with oxygen element so, produce ozone then.

(3) in activator (TiO2) below action, the oxidation of effluvial gas element that ozone will break into pieces becomes the mineral such as CO2 and H20, achieve processing goal thereby.

　　 Activated carbon

Activated carbon is a kind of porous material that contain carbon, it has the hole construction that develops highly, the poriferous structure of activated carbon offerred many surface to accumulate for its, can with gas (foreign matter) sufficient contact, gifted thereby the adsorptive function with activated carbon peculiar place, make its are achieved very easily absorb the purpose that collects foreign matter. Resemble magnetic force mutual gravitational force is had between all elements euqally. because such, the many element on activated carbon hole wall can produce powerful gravitational force, achieve the goal in attracting harmful impurity bore diameter thereby.

Not all activated carbon can be sucked add harmful gas, be more than the diameter of harmful gas element slightly when the hole structure of activated carbon only, below the condition that can make harmful gas element complete enter (too big or too small be no good) ability achieves very good adsorptive result. Need retexture after adsorptive carrier is saturated.

　　 Chemical waste gas (tail gas) processing equipment suitable scope:

Factory of factory of factory of not saturated colophony, synthetic resin factory, company of pharmaceutical factory, biology, paint, plastic second birth, circuit board factory, petro-chemical factory, presswork plant of factory, gasworks, fertilizer, cast mill of factory, refinery, feed, steely factory, synthetic detergent factory, plant of paper mill, fertilizer waits the chemical deodorization of gas of poisonous and harmful contaminant a moment to purify processing.
