The printing profession volatile organic compound waste gas government
engineering research volatile organic compound (VOC) is kind of
gaseous state pollutant, the massive industries organic waste gas
disperses into the atmosphere, inevitably causes the atmospheric
environment drop in quality, brings the serious harm for the human
body health, the national economy creates the heavy loss for.
Especially is difficult regarding the low density VOC waste gas
control. In the plastic color printing profession, each kind of
diluent massive uses, produce the industry organic waste gas, creates
to the environment pollution, is question which the current printing
profession environmental protection urgently awaits to be solved. This
article take the Dalian greatly rich plastic color printing limited
company as the research background, the organic waste gas which
produces in the production process carried on the monitor to it,
finally indicated, the organic waste gas principal constituent is the
toluene and the ethyl acetate, the toluene discharges the density and
discharges the speed to have exceeds the allowed figure, has already
caused the certain degree pollution to the environment, therefore, is
urgent needs to carry on the government. The VOC control may from the
many kinds of ways realization, the most economical method be reduces
VOC through the clean production way the use and sends out. But
cleanly produces the road very is also long, the terminal government
technology still was the essential one method. This article introduced
in the project actual center application each kind of organic waste
gas government technology, and carried on the comparison to various
technologies, the synthesis had considered the consumption of
material, the energy consumption, the investment, the processing cost
and so on, in this foundation, the choice activated charcoal textile
fiber adsorption - condensation recycling craft did for this project
organic waste gas processing method. And has completed the government
plan technological design, has carried on the investment and the cost
analysis, uses this method to be able effectively to govern the VOC
waste gas, simultaneously satisfies in the economical the request.
