Air pollution control process and apparatus for glass furnace

摘要

An air pollution control process and apparatus for glass furnaces for use in the furnace's waste gas outlet including passing the waste gases through a spray type neutralization tower to remove sulphates in the waste gases by spraying an absorbent (NaOH) to reduce the opacity of exhaust gas, and employing a pneumatic powder feeding device to feed flyash or calcium hydroxide periodically in a path between the spray type neutralization tower and a bag house to maintain normal functioning of the filter bag in the bag house.
