Abstract

The invention discloses a cover plate glass pool furnace flue gas treatment system. The system has the function of removing both nitric oxide and sulfur simultaneously; a selective catalytic reductionsystem (SCR system) can reduce NO to N2 and water at a low temperature (300-400 DEG C), the requirement of flue gas temperature is reduced, so that after flue gas, which goes out of a glass kiln, dissipates heat in a pipeline and reaches the SCR system, the nitric oxide can still be fully removed; after subjected to nitric oxide removal, the flue gas is cooled by a cooling cycle tower and then enters an absorption cycle tower to be desulfurized, alkali liquor sprayed in the absorption cycle tower reacts with sulfide in the flue gas to remove the sulfide; by utilizing different temperature conditions of removing both the nitric oxide and the sulfide, one system completes the removal of the sulfur and the nitric oxide, and the system is simple in technological process and easy to realize.

Description

【Technical field】 [0001] The invention belongs to the field of cover glass flue gas treatment, in particular to a cover glass pool furnace flue gas treatment system. 【Background technique】 [0002] In the manufacture of cover glass, the flue gas is the main exhaust gas produced by the combustion of the pool furnace. The main components of the flue gas are nitrogen oxides and sulfides, both of which are pollutants that pollute the environment. Most of the flue gas treatment systems for cover glass in the prior art are selective non-catalytic reduction and denitrification technology (SNCR), which is carried out at high temperature and requires a high temperature at the flue gas outlet, above 1200°C, and the out-of-stock is not complete. The use cost is high; and the SNCR technology has no function of removing sulfide, so it is difficult to treat the sulfide in the exhaust gas. 【Content of invention】 [0003] The purpose of the present invention is to overcome the above-ment...
