The equipment manufacture development that border monitoring is attached most importance to, a collection of Novel environment-friendlymaterial material of researching and developing and demonstrate, medicament and environmentally friendly product.
Promote it is inter-trade, utilize association's construction across Enterprises.Environmental protection facility operation qualification licensing system is carried out, promotes flue gas desulfurization
The specialization of the pollution Facilities Constructions such as denitration, town sewage garbage disposal, hazardous waste processing disposal and operation, socialization, city
Fieldization process, carries out flue gas desulfurization facilities franchise operation.
In the case where country advocates energy conservation and environmental protection, the major premise of stringent control pollutant emission, flat glass industry has itself
Special character.Selected raw material must be used by producing high-quality glass, therefore plate glass enterprise is difficult to use ecological Industrial Area
Pattern carrys out Implementing Circular Economy.Flat Glass in China industrial development circular economy should be advanced in glass production link, use
Energy saving, water-saving technology, reduces consumption, reduces pollutant emission using advanced green technology, walks energy saving and environment friendly development.
Most of floatation glass production line in China is using heavy oil as fuel, the SO in flue gas2And discharged nitrous oxides become
Cause the principal element of atmosphere pollution.Float glass factory environmental protection standard is to glass works's discharged nitrous oxides and SO2Row
It has been placed with clear and definite restriction.Therefore, new and effective denitration desulphurization energy-saving environment protection technology is developed, is China's glass industry
One of following important tackling key problem field.
To implement circular economy and the policy of energy-saving and environment-friendly theory and clean manufacturing, this patent for China 500t/d and
Float glass furnace above, develops the intelligent oxygen-enriched combusting of float glass furnace and desulfurization and denitrification integral technology.
In conclusion float glass furnace nitrogen oxides and SO2Discharge it is more, the float glass desulfurization to have put into operation at present
Denitration Practical Project is less, although having a more mature desulfurization and denitration technology in industries such as electric power, cement, but glass furnace
Actual operating mode have larger difference therewith.
