Abstract

The invention provides a glass fiber kiln waste gas treatment device and method. The device comprises a kiln waste gas treatment device and a forming area waste gas treatment device, wherein the kilnwaste gas treatment device comprises a melting part chimney, a kiln waste gas pipeline and a waste gas induced draft fan; the forming area waste gas treatment device comprises a forming area chimney and a forming area waste gas pipeline which are communicated with each other; and the waste gas induced draft fan communicates with the kiln waste gas pipeline, and the forming area waste gas pipelineis connected into the kiln waste gas pipeline, so that the waste gas induced draft fan communicates with the kiln waste gas pipeline and forming area waste gas. According to the glass fiber kiln wastegas treatment method, the forming area waste gas treatment device is additionally arranged to treat the forming area waste gas, the forming area waste gas pipeline is connected into the kiln waste gas pipeline, the forming area waste gas pipeline and the kiln waste gas are treated in a unified mode, and meanwhile, the waste gas induced draft fan communicating with the kiln waste gas pipeline communicates with the forming area waste gas pipeline, so that the frequency of the waste gas induced draft fan is adjusted, the draft force of the melting part chimney and the draft force of the formingarea chimney are controlled, and the kiln pressure of the forming area is controlled within 0-5 Pa.

Description

technical field [0001] The patent of the present invention relates to a glass fiber kiln exhaust gas treatment device and method, and belongs to the technical field of glass fiber kiln high temperature flue gas treatment devices. Background technique [0002] Energy saving and emission reduction has become a global trend. The high-temperature flue gas from kilns carries a large amount of heat energy and discharges it into the atmosphere, resulting in a large amount of heat energy loss. The moisture content of the exhaust gas from the pure oxygen combustion fiberglass kiln reaches 53%, and the high-temperature flue gas reacts with the urea solution sprayed at the vertical flue at 850-1100°C to complete the denitrification. The subsequent exhaust gas treatment is mainly aimed at dust removal and desulfurization. From the perspective of the industry's current conventional equipment, the treated waste gas is far below the national emission requirements. However, for the E-glass...
