AI Technical Summary

Problems solved by technology

Large area, complex operation, large structure layout, complex on-site installation, and easy blockage during system operation
It cannot remove a large amount of pollutants, whether it is gas or dust, which greatly increases the load of the packed alkali washing tower, and the packing is relatively easy to block, resulting in high operating costs

Abstract

The invention relates to an optical fiber preform rod sintering waste gas treatment system and a treatment method thereof. The treatment system comprises a venturi washing tower (1), a filler washingtower (2), a circulating tank (3), a fan (4), an air pipe (5) and a chimney (6), wherein the venturi washing tower (1) and the filler washing tower (2) are vertically fixed on the circulating tank (3)respectively, the air pipe (5) is communicated with the top of the venturi washing tower (1), the air inlet end of the fan (4) is communicated with the top of the filler washing tower (2), the air outlet end of the fan (4) is communicated with the chimney (6), spraying liquid is sprayed in the venturi washing tower (1), and an alkali solution circulates in the filler washing tower (2). The optical fiber preform rod sintering waste gas treatment system is high in absorption efficiency, and two-stage absorption of the venturi washing tower and the filler washing tower is adopted, so that tail gas emission is ensured to be lower than the strictest national emission standard.

Description

technical field [0001] The application belongs to the field of optical fiber production and manufacturing, and in particular relates to an optical fiber preform sintering exhaust gas treatment system and a treatment method thereof. Background technique [0002] The optical fiber preform industry has always mainly adopted the process mode of "chlorine spraying alkali spray / dynamic wave scrubber + absorption tower" for the treatment of waste gas after sintering, but in the actual operation process, there are many problems, such as large floor space, absorption Low efficiency, easy to block, not conducive to safety and personnel health and other shortcomings. Under normal circumstances, the pollutant in the gas is chlorine gas, and the chlorine-containing waste gas and air from sintering, gas cabinets, etc. are collected through the air duct and discharged to the sintering waste gas treatment system. The exhaust gas flows from top to bottom in the power wave reverse spray sect...
