碘络合法净化含汞烟气

我国研制的用于处理锌精矿焙烧脱硫的含汞烟气的碘络合法,是将含汞和二氧化硫的烟气经吸收塔底部进入填满瓷环的吸收塔内。并由塔顶喷淋含碘盐的吸收液来吸收汞。

循环吸收汞的富液,定量地分批引出进行电解脱汞,产出金属汞。

用碘络合法来处理含汞和二氧化硫的烟气,除汞率达99.5%,尾气含汞小于0.05mg∕m3,烟气除汞后制得的硫酸含汞小于百万分之一。回收1t汞消耗碘盐200kg,耗电56000kW·h。

用碘络合法处理同时含有汞和二氧化硫的烟气,与氯化汞法比,不存存氯化汞毒害的二次污染,流程短,且适于高浓度二氧化硫烟气的脱汞。

Waste Yarn Spooler

Waste yarn spooler is a device used in knitting machines to hold and dispense waste yarn. Waste yarn is used to create a temporary cast-on or to hold stitches in place while knitting. The spooler holds the waste yarn and allows it to be easily fed into the knitting machine. It also keeps the waste yarn organized and prevents it from getting tangled or knotted. The waste yarn spooler can be attached to the knitting machine or used as a standalone device.
