Abstract
The utility model relates to a production device for preparing a high-purity sulfuric acid solvent for para-aramid spinning. The production device is characterized in that a filter, a conveying pump and a flowmeter are respectively connected between the outlet end of a concentrated sulfuric acid storage tank, the outlet of a fuming sulfuric acid storage tank and the inlet end of a mixture; and a concentration on-line measurer is connected between the outlet end of the mixture and the inlet end of a high-purity sulfuric acid storage tank. The device is used for preparing the high-purity sulfuric acid solvent by adopting two conventional sulfuric acid products, so that the high-purity sulfuric acid solvent can be prepared by a para-aramid production enterprise; and the dependency on a sulfuric acid production factory is eliminated. Compared with the high-purity sulfuric acid solvent purchased from the sulfuric acid production factory, the high-purity sulfuric acid solvent is relatively low in cost and is relatively flexible during self preparation of the para-aramid production enterprise.
