Hydrolysate waste acid neutralization facility

Abstract

The invention relates to a hydrolyzate waste acid neutralization facility, and belongs to the field of processing facilities. Rectangular vertical plates are vertically arranged at the two ends of the upper surface of a base in the longitudinal direction respectively, an oval third-stage stirring tank is transversely installed on the two vertical plates, a spiral third-stage stirring shaft is installed in the third-stage stirring tank, and a third-stage stirring shaft is installed in the third-stage stirring tank; an elliptical second-stage stirring tank is mounted on the third-stage stirring tank, a spiral second-stage stirring shaft is mounted in the second-stage stirring tank, a cylindrical first-stage stirring tank is mounted on the second-stage stirring tank, a spiral first-stage stirring shaft is mounted in the first-stage stirring tank, and a cylindrical second-stage stirring shaft is mounted in the second-stage stirring tank; after entering the first-stage stirring tank, lime powder and waste acid are rotationally stirred by the first-stage stirring shaft and then pushed into the second-stage stirring tank, the second-stage stirring shaft is rotationally stirred and dried and then pushed into the third-stage stirring tank, and the third-stage stirring shaft is rotationally stirred and dried and then pushed into the discharge port to flow into the turnover box.

Description

technical field [0001] The invention relates to a hydrolyzate waste acid neutralization facility, which belongs to the field of processing facilities, in particular to a facility for neutralizing hydrolyzate waste acid by adding lime and stirring in multiple stages. Background technique [0002] Hydrolyzed waste acid, turmeric mud is added with hydrochloric acid to stir, and the waste discharged after cooking. Existing enterprises that process hydrolyzate need to carry out the steps of cleaning, crushing, adding hydrochloric acid to stir, cooking, deslagging, deacidification, drying, and waste acid treatment when processing turmeric, and finally can produce hydrolyzate. At present, most enterprises use the neutralization tank to stir and neutralize the hydrolyzate waste acid. This method is simple and effective. However, after adding lime powder and hydrolyzate waste acid to the neutralization tank, it needs to be shoveled Enter the drying room to dry the lime powder before...

Problems solved by technology

At present, most enterprises use the neutralization tank to stir and neutralize the hydrolyzate waste acid. This method is simple and effective. However, after adding lime powder and hydrolyzate waste acid to the neutralization tank, it needs to be shoveled Dry the lime powder in the drying room before it can be used again, which is time-consuming and inefficient
