酸碱洗涤设备分上中下三段，中下二段为碱洗段，上段为水洗段。中段为浓碱液

The acid-alkali washing equipment is divided into three sections: the upper, middle and lower sections. The middle and lower sections are the alkali washing section, and the upper section is the water washing section. The middle section is concentrated alkali liquid, and the lower section alkali liquid is dilute alkali liquid flowing down from the middle section, which is circulated by the dilute alkali circulation pump. New alkali liquid is continuously fed into the middle section with an alkali liquid supply pump.

The acid alkali washing equipment is divided into three sections: upper, middle, and lower. The middle and lower two sections are the alkali washing section, and the upper section is the water washing section. The middle section contains concentrated alkali solution, while the lower section contains dilute alkali solution flowing down the middle section, which is circulated by a dilute alkali circulation pump. New alkali solution is continuously fed into the middle section using an alkali supply pump.

The acid-base washing equipment is divided into three sections: the upper, middle and lower sections, the middle and lower sections are alkali washing sections, and the upper section is water washing sections. The middle section is concentrated alkali liquor, and the lower section is dilute alkali liquor flowing from the middle section, which is circulated by the dilute alkali circulation pump, and the new alkali liquor is continuously sent to the middle section by the alkali liquor supply pump.
