Abstract

The invention discloses a compact acid-base metering system with an emergency function, and an application method thereof. A conventional acid-base metering system is large in equipment consumption, large in occupied area and low in use efficiency, and safety problems are easily generated in the storage and use processes. The system comprises an acid storage tank (1), the bottom of the acid storage tank is respectively connected with an acid pipeline blow-off pneumatic valve (11), an acid liquor inlet pneumatic valve (13) of an acid-base temporary storage tank and an acid metering pump inlet pneumatic valve (12) through an acid storage tank acid outlet manual valve A (8) and an acid storage tank acid outlet manual valve B (9) in sequence, the acid liquor inlet pneumatic valve of the acid-base temporary storage tank is connected with an acid-base public tee joint (28) through a check valve (31), the acid-base public tee joint is respectively connected with an acid-base temporary storage box (3) and a check valve, and the bottom of the acid-base temporary storage box is connected with the acid-base public tee joint through an acid-base temporary storage box outlet manual valve (25) and an acid-base temporary storage box outlet pneumatic valve (29) in sequence. The compact acid-base metering system has the emergency function.

Description

technical field [0001] The invention relates to a compact acid-base metering system with emergency function and an application method. Background technique [0002] At present, ion exchange resins in the prior art are generally regenerated by acid and alkali, cation exchange resins can be regenerated by hydrochloric acid or sulfuric acid, and anion exchange resins are regenerated by sodium hydroxide. Correspondingly, acid-base metering systems need to be equipped, and conventional acid-base metering systems are equipped with 2 sets Acid storage tanks, 2 alkali storage tanks, 1 acid metering box and 1 alkali metering box, the capacity design of the conventional acid-base metering system is too large, the equipment consumption is large, the floor area is large, the use efficiency is not high, and the acid-base metering system belongs to Dangerous goods are prone to safety problems during storage and use. The fewer the number of equipment, the fewer the danger points, and the ...
