Technical Field
The utility model belongs to the technical field of sulfuric acid preparation equipment, and particularly relates to a purification water-saving system for acid preparation.
Background
In the sulfuric acid purification process, circulating pump is adopted for circularly washing the flue gas by each process washing device, liquid is conveyed and transferred by the conveying pump, and cooling water is supplied to cool and protect the pump during the use of the circulating pump and the conveying pump; meanwhile, in the purification process, in order to prevent the equipment from being damaged due to the fact that negative pressure inside each process washing tower and the electric demister is too large, a safe water seal tank is often adopted for water seal protection, and in order to guarantee the water seal effect, water needs to be constantly supplemented to guarantee the water level of the water seal tank.
However, the use of cooling water for the transfer pump and the circulating pump and the addition of water for the safety water seal consumes a large amount of production water, and the discharged pump cooling water and water seal overflow water are sent to a waste acid treatment process for treatment operation, so that the discharge of waste acid is increased, and the subsequent waste acid treatment cost is too high.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides the acid-making purification water-saving system which saves water, reduces the external discharge of waste acid and reduces the treatment cost of the waste acid.
In order to achieve the purpose, the utility model adopts the following technical scheme: an acid making purification water-saving system comprises a circulating pump, a delivery pump, a cooling pipeline, a purification safety water seal tank and a water collecting tank, wherein the circulating pump is used for washing flue gas in purification system process equipment; the water collecting tank is connected with the purification system process equipment through a reuse water pipe, and a reuse water pump is installed on the reuse water pipe.
Preferably, the purification system process equipment comprises a primary dynamic wave scrubber, a gas cooling tower and a secondary dynamic wave scrubber.
Preferably, the purification safety water seal groove is connected with a water seal water replenishing pipeline for water seal water replenishing.
Preferably, the purification system process equipment is connected with a process water replenishing pipeline for replenishing process water and a liquid discharge pipeline for discharging waste acid.
The utility model has the technical effects that: the cooling water of the circulating pump and the delivery pump and the concentrated collection and reuse of the overflow water of the purified safe water seal tank effectively improve the utilization rate of the equipment cooling water in the sulfuric acid purification process, reduce the total water consumption of the purification process, effectively reduce the waste acid discharge capacity of the purification process and ensure the treatment cost of the waste acid.
