Application of brine to boiler softened water in stead of industrial salts

Abstract

Application of brine to boiler softened water in stead of industrial salts comprises sodium hydroxide, a brine storage tank A, a precision filter, a brine storage tank B, an electromagnetic valve, a delivery pump and an ion exchanger. The sodium hydroxide is connected to the brine storage tank A which is connected to the precision filter; the precision filter is connected to the brine storage tank B; the brine storage tank B is downwards connected to the electromagnetic valve; the electromagnetic valve is downwards connected to the delivery pump; and the delivery pump is downwards connected to the ion exchanger. The ion exchanger sends out a control signal which is connected to the delivery pump and the electromagnetic valve simultaneously. According to the invention, brine is taken as a regenerant in stead of the industrial salts and used as the regenerant for the ion exchanger; and as brine can cause influence on resins in use since containing few ions of calcium, magnesium and iron, the sodium hydroxide is firstly added to the brine storage tank to adjust the PH value to about 9 before use. The application of the brine is simple in integrated process, convenient for operation and use, good in stability and high in reliability; and the fault rate of equipment is greatly reduced.

Description

technical field [0001] The invention relates to boiler water softening technology, in particular to the application of brine instead of industrial salt on boiler softened water. Background technique [0002] In the production of softened water outside the industrial boiler pot, sodium ion exchangers are commonly used softened water maturation equipment, and industrial salt has been used as the resin regeneration agent during its operation. The use of industrial salt has the following disadvantages: the use cost of industrial salt is relatively high; industrial salt has to be added manually, and the labor intensity of workers is relatively high; due to the characteristics of the production process, industrial salt often contains insoluble substances such as sediment, which will cause serious damage during application. The system is blocked, which affects the dissolution rate of industrial salt and the concentration of the salt solution used for regeneration, resulting in poor...

Problems solved by technology

The use of industrial salt has the following disadvantages: the use cost of industrial salt is relatively high; industrial salt has to be added manually, and the labor intensity of workers is relatively high; due to the characteristics of the production process, industrial salt often contains insoluble substances such as sediment, which will cause serious damage during application. The system is blocked, which affects the dissolution rate of industrial salt and the concentration of the salt solution used for regeneration, resulting in poor regeneration of the resin, resulting in unqualified final softened water; the cleaning of the sediment must be stopped, affecting normal production, and there will be A large amount of industrial salt and salt liquid are wasted, resulting in a low utilization rate of industrial salt; the sediment in industrial salt will cause damage to the rotary valve and other equipment in the system, affecting the normal operation of the equipment
