What Are the Different Water Softener Parts?

Water softening equipment, as the name implies, is a device that reduces water hardness. It mainly removes calcium and magnesium ions in water. When the water is deep well water or the hardness of the water source is very large, the use of water softening equipment is to remove calcium and magnesium in water. Ion content reduces calcium and magnesium ions in water. In the process of softening water, the softened water equipment cannot reduce the total salt content in the water. It is widely used in hot water boiler systems, heat exchange systems, industrial cooling systems, central air conditioning systems, and other water equipment systems.

Working process of water softener

Selection of location of soft water equipment: The water softener must be placed on a firm horizontal ground. The distance from the drainage ditch is better. The distance from the heat source such as the boiler must be more than 3 meters. It is strictly prohibited to approach acidic liquids or gases. If you need to add other water treatment equipment (

1. First you need to provide what kind of system you need to use demineralized water:

1) Heating 2) Cooling water supply 3) Process water 4) Steam boiler 5) Iron and steel smelting industry 6) Chemical and pharmaceutical industry.

System water use time:

I.e. running time / hour water consumption / average value / peak value /

Does the equipment require continuous water supply? If necessary, choose two-piece centralized control or double-control double-bed series, otherwise select single-valve single-tank series.

Total source water hardness

The water source is municipal tap water \ groundwater \ surface water source, and the total hardness of the raw water in the use area. For a certain model

Boiler demineralized water equipment is a raw water pretreatment device for boiler fouling, which removes calcium and magnesium ions in raw water and the elements that cause boiler fouling. Reasons for the soft water hardness of boiler softened water equipment exceeding the standard:

1. The test at the sampling port of the soft water equipment is qualified, but the water hardness in the soft water tank exceeds the standard. The reasons for this phenomenon are as follows:

A. The regeneration cycle is set too large, or the measurement is not allowed due to the failure of the flow meter, so that the resin should not be regenerated in time when it should be regenerated, causing excess water to be injected into the soft water tank.

B. The time of forward washing is too short, so that the waste brine that should have been washed out during forward washing is partially taken to the soft water tank.

C. Too little water in the salt tank caused by unstable feed water pressure, too little salt absorption, and insufficient washing. Any one of them can cause the hardness of the effluent after the regeneration to exceed the standard and affect the water quality of the soft tank.

D. When there is very little salt in the salt box, it can not be added in time, resulting in a poor regeneration effect.

E. Improper operation. Close the water supply valve during a certain regeneration process.

Any of the above errors can cause a large amount of excess water to be injected into the soft water tank in a short time, and qualified soft water needs to be diluted for a long time before the water in the soft water tank can reach the standard again.

1. Multiple tests at the sampling port of the soft water equipment were unsatisfactory. This situation is divided into the first test of the water hardness of the newly installed soft water equipment and the hardness of the soft water equipment in use is discussed separately:

Reasons for the hardness test of newly installed soft water equipment for the first time:

a The O-ring at the junction of the central tube and the control valve has not formed a seal. At this time, you should check: whether the length of the central tube is sufficient and the outer diameter meets the requirements; whether you forgot to install the O-ring;

b The center tube is broken and cracked.

c The ratio of the feed water TDS value to the height of the resin layer is too large.

d The ratio of the feed water TDS value to the resin exchange capacity is too large.

e Reverse the water inlet and outlet.

Reasons for soft water hardness exceeding the standard for soft water equipment:

a The ratio of the feed water TDS value to the resin layer height or resin exchange capacity is too large. Compared with the first test of new resin water, the TDS value of water supply is more stringent when using soft water equipment. When the resin layer height is 1.5 meters, the total hardness is 13mmol / L, and the water supply TDS value 900mg / L, ensure that the soft water hardness is 0.03 mmol / L will be more difficult.

b Resin poisoning, resin exchange capacity reduction caused by aging. The soft water hardness exceeding the standard caused by this reason is a gradual process, not a sudden and apparent over-standard.

c Too little salt in the salt tank. When the amount of water in the salt tank is normal, and the height of the salt is less than 1/3 of the height of the water, the brine absorbed in the middle and later stages of the salt absorption step is likely to be unsaturated, resulting in the concentration of the brine diluted by the ejector below the regeneration requirement. , Affecting the regeneration effect.

d The total amount of water in the salt tank is too small. Our experience is that for every 100L of resin in the resin tank, the amount of water in the salt tank is about 35-40L. Too much below this standard will cause insufficient regeneration.

e Suction of salt water is too slow. In normal time, sufficient salt water cannot be inhaled. The reasons are as follows: the feed water pressure is too low; the debris such as sand and sand in the upper and lower water distribution are blocked; the waste water hose is deformed and bent. There are too many impurities in the resin layer; there are leakage points on the salt absorption pipeline to make the air sucked in; there are foreign objects in the ejector; the air check valve fails, closes or is blocked in advance; the ejector selection is too small.

1. Technical Parameters

1) The hardness of the raw water is 6 [H +] mmol / L, that is, 300mg / L (calculated as CaCO3); when the hardness of the raw water is 6-12 [H +] mmol / L, it is recommended to use two-stage softening or appropriately reduce the output of When the hardness of raw water is 12 [H +] mmol / L, it is recommended to use multi-stage softening or contact the company's engineering department to redesign.

2) Water hardness: 0.03 [H +] mmol / L (calculated as CaCO3);

3) Working pressure: 0.20--0.50Mpa

4) Working temperature: 2--49 ;

5) Turbidity of raw water: <5NTU;

6) System water consumption: <2%;

7) Water consumption <2% of water production Salt consumption <100 g / g equivalent

8) Power consumption: 10W-40W, because no salt pump is needed, the power consumption is only 1% of the average softening equipment

9) Working power: AC220V, 50Hz, single-phase three-wire system;

10) Working power consumption: <10W;

11) Periodic water production capacity: Q = V × E / (I raw water-I effluent);

Q: Periodic water production, m3 or t; V: Volume volume of resin, m & sup3;

I raw water: raw water hardness, [H +] mmol / L; I effluent: required water hardness, [H +] mmol / L

E: Working exchange capacity of resin, mmol / L, generally calculated according to 60%-70% of the total exchange capacity of the resin.

1. other reasons:

a There is a large amount of gas in the resin tank, which may come from the air in the feed water, or the air check valve is not closed tightly during the slow washing process.

b No large iodized salt is used.

c. Leakage inside the control valve: When the inside of the control valve is leaky, water will usually flow out of the soft water outlet and the waste water outlet at the same time. However, for 64D or 74A series, an internal leak may be formed through a small hole on the ceramic moving blade. This type of internal leakage is in the positive flushing position. Qualified soft water can be detected at the waste water outlet, but the hardness of the soft water exceeds the standard after it is transferred to the operating position.

Application area

Boiler soft water equipment can be widely used for softening the make-up water of systems such as steam boiler soft water, hot water boilers, exchangers, evaporative condensers, air conditioners, and direct-fired engines. It can also be used in the treatment of domestic water in hotels, restaurants, office buildings, apartments, households, etc. and in the softened water treatment of food, beverage, brewing, laundry, printing and dyeing, chemical and pharmaceutical industries.
