7、ion: 2% of water production; salt consumption:100 g / g-equivalent power consumption :3-40WAutomatic softener is softening and regeneration of run automatically control each step, and use of time, flow or other sensors, etc. to start regeneration.The basic form automatic softener is: FLECK or Autotr

8、ol multi-control valve, resin tank （with 001 * 7 resin）, salt boxes and piping systems.6, automatic softener features: Water softening process automation: process control devices via the device, to achieve ion exchange and resin regeneration process automation. High: water softener designed, effecti

9、ve work of the resin exchange capacity into full play. Provincial workers: no hand operation, easy installation. Non-toxic: lead-free brass or plastic valve body. Provincial Water: more than 98% of water. Power: As the use of siphon principle, renewable without salt pump.Easy to adjust: the regenera

11、onics and other industries.7, the maintenance of sodium ion exchange: ion exchanger is used to reduce the hardness of the water, raw water from the top down through the switch to soften the water contains magnesium, calcium, cation exchange resin with water, sodium ion exchange; raw water to be soft

12、ened a littlecalcium, magnesium and salt water （known as soft water）, so that the water is not easy to form carbonate and sulfate scale scale, can be used for boiler feed water and some industrial uses.Because sodium is very soluble in water.Will not form a hard scale in the boiler house, and easy t

13、o exclude, enter the sodium ion exchange water, shall be subject to clarification and filtration treatment, generally does not contain suspended solids.After softening by the switch, the residual hardness of not more than 0.03 mg / liter.Before emptying into the salt can not, so there will be air-re

14、sin, regeneration is not complete, not only will not increase water production good, but also may reduce the water yield and quality of water production. ion exchanger in the salt water is called regeneration, is cation exchange column for the purposes.High concentration of sodium ions to replace th

15、e branch of heavy metal ions.After half an hour rinse out the excess salt is to maintain the resin in a renewable good working condition.8, scale scale that is water base, that is, the state of water changes （especially when heated）, dissolved calcium （Ca2 +） and magnesium ions （Mg2 +）, and some of

16、the radical ion formation of insoluble incompound or mixture of water, the main ingredient is calcium carbonate.Poor thermal conductivity of the scale, only metal 1 / 200.Scale tend to form crystalline, hard, once formed, it is difficult to remove. How does the formation of scale?Scale formation is

17、a complex physical and chemical processes of reasons both internal and external.First, the water has calcium and magnesium ions and other heavy metal ions, is the root cause of the formation of scale is also called internal; the second is from the supersaturated solid matter precipitated in boiler w

18、ater and adhere to the metal heating surface is the formation of the external scale.When containing calcium and magnesium salts into the boiler water impurities, the absorption of high temperature flue gas heat to pass, calcium, magnesium impurities will be a chemical reaction to produce precipitati

19、on of insoluble material.With the continuous evaporation of water heaters gradually concentrated, when a certain concentration, precipitation will become a solid precipitated, attached to the drum, water wall tubes on the heating surface of the wall, forming a layer of film, impede heat transferThis

20、 layer of called the scale.As used in daily life, tap water, are a large number of dissolved calcium （Ca2 +） and magnesium ions （Mg2 +）, Beijing is often called hard water, is the truth.Such water in the heating, the calcium carbonate and magnesium ions （calcium carbonate and magnesium carbonate） so

21、lubility in water significantly reduced, most of which insoluble （calcium carbonate and magnesium carbonate） which would precipitate from the waterthe formation of precipitation, and then form a scale. What is the scale of the damage?Scale is a poor thermal conductivity of the material, only one-ten

22、th of the boiler to the number of steel per cent （the thermal conductivity of steel is 46.5 58.2w/m.k）, is the source of detrimental.In a variety of scale, the most hard silicate scale, thermal conductivity is very small, easily attached to the boiler heating surface evaporation surface of the stron

23、gest, is the most harmful kind of scale.Heating boilers, water heaters and hot water systems: Poor thermal conductivity of the scale, the waste of energy （natural gas or electricity）, the financial burden of the family; Lead to overheating of heat exchanger to reduce the service life, and even accid

24、ents; Scale can clog water pipes, causing poor water flow, or even forced to replace water pipes, causing damage to the decoration and other consequences.9, the scale of the boiler safety, economic operation of the hazard reduce the thermal efficiency, waste a lot of fuel.Boiler Health scale, the he

25、ating surface deterioration of the heat transfer performance, fuel combustion heat released can not be quickly passed to the boiler water, so a lot of heat was taken away by smoke, resulting in increased exhaust gas temperature, increased heat lossesthe boiler thermal efficiency.In this case, in ord

26、er to keep the boiler ratings, to be adding more fuel to the furnace and to increase the blast and the wind to strengthen combustion.The result is a large number of incomplete combustion of substances from the chimney, potentially increasing the fuel consumption.As we all know, the boiler furnace volume and grate area is certain, no matter how much adding fuel, fuel combustion is limited, so it is impossible for the thermal efficiency of the boiler increase.The more students boiler scale Results thick, the lower the thermal ef
