Problems solved by technology

The characteristics of this method are: less one-time investment and wide adaptability; but the operating cost is high when the water volume is large, and the application of water is greatly restricted due to the addition of chemical substances
[0009] Generally speaking, various existing softening treatment methods have their own characteristics. The softening treatment is affected by many factors. The conventional chemical softening method is simpl

Example Embodiment

[0028] Refer to the attached figure 1 As shown, the water softening device of the present invention includes a softening water tank 1, a water pump 3 and a deaerator 4, the softening water tank 1 is a fully enclosed water tank, and the water pump 3 and the deaerator 4 are arranged in a circulation communicating with the inner cavity of the softening water tank 1. on the pipeline.

[0029] In this embodiment, the softened water tank 1 adopts an anti-seepage treated concrete pool, a glass fiber reinforced plastic water tank, a carbon steel anti-corrosion water tank or a stainless steel water tank, a PE water tank, etc., for storing the hard water to be softened and the softened softened water.

[0030] The water pump 3 adopts the existing pump body such as a centrifugal pump, a plunger pump or a self-priming pump, and is used to pump the hard water to be softened in the softening water tank 1 into the deaerator 4, and make the liquid after passing through the deaerator 4 re-ente...

Abstract

The invention discloses a water softening apparatus, comprising a softening water tank, a water pump and a degassing unit; the softening water tank is a full-closed water tank, and the water pump and the degassing unit are disposed on a circulation pipeline communicated with an inner cavity of the softening water tank. The water softening apparatus also comprises an online monitor to monitor water hardness of hard water to be softened in real time and an online filter to further filter and remove precipitates. A water softening method is also disclosed. CO2 and O2 gases in the hard water to be softened are removed in the closed circulation pipeline, calcium carbonate and magnesium carbonate precipitates are formed in the hard water to be softened, the precipitates are filtered and removed by the degassing unit and the filter, the concentration of calcium and magnesium ions in the hard water to be softened is decreased, and the water is softened. The method is a purely physical water softening method, is free of secondary contaminations such as agent sludge, may soften water with little electricity consumed, and is green and free of regeneration; in addition, it is possible herein to implement adjustable control of water hardness through real-time monitoring of the online monitor.

Description

technical field [0001] The invention relates to the technical field of water softening, in particular to a water softening device and a water softening method. Background technique [0002] Natural water contains various salts that dissolve into cations and anions, mainly Ca 2+ , Mg 2+ 、Na + and HC0 3- , SO 4 2- , Cl - Wait. Water containing these salts, in the process of heating, evaporating and concentrating (such as boiler water), the Ca in the water 2 + , Mg 2+ The plasma continuously combines with some anions in the water to form insoluble substances and precipitates, and generates scale (commonly known as scale), which is attached to the heating surface of the boiler. Due to the poor thermal conductivity of scale, it hinders heat exchange and greatly reduces the thermal efficiency of the boiler. It wastes fuel and easily burns out parts, endangering safety and causing adverse consequences. In order to eliminate or reduce these hazards, it is necessary to rem...
