Description

Technical Field

[0001] The utility model relates to the field of soft water supply, in particular to a soft water continuous supply system. Background Art

[0002] Coil equipment is often used in heat exchange. To prevent pipe scaling and ensure smooth operation of the equipment, the heat exchange medium flowing in the hose is generally soft water. For example, the steam generated by the coil in the steam generating equipment contains water, which will cause the water volume to decrease continuously during continuous operation, so soft water needs to be supplemented.

[0003] However, the return water utilization rate of the steam generating equipment in the prior art is low, and the water quality cannot be completely purified during the reciprocating cycle, resulting in the need for regular maintenance after long-term operation, and the maintenance frequency is high. In particular, the soft water supply system in the prior art has a single functionality and is highly dependent on continuous water replenishment, which results in certain waste. There is currently a lack of corresponding solutions to the above problems. Utility Model Content

[0008] The return water tank is connected to the soft water tank through a return water pipe, and a water pump is arranged on the return water pipe;

[0009] At the rear of the water pump, a first fine filter element is also arranged on the return water pipe;

[0010] The soft water tank is connected to an external water source and is connected to the soft water tank through a water supply pipe. A water pump, a coarse filter element and a second fine filter element are sequentially arranged on the water supply pipe from the water inlet end to the water outlet end.

[0011] The effect achieved in this way is that the return water from the steam-water separation device is re-filtered after secondary fine filtration, the water replenished in the soft water tank enters the soft water tank after secondary filtration, and water is replenished into the soft water tank through liquid level linkage control, and water is supplied from the soft water tank to the steam generating equipment.
