Energy-saving device for feeding regenerated liquid into sodium ion exchanger

Abstract

The invention relates to an energy-saving device for feeding regenerated liquid into a sodium ion exchanger. The energy-saving device comprises a salt pond, a water pumping pipe, a water storage barrel, a deflation valve, a water replenishing pipe and a salt liquid pump, wherein the salt pond is used for storing regenerated liquid; the tail end of the water pumping pipe extends into the salt pond; the head end of the water pumping pipe is communicated with the water storage barrel positioned outside the salt pond; a liquid inlet of the salt liquid pump is connected with the bottom of the water storage barrel; the deflation valve I and the water replenishing pipe are arranged on the water storage barrel; the tail end of the water pumping pipe is positioned above a horizontal line of the salt liquid pump; the water storage barrel and the water pumping pipe are fully filled with water through the water replenishing pipe, and a siphon structure is formed between the salt pond and the salt liquid pump, and the regenerated liquid in the salt pond is conveyed into the sodium ion exchanger by utilizing siphon. Compared with the prior art, the energy-saving device has the advantages that a siphon principle is utilized, so that the regenerated liquid in the salt pond can be directly pumped by the salt liquid pump; because a sea valve is additionally arranged on the water pumping pipe, the water replenishing pipe and the deflation valve are added on the water storage barrel, so that air in the water pumping pipe can be removed, and the salt liquid pump can be used for stably and effectively pumping the regenerated liquid into the sodium ion exchanger.

Description

technical field [0001] The invention relates to a liquid inlet device, in particular to a sodium ion exchanger regeneration liquid inlet device. Background technique [0002] In the softened water system, the role of the sodium ion exchanger is to remove calcium ions and magnesium ions in the water. [0003] Now the way to introduce the regeneration liquid into the sodium ion exchanger is: after the original salt is introduced into the salt pond, after being dissolved and saturated, the regeneration liquid is formed in the salt pond, and the regeneration liquid in the salt pond is pumped into the brine tank through the submersible pump, and then passed through the salt solution The pump pumps the regeneration liquid in the brine tank into the sodium ion exchanger. This method needs to use the submersible pump and the brine pump to transport it successively, requiring two processes, which increases labor and labor time. Contents of the invention [0004] The object of the ...
