[0027] like Figure 1-Figure 5 As shown, the utility model proposes a coal mine boiler pre-ion exchange water purification device, which includes a primary shell 1, a secondary shell 11 and a filter cartridge 12. A primary filter assembly is provided in the primary shell 1, and a water inlet 2 and a water outlet 4 are respectively provided on the primary shell 1. A connecting end 5 is provided on the secondary shell 11. The water outlet 4 and the connecting end 5 are interconnected by a flange. A secondary filter assembly is provided inside the secondary shell 11.

[0028] Based on Example 1:

[0029] During use, the utility model of the coal mine boiler pre-ion exchange water purification device pre-treats the water entering the coal mine boiler through the first-level filter component in the first-level shell 1, thereby removing impurities such as suspended matter, colloids, and organic matter in the water, reducing the load of subsequent processing units;

[0030] The water treated by the primary filter assembly enters the secondary housing 11, and then enters the filter cartridge 12 to contact the ion exchange resin layer. The adsorption of the ion exchange resin removes hardness ions and heavy metal ions in the water. The treated water finally enters the coal mine boiler through the discharge port 6.

[0031] Secondly, when the ion exchange resin reaches a saturated state, the recoil end 7 and the sewage end 14 are opened, the connection end 5 and the discharge end 6 are closed, and then the regeneration liquid (usually an acid or alkaline solution) is introduced into the interior of the secondary shell 11 through the recoil end 7. The regeneration liquid exchanges with the ions on the resin to restore the adsorption capacity of the resin. At the same time, the wastewater is discharged through the sewage end 14.
