Description

Technical Field

[0001] The invention relates to the technical field of water softening equipment, in particular to an ion exchange resin process boiler water softening device. Background Art

[0002] Ion exchange is a process that removes hardness from water by exchanging hardness ions such as calcium and magnesium in the water with sodium ions (Na+) on the surface of the resin. As water flows through the exchanger filled with resin, the sodium ions on the resin will exchange with the calcium and magnesium ions in the water, thereby reducing the hardness of the water. This prevents scale accumulation in boiler pipes and equipment, ensures efficient operation of the boiler and extends the service life of the equipment.

[0003] Although the existing ion exchange resin process boiler water softening device can effectively remove hardness ions such as calcium and magnesium in water, it has some limitations and disadvantages for the pretreatment of iron and manganese metal ions. When iron and manganese ions exist in a dissolved state in water, they may be deposited or oxidized on the surface of the resin after the exchange process of the ion exchange resin, causing the resin to be poisoned or ineffective. Iron ions are particularly prone to react with the exchange groups in the resin to form sediments, which will block the pores of the resin, reduce its exchange capacity, and even cause damage to the resin.

[0004] In summary, the prior art lacks a technology for pre-treating iron and manganese metal ions in water. Summary of the invention

[0012] Preferably, a tension spring is fixedly connected to the bottom end of the sealing plug, the other end of the tension spring is fixedly connected to the inner wall of the processing seat, a conical head is fixedly connected to the lower surface of the sealing plug, and the outer wall of the conical head is in sliding contact with the inner wall of the bottom end of the pretreatment tank.

[0014] Preferably, a rotating shaft is rotatably connected to the inner wall of the secondary processing box, one end of the rotating shaft located in the secondary processing box is connected and fixedly provided with a filter residue processing plate, and the outer end of the rotating shaft is connected and fixedly provided with a transmission wheel, and the transmission wheel is meshed with an annular rack for transmission.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting up an oxidation mechanism, heated chlorine and air can be injected into the water before the resin tank performs water softening treatment. The heated chlorine can increase the reaction rate and promote the oxidation reaction. It can pre-treat the iron and manganese metal ions in the water and convert them into insoluble oxides, thereby avoiding their deposition or oxidation on the resin, reducing resin poisoning and clogging, and extending the service life of the resin. It can improve the working efficiency of the ion exchange resin in the subsequent soft water treatment process, and reduce the maintenance frequency of the soft water device, such as reducing the need to clean and replace the resin, and reducing operating costs;

[0017] 2. By opening multiple water tanks on the intermittently rotating treatment seat, batch oxidation pretreatment can be achieved. The water in each water tank can be fully exposed to chlorine and air to ensure that the iron and manganese ions are completely oxidized into precipitates. The intermittent rotation allows each water tank to be fully treated, and the oxidation process is more uniform, ensuring that the iron and manganese metal ions in each batch of water can be effectively removed. At the same time, by setting a conical head, the sealing plug is automatically opened for drainage. The automatic drainage design not only improves the efficiency of oxidation pretreatment, but also reduces the need for manual intervention and maintenance;

[0018] 3. By setting up a secondary treatment box, the arc-shaped filter is used to separate the oxidized iron and manganese metal ion precipitates. At the same time, when the treatment seat rotates, it can drive the filter residue treatment plate to rotate, and push the precipitate off the arc-shaped filter to avoid the accumulation of precipitate on the filter surface and cause poor filtration. It not only improves the continuity and efficiency of filtration, but also ensures that the filter surface is always kept clean, thereby extending the service life of the equipment.
