Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically a softening treatment system using seed crystals as a carrier. Background Technology

[0002] Crystallization granulation softening technology involves adding chemical agents and seed crystals to water, causing calcium ions in the water to react chemically and form calcium carbonate crystals that adhere to the surface of the seed crystals. Once the calcium carbonate particles reach a certain size, they are discharged from the equipment, thereby reducing the hardness of the water. This new softening technology does not produce byproducts and the discharged particles can be recycled.

The device includes a main body of a crystallization granulation softening bed, which, from bottom to top, has a seed discharge port, a water inlet, a multi-stage dosing port, a seed addition port, and a water outlet. The main body also has three viewing windows and three sampling ports from bottom to top. This patented multi-stage dosing crystallization granulation softening device offers advantages such as good water softening effect, small footprint, low maintenance cost, and ease of operation.

In response, we propose a softening treatment system with crystal seeds as carriers. Utility Model Content

[0023] To address the issues of inadequate water treatment methods, high workload, and impact on safe production caused by existing crystallization granulation softening equipment in practical use, please refer to... Figure 1 - Figure 4 This embodiment provides the following technical solution: A softening treatment system using seed crystals as carriers includes a water tank 1, a crystallization granulation fluidized bed 2, a seed crystal addition tank 3, and an acid-base addition tank 4.

[0024] A main outlet pipe 101 and a main inlet pipe 102 are provided on one side of the water tank 1. A drain pipe 201 is installed at the upper end of the crystallization granulation fluidized bed 2. The drain pipe 201 is connected to the water tank 1 and a granulation discharge pipe of the water tank 1 is set at the bottom. The equipment in the water tank 1 is electrically controlled by a solenoid valve. The equipment is arranged in sequence with a water distribution area, a drug distribution area, a granulation area and a clear water area. The ions in the water achieve chemical crystallization and granulation during the flow process. The formed particles settle to the bottom in the fluidization area and are finally discharged from the granulation discharge pipe at the bottom of the water tank 1.

[0025] Specifically, the equipment in water tank 1 is sequentially equipped with a water distribution zone, a chemical distribution zone, a granulation zone, and a clear water zone. Ions in the water achieve chemical crystallization and granulation during the flow process. The formed particles settle to the bottom in the fluidization zone and are finally discharged from the particle discharge pipe at the bottom of water tank 1. The softening system includes water tank 1, acid and alkali dosing tank 4, seed crystal dosing tank 3, particle discharge system, and control system. It fully realizes the automatic control of operations such as chemical dosing and particle discharge, which can significantly reduce the intensity of manual labor and improve the level of safe production.

[0026] Working principle: During operation, high-hardness water is introduced into the crystallization granulation fluidized bed 2. Alkali water is added through the acid-base addition tank 4, and seed crystals are added through the seed crystal addition tank 3. Below the seed crystal addition tank 3 is a filter plate 306 for filtering the seed crystals. A suitable filter mesh size is selected for the filter plate 306. The motor 310 drives the movable fan 311 to oscillate, causing the moving plate 312 to move horizontally back and forth, thereby moving the inclined filter plate 306. The filter plate 306 filters the seed crystals, causing them to fall into the mixing tank 301 for mixing. The mixture is then introduced into the crystallization granulation fluidized bed 2 via the mud pump 5 for further processing. The softening process achieves optimal working results, while unfiltered seed crystals fall to the return plate 305 and undergo secondary filtration via conveyor belt 304, reducing seed crystal waste and improving utilization. The high-hardness water in the crystallization granulation fluidized bed 2 undergoes a chemical reaction between the seed crystals and alkaline water, causing calcium ions in the water to form calcium carbonate crystals that adhere to the seed crystal surface. These crystals are then pumped into the water tank 1. Once the generated calcium carbonate particles reach a certain size, they are discharged from the particle discharge pipe at the bottom of the water tank 1 for recycling. The pH of the water in the water tank 1 is adjusted by adding acid water through the acid-base addition tank 4. After softening, the water is drained through the main outlet pipe 101.
