Technical Field

[0001] The utility model relates to the technical field of salt-free softened water treatment, in particular to a novel salt-free softened water treatment device. Background Art

[0002] Salt-free softened water is a specially treated water quality. It mainly removes hardness ions, especially calcium ions and magnesium ions, from water by physical or chemical methods without using salt or other chemicals. Salt-free softened water technology has a wide range of applications, including household, commercial and industrial fields. In the household field, salt-free softened water can be used for daily water such as laundry, bathing, and washing dishes; in the commercial field, salt-free softened water can be used for water in restaurants, hotels, hospitals and other places; in the industrial field, salt-free softened water can be used for water in boilers, cooling systems, production lines and other equipment.

[0003] However, in existing treatment devices, resin is the core part of the salt-free softening water treatment device, which is used to adsorb and exchange hardness ions in water. However, the resin may fail due to long-term use or water quality problems, resulting in a decrease in the softening effect, so it is necessary to improve it. Utility Model Content

[0004] The purpose of the utility model is to provide a novel salt-free softening water treatment device to solve the problem that in the existing treatment device, the resin is the core part of the salt-free softening water treatment device and is used to adsorb and exchange hardness ions in water. However, the resin may become ineffective due to long-term use or water quality problems, resulting in a decrease in the softening effect.

[0006] Furthermore, the first pre-processing device and the second pre-processing device adopt a bottom-in-top-out method.

[0007] Furthermore, the structure of the HRCC device is composed of a tank body, a black two-way pipe, a central pipe and upper and lower water distributors.

[0008] Furthermore, after being pre-treated, the raw water enters through the black two-way water inlet at the top of the HRCC device, and is sent to the lower water distributor at the bottom through the central pipe, and the water flow then rises upward.

[0009] Furthermore, the HRCC device is placed at the front end of the membrane device.

[0010] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0011] The water inlet method at the HRCC device adopts the backwash method of bottom-in and top-out. This method can make the filter material contact with water in all directions and make it in a boiling state. The water path is changed according to the water inlet method, so as to protect the use of the rear membrane group and extend the service life of the membrane group.

[0015] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] The utility model provides Figure 1 and Figure 2 As shown:

[0017] A novel salt-free softened water treatment device comprises a first pretreatment device 1, and further comprises a second pretreatment device 2, a HRCC device 3, an intermediate water tank 4, a water pump 5 and a membrane device 6 connected in sequence, wherein the drain outlet of the first pretreatment device 1 is connected to the water inlet of the second pretreatment device 2, the drain outlet of the second pretreatment device 2 is connected to the intermediate water tank 4, and a water pump 5 is provided at the connection between the intermediate water tank 4 and the membrane device 6;

[0018] In this embodiment, the water inlet method adopts the bottom-in-top-out backwash method at the HRCC device 3. This method can make the filter material contact with water in all directions and make it in a boiling state. The water path is changed according to the water inlet method; a new HRCC filter material is used, and the nuclear-assisted crystallization technology is applied. The uniqueness of this product is that it can convert calcium and iron hardness into insoluble microcrystals, protect the use of the back-end membrane group, and extend the service life of the membrane group. This device uses a brand-new filter material, which is a highly active special solid heterogeneous catalyst. It uses NAC nuclear-assisted crystallization technology, with polystyrene as the framework, ceramic powder for surface treatment, and finally a special modified water treatment material. Compared with the current resin equipment, it can prevent scale without adding any chemical agents; no consumption; no salt regeneration; no manual maintenance; no electricity or valve control; no wastewater generation; mild reaction, adjustment of pH value to weak alkalinity, etc.

[0019] The first pre-treatment device 1 and the second pre-treatment device 2 adopt a bottom-in-top-out method;

[0020] In this embodiment, the first pretreatment device 1 and the second pretreatment device 2 can remove impurities in the water, paving the way for subsequent treatment. The HRCC device 3 catalyzes the raw water to exist in the water in a stable form, and the membrane device 6 removes the substances produced in the water to obtain purified water. In the bottom-in and top-out manner, the water pressure can completely flush the filter material to a boiling state so as to achieve full contact with the water.

[0021] The structure of the HRCC device 3 is composed of a tank body 7, a black two-way pipe 8, a central pipe 9 and upper and lower water distributors 10. After being pre-treated, the raw water enters the HRCC device 3 from the black two-way water inlet at the top, and is sent to the lower water distributor at the bottom by the central pipe. The water flow then rises upward, and the HRCC device 3 is placed at the front end of the membrane device 6.

[0022] In this embodiment, the raw water of the HRCC device 3 is fully in contact with the filter material for 7-10 seconds, so that the raw water is fully catalyzed. The water catalyzed by the HRCC device 3 has formed a stable molecular structure before being heated. Calcium carbonate and magnesium exist in the water in the form of submicron crystals and no longer adhere to the inner wall of the container or the pipe. Calcium and magnesium are retained and scale is prevented, thereby effectively extending the service life of the membrane group.
