Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment, and in particular to a centralized heating intelligent water treatment system. Background Technology
[0002] In the secondary water supply system of the centralized heating industry, plate heat exchangers at heating substations and radiators in residential rooms suffer from a common and serious problem of scaling. Scaling reduces heat exchange efficiency, directly leading to heat loss for heating companies. Plate heat exchangers require chemical and manual cleaning every year, increasing labor inspection and maintenance costs. Chemical agents also cause environmental pollution. Scaling also causes a drop in indoor temperature for residents, directly leading to an increase in resident complaints.
[0003] Currently, the traditional and commonly used descaling methods all employ chemical water treatment, namely "softening the makeup water + adding corrosion inhibitors." However, this approach still results in severe scaling on plate heat exchangers, fails to prevent corrosion, and can even lead to radiator blockages in residential users, increasing resident complaints. This is because chemical water treatment methods require the costs of corrosion inhibitors, consumables such as resin and salt for softening water, and the labor costs of professional water treatment engineers. Such costs are not cost-effective for centralized heating companies. Essentially, it reflects an imbalance between the economic viability and technical feasibility of chemical water treatment.
[0004] To address the aforementioned issues, there is an urgent need for a system that integrates intelligent monitoring and control while possessing efficient water treatment capabilities, in order to adapt to heating demands under complex operating conditions and ensure the system's efficient and stable operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] The embodiments of this utility model will be described below based on its overall structure.
[0028] This utility model relates to an intelligent water treatment device for a centralized heating system, which aims to solve the problems of water pollution and equipment blockage in the water treatment system by real-time monitoring and treatment of the water quality of the circulating water system.
[0029] For ease of description, the directional terms "upper," "lower," "left," "right," "front," "back," "inner," and "outer" used in this manual are based on the placement of the centralized heating intelligent water treatment system under normal installation and use conditions. Figure 1 As shown, "front" refers to the side closer to the inlet pipe of the plate heat exchanger, and "back" refers to the side farther away from the inlet pipe of the plate heat exchanger.
[0030] Reference Figure 1 and Figure 2 This utility model provides a centralized heating intelligent water treatment system, including an electromagnetic water wave processor 1, a water quality sensor 2, an automatic drain valve 3, a self-cleaning side-stream filter 4, an intelligent linkage controller 5, and a disturbance device 11. The electromagnetic water wave processor 1 is installed on the pipe before the plate heat exchanger in the heating station and is used for descaling and scale inhibition treatment of the circulating water. The water quality sensor 2 is also installed on the pipe before the plate heat exchanger in the heating station and is used to monitor the water quality parameters in the secondary network circulating water system 6 in real time. The automatic drain valve 3 is installed on the pipe before the plate heat exchanger in the heating station and is connected to the water quality sensor 2 via the intelligent linkage controller 5, used for draining water based on water quality monitoring data. The self-cleaning side-stream filter 4 is installed on the inlet and outlet pipes of the plate heat exchanger and is used to filter impurities in the circulating water and self-clean through backflushing.
[0031] The secondary network circulating water system 6 is equipped with a circulating pump 32 on the circulating water line and is connected to a water supply pipe. The water supply pipe is connected to a water supply tank 33 and a water supply pump 34.
[0032] The electromagnetic water wave processor 1 uses random pulse sequence alternating electromagnetic field technology to interfere with the formation of calcite and aragonite, causing calcite to transform into aragonite and remain suspended in a suspended state to be discharged with the water flow.
[0033] In practical implementation, the electromagnetic water wave processor 1 is a physical descaling and scale prevention device that uses a random pulse sequence of alternating electromagnetic fields to treat water. Its core working principle is as follows:
[0034] Descaling principle: The electromagnetic field disrupts the adhesion and accumulation properties of calcite scale. Before magnetization, the hard, dense, and strongly adhesive calcite scale (such as calcium and magnesium scale) transforms into a loose, porous, and easily powdered aragonite scale after magnetization. Simultaneously, hydrated ions, gaining kinetic energy from the electromagnetic field, repeatedly impact the scale on the pipe wall or heated surface, creating gaps. Under the influence of the alternating magnetic field, the scale gradually detaches from the heated surface or pipe wall, softening, thinning, and eventually peeling off.
[0035] 2. Scale Inhibition Principle: When water flows through a magnetic field, it is similar to a conductor cutting magnetic lines of force to generate an electric current, causing metal containers (such as pipes, heat exchangers, and boilers) to gain electrons and become negatively charged. According to the principle of repulsion between negative charges, negative ions such as hydroxide and bicarbonate in the water are less likely to adhere to the inner wall of the metal container. At the same time, water molecules gain energy, and the increased polarization intensifies the breaking of hydrogen bonds in some water molecules, producing more hydrogen ions and hydroxide ions. These ions combine with calcium and magnesium ions in the water to form slightly soluble calcium hydroxide and magnesium hydroxide, and easily soluble calcium bicarbonate, which are stably dispersed in the aqueous solution, forming suspended "soft scale." This interferes with the formation of calcium carbonate, thereby reducing crystallization and deposition on the surface of the container, achieving the purpose of scale inhibition.
[0036] A disturbance device 11 is installed in the front pipe of the plate heat exchanger of the heating station. The disturbance device adopts a detachable multi-layer spiral structure, specifically including an outer fixed shell and an inner rotatable spiral blade. The rotation disturbs the water flow in the plate heat exchanger of the heating station, making the aragonite calcium carbonate scale after being treated by the electromagnetic water wave processor easier to peel off.
[0037] The water quality sensor 2 is installed on the side wall of the inlet pipe of the plate heat exchanger, with its probe extending into the pipe to collect real-time water quality data of the circulating water, such as turbidity and hardness. The water quality sensor 2 is connected to the intelligent linkage controller 5 via a signal line, transmitting the collected data to the controller for processing. The intelligent linkage controller 5 includes a wireless signal transmission module and a data processing unit. The wireless signal transmission module interacts with the water quality sensor 2 and the automatic drain valve 3, while the data processing unit incorporates an adaptive adjustment algorithm module that dynamically adjusts the opening and closing frequency of the automatic drain valve 3 based on the data fed back from the water quality sensor 2.
[0038] The input terminal of the intelligent linkage controller 5 is also connected to a first temperature sensor 8 for detecting the primary supply water temperature of the plate heat exchanger 7 in the heating station, a second temperature sensor 9 for detecting the primary return water temperature of the plate heat exchanger 7 in the heating station, a third temperature sensor 10 for detecting the secondary supply water temperature of the secondary network circulating water system 6, and a fourth temperature sensor 11 for detecting the secondary return water temperature of the secondary network circulating water system 6.
[0039] The automatic drain valve 3 and the self-cleaning bypass filter 4 are integrated into a bypass module, which is connected to the inlet pipe of the plate heat exchanger via a shared pipe interface. The bypass module has a unified diversion interface, which is connected to the inlet pipe of the plate heat exchanger via a flange structure. The diversion interface contains a diversion guide plate, which is positioned opposite the drain channel of the automatic drain valve 3 and the inlet channel of the self-cleaning bypass filter 4, guiding water flow into the drain channel and the filter channel respectively.
[0040] Reference Figure 3 The piping of the self-cleaning side-stream filter 4 is made of corrosion-resistant polymer composite material, with an inner layer of nano-antibacterial coating 42 to reduce bacterial growth and corrosion on the inner wall of the pipe. The filtration unit of the self-cleaning side-stream filter 4 includes a multi-stage filter structure 43, which is connected to a backwash pipe 44. The opening and closing of the backwash pipe 44 is adjusted by an intelligent linkage controller 5. The intelligent linkage controller 5 is connected to the control terminal of the self-cleaning side-stream filter 4 and is used to adjust the backwash filtration frequency according to the upper and lower pressure thresholds within the pipe.
[0041] In specific implementation, refer to Figure 4 The electromagnetic water wave processor 1 includes a first electromagnetic water wave processor 111 and a second electromagnetic water wave processor 112. The first electromagnetic water wave processor 111 and the second electromagnetic water wave processor 112 work simultaneously, thereby enhancing the electromagnetic water wave processing effect.
[0042] In specific implementation, the electromagnetic water wave processor 1 includes a first electromagnetic water wave processor 111 and a second electromagnetic water wave processor 112. Either the first electromagnetic water wave processor 111 or the second electromagnetic water wave processor 112 can work. For example, when the first electromagnetic water wave processor 111 is in a fault or maintenance state, the second electromagnetic water wave processor 112 can be activated. Either the two electromagnetic water wave processors 111 and 112 can also be selected to work, thereby ensuring the long-term effective operation of the water treatment system.
[0043] In terms of working principle, the intelligent water treatment system for centralized heating of this utility model achieves intelligent management of circulating water quality through the coordinated operation of various components. First, when circulating water enters the pipe before the plate heat exchanger, the disturbance device disturbs the water flow through its multi-layer spiral structure and water flow disturbance channel 15, and combined with the effect of electromagnetic waves, destroys the scale crystal structure, preventing scale formation on the plate heat exchanger. Subsequently, the water quality sensor 2 monitors the water quality parameters in real time and transmits the data to the intelligent linkage controller 5. When the water quality parameters exceed the set threshold, the intelligent linkage controller 5 controls the automatic drain valve 3 to open through the adaptive adjustment algorithm module 53 to perform a drain operation. At the same time, the self-cleaning side-filter device 4 filters impurities in the circulating water through the multi-stage filter structure 43, and when the pressure reaches the set threshold, the intelligent linkage controller 5 triggers the backflushing pipe 44 to perform self-cleaning, ensuring that the turbidity of the circulating water meets the standard.
[0044] In one specific embodiment, the intelligent water treatment system for centralized heating of this utility model is applied to the secondary circulating water system 6 of a heating station in a thermal power plant. The outer fixed shell 11 of the disturbance device has a diameter of 200 mm, and the inner spiral blades 12 are provided with 6 water flow disturbance channels 15, each channel being approximately 10 mm wide. The water quality sensor 2 is a model with a turbidity detection accuracy of 0.1 NTU, installed on the left side wall of the pipe before the plate heat exchanger. The automatic drain valve 3 and the self-cleaning side filter 4 are integrated into the bypass module 6, and the diversion interface of the bypass module 6 is connected to the main pipeline through a DN50 flange structure. The multi-stage filter structure 43 of the self-cleaning side filter 4 includes 3 stages of filter screens with pore sizes of 100 micrometers, 50 micrometers, and 20 micrometers, respectively. During system operation, the intelligent linkage controller 5 adjusts the opening and closing frequency of the automatic drain valve 3 every 2 hours based on the data fed back by the water quality sensor 2, and triggers the backflushing operation of the self-cleaning side filter 4 every 6 hours based on the pressure sensor data.
[0045] As an alternative, the inner spiral blades 12 of the disturbance device can be connected to the outer fixed housing 11 via a threaded connection to adapt to disassembly requirements in different pipeline installation environments. Furthermore, the multi-stage filter structure 43 of the self-cleaning side-stream filter 4 can be adjusted to a 2-stage or 4-stage filter structure according to the characteristics of impurities in the circulating water to balance the filtration effect and backwash frequency.
[0046] In summary, this utility model discloses a centralized heating intelligent water treatment device, which solves the problems of water pollution and equipment blockage in the water treatment system by integrating an electromagnetic water wave processor, a water quality sensor, an automatic drain valve, and a self-cleaning side-stream filter.
[0047] Furthermore, this utility model utilizes a detachable multi-layer spiral structure and a water flow disturbance channel in the disturbance device to effectively prevent scale deposition; the water quality sensor monitors water quality data in real time, and works in conjunction with the automatic drain valve and self-cleaning side-stream filter through an intelligent linkage controller to dynamically adjust the drain and backwash frequency to ensure water quality stability; the integrated design of the bypass module and the application of corrosion-resistant materials further enhance the convenience and durability of the device.
[0048] Furthermore, this utility model realizes the intelligent and efficient water treatment process, significantly reduces the maintenance cost of the heating system, extends the service life of the equipment, and provides a stable and reliable water quality guarantee for the centralized heating system;
[0049] Furthermore, by setting up a first electromagnetic water wave processor and a second electromagnetic water wave processor, the two electromagnetic water wave processors can work simultaneously to enhance the electromagnetic water wave treatment effect; alternatively, one of the two electromagnetic water wave processors can be selected to work to ensure the long-term effective operation of the water treatment system.
[0050] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
