Description

Technical Field

[0001] This utility model relates to the technical field of industrial cooling circulation treatment equipment, specifically a descaling device. Background Technology

[0002] During the operation of industrial cooling circulating water systems, scaling and algae growth on the inner walls of pipes have always been prominent technical challenges in the industry. Scale formation originates from dissolved calcium and magnesium ions in the water. Under the influence of factors such as temperature changes and pH fluctuations, these ions combine with anions such as carbonate and sulfate in the water to form insoluble salts such as calcium carbonate and calcium sulfate. These insoluble salts gradually precipitate from the water and adhere to the pipe surface, accumulating to form scale. Algae growth occurs because the circulating water system contains abundant nutrients such as nitrogen and phosphorus, and the ambient light and temperature conditions are ideal for algae growth and reproduction. Excessive algae growth adheres to the inner walls of pipes, intertwining with scale and further exacerbating the blockage problem. The consequences of these conditions are significant. On the one hand, it greatly increases the fluid resistance of the pipes, requiring the circulating water pump to consume more energy to maintain water circulation, leading to increased energy costs. On the other hand, the scale and algae layers formed on the heat exchanger surface act as insulation barriers, reducing heat exchange efficiency and consequently decreasing equipment operating efficiency. If these problems remain unresolved for a long time, not only will energy costs continue to surge, but in severe cases they may also cause equipment failures or even shutdowns, resulting in huge economic losses for enterprises.

[0003] Currently, metal catalyst technology is a common method used in the industry to solve the above problems. This technology is based on electrochemical principles. By installing a metal catalyst device inside the circulating water system pipeline, it causes the metal material to undergo an electrochemical reaction in the aqueous solution, releasing free electrons. These free electrons change the electrostatic potential of the fluid, causing polarization. This polarization effect effectively prevents positive and negative ions in the water from combining to form sparingly soluble salt crystals, while simultaneously destroying the crystal structure of existing scale, promoting its gradual dissolution and detachment, thus achieving scale prevention and removal. However, in practical applications, scale can also form inside the water tank and pipelines of purification units using this technology. This not only reduces the flow rate of the entire water passage but also decreases the purification efficiency of the purification unit for cooling circulating water, affecting the overall operating efficiency of the system. Utility Model Content

[0004] The purpose of this utility model is to provide a descaling device that aims to solve the scaling problem of the purification host in the above-mentioned technical problems, reduce the scaling problem of the core components of the entire purification system, and ensure the purification efficiency of the purification host for industrial cooling circulating water.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A descaling device, comprising:

[0007] Main unit chassis;

[0008] Multiple sets of processing pipelines are arranged side by side inside the main unit housing;

[0009] The first enclosed chamber and the second enclosed chamber are located at both ends of the main unit housing;

[0010] The two ends of the processing pipeline are respectively connected to the first closed chamber and the second closed chamber;

[0011] Both the first closed chamber and the second closed chamber are connected to one end of the descaling pipeline, and the other end of the descaling pipeline is connected to the reagent storage tank. The reagent storage tank introduces descaling agent through a pump, and the pump circulates the agent along the first closed chamber, the second closed chamber and the treatment pipeline.

[0012] This utility model also has the following technical features:

[0013] In one embodiment of this utility model, the medicine storage box is provided with two pipeline interfaces at both ends. The descaling pipelines of the first closed chamber and the second closed chamber are respectively connected to the two pipeline interfaces of the medicine storage box, and a first valve is provided on each of the descaling pipelines.

[0014] In one embodiment of this utility model, the main unit housing is provided with an inlet pipe and an outlet pipe at both ends. The inlet pipe is connected to the first closed chamber, and the outlet pipe is connected to the second closed chamber. The inlet of the inlet pipe is connected to the cooling water main pipe, and a second valve is provided on the inlet pipe and the outlet pipe respectively.

[0015] In one embodiment of this utility model, the inner cavity of the main unit housing near both ends is provided with a partition, and the partition cooperates with both ends of the main unit housing to form the first closed chamber and the second closed chamber, and both ends of the processing pipeline are respectively connected to the partition.

[0016] In one embodiment of this utility model, the first closed chamber and the second closed chamber are arranged vertically with the upper part larger than the lower part. Two sets of separation plates are provided at the bottom of the first closed chamber and the second closed chamber. The two sets of separation plates form a clamping cavity with the side walls of the first closed chamber and the second closed chamber. The end of the descaling pipeline is connected to the clamping cavity.

[0017] In one embodiment of this utility model, a plurality of connecting branch pipes are provided at intervals on the clamping cavity, and all the connecting branch pipes are connected to the descaling pipeline.

[0018] In one embodiment of this utility model, the bottoms of the first closed chamber and the second closed chamber are respectively vertically connected to multiple sets of connecting pipes, the lower ends of the multiple sets of connecting pipes are connected to a transition connecting chamber, and the water inlet pipe and the water outlet pipe are respectively connected to the transition connecting chamber.

[0019] In one embodiment of this utility model, mounting brackets are provided at both ends of the medicine storage box, and the mounting brackets are fixed on the main unit box.

[0020] In one embodiment of this utility model, the processing pipeline is fixed on a support plate, and the support plate is fixed inside the main unit housing.

[0021] Compared with existing technologies, the beneficial effects of this invention are reflected in the following: multiple sets of processing pipelines arranged side by side inside the casing are connected to the first and second closed chambers at both ends, forming a multi-path processing space. This structure, combined with the circulation system consisting of descaling pipelines, a reagent storage tank, and a pump, allows the descaling agent, driven by the pump, to enter the two closed chambers through the descaling pipelines and be evenly distributed to each set of processing pipelines. This increases the contact area between the agent and the inner walls of various components inside the main casing (including the processing pipelines, the first closed chamber, and the second closed chamber), allowing the agent to act on areas where scale may form from all directions. This avoids the problem of incomplete local descaling caused by uneven agent distribution in traditional devices, significantly improving the comprehensiveness and thoroughness of descaling.

[0022] The descaling agent circulates within the first and second closed chambers and the treatment pipelines. This circulation pattern continuously replenishes each part with fresh descaling agent, ensuring an effective concentration of the agent in the action area and enhancing its ability to dissolve scale. Simultaneously, the circulating agent exerts a certain scouring force on the inner walls of each component, helping to promptly remove dissolved scale and prevent its redeposition in the pipelines or chambers, thus improving descaling efficiency and shortening the descaling time.

[0023] By efficiently removing scale from these parts, the reduced water flow is avoided, ensuring the smooth operation of the entire water system. This maintains the purification efficiency of the main unit for cooling circulating water, ensuring stable and efficient operation of the equipment. It also reduces the risk of equipment failure or efficiency decline due to scale accumulation, extends the service life of the equipment, and reduces the company's maintenance and energy costs.

[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0031] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] It should be noted that metal catalyst technology for solving scale and algae problems in industrial cooling circulating water is based on electrochemical principles. By installing a metal catalyst device inside the circulating water system pipes, an electrochemical reaction occurs in the aqueous solution, releasing free electrons. These free electrons alter the electrostatic potential of the fluid, causing polarization. This polarization effect effectively prevents the combination of positive and negative ions in the water to form sparingly soluble salt crystals, while simultaneously disrupting the crystal structure of existing scale, promoting its gradual dissolution and detachment, thus achieving scale prevention and removal. However, in practical applications, scale buildup can also occur inside the water tank and piping of purification units using this technology. This not only reduces the flow rate of the entire water passage but also decreases the purification efficiency of the main unit for cooling circulating water, affecting the overall operating efficiency of the system. To address this, this utility model proposes a descaling device, comprising: a main unit housing 10; multiple sets of processing pipelines 20 arranged side-by-side within the main unit housing 10; a first closed chamber 11 and a second closed chamber 12 located at both ends of the main unit housing 10; both ends of the processing pipeline 20 are respectively connected to the first closed chamber 11 and the second closed chamber 12; both the first closed chamber 11 and the second closed chamber 12 are connected to one end of a descaling pipeline 30, and the other end of the descaling pipeline 30 is connected to a reagent storage tank 31. The reagent storage tank 31 introduces descaling reagent through a pump 32, and the pump 32 circulates the reagent along the first closed chamber 11, the second closed chamber 12, and the processing pipeline 20.

[0033] In one embodiment, see Figure 5 Metal catalyst devices can be installed inside the cavities of multiple treatment pipes 20. These devices can be existing electromagnetic excitation tubes. Through the generation of a constant magnetic field and an alternating magnetic field, the constant magnetic field weakens the hydrogen bond binding force of water molecules, releasing free water molecules and slowing down the scale formation process. The alternating magnetic field, with its constantly changing poles, primarily alters the polarity of scale-forming ions in the water, preventing scale formation.

[0034] In one embodiment, the first closed chamber 11 and the second closed chamber 12 are located at both ends of the main unit housing 10. The first closed chamber 11 and the second closed chamber 12 enable the main water pipe of the cooling circulating water to be connected to both ends of the multiple sets of treatment pipes 20. The metal catalyst devices are respectively installed in the treatment pipes 20, which can significantly improve the treatment efficiency and treatment effect of the cooling circulating water.

[0035] In one embodiment, the descaling agent can be a scale inhibitor, corrosion inhibitor, bactericide and algaecide, cleaning agent, pre-filming agent, etc. The cooling water mixed with the descaling agent is introduced into the first closed chamber 11, the second closed chamber 12 and the treatment pipeline 20 through the descaling pipeline 30 by the pump 32. This can effectively clean the entire interior of the purification host and avoid the problem of reduced pipeline size or reduced purification efficiency caused by scale buildup inside the purification host. The descaling agent can also enter the entire industrial cooling water system pipeline along the entire cooling circulating water pipeline to clean the cooling water, prevent the growth of scale and algae, and ensure the heat exchange effect of the industrial cooling system.

[0036] In one embodiment, the medicine storage box 31 is provided with two pipeline interfaces at both ends. The descaling pipelines 30 of the first closed chamber 11 and the second closed chamber 12 are respectively connected to the two pipeline interfaces of the medicine storage box 31. The descaling pipelines 30 are respectively provided with first valves 33.

[0037] In the above embodiments, see Figure 5 A set of descaling pipes 30 is provided on the first closed chamber 11, and a set of descaling pipes 30 is also provided on the second closed chamber 12. The two sets of descaling pipes 30 are respectively connected to two pipe interfaces of the agent storage tank 31, and a first valve 33 is provided on each of the two sets of descaling pipes 30. By opening the first valve 33 on the descaling pipe 30 of the first closed chamber 11, the pump 32 is started, so that the descaling agent is guided into the first closed chamber 11 and enters the second chamber through the processing pipe 20, ensuring the cleanliness of the entire purification host without the need to shut down the purification host.

[0038] In one embodiment, by closing the first valve 33 on the descaling pipeline 30 where the first closed chamber 11 is located, opening the first valve 33 on the descaling pipeline 30 where the second closed chamber 12 is located, and starting the pump 32, the descaling agent is directly delivered from the second closed chamber 12 to the cooling circulating water pipeline. The entire industrial cooling system is cleaned by chemical descaling, and the purification host does not need to be shut down.

[0039] In one embodiment, see Figure 1 and Figure 2 To further improve the cleaning effect of the purification host, the two ends of the host housing 10 are provided with a water inlet pipe 13 and a water outlet pipe 14. The water inlet pipe 13 is connected to the first closed chamber 11, and the water outlet pipe 14 is connected to the second closed chamber 12. The water inlet of the water inlet pipe 13 is connected to the cooling water main pipe. A second valve 18 is provided on the water inlet pipe 13 and the water outlet pipe 14 respectively.

[0040] In the above embodiment, the main unit housing 10 can be isolated from the main water pipe of the cooling circulating water through the water inlet pipe 13, the water outlet pipe 14 and the second valve 18. When the purification unit has a large scale problem, the first valve 33 on the descaling pipeline 30 on the first closed chamber 11 and the second closed chamber 12 can be opened by closing the water inlet pipe 13, the water outlet pipe 14 and the second valve 18, and starting the pump 32, so that the pipeline in the entire main unit housing 10 is filled with descaling agent, ensuring the cleaning effect of the entire purification unit.

[0041] In one embodiment, the descaling agent can be opened by opening the first valve 33 on the descaling pipeline 30 where the first closed chamber 11 is located, closed by closing the first valve 33 on the descaling pipeline 30 where the second closed chamber 12 is located, closed by closing the second valve 18 on the inlet pipe 13, opened by opening the second valve 18 on the outlet pipe 14, and started by pump 32. This allows the descaling agent to enter the second closed chamber 12 through the first closed chamber 11 and the treatment pipeline 20, and then enter the main pipeline of the cooling circulating water system through the outlet pipe 14, ensuring the cleaning effect on the entire system.

[0042] In another embodiment, the descaling agent can be reverse-cleaned by closing the first valve 33 on the descaling pipeline 30 where the first closed chamber 11 is located, opening the first valve 33 on the descaling pipeline 30 where the second closed chamber 12 is located, opening the second valve 18 on the inlet pipe 13, closing the second valve 18 on the outlet pipe 14, and starting the pump 32. This allows the descaling agent to enter the first closed chamber 11 through the second closed chamber 12 and the treatment pipeline 20, and then enter the main pipeline of the cooling circulating water system through the inlet pipe 13.

[0043] In one embodiment, see 5 and Figure 6 The main unit housing 10 has partitions 15 in the inner cavity near both ends. The partitions 15 cooperate with the two ends of the main unit housing 10 to form the first closed chamber 11 and the second closed chamber 12. The two ends of the processing pipeline 20 are respectively connected to the partitions 15.

[0044] In the above embodiment, the partition 15 is provided with holes in an array, and the two ends of the multiple sets of processing pipes 20 are respectively inserted into the holes to realize the connection between the two ends of the processing pipes 20 and the first closed chamber 11 and the second closed chamber 12.

[0045] In one embodiment, see Figure 6 The first closed chamber 11 and the second closed chamber 12 are arranged vertically with the upper part larger than the lower part. Two sets of separation plates 151 are provided at the bottom of the first closed chamber 11 and the second closed chamber 12. The two sets of separation plates 151 form a clamping cavity with the side walls of the first closed chamber 11 and the second closed chamber 12. The end of the descaling pipeline 30 is connected to the clamping cavity.

[0046] In the above embodiments, the descaling agent introduced through the descaling pipeline 30 is introduced from the clamping cavity, which can effectively cover the entire first closed chamber 11 or the second closed chamber 12 until it is filled, ensuring the cleanliness of the entire closed chamber.

[0047] Specifically, see Figure 6 The clamping cavity is provided with a plurality of connecting branch pipes 34 at intervals, and all the connecting branch pipes 34 are connected to the descaling pipeline 30.

[0048] In one embodiment, the descaling pipeline 30 is arranged around the outer wall of the first closed chamber 11 or the second closed chamber 12. When the pump 32 is started, the descaling pipeline 30 can enter each connecting branch pipe 34 along the descaling pipeline 30, thereby filling the first closed chamber 11 or the second closed chamber 12 until it enters the processing pipeline 20, forming a circulation of the descaling agent.

[0049] In one embodiment, to enable the first closed chamber 11 and the second closed chamber 12 to be connected to the inlet pipe 13 and the outlet pipe 14 respectively, multiple sets of connecting pipes 16 are vertically connected to the bottom of the first closed chamber 11 and the second closed chamber 12 respectively. The lower ends of the multiple sets of connecting pipes 16 are connected to the transition connecting chamber 17, and the inlet pipe 13 and the outlet pipe 14 are connected to the transition connecting chamber 17 respectively.

[0050] In one embodiment, in order to fix the medicine storage box 31, mounting brackets 35 are provided at both ends of the medicine storage box 31, and the mounting brackets 35 are fixed on the main unit box 10.

[0051] In the above embodiments, see Figure 1 and Figure 2 The medicine storage box 31 has a horizontally arranged cylindrical structure. The mounting bracket 35 includes a collar, which is fitted onto both ends of the medicine storage box 31. The mounting bracket 35 also includes a hook, which is fixed to the upper surface of the main unit box 10, thereby enabling reliable fixation of the medicine storage box 31.

[0052] In one embodiment, see Figure 7 In order to fix the multiple sets of processing pipelines 20 to the inner wall of the main unit housing 10, the processing pipelines 20 are fixed on the bracket plate 21, and the bracket plate 21 is fixed inside the main unit housing 10.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
