Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam water tank technology, and specifically to a cleaning device for steam water tanks. Background Technology
[0002] Over long-term use, water tanks accumulate dirt and rust on their inner walls due to prolonged immersion in water and the sedimentation of impurities and minerals, affecting normal operation and water quality safety. Traditional cleaning methods involve manual scrubbing, which is inefficient and fails to thoroughly remove the dirt.
[0003] Acid washing, as a chemical cleaning method, can effectively remove dirt and rust from the inner wall of water tanks. However, existing acid washing methods only immerse all the acid washing solution in the water tank. This wastes the acid washing solution and leaves the dirt stuck on the inner wall of the water tank, resulting in low cleaning efficiency. Summary of the Invention
[0004] The purpose of this invention is to provide a steam tank cleaning device that avoids the shortcomings of the prior art. This steam tank cleaning device can continuously clean the inner wall surface of the tank, and has the advantages of saving cleaning fluid and high cleaning efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A steam tank cleaning device is provided, comprising a liquid tank containing a cleaning solution.
[0007] The liquid tank is connected to a circulation pump, and the circulation pump is detachably connected to a first pipeline. The first pipeline includes a main pipe, one end of which is connected to the circulation pump, and the other end of which is sealed. Several branch pipes are connected around the main pipe around its axis, and the branch pipes extend outward in a star-shaped pattern. Each branch pipe has a spray head at its port.
[0008] The liquid tank can also be detachably connected to a second pipe, which is connected to the bottom of the steam water tank to be cleaned.
[0009] In some embodiments, the second pipe is connected to a sedimentation tank, and the liquid tank is connected to the bottom of the steam tank through the sedimentation tank.
[0010] In some embodiments, a first pH meter is installed inside the liquid tank.
[0011] In some embodiments, a water tank is also included, which is detachably connected to the first pipe, and a second pH meter is provided at the outlet at the bottom of the water tank.
[0012] In some embodiments, the cleaning solution includes a 5% to 15% citric acid solution.
[0013] In some embodiments, the cleaning solution comprises a 10% to 20% hydrochloric acid solution.
[0014] In some embodiments, the main pipe includes a first main pipe section and a second main pipe section, the first main pipe section and the second main pipe section are connected by a bearing, the first main pipe section is connected to the circulating pump, and the branch pipe is connected to the second main pipe section.
[0015] The beneficial effects of this utility model's cleaning device for steam water tanks are as follows:
[0016] This invention relates to a steam water tank cleaning device. A circulating pump draws cleaning fluid from the tank, which is then distributed through a main pipe to branch pipes. Each branch pipe sprays the cleaning fluid onto the interior of the steam water tank, ensuring the fluid coats the inner wall. This eliminates the need to immerse the entire tank in the cleaning fluid, saving fluid and preventing contamination. Furthermore, the circulating cleaning fluid effectively removes solid contaminants, improving cleaning efficiency. The circulating spray method increases the contact area and reaction speed between the pickling solution and the dirt, shortening cleaning time and further enhancing efficiency. The pickling solution used in the cleaning process can be recycled, reducing waste and environmental pollution. Simultaneously, it improves the smoothness of the tank's inner wall after cleaning, reducing water resistance and lowering pump energy consumption. Attached Figure Description

[0024] Example 1
[0025] The steam water tank cleaning device disclosed in this embodiment, such as Figure 1 As shown, it includes a liquid tank 1, which is filled with cleaning fluid.
[0026] Liquid tank 1 is used to hold cleaning fluid.
[0027] The liquid tank 1 is connected to a circulation pump 2. The circulation pump 2 is detachably connected to a first pipe 3. The first pipe 3 includes a main pipe 4. One end of the main pipe 4 is connected to the circulation pump 2. The other end of the main pipe 4 is sealed. Several branch pipes 5 are connected around the main pipe 4 around its axis. The branch pipes 5 extend outward in a star-shaped pattern. Each branch pipe 5 has a spray head at its port.
[0028] The circulating pump 2 extracts the cleaning solution from the liquid tank 1. During cleaning, the circulating pump 2 is connected to the first pipe 3 so that the solution flows through the first pipe 3 to the main pipe 4. The main pipe 4 then distributes the solution to each branch pipe 5. Since the branch pipes 5 extend in a star-shaped pattern, the solution can be distributed to the inner wall of the steam water tank 7, thus fully covering the inner wall of the steam water tank 7 to be cleaned.
[0029] The liquid tank 1 is also detachably connected to a second pipe 6, which is connected to the bottom of the steam water tank 7 to be cleaned.
[0030] The second pipe 6 circulates the cleaning fluid that falls to the bottom of the steam water tank 7 back into the liquid tank 1. Since the steam water tank 7 is relatively large, in actual applications, the bottom of the steam water tank 7 will also be equipped with a drain port for draining the solution, which is connected to the second pipe 6.
[0031] In some embodiments, the second pipe 6 is connected to a sedimentation tank 8, and the liquid tank 1 is connected to the bottom of the steam water tank 7 through the sedimentation tank 8.
[0032] The sedimentation tank 8 can perform sedimentation treatment on the returned cleaning solution, avoiding the problem of the cleaning solution being affected by the precipitation of a large number of impurities.
[0033] In some embodiments, a first pH meter 9 is provided inside the liquid tank 1.
[0034] The first pH meter 9 is used to measure the pH of the cleaning solution in the liquid tank 1, so as to avoid failure due to excessive circulation and thus to refresh the cleaning solution in a timely manner.
[0035] In some embodiments, a water tank is also included, which is detachably connected to the first pipe 3, and a second pH meter 10 is provided at the outlet at the bottom of the water tank.
[0036] The water tank is used to provide cleaning water to flush against the inner wall of the tank, removing all remaining cleaning solution. The second pH meter 10 is used to detect the degree of rinsing. When the second pH meter 10 detects that the rinse water is neutral, the cleaning is complete.
[0037] In some embodiments, the cleaning solution includes a 5% to 15% citric acid solution.
[0038] In some embodiments, the cleaning solution comprises a 10% to 20% hydrochloric acid solution.
[0039] In some embodiments, the main pipe 4 includes a first main pipe section 4 and a second main pipe section 4, the first main pipe section 4 and the second main pipe section 4 are connected by a bearing 11, the first main pipe section 4 is connected to the circulating pump 2, and the branch pipe 5 is connected to the second main pipe section 4.
[0040] Example 2
[0041] Over long-term use, water tanks accumulate dirt and rust on their inner walls due to prolonged immersion in water and the sedimentation of impurities and minerals, affecting normal operation and water quality safety. Traditional cleaning methods involve manual scrubbing, which is inefficient and fails to thoroughly remove the dirt.
[0042] Acid washing, as a chemical cleaning method, can effectively remove dirt and rust from the inner wall of water tanks. However, existing acid washing methods only immerse all the acid washing solution in the water tank. This wastes the acid washing solution and leaves the dirt stuck on the inner wall of the water tank, resulting in low cleaning efficiency.
[0043] To address this technical problem, this embodiment discloses a cleaning device for steam water tanks. Please refer to [link / reference needed]. Figures 1-2 This includes the following steps:
[0044] Prepare the cleaning solution, store the cleaning solution in the tank, pump the cleaning solution to the inner wall of the steam water tank to be cleaned, cover the inner wall of the steam water tank, drive the cleaning solution to circulate and flush the inner wall of the steam water tank, so that the cleaning solution reacts with the dirt on the inner wall until the cleaning is completed.
[0045] Prepare the cleaning solution, which is suitable for cleaning the dirt inside the steam water tank. This solution is compatible with the dirt on the inner wall of the steam water tank, allowing for a better chemical reaction and cleaning effect. Then, use a circulating pump to extract the cleaning solution and spray it onto the inner wall of the steam water tank. Ensure the cleaning solution covers the entire inner wall of the tank, ensuring continuous and thorough reaction with the dirt, achieving a cleaning effect that can replace soaking.
[0046] Furthermore, the cleaning fluid is agitated during the circulation process.
[0047] In this embodiment, if the inner wall of the steam tank is made of stainless steel, the cleaning solution includes an 8% citric acid solution.
[0048] Stainless steel is mainly composed of elements such as iron, chromium, and carbon, and sometimes other elements such as nickel, molybdenum, and titanium are added. Therefore, citric acid solution can effectively remove dirt without damaging stainless steel.
[0049] In this embodiment, when preparing the hydrochloric acid solution, the hydrochloric acid is slowly injected into the water.
[0050] To avoid the formation of white mist during the mixing process, which could affect the accuracy of the mixing, the hydrochloric acid is poured into water for mixing.
[0051] In this embodiment, the cleaning solution further includes a corrosion inhibitor, the weight of which is 1% of the weight of the cleaning solution.
[0052] This corrosion inhibitor can be used to reduce the corrosion of water tank materials by pickling solutions.
[0053] In this embodiment, the corrosion inhibitor is thiourea or hexamethylenetetramine, and may also be other corrosion inhibitors.
[0054] In this embodiment, the rinsing flow rate of the cleaning fluid is 12 m³ / h, and the pressure is 0.3 MPa.
[0055] By adjusting the pickling solution flow rate and pressure, and controlling the residence time, the cleaning effect can be enhanced. The rinsing flow rate and pressure can effectively clean the dirt on the inner wall of the water tank.
[0056] In this embodiment, the cleaning time of the cleaning solution is 6 hours.
[0057] Maintaining this cleaning time ensures thorough cleaning of the inner surfaces of the water tank. During the circulation process, the cleaning solution needs to be allowed to settle, thus removing dirt promptly and ensuring the effectiveness of each cleaning cycle. In practical applications, the specific time depends on the concentration, temperature, and degree of dirt in the pickling solution.
[0058] In this embodiment, after the cleaning with the cleaning solution is completed, the inner wall of the steam tank is rinsed with clean water. The pH of the clean water rinsing solution is monitored in real time. When the pH is neutral, the rinsing is stopped.
[0059] After cleaning, drain the cleaning solution from the water tank and rinse the tank with plenty of clean water. Rinsing the inner wall of the steam tank with clean water can wash away the cleaning solution, thus preventing the cleaning solution from corroding the inner wall of the steam tank. At the same time, the pH of the rinsing solution is monitored in real time to determine the degree of rinsing. The closer the pH is to neutral, the cleaner the rinsing is.
[0060] For example, after cleaning, the cleaning solution is drained from the tank, the circulation pump is connected to the water tank, the valve is opened to drain the water, and the tank is rinsed with plenty of clean water to remove residual cleaning solution and reaction products. The flow rate of the rinsing water should be greater than the flow rate of the cleaning solution, and the rinsing time is generally 18 minutes, until the pH value of the rinsing water is close to neutral.
[0061] In this embodiment, when cleaning with cleaning fluid, the cleaning process ends when the inner wall of the steam tank is smooth and clean.
[0062] Determine whether the inner wall of the steam tank is clean by observing its appearance.
[0063] After cleaning, the inner wall of the water tank was inspected and found that the rust had been completely removed, and the inner wall of the tank was smooth and clean. At the same time, the pH value of the rinsing water was tested and found to be close to neutral, which meets the cleaning requirements.

[0070] Furthermore, the cleaning fluid is agitated during the circulation process.
[0071] In this embodiment, if the inner wall of the steam tank is made of carbon steel, the cleaning solution includes an 11.5% hydrochloric acid solution.
[0072] Carbon steel is an iron-based alloy containing carbon and other trace elements (such as manganese, silicon, and phosphorus). Therefore, a 15% hydrochloric acid solution can effectively remove dirt without damaging the carbon steel material.
[0073] In this embodiment, when preparing the hydrochloric acid solution, the hydrochloric acid is slowly injected into the water.
[0074] To avoid the formation of white mist during the mixing process, which could affect the accuracy of the mixing, the hydrochloric acid is poured into water for mixing.

Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.
[0139] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0140] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.
[0141] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
