Description

Technical Field

[0001] This utility model belongs to the field of waste acid regeneration technology, specifically relating to an adsorption and purification component for waste acid regeneration. Background Technology

[0002] Waste acid regeneration is a process of purifying waste acid generated in industrial production using physical, chemical, or biological technologies. This process removes impurities such as heavy metal ions, organic matter, and suspended solids, restoring the acid's purity and usability. This technology typically employs methods such as adsorption, ion exchange, membrane separation, and distillation, combined with high-efficiency materials (e.g., activated carbon, molecular sieves, and resins loaded with nanomaterials) to achieve acid recycling, reduce hazardous waste emissions and raw material consumption. It is widely used in electroplating, metallurgy, and chemical industries, offering both environmental and economic benefits.

[0003] The main reason for using adsorption purification components for waste acid regeneration is that they can efficiently and selectively remove key pollutants from waste acid, restore the purity of the acid, and enable recycling. Conventional adsorption purification components use adsorbents to adsorb impurities inside waste acid, usually activated carbon. However, activated carbon requires high temperatures for continuous use, and the waste acid needs to be in full contact with the adsorbent to maximize waste acid regeneration. Conventional adsorption purification components are in a static state, which leads to low adsorption efficiency. Therefore, we propose an adsorption purification component for waste acid regeneration. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing an adsorption and purification component for waste acid regeneration, thereby solving the problems mentioned in the background art.

[0010] Preferably, the cleaning component includes a first scraper, a connecting plate, a second scraper, and a cleaning brush.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1.

At the same time, the cleaning component will also follow the movement of the moving component to clean the impurities adsorbed inside the moving component, preventing accumulation and blockage.

[0015] 2. The structure of the movable components facilitates the full movement of the composite adsorbent. The composite adsorbent, placed inside the movable components, is housed in an adsorbent tank. The composite adsorbent is activated carbon loaded with nanomaterials. By introducing nanoscale functional materials (such as nano-metal oxides, nanoparticles, and carbon nanotubes) into the surface or pores of the activated carbon, the adsorbent is formed. This modification significantly improves the adsorption performance of the activated carbon, making it superior in waste acid regeneration and other pollution control. The pump and discharge port can be activated at any time to discharge and replace the internal composite adsorbent. The drive motor provides the rotation basis for the rotating shaft, which in turn drives the connecting frame, which in turn drives the heating tube. This ensures that the composite adsorbent is fully mixed with the waste acid while the heating tube further enhances the adsorption effect of the activated carbon, thereby improving the waste acid adsorption efficiency of the device.

[0025] 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.

[0026] Example

[0027] Please see Figure 1-6 The technical solution provided in this embodiment is as follows:

[0028] An adsorption purification assembly for waste acid regeneration includes: an adsorption tower 1, with a feed inlet 2 fixedly connected to the top of the adsorption tower 1, and a movable cap 3 provided on the top of the feed inlet 2. The assembly is characterized by: a feed buffer 4 fixedly connected to the bottom of the feed inlet 2; multiple ceramic ball plates 5 fixedly connected to the inner wall of the adsorption tower 1; multiple stainless steel filter screens 6 fixedly connected to the inner wall of the adsorption tower 1; one of the multiple stainless steel filter screens 6 fixedly connected to the bottom of one of the ceramic ball plates 5, and another stainless steel filter screen 6 fixedly connected to the top of another ceramic ball plate 5; a movable assembly 7 fixedly connected between the multiple stainless steel filter screens 6; a cleaning assembly 8 provided on the inner wall of the movable assembly 7; a discharge pipe 9 fixedly connected to the bottom of the adsorption tower 1; and multiple support legs 10 fixedly connected to the bottom of the adsorption tower 1, the support legs 10 being triangularly distributed.

[0029] In this embodiment, the adsorption tower 1 utilizes its own space to provide a closed environment for the overall adsorption and purification of the device, and uses this environment to perform adsorption work in waste acid recovery. The feed inlet 2 provides an inlet for the waste acid, and after it is added, the movable cap 3 can be closed to ensure a seal and prevent the reaction of waste acid regeneration from affecting the outside. The feed buffer 5 can buffer the incoming waste acid. The ceramic ball plate 5, through its built-in ceramic balls, can buffer the impact of incoming liquid or gas on the adsorbent, protecting the adsorbent. At the same time, the stainless steel filter screen 6 through which the waste acid passes has excellent acid and alkali resistance, and can withstand the impact of the waste acid. It operates stably in acidic and alkaline environments, which enables it to effectively filter out impurities and particulate matter during waste acid recovery, ensuring the purity of the recovered liquid. Meanwhile, the movable component 7 uses its own structure to place the composite adsorbent, allowing the adsorbent to come into dynamic contact with the waste acid. During the use of the movable component 7, the cleaning component 8 also follows the movement of the movable component 7 to clean the impurities adsorbed inside the movable component 7. At this time, the acid material after adsorption will be further filtered through the stainless steel filter screen 6 and the ceramic ball plate 4, and discharged through the discharge pipe 9. The support leg 10 uses its own structure to provide support from the bottom.

[0030] The active component 7 includes an adsorbent tank 701, a pump 702, a discharge port 703, a drive motor 704, a rotating central shaft 705, a connecting frame 706, and a heating tube 707. The adsorbent tank 701 is fixedly connected between multiple stainless steel filter screens 6, the pump 702 is fixedly connected to one side of the adsorbent tank 701, and the discharge port 703 is fixedly connected to one side of the pump 702.

[0031] In this embodiment, the active component 7 places the composite adsorbent in the adsorbent tank 701. The composite adsorbent can be activated carbon loaded with nanomaterials. The composite adsorbent is formed by introducing nanoscale functional materials (such as nano metal oxides, nanoparticles, carbon nanotubes, etc.) into the surface or pores of the activated carbon. This modification significantly improves the adsorption performance of the activated carbon, making it perform better in waste acid regeneration and other pollution control. The pump 702 and the outlet 703 can be activated to suck out the used activated carbon in the adsorbent tank 701, making it convenient to replace with new composite activated carbon.

[0032] The drive motor 704 is fixedly connected to the bottom of the inner wall of the adsorbent tank 701, the rotating shaft 705 is set on the top of the drive motor 704, and the connecting frame 706 is fixedly connected to the surface of the rotating shaft 705. The shape and size of the connecting frame 706 match the inner wall of the adsorbent tank 701.

[0033] In this embodiment, the drive motor 704 can drive the rotating shaft 705 to rotate using its own structure, thereby driving the connecting frame 706 fixed on the surface of the rotating shaft 705 to rotate. This rotation allows the composite adsorbent inside the adsorbent tank 701 to move fully and absorb the incoming waste acid, thereby further improving the overall adsorption efficiency of the device.

[0034] Multiple heating tubes 707 are fixedly connected to the inner wall of the connecting frame 706, and the connecting frame 706 is evenly distributed on the inner wall of the heating tubes 707.

[0035] In this embodiment, the heating tube 707 is an electric heating tube, a tubular electric heating element composed of a metal tube spiral resistance wire and crystalline magnesium oxide powder, etc. It can be continuously heated by electricity to provide heat for the activation of the activated carbon inside the composite adsorbent, thereby further improving the adsorption effect of the device.

[0036] The cleaning component 8 includes a first scraper 801, a connecting plate 802, a second scraper 803, and a cleaning brush 804. The first scraper 801 is fixedly connected to one side of the connecting frame 706, and the second scraper 803 is fixedly connected to the other side of the connecting frame 706. The positions of the second scraper 803 and the first scraper 801 match the inner wall of the absorbent tank 701.

[0037] In this embodiment, the cleaning component 8 continuously rotates and scrapes the inner wall of the adsorbent tank 701 under the action of the first scraper 801 and the second scraper 803, which are driven by the rotating connecting frame 706, thereby scraping away any impurities that may be adsorbed by the waste acid and improving the cleanliness of the inner wall of the adsorbent tank 701.

[0038] The connecting plate 802 is fixedly connected between the first scraper 801 and the second scraper 803, and the cleaning brush 804 is fixedly connected to the surface of the connecting plate 802.

[0039] In this embodiment, the connecting plate 802 can connect and stabilize the first scraper 801 and the second scraper 803. At the same time, the cleaning brush 804 fixed on the surface will also clean the powder on the inner wall of the adsorbent tank 701 under the action of the connecting frame 706, thereby further improving the cleaning performance of the cleaning component 8.

[0040] Working Principle: This device provides a closed space for adsorption and purification through adsorption tower 1, while inlet 2 provides an entrance for waste acid. A movable cap 3 can be closed directly after feeding, ensuring a seal and preventing the reaction during waste acid regeneration from affecting the external environment, further improving the device's safety. Feed buffer 4 buffers the incoming waste acid, preventing direct impact on the device. Ceramic ball plate 5, with its built-in ceramic balls, buffers the impact of incoming liquids or gases on the adsorbent, protecting it. The stainless steel filter screen 6 has excellent acid and alkali resistance, enabling stable operation in acidic and alkaline environments. This makes it highly effective in waste acid recovery. It can effectively filter out impurities and particulate matter, ensuring the purity of the recovered liquid. The movable component 7 uses its own structure to place the composite adsorbent and ensures internal fluidity and heating, so that the adsorbent comes into contact with the waste acid in a dynamic manner, achieving continuous regeneration. At the same time, the cleaning component 8 will also follow the movement of the movable component 7 to clean the impurities adsorbed inside the movable component 7, preventing accumulation and blockage. The adsorbed acid material will be further filtered through the stainless steel filter screen 6 and ceramic ball plate 5. The finished product after this process will be discharged through the discharge pipe 9, and the support leg 10 can support the whole device from the bottom, thereby further improving the stability of the device.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
