Description

Technical Field

[0001] This utility model relates to the technical field of sulfuric acid decolorization equipment, specifically an activated carbon dynamic adsorption sulfuric acid decolorization device. Background Technology

[0002] Sulfuric acid is an important chemical raw material in industrial production and is widely used in many fields. However, due to factors such as incomplete reaction of reactants, generation of intermediate products, and impurities in the raw materials during the preparation process, the produced sulfuric acid is often not pure enough and has a cloudy color. This cloudy sulfuric acid not only affects its appearance but may also have an adverse effect on its performance, causing many inconveniences to industrial production. It needs to be decolorized. However, existing decolorization devices can only perform single-layer adsorption, and the decolorization effect is not good. To solve the above problems, an activated carbon dynamic adsorption sulfuric acid decolorization device is needed.

[0003] An existing activated carbon dynamic adsorption sulfuric acid decolorization device cannot perform multi-layer adsorption decolorization of sulfuric acid during operation, resulting in poor decolorization effect and inability to filter and remove impurities from sulfuric acid. Therefore, there is an urgent need for an activated carbon dynamic adsorption sulfuric acid decolorization device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an activated carbon dynamic adsorption sulfuric acid decolorization device to solve the problems of existing activated carbon dynamic adsorption sulfuric acid decolorization devices being unable to perform multi-layer adsorption decolorization of sulfuric acid, resulting in poor decolorization effect and inability to filter and remove impurities from sulfuric acid.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an activated carbon dynamic adsorption sulfuric acid decolorization device, comprising a feeding sleeve, a retaining sleeve installed on the inner wall of the feeding sleeve, a filter screen installed on the inner wall of the retaining sleeve, a retaining strip installed on the outer wall of the retaining sleeve, a limiting spring installed on the inner wall of the feeding sleeve, a top rod installed on the outer wall of the limiting spring, an adsorption sleeve installed at the bottom of the feeding sleeve, a sealing strip installed on the inner wall of the adsorption sleeve, and an interception net installed at the bottom of the adsorption sleeve.

[0006] Preferably, the outer diameter of the ferrule matches the inner diameter of the feed sleeve, and the ferrule and the feed sleeve are movably connected.

[0007] Preferably, the locking strip is elastically configured and engages with the outer wall of the feed sleeve.

[0008] Preferably, the push rod forms a telescopic structure with the feed sleeve via a limiting spring, and the push rod is engaged with the adsorption sleeve.

[0009] Preferably, the adsorption sleeve is inserted into the feed sleeve, and the sealing strip is tightly fitted to the bottom of the feed sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model uses a feeding sleeve, a clip, a filter screen, and a clip to insert the clip into the feeding sleeve and fix it to the outer wall of the feeding sleeve. The filter screen can filter and remove impurities from the sulfuric acid, intercepting solid particles and mechanical impurities contained in the sulfuric acid, preventing these impurities from clogging the pores on the surface of the activated carbon and reducing the adsorption capacity of the activated carbon.

[0012] 2. This utility model, through the setting of a feeding sleeve, a limiting spring, a top rod, an adsorption sleeve, a sealing strip, and an intercepting net, presses the top rod inward, and then inserts the adsorption sleeve into the bottom of the feeding sleeve. At this time, the top rod is pushed out by the elastic force of the limiting spring, so that the top rod and the adsorption sleeve are locked and fixed. By splicing multiple adsorption sleeves, a multi-stage adsorption is formed, which greatly improves the decolorization effect and purity of sulfuric acid. At the same time, the cooperation of the limiting spring and the top rod facilitates the disassembly and assembly of the adsorption sleeve and the replacement of the internal activated carbon, making it more practical.

Through the feed sleeve 1, retaining sleeve 2, filter screen 3, and retaining strip 4, the retaining sleeve 2 is inserted into the feed sleeve 1, and the retaining strip 4 is engaged and fixed with the outer wall of the feed sleeve 1. The filter screen 3 can filter and remove impurities from the fed sulfuric acid, intercepting solid particles and mechanical impurities contained in the sulfuric acid, preventing these impurities from clogging the pores on the surface of the activated carbon and causing a decrease in the adsorption capacity of the activated carbon.

[0021] Please see Figures 1-4 A dynamic adsorption sulfuric acid decolorization device using activated carbon is disclosed. A limit spring 5 is installed on the inner wall of the feed sleeve 1, and a push rod 6 is installed on the outer wall of the limit spring 5.

Press the top rod 6 inwards, then insert the adsorption sleeve 7 into the bottom of the feed sleeve 1. At this point, the top rod 6 is pushed out by the elastic force of the limiting spring 5, causing the top rod 6 to engage and fix with the adsorption sleeve 7. By splicing multiple adsorption sleeves 7, a multi-stage adsorption is formed, greatly improving the decolorization effect and purity of sulfuric acid. Simultaneously, the combined use of the limiting spring 5 and the top rod 6 facilitates the disassembly and assembly of the adsorption sleeve 7 and the replacement of the internal activated carbon, making it more practical.

Then press the top rod 6 inward, and then insert the adsorption sleeve 7 into the bottom of the feed sleeve 1. At this time, the top rod 6 is pushed out by the elastic force of the limiting spring 5, causing the top rod... The 6 is engaged and fixed with the adsorption sleeve 7. Then, multiple adsorption sleeves 7 are spliced ​​together to form a multi-stage adsorption, which greatly improves the decolorization effect and purity of sulfuric acid. At the same time, the cooperation of the limiting spring 5 and the top rod 6 facilitates the disassembly and assembly of the adsorption sleeve 7 and the replacement of the internal activated carbon, making it more practical. Finally, the sulfuric acid to be decolorized is poured in from the top of the feed sleeve 1 and flows to the bottom activated carbon adsorption layer by gravity to achieve dynamic adsorption decolorization.
