Problems solved by technology

However, after chemical polishing, water washing will bring out a large amount of acid. At present, chemical polishing of one ton of aluminum requires about 200 kilograms of mixed acid. It is estimated that hundreds of millions of acids are wasted across the country. Acid will pollute the environment and needs to be neutralized with a large amount of alkali, but the phosphate and sulfate radicals in it cannot be completely removed, and a large amount of manual intervention is required. Therefore, efficient and automatic acid recovery and treatment equipment is currently a subject area that needs to be developed

Embodiment 1

[0020] Such as figure 1 , 2 The shown intelligent acid recovery processing device includes an evaporation tank, and the evaporation tank includes an evaporation chamber 1 and a heating chamber 2; the heating chamber 2 surrounds and is closely attached to the outer edge of the evaporation chamber 1; the heating chamber 2 There is a heating cavity inside, and the periphery of the heating chamber 2 is provided with a high-temperature steam inlet pipe 21 and a condensed water outlet pipe 22 communicating with the heating chamber; the top of the evaporation chamber 1 is provided with a feed port 11, and the bottom is provided with an outlet pipe The feed port 12 and the top of the evaporation chamber 1 are also provided with a juice vapor outlet pipe 13 .

[0021] Among them, the high-temperature steam enters the heating cavity inside the heating chamber 2 from the high-temperature steam inlet pipe 21, and is liquefied into condensed water after heat exchange, and the condensed wa...

Embodiment 2

[0023] Such as figure 1 , 2 , A kind of intelligent acid recovery treatment device shown in 3, comprises evaporation tank, described evaporation tank comprises evaporation chamber 1 and heating chamber 2; Described heating chamber 2 surrounds and is close to the outer edge of evaporation chamber 1; The inside of the heating chamber 2 has a heating cavity, and the periphery of the heating chamber 2 is provided with a high-temperature steam inlet pipe 21 and a condensed water outlet pipe 22 communicating with the heating chamber; the top of the evaporation chamber 1 is provided with a feed port 11, and the bottom is provided with a There is a discharge port 12, and the top of the evaporation chamber 1 is also provided with a juice vapor outlet pipe 13.

[0024] Wherein, the high-temperature steam enters the heating cavity inside the heating chamber 2 through the high-temperature steam inlet pipe 21, and is liquefied into condensed water after heat exchange, and the condensed wa...

Embodiment 3

[0037] The intelligent acid recovery treatment method includes the following steps: 1) Inject waste liquid from the feed inlet set on the top of the evaporation chamber; 2) Inject high-temperature steam into the heating chamber from the high-temperature steam inlet; 3) After heating, the juice produced after evaporation The steam is discharged from the juice vapor outlet pipe at the top of the evaporation chamber into the condenser pipe, and is drawn out by a vacuum pump, and the vacuum degree of the evaporation chamber is maintained at -75kpa~-65kpa through the vacuum pump; 4) The finished acid is collected from the outlet at the bottom of the evaporation chamber .

[0038] In step 4), the intelligent control circuit reads the liquid level gauge and the vacuum gauge to calculate the volume, reads the data weighed by the weighbridge, and calculates the material density through the intelligent circuit, so as to determine whether the material concentration is up to standard. Afte...

Abstract

The invention relates to an intelligent acid recovering and treating device and an intelligent acid recovering and treating method. The intelligent acid recovering and treating device comprises an evaporating pot, wherein the evaporating pot comprises an evaporation chamber and a heating chamber, the heating chamber surrounds and is clung to the outer edge of the evaporation chamber, and a heatingcavity is formed in the heating chamber; a high temperature steam inlet pipe communicated with the heating cavity and steam condensating water outlet pipe are arranged on the peripheral edge of the heating chamber; and a feed opening is formed in the top of the evaporation chamber, a discharge opening is formed in the bottom of the evaporation chamber, and a juice steam outlet pipe is further arranged at the top of the evaporation chamber. The intelligent acid recovering and treating device disclosed by the invention is high in automation degree, and externally-discharged acid generated during the production of enterprises can be efficiently recovered.

Description

technical field [0001] The invention relates to the field of acid recovery and treatment, in particular to an intelligent acid recovery and treatment device and an intelligent acid recovery and treatment method. Background technique [0002] Acid is widely used in chemical, steel and other industries. In many production processes, the utilization rate of acid is very low, and a large amount of acid is discharged along with the acid-containing wastewater. If the waste water is discharged into the environment without treatment, it will not only acidify the water body or soil, cause harm to the ecological environment, but also waste a lot of resources. In addition to being acidic, waste acid and acid wastewater also contain a large amount of impurities, which will also cause environmental pollution. The existing aluminum chemical polishing industry needs to use a large amount of phosphoric acid and sulfuric acid. However, after chemical polishing, water washing will bring ou...
