Acid alkali storage tanks are mainly used to store various acidic and alkaline chemicals, playing a key role in many fields:
1、 Chemical industry
1. Raw material storage
In the chemical production process, many chemical reactions require the use of acids and bases as raw materials. For example, in the process of producing fertilizers, sulfuric acid is an important raw material used to convert phosphate rock into phosphoric acid. Acid alkali storage tanks can safely store large amounts of sulfuric acid, providing a stable supply of raw materials for fertilizer production. For alkaline substances such as sodium hydroxide, they are key raw materials in the production of chemical products such as detergents and papermaking. Acid alkali storage tanks can ensure their storage safety and stability.
These storage tanks can also be used to store intermediate and finished products. For example, in organic synthesis chemistry, some reactions produce acidic or alkaline intermediate compounds that need to be temporarily stored in acid-base storage tanks, waiting for the next reaction or purification. When producing chemical products such as pharmaceutical intermediates, acid-base storage tanks can store various high-purity acids and bases to ensure product quality is not contaminated.
2. Chemical reaction buffering
In the process of chemical reactions, the amount and rate of acid and base addition often need to be controlled correctly. The acid-base storage tank can serve as a buffer container to regulate the supply of acid and alkali. For example, in polymerization reactions, initiators (which may be acidic or alkaline substances) need to be added at the appropriate time according to the reaction process. Acid alkali storage tanks can provide the correct amount of initiator at the appropriate time, so that the reaction proceeds at the predetermined rate and direction. Moreover, when there are abnormalities in the reaction, such as high acid-base concentration that may cause side reactions, the acid-base supply in the storage tank can be temporarily suspended, playing a buffering and regulating role.
2、 Water treatment field
1. Drinking water treatment
In the process of purifying drinking water, acid-base regulation is an important step. For example, in the process of flocculation and precipitation of water, it is sometimes necessary to add acidic substances to adjust the pH value of the water, so that impurities in the water can precipitate better. The acid-base storage tank can store acids (such as hydrochloric acid) used to adjust the pH value, and add an appropriate amount of acid to the water according to the water quality test results. For some water sources containing heavy metal ions, adding alkaline substances (such as lime) can precipitate heavy metal ions, and the alkaline solution stored in acid-base storage tanks can meet this treatment requirement.
In the disinfection process, some disinfectants (such as sodium hypochlorite, whose aqueous solution is alkaline) also need to be stored in acid-base storage tanks. These storage tanks can ensure a stable supply of disinfectant, guarantee the disinfection effect of drinking water, and prevent disinfectant leakage from causing harm to the environment.
2. Industrial wastewater treatment
The composition of industrial wastewater is complex and often contains a large amount of acidic or alkaline substances. Acid alkali storage tanks can be used to store acid alkali reagents for neutralizing wastewater. For example, for acidic wastewater (such as electroplating wastewater), sodium hydroxide solution can be taken out from the acid-base storage tank for neutralization treatment; For alkaline wastewater (such as printing and dyeing wastewater), acidic reagents such as sulfuric acid can be used for neutralization. The existence of storage tanks ensures sufficient supply of acid-base reagents during the neutralization process, and can flexibly adjust the amount of acid-base added according to the actual pH value of the wastewater.
3、 Pharmaceutical industry
1. Drug synthesis and production
In the process of drug synthesis, acids and bases are often used as reaction reagents or catalysts. For example, in the synthesis process of aspirin, acidic catalysts are required. Acid alkali storage tanks can store these acidic or alkaline catalysts and supply them to the reaction system at the correct dosage and time, ensuring the smooth progress of drug synthesis reactions. For some drug purification steps that require alkaline conditions, such as separating alkaloids from plant extracts, the alkaline solution in the acid-base storage tank can provide a suitable reaction environment.
The quality and purity requirements for drugs are relatively high during the pharmaceutical process. The material and structural design of acid-base storage tanks can prevent external impurities from entering, ensuring the purity of stored acids and bases. This is crucial for producing high-quality drugs, as any impurities may affect the efficacy and safety of the drug.
2. Pre processing of drug packaging and storage
Before drug packaging, it may be necessary to adjust the pH value of the drug. For example, the pH value of certain liquid drugs needs to be stable within a certain range to ensure their shelf life and efficacy. Acid alkali storage tanks can store reagents used to adjust pH values and process drugs. Moreover, for situations where acidic or alkaline solutions are needed to clean packaging containers (such as glass bottles and plastic bottles), acid-base storage tanks can also provide corresponding cleaning solutions.
