What are the working principles and application industries of chemical dosing systems

Chemical dosing systems are used to add chemicals to industrial production processes. These systems often require high precision and reliability, as the addition of pharmaceuticals must be precisely controlled to meet production requirements and safety standards. The following is the basic working principle of the chemical dosing system:

▪Drug storage and supply:

First, chemicals are usually stored in specialized containers or tanks. The dosing system needs to supply medicines from these storage devices. The supply process can be carried out by liquid pumps, screw feeders, gravity conveying, etc., depending on the nature and needs of the drug.

▪Metering and control:

The dosing unit needs to accurately measure and control the amount of medicine added. This is usually achieved through instruments such as flow meters, weighing sensors, level sensors, etc. The control system will adjust the addition rate and amount of drugs based on the production process requirements and formula, as well as sensor feedback signals.

▪Mixing and Dispersing:

Once pharmaceutical products are delivered to their destination, they often need to be mixed or dispersed with other ingredients. This can be achieved through equipment such as agitators, mixing tanks, mixers, etc. to ensure that the drug product is evenly distributed throughout the production process.

▪Monitoring and feedback control:

Chemical dosing machine are usually equipped with monitoring equipment to monitor parameters during the production process, such as temperature, pressure, pH value, etc. This data can be used in feedback control systems to ensure that the production process is always within safe limits and that required quality standards are maintained.

▪Safety measures:

Automatic dosing system often have multiple safety measures to prevent accidents and leaks. This includes leak detection, emergency shutdown systems, fire protection systems, and more.

▪Recording and reporting:

Systems typically record drug usage, production parameters, and event logs. This data can be used for quality control, compliance and traceability requirements.

In general, the working principle of chemical dosing systems involves precise drug supply, measurement, control, mixing and monitoring to ensure that the safety, efficiency and quality of drugs during the production process meet requirements. These systems are usually computer controlled and equipped with multiple safety and monitoring devices to ensure the reliability and stability of the production process.

Therefore, auto dosing system are widely used in many industries. Some of the main application industries include:

▪Pharmaceutical industry:

The pharmaceutical industry is one of the main application areas of chemical dosing systems. These systems are used to add precise doses of active pharmaceutical ingredients into the pharmaceutical process to prepare pharmaceutical formulations, ensuring the quality and consistency of pharmaceutical products.

▪Food and Beverage Industry:

In food and beverage production, chemical dosing systems are used to add flavorings, pigments, preservatives and other food additives to ensure the flavor, appearance and shelf life of the product.

▪Water treatment industry:

Water treatment plants use chemical dosing unit to add chemicals such as disinfectants, purifiers and conditioners to purify and treat water supplies and ensure the quality of drinking water.

▪Chemical Production:

The chemical industry uses dosing systems to add raw chemicals to reaction tanks to produce a variety of chemical products such as polymers, pigments, dyes, and additives.

▪Oil and natural gas industry: In the process of oil field mining and refining, chemical dosing systems are used to add treatment agents, preservatives and desulfurizers to improve oil quality and production efficiency.

▪Pulp and Paper Industry: This industry uses dosing equipment to add chemicals to improve the quality of the pulp, the efficiency of the bleaching process and the properties of the final paper.

▪Chemical waste treatment: In chemical waste treatment, dosing systems are used to add neutralizers and other treatment agents to process hazardous waste into a safer form to comply with environmental regulations.

▪Metallurgical industry: In the metallurgical industry, chemical dosing systems are used to add fluxes, desulfurizers and alloying elements to improve the metal refining and casting process.

▪Sewage treatment: Sewage treatment plants use dosing systems to add coagulants, flocculants and disinfectants to remove suspended solids and harmful microorganisms in sewage.

▪Energy Production: In energy production, such as nuclear and solar power, chemical dosing systems are used to process cooling water and coolant to maintain equipment performance and safety.

These are just some examples, chemical dosing systems play an important role in multiple industrial sectors, helping to improve production efficiency, quality control and environmental protection.
