Wet scrubber automatic dosing device

Automatic chemical dosing tank

Share this post :

An automatic chemical dosing tank is a specialized system designed to automatically and precisely dose specific chemicals into a process, system, or water treatment application without manual intervention. These systems are commonly used in various industrial and commercial settings where accuracy, consistency, and efficiency in chemical dosing are crucial.

Chemical dosing tanks

Features and components of an automatic chemical dosing tank:

  1. Tank or Reservoir: The core component is a chemical storage tank or reservoir, typically made of materials compatible with the chemicals being dosed. The tank’s capacity can vary depending on the specific application and required chemical volume.
  2. Chemical Injection Pump: An automatic dosing system is equipped with a chemical injection pump, which is responsible for delivering the precise amount of chemical into the process or system. These pumps are often positive displacement pumps, diaphragm pumps, or peristaltic pumps, selected based on the characteristics of the chemical.
  3. Control System: An automated control system is at the heart of the dosing tank setup. It includes sensors, controllers, and programming that monitor the process conditions and adjust the chemical dosing rate accordingly. Common sensors may include pH sensors, turbidity sensors, flow meters, and conductivity sensors, depending on the application.
  4. Programming and Setpoints: The control system is programmed with setpoints and dosing schedules to ensure the correct amount of chemical is delivered at the right time. It can be set up to respond to changes in process conditions in real-time.
  5. Safety Features: Automatic dosing systems often include safety features such as leak detection, overpressure protection, and alarms to prevent accidents and chemical spills.
  6. Mixing and Agitation: Some automatic dosing systems include mixing or agitation mechanisms to ensure proper dispersion of the dosed chemical into the process or solution.
  7. Remote Monitoring and Control: Many modern automatic dosing systems can be remotely monitored and controlled through digital interfaces and communication networks, allowing operators to make adjustments and receive notifications remotely.
  8. Calibration and Maintenance: Regular calibration and maintenance of the system components, including the pumps and sensors, are essential to ensure accurate dosing and prevent equipment failures.
  9. Chemical Compatibility: It is crucial to choose materials and components that are compatible with the specific chemicals being dosed to prevent corrosion and contamination.

Automatic chemical dosing tanks find applications in various industries, including water and wastewater treatment, chemical manufacturing, agriculture, food and beverage processing, and more. They are valued for their ability to maintain precise chemical concentrations, reduce labor costs, improve process efficiency, and enhance the safety of chemical handling and dosing operations.

Components of automatic chemical dosing tank

The automatic chemical dosing tank is a device used for precise dosing of chemicals. It is usually used in industry, water treatment, pharmaceutical, chemical and other fields. The following are the main components of an automatic chemical dosing pump:

  • Pump head: The pump head is the core component of the automatic chemical dosing pump and is responsible for delivering chemicals from the storage container to the system. The pump head usually includes mechanical components such as a piston, diaphragm, gear or screw, and is customized according to different types of pumps.
  • Motor: The motor provides energy to drive the pump head to perform the suction and discharge operations of chemicals. The type and power of the motor depends on the needs of the application and the design of the pump.
  • Control system: The control system monitors and regulates the dosing flow to ensure accurate dosing. It typically includes controllers, sensors and programming equipment that can be programmed as needed to achieve automation.
  • Liquid Storage Tanks: Chemicals are usually stored in specific containers, which can be liquid storage tanks, barrels, PP water tanks, or other containers, depending on the size and requirements of the dosing system.
  • Suction and Delivery Lines: These lines connect the pump head to the reservoir, allowing chemicals to be sucked in and delivered to the target location. These pipes are often corrosion-resistant to accommodate different types of chemicals.
  • Filter: In order to prevent impurities from entering the pump head or dosing system, a filter is usually installed on the suction line to ensure the purity and reliability of dosing.
  • PH monitor meter: Monitors the PH value of the washing liquid in real time. When the PH value is lower or higher than the set value, the automatic dosing system is turned on.
  • Control Valve: Sometimes, a dosing system may require a control valve to regulate flow or stop dosing when needed.
  • Control box: Integrate all operating system data for centralized control, equipment power supply, abnormal alarm, etc.
Dosing Pumps

The design and component selection of automated chemical dosing pumps depends on the specific application and chemicals to ensure the accuracy, reliability and safety of the dosing process. These systems are widely used in a variety of industries to precisely control the addition of chemicals to meet the specific requirements of a production or processing process.
