Detailed structure

Dr.Air DS-13L diesel exhaust treatment machine is a complex system, designed to remove pollutants in diesel exhaust before releasing them into the environment. Below is the detailed structure of the machine:

1. Body

• Housing: Usually made of stainless steel or composite materials, ensuring durability and corrosion resistance in marine environments.
• Support frame: Provides stability to the entire system.

2. Fan system

• Industrial fans: Create negative pressure to draw exhaust gas from the engine into the treatment system.
• Motor: Provides power for the fan to operate.

3. Filter chamber

• Primary filter: Removes large dust particles and debris.
• DPF (Diesel Particulate Filter): Traps ultra-fine dust particles and soot.
• DOC (Diesel Oxidation Catalyst) Filter: Converts toxic gases such as CO, HC into CO2 and H2O.

4. Control system

• Controller: Controls fan speed, system operating temperature, and other parameters.
• Sensors: Measure parameters such as pressure, temperature, exhaust gas flow to adjust the treatment process.
• Display screen: Displays the machine’s operating parameters, helping users easily monitor and maintain.

5. Piping system

• Intake pipe: Conducts exhaust gases from the engine into the system.
• Exhaust pipe: Releases clean air into the environment.

6. Other parts

• Drain valve: Helps drain dirt accumulated in the DPF filter.
• Pressure Sensor: Measures back pressure across the DPF filter to determine when regeneration is needed.
• Cooling system: Helps cool engine components, especially the DPF filter during regeneration.

How does Dr.Air DS-13L drilling rig diesel engine exhaust gas treatment machine treat exhaust gas?

DS-13L diesel engine exhaust treatment machine is composed of 2 filter parts: DOC (oxidation catalyst) and DPF (dust filter). The combination of these 2 technologies brings comprehensive efficiency in treating dust and toxic gas compounds.

The operating process of the equipment is as follows: When the DS-13L diesel exhaust treatment machine is running, the exhaust gas of the diesel engine passes through the honeycomb catalyst and the particulate filter. At that time, the polluting gases (HC, CO, PM, NOx) are rapidly oxidized under the effect of the catalyst coating on the surface of the carrier (urea solution), to transform into CO ₂  , H ₂ O and other substances that are more environmentally friendly.

Things to note when using diesel exhaust treatment equipment

When using diesel engine exhaust treatment equipment, the following points should be noted to ensure efficiency and safety:

• Follow the operating instructions : Read and operate the equipment according to the manufacturer’s instructions, and perform regular maintenance as recommended.
• Use fuel and fluids correctly : Use only standard diesel fuel and genuine urea (AdBlue) fluid for the SCR system, undiluted.
• Periodic Inspection : Regularly check components such as filters, sensors, and solenoid valves; replace damaged or expired parts.
• Cleaning and maintenance : Clean filters periodically to prevent clogging and replace urea solution when levels are low.
• Safety Precautions : Avoid contact of urea solution with eyes, skin or digestive tract, and keep away from heat or sparks when working with the system.
• Compliance with legal regulations : Ensure equipment operates according to emission standards and conduct periodic inspections as required.

These precautions help ensure the equipment operates efficiently, safely and complies with environmental regulations.
