Electric Tar CatcherThe Correct Usage Process:
Preparation For Starting
Check The Equipment: Ensure That The Electric Tar Precipitator Body And Auxiliary Equipment Are Not Damaged, All Components Are Securely Connected, And There Is No Leakage. Check If The Electrode Wires Are Installed Correctly And Neatly, And If The Distance Between Them And The Sedimentation Electrode Meets The Requirements.
Electrical System Inspection: Check Whether The Various Parameter Settings Of The High-voltage Power Supply Device Are Correct, Whether The Grounding System Is In Good Condition, And Whether The Insulation Resistance Meets The Specified Requirements. Test The Functionality Of The Control Circuit And Protection Circuit To Ensure Timely Issuance Of Alarm Signals And Implementation Of Protective Measures During Equipment Operation.
Pipeline System Inspection: Check Whether The Inlet And Outlet Pipelines Are Unobstructed, Whether The Valves Are Flexible And Reliable, And Whether They Are In The Correct Open Or Closed Position. Ensure That The Tar Venting Pipeline, Steam Blowing Pipeline, And Other Auxiliary Pipelines Are Connected Correctly And Unobstructed.
Gas Replacement: Before Starting The Electric Tar Precipitator, Inert Gases Such As Nitrogen Or Steam Must Be Used To Replace The Equipment To Eliminate Internal Air And Flammable Gases, Preventing The Formation Of Explosive Mixtures. After Replacement, The Oxygen Content In The Gas Inside The Analysis Equipment Should Be Lower Than The Specified Value (generally Not Exceeding 1%).
Adding Insulating Oil: For Electric Tar Catchers That Use Insulating Oil As The Insulating Medium, It Is Necessary To Check Whether The Oil Level And Quality Of The Insulating Oil Meet The Requirements. The Oil Level Should Be Within The Specified Range, And The Oil Quality Should Be Clear And Transparent, Free Of Impurities, Moisture, And Odors. If The Oil Quality Does Not Meet The Requirements, It Should Be Replaced Or Filtered In A Timely Manner.
Turn On The Chilled Water System: If The Electric Tar Precipitator Is Equipped With A Refrigeration Device, The Cooling Water System Should Be Turned On First To Ensure That The Chilled Water Pipeline Is Unobstructed, And The Chilled Water Flow And Pressure Meet The Equipment Operation Requirements. By Adjusting The Flow Rate Of Chilled Water, The Operating Temperature Of The Electric Tar Catcher Is Controlled Within The Specified Range.
Start And Run
Start The High-voltage Power Supply: After Confirming That The Above Preparations Are Completed And Correct, Close The Switch Of The High-voltage Power Supply, Gradually Increase The Voltage, And Make The Electric Tar Catcher Reach The Normal Working Voltage. During The Boosting Process, It Is Necessary To Closely Observe The Changes In Voltage And Current, As Well As The Operating Status Of The Equipment. If Abnormal Fluctuations In Voltage And Current Are Found, Or If The Equipment Discharges Or Makes Abnormal Noises, The Boosting Should Be Stopped Immediately, The Cause Should Be Identified And The Fault Should Be Eliminated Before Continuing The Boosting.
Observing Operating Parameters: During The Operation Of The Equipment, It Is Necessary To Continuously Monitor Operating Parameters Such As Voltage, Current, Temperature, And Pressure To Ensure That They Are Within The Specified Range. Generally Speaking, The Working Voltage Of An Electric Tar Catcher Is Around 30-40kV, And The Current Varies Depending On The Processing Gas Volume And Tar Content, Usually Ranging From Tens Of Milliamps To Hundreds Of Milliamps. At The Same Time, Attention Should Be Paid To Observing The Temperature And Pressure Changes Of The Inlet And Outlet Gases, As Well As The Tar Emissions.
Regular Tar Discharge: Conduct Regular Tar Discharge Operations Based On The Accumulation Of Tar In The Electric Tar Catcher. When Discharging Tar, The Valve On The Tar Discharge Pipe Should Be Closed First, And Then The Tar Discharge Valve Should Be Slowly Opened To Discharge The Tar Into The Tar Collection Container. During The Discharge Process, Attention Should Be Paid To Observing The Flow Rate And Status Of Tar To Prevent It From Being Discharged Too Quickly Or Blocking The Pipeline. After Discharging Tar, Promptly Close The Tar Discharge Valve And Open The Valve On The Tar Discharge Pipe To Restore Normal Operation.
Patrol Inspection: Operators Should Conduct Regular Patrol Inspections Of The Electric Tar Precipitator To Check The Operation Status Of The Equipment, Whether There Are Leaks In The Pipeline Connection Parts, Whether The Valves Are Normal, And Whether The Electrical Equipment Is Overheated And Other Abnormal Conditions. At The Same Time, It Is Necessary To Check The Operation Of Auxiliary Equipment Such As The Cooling System And Lubrication System To Ensure Their Normal Functioning. If Any Problems Are Found, They Should Be Promptly Recorded And Corresponding Measures Should Be Taken To Handle Them.
Parking And Maintenance
Normal Parking: First, Gradually Reduce The Voltage Of The High-voltage Power Supply Until The Power Is Turned Off. Then Close The Valves On The Inlet And Outlet Pipelines And Cut Off The Gas Source. After The Gas Inside The Equipment Is Completely Discharged, Blow The Equipment With Nitrogen Or Steam To Remove Residual Gas And Tar. The Blowing Time Is Generally Not Less Than 30 Minutes. Finally, Turn Off The Power To The Cooling Water System And Other Auxiliary Equipment.
Emergency Stop: In Case Of Sudden Power Outage, Equipment Failure, Gas Leakage Or Other Emergency Situations During Equipment Operation, The Emergency Stop Button Should Be Immediately Pressed To Cut Off The High-voltage Power Supply, And The Inlet And Outlet Valves Should Be Quickly Closed To Stop Gas From Entering The Electric Tar Precipitator. At The Same Time, Activate The Corresponding Safety Protection Devices, Such As Vent Valves, Nitrogen Purging Devices, Etc., To Ensure The Safety Of Equipment And Personnel. After Emergency Parking, The Cause Should Be Promptly Identified, The Fault Should Be Eliminated, And After Inspection And Confirmation, The Equipment Can Be Restarted.
Regular Maintenance: Regularly Maintain The Electric Tar Catcher, Including Checking The Wear Of The Electrode Wire. If There Is Wear Or Deformation, It Should Be Replaced Or Adjusted In A Timely Manner; Clean The Sedimentation Electrode And Corona Electrode To Remove Tar And Dust Adhering To Them, In Order To Maintain Their Good Conductivity And Capture Effect; Check The Insulation Performance Of Insulation Components, Such As Insulation Porcelain Bottles, Insulation Sleeves, Etc. If There Is Any Damage Or Aging, They Should Be Replaced In A Timely Manner; Perform Anti-corrosion Treatment On The Casing, Pipelines, Etc. Of The Equipment To Prevent Corrosion From Affecting The Service Life Of The Equipment.
