Causes and solutions for poor exhaust of kitchen electrostatic precipitator

Poor exhaust of restaurant fume duct will make the kitchen impossible to use normally. So what is the reason for poor exhaust of kitchen electrostatic precipitator? Is there any solution? Let me share the relevant reasons and solutions with you.

01 Improper installation:

The reason for poor exhaust is also caused by improper installation. If the entire project is not reasonably matched and installed, it is necessary to re-check the installation. It is recommended to ask professionals to install it.

02 Fan failure or failure to start:

If it was normal when used before, and suddenly the exhaust was not smooth, it may be that the fan was not turned on or the fan failed. In this case, observe whether the fan is turned on or damaged, and turn it on or replace it in time.

03 Damage to the check valve in the flue:

The check valve in the fume duct can effectively prevent the reflux of fume or water vapor. Once damaged, it will become an obstacle to the flue, the flue is blocked, and the fume cannot be discharged normally. When the fume is not discharged, you can check whether the one-way valve is damaged. If it is found to be damaged, you can reinstall it.

04 Too much grease is accumulated inside the electric field:

If the oil fume is discharged normally during installation, it cannot be discharged normally after a period of use. This indicates that too much oil has accumulated in the electric field of the kitchen electrostatic precipitator, resulting in increased wind resistance of the equipment. In this case, the equipment needs to be cleaned, dried after cleaning, and then reinstalled to solve the problem.

05 The built-in filter is not cleaned:

About 80% of the reasons for poor kitchen exhaust are due to the fact that the built-in filter of the kitchen electrostatic precipitator has not been cleaned for a long time, and the filter is blocked by oil. We can clean the built-in filter by disassembling the cleaning parts, soaking the cleaning parts, and brushing the dirty parts, so as to effectively ensure the purification effect.

06 Insufficient exhaust force caused by too long pipes:

The exhaust pipe has a certain wind resistance. For every additional 1 meter, the resistance will increase by 10Pa. If the fan and the kitchen electrostatic precipitator are reasonably matched, and the factor of pipe wind resistance is ignored, it will also cause unsmooth exhaust. In this case, it is necessary to replace a larger induced air volume fan or add an additional fan. ‍

07 The dust filter cotton is not installed correctly or has too much grease attached:

The dust filter cotton is generally installed at the air inlet. Check whether it is installed correctly. If there is too much grease in the filter cotton, it will increase the wind resistance and cause the smoke exhaust to be not smooth. In this case, the filter cotton needs to be replaced. Generally, the filter mesh has resistance. Be sure to use the standard filter mesh. Do not blindly thicken or replace it.

Today's content is shared here. In fact, more than 80% of the reasons for poor kitchen smoke exhaust are that the filter mesh of the electrostatic precipitator has not been cleaned for a long time, resulting in oil blockage. The flue is in a high temperature environment all year round, causing oil smoke deposition. If the oil smoke pipe and smoke hood are not cleaned in time, it will cause a fire.
