The high-concentration wastewater needs to be filtered through a bag filter during the treatment. The high-concentration wastewater to be treated will directly enter the rate of the bag filter directly from the water inlet. The impurities in the water are deposited on the stainless steel filter. It can produce its pressure difference to some extent.
The bag filter will effectively monitor the pressure difference between its inlet and outlet through its pressure difference switch. When the pressure difference reaches its set value, the water supply control valve of the electronic controller and the drive motor signal will be directly induced. In the following actions, the motor drives the brush to rotate, and the filter element is cleaned. At the same time, the control valve is opened to drain. The entire cleaning process only lasts several tens of seconds. When the cleaning is completed, the control valve is closed, the motor stops rotating, and the system returns to its initial state. , start to enter the next filtration process.
After the bag filter is installed, the technician will carry out debugging during the operation. During the operation, the filter time and cleaning conversion time can be set to a certain extent. The water to be treated enters the body from the water inlet, and the bag filter The device starts working normally. When the preset cleaning time is reached, the electronic controller gives the hydraulic control valve and drives the motor signal.
Bag filters require constant inspection of the connection pipe for leaks and damage. When replacing the filter bag in the equipment, if you use a sewn filter bag, fold the filter bag so that the filter bag can be filtered. Place the filter bag so that the loop of the filter bag matches the neckline of the metal mesh.
Whether the inlet and outlet valves of the bag filter are closed tightly, check the pressure gauge and determine that the internal pressure is 0. At this time, the bag filter should be separated from the piping system. The emptying valve is opened until the remaining liquid in the bag filter is exhausted through the emptying valve and the lid is opened again.
