The high-concentration wastewater needs to be effectively filtered through its bag filter during the treatment process. Generally, the high-concentration wastewater to be treated will directly enter the rate of its equipment from the water inlet, and the bag filter water The impurities are deposited on the stainless steel filter, creating a pressure difference.
The bag filter monitors the pressure difference at the inlet of the bag by a pressure difference switch. When the pressure difference reaches the set value, the electric control valve of the electric controller drives the brush to rotate, and the filter element is cleaned. At the same time, the control valve is opened to discharge the pollutants. The entire cleaning process only lasts for tens of seconds. When the cleaning is completed, the control valve is closed and the motor stops rotating. The system returns to its initial state and begins to enter the next filtration process.
When the bag filter is installed, due to the technicians during the debugging process, the filter time and the cleaning conversion time are effectively set. The water to be treated of the device enters the body from the water inlet, and the bag filter starts. In normal operation, when the preset cleaning time is reached, the electronic controller gives the hydraulic control valve and drive motor signals.
The unit filter area of the bag filter system has a large flow rate, a small filtration resistance, and a high filtration efficiency. The filter function of a bag filter is equivalent to 5 to 10 times of the filter element, which can greatly reduce the cost; the design flow can meet the requirements of 1~500m3/h, and the cost is low. The
The use of bag filter is very extensive. It can be directly used for coarse, medium or fine filtration in the process of operation. Compared with the same filter effect, it can be compared with plate filter and filter cartridge. Filters and other equipment have the advantages of lower investment costs, long service life, and low cost of filtration.
