Some clean circulating water is forced to flow from the outside of the v-bank filter element into the inside of the filter element, and the impurity particles adsorbed on the inner wall of the filter element flow into the steam plate with the water and are discharged from the sewage valve. The working principle of the filter is: when the filter works, the water to be filtered enters through the nozzle, flows through the filter screen, and enters the pipeline required by the user through the outlet for process circulation. The particulate impurities in the water are intercepted by the filter screen. With this continuous cycle, more and more particles are intercepted and the filtration speed is slower and slower.
The inlet sewage is still entering, and the filter hole will become smaller and smaller, resulting in the pressure difference between the inlet and outlet. When the difference reaches the set value, the differential pressure transmitter sends an electrical signal to the controller. When the v-bank filter works, the turbid liquid enters the lower chamber of the filter through the inlet and enters the inner chamber of the filter element through the diaphragm hole. Impurities larger than the filter element groove are intercepted, and the purified liquid enters the upper chamber through the groove and is finally discharged from the outlet. The filter adopts high-strength wedge filter, which automatically cleans the filter elements through differential pressure control and timing control. When impurities accumulate on the surface of the filter element, the pressure difference between the inlet and outlet increases to the set value, or the timer reaches a predetermined time, the electric control box sends a signal to drive the backwash mechanism.
When the backwash pumping hole is directly aligned with the inlet of the filter element, the sewage valve is opened. At this time, the system releases pressure and discharges water, and a negative pressure area appears between the suction cup and the filter element, and its relative pressure is lower than the water pressure outside the filter element. The specially designed filter screen produces jet effect inside the filter element, and any impurities will be washed away from the smooth inner wall. When the pressure difference between the inlet and outlet of the v-bank filter returns to normal or the timer setting time ends. In the whole process, the flow of materials is not cut off, the backwashing water consumption is less, and the continuous and automatic production is realized. Filters are widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power and urban water supply. Such as industrial wastewater, circulating water filtration, emulsion regeneration, waste oil filtration treatment, continuous casting water system and blast furnace water system in metallurgical industry, high-pressure water descaling system for hot rolling.
The LENGE system is based on the standard disc filter unit and is designed in a modular way. Users can choose and choose according to their needs, which is flexible and variable. The system is compact and covers a small area, which can be installed by using corner space Efficient backwashing and accurate filtration. The disc filter with special structure is accurate and sensitive, which strictly ensures that only particles with particle size less than the requirements can enter. It is the most effective filtration system. Users can select v-bank filter discs with different filtration accuracy and operation flow according to water requirements. The high-speed and thorough backwashing can be completed in only 15 ~ 20 seconds. The backwashing water consumption is lower than 0.5% of the filtered water.
LENGE is a company specializing in the production of filters. it is not only a supplier of v-bank filter, but also a manufacturer of v-bank filter. if you need it, please contact us.It runs automatically and discharges water continuously. Long service life. The high-tech plastic filter element is firm, wear-free and corrosion-free. It has been verified by many parties that the filtering and backwashing effect will not weaken with time; The operation is reliable and the maintenance is simple. The filter system has pressure gauges at the main inlet and outlet pipes and the inlet and outlet of each filter unit, so as to be timely and accurate in case of failure
