Kaifeng Power Generation Branch Physical and Chemical Dust Removal Project

In recent years, with the rapid economic development, the number of metallurgical steelmaking electric furnaces and boilers using raw coal as fuel has increased significantly. The atmospheric pollutants emitted by these furnaces and kilns cause great harm to the surrounding environment. Therefore, technologies to remove particulate matter from dust-laden gases to reduce their emission into the atmosphere have become increasingly important. Essential supporting equipment for self-cleaning filters in industrial atomization dust removal projects The spray dust suppression system, also known as the water mist dust suppression system or water curtain dust suppression system, is mainly aimed at places such as coal yards, thermal power plants, steel mines, coking plants, material yards, and docks where excessive dust causes environmental pollution and where large amounts of water spraying like spray guns are not needed. It uses nozzles of different shapes and atomization angles to atomize water, which then coagulates with dust and settles, achieving the purpose of eliminating dust and purifying the environment. The entire spray system consists of a water system and a control system. The water system includes water sources, pipelines, valves, filters, and dust removal atomizing nozzles; the control system consists of solenoid valves, sensors, controllers, etc. The spray dust suppression system features easy operation, maintenance-free, fast, and flexible characteristics, and has achieved good dust reduction effects in practice. In the atomization dust suppression system, water needs to be converted into gas, and the source water plays a key role in the normal use of the atomization system. The atomizing nozzle is generally about 0.5mm or finer. If there are solid impurities and suspended substances in the raw water, they will gradually clog the nozzle, resulting in an unclear atomization effect. The self-cleaning filter was developed for use in the system. The self-cleaning filter is a device that does not require manual maintenance, can automatically filter and automatically discharge solid impurities and suspended substances in the atomizing raw water, greatly reducing nozzle clogging. It is now widely promoted in automation engineering projects. Fumide self-cleaning filters are long-term suppliers in professional automation engineering projects, capable of providing professional and precise selection to ensure the effectiveness of the equipment and to fulfill the important role that self-cleaning filters should play.

 Dirty water enters from the filter inlet, first passing through the coarse filter screen to remove larger particles, then reaching the fine filter screen. During filtration, the fine filter screen gradually accumulates dirt and impurities from the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference forms on the inside and outside of the fine filter screen. When the pressure difference of the self-cleaning filter reaches the preset value, a switch signal is sent to the control box PLC system to start a cleaning cycle. Cleaning process: The cleaning mechanism of the fully automatic negative pressure suction filter is a stainless steel spiral up-and-down moving suction scanner. It is hollow in structure, with several suction nozzles vertically distributed at certain distances along its axis. The inside of the suction scanner communicates with the 3” drain valve. When the drain valve opens, the pressure difference between the internal water pressure of the filter and the external atmospheric pressure generates strong suction at each suction nozzle. At each suction nozzle, water flows rapidly from outside to inside in reverse, washing impurities attached to the inner wall of the filter screen into the suction nozzle, through the hollow shaft of the suction scanner, then discharged through the drain valve, completing the cleaning process which takes about 30-60 seconds. At this time, the pressure difference returns to normal, the cleaning process ends, and filtration resumes. During cleaning, the system continues to flow.
