Candle filter builds a barrier to “water resourcesâ€
When the candle filter starts to filter, it does not use the large flow of zui and uses 80% flow filter, which makes the filter layer more uniform and the pressure difference rises more slowly. In addition, there are some advantages when using the candle filter. According to the system configuration, the direct supply mode can be realized for the package, which can greatly reduce the cost of washing the tank and reduce the water consumption. The candle filter combines a plurality of porous filter elements in a closed container, and filters the filter cloth (or other filter medium) on the filter casing. When filtering, the slurry is sent into the filter by the pump, and the liquid in the slurry passes through. The filter medium enters the center of the porous filter element and is discharged to the clear liquid outlet. Before the candle filter does not form the filter cake, the discharged "clear liquid" is returned to the raw material slurry inlet and sent to the filter for circulation filtration until the candle filter The filter cake is formed, a signal is provided to control the clear liquid not to be recirculated, and the clear liquid is sent to the next process through the three-way valve for normal filtration.
The candle filter will become the protector of our water resources. We are questioning and questioning all around us. It is unreasonable to eat and wear. Can we break this situation for us? We look forward to the day when the results are revealed. Our water environment will return to the new era. One step at a time to treat the sewage, restore the original appearance of the sewage, so that sewage is no longer our nightmare.
Candle filter picture
The candle filter is usually cleaned once every 10-15 days, and the single cleaning time is longer and the water consumption is larger. The dirt is adsorbed in the fine pores of the diatomaceous earth, accelerating the proliferation of bacteria and viruses at a suitable temperature between the devices, which easily causes secondary pollution of the swimming pool water, which is not conducive to the health of the swimmer. The candle filter is used to maintain the equipment and prevent secondary pollution of the swimming pool water. It is required to backwash once a day. The backwashing time is short, and the cleaning can be completely completed with a small amount of water.
Since the candle filter can be refiltered to form a uniform cake layer, the filter cake can be conveniently washed by passing the washing liquid into the machine. If the filter cake is washed by the top spray method, the washing liquid can be greatly saved. If a dry filter cake is to be obtained, after filtration or after washing and filtering, normal temperature air, hot air or steam is introduced into the machine so that they can pass through the filter cake layer until the filter cake reaches the desired dryness. The pressure is relieved and the filter cake is unblowed from the bottom.
The candle filter is made of carbon steel and the lining is treated with anti-corrosion treatment, but the corrosion resistance is not good. The frame of the candle filter is made of engineering plastic with high strength, pressure resistance, corrosion resistance, no deformation and no pollution to water quality. The head is made of stainless steel and has a very long service life. The candle filter is a new type of diatomite filtration equipment from Zui. Due to its own advantages, it is gradually recognized by users at home and abroad, and it guarantees the excellent water quality in more and more projects.
After a period of normal filtration, when the filter cake on the porous wick reaches a certain thickness, a signal is provided to control the feed (stop), and then the residual liquid in the filter is drained, and a signal is provided to control the backflush for backflushing. After the filter cake is detached and backflushed for a certain period of time, the backflushing is stopped, a signal is provided to open the filter slag discharge port for slag discharge, and the slag discharge port is closed after the slag discharge is completed, and the initial state before the filtration is returned to prepare for the next round. filter. When the candle filter is used for liquid clarification, diatomaceous earth, activated carbon and other additives can be directly added to the slurry to make the filtration rate faster, the filtrate is more clarified, and the whole sealing operation is suitable for the filtration of general materials. It can be used for the flammable, explosive, toxic or highly toxic dangerous products and the filtration of delicious foods, biological products and medicines that are not allowed to be contaminated.
