For a long time, the use of water-based paint repair scratches, paper boxes are the primary filter must be done by professionals. In addition, many people are aware of the current high efficiency filter yet avoid the "water" approach. Above contributed to the implementation of the law on environmental protection in the body repair shop. One key factor is the air purifier: should be emphasized! Air is one of the body shop in the main energy carrier. It is generated by the compressor, and then is fed into the supply line. In the meantime, lubricating oil and other pollutants have been brought to the user. They usually do not have an impact on pneumatic tools (such as a screwdriver or a glove box polished, etc.). However, for high-quality paint job, the residual oil and condensate, even a very small amount of residual oil or condensate will cause coating defects. They usually produce very small pits and other phenomena, which inevitably lead to complaints from the coating quality. At this time, we must rework, wasted a huge cost. Not only traditional solvent coatings cause of these problems, a water-soluble coatings also have the above problems. Now, with multiple si systems non-woven filter section filters filter system (for example: SATA0 / 444) to become qualified auto repair shop essential devices. They can be separated from the desired air pollutants out (such as: residual oil, condensate and suspended matter, etc.), level of less than 0.01 micron filter. When extremely fine oil vapor into the gas stream, usually si systems the smell, which shows that these devices have reached the limit. These tiny oil residue may cause trouble. In this case, add a carbon filter, you can solve the problem. You must use the media (e.g., using gas breathing masks), make sure that the user does not come into contact si systems with the oil residue, even a very small amount of oil residue. Activated carbon filters may also be used to purify the air spraying, there is no limitation to this. They can be used absolutely reliable manner all kinds of oils and the residue isolated from the desired air. After saturation of activated carbon filter cartridge must be replaced immediately. The modular structure of the activated carbon filter can be easily connected to any existing and past SATA filter. There is a small bar in front of the display glass protection. It can change color, sustained level of performance and service life of the display on the SATA activated carbon filter 0/464. This enables easy maintenance, to ensure safety, so as not to miss the appropriate filter cartridge replacement. Activated carbon filtration devices work: charcoal work process can be simply summed up as: mining water: raw water inflow from above charcoal tower tank, the activated carbon filter under the outlet means to obtain water quality to remove impurities, odors and the like. backwashing: the purpose of eviction sediments above the charcoal. After a period of filtration, activated carbon si systems is deposited over the number of impurities is discharged and removed. Shen whole: When backwashing the activated carbon will go up, a backwash valve is closed after completion of all activated carbon sink due to gravity. Wash : When backwashing fear of activated carbon impurities attached below, with n-wash to wash water harvesting time in order to avoid water pollution. Activated carbon is to work with the above five steps cycle operation. However, there are certain times on each step. Pressure si systems activated carbon si systems filter design parameters: The main design parameters of pressure-type activated carbon filters include: filtration rate (m / h) or hydraulic si systems load (m3 / m3 min), activated carbon layer height and backwash strength. An on-site charcoal column si systems tests should be carried out to verify the relevant design parameters according to the raw water quality. If there is no field test conditions on water quality and no special requirements, surge can be filtration rate of 3 ~ 10m / h, the activated carbon layer height 2 ~ 3m, backwashing intensity 4 ~ 12L / s m2. From the conclusions previously published charcoal si systems column test reports, you can analyze some basic laws for design reference. First, reduce the filtration rate (ie reducing the hydraulic load one can increase the utilization of carbon, carbon si systems regeneration cycle extended, but under conditions of constant water production, reduce filtration rate would increase the area of development, si systems namely the increase did not filter in diameter, si systems increasing the amount of time with charcoal, requires a larger area of the room in the filter efficiency. Similarly, the increase in the thickness of the carbon layer (multi-column series is also equivalent to an increase of carbon layer thickness), si systems can improve the utilization of the carbon layer, and can improve the safety of the water sex, but it also increases the filter once with carbon content, the higher the height requirements for the equipment room. The actual design, under the premise to ensure water quality, should be considered the engine room conditions (including area, height), carbon utilization , the technical and economic factors that change carbon cycle, determine the design parameters. si systems In addition, activated carbon adsorption to remove organic matter is a process, not like sand filtration as a mechanical closure process. backwashing si systems sand column can be removed and the filter surface si systems cracks in the impurities, but can not remove the activated carbon adsorption of organic matter, but older than the change in the density of carbon particles, would have been saturated with carbon particles adsorbed to move from the upper to the lower, the impact of the treatment effect. Therefore, before entering the activated si systems carbon filter, you should try to filter machinery si systems impurities; si systems the charcoal filter during backwash as little as possible when necessary, replace them with surface water.
