Double-chamber Fine Filter Overview: The efficient double-chamber fine filter designed by our factory has broken the limit of traditional concrete filter chamber,Website:http://www.dhpetrotools.com, which completely adopts steel structure to improve the treatment capacity of unit area and to make it convenient to operate and manage. The products of our factory is constantly improved based on the successful operation experience at various projects over the years and the feedback and suggestions of various users, combining to the features of traditional filter chamber and years of production experience of our factory. Therefore, it is improved day by day in its application and performance.  The updating and perfecting of the equipment gave wider treating capacity and application scope, besides, it is practical to design and manufacture steel structure filter of other specifications and various specifications with above two chambers based on different requirements of users. Double-chamber fine filter has many advantages of high filter precision, sound acid-base resistance property, strong mechanical strength, sound heat stability, long service life and good clean condition, which is especially suitable for precise filtration and separation of medium of strong acid, strong base, high temperature and high pressure.  Operating principle:Full automatic double-chamber fine filter of DHL-3000/S/G is a kind of filter equipment designed based on deep and surface filtration principles, which can eliminated the petroleum matter and suspended solid from the sewage produced by the oil field with the filter medium of superior emery and strictly control the particle size in water filtered with the filter element of inferior PE sintered pipe. The water would flow from the top to bottom through two stages during filtration. The water would flow from the bottom to the top to make the dirt come off the filter element and discharged from the backwash opening during backwash.  Double-chamber filter includes vertical cylindrical tank with upper clapboard and lower clapboard inside the tank body, the upper part of the upper clapboard is the upper chamber for filter medium, and the lower part of the lower clapboard is the lower chamber with PE sintered pipe installed, the space between upper clapboard and lower clapboard is water box, there is shell reinforcing plate for circumferential connection of upper clapboard and lower clapboard, and supporting device shall be set between the upper clapboard and lower clapboard. The new and practical product has long service life, it can control suspended particle size through pre-filtration of the first stage and refined filtration of the second stage with the features of high filter precision, no short flow during filtration, corrosion resistance, abrasion resistance, heat resistance, long service life, strong adsorption capacity, which can achieve the mixed backwash of water and gas.  Scope of application: It is widely used for underground water injection, process water filtration of industries of metallurgy, mining, machinery, electronics, electroplating, chemical engineering, textile, food and beverage and the deep treatment of greasy dirt water in backward stage.  Main features:  1. Procedural operation, full automatic backwash, simple operation.  2. The filter element is applicable for the deep treatment of greasy dirt water in backward stage with complete backwash and no blocking.  3. Two control modes of automatic control mode and quantitative control mode.  4. It is configured with efficient antifouling cleaning device with low water consumption for cleaning.  5. The operation of the device is flexible, and the device is applicable for the operation of single set and parallel and cascade operation.Technical parameters:ModelFormatsDHDL-2600DHDL-3000Filtered water volume (m3/h)150210Filter area ((m2)5.317.07Filter speed (m/h)5~20Diameter of filter medium D (mm)0.5~1.0Water suspended solid before filtration (turbidity)≤20mg/L(FTU)Water suspended solid after filtration (turbidity)≤3.0mg/L(FTU)Sewage intercepting capacity6-10kg/m3Resistance loss of filtrationInitial pressure loss is about 0.02MPa;The pressure difference of water inlet and outlet during filter failure is 0.05-0.10MPaWorking pressure0.05~0.6MPaWorking temperature ℃5~40 (it can be customized for special requirementsWater pressure for washing0.1MPaWater strength for washing10-12L/S.m2Air pressure for washing0.05-0.1MPaAir strength for washing60L/S.m2
