Coke Oven Gas FilterThe coke oven gas filter is welded of stainless steel with special process design and can be installed side by side. It achieves filtration precision of 1–10 microns, featuring corrosion resistance and easy maintenance. Please feel free to contact us if you need more detailed information or relevant documents about filter elements for coke oven gas power plants.Installation PrecautionsThe gas filter shall generally be installed upstream of the pressure regulator and mounted strictly in accordance with the gas flow direction marked on the unit.The filter screen is washable. Ensure the cover can be easily opened for cleaning and inspection during installation.The filter can be mounted on horizontal or vertical pipelines, but never on unstable foundations.Before maintenance, fully evacuate all gas inside the filter, remove the screen for cleaning, air-dry it naturally, then reinstall.Warm RemindersConduct tightness test after installation is completed.Avoid excessive instantaneous gas flow during gas supply startup.Parameters required for model selection: medium, operating pressure and nominal diameter.Henan Yongxin Technology Co., Ltd. is a manufacturer specializing in filter elements and filters for construction machinery, coal, metallurgy, electric power, chemical, electronics, food and other industries.

Magnetic FilterThe magnetic filter is assembled with multiple strong magnetic rods made of permanent magnet materials through special magnetic circuit design. During the transportation of liquid slurry, ferrous fine particles ranging from 0.5 to 60 microns in the slurry will be adsorbed on the magnetic rods. It thoroughly removes iron impurities from the slurry to purify materials, guarantee product quality, production safety and stable operation of downstream equipment.Product Features■ Magnetic field strength reaches 12000GS with a service life of over 10 years; ■ Optimized magnetic circuit design and high-gradient multi-stage filtration ensure full contact between fluid and magnetic rods for excellent iron removal performance; ■ Zero energy consumption during operation, no consumables or moving parts, quick installation and easy cleaning; ■ Housing available in SS304 or SS316L stainless steel.Number of Magnetic Rods5 pcs7 pcs9 pcsHousing MaterialSS304, SS316L Stainless SteelInlet & Outlet DiameterDN25-100, flange, thread, clamp quick-open connectionWorking Pressure1.0MPa, 1.6MPaSurface TreatmentMat sandblasting, mirror polishingRemarks1. Thermal insulation jacket design is optional to maintain or raise liquid temperature, prevent liquid solidification and meet temperature requirements of production lines;2. Magnetic rods can be equipped with stainless steel jacket for easy cleaning of adsorbed impurities.Typical ApplicationsMagnetic filters are suitable for removing iron powder and other magnetic impurities mixed in high-concentration liquids, including food products (syrup, jam, fruit juice, edible oil, chocolate) and chemicals (paint, lubricating oil, cutting fluid, dye, industrial syrup, pulp, salt water).

Automatic Backwash FilterThe automatic backwash filter consists of housing, filter cartridge assembly, backwash rotating arm, transmission shaft, motor reducer, position limit switch, control cabinet, electric/pneumatic valves, differential pressure controller and other components.The medium to be filtered flows from inside to outside through the wedge wire filter cartridges, and solid particles are trapped on the inner surface of cartridges. As contaminants accumulate, the differential pressure between the dirty side and clean side of the filter rises. Automatic backwashing will be triggered once the differential pressure reaches the preset value (or it can be controlled by time cycles).During backwashing, the motor rotates the backwash arm to the cartridge to be cleaned, cutting off raw liquid flow to this cartridge. The backwash valve opens, and the pressure difference between the filtrate side and backwash pipeline reverses a portion of clean filtrate into the target cartridge. Contaminant particles accumulated on the cartridge inner wall are stripped and flushed through the rotating arm into the backwash pipeline. Once the backwash duration for one cartridge expires, the backwash valve closes immediately. All cartridges are cleaned sequentially in this way, and the backwash cycle finishes after all cartridges are cleaned.Advantages of the FilterOnline cleaning without shutdown, programmable automatic control, large filtration area and safe operation.Main Specification & Parameter TableModel SeriesYXZBInlet & Outlet Nominal DiameterDN50-DN500Flange Standard for Inlet & OutletHG/T20592-2009, HG/T20615-2009Flow Rate20–8000 m³/hFiltration Precision25–1000 μmDesign Pressure0.6 MPa / 1.0 MPa / 1.6 MPa / 2.5 MPa / 4.0 MPaBackwash Trigger Differential Pressure0.05 MPa–0.07 MPaRequired Pressure for Backwashing≥0.2 MPaControl ModeTimer / Manual / Differential PressureFilter Element Type & MaterialWedge Wire, 5-Layer Sintered Mesh, Powder Sintered Cartridge (304 / 316L)Housing MaterialC.S (Carbon Steel) / SS304 / SS316LHousing Seal MaterialNBR, FKM

YXFC Multi-Cartridge Automatic Backwash FilterBrief IntroductionThe YXFC multi-cartridge automatic backwash filter can filter raw water and automatically clean and drain filter cartridges without interrupting the water supply system during cleaning. Compared with conventional filters, it features high automation, large treatment capacity, self-cleaning & self-draining function, uninterrupted water supply and wide applicability.Working PrincipleFiltration ProcessLiquid flows into the equipment inlet and passes from the inner side to outer side of cartridges, with solid impurities trapped on the smooth inner surface of cartridges. As contaminants accumulate, the differential pressure between the inner and outer walls of cartridges rises. Once the preset differential pressure is reached, the differential pressure switch sends a signal to activate the backwash sequence. Alternatively, the controller triggers backwashing automatically when the continuous running time hits the preset value on the built-in timer.Automatic Backwashing ProcessOnce the preset differential pressure or running time is reached, the backwash signal is transmitted and the pneumatic blowdown valve opens. The filter’s reduction motor rotates the central transmission shaft to drive the rotary backwash arm. When the arm aligns with the bottom of one cartridge, the inner cavity of this cartridge connects to the blowdown pipeline, cutting off the raw liquid inlet and linking the cartridge interior to the low-pressure blowdown zone. A backwash differential pressure forms between the cartridge’s outer clean side and inner dirty side, driving clean filtrate to reverse-flow from outside to inside the cartridge and flush contaminants attached to the inner wall into the blowdown pipeline. The backwash duration for each cartridge is generally 1.5 seconds. The rotary arm sequentially cleans every cartridge as it rotates. After one full rotation back to the home position, one complete backwash cycle finishes. Once the inlet-outlet differential pressure drops back to the initial level after one or multiple cycles, the filter resumes normal filtration mode.Technical Features & AdvantagesAutomatic continuous online filtration with uninterrupted flow during backwashing, cutting downtime and maintenance costs;Large total filtration area and low surface flow velocity reduce backwash frequency to save backwash water and operating costs;Adopts V-type filter elements with precise slits, high mechanical strength and long service life;Pulse backwashing design: blowdown valve opens only after aligning with target filter elements, delivering powerful, efficient and quick backwashing with low water consumption.Typical Application FieldsApplicable IndustriesWater treatment, steel, papermaking, mining, petrochemical, precision metal processing, municipal engineering, etc.Applicable LiquidsGroundwater, seawater, lake water, reservoir water, circulating cooling water, chilled water, spray water, heat exchange water, sealing water, bearing cooling water, oilfield injection water, process circulating water, machining coolant, cleaning water and more.
