Q:How to choose the ear coffee bag?
2, the daily consumption of coffee is coffee with a variety of cooking utensils made out, which means coffee beans inside the fruit tree nuts, using proper baking, the taste is bitter taste.
Q:What is the dust removing filter material of the dust collector?
The filter bag filter area dust gas into the box, the vast majority of dust trapped in the outer surface of the filter bag, and clean gas through the filter into the filter bag, the purified gas through the filter opening into the box, then the air is discharged by the air outlet. The inside frame of the filter bag supports the bag, prevents the bag from collapsing and helps to clean and redistribute the dust.
Q:What materials are used for the air filter bag?
low resistance, large dust capacity, high filtration precision, convenient replacement, products are widely used in automotive electronic, pharmaceutical, food, the central air conditioning ventilation system of centralized air filtration, to ensure the cleanliness of pipeline.
Q:What is the relationship between the life of the filter bag and the dust collector?
High-temperature filter bag filter efficiency through the life of T0 bag is added to the established multiple is equal to the initial resistance according to the rated Q0 final resistance (usually 2 times) by the time, the quantity of dust at high-temperature filter bag filter, air filter has reached the maximum (also known as the standard amount of dust P0), so it can be considered the life of T0 high-temperature filter bag filter is the amount of dust HEPA filter to achieve the standard amount of dust P0 time. When the filter runs under low air volume Q1, at this time Q1 < Q0, so the filter life can be extended to T1, at this time T1 > T0.
Q:What are the advantages of degreasing filter bags?
Characteristics of oil filter bag:1, multi layer melt blown polypropylene filter material helps to filter liquid steadily and steadily2, super strong sewing multi-layer filter bag structure, with welded sealing ring3, spunbond shield almost eliminates fiber transfer4, interception of various soft and hard particles of impurities
Q:Can dust filter bag be cleaned by oneself? How can I clean it?
Washable.Main process steps for cleaning filter bag of dust collector:1, cleaning ash: the use of high-frequency vibration, the filter bag into the wall of the larger particles of dust as much as possible, and will not affect the fiber entanglement fastness, and to maintain good filter bag peel resistance.2, chemical experiment: extraction bag samples, detected by bag oil composition, professional instrument test to select the maximum washing raw materials, to wash the filter bag filter bag without causing any damage.3, cleaning: choose the appropriate washing raw materials, and strict proportion, low temperature water cleaning, water flow evenly, moderate intensity, no mechanical damage to the filter bag.
Q:What is the reason that the filter bag is broken and the strength of the filter bag is decreased greatly in the cement plant?
Four, blocked. The main cause of bag filter bag jam failure is:1. oil mist blockage. Oil mist plug is mainly boiler start or low load operation of oil feeding, did not take protective measures or measures to protect the bag caused by imperfect, increasing the residual resistance which will lead to the bag, even with strong cleaning is difficult to solve this problem.2. dust blockage. Fine dust in the process of filtering bag filter in fiber bag can enter into the interlayer, but ash can't connect the intrusion inside the bag dust filter bag blowing out all outside, so after the operation of the residual resistance of bag Months and years pass by. will continue to increase, in addition to low load boiler precipitator long time not clear ash would lead to this problem.3. dew paste bag. Condensation is a relatively common phenomenon of bag dust collector, refers to the wet gas in the pressure and temperature of the precipitation water saturation phenomenon, precipitation water temperature is called the dew point, saturated gas pressure the higher the dew point is low, the air humidity is high, the dew point temperature is high, when a certain amount of water in the air wet, wet gas is lower than the dew point temperature, the saturated water will precipitate in the air, namely producecondensation.
Q:What are the matters needing attention in the selection of the filter bag?
Electroplating refers to the salt solution containing pre plating, to be plated metal substrate as cathode, through electrolysis, the plating metal cation pre plating liquid on the substrate metal surface, a surface processing method of forming coating. The performance of the coating is different from that of the base metal and has new characteristics.
Q:How to choose material for filter bag of dust collector?
The temperature of flue gas under the premise of ordinary, only dust bag can be resistant to a temperature below 150 DEG C, these places, polyester, polypropylene, acrylic, nylon and other chemical fiber can be competent.
Q:What are the materials for liquid filter bags?
Polypropylene fiber (PP, PP PP): good abrasion resistance, high elastic recovery, is a kind of thermoplastic fiber, polypropylene felt is often used in pulse bag pulse filter bag and low temperature chemical pharmaceutical factory in smelting plant. Polypropylene precision range: 0.1--500 microns, the highest temperature 94 degrees.Polyester fiber (polyester, PE): polyester fiber with good performance at room temperature, is the main material in bag filter. It can withstand the operating temperature of 130 DEG C under dry conditions. It will harden at 130 DEG C; fade, brittle, and make the strength weaker.
