Bag filter bag filter is to determine the efficiency and operating temperature of the key components, the cost of bag filter replacement bag filter is the main maintenance costs. Therefore, the working life of the filter bag is related to the operating status and cost of the precipitator!
To extend the life of dust filter bag method :
1 use the appropriate filter
Selection of filter material should be based on the gas temperature and chemical properties; particle size, weight, shape, whether pecking and dust concentration, filtration speed, cleaning methods, emission concentration and bag filter work system and other factors considered .
Under normal circumstances, the choice of pulse jet bag filter needle felt; sub-chamber anti-blowing bag filter or mechanical vibration bag filter use woven cloth.
2 well-designed structure
The structure of the filter bag should meet the filter and cleaning requirements of the bag filter which is matched with the filter bag. The utility model has the advantages of convenient installation, reliable sealing, pursuing the corresponding filtering area and good filtering state, is easy to clean and avoids the wear as far as possible. Matched with the relevant components.
Such as outside filter synthetic fiber filter bag and the frame should be loose with the outside filter glass fiber filter bag should be closely spaced with the vertical spacing of the small frame; filter bag filter bag should be considered and set the force.
3 superb sewing technology
Advanced technology, sewing size to meet the design requirements, and by filter type and temperature, reserve shrinking size; fully equipped, suture needle spacing reasonable, no jumper, broken line, suture to meet the requirements; Accessories quality, with Reasonable, no burr or fracture damage to the filter bag; The entire filter bag no holes, jump yarns, fouling and other defects, and have the appropriate packaging, storage or transport on the way not damaged or damp. Fiberglass bag should not be heavy pressure, storage period is too long, otherwise it will affect the service life.
4 the correct method of use
External filter bag installation
Pocket mouth and porous plate reliable seal and fixed;
The filter bag is vertically suspended below the perforated plate;
Adjacent filter bags do not collide with each other;
Bag with the frame with the right, straight frame without burrs.
Internal filter bag installation
The upper end of the filter bag is provided with a bag cap and is hung on the beam of the precipitator through a hanging device so that the lower end and the lower bag are reliably sealed and fixed;
Filter bag installation should adjust the tension to achieve the specified value, so that the filter bag filter and blowback does not loosen and fall off, and use the first week and the first month and then adjusted once;
Bag filter parts (deflated collars) with the correct, all parts should not have burrs or broken.
Reliable and effective cleaning
Bag in use, grey dust area gradually increased ash, pressure rise, should be effective cleaning, dust isolation, so that the pressure inside and outside the filter bag to maintain within the set range.
Prevent sudden abnormalities
Bag filter in operation, should prevent unexpected abnormalities, such as a sudden increase in gas temperature, or corrosive gases into, or gas temperature suddenly dropped below the dew point and so on, subject to temperature, humidity, chemical corrosion, mechanical wear and tear Or impact and other factors beyond the tolerance of the bag damaged.
PSA H2 generator is generally a PSA purification equipment to get pure H2 from the gas mixture with H2 as the main component.
High purity H2 Generation System mainly comprises of Ammonia decomposition device for H2 generation.H2 pressurization system, PSA H2 Generator plus gas storage tanks....
Based on the requirement of gas production line, the H2 source, takes liquid ammonia as the raw material, which decomposes into the mixed gas of about 75% H2 and 25% N2 under the action of catalyst of Nickel. This will greatly improve the reliability and randomness of the H2 system, which make it convenient to maintain the system, to ensure the stable operation of the main production line.
The advantage of PSA H2 Generator
â—†Easy installation
The equipment is of compact structure, wholly skid-mounted, low space requirement without the infrastructure investment and small investment.
â—†It is more economical than other ways of H2 supply.
Pressure Swing Adsorption technology is a kind of easy and simple way to supply H2. It takes the decomposed gas from ammonia or natural gas. The energy consumed is only the electricity consumption of the H2 compressor, which endows it with such advantage of low running cost, low energy consumption and high efficiency.
â—†Integrated design of mechatronics and instrumentation makes the automatic operation realized.
Imported PLC fully controls the full automatic operation. The flow rate, pressure and purity of H2 are adjustable and can be displayed continuously; alarm of pressure, flow rate and purity can be set and remote automatic control and testing or measuring can also be realized, therefore, the unmanned operation is truly realized.
â—†Peak/Fail Safety system
Alarming and automatic start-up function of Peak/Fail back-up system can be configured for the user to ensure the safe and reliable running of the system.
â—†The high purity of components and parts is the guaranty of the stable and reliable running.
The key parts such as pneumatic valves and solenoid valves are all imported from Germany or Japan with advanced configuration. They are operated reliably with fast switching, and long service life of millions. They are of low failure rate, easy maintenance and low maintenance cost.
â—†Oxygen content can be displayed continuously, and if it is beyond the limit, there will be automatic alarming.
On-line monitoring of H2 purity to ensure the stability of the H2 purity required.
â—†High quality molecular sieve
The high quality molecular sieve has large adsorption capacity, high compressive performance with long service life. The service life of normal operation is 8 to 10 years.
â—†Advanced filling technology of molecular ensures the working life of the equipment.
