Dust Collector For Air Filtration

Oleg Systems Co. designs industrial dust collection systems. Dust collecting equipment is available in numerous designs utilizing a number of principles and featuring wide variation in effectiveness initial cost operating and maintenance expense space arrangements and material of construction.

One of the most widely used type of dust collector is Fabric Dust Collector.

Fabric arresters are high efficiency medium cost collectors. The effectiveness of passing air or gas through a fabric at low velocity has been recognized and used for many years in air cleaning devices. Fabric is arranged in envelope or tubular stocking shapes. While removal appears to take place by a staining action of the media in reality dust collection is obtained by building up a mat of the material on the dirty side of the media. This mat provides the actual filtering or straining bed. By means of this bed a high degree of removal is obtained even on submicron size particles.

The dust collectors are used extensively in industry for a wide range of applications. They require more space than most other types of air cleaning devices necessiating outdoor installation in most cases.

The usual fabric is a specially wooven cotton altough wool paper glass cloth and synthetic fabrics may be used in certain applications. In recent years glass cloth has come into wide use because of silicone treatment of the glass fibers and employment of reverse flow techniques for cleaning. Silicone treatment provides a lubricant between fibers and increases fabric life.

Fabric collectors are limited to air conditions dry enough to prevent condensation or free moisture deposition on the fabric. With hygroscoping materials there will be a bonding tendency between particles and fabric under high relative humidity even though no condensation takes place. Maximum recommended temperature for cotton fabric is 180 F for wool 200 F. Higher temperatures can be handled by using synthetic materials including nylon or orlon fabrics as well as glass cloth and occasionally fine metallic mesh. The synthetic fabrics mau be used up to 300 F while glass cloth is acceptable to 550 F.

As dust is collected on the fabric resistance to air flow increases. Periodically the fabric must be reconditioned by shaking vibrating reverse jet or reverseflow collapse which agitates suffitiently to remove the bulk of adhering material allowing it to drop into the dust hopper. In most collectors air flow must be stopped during reconditioning otherwise released material will be reentrained and redeposited on the fabric. Sufficient dust must adhere to the fabric to maintain the dust mat needed for maximum efficiency; therfore after reconditioning the pressure drop will be considerably higher than loss through new fabric.

Rate of flow through the media varies with dust collector type application and dust concentration. Ratings are usually selected so pressure drop will not exceed 5″ WG. The smaller the particle the more rapid the resistance rise for a given loading. For the same air flow rate and dust loading resistance rise increases directly in proportion to time.

Some spesific types of Fabric Dust Collectors manufactured by Oleg Systems Co. are:

IntermittentDuty Fabric Collectors

These types may use either envelope or stocking arrangement of the fabric but will generally employ shaking or vibrating as a means of reconditioning. Periodically Uusually at 4 to 6 hour intervals0 the air flow must be stopped to effect reconditioning thus the classification “intermittent”.

MultipleSection ContinuousDuty Automatic Fabric Collectors

The disadvanteges of stopping the air flow to permit vibration and variations in the airflow can be overcomed by using of sectional arresters allowing continuous operation of the exhaust system as automatic dampers periodically take one section out of service for reconditioning the fabric while the remaining sections take the entire gas volume.

ReverseJet Fabric Collectors

The reversejet type differs from the conventional arrsters in its use of high pressure air to clean the fabric. One type uses high pressure air 30″ 40″ WG from a travelling “blow ring” to dislodge the collected cake from inside the fabric tube. Another type uses high pressure compressed air 100 PSI to break the dust cake from the exterior of the fabric tube or envelope by the intermittent application of reversejet compressed air.

ReverseFlow Collapse ContinuousDuty Collectors

Reverseflow collapse cleaning is generally used with glass media which is fragile and requires a gentle cleaning technique. Reversing the glass flow provides a gentle collapse of the fabric usually in a “four point star” braking the dust cake which falls by gravity into the hopper.

Business English Training Keys To Success

Of course where the market appears so do the companies set up to capitalise. Deciding on a language training provider can be daunting and the unregulated nature of the training industry in most countries can mean huge variation in the quality of the training and therefore huge variation in the return on investment for the companies management. So what is it that makes some training effective while other programmes are a waste of time? How can companies minimize the risk of investing in lameduck language training?

The first piece of advice is to make informed decisions on language training providers based on information from reliable sources. Websites brochures marketing emails and fliers can hold a great deal of information but the most reliable source is a person who has attended or been involved in training elsewhere. One must be careful though as the famous providers those with strong brand recognition may be wellknown as a result of an overemphasis on marketing and not necessarily on quality. Big is not always better when it comes to training providers; larger establishments usually struggle to find enough good teachers and compromises are sometimes made. Moreover while smaller schools tend to be run or heavily influenced by the most important people the teachers larger training centres inevitably move towards being driven solely by the bottom line. This is not to say that one should shy away from providers with strong marketing; were looking for providers who like to show off their benefits after all. Be wary of those who arent willing to talk about their benefits.

Lets stop talking about marketing. We are discussing education and in reality the quality of education comes down to two things; the quality of the teachers and the quality of the courses. Quality of customer service and organisation and coordination by the provider also play a part in your satisfaction but in terms of return on investment its the teachers and the courses that are going to deliver.

Ask about the teachers. Many companies put blind faith in the training provider that they will provide the right people for the job inevitably causing disappointment when the wonderful teacher promised in the sales pitch to turns out to be useless. Ask to see their resume ask to meet them. A good training provider will be proud of their teachers and willing to show them off on demand. When you see the resume bear in mind that experience isnt everything. While you dont want a brand new teacher with little experience many teachers with decades of experience can seem burned out as if they have lost the passion for their profession. Look out for teacher training qualifications and look for their own educational background and work experience. How can someone who never went to university or never worked in a business environment be expected to teach your staff about contemporary business communication? Personality is important so choose teachers you actually like choose teachers who your staff will look forward to spending time with choose teachers who have passion and commitment to their job written all over their face.

Ask about the courses. More to the point demand courses which are designed to fit your exact needs. Many training providers use generic business English courses which are on the whole eurocentric nonspecific and rapidly out of date. The English your sales team needs is very different from the type of language required by your management team or customer service team. Demand courses designed for your industry; if youre involved in shipping make sure that topics are related to shipping or you could find your staff learning language they will never be able to use. Decide what aspects of your staffs English to focus on; are they regularly emailing meeting clients giving presentations writing reports or proposals or using the telephone? Demand that your staff learn the right skills and language. But also gauge the providers ability to provide enjoyable programs. Endless photocopied handouts are plain boring. Are the providers going to use communicative interactive activities? Are the providers going to use modern business technology to teach modern business techniques? What are they going to do to motivate your staff? These are questions to bear in mind when perusing websites and meeting the sales people from the schools. A final tip for effective language training: training is more effective if classes are small and trainees are divided based on their level of English and specific job responsibilities. Ask the provider how they will assess your staff and how they plan to organize the trainees into groups. Steer clear of anyone willing to mix abilities and compromise quality by filling classes with dozens of trainees who each have their own learning objectives.

Make sure you clearly define your objectives and choose the provider who shows you just as clearly how they are going to meet your objectives through enjoyable professional communicative training delivered by happy qualified devoted teachers. In Jakarta Indonesia one professional training provider is leading the way in language programmes for businesses. Take a look at kursus bahasa inggris to see how its done.
