  • Clean your test sieves to maintain accurate results

    A standard process in analytical laboratories is sieve analysis, the practice of accessing the particle size distribution of a granular material. The trouble is, sieves prove quite the challenge to clean thoroughly enough to get all the contaminants out of the mesh. Every last grain stuck in the sieve must be removed to gain accurate analysis. A solution has been found in the use ...

  • Filter Your Air with Cartridge Dust Collector

    A cartridge dust collector uses filtering cartridges and is a self-cleaning dust collector. The cartridges it uses are made from synthetic fibers and cellulose that is treated chemically. This ensures the particles are efficiently collected without forming an excessive pressure drop in the system. Structure A cartridge dust collector uses an air-jet cleaning structure to preserve ...

  • Ineffective cleaning in generic baghouses

    ABSTRACT: Background In a typical “generic” baghouse application, the cleaning is accomplished by back-flushing the filter with compressed air that travels through an orifice hole in a purge tube (blow pipe) and through a venturi. A typical generic cleaning system allows dust to be filtered at an air-to-cloth ratio of 5:1. That means for every 5 CFM of airflow, there is 1 square foot ...

  • Advantages of cleaning without a venturi in baghouse collectors

    ABSTRACT: Background The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In order to clean a row of bags in a reverse pulse jet baghouse first the flow of filtered air must be momentarily stopped and then back flushed or “induce” air to knock the dust cake off the outside of the filter media. A venturi at the top of the ...

  • Improving the cleaning cycle in baghouse collectors

    ABSTRACT: Background The reverse pulse jet baghouse has been around for over 45 years and the cleaning cycle has not changed very much since that time. The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In a generic baghouse, the cleaning system is comprised of a blowpipe that is located typically approximately three inches above ...

  • New Nozzle Technology “Cleaning More with Less”

    This technical paper will explain the new nozzle technology developed by Scientific Dust Collectors that allows high air-to-cloth ratio baghouses to use 80psig of compressed air instead of the industry standard 100psig.   The reverse pulse jet baghouse has been around for over 50 years and the cleaning cycle has not changed very much during that time. The cleaning cycle is the most important ...

  • Tank cleaning in Abu Dhabi case study

    In 2008 we signed an agreement with an Abu Dhabi based industrial and utilities contractor. They wanted to increase their portfolio by offering tank cleaning services. Over a period of four months we trained a number of their operators and sourced new equipment to enable them to approach new clients. In 2009 we were awarded a contract to clean two crude oil tanks. Utilizing local labour, the new ...

  • Lanes cleans Cascade

    It is not just drains that benefit from Lanes’ cleaning skills. Earlier this year, the team was asked to help spring clean the Grand Cascade, a spectacular water feature at The Alnwick Garden, one of the most popular visitor attractions in the UK. The Grand Cascade is the largest water feature of its kind in the country, with 7260 gallons of water per minute tumbling down a series of 21 ...

  • Cycle Stop Valve replaces four Variable Speed Pool Pumps case study

    This pool has 4 water features, a slide, a waterfall, a spa cascade, and a wet wall. I required the ability to run each of these water features independently. This pool also has four cleaning modes, two sets of in floor cleaning nozzles, skimming, filtering, and vacuuming. In addition this pool also has a 50 foot zero entry lip. In order to accommodate all the above a typical configuration would ...

  • Industrial Carpet Cleaners for Powerful Cleaning and Extraction

    Using industrial carpet cleaners is a three-step process: Apply pretreatment solution to the carpet. Inject and extract cleaning formula carpet with the wand. Allow the carpet to dry. Industrial carpet cleaners, as a result, need to offer effective cleaning and they should be able to extract maximum amount of dirt and moisture from the carpet. ...

  • Pleatable UPE membrane media in pulse-cleaned dust removal air applications

    Media Selection For initial tests, three media were selected for comparison. These structures are all designed for use in pulse-cleanable cartridges, with processing on blade pleaters. Arioso™ M7001-11 is a Solupor® ultra-high molecular weight polyethylene (UPE) membrane designed for F9/MERV16 efficiency at very low resistance laminated to a 200 gsm, stiff, high permeability ...

  • Mixers and Flowmakers: Cleaning of stormwater tank

    Deposits in an 18 m diameter stormwater tank made it necessary to clean the tank several times a year. A POD-I mixer was installed. The mixer has an 11.0 kW motor and the number of propeller revolutions is 1500. The relatively small propeller creates a strong, concentrated jet. Operation can take place at a very low liquid level - high velocities are created at the bottom -and the deposits ...

  • Fine particle capture in biomass boilers with recirculating gas cyclones: Theory and practice

    This paper addresses the theoretical development and experimental validation of optimized recirculating reverse-flow gas cyclones. The simulation of these systems is based on the predictive properties of a finite diffusivity model, modified to include partial recirculation of the cyclones' emissions. Experimental validation was obtained at laboratory and pilot scales at low temperatures (up to ...

  • Laboratory, pilot and industrial-scale validation of numerically optimized reverse-flow gas cyclones

    This paper addresses the experimental validation of the optimum design of reverse-flow gas-cyclones, obtained through the solution of a numerical non-linear optimization problem, viz. maximizing cyclone collection. The simulation model is based on the predictive properties of a finite diffusivity model, where the particles' turbulent dispersion coefficient is estimated through an empirical ...

  • A novel harmonic mitigator-based 12-pulse rectification for vector-controlled induction motor drives

    This paper presents an optimised 12-pulse autotransformer-based AC–DC converter with reduced kVA magnetics for reducing the harmonic distortion in AC mains current in a vector-controlled induction motor drive (VCIMD). The proposed AC–DC converter results in elimination of fifth, seventh and 11th harmonics in the supply current. The proposed system consists of an autotransformer and a tuned ...

  • Pilot and Industrial-Scale Experimental Investigation of Numerically Optimized Cyclones

    A new geometry of reverse-flow gas cyclones obtained by numerical optimization was shown at the laboratory scale to be significantly more efficient than other high-efficiency designs. However, it is usually recognized that experimental results obtained with laboratory-scale or sampling cyclones cannot be extrapolated to pilot or industrial scales. The present paper confirms, at these larger ...
