Authorities and Industry Experts draft new legislation to replace the Environmental Quality Act 1974
Updated date: 06/11/2019
KOTA KINABALU, Nov 6 - The Department of Environment (DOE) with the Ministry of Energy, Science, Technology, Environment and Climate Change (MESTECC) is enacting a new law, called the Environmental Protection Act to replace the Environmental Quality Act of 1974.
Deputy Chief JAS director (Operations) Wan Abdul Latif Wan Jaafar said the draft law was drafted and was under review before being brought to Parliament next year. The new law, he said, was expanded in scope to the existing law, which includes environmental pollution involving air, water and hazardous toxic wastes while many new contaminants were detected but were not included in the act.
''The enactment of the new act has taken into account all of these pollutants as well as current issues of development and many things we look at,'' he said after opening the two-day Environmental Quality Act 1974 seminar starting today with 570 participants.
He said the new Act would also strengthen the implementation of DOE tasks in line with the latest developments in management and environmental issues including the use of the best pollution control technology and the country's obligations to international conventions.
''In this regard there are two important issues, first the scope of jurisdiction is expanded taking into account current pollution and new pollutants. Both of us have higher penalties and penalties for environmental offenses,'' he said.
Meanwhile, Wan Abdul Latif said the study conducted for the restructuring of the industrial buffer zone in Pasir Gudang Johor to be closer to home was not yet finalized.
He said the study was conducted by several experts to establish buffer zones between industrial and residential areas as well as schools following the air pollution incident.
He said the Pasir Gudang industrial area had been around for a long time but housing and schools were being built closer to the industrial areas.
''The study also saw moving industrial areas and schools located closer together so that the distance between the industry and the residential and school areas was safe.
''The study is yet to be finalized before it is presented to the government,'' Wan Abdul Latif said.

Dust Collector ¨C Baghouse

Jan 23, 2019
What is a Dust Collector/Baghouse, and how does it work?

A dust collector is a type of pollution control equipment designed to collect and store dust, particulate, and particles from industrial exhaust streams. This equipment is widely used to recover valuable granular pollutants from gaseous exhaust streams in many different industries including woodworking, steel, and packaging. A pulse-jet bag filter dust collector is designed to achieve maximum operating efficiency while reducing maintenance cost and time.

Bag filters are generally used in applications requiring high yield recoveries from pneumatic transport systems or for the removal of hazardous materials from the working environment

Pulse-Jet Bag Filter Dust Collector

The pulse-jet bag filter dust collector is constructed from a series of modular components which allows for standardization yet retains the ability to be completely flexible with selection, sizing, materials of construction, filter media, and equipment arrangement. As the dust laden air enters the dust collector housing through the inlet duct, the baffle plate located inside of the inlet act as a pre-filter and prevents re-entrainment by guiding the gas stream downward uniformly. The baffle plate deflector directs the heavier dust particles into the hopper for collection.

The remaining lighter dust particles are drawn against the outer surface of the filter bags, where they are retained and stored. Clean air then passes through the filter bags and leaves the clean air chamber through an outlet duct.

As dust accumulates on the filter bags, periodic cleaning of the bags is important in order to maintain continuous operation. This periodic cleaning of bags is achieved by introducing a timed, momentary pulse of compressed air through a specially designed blow pipe, with nozzles mounted above each filter bag.  An equal amount of compressed air is blown vertically downwards into each bag. Each row of bags receives a short pulse of compressed air of approximately 100 ~ 200m sec duration. The high pressure compressed air creates a shockwave down each bag causing it to release the majority of dust formed around the outside. The removed dust is then collected in the hopper. Only a portion of the filter bags are cleaned at one time, allowing the remaining filter bags to continue their filtering action. This means equipment does not need to be shut down, in order to clean the bags.

Bags are held firmly in place at the top by clasps and are usually sewn shut at the bottom. In another design, a snap ring is sewn into the top of the bag which fits into the tube sheet opening. The cage slides inside the bag and the top of the cage sits on the tube sheet. Dust-laden gas is filtered through the bag depositing dust on the outside surface of the bag. Pulse-jet cleaning is used for cleaning bags in an exterior filtration system as well.

Pulse-Jet Off-Line Pulsing System

Pulse-jet baghouses can also be compartmentalized. In this case, pneumatic controlled dampers located both at the dust laden inlet and clean air outlet are used to stop the flow of dirty air into the compartment. Each compartment is equipped with pulse valves that supply compressed air into the blowpipes above the bag rows in the compartment. During the cleaning cycle, the inlet and outlet pneumatic damper closes stopping the air flow through the compartment. The pulse valve opens for about 0.1 second, supplying a burst of air into the bags for cleaning. The compartment remains off-line for approximately 30 seconds although this time period can be longer or shorter if desired. The inlet and outlet pneumatic damper then automatically re-opens bringing the compartment back on stream (or known as “on-line”).

Alternate compartments are cleaned successively until all the bags in the baghouse have been cleaned. The cleaning cycle in each compartment lasts about 40 to 120 seconds. This cleaning is called off-line cleaning. It is frequently used on fabric filters installed on coal-fired boilers and municipal waste incinerators allowing very thorough bag cleaning while the baghouse continuously achieves very low emission levels (less than 50 mg/m3).

ESP or Electrostatic Precipitators are considered obsolete by most of the air pollution control experts. Their lower efficiency and their very high CAPEX,  made them disappear year after year from the dust control companies' catalogues.
As the particulates emission regulation is becoming more and more stringent, many industrials that already have one or several ESPs installed, need to add a second filtration system (ESP, baghouse filter...) to comply with the emission limit.
MJ offers a complete service of ESP conversion into a baghouse filter, thus offering many relevant advantages:

  • Increase considerably the particulates and dust removal efficiency
  • Reduce the upgrade costs
  • Optimize the process footprint
  • Have access to MJ's large range or after sales services
