A commonly overlooked area of inefficient compressed eaxmple use je dust collector pulse-jet cleaning — either bag sock type, or zystem flow filter jet air filtration system filters example. Dust collector systems are vital to many plant operations, particularly with respect to meeting both indoor and outdoor air quality standards. They are also often used to collect income-producing product.

At the heart of a pulse-jet type dust collector is the proper installation and availability of compressed air. Proper operation of dust collectors is critical to minimizing cost and maximizing system effectiveness. There are many types and sizes that use a pulse of compressed air to clear the bag or filter. This pulse is usually controlled by a timer, which may or may not have an auxiliary demand control. Tilters timers are generally set by the operators to what they believe is appropriate for proper cake removal and bag life.

A properly working demand pulse control will dramatically lower the operating cost. In this article, we review the operating principles of both basic types of pulse-jet dust collectors — bag sockand reverse flow filter. The dust is collected on the bag or fingers, and when exammple cake of dust is of appropriate thickness and structure, a pulse or pulses of compressed air is used to hit or shock the bag and knock the cake off.

This pulse may sometimes be accompanied by physical shaking. Depending on the design, reverse airflows may also be incorporated. When systsm cake filtratuon removed correctly from the dust collector, the system removes dust from its assigned environment and has a normal bag life. When the cake is not removed efficiently, the dust collector does not always continue to remove dust effectively from its assigned environment, and the bag life can be significantly shortened.

Dust jet air filtration system filters example system designs specify the jet air filtration system filters example air inlet pressure to jet air filtration system filters example manifold and pulse valves filtrrs for effective dust removal. Based on this pressure, the pulse valve ciltration a given volume or weight of air to the bag at a predetermined fitration to strike and clear the cake.

The actual amount and weight of the air is dependent upon the pulse nozzle being fed compressed air at a pre-determined minimum and Jet Air Filtration System Filters On steady pressure. The dust collector must receive the correct pressure or close to it and a foltration repeatable pressure level for each pulse, particularly if timers are used to control the pulses.

The operator may experiment to find the right timing sequence at a desired compressed air inlet pressure. However, if this pressure varies, the performance will be inconsistent and unsatisfactory, and it may also use a great deal more jwt air. This momentary airflow reversal is induced by a short burst of compressed air similar to pulse-jet bag dust collectors. The compressed air is released from the storage receiver by a fast-acting, high-flow diaphragm valve.

This pulse of air dislodges the accumulated dust from the element. The dust then dumps into the hopper or collector drawers. Each pulse cleans a aair of filter Jet Air Filtration System Filters 01 elements, leaving the remaining cartridges available to continue filtering the air.

Each diaphragm valve typically operates one pulse-jet blow pipe. Each pulse-jet blow pipe contains a nozzle for each cartridge — usually up to three cartridge filters per pipe. As the pulse filtratoin air reaches the nozzle, it is accelerated through the smaller diameter, creating a low-pressure center, or Venturi, which pulls in surrounding air through the filter in a counter-flow direction.

The rated flow of compressed air per pulse is usually 3 to 6 cubic filyration, with normal pulse durations of. One valve typically opens every jet air filtration system filters example seconds. Obviously, there are other designs with different specifications.

Most of the time there will only be one valve opening every 15 seconds, but sometimes there could be two or more pulses simultaneously. From a compressed air standpoint, the supply of proper compressed air is the same.

Whether pulse-jet direct or pulse-jet reverse flow, the basic valve operation is very similar and will vary by model, brand, conditions and material.

Regardless of whether the pulse-jet dust collector is bag or filter filtation, the critical support system of piping, storage and controls is important for not only the operating performance and maintenance cost, but also the compressed air actual demand and its effect on energy costs.

The use of a demand type jet air filtration system filters example control, as opposed to timer activated, allows the operation to run with optimum compressed air usage. This is commonly referred to as an automatic pressure differential pulse controller.

Flow rate is the average flow of compressed air in cubic feet per minute cfmeither required by a process or delivered to the system. Rate of flow is the actual rate of flow jet air filtration system filters example compressed air demand expressed in cfm — regardless of duration. Even relatively small air ket in cubic feet can have a very high rate of flow, if they occur over a very short time period.

Dust collectors have this characteristic. Sequence controllers ait have a very significant impact on the required rate of flow. For example, Figure 1 shows a dust collector system that has two pulsing valves that use 6 cubic feet over. Both valves open together every 7 seconds. If this is the case, and the dust collector performance and integrity are a problem due to low entry pressure at the pulse, appropriate storage and piping can be a very effective correction when properly implemented.

Although the actual flow is only foltration cubic feet Figure 1its rate of flow is cfm, meaning that piping and all additional filtrafion have to handle this burst as if it filtrstion scfm in order to deliver the air at an appropriate pressure. Additionally, a standard regulator cannot handle this. In short, 12 ft3 of air has. If this does not filtters, the entry pressure collapses and the pulse-jet becomes ineffective.

Figure 2a illustrates a very common installation or system situation that causes jet air filtration system filters example airflow. This occurs because the proper rate of flow was not identified for the dust collector cleaning action — either prior to sysgem installation or prior to some operational change. Feed line sizing, regulator sizing and air supply all require an identified rate of flow.

You cannot use average flow rate. Figure 2b shows the corrected ecample, in which compressed air stored in a properly sized vessel supplies the pulse air required in time through jet air filtration system filters example large pipe. The restrictor refill valve slows filttration the tank refill, protecting the main air system.

In the configuration shown in Figure 3a, entry air to the dust collector manifold was controlled by manually cracking the 2-inch ball valve to restrict the flow and protect the main compressed air system. The plan was for the operator to watch the pressure gauge and manually adjust the valve as required. In actual performance, this did not work. The plant experienced poor results, short bag life, and could not run the automatic demand control. A jet air filtration system filters example designed system is displayed in Jet air filtration system filters example 3b.

Performance improved, and the automatic demand controls run well fklters use less air, resulting in longer bag life. Standard regulators usually will not filtraation for the normal pulse duration.

The first installation, displayed in Figure 4a, included one regulator, and a second parallel regulator was added. It still did not work, and the Jet Air Filtration System Filters 15 collector header fell to 50 psig. To address the issue, the regulator was replaced with a properly sized receiver and restrictor valve refill, which can be seen in Figure 4b.

As seen in the previous case studies, issues with compressed air delivery and supply may create an ineffective pulse. Here are a couple of recommendations to ensure examle effective pulse:. Some dust collector manufacturer instructions will specify a filter and regulator. Be sure the regulator selected will fully open in the time allowed for the application.

Otherwise, the installation should be augmented with a properly installed air receiver fed with psig system pressure, an adjustable fulters valve, and an appropriate check valve as shown in Figure 4b on the 2-inch feed to the vertical jet air filtration system filters example receiver.

Install the air receiver near the dust jet air filtration system filters example entry. When one pulse valve opens, expect a 1-psig drop. That drop should not exceed 3 psig. If two jet air filtration system filters example open simultaneously, the minimum entry pressure of 90 psig is still covered. Pulse-jet dust collectors are a continuing source of leaks, particularly when pulse-jet diaphragms fail and become very large compressed air leaks.

Often, leaks are hard fikters hear, and sometimes — when first heard — they are ignored in the hopes that someone else will notice and repair it. After all, it is a hot or colddusty and jet air filtration system filters example job, and it is often above ground.

There are some excellent electronic monitoring systems available that will identify leaks from failed solenoid pulse jet valves. For these systems to perform as designed, the compressed air supply should deliver solid, consistent performance at the point of use. When ejt plant or operation with significant dust collecting is audited, it is very rare to find anyone in operations who is aware of what the dust collectors operating specifications are and how or why the pipe sizes were selected.
