Dedusting systems,

In many enterprises, the energy consumed by dust collection systems accounts for up to 20% of the total factory energy.

The energy consumption of dust collection systems is driven by 2 factors,

• Ventilator electric energy,
• Electricity consumption through the compressor due to compressed air consumption.

In addition, the quality of the filter bags and whether they can be cleaned properly or not can increase or decrease the fluid resistance, and these factors also affect the electrical energy consumed.

CycloJet Units, produced with Asel Teknik&Industrial patent, reduce energy consumption by

• It has a unique double-walled construction with a separator cyclone on the outside and a bag filter on the inside. This structure is tailor-made by designing it specifically for each mineral with fluid simulations. In this way, 40% of the average dust is retained in the cyclone wall without ever reaching the bags. Thus, the bags are much less dirty, have low air permeability resistance and consume less electricity,
• The patented “CycloJet Smart” Intelligent Control System continuously monitors the flow rate drawn from the plant and corrects the fan speed to keep it constant. This results in energy savings of at least 35%,
• The CycloJet Smart software balances the compressed air consumption according to the flow rate being withdrawn from the plant. In this way, only as much compressed air is consumed as required, resulting in significant savings,

In this way, a sample 90,000 Nm3/h capacity dedusting system in Kütahya consumed 866,000 kW/year of energy instead of 1,354,000 kW/year.

Dust collection units with reduced efficiency can be replaced with CycloJet units and can be evaluated within the scope of “Efficiency Improvement Project”.

The use of DOMESTIC PRODUCTS, which President Recep Tayyip Erdoğan attaches great importance to, and the preference of domestic products in the procurement of goods to be made to public institutions are increasing their importance day by day.

President Recep Tayyip Erdoğan emphasized that the products produced in Turkey should be preferred primarily in the applications regarding the procurement of goods to be carried out by public institutions and organizations, and asked the managers to show the necessary sensitivity in this regard.

Asel Teknik company operating in Kütahya continues to be the face of Kütahya. Last month, the company, which was highly appreciated with its own project and production of dedusting machines at the inventors fair, was entitled to receive a DOMESTIC PRODUCT certificate for its inventions.

The company official Dr. Mechanical Engineer Barkın Minez, who made statements to Mining Turkey on the subject, said that 81% of the products we have invented are Domestic Goods and are advanced technology products. By completing the necessary application procedures, we were entitled to receive the Domestic Goods certificate we applied for.

We are happy to contribute to the use of Domestic Goods, which is very important for our country. Our state has many privileges for companies with Domestic Goods certificate. We proudly offer these privileges to all our customers as Asel Teknik Endüstriyel in Kütahya.

As you know, a while ago, Istanbul Chamber of Commerce launched the campaign “ ‘I PRODUCE FOR TURKEY, I CONSUME FOR TURKEY’ ”.

Turkey is now motivated to transition from an import-based consumption economy that negatively affects the volume of industrial production, employment and technological development momentum as well as foreign exchange reserves;

to a model of growth through production.

A domestic industry that produces products and solutions in every field from textiles to logistics, from construction to agriculture will be the critical player of this period.

Figures in almost every sector show that the current account deficit can be proactively reduced through value-added production, branding and changing consumption habits.

Producing every product that can be made in Turkey, even though it is imported, in our country and consumers preferring domestic products with a national consciousness can be Turkey’s new power.

What is a Domestic Goods Certificate?

It is a document showing that the product produced contains at least 51% domestic contribution.

By whom is the Domestic Goods Certificate issued?

Domestic Goods Certificate is issued by the chambers and stock exchanges affiliated to TOBB. In order to issue a domestic goods certificate, it must be calculated by the expert and financial advisor, and the company must also undertake that at least 51% of the product produced is domestic goods.

What are the Advantages of the Domestic Goods Certificate?

Producers who obtain a Domestic Goods Certificate are granted a 15% price advantage in public tenders. In other words, SMEs and large-scale companies that obtain a Domestic Goods Certificate can offer 15% more price in public tenders.

Industrial fans are oversized, high-performance fans designed for use in industrial environments. They can be used for many different purposes, such as ventilation, cooling, heating, humidity control, ventilated storage and ventilated production.

Industrial fans are generally designed to produce high airflow and pressure. However, different types of fans are available for different applications. For example, different types of fans can be designed according to factors such as impellers, number and shape of blades, rotor speed and diameter of the fan. Industrial fans generally use compressed air or water for cooling.

While industrial fans are used in large plants and factories, they can sometimes be used in commercial buildings and stadiums. These types of fans are ideal for large volume areas that require high airflow and pressure.

However, because industrial fans are powerful and large, they can be dangerous if not used correctly. For this reason, they should be installed, maintained and used by specialists.

Dedusting Systems

The First Step to Sustainable Performance and Economy

Ventilators…

One of the most important aspects of the design of a dust collection / ventilation system is the ventilators…

When it is incorrectly calculated/selected, it is one of the biggest factors in the inability to provide performance or inefficient operation throughout the life of the system.

A fan operating at less than the required flow rate already means that dust cannot be collected.

A fan that operates at a higher flow rate than necessary can cause many problems, from the waste of your most valuable product to the perforation of dust collection ducts.

The fan shown in the graphic on the side;

Is it at 2,000 m3/h flow capacity?

Is it at 1,000 m3/h flow capacity?

500 m3/h flow capacity?

All true or all false…

Flow rate alone is a meaningless term for a fan.

For it to be meaningful, it has to be accompanied by the question at least at what pressure?

If you have calculated losses for a system and calculated a flow rate to overcome this resistance, but the losses or the fan design is not correct, nothing will go right. In short, you will be on the wrong left or right side of the graph. So either you will not be able to collect the dust with too little flow, or you will lose product with too much flow.

Therefore, it is not possible to build a dust collection system with high performance and high energy efficiency with a poorly engineered fan selection.

Do you doubt this?

Please compare the filtered air flow rate from the chimney with the fan label value,

Or check if your product is included in the dust analysis you collect.

Many people report not getting even half of the fan label value and finding product in at least 20% of the filter dust…

Other parameters related to sustainable performance and efficiency will be continued in the next issues…

Dedusting systems take a very significant share of the general production costs of enterprises with the electrical energy they use for their fans, their compressed air consumption and their consumable filtration elements.

An inefficient dust collection unit not only threatens employee health, but also causes both loss of reusable product and wasted costs.

The most common causes of inefficiency are;

• Faulty collection ducts,
• Incorrect fan selection,
• Insufficient shaking air,
• Incorrect filter element selection

Asel Endüstriyel tries to use advanced engineering techniques to prevent these errors that may cause loss of efficiency in the dedusting systems it has established with 20 years of industrial industry experience.

Engineers within Asel Industrial design each dust collection system specifically for the customer.

First of all, solid modeling is done for dust collection ducts. Then these ducts are run virtually with fluid simulation software. The duct project is completed with the pressure loss from the system and flow data corresponding to the optimum velocity.

Thus, the duct diameters, duct form and ventilator selection are chosen correctly in terms of both efficiency and energy efficiency.

The most common mistakes in dust collection systems are narrow ducts causing excessive resistance or too wide ducts causing dust settling.

Cleaning/shaking the right filter element with the right air

Again, one of the factors that reduce the efficiency of dust collection units the most is the selection of the wrong filter element.

In the process,

• Dust load
• Grain distribution of the powder,
• Dust stickiness,
• Powder abrasiveness,
• Nem,
• Temperature

It is very critical to study such factors correctly and select the appropriate filter element.

An incorrectly selected filter element will not allow you to work efficiently even if everything else is in order.

Another critical issue is the cleaning/shaking air.

• At the appropriate pressure,
• Appropriate flow rate,
• Appropriate quality

The use of purge air is very important.

The most common mistake is that the diameter of the air line brought to the unit is smaller than it should be and air is supplied at a much lower pressure than that produced in the compressed air center.

Another issue is the condensation that occurs in long and uninsulated air lines and the problems caused by cleaning with wet air.

The most important points to be considered for an effective dust collection system with minimum operating costs are briefly explained in this article.
