Asphalt Plant Filter System

An asphalt plant filter system is equipment used during asphalt production. This system filters particles, gases, and fumes generated within the dryer during the production of hot asphalt at the asphalt plant. This aims to reduce harmful particles and gases released into the environment. The filter unit also retains the stone dust (filler) dried within the dryer, using bags, and transports it to the filler silo or filler elevator for use. An asphalt plant filter system generally consists of three main components:

Filter Bags: These bags capture particles and fumes as they pass through the gases in the asphalt plant. Filter bags are generally made of high-temperature-resistant, special materials.
Filter Suction Fan: The fan in the filter system sucks in gases and particles from the asphalt plant and directs them toward the filter bags. This way, the gases and particles are filtered, and the cleaned air is released into the atmosphere.
Cleaning System: Filter bags can become clogged with particle accumulation over time. Therefore, the filter system is usually equipped with a cleaning system. The cleaning system cleans the filter bags at regular intervals and removes the particles.

The asphalt plant filter system is designed and manufactured in accordance with the plant’s capacity, geographical location, altitude of the site, and weather conditions. This system is used to meet dust emission values specified in international standards.

The vertical cassette bag system is part of the asphalt plant filter system and provides easy replacement. The cassette bags used in this system capture particles and fumes during the filtration process. The bags can be replaced and cleaned regularly. This ensures the filter system continues to operate effectively and keeps dust emissions under control.

The asphalt plant filter system makes a significant contribution to environmental protection and improving air quality. These systems are designed and manufactured in compliance with environmental regulations and international standards. Controlling dust emissions is crucial for reducing harmful particles released into the environment and minimizing risks to worker health.

Advantages of the Alfamix Filter

The reverse flow system ensures zero air consumption and electricity savings.
The reverse flow system ensures easy maintenance and long-lasting operation. The electric actuators used in the reverse flow system have a power output of 0.18 kW and, unlike jet pulse and pneumatic reverse flow systems, do not require a compressor. Furthermore, since separate pneumatic pistons are not used for each chamber, there are no operating and maintenance costs.
Temperature control is achieved using two independent methods, including a PT100 and a heat thermostat, and the burner automatically shuts off when the set temperature is exceeded. This prevents filter fires.
An optional blower system can be added to the filter system to improve the cleaning quality of the filter bags. This ensures extra dust extraction and comfortable operation, especially in humid areas.
An optional fresh air damper can be added to the system. This damper’s function is to open the filter inlet to the atmosphere when excessive heat is detected in the filter, allowing the filter unit to cool quickly.
Since the filter body includes a cyclone section, a separate cyclone unit is not required.
Because our filter system includes a cyclone section, coarse and fine fillers are collected from separate compartments. A weighted damper or air lock (rotary valve) placed in these compartments ensures maximum filter efficiency.

Asphalt plant The filter system is an important piece of equipment for reducing harmful particles and gases released into the environment. These systems are designed and used in compliance with environmental regulations and standards. Proper operation of the filter system during asphalt production helps minimize environmental impacts.

The Asphalt plant filter and fan unit consists of a dirty gas channel, a clean gas channel, a fan intake adjustment flap, a filter unit, and a fan unit. The main function of the Asphalt plant filter and fan unit is to capture, filter, and release clean air from the dust and dirty gases generated in the system before they are released into the atmosphere.

At Alfamix Asphalt, we can produce two different types of Asphalt plant filter systems. These types are reverse flow system asphalt plant filter units and jet pulse type asphalt plant filter units. Both types of filter systems have their own pros and cons. As alfamix asphalt, we are always here to inform our customers on these issues so that you, our valued customers, can make the right decision. asphalt plant The main suction fan sucks in the polluting gas and aggregate dust generated during combustion in the asphalt plant dryer unit. It passes these through specially designed filter bags made of meta-aramid material with high dust-holding capacity and capable of operating at high temperatures. This filter extracts the dust from the asphalt plant dryer unit, the asphalt plant mixing unit, and the asphalt plant screening unit, ensuring the plant remains clean and production-friendly.

At Alfamix, we insulate our asphalt plant filter units using high-density insulation material to protect them from temperature fluctuations and maintain the existing temperature. A suction adjustment valve located in the asphalt plant fan group allows the asphalt plant to We operate the system using highly precise, proportional electric actuators to ensure the operator always controls the suction setting of the filter unit. We always choose high-technology products from global companies to produce high-quality, high-efficiency systems in our asphalt plant filter units. Thanks to the quiet operation of our fans, the design used in the asphalt plant fan unit not only eliminates dust pollution but also provides a solution to noise pollution thanks to its extremely quiet operation.
