We usually use drainage equipment to capture and filter harmful emissions to maintain a safe working environment. The operation of these devices consumes energy, and some processes consume a lot of energy. Whether it is a small laboratory or a large factory, there are ways to reduce energy consumption by using drainage and filtration systems, especially when the drainage equipment does not need to run continuously. Here are some ways to reduce energy consumption in exhaust ventilation and filtration systems.
1. Use automatic damper for smoke and dust source exhaust
If possible, capturing harmful fumes, smoke and dust from pollution sources is the most energy efficient and efficient way to prevent them from reaching breathing areas or contaminating the environment. In addition, drain points should be opened only when needed and with appropriate air volume. A damper is the best way to control air flow. Because the operator generally does not strictly in accordance with the energy saving needs to close and open the manual throttle, but automatic throttle can control the throttle opening and closing according to the actual working state, so as to save a lot of energy consumption.
2. Optimize pipeline design to meet wind speed requirements
After the pollutant dust/soot is collected at the source, it will be transmitted from the collection point to the filtration equipment through pipes. Depending on the characteristics of dust, you need sufficient wind speed to avoid dust and particulate matter accumulation in the pipe. There may be more than one pumping point in a workshop, and pumping will not take place simultaneously. Even if the number of exhaust points changes, it is important to ensure sufficient wind speed at each exhaust point. By optimizing the size of the pipe and maintaining sufficient wind speed in the pipe, the system can save as much energy as possible.
3. Keep the pressure drop and resistance in the filter at low levels
After pipeline transportation, dusty air reaches the filter. As with piping, the air volume design of the filter should be appropriate to the number of exhaust points. In general, the total air volume of the filter design is less than the sum of all the exhaust point combinations. In order to filter effectively, the dust filter wind speed should not be too high, and should be designed reasonably. This keeps filtration resistance in the filter at a fairly low level, saving energy consumption and keeping the filter in good condition for a long time. In addition, it is very important to use appropriate filter materials for different dust characteristics. This makes the filter easier to clean, thus minimizing the number and frequency of cleaning. The compressed air used for cleaning will consume energy, and excessive cleaning will cause damage to the filter material. Filters are cleaned by an optimized compressed air automatic pulse system to ensure optimum operation of filters.
4. Use frequency conversion drive to optimize the energy consumption of the fan
The fan of the exhaust system has an impact on the above content, so reducing the energy consumption of the fan is also a very practical way. If the fan is always running at full speed regardless of the actual workload, more air is generated than is needed, resulting in wasted energy and wear to the filter. It is very important to adjust the fan running speed according to the actual working air volume demand to reduce energy consumption and cost.
Variable speed drive (VSD) with pressure control, also known as variable frequency drive (VFD) or inverter, helps control fan air volume changes. Thanks to VSD, the pressure of the pipeline system is controlled, and the operation speed of the fan can also be optimized according to the actual air volume needed to achieve the best dust removal capacity. In addition, optimal efficiency can be achieved by using a fan with backward-curved blades. All in all, these methods can help you better use and optimize your dust removal system, improve filtration performance, and reduce noise levels and energy costs.
Which method to use depends on your process and the intensity of your operation.
