In the front end of sewage treatment Air suspension blower There is a lot of room for energy saving improvement, On March 5, 2024, the government work report of the two sessions focused on "new quality productivity" in the first point of the economic task arrangement in 2024, "vigorously promoting the construction of modern industrial system and accelerating the development of new quality productivity", which was consistent with the central economic work conference in December 2023, and pushed the attention of the concept of "new quality productivity" to a new high.
The sewage treatment industry is related to the national economy and the people's livelihood, and the demand is growing rapidly. Urban domestic sewage treatment has become the main source of the demand side of the sewage treatment industry. In 2022, the sewage discharge of cities and counties nationwide will be 75.39 billion cubic meters, an increase of 2.59% over 2021, including 63.897 billion cubic meters of urban sewage, accounting for 84.76%; Domestic sewage accounts for more than 60% of the total sewage discharge in China. Under such huge market demand, it is an inevitable choice for the water industry to superimpose double carbon pressure and improve new quality productivity.
In the front end of sewage treatment, the fan equipment used has a large space for energy saving and improvement, among which the air suspension fan and magnetic suspension fan have significant energy saving effects. In the early stage, it needs to invest a little more cost than the conventional fan, and can continue to create value later, which is mainly reflected in:
1. Good energy-saving effect: compared with old Roots fans and multi-stage centrifugal fans, the energy-saving effect of air suspension and magnetic suspension fans is more than 30%, which can continue to save energy;
2. Low noise and environmental protection: the suspension fan adopts suspension mechanical bearing or electrical bearing, which is free of friction in suspension, low noise, no need of lubricating oil, and more environmentally friendly;
3. Low maintenance cost: the suspension fan is simple in structure, unlike the traditional Roots fan, which is bulky and has many mechanical faults, and the maintenance cost is high; The suspension fan only needs to replace the filter cotton irregularly, so the maintenance cost is low;
4. Good economic benefits: invest in the suspension fan on the sewage and waste water production line, and the machine cost can be recovered in one to one and a half years, saving significant electricity;
Air suspension blower It can continuously provide energy conservation and is the representative of new quality productivity. After more than ten years of research and production, the air suspension fan and magnetic suspension fan manufactured by Leitz has become a blockbuster product on the market, and has also brought sustainable energy conservation effects to the vast water industry.
