In the production of electric power, metallurgy and other industries, in order to remove the sulfur element in coal and prevent sulfur dioxide generated during combustion from entering the atmosphere and polluting the environment, flue gas desulfurization is usually used to collect the flue gas after combustion for desulfurization through the gypsum wet process. Blower in the flue gas desulfurization process mainly assume the role of air supply oxidation, to ensure that the blower in the process can provide sufficient oxygen, such as insufficient air volume will cause inadequate oxidation, resulting in low quality by-products, desulfurization is not complete, etc.
Product Description
The MSC series maglev centrifugal blower of "TOUZER" brand is a high-tech achievement formed by the patented technology of maglev bearing combined with fluid mechanics developed by the team of doctors from Dalian Polytechnic University, which has the characteristics of frictionless, high power saving rate and low noise, and is a high-end energy-saving equipment. The products are divided into 19 specifications according to different power (15kW~315kW), different wind pressure (25kpa~120kpa) and different air volume (13~430m³/min), and the impellers can also be designed according to different working conditions to meet customized requirements. MSC series maglev blowers have been widely used in urban sewage, industrial wastewater, electronic crystal plate, biopharmaceutical, smelting and coking, textile printing and dyeing, food fermentation, thermoelectricity and other industries in more than 30 provinces since they were put on the market in 2018. Compared with traditional blowers, maglev blowers save more than 30% energy. --Energy saving and high efficiency: integrated magnetic suspension bearing, high speed permanent magnet synchronous motor, high efficiency flow parts, special control system and a series of advanced technologies, high efficiency and energy saving of the whole machine.Compared with traditional Roots blower, the efficiency is increased by 30%~40%.Taking 160kW maglev blower as an example, each one can save more than 500,000 degrees of electricity per year compared with the traditional Roots blower, and the cost can be recovered in about 1 to 2 years.
--Low noise and vibration: Thanks to maglev bearing technology, there is no mechanical contact and friction between rotating parts and stationary parts in the fan. The vibration of the fan operation is very small, and the noise does not exceed 80 dB.
--Small size, light weight: The whole machine integrated design, internal integrated fluid components, motor, frequency converter and other components, compact structure, light weight.
--Intelligent operation and maintenance: The use of advanced control system, a variety of control modes can be selected. The operating platform can be monitored in real time without special person on site duty. Fully enclosed air cooling and water cooling systems are used to dissipate heat from the motor to ensure stable and efficient operation of the fan. Modular design, convenient maintenance.
--Very Low maintenance cost: Using magnetic bearing technology, completely frictionless. No gear box, lubrication system and other parts in the system, no mechanical maintenance, reduce the chance of damage, service life can reach more than 20 years. Daily maintenance only need to replace the air filter, save lubricating oil, cleaning costs, convenient and fast.

Installation Instructions
1. 1.8m of space should be left around the equipment to ensure normal work and daily maintenance.
2. Avoid strong shaking and collision in the process of equipment handling.
3.The equipment should be installed on a solid foundation with no vibration source around, and the adjustment of the footing should be matched with the level to keep the equipment parallel to the horizontal plane.
4. If the equipment is installed indoors, it is necessary to ensure the heat dissipation conditions in the machine room, and if it is installed outdoors, direct contact with rain and snow should be avoided.
5. Electrical installation should be done by licensed electrician.
6. The venting pipe is recommended to be led to outdoor, if it is indoors, it is easy to blow up the dust, which will affect the efficiency of the fan and the life of the filter, and avoid facing the direction of the personnel.
