Analysis of water treatment industry
In the sewage treatment process, oil-free blower can provide clean and oil-free compressed air to meet the oxygen required for biodegradation, metabolism and chemical reactions. For example, the biological treatment unit in sewage treatment - activated sludge method, requires oxygen to maintain the growth and metabolism of microorganisms. By blowing air into the aeration tank or reaction tank, the blower provides oxygen, promotes the degradation of organic matter in the sewage and the removal of pollutants. The treated wastewater can be reused or discharged into domestic sewage pipes or natural waterways to help green, energy efficient and sustainable development.
But in the choice of blowers, the enterprise users always ignore several important cases, there will cause a large different from the actual effect and the expected. High energy consumption, poor reliability, poor adaptability and insufficient after-sales service are the four main problems facing the current blower equipment market.
The low-quality blower equipment with the poor performance often to make the problems under longer working operation, also the downtime and maintenance often increase the maintenance cost of users.
Advantages and structure of oil-free screw blower
Oil-free screw blowers usually consist of a housing, a main engine, a air end, an air filter, a silencer, and a control system. Its operating principle is to use two parallel male and female rotors to mesh with each other in the "∞" shaped cylinder to form a working volume. Through the synchronous gear, the rotor rotates at high speed in reverse, so that the working volume changes periodically with the rotor operation, so as to achieve the compression and transportation process of air.
Different from the traditional blower, oil-free screw blower achieves internal compression in the process of air transportation in the cavity, so the oil-free screw blower is more efficient than the traditional blower, and the process of air transportation and compression is continuous and gradual, the air pulsation is lower, the exhaust noise, temperature control and so on are better than the traditional blower.
Application of oil-free screw blower in water treatment
Oxygen system
Oxygen systems for wastewater treatment plants that promote the growth of aerobic microorganisms and the decomposition of organic matter by supplying oxygen to ponds or reactors. Oil-free screw blowers can provide a steady airflow to support these biological processes.
Air flotation system
In the water treatment process, air flotation systems are used to remove suspended solid particles or oils. Oil-free screw blowers can provide enough air pressure and air flow to help form small bubbles and promote the floating and separation of particles or grease.
Purge & wash system
During the filter and membrane separation process, the purge system uses gas to clean the filter medium to maintain its efficiency and longevity. Oil-free screw blowers provide a stable air flow for efficient filtration and separation.
Aeration system
During water treatment, sometimes need to inject a air (such as oxygen or carbon dioxide) into the water to regulate the dissolved oxygen or pH in the water. Oil-free screw blowers can precisely control the rate and amount of air injection to meet specific processing requirements.
