Operation skills of Roots blower in sewage treatment

    With the acceleration of urbanization and population growth, a large amount of wastewater is discharged into the environment, which poses a serious threat to the ecological environment and public health. In order to protect the environment and improve the water quality, effective treatment of wastewater has become an urgent problem to be solved. As a common sewage treatment equipment, Roots blower plays an important role in it, and its operation skills are very important to improve the treatment efficiency and performance.


    Roots blower is a type of centrifugal blower with forward displacement. It is composed of two coaxial, meshing with each other, internal non-contact triangle rotor to complete the compression and transport of air. This structure enables Roots blowers to have high pressure ratios and flow characteristics, which are suitable for various wastewater treatment scenarios.


    For vibration problems, try to keep the blower away from the working area or isolation room, and set the muffler and anti-vibration measures reasonably. In addition, the air inlet and outlet of the blower also need to be rationally arranged to avoid airflow resistance and ensure normal airflow in and out.


    Secondly, the Roots blower needs regular maintenance and inspection during operation to ensure its long-term stable operation. Regularly check the clearance of the rotor and the wear degree of the bearing, and replace the wear parts in time to avoid affecting the performance of the blower. At the same time, the inside of the blower should be cleaned regularly to prevent the blockage of dirt and foreign matter leading to the abnormal operation of the blower.

    Thirdly, reasonable selection of the working parameters and working conditions of Roots blower is the key to improve its treatment of water quality. First of all, it is necessary to select the appropriate model and specification of Roots blower according to the actual situation to ensure that its output gas flow and pressure can meet the processing requirements. Then, according to the wastewater characteristics and treatment process requirements, the rotation speed and intake temperature of Roots blower are adjusted to optimize the operating efficiency and energy saving effect of the blower.


    In addition to operation skills, the selection and application of Roots blowers should also take into account some additional conditions. For example, because the sewage contains a lot of taste, toxic gases and corrosive substances, the corrosion resistance of the material should be taken into account when selecting Roots blowers, and the surface treatment or anti-corrosion coating should be added if necessary.
