Rotary pulse water distributor: The device is composed of a drive motor, a pendulum reducer and a rotary valve, driven by a JZT solenoid valve speed motor, using a planetary cycloidal needle wheel reducer to rotate the valve spool, pressurized sewage is introduced into the rotating spool by the inlet pipe, through the valve water distribution gap into the water outlet chamber, and then the sewage is sent out by the outlet pipe, due to the water distribution The gap rotates with the spool, so there is only one outlet pipe at a certain time Water is sent to the water distribution point, and the water distribution cycle of the outlet pipe can be achieved by changing the number of revolutions of the motor. Application and scope of use of the device: The device is suitable for anaerobic fermentation and aerobic denitrification and denitrification treatment of high and medium concentration sewage in various industries (gold treatment, petroleum, chemical, printing and dyeing, textile, brewing, sugar, food, electricity). It solves the problems of uneven distribution of anaerobic and denitrified structures and sludge subsidence.: The main features of the installation are as follows: It can schedule sewage The fixed point is evenly distributed in the reaction structure, and the utilization rate of the structure is greatly improved. It accelerates the generation and growth of granular sludge in reaction structures. It allows sewage to not clog the reactor and inlet. The device is easy to operate, reliable in operation, simple in maintenance and convenient to manage. Equipment design: The seller is responsible for the selection and design of all equipment, piping materials, motors, and reducers in the complete equipment. The buyer is responsible for the utility engineering design, and the seller is responsible for providing the specifications, quantity, interface location, civil construction requirements, and electrical-related design materials of the supplied equipment.
