Solid-liquid mixed oil-water separation device

Abstract

The invention relates to a solid-liquid mixed oil-water separation device. The device comprises a deslagging module, an oil-water separation module and a waste water storage module, the waste water storage module comprises a water storage tank and a water pump, the water pump is arranged at a water outlet of the water storage tank, the waste water storage module further comprises a frequency converter and a permanent magnet variable frequency motor, the water pump is connected with the permanent magnet variable frequency motor, and the frequency converter is connected with the permanent magnetvariable frequency motor. Compared with the prior art, the standby of the motor in a low-frequency state is realized by utilizing the sleep function of the frequency converter, so that the frequent starting of the motor is reduced, the mechanical vibration generated when the motor is started can be effectively reduced, and the stable operation of equipment is facilitated; and meanwhile, adverse effects on a power supply network when the device is started are reduced to the maximum extent.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a solid-liquid mixed oil-water separation device. Background technique [0002] Sustainable development is an important issue facing today's society. Resource conservation must increase energy use efficiency and be able to recycle and use energy in a sustainable manner. With the improvement of people's living standards, the total amount of domestic wastewater produced by people is increasing, and the sewage treatment plant will make water resources reusable through various processes and steps. The current sewage treatment uses solid-liquid mixed oil-water separation device to initially separate oil pollution, but the existing solid-liquid mixed oil-water separation device has the following problems: 1. Most of the existing devices use low-efficiency common-rate asynchronous motors, and their average Low efficiency, high energy consumption and low power utilization rate; 2. The st...

The current sewage treatment uses solid-liquid mixed oil-water separation device to initially separate oil pollution, but the existing solid-liquid mixed oil-water separation device has the following problems: 1. Most of the existing devices use low-efficiency common-rate asynchronous motors, and their average Low efficiency, high energy consumption, and low power utilization rate; 2. The motor is started using the direct power frequency control method, which has a large impact on the starting current, large noise pollution, frequent starts, and large pollution to the power supply network due to the impact of the starting current. , and the mechanical vibration shock when the motor starts is very unfavorable to the stable operation of the equipment
