Air purification system and control method thereof

Abstract

The invention relates to an air purification system comprising a air passage. An air inlet unit, a high-voltage electrostatic precipitation unit, a mist spray purification unit, and an air discharge unit are arranged along the air passage. The high-voltage electrostatic precipitation unit and the mist spray purification unit are arranged sequentially or in a reversed sequence. The invention also provides an air purification control method based on the air purification system. According to the invention, related devices in the air purification system are considered as a device layer, and a control layer and a control management layer are arranged. The device layer performs sensor and measuring instrument data acquisition and transmission, and performs driving and controlling over a variable frequency motor, a high-pressure controller and a solenoid valve. The control layer acquires information of related devices in the device layer, and controls the working statuses of the devices. The control management layer performs control and management upon the entire system. With the air purification system and the control method thereof, purification effect is good. The system and the method are energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to environmental management, in particular to an air purification system and a control method thereof. Background technique [0002] Existing air purification system is of a great variety, but the inventor of the present invention finds that there are still many deficiencies in its aspects: [0003] 1. For example, the air intake unit, the existing air intake unit usually has a single air inlet position in the space, and cannot enter the air from multiple points in all directions, which reduces the air intake efficiency. The air intake drive motor is mostly composed of a single variable frequency motor or a power frequency motor. In a time-delay, large inertia, and nonlinear system, there is only one way to adjust the air volume, wind pressure, and wind speed. In the case of no hot backup redundancy, once The failure of the main fan will affect the normal operation of the entire air purification system. [0004] The associated v...

[0003] 1. For example, the air intake unit, the existing air intake unit usually has a single air inlet position in the space, and cannot enter the air from multiple points in all directions, which reduces the air intake efficiency

The air intake drive motor is mostly composed of a single variable frequency motor or a power frequency motor. In a time-delay, large inertia, and nonlinear system, there is only one way to adjust the air volume, wind pressure, and wind speed. In the case of no hot backup redundancy, once The failure of the main fan will affect the normal operation of the entire air purification system

[0004] The associated variables of the set value of the air intake volume of the air intake unit are relatively simple, most of which are manual air intake on time and quantitatively, lack of automatic adjustment of air intake parameters on demand, and no variables such as air inlet air quality detection and air outlet air environmental quality detection feedback Participate in real-time control, the whole sy
