Chinese patent document 201620115410.5 discloses an indoor air purification system, which comprises an air inlet channel and an air outlet channel respectively communicated with indoor and outdoor, wherein the air inlet channel and the air outlet channel are respectively communicated with two fluid inlets of a heat exchanger, and an induced draft fan or a blower is arranged in the air inlet channel and the air outlet channel; a filtering device and a humidifier are arranged in the air inlet channel, and the filtering device comprises a filter screen, an electrostatic dust collector, an ultraviolet lamp, an HEPA filter and a photoion generator; and a filtering device is arranged in the air outlet channel. The utility model discloses an indoor air purification system has air inlet and air-out function, can introduce outdoor fresh air and handle, discharge indoor dirty air, improve indoor environment. However, the indoor air purification system is not effective in removing gaseous pollutants, such as formaldehyde, organic acids, etc., which are difficult to remove. The air purification system of the invention adopts adsorption purification, and can effectively remove gaseous pollutants. In addition, the system driven by the mechanical fan has larger vibration and noise, the mechanical fan and the air pipe are difficult to integrate, and the system is very difficult to compact due to the structural limitation, the uniformity of air flow transportation is poor, and the energy efficiency of the air flow transportation process is very low.
Chinese patent document 201510811961.5 discloses a solid-state fan coupled semiconductor constant-temperature and constant-humidity cultural relic display cabinet, which comprises a cabinet body, a constant-temperature and constant-humidity unit and a gas transmission unit, wherein the gas transmission unit is used for circulating gas in the cabinet body and constant-temperature and constant-humidity gas generated by the constant-temperature and constant-humidity unit, and comprises an air pipe connecting the cabinet body and the constant-temperature and constant-humidity unit, a first solid-state fan providing gas circulation power and a driving power supply; the gas transmission device of the invention adopts the solid fan to realize the accelerated flow of gas through the ionic wind, can provide power for gas transmission, overcomes the problems of noise and vibration, difficult adjustment of air quantity, poor uniformity, low energy efficiency of gas flow transmission and the like of the traditional mechanical fan, and has the advantages of good uniformity, no noise and vibration, convenient control and the like.

The mechanical fan driven medium and large air purification system is not beneficial to fully utilizing the purifying agent because the flow equalizing device needs to be arranged at the joint of the air pipe and the adsorption purification device due to the increase of the diameter of the single air pipe, otherwise, the fluid speed and the air flow at the center of the purification device are larger than those at the edge.
