Capacity type ventilated purification apparatus

Abstract

The invention discloses a ventilation and purification device which adopts a positive displacement blower, has a powerful air purification function, comprises an automatic cleaner for a filter, and is suitable for the ventilation and air purification of various buildings. The device comprises an air inlet, the blower, a filtering device, an air outlet, a controller, etc. The ventilation and purification device adopts the positive displacement blower to provide motive power for air flow, and has a steady air flow rate; a main filtering device adopts a ring-shaped band filter; one part of the band filter operates in an air filter state, and retention dirt in the other part is cleaned by a blowing device; and through the drive of an electric directive wheel, dynamic automatic cleaning of the filter is achieved.

Description

Technical field [0001] The invention relates to a ventilation and purification device, which adopts a volumetric fan to provide air flow power, and a ventilation and purification device with a dynamic automatic cleaning filter, which is suitable for ventilation and air purification of various buildings. Background technique [0002] Ventilation system is a common equipment in modern buildings, especially for large public buildings (such as commercial, exhibition, etc.), ventilation system has become a necessary equipment to ensure a high-quality environment inside the building. [0003] The known ventilation system is composed of a ventilation and purification device (main engine), air supply and return air ducts matched with the building, terminal air outlet and return air outlet, etc., and an appropriate evaporator (condenser) is usually arranged in the pipeline to realize air cooling. Temperature adjustment. The ventilation and purification device as the host mainly cons...

AI Technical Summary

Problems solved by technology

Among them: ①Centrifugal fan with large pressure head has high noise and relatively low efficiency, and the pressure head and air volume are greatly affected by the resistance of the airflow channel

②Low-resistance large-aperture thin mesh filter has poor air filtration effect, and the indoor air cleanliness index is low

Although the microporous dense filter layer has a good filtering effect on dust and bacteria, the air resistance is large, and the dust intercepted during filtering is continuously accumulated on the filter, which further increases the air resistance flowing through the filter, making the ventilation air volume Decrease, affecting the indoor ventilation effect

Therefore, the microporous dense filter layer is difficult to meet the requirements of the existing ventilation system for the low resistance of the filter

[0004] The main engine of the existing ventilation system is difficult to take into account practical technical indicators such as ventilation air volume, air purification capacity and fan efficiency (power consumption)
