Energy-efficient fan filter unit

Abstract

The invention relates to an energy-efficient fan filter unit, and belongs to the technical field of air purification equipment. The fan filter unit comprises a filter device and a high-efficiency filter detachably mounted at the bottom of the filter device, wherein the filter device comprises a shell; an air inlet is formed in the top of the shell; a fan unit is arranged at the position, located at an air outlet end of the air inlet, of the inner side of the shell; an electrostatic dust collection device used for adsorbing dust particles is arranged at the air outlet end of the fan unit; a dust removal device used for removing dust on the electrostatic dust collection device and recycling the dust is arranged in the shell; an air outlet is formed in the bottom of the shell; and the air outlet end of the high-efficiency filter faces the air outlet. The electrostatic dust collection device is additionally arranged in the filter device, and the electrostatic dust collection device can greatly reduce the dust content in air, so that the filtering effect can be further improved, the burden of the high-efficiency filter is reduced, and the service life of the high-efficiency filter is prolonged.

Description

technical field [0001] The present application relates to the field of air purification equipment, in particular to a high-energy-efficiency fan filter unit. Background technique [0002] The full name of FFU is Fan Filter Units, which means "fan filter unit" in Chinese. The fan filter unit is a ceiling unit with a built-in fan. It is used in turbulent flow and laminar flow clean rooms. The overall design of the unit is flexible. According to the design specifications , it can be easily matched with any ceiling frame to meet the requirements of cleanliness class 1000 to class 1. The fan filter unit is one of the quietest, well-priced units on the cleaning market. With this unit, high-quality air can be delivered to the clean room. [0003] The service life of the high-efficiency filter inside the fan filter unit is generally about two years. However, because the actual use environment of each enterprise is different, if the air quality in the area is poor and there is a lo...

Problems solved by technology

[0003] The service life of the high-efficiency filter inside the fan filter unit is generally about two years. However, because the actual use environment of each enterprise is different, if the air quality in the area is poor and there is a lot of dust in the air, the filter inside the fan filter unit Fans need to increase the exhaust air volume, resulting in an increase in fan energy consumption, which is contrary to the energy-saving and environmental protection concept of modern production. The fan filter unit is generally fixed on the top of the floor. When the high-efficiency filter needs to be replaced, the entire fan filter unit needs to be dismantled and installed after the replacement of the high-efficiency filter. This process is time-consuming and laborious.
