Problems solved by technology

The disadvantages of this technology are: it can remove floating dust (cannot remove poisonous gas), the efficiency is lower and slower than the mechanical type, and it is easy to generate ozone. This model is rated as the worst purifier by the US market
The disadvantage of this technology is: ordinary activated carbon can not absorb all toxic gases, the efficiency is low, and it is easy to desorb.
But there are still technical problems of inefficiency

Embodiment 1

[0053] This embodiment provides a method for purifying air and removing fine particles, such as Figure 9 As shown: the air to be cleaned in the rectangular purified air introduction pipe (1) enters the cylindrical shell (2) supported by the outrigger (3) and the base plate (4) at a wind speed of 10 m / s, and is then driven by a small synchronous wheel (21) After the filter membrane (12) on the outer surface of the filter cartridge (11) that drives the large synchronous wheel (22) to rotate at a speed of 0.5m / s is filtered, the filtered and purified air (300) is passed through the filter cartridge (11) The flow out of the end face enters the purification air conditioner, and after temperature and humidity adjustment, it flows back to the purification workshop. The fine particles (200) adhered to the filter membrane (12) are sucked out by the brush (5) and the negative pressure pump (44) in the dust collection mechanism (6), and enter the storage tank (45), and the fine particle...

Embodiment 21

[0076] This embodiment provides a device for purifying air and removing fine particles. The difference from Embodiment 1 is that the diameter of the filter cartridge is 1.5 meters.

[0077] In this embodiment, the treatment capacity of the air to be purified is 10000 m³ / min.

Embodiment 22

[0079] This embodiment provides a device for purifying air and removing fine particles. The difference from Embodiment 1 is that the diameter of the filter cartridge is 2 meters.

Abstract

The invention discloses a process and equipment for purifying air and removing fine particles. A rotary filter cartridge is adopted to improve the filtering efficiency. The filter cartridge adopts reverse filtration and reverse rotation processes, and air to be purified enters the filter cartridge from the outside of the circumference of the filter cartridge through a filter membrane and then is discharged through a pipeline, so that the air to be purified is filtered. Fine particles in the air to be purified are uniformly attached to the outer surface of the filter membrane, sucked out by a strip brush dust collection mechanism, filtered by a small filtering barrel and then discharged. The treatment capacity of the equipment is 5000m<3> / min or above, the equipment is industrial air treatment and purification equipment, fine particles in air purified by a purification chamber can be automatically filtered, the replacement frequency and cost of three-stage filtration of a purification air conditioner are reduced, and the purpose of filtering and purifying the air is achieved.

Description

technical field [0001] The invention belongs to the field of air purification in a purification workshop in the production process of medical equipment, and in particular relates to a method and a device for purifying air and removing fine particles. Background technique [0002] The production process of medical devices requires a clean environment of more than 100,000 grades. In the production process of medical devices, some fine particles will be produced in the production process of the purification workshop. The existence of these fine particles will reduce the purification level of the purification workshop. Contaminated medical device products. The current treatment methods for removing fine particles in the purified air are: Figure 10 As shown, the air to be purified passes through the three-stage filter screen of the purification air-conditioning system to isolate and purify the fine particles in the air, and then send it back to the clean room. [0003] The prim...
