Embodiment Construction

[0020] The present invention provides a solution for a large air volume purification fresh air machine with a hollow fiber membrane as the main filter material, and its specific implementation will be disclosed in more detail through an example below. However, this does not limit the further scope covered by the spirit of the claims of the present invention.

[0021] The cabinet (5) is a casing made of sheet metal.

[0022] The air inlet assembly (1) can be a square or circular flange joint structure, and its caliber should be compatible with the design air volume of the whole machine; the pre-filter assembly (2) is installed in the air inlet assembly Among (1), it can be composed of interception net, coarse filter net and medium-efficiency filter net, or one or two of them. The pre-filtration technology itself is a mature technology in the fresh air treatment industry, but it is not a new technology for the fresh air filter device with hollow fiber membrane as the main filte...

Abstract

The invention relates to a high-wind-quantity purification fresh air machine using a hollow fibrous membrane as a main filtering material. The fresh air machine consists of parts such as a machine cabinet, an air inlet assembly, a front filtering material assembly, a membrane assembly array cabin, a membrane assembly, a confluence branch pipe box, a confluence sound insulation and attenuation cabin, a fan motor unit, a fan motor sound insulation and attenuation cabin, a roundabout air outlet hole passage, an air outlet sound attenuation cabin and an air outlet. The multistage sound insulation and attenuation cabin chamber is used, so that the noise problem of the high-wind-quantity purification fresh air machine is solved. Over ten thousands of cubic meter of clean fresh air can be provided. As the hollow fibrous membrane, particularly a polytetrafluoroethylene hollow fibrous membrane is used as the main filtering material, great dust containing capacity is realized and the maintenance and operation cost can be greatly reduced.

Description

technical field [0001] Large air volume purification fresh air fan with hollow fiber membrane as the main filter material. Background technique [0002] Hollow fiber membranes were mainly used in water treatment in the past. In recent years, hollow fiber membranes, especially polytetrafluoroethylene hollow fiber membranes, have gradually begun to be used as air filtration materials for air purification, and some designs and products have emerged, such as CN201610688301.7, CN201610188265.8, CN201320046259.0, CN201520825582.7, CN201420625143.7 and other patents. [0003] However, these designs are all for small air volume models. For public buildings, large air volume models are needed. How to use hollow fiber membranes as the main filter material to manufacture large-scale air purification devices, the industry only has large-scale water treatment technology And the experience and technology of complete sets of equipment, there is no plan to use hollow fiber membranes to dea...
