Background technique

In the existing air purification system, film-coated filter material is used for filtration, which can reduce the emission of ultrafine dust to a certain extent, but the filter material has certain limitations. Such as alumina, silicon carbide, etc.), the coating will be worn and damaged in a short period of time, losing the function of the coating, and failing to achieve the expected goal, and the existing purification system is aimed at the filtration of PM2.5 The purification effect is poor, causing certain pollution to the indoor environment, affecting people's indoor life and health.

Contents of the invention

The technical problem to be solved by the present invention is to provide an air dust removal and purification system, which is suitable for PM2. Dust, especially PM2.5, also has the wear resistance of the fiber structure, avoiding the problem of enhanced dust penetration and reduced filtration performance of the film-coated filter material due to film damage, so as to solve the problems existing in the above-mentioned prior art question.

The technical solution adopted by the present invention is: an air dust removal and purification system, including a delivery pipe installed indoors, one end of the delivery pipe is connected to the outside, the other end is connected to the room, the delivery pipe is connected to a suction fan, and the delivery pipe is connected to the indoor end. There is a filtering device, which includes a skeleton and a coarse fiber layer, a base cloth layer and a fine fiber layer arranged on the skeleton from the inside to the outside in sequence, and the surface layer of the fine fiber layer is covered with a fine fiber surface layer made of superfine fibers.

Preferably, the above-mentioned frame is fixedly connected to the delivery pipe through a boss on the edge, and the boss is fixed by screws.

Preferably, the above-mentioned conveying pipe is arranged in a circle along the indoor roof, and is provided with a plurality of openings, and filtering devices are arranged at the openings.

Beneficial effects of the present invention: compared with the prior art, the air purification system of the present invention has a good purification effect, and the fine fiber layer is covered with a fine filter material surface layer made of ultrafine fibers, and the fine filter material surface layer is composed of Made of spunlace, the fine surface layer has the function of a membrane, which can not only reduce the filter resistance of the filter bag, but also effectively capture ultra-fine dust, especially PM2.5. The wear resistance of the filter material avoids the problem of enhanced dust penetration and reduced filtration performance of the film-coated filter material due to membrane damage. The invention improves air purification and filtration efficiency, especially the filtration efficiency of ultrafine dust, and realizes The goal of better protecting people's indoor living environment has good promotion value and use value.

detailed description

The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

Embodiment 1: As shown in Fig. 1-Fig. 3, a kind of air dedusting purification system comprises the hollow conveying pipe 1 installed in indoor 3, one end of conveying pipe 1 is connected to the outside world, the other end is connected to indoor 3, and fixed Connected to the top of the room, the conveying pipe 1 is connected to the suction fan 2, and the upper suction fan is fixedly connected to the outside of the indoor wall. The end of the conveying pipe 1 connected to the indoor 3 is provided with a filter device 4. The filter device 4 includes a skeleton 5 and is sequentially arranged inside the skeleton 5. The outer thick fiber layer 6, base cloth layer 7 and fine fiber layer 8 are covered with a fine fiber surface layer 9 made of ultrafine fibers on the surface of the fine fiber layer 8, and the ultrafine fibers are used as the filter material of the fine fiber surface layer , due to its extremely fine fineness and larger specific surface area, it can more effectively capture dust particles as small as a few microns, and at the same time, its fiber structure can provide better wear resistance.

The filter material of the fine fiber surface layer is processed by spunlace. The filter material processed by spunlace method can reduce the damage to the fiber itself without destroying the original characteristics and characteristics of the fiber. The filter material of the fine fiber surface layer is made of 2 denier Denier's fine fibers are formed by high-pressure water crushing, which is a deep-processed product of fine fibers.

Preferably, the skeleton 3 is fixedly connected to the delivery pipe 1 through a boss on the edge, and the boss is fixed by screws.

Preferably, the above-mentioned conveying pipe 1 is arranged in a circle along the roof of the room 1 , and is provided with a plurality of openings, and a filtering device 4 is provided at the openings.

During use, the coarse fibers in the coarse fiber layer 1 mainly act as a support for the filter material, and the base cloth in the base cloth layer 2 acts as a steel skeleton, and the dust-laden smoke penetrates into the filter material from the surface layer of the filter material. The fibers of the fiber surface filter material are small and dense, and the large particles of dust are directly filtered on the surface of the ultra-fine surface layer. Part of the initial ultra-fine dust along with the flue gas penetrates into the gap of the fine fiber surface filter material, and is trapped by the ultra-fine fiber. As time goes on, more ultra-fine particles are trapped in the gap of the ultra-fine surface layer filter material and fixed for a long time. Due to the joint action of the fixed particles and the ultra-fine surface layer filter material, more and finer particles are retained. , Realize the improvement of purification and filtration efficiency; very few particles penetrate the fine fiber surface layer and are intercepted by the fine fiber surface layer.

The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present invention. Should be covered within the protection scope of the present invention, therefore, the protection scope of the present invention should be based on the protection scope of the claims.
