Description

A reducing diameter spiral dust removal channel based on the principle of cyclone separation

technical field

The invention relates to the technical field of purification and dust removal, in particular to a diameter-reducing spiral dust removal channel based on the principle of cyclone separation.

Background technique

The structure of the existing dust removal equipment based on cyclone separation is usually various forms of cyclone cones, and its core structure is that the airflow channel rotates around the central cylinder, thereby generating centrifugal force to separate the dust; its structure is complex, and the air flow conditions are complex. , it is easy to produce strong turbulent flow, and the pressure drop loss is large. The dust removal efficiency of the existing single-stage dust removal device is not high enough, and in the two-stage and multi-stage dust removal methods, the airflow in the dust removal device often produces a great pressure drop loss. Therefore, how to propose a dust removal device with a simple structure, high dust removal efficiency, no turbulence during the dust removal process, and reduced air pressure drop loss is an urgent need for those skilled in the art.

SUMMARY OF THE INVENTION

In view of this, the main purpose of the present invention is to provide a diameter-reduced spiral dust removal channel based on the principle of cyclone separation, which has a simple structure, can effectively separate dust in the airflow, and has low pressure drop loss.

In order to achieve the above purpose, the present invention provides a diameter-reducing spiral dust removal channel based on the principle of cyclone separation, including a spiral channel. A plurality of dust collecting accessories are arranged at intervals on the outer arc of the channel; the dust collecting accessories and the spiral channel are communicated with each other through an opening.

Further, the cross section of the spiral channel is one of square, circular, triangular and trapezoidal.

Further, each section of the spiral channel is the same.

Further, the radius of the spiral channel starts from the airflow inlet, and the radius corresponding to the arc segment of the spiral channel decreases once every π radian, which can also be larger or smaller than π, such as π/3 or 3π/2.

Further, the helical channels are preferably located on the same plane, and may also have appropriate height changes.

Further, the radian occupied by the opening is π/60-π/3.

Further, the dust collecting accessory is detachably connected to the spiral channel.

The present invention has the following beneficial effects:

The channel of the invention adopts a spiral design and is divided into three sections of spiral channels. In the first arc section, the air flow separates the large dust particles in the air flow into the dust collecting accessories when it passes through the first dust removal port due to the centrifugal force. The arc radius of the second arc segment and the third arc segment is reduced, while the cross section of the spiral channel remains unchanged, so that the centrifugal force generated by the dust particles in the air flow becomes larger and larger, so that the smaller particles in the dust enter the second arc in turn. In the dust collecting accessories of the circular arc section and the third circular arc section, through multi-stage dust removal, the present invention can achieve relatively high dust removal efficiency; the spiral channel has a simple structure, and the pressure loss of the air flow during the movement process is reduced. And it is easy to achieve multiple dust removal and the pressure drop loss is very small, and achieve a relatively high dust removal efficiency. The invention has the advantages of simple structure, low manufacturing and maintenance costs, and very low noise pollution.

Detailed ways

In order to achieve the above objects and effects, the technical means and structures adopted in the present invention will be described in detail with reference to the accompanying drawings with regard to the features and functions of the preferred embodiments of the present invention.

As shown in Figs. 1-5, the present invention provides a diameter-reduced spiral dust removal channel based on the principle of cyclone separation, including a spiral channel 20, the outer end of the spiral channel 20 is provided with an airflow inlet 10, and the inner end is provided with a The air outlet 30; the outer arc of the spiral channel 20 is provided with a first dust collecting accessory 40, a second dust collecting accessory 41 and a third dust collecting accessory 42; A dust collecting port 21 is communicated, the second dust collecting attachment 41 is communicated with the spiral channel 20 through the second dust collecting port 22 , and the third dust collecting accessory 42 and the spiral channel 20 are communicated through the third dust collecting port 23 . The dust-laden airflow enters from the airflow inlet 10 and flows in the spiral channel 20 to generate centrifugal force. Under the action of the centrifugal force, the dust will gradually approach the outside of the spiral channel 20 in the radial direction. When the dust-laden airflow passes through the first dust collection port 21, the quality and Dust with large particle size flies into the first dust collecting attachment 40; after the air flow is purified once, it will continue to move along the spiral channel 20; as the radius of the spiral channel 20 gradually decreases, the centrifugal force generated will be stronger and stronger, which can The finer dust particles are separated in the second dust collecting port 22 and the third dust collecting port 23 .

In another embodiment, the cross section of the spiral channel 20 may be square, circular, triangular, trapezoidal or other polygonal shapes.

In another embodiment, the cross section of the spiral channel 20 is the same everywhere.

In another embodiment, the radius of the spiral channel 20 starts from the airflow inlet 10, and the radius corresponding to the arc segment of the spiral channel 20 is reduced once every π radian, which can also be larger or smaller than π, such as π/3 or 3π/2, The radius of each arc segment on the spiral channel 20 is shown in Figure 4, R1>R2>R3; the first arc segment is provided with a first dust collecting accessory 40, and the second arc segment is provided with a second dust collecting accessory 41. A third dust collecting accessory 42 is arranged on the third arc segment. Since the radius of the arc of the spiral channel 20 is gradually reduced, the centrifugal force generated will be stronger and stronger, and finer dust particles can be separated from the second dust collecting attachment 41 and the third dust collecting attachment 42 .

In another embodiment, the helical channels 20 preferably lie on the same plane.

In another embodiment, the spiral channel 20 is a spiral upward or downward spiral channel. It can be adjusted according to the actual situation.
