Embodiment 1

[0045] Figure 4 and Figure 5 A schematic structural diagram showing Embodiment 1 of the gas-solid cyclone separator of the present invention. In this embodiment, the lower end of the exhaust pipe is frusto-conical, and there is a feed inlet 1, which is a straight-cut inlet structure in which the feed inlet 1 and the cylinder body 3 are cut directly, and the cone 4 of the cyclone separator The wall of the ash hopper 8 is made of porous metal filter material. The outside of the cone 4 and the ash hopper 8 is surrounded and closed by the outer cylinder 7 to form a gas collection chamber 5. The outer cylinder 7 is in the same shape as the cone 4 and the ash hopper 8. The axis is arranged, and the middle part of the outer cylindrical body 7 has a filtered gas discharge port 6, which is used to discharge and / or draw out the filtered gas under negative pressure.

Embodiment 2

[0047] Figure 6 and Figure 7 A schematic structural diagram showing Embodiment 2 of the gas-solid cyclone separator of the present invention. In this embodiment, there are two feed inlets 1, which are double straight-cut inlet structures in which the two feed inlets are respectively cut directly with the cylinder body 3, and are used to increase the feed amount. The cone of the cyclone separator 4 and the walls of the ash hopper 8 are made of porous metal filter material, and the outside of the cone 4 and the ash hopper 8 is surrounded and closed by the outer cylinder 7 to form a gas collection chamber 5, and the outer cylinder 7 and the cone 4 and the ash hopper 8 form a The coaxial line is arranged, and the middle part of the outer cylinder body 7 has a filtered gas discharge port 6, which is used for discharging and / or extracting the filtered gas under negative pressure.

Embodiment 3

[0049] Figure 8 and Figure 9 A schematic structural diagram showing Embodiment 3 of the gas-solid cyclone separator of the present invention. In this embodiment, there is a feed port 1, which is a volute structure in which the feed port 1 is tangent to the cylinder body 3. Part of the cylinder body 3 of the cyclone separator is made of porous metal filter material, and part of the cylinder body 3 is surrounded and closed by the outer cylinder 7 to form the gas collection chamber 5, the outer cylinder 7 is arranged coaxially with the cylinder 3, and the middle part of the outer cylinder 7 has a filter gas discharge port 6 for discharging and / or negative air. The filtered gas is pumped out under pressure.

Abstract

The present invention relates to a gas solid cyclone separator. It includes the following several portions: cylinder body, cone body, ash bucket and gas-collecting chamber. It is characterized by that the wall of said ash bucket is made up by using porous metal filtering material. Said invention also provides the concrete working principle of said gas solid cyclone separator. Its separation effect can be up to above 99%.

Description

technical field [0001] The invention relates to a gas-solid cyclone separator, which relates to a cyclone separator for separating gas and solid particles in a mixture of gas and solid particles. Background technique [0002] The cyclone separator is widely used in chemical industry, metallurgy, pharmaceutical, environmental protection and other industries. It uses the centrifugal force generated when the gas-solid phase material with a certain flow rate rotates to separate the solid particles from the gas-solid phase material to achieve the purpose of gas-solid separation. . However, when the cyclone separator separates very fine particles or lighter particles with a relatively small density, these particles will be discharged from the exhaust pipe with the airflow, making the separation efficiency of the cyclone separator drop sharply. In the field of petrochemical industry, when purifying flammable and toxic gases that cannot be discharged, separating fine particles or l...
