Technical Field

[0001] The utility model relates to the field of environmental protection, in particular to a coal dust separation and gas particle filtering device. Background Art

[0002] A large amount of coal dust is generated during the coal addition process of the gasifier. Usually, the coal dust is first introduced into the coal dust cyclone separator through an ejector. The large particles of coal dust are recovered through the discharge pipeline at the bottom of the cyclone separator, and the separated gas is discharged through the vent pipe. However, small particles of coal dust will be carried out together during the gas discharge process, resulting in poor emission indicators and causing pollution to the environment.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "top", "bottom", "one side", "the other side", "front", "back", "middle", "inside", "top", "bottom end", etc., indicating positions or positional relationships, are based on the positions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, unless otherwise expressly specified or limited, the terms "mounted", "connected", and "connected" should be understood in a broad sense, for example, they can mean fixed connection, detachable connection, or integral connection; they can mean mechanical connection or electrical connection; they can mean direct connection, indirect connection through an intermediate medium, or internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] like Figure 1 Figure 2 As shown, the utility model provides a coal dust separation gas particulate matter filtering device, including an ejector 1, a coal dust collector 2, a coal dust separator 3, a gas inlet pipe 4, a filtering device 5, a dust removal bag 511, a bag bracket 512, a horizontal pipe 513, a slide rail 514, a handle 515, a gas baffle 516, a particulate matter collector 517, a nitrogen inlet 518, a gas vent pipe 6, a nitrogen pipe 7, and a valve 8.

[0022] The ejector 1 introduces the coal dust into the coal dust separator 3 for separation. After separation, large particles of coal dust fall into the coal dust collector 2 at the lower end of the coal dust separator 3. The smoke gas carrying small particles enters the filter device 5 from the upper end of the coal dust separator 3 through the gas inlet pipe 4. The dust removal bag 511 filters the small particles of coal dust in the smoke gas, and the filtered gas is discharged into the air through the gas vent pipe 6.

[0023] When the dust bag 511 needs to be backflushed and cleaned, the dust bag 511 is pulled out of the gas vent pipe 6 by pulling the handle 515, and the valve 8 is opened. Nitrogen is blown through the dust bag 511, and small particles attached to the surface of the dust bag 511 fall into the particle collector 517.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0025] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
