A dust collecting device characterized in that an installed cylindrical body is arranged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cyclone-type dust collector that separates dust-like solid particles floating in the air by using centrifugal force. The dust collector of the present invention is used for separating solid particles such as ash, dust, and sawdust from dust-containing gas emitted from, for example, a pulverized coal-fired boiler, a cement rotary hook, and a woodworking machine.

[0002]

[Prior art]

 As a dust collector, a dust-containing gas inlet for introducing dust-containing gas into the case tangentially is provided in the upper part of a substantially conical case, and air from which solid particles have been removed is released into the atmosphere. A cyclone-type dust collector has already been used in which a discharge cylinder is attached and a solid particle dropping hole for dropping solid particles separated from dust-containing gas is provided at the lower end of the case.

In this dust collector, a dust-containing gas is introduced from a dust-containing gas inlet into a substantially conical case in a tangential direction and is rotated in the case so as to contain centrifugal force. The solid particles are separated from the dust gas, and the air from which the solid particles have been removed is discharged into the atmosphere from the air discharge cylinder at the top of the case, and the solid particles fall from the solid particle drop hole at the bottom of the case.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional dust collector, there is a problem that the air from which the solid particles have been removed makes a loud noise when passing through the air discharge tube in the upper part of the case. The present invention has been made to solve the above problems in the conventional dust collector.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a mesh body or a cylinder body having a large number of through holes formed on the inner surface of an air discharge cylinder in a dust collector.

That is, the present invention provides a dust-containing gas inlet for introducing dust-containing gas tangentially into the upper part of a substantially conical case and removing solid particles into the atmosphere. In a dust collector having an air discharge cylinder for discharging, and a solid particle dropping hole for dropping solid particles separated from dust-containing gas at the lower end of the case, a net cylinder is provided on the inner surface of the air discharge cylinder. The present invention provides a dust collecting device (claim 1) characterized by being provided with.

In addition, according to the present invention, a dust-containing gas introduction port for introducing dust-containing gas into the case tangentially is provided at the upper part of a substantially conical case, and air from which solid particles have been removed is introduced into the atmosphere. In a dust collector equipped with an air discharge cylinder for discharging, and a solid particle drop hole for dropping solid particles separated from dust-containing gas at the lower end of the case, a plurality of solid particles are provided on the inner surface of the air discharge cylinder. The present invention provides a dust collecting apparatus (Claim 2), characterized in that a cylindrical body having a through hole is arranged therein.

[0008]

[Action]

 In this dust collector, as in the above conventional dust collector, dust-containing gas is introduced tangentially from the dust-containing gas introduction port into a substantially conical case, and is rotated in the case. The solid particles are separated from the dust-containing gas using a centrifugal force, and the air from which the solid particles have been removed is discharged into the atmosphere from the air discharge cylinder at the top of the case, and the solid particles fall from the solid particle drop hole at the bottom of the case. To do.

In the dust collector according to the present invention, however, since the net cylinder or the cylindrical body having a large number of through holes is disposed on the inner surface of the air discharge cylinder, the dust collector near the inner surface of the air discharge cylinder is disposed. It hinders the smooth flow of air. As a result, no loud noise is generated when the air from which solid particles have been removed passes through the air discharge tube in the upper part of the case. Incidentally, in this case, a sufficient amount of air can be discharged from the air discharge cylinder by making the diameter of the air discharge cylinder slightly larger than that of the conventional one.

[0010]

【Example】

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 denotes a substantially conical case in the dust collector. A dust-containing gas inlet 3 for introducing dust-containing gas into the case 1 in a tangential direction is provided in the upper part of the case 1. Further, on the upper part of the case 1, an air discharge cylinder 5 for discharging the air from which solid particles are removed into the atmosphere is attached. Further, at the lower end of the case 1, a solid particle dropping hole 7 for dropping the solid particles separated from the dust-containing gas is provided. Reference numeral 9 is a roof to which a dust collector is attached.

Therefore, in the present invention, the mesh cylinder 11 or the cylinder body 15 having a large number of through holes 13, 13, ... Is disposed on the inner surface of the air discharge cylinder 5.

[0012]

[Effect of device]

 As described above, in the dust collector according to the present invention, since the mesh tube or the cylindrical body having a large number of through holes is arranged on the inner surface of the air discharge cylinder, the air from which the solid particles have been removed is removed. It is reliably prevented from making a loud noise when passing through the air discharge tube on the top of the case.
