Description

Technical Field

[0001] The utility model relates to the technical field of anti-static electricity, in particular to an anti-static electricity device for a synthetic gas compressor. Background Art

[0002] At present, electrical corrosion has occurred in the bearings of all levels of synthetic gas compressors. The Babbitt alloy on the surface of the bearings is in a silvery-white corrosion state. Compared with new bearings, the surface roughness is significantly higher, and there are pitting on the wear surface of varying sizes.

[0003] The main reason for the electrical corrosion of the bearing is that during the operation of the unit, the power steam condenses into small water droplets, which generate static electricity on the high-speed rotating blades. Because there is no anti-static device, the static electricity cannot be conducted into the ground. The static electricity will accumulate more and more on the rotor. When it reaches a certain level, it will break through the oil film between the bearing and the journal, causing spark discharge. After each spark discharge, a tiny pit will be left on the discharge surface. As the discharge continues, countless small pits will appear on the discharge surface, forming electrical corrosion.

[0004] Therefore, there is an urgent need to provide an anti-static device for a synthesis gas compressor, which, compared with the prior art, can eliminate or prevent static electricity generated during the operation of the unit, avoid damage to the bearing caused by electrical corrosion, increase the service life of the bearing, and stabilize the operation of the unit.

[0027] The carbon brush assembly includes a brush handle 1, a brush head 2, a connecting shell 3, bristles 4 and a wire 5. One end of the brush handle 1 is fixedly connected to the brush head 2. Both the brush handle 1 and the brush head 2 are hollow structures. The outer diameter of the brush handle 1 is larger than the outer diameter of the brush head 2. The end of the brush head 2 away from the brush handle 1 can be detachably connected to the connecting shell 3. The connecting shell 3 is sleeved on the end of the brush head 2. The connecting shell 3 is connected to the brush head 2 by bolts. A plurality of bristles 4 are welded inside the connecting shell 3. The wire 5 passes through the brush head 2 and the brush handle 1. One end of the wire 5 contacts the bristles 4. The other end of the wire 5 passes through the end of the brush handle 1 away from the brush head 2 and is grounded. The bristles 4 are made of carbon alloy and are conductive carbon alloy wires. A plurality of bristles 4 are arranged perpendicular to the axis of the brush head 2. The end of the bristles 4 away from the connecting shell 3 contacts the outer wall of the rotor 8.

In the process of the fixed block 7 driving the carbon brush assembly to move in the sliding groove 61, the bristles 4 are always in contact with the outer wall of the rotor 8, and the rotation angle range of the carbon brush assembly is ±45°.
