Description

Comb-shaped plate structure of superheater tube

Technical Field

The utility model relates to an superheater pipe technical field specifically is a comb shape plate structure of superheater pipe.

Background

The boiler is ensured to run safely for a long time and is always the target pursued by all power plants, the comb-shaped plate structure adopted by the boiler superheaters of a plurality of power plants at present is used for preventing the superheater tubes from shaking through the comb-shaped plates, the comb-shaped plates are hung at the bends of the superheater tubes in the conventional installation mode at present and are in direct contact with the superheater tubes, the relative movement of the comb-shaped plates and the superheater tubes can be caused due to the disturbance of flue gas during the running of the boiler and the disturbance generated by the periodic work of a soot blower, the accumulated dust, coking and the like of the boiler, and the hardness of the comb-shaped plates is far greater than that of the superheater tubes at high temperature, so that the wear and the thinning of the superheater tubes are caused by the relative movement, thereby generating potential safety hazards.

Disclosure of Invention

In order to solve the problem that current comb plate causes the damage to the superheater pipe easily, the utility model provides a comb shape plate structure of superheater pipe, it can prevent effectively that comb plate from causing wearing and tearing, attenuate to overheated organ, ensures the long-term safe operation of superheater.

The technical scheme is as follows: a comb plate structure of a superheater tube, which comprises a superheater tube and a comb plate, characterized in that a tube clamp is mounted on the superheater tube, the tube clamp is supported on a bracket welded on the superheater tube at both ends, and the comb plate is hung on the tube clamp.

The device is further characterized in that the comb plates are arranged in at least two rows, three to five superheater tubes are arranged between two adjacent rows at intervals, and each row of comb plates is formed by the comb plates arranged at intervals.

Adopt the utility model discloses afterwards, realize the spacing of superheater pipe through pipe clamp cooperation comb plate and only shake to comb plate and superheater pipe part are direct contact not, can avoid the wearing and tearing of superheater pipe, have eliminated the potential safety hazard, have ensured the long-term safe operation of superheater.

FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;

fig. 3 is a cross-sectional view taken along line B-B of fig. 1.

Detailed Description

Referring to fig. 1 to 3, a comb plate structure of a superheater tube comprises a superheater tube 1, wherein a tube clamp 2 is mounted on the superheater tube 1, the tube clamp 2 is positioned above an elbow of the superheater tube 1, the outer wall of the superheater tube 1 is wrapped but not welded, the bottom of the tube clamp 2 is supported by a bracket 4 welded on the superheater tube 1 at two ends, the bracket 4 is fixed, so that the tube clamp 2 is fixedly supported, then the comb plate 3 is hung on the tube clamp 2, the opening of the comb plate 3 corresponds to the size of the tube clamp 2, the comb plate is in clearance fit without welding, and the limiting and shaking prevention of the superheater tube 1 are realized.

The comb plates 3 are arranged in four rows and four superheater tubes 1 are arranged between two adjacent rows at intervals, and each row of comb plates 3 is composed of four comb plates 3 arranged at intervals.

Claims

1. A comb plate structure of a superheater tube comprising a superheater tube and a comb plate, characterized in that a tube clamp is mounted on the superheater tube, the tube clamp is supported on a bracket welded on both ends of the superheater tube, and the comb plate is suspended on the tube clamp.

2. The comb plate structure of a superheater tube as claimed in claim 1, wherein said comb plate is arranged in at least two rows and three to five superheater tubes are spaced between two adjacent rows, each row of said comb plate is formed by said comb plates which are spaced apart.
