Problems solved by technology
Due to the poor sealing effect of the old-fashioned CDQ high temperature compensator, it often leaks and burns through the bellows, making maintenance and replacement very inconvenient. Therefore, the CDQ high temperature compensator is required to have a longer service life. However, the current CDQ high temperature compensator Replacement is required if the service life of the device is less than 1 year

The invention discloses a dry-quenching rectangular metal high-temperature compensator, and relates to the technical field of high temperature compensators. The circumference of the inner wall of the compensator is uniformly welded with several long and short anchoring nails, the inside central part of the compensator is symmetrically provided with anchoring plates, the outer wall of a gap between the anchoring plates is welded with an inner guide cylinder, the outside of the inner guide cylinder is provided with an outer guide cylinder, the outside of the outer guide cylinder is provided with a corrugated tube, and a heat insulation material is arranged between the corrugated tube and the outer guide cylinder, the outer guide cylinder and the inner guide cylinder, and the inner guide cylinder and the anchoring plates. The compensator of the invention, which does not deform or delaminate when the temperature is above 800DEG C and adopts above maze structure to prevent the medium flee-around, has the advantages of good whole heatproof and wear-proof effects, good sealing effect, no power leakage, no wind fleeing, no ash deposit, and long service life.
Description
Technical field: [0001] The invention relates to the technical field of high temperature compensators, in particular to a CDQ rectangular metal high temperature compensator adopting a labyrinth structure. Background technique: [0002] The CDQ high-temperature compensator is installed in the outdoor high-altitude, at the connection between the primary dust collector and the CDQ furnace and boiler, where the flue gas has a large dust content and high heat radiation temperature. The circulating gas temperature is 880-960°C, and the instantaneous maximum temperature reaches 1100°C. Due to the poor sealing effect of the old-fashioned CDQ high temperature compensator, it often leaks and burns through the bellows, making maintenance and replacement very inconvenient. Therefore, the CDQ high temperature compensator is required to have a longer service life. However, the current CDQ high temperature compensator The device should be replaced if its service life is less than 1 year. ...
