Abstract
The utility model discloses a water-cooled tongue plate belonging to the technical field of a U-shaped material-returning device of a circulating fluid bed furnace, which comprises a left and a right tongue plates which are laterally symmetric, a water-cooling sleeve inlet collecting heater, cooling pipes, and a pin shaft which connects the left tongue plate and the right tongue plate, wherein grooves and through-holes are correspondingly arranged on the left tongue plate and the right tongue plate, the cooling pipes are located in the grooves, the upper ends of the cooling pipes are communicated with a downcomer, the lower ends of the cooling pipes are communicated with the water-cooled sleeve inlet collecting heater, and the pin shaft is traversed through the through-holes. For keeping the high-temperature stability between the connection of the left tongue plate and the right tongue plate, and the pin shaft connects the left tongue plate and the right tongue plate through adopting a welding mode. The water-cooled tongue plate has obvious beneficial effects, wherein a plurality of the cooling pipes are arranged inside the plate, water from the downcomer flows the inner of the plate and is continuously cooled, then flows to a water-cooled sleeve on the lower portion of the cyclone separator, and enters a drum for the next circulation, which reduces the high-temperature crackle of the tongue plate and prolongs the service life of the tongue plate.
Description
Technical field
The utility model belongs to CFBB U-shaped material returning device technical field, the hyoplastron that especially a kind of U-shaped material returning device is used.
Background technology
Hyoplastron is the dividing plate between material returning device material ascent stage and descending branch, and it can improve the self-locking airway dysfunction of material returning device, prevents from that pyrotechnics from returning to scurry.In the utility model patent application a few days ago, the hyoplastron that CFBB U-shaped material returning device of the prior art uses adopts the heat resisting cast steel manufacturing, no cooling device, because cast steel itself at high temperature easily produces micro-crack, hyoplastron was lost efficacy and damage, influence the returning charge of boiler, and then influence the normal operation of boiler, severe patient also can cause boiler out of service.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of water with Natural Circulation to make it can not damage distortion by Yin Gaowen to its cooling, thus the water-cooled hyoplastron that prolongs its service life.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of water-cooled hyoplastron, by symmetrical left hyoplastron, right hyoplastron, water collar inlet header case, cooling tube, left hyoplastron is formed with the bearing pin that right hyoplastron is connected, corresponding groove and the through hole of being provided with on a left side hyoplastron and the right hyoplastron, described cooling tube is arranged in above-mentioned groove, the upper end of cooling tube is connected with down-comer, and the lower end of cooling tube is connected with water collar inlet header case; Bearing pin penetrates in the through hole.
In order to make being connected between left hyoplastron and the right hyoplastron keep high-temperature stability, described bearing pin is connected left hyoplastron with right hyoplastron employing welding manner.
The beneficial effect of the utility model water-cooled hyoplastron is conspicuous, its inside is provided with some cooling tubes, from the current of down-comer in it to its continuous cooling, flow to the water collar of cyclone separator bottom then, enter drum again, enter next circulation, reduced the heat cracking of hyoplastron, prolonged the service life of hyoplastron.
