Flue gas collecting device for discharging of calcium carbide furnace

The utility model discloses a flue gas collecting device for discharging of a calcium carbide furnace, which comprises a vertically arranged collecting hopper, a collecting barrel is coaxially and fixedly mounted at the bottom end of the collecting hopper, and a carbon felt heat-resistant device is coaxially mounted at the bottom end of the collecting barrel; the utility model has the beneficial effects that the structure is simple, the carbon felt heat-resisting device with excellent heat-resisting performance is designed at the bottom end of the collecting barrel body, the heat-resisting performance is improved, a good heat insulation function is realized, the bottom of the collecting barrel body is prevented from being burnt, the water-cooling pipeline is moved upwards, the excessive heating of the water-cooling pipeline is reduced, and the service life of the water-cooling pipeline is prolonged. And therefore, the anti-cracking water leakage device is worthy of being popularized and used in a large range.
