Improved wet acetylene production device

The utility model relates to the technical field of acetylene generating devices, and discloses an improved wet acetylene production device. The improved wet acetylene production device comprises an acetylene generator, a plate chain conveyor, a cleaning tower and a stripping tower, wherein at least one discharge chute is fixedly arranged above the plate chain conveyor through a bracket; and a rod brake valve is fixedly arranged at the discharge end of the discharge chute. According to the improved wet acetylene production device, an acetylene gas is recovered from residue slurry generated by the acetylene generator, so that unit consumption of calcium carbide is lowered; the acetylene gas is recovered through a feeding device, so that the unit consumption of calcium carbide is lowered; the unit consumption of calcium carbide is lowered through a residue extractor; 37.7t calcium carbide is saved by wastewater reclamation all the year round; the unit consumption of calcium carbide is lowered only by generation and cleaning units; about 18543t calcium carbide, namely 60526.07t standard coal is saved all the year round according to the annual output of 700000t polyvinyl chloride resin; and water consumed by per t of PVC is 1.03M /t PVC, thus the energy consumption is greatly lowered, and the environmental requirements can be met.
