Closed sampling device for vinyl chloride converter

The utility model provides a vinyl chloride converter closed sampling device which comprises a conveying pipe, a converter fixedly connected to one end of the conveying pipe, an adsorber arranged at one end of the converter and connected with the converter through the conveying pipe, and a sampling port arranged at one end of the adsorber. The sampling port is connected with the adsorber through a conveying pipe, and the combined tower is arranged at one end of the sampling port. The utility model provides a closed sampling device for a vinyl chloride converter, which realizes closed sampling by transforming a sampling port of the converter in a conversion process of a vinyl chloride device, prevents poisonous and harmful gas from leaking, prevents waste gas generated by sampling from entering a combined tower, cancels an on-site absorption barrel, does not need to replace alkali liquor by inspection personnel, and improves the sampling efficiency. The risk of alkaline liquor burning is avoided, and the safet
