The lower part of the gas water seal box is connected with a cleaning pipeline, and the cleaning pipeline is connected with a drainage sampling tube through a flange.
Specifically, the head of the drainage sampling tube is connected with a drainage pipe or a gas sampler.
Specifically, the diameter of the cleaning pipeline is larger than that of the drainage sampling pipe.
The utility model has the following beneficial effects:
the device for cleaning and preventing poisoning of the gas seal for the converter gas overcomes the defects that the gas seal is cleaned, water cannot be drained and the flange at the bottom of the four chambers of the water seal is detached, can effectively realize convenient water drainage, is convenient to operate, prevents early warning and reduces the labor intensity of staff;
the device overcomes the difficulty that operators have to detach the flange in the water seal water drainage and gas detection sampling process, and detects and samples after water is drained by the device before cleaning, so that gas poisoning accidents can not be caused in the water seal flange water drainage and sampling process, the intrinsic safety of equipment is realized, and the safety of operators is ensured.
