Problems solved by technology

2: During boiler maintenance, gas maintenance, and shutdown, U-shaped tube water seals must be used to isolate blast furnace gas
Although this technology realizes the early warning function of gas pressure roof fall, it is not perfect, and it does not eliminate the damage caused by high gas pressure to the water seal, nor does it have the function of replenishing water in time
[0007] For example, the application number is: 201320633988.6, and the patent titled "A Automatic Cleaning Device for Converter Gas Water Seal" mainly uses cylinders and other pneumatic components to drive the scraper to simply clean the water seal cylinder online, manual control, and component comparison Single and not highly automated

Description

technical field [0001] The invention relates to a blockage removal device, in particular to an online blockage removal device for quick replenishment of gas water seals and drainage cylinders, and belongs to the technical field of electric instrument machinery. Background technique [0002] The principle of the gas water seal is a device that uses the static pressure of water to prevent the flow of gas. The pressure generated by water at a certain depth can seal the gas below the pressure. The function of blast furnace gas water seal in Meishan Iron and Steel Thermal Power Plant is 1: When the boiler is in normal operation and uses blast furnace gas, the U-shaped tube water seal is used as a blast furnace gas trap to discharge water and other condensate in the gas pipeline without letting the gas in the pipeline escape. 2: During boiler maintenance, gas maintenance, and shutdown, U-shaped tube water seals must be used to isolate blast furnace gas. [0003] The current appli...
