Converter system with circulating pump

The utility model discloses a converter system with circulating pump, including the circulating pump, the pump intake of circulating pump and the tower cauldron of converter intercommunication, the circulating pump pump mouthful with the tower of converter in communicate, the bottom of converter is provided with the acetylene air inlet. The utility model discloses simple structure under the prerequisite that does not change original process consideration, had both reduced acetylene consumption, had improved the output of product again, when process that the acetylene gas upwards flows touchesthe mixed liquid of downward flow, had strengthened the resistance of acetylene gas, had reduced the mobile speed of acetylene, had lengthened the contact time of acetylene with methyl alcohol, and littleer bubble can be cut apart to become with the acetylene bubble by the resistance that mixes the production of liquid stream measured time simultaneously, has increased the area of contact of acetylene and methyl alcohol,
