The invention provides a lightweight blast furnace gas pipeline system. The lightweight blast furnace gas pipeline system comprises an ascending pipeline assembly, a descending pipeline assembly and a dust removal pipeline assembly; wherein the bottom end of the ascending pipeline assembly is connected to the top of a blast furnace body, the top end of the descending pipeline assembly is connected with the top end of the ascending pipeline assembly, and the bottom end of the descending pipeline assembly is connected with the dust removal pipeline assembly; and moreover, a first blow-off valve is arranged at the top end of the ascending pipeline assembly, a feeding system is arranged above the blast furnace body, a feeding platform is arranged at the top of the feeding system, and a first blow-off platform of the first blow-off valve is combined to the feeding platform so as to reduce the total length of the ascending pipeline assembly and the descending pipeline assembly. By means of the lightweight blast furnace gas pipeline system, the problems that an existing blast furnace gas pipeline is long in total length and high in investment cost can be effectively solved.
Description
technical field [0001] The invention relates to the technical field of blast furnace equipment, and more specifically, relates to a lightweight blast furnace gas pipeline system. Background technique [0002] In recent years, my country's iron and steel has developed rapidly, and it is developing from a big iron and steel country to a strong iron and steel country. With the frequent introduction of steel industry policies, the large-scale blast furnace has become a development trend. [0003] A blast furnace is a smelting equipment such as figure 1 As shown, a traditional blast furnace includes a blast furnace body 8', a weighing tank 14' connected above the blast furnace body 8', a receiving hopper 17' connected above the weighing tank 14', and a hopper arranged above the receiving hopper 17'. The feeding belt 18', during use, transports raw materials to the receiving hopper 17' through the feeding belt 18', and the raw materials go through the hopper 17', the weighing tan...
