Abstract
The utility model relates to the field of air supply or air charging devices, and in particular relates to a hot air valve simulation device for a blast furnace hot blast stove. The hot air valve simulation device for the blast furnace hot blast stove comprises a shell (1) and a flame retardant layer (2), wherein the middle part of the shell (1) runs through; and the flame retardant layer (2) is built on the inner side of the shell (1) by using flame retardant bricks. The hot air valve simulation device is characterized by further comprising a water inlet (31), a water outlet (32) and a water-cooling pipeline (4), wherein the water inlet (31) is fixed at the opening in the bottom of the shell (1); the water outlet (32) is fixed at the opening in the top part of the shell (1); the water-cooling pipeline (4) is a helix pipe; the water-cooling pipeline (4) is wound on the inner wall of the flame retardant layer (2); and two ends of the water-cooling pipeline (4) are respectively connected with the water inlet (31) and the water outlet (32). The hot air valve simulation device is simple in structure, convenient to use, wide in application range and long in service life.
Description
Technical field
The utility model relates to ventilation or inflation mechanism field, is specially a kind of hot blast valve simulator for blast funnace hot blast stove.
Background technology
Hot blast valve is one of visual plant of blast-furnace hot-air furnace system, is used for controlling hot-blast stove gas burner and the cut-out equipment that opens and closes of pipeline on air.When hot blast valve need be changed or keep in repair, it was installed on the heating duct to need that then corresponding equipment replacement is arranged, to reach the effect to hotblast stove insulation, sealing.Traditional hot blast valve alternate device is made up of steel construction piece and anti-material, and often there are shortcomings such as resistance to elevated temperatures is poor, stopping property is not strong in this simple machine, if the hot blast valve alternate device damages, then can affect to hotblast stove.
The utility model content
In order to overcome the defective of prior art, provide a kind of blast furnace simple in structure, easy to use, applied widely, long service life to use and ventilate or inflation mechanism, the utility model discloses a kind of hot blast valve simulator for blast funnace hot blast stove.
The utility model reaches goal of the invention by following technical solution:
A kind of hot blast valve simulator for blast funnace hot blast stove, comprise housing and flame retardant coating, the housing middle part connects, housing is the structural part that adopts Q235 and Q345B stainless steel to make, the inboard of housing is built flame retardant coating by laying bricks or stones with refractory brick, it is characterized in that: also comprise water-in, water outlet and water cooled pipeline, water-in is fixed on the opening part of housing bottom, water outlet is fixed on the opening part of case top, water cooled pipeline is spiral element, on the inwall of water cooled pipeline coiling flame retardant coating, the two ends of water cooled pipeline connect water-in and water outlet respectively.
Described hot blast valve simulator for blast funnace hot blast stove is characterized in that: water-in adopts welding or flange to be fixed on the opening part of housing bottom, and water outlet adopts welding or flange to be fixed on the opening part of case top.
When the utility model uses; the utility model is substituted hot blast valve connect hotblast stove; water cooled pipeline is by the continuous water flowing cooling of water-in; water coolant is discharged by water outlet subsequently; working temperature is 900 ℃～1350 ℃; operating pressure is 0.1MPa～0.5MPa, has so just played and has isolated high temperature with the effect of protection hotblast stove.
The beneficial effects of the utility model are: simple in structure, easy to use, applied widely, and long service life.Adapt to the working temperature height, the life-span is long.
