Abstract
The utility model provides an automatic protection device of blast furnace top pressure gas, belongs to the technical field of smelting, and specifically relates to an iron making blast furnace. The TRT (Top pressure Recovery Turbine) unit of the protection device is connected with a bleeding tower through a bleeding pipe, and a regulating valve bank is arranged on the bleeding pipe. The automatic protection device of blast furnace top pressure gas is characterized in that when the blast furnace top pressure rises suddenly, the regulating valve is quickly opened so that the gas flow is directly bled through the bleeding tower from the pipe without passing through the top pressure recovery turbine and entering a low-pressure gas main pipe network, and therefore, the potential safety hazard of gas leakage caused by breakdown of a gas drainer due to the impact on the top pressure recovery turbine unit and pressure rising and fluctuation of the low-pressure gas main pipe network is solved, and safe and steady operation of gas pipeline facilities is effectively guaranteed.
Description
Technical field
The utility model belongs to technical field of smelting, is specifically related to a kind of iron-smelting blast furnace.
Background technology
The coal gas that iron-smelting blast furnace produces is now through gravitational precipitator, nonaqueous dust cleaner, again through entrance butterfly valve, push-pull valve, cut valve soon and enter the turbine acting of expanding, the pressure energy that coal gas has and conversion of heat into kinetic energy drive generator generating, coal gas is discharged and is entered low-pressure gas pipe network from turbine, and TRT turbine power generation unit and pressure reducing valve of blast furnace group are in parallel.Blast furnace collapse material, collaborate under the abnormal conditions such as stream, blast furnace top pressure raises suddenly, air-flow directly impacts TRT generating turbine unit operation is brought to very large hidden danger; Air flow enters rapidly low-pressure gas supervisor net, makes the fluctuation that raises suddenly of low-pressure gas ductwork pressure, can cause pipe network hydathode to puncture the potential safety hazard of gas leak.
Summary of the invention
The purpose of this utility model is to provide a kind of blast furnace top pressure coal gas automatic-adjusting device, with solve prior art blast furnace collapse material, collaborate under the abnormal conditions such as stream, blast furnace top pressure raises suddenly, and air-flow directly impacts TRT generating turbine unit operation is brought to very large hidden danger; Air flow enters rapidly low-pressure gas supervisor net, makes the fluctuation that raises suddenly of low-pressure gas ductwork pressure, can cause pipe network hydathode to puncture the problems such as potential safety hazard of gas leak.
The utility model is mainly comprised of TRT unit, diffusing tower, decompression unit, fly-ash separator, solves technical scheme that its technical problem adopts and is TRT unit and connected variable valve group is set on diffusing tower, bleeder by bleeder.
Adopting positively effect of the present utility model is that this regulated valve is opened rapidly when blast furnace top pressure raises suddenly, this strand of air-flow directly from then on device for cleaning pipeline cross diffusing tower and directly diffuse, without turbine, do not enter low-pressure gas supervisor net to solve the existing potential safety hazard to the impact of TRT turbine and low-pressure gas ductwork pressure rising fluctuation coal gas drainer breakdown leakage coal gas yet, effectively guarantee the steady running of gas line installation security.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the utility model structural representation;
1TRT unit, 2 variable valve groups, 3 bleeders, 4 diffusing towers, 5 fly-ash separators, 6 reducing valve groups in figure.
Embodiment
As shown in the figure: TRT unit 1 is connected on diffusing tower 4, bleeder 6 variable valve group 2 is set by bleeder 3; The structure of TRT unit, diffusing tower, decompression unit, fly-ash separator is same as the prior art.
Claims (1)
1. a blast furnace top pressure coal gas automatic safety device, is mainly comprised of TRT unit, diffusing tower, decompression unit, fly-ash separator, it is characterized in that TRT unit is connected variable valve group is set on diffusing tower, bleeder by bleeder.
