Description
Technical field
The utility model is a kind of device blast furnace and hot blast cupola combustion valve being carried out to air leak test, belongs to blast funnace hot blast stove test set technical field.
Background technology
Blast furnace is in smelting process, and the impurity of a part of blast furnace raw material enters gaspipe network with blast furnace gas, and hotblast stove is when using pipe network coal gas to burn stove, and the impurity part in blast furnace gas is deposited in combustion valve valve seat, and a part sticks on the valve plate of combustion valve.The effect of combustion valve is that combustion valve is opened when hot blast stove burning, and coal gas enters hotblast stove combustion, and during hotblast stove air-supply, combustion valve is in the closed position, seals the hot blast in hotblast stove, cuts off with gas line.If the impurity sticked in combustion valve is too much, combustion valve will be caused poorly sealed, make hotblast stove when blowing, in stove, hot blast leaks from combustion valve and enters branch gas tube, gas stop valve before combustion valve be not closed completely leakage gas, will mix at hotblast stove branch gas tube, form explosive mixed gas, very likely gas explosion accident occur.Traditional inspection method, is all generally post operation personnel on site spot check, listens pipeline with or without the sound that leaks out, or touches pipeline sensible temperature.The main drawback one that this traditional method exists is labor intensive material resources, and two is that when post personnel are few or the changing-over stove frequency increases, on-the-spot spot check easily occurs undetected or leaks situation about finding not in time.Therefore, how can leak out by Timeliness coverage combustion valve fast, accident of stopping occurs, and becomes and ensures problem demanding prompt solution in safety in production.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of device Combustion of Hot Air Furnace valve being carried out to air leak test, whether this proofing unit can detect combustion valve quickly and easily and leak out, to find combustion valve fault rapidly, processed in time, stopped the generation of gas explosion accident.
The technical scheme solved the problems of the technologies described above is:
A kind of device Combustion of Hot Air Furnace valve being carried out to air leak test; it comprises base, sleeve pipe, thermometric hot resistance, tin hat; base is welded on the outer wall of the coal gas short tube outside combustion valve; base there is the inspection window perpendicular to coal gas short tube tube wall; the tube wall of coal gas short tube has perforate be connected with the inspection window of base, sleeve pipe is connected with base upper end, and thermometric hot resistance is placed in sleeve pipe; tin hat is sleeved on the rear end of sleeve pipe, and thermometric hot resistance is connected with hotblast stove PLC template by wire.
Above-mentioned device Combustion of Hot Air Furnace valve being carried out to air leak test, the front end of described sleeve pipe for being threaded, the tube wall of sleeve pipe has top wire hole with base upper end, and thermometric hot resistance is fixed in sleeve pipe through top wire hole by jackscrew.
The beneficial effects of the utility model are:
The utility model is arranged on the coal gas short tube outside combustion valve, thermometric hot resistance can detect the temperature in the coal gas short tube outside combustion valve, in hotblast stove punching course, leak out if combustion valve is not closed tight, temperature outside combustion valve in coal gas short tube will rise, the temperature measurement signal of thermometric hot resistance will remind operator's combustion valve to there is air leakage phenomena, so that operator process combustion valve fault in time, avoids the generation of gas explosion accident.The utility model structure is simple, and install and use all very convenient, Detection results is reliable and stable, can replace traditional manual detection method, effectively ensures the safety of producing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: hotblast stove 1, combustion valve 2, gas stop valve 3, coal gas short tube 4, coal gas diffusion pipe 5, base 6, sleeve pipe 7, thermometric hot resistance 8, tin hat 9, inspection window 10, top wire hole 11, jackscrew 12.
Embodiment
The utility model is made up of base 6, sleeve pipe 7, thermometric hot resistance 8, tin hat 9, jackscrew 12.
Show in figure, base 6 is welded on the outer wall of the coal gas short tube 4 outside combustion valve, base 6 has the inspection window 10 perpendicular to coal gas short tube 4 tube wall, the tube wall of coal gas short tube 4 has perforate be connected with the inspection window 10 of base 6, the warm air in coal gas short tube 4 can enter in inspection window 10.
Show in figure, the front end of sleeve pipe 7 is with base 6 upper end for being threaded, and thermometric hot resistance 8 is placed in sleeve pipe 7, and thermometric hot resistance 8 is connected with hotblast stove PLC template by wire, is transported in the operation room of hotblast stove by temperature measurement signal.Tin hat 9 is sleeved on the rear end of sleeve pipe 7, needs to turn on tin hat 9 when placing and take out thermometric hot resistance 8.
Show in figure, the tube wall of sleeve pipe 7 has top wire hole 11, thermometric hot resistance 8 is fixed in sleeve pipe 7 through top wire hole 11 by jackscrew 12.
The model of the thermometric hot resistance 8 of an embodiment of the present utility model is WZP-240PT100.
Working process of the present utility model is as follows:
Before at hotblast stove 1, by burning, stove transfers air-supply to, combustion valve 2 is closed, if combustion valve 2 is not closed tight and leaked out in hotblast stove 1 punching course, the temperature outside combustion valve 2 in coal gas short tube 4 will rise.Warm air enters in sleeve pipe 7 by the inspection window 10 be connected with coal gas short tube 4, and the thermometric hot resistance 8 in sleeve pipe 7 will be transferred to master control room by temperature signal, and prompting master control room operator, combustion valve 2 exists the phenomenon do not closed tight.If constant temperature rises, operator stop this hotblast stove 1 to run immediately, check processing after blowing out.
