Abstract
The present invention relates to an energy-saving hot blast valve using little water, which solves the technical problem that valves of hot air pipelines can not be normally used, and the problem puzzles blast furnaces for a long time. The energy-saving hot blast valve comprises a valve body, a valve cover and a valve plate, wherein layered covering layers of a refractory liner are adopted in the valve body, a left large-flange casing and a right large-flange casing; a left large-flange sealing surface and a right large-flange sealing surface are arranged in water cooling pipelines; a layered covering layer of a refractory liner is also adopted in the casing of the valve cover. The symmetrical surfaces of an outer layer of a valve plate body adopt layered covering layers of a refractory liner, and the water cooling pipelines are distributed at the inner part. The layered covering layers of a refractory liner adopted by the valve body, the casing of the valve cover and the symmetrical surfaces comprise heat insulating layers, thermal insulation layers and high-temperature resistance layers. All the layers can respectively adopt refractory sticky casting materials of light weight and casting materials of heavy weight. The energy-saving hot blast valve using little water has the advantages of water saving, energy saving and obvious effect; the energy-saving hot blast valve using little water can meet the urgent needs of the present steel enterprises for water saving and energy saving. The water consumption of the energy-saving hot blast valve using little water is equivalent to 25 to 30% of that of hot blast valves of the same specification, the loss of wind temperature can be reduced, and the wind temperature can be enhanced by 10 to 20 DEG C. The energy-saving hot blast valve using little water can bear large heat shocks and thermal fluctuation, and the present invention can not be damaged by being frequently started; the service life of the present invention is.
Description
Affiliated technical field
The present invention relates to a kind of energy-saving hot blast valve using little water of blast-furnace hot-air pipe applications.
Background technology
Hot blast valve in the blast furnace ironmaking is installed on the hot air duct of hotblast stove, and long term operation is under hot environment, and working condition is abominable, and the thermal fatigue phenomenon takes place easily.For reducing its high temperature oxidation and thermal stress deformation, usually all be to adopt the water cycle type of cooling to lower the temperature both at home and abroad, though certain cooling-down effect is arranged, but water resources consumption is many, and the wind-warm syndrome loss is bigger, after incrustation scale appears in cooling water channel, water-cooled is obstructed, cause and can't lower the temperature, hot blast valve damages, and be very limited work-ing life.
Summary of the invention
In order to solve the technical barrier that above-mentioned long-term puzzlement blast-furnace hot-air pipeline valve can't normally use, intend improving the valve mechanism design, structurally adopt anti-high hot material lining, little in addition water cooling measure, but both water saving, can improve hot blast valve work-ing life again, thereby a kind of energy-saving hot blast valve using little water is provided.
The present invention solves the technical scheme that the prior art problem adopted:
Energy-saving hot blast valve using little water comprises valve body, valve gap and valve plate.Valve body and about adopt refractory liner tectum by different level in the big flange shell, about big flange sealing surface arrange water cooled pipeline.Also adopt refractory liner tectum by different level in the valve gap housing.Valve plate volume surrounding symmetrical surface all adopts refractory liner tectum by different level, the inner water cooled pipeline of laying.
The tectum of refractory liner by different level that valve body, valve gap and valve plate etc. are adopted comprises thermal insulation layer, thermofin and high temperature resistance layer, and thermal insulation layer adopts refractory felt, and thermofin adopts lightening casting material, and the high temperature resistance flame retardant coating adopts the heavy mould material.
Energy-saving hot blast valve using little water is economized on water, energy-saving effect is obvious, adapts to the water saving of present steel enterprise, energy-conservation pressing for.Its water consumption only is equivalent to 25～30% of the same specification hot blast valve water yield, and can reduce the wind-warm syndrome loss, can improve 10～20 ℃ of wind-warm syndrome on year-on-year basis, can bear big thermal shocking and heat fluctuation, and frequent starting is unlikely impaired, and prolong work-ing life.
