Description
Technical field
The present invention relates to beam-type limekiln field, specifically a kind of steel and refractory materials composite adiabatic formula burning beam.
Background technology
The forties in last century beam-type limekiln invented by U.S. combinating carbide company UCC; the fifties, USSR (Union of Soviet Socialist Republics) started to adopt; adopted water cooling burning beam technology at that time; the sixties in last century, China carried out the test of the beam type kiln of water-cooling system protection burning beam at Taiyuan Iron and Steel Co.; but the working life of burning beam is shorter, thus do not have extensively to promote.The sixties in last century, Italian Terruzi Fercalx Group Te Luzifukasi company have purchased U.S. combinating carbide company technique, and develops the oil cooled burning beam of heat conduction and just worldwide promote.Eighties of last century China's nineties has introduced 300t/d, 400t/d, 500t/d beam type kiln in succession, and fuel is coal dust, coal gas, but does not pass a test due to its high expense and low calorie fuels and Pulverized Coal aspect and technology, makes it promote and receives very big restriction.After entering 21 century, domestic technique personnel are improved and are promoted gradually, therefore make this technology be extended and develop.Again afterwards, more domestic producers and technician have applied for Patents at home, and this kiln type has domestic independent intellectual property right, are renamed as " beam type kiln ".Beam type kiln is as a kind of gas-burning kiln on the world, domestic market, and the progress promoted generally is more sane.Aspect, world market is still dominated by gondola Fu Kasi company at present, according to investigation in September, 2013, the beam type kiln seat number that Fu Kasi company had already built up in Europe, America, Africa And Middle East Area and Chinese market reaches 275, and production capacity reaches 2,700 ten thousand tons.Aspect, domestic market controlled primarily of domestic beam type kiln supplier, and according to incomplete statistics, domestic beam type kiln sum of having built reaches 398, and the production capacity of already having gone into operation reaches 3,600 ten thousand tons.A number always built by whole world beam type kiln is 673, and aggregated capacity reaches 6,300 ten thousand tons.From quantity and production capacity, beam type kiln technology is that world's lime industry has made larger contribution.
Although promote in beam type kiln world wide very universal, the core that always annoying its technical progress is for many years exactly that the thermal losses problem of burning beam is never well solved.
At present, the burning beam on market does not nearly all adopt refractory materials, directly will be placed in the middle of flame with the oil cooled steel construction of heat conduction; In addition, major part adopts stainless steel lag screws or stainless steel supporting plate fixed outer refractory materials, and result life-span short and effect extreme difference, can not meet energy-saving and cost-reducing requirement; Some adopts the modes such as hook form, high temperature steel supporting form, high temperature steel and hook mixed form to fix refractory materials, it uses result mostly can not realize long lifetime operation, a few week will come off some months at least at most, can not normally run after causing installation.
Summary of the invention
The object of the present invention is to provide a kind of steel and refractory materials composite adiabatic formula burning beam, this heat-insulating burning beam solves the problem that closely cooperates of steel construction and refractory materials, improve the work-ing life of refractory materials, improve the degree of insulation of burning beam, overcome the fatal drawback that burning beam thermal losses is in the past large, achieve the revolutionary advancement of burning beam stuctures and properties.
For achieving the above object, the invention provides following technical scheme:
A kind of steel and refractory materials composite adiabatic formula burning beam, comprise steel construction, the side of described steel construction and bottom are provided with some burner holes, described steel construction inside is provided with thermal oil cooling system, steel construction outside is wrapped up by thermal insulation material, described thermal insulation material outside is wrapped up by refractory materials, and refractory materials is fixed on steel construction by refractory materials fixed mechanism, described refractory materials fixed mechanism inside is provided with thermal oil refrigeration cycle pipeline, and thermal oil refrigeration cycle pipeline and thermal oil cooling system form thermal oil cooling recirculation system; Thermal insulation material and refractory materials are stretched out in described burner hole.
As the further scheme of the present invention: the refractory materials at described steel construction top is provided with the anti-accumulation refractory materials of trilateral.
As the further scheme of the present invention: the external spray of described refractory materials fixed mechanism has refractory paint.
The present invention has enough rigidity to realize integrally-built stability in the integrally-built design of support; The design of steel construction part retains the structure formation of thermal oil circulating cooling system, and object keeps relatively high temperature in high temperature environments when burning beam, realizes relative temperature difference less, improve the working life of refractory materials; In addition, refractory materials fixed mechanism is also provided with thermal oil refrigeration cycle pipeline, and is connected with the thermal oil circulating cooling system of steel construction, refractory materials is protected, achieve the heat-insulating property of burning beam, and achieve the target of the stable of structure of refractory and long lifetime use; In addition, mesectoderm refractory materials of the present invention mainly plays and bears high-temperature calcination, intercepts thermal-flame and directly contacts with thermal insulation material; Internal layer thermal insulation material major function is that trap heat directly imports steel construction into, and the thermal oil to greatest extent in minimizing steel construction is directly to exterior conductive heat.
Compared with prior art, the invention has the beneficial effects as follows:
(1) technique calcining hear rate can reduce by more than 90%;
(2) refractory materials extends to more than 1 to 2 years work-ing life;
(3) the present invention can widely use beam-type limekiln and close industrial furnace aspect thereof, uses as burner, greatly can improve the life-span, reduce consumption.
