Description
Technical field
The utility model relates to 40,000 tons of hard (carbon) black combustion units of a kind of annual output.
Background technology
Current domestic 40,000 tons of hard (carbon) black combustion units of annual output, as shown in Figure 1, it mainly will be comprised of air gas mixing section body skin 1 and 7 liang of large parts of combustor outer casing body; Flange is respectively equipped with in air and gas mixer body skin 1 front and back, forward flange is connected with stove face plate, six gas inlet pipes 2 are installed at stove face plate center, and rear flange docks with combustor outer casing 7 flanges, and air and gas mixer top is connected to high temperature air inlet pipe 3, air commutating plate 4, combustor outer casing is cast with refractory materials 5, and its principle of work is: high temperature air is from air intlet pipe 3, through air commutating plate 4, mix with the coal gas of gas inlet pipe 2, enter combustion chamber 6 burnings.Soot formation is mainly that the heat that more than 1900 ℃ high temperature gas flows provide producing by burning coke-oven gas completes, therefore combustion efficacy and the quality of studying coal gas are most important to production of carbon black, gas-fired high temperature gas flow temperature distribution is more even, generate particle size carbon black distribution just more even, the quality of carbon black products is also just better.
Summary of the invention
The purpose of this utility model is to be to provide a kind of annual output 40000 tons of hard (carbon) black combustion units, and this device one is to make gas-fired high temperature gas flow temperature distribution more even, the 2nd, and make the more abundant perfect combustion of coal gas, thereby improve the efficiency of combustion of coal gas.
The utility model is achieved like this, 40,000 tons of hard (carbon) black combustion units of a kind of annual output, it is mainly comprised of air rectification chamber, air and gas mixer, combustion chamber three parts, air rectification chamber comprises air intlet pipe and air rectifying tube, and air and gas mixer comprises gas inlet pipe, gas allocation chamber, mixing section and coal gas inlet hole; It is characterized in that: air intlet pipe connects air rectifying tube, air rectifying tube connects mixing section, and gas inlet pipe connects gas allocation chamber, and connects mixing section by coal gas inlet hole, and mixing section connects combustion chamber.
Air intlet pipe described in the utility model all becomes with refractory material casting to air rectifying tube and the enclosure interior that contacts with air, to reduce the heat lost by radiation of the high temperature air of 600-850 ℃, the combustion efficacy of favourable raising coal gas.
The effect of mixing section described in the utility model is by air and the more full and uniform mixing of coal gas, to produce the key that high-temp combustion gas flow temperature is evenly distributed, flange is respectively equipped with in mixing section body skin rear and front end, mixing section inner housing is formed by refractory material casting, annular pour mass periphery is provided with some row's coal gas inlet holes, each row's coal gas inlet hole angle is different, to guarantee that coal gas is covered with whole rounded section.
Principle of work of the present utility model is: the high temperature air of 600-850 ℃, through air rectification chamber, radial air stream is become to axial air flow, enter mixing section, coal gas enters gas distributor from gas inlet pipe, again by the some row's coal gas of annular pour mass circumference inlet hole, with different angles, enter mixing section, mix with the abundant preheating of axial high temperature air, enter combustion chambers burn, produce 1900 ℃ of above high temperature hot gas streams, for production of carbon black.
Than 40,000 tons of hard (carbon) black combustion units of former annual output, technique effect of the present utility model is: 1, former background technology air gas is mixed into integral body, and be not provided with attemperator, high-temperature gas heat lost by radiation, loss of energy, high temperature also brings hidden danger to operator simultaneously, and the utility model technology is all incubated high temperature air inlet pipe, rectifying tube, mixing section with lagging material, the thermal losses reducing, simultaneously favourable raising gas-fired speed.
2, former background technology air rectifier and air gas are blended in a device and carry out simultaneously, and air rectification effect is not good, due to from top to bottom mass force effect of radial air, easily make combustion heat air-flow depart from central axis; And the utility model technology is mixed air rectification and air gas and is divided into two devices, air is after rectifier, then by one section of rectifier straight-line segment, then by mixing tank front end straight-line segment, it is more excellent that footpath aweather becomes the effect of axial wind.
3, to mix with coal gas be that radial air mixes with 6 axial inlet coal gas to former background technology air, and background technology is axial air flow, with n gas aperture of several rows, in a few row's different angles rotation incision axial airs, air is more even with mixing of coal gas, more fully burning, thus greatly improved gas combustion efficiency, the utility model technology and background technology combustion unit can be saved coal gas 2-5%, and energy-saving effect is obvious.
4, the utility model technology is due to the rectification effect of air, and air and coal gas mixed effect splendid, make gas-fired, high-temperature fuel gas stream temperature is even, and high temperature gas flow can be in trunnion central zone, make production of carbon black reaction be in best region, thereby improve the inner quality of carbon black products.
