The refractory material layer is arranged on the water-cooling cavity of gasification chamber, the coal gas outlet pipe is arranged on upper part of the water-cooling cavity of gasification chamber, the upper air exit and the lower air exit of the gasification chamber are arranged on the right lower part of the water-cooling cavity of the gasification chamber, the slagoff hole is arranged on the lower part of gasification chamber water-cooling cavity, the precombustion chamber air-supply line, coal dust conveyer tube of precombustion chamber and the precombustion chamber bellows are arranged on the left lower part of gasification chamber water-cooling cavity. The utility model has scientific and novel concept, simple equipment, reliable operation, low cost price, economized coal, take full advantage of available resources, and realize high strength and high efficient aerification of coal dust in normal pressure and high temperatures conditions.
Description
Technical field: the utility model relates to the novel a kind of air flow bed coal dust gasification device that has burn-off chamber in the industrial gas stove industry.
Problems such as background technology: at present, the burning in the industrial gas stove industry both at home and abroad consumes a large amount of energy, and usually, coal gasification is based on fixed bed, fluidized-bed process, but exists gasification intensity little, and it is poor that coal is adapted to, and gasification efficiency is low; Pressurization dry-powder air-current bed process can address the above problem, but because the increase of vaporizer internal pressure, whole plant has brought the complicated of coal gasification apparatus to very strictness of the seal request high temperature (1400～1700 ℃) under, and problem such as cost an arm and a leg.Therefore develop a kind of air flow bed coal dust gasification device that has precombustion chamber is the scientific research task that expectation solves always.
The purpose of this utility model provide a kind ofly conceive the science novelty, technology is easy to manufacture, equipment is simple, cost is low, easy to operate, safeguard simple, overcome problem that existing air flow bed coal dust gasification technology exists, kept the following gasification characteristics of existing dry-powder air-current bed high temperature, a kind of air flow bed coal dust gasification device that has precombustion chamber of the high gasification intensity of realization and high gasification efficiency under normal pressure.
The utility model content: the purpose of this utility model is achieved in that whole device is by sealing cover, the gas exit pipeline, exhaust outlet on the vaporizer, exhaust outlet under the vaporizer, slag-drip opening, the precombustion chamber blast pipe, power transportation pipe, the precombustion chamber bellows, refractory masses, vaporizer water-cooled cavity is formed, in vaporizer water-cooled cavity, adorn refractory masses, the gas outlet conduit of coalingging on vaporizer water-cooled cavity top, exhaust outlet on the dress vaporizer of the right middle and lower part of vaporizer water-cooled cavity, exhaust outlet under the vaporizer, at vaporizer water-cooled cavity bottom dress slag-drip opening, at middle and lower part, vaporizer water-cooled cavity left side dress precombustion chamber blast pipe, the precombustion chamber power transportation pipe, the precombustion chamber bellows are at vaporizer waterway body dress sealing cover; For keeping the higher gasification temperature of vaporizer, increased precombustion chamber, because the temperature in it is up to 1200～1600 ℃, coal dust makes its rapidly experience preheating, expansion, pyrolysis devolatilization branch, but owing to the oxygen-rich air quantity not sufficient that enters by the precombustion chamber air port, coal dust can only carry out incomplete combustion; Unburned burnt grain and the gas that is produced are heated to 1200～1600 ℃, enter into vaporizer, under the vaporized chemical effect that upper and lower two exhaust outlets enter by vaporizer, for the helical movement, gas velocity can reach 20～40m/s, burnt grain mixes with vaporized chemical, and finishes gasification in 1～2 second.Main points of the present utility model are its structure and principle.Its principle of work is: coal dust is delivered to the precombustion chamber by power transportation pipe, at high temperature mix with the oxygen-rich air that enters by the precombustion chamber air port, the reaction of generation incomplete combustion, the high-temperature gas that it produced is being carried the burnt grain of red-hot not combustion secretly and is being entered into vaporizer, under the effect of vaporized chemical, the generating gasification reaction.Gasification temperature in the vaporizer is realized by the incomplete combustion degree of control precombustion chamber.Lime-ash after the gasification is the melting state under the vaporizer action of high temperature, be deposited to the bottom of vaporizer, discharges by slag-drip opening.The coal gas of high temperature that obtains moves up along vaporizer, enters into cooling section, to reduce gas temperature (not being higher than 1000 ℃), is discharged the subsequent disposal operation that enters coal gas at last by the gas exit pipeline.In the device of the present utility model, precombustion chamber and the gasification room temp up to more than 1400 ℃, so adopted the water cooling wall structure; Be not subjected to the erosion of pyritous gas what inwall adopted refractory masses with further protection water wall, can secularly move with assurance equipment.A kind of air flow bed coal dust gasification device that has precombustion chamber compared with prior art has design science novelty, technology is easy to manufacture, applied widely, equipment is simple, reliable, cost value is cheap, be sparing in the use of coal, make full use of existing resource, can realize being widely used in advantages such as coal dust high strength, high efficiency gasification in the industries such as the energy, chemical industry, boiler under normal pressure, high temperature.
