Abstract
The utility model relates to a magnesium calcium brick tunnel cave. Burning till of this magnesium calcium brick tunnel cave has a plurality of kiln car positions, and the kiln car position is used for placing the kiln car, and all there are two combustor nozzles the both sides of every kiln car position, and two combustor nozzle height of homonymy are the same, not homonymy combustor nozzle crisscross distribution from top to bottom, and the arbitrary front and back kiln car position combustor of the combustor of a plurality of kiln car positions interlocks about every survey of clinkering zone all becomes and distributes. Adopt crisscross distribution of high velocity burner multiple spot and careful block method to replace traditional tunnel cave clinkering zone both sides nozzle symmetric distribution or crisscross distribution on the coplanar, take the hyperbolic sealed fine solution such as the sealed design of friction in the clinkering zone kiln about the big problem of the difference in temperature.
Description
Technical field
This utility model relates to a kind of magnesia-calcium brick tunnel cave.
Background technology
Magnesite-dolomite refractories is a kind of basic refractory, has high temperature resistance, the good characteristic that alkali resistance corrodes, and does not result in environmental pollution, is the refractory material of a kind of environmental protection. During magnesite-dolomite refractories is produced by the substantial amounts of volume being applied to rustless steel and clean steel, can the impurity such as Al, S, P in the molten steel of effective place to go, play the purpose purifying molten steel. Magnesia-calcium brick tunnel cave is a kind of burning equipment in magnesia-calcium brick production process.
Tunnel cave upper and lower temperature difference is greatly use enterprise's common problem, and magnesia-calcium brick firing range is narrower, and sintering zone of tunnel furnace upper and lower temperature difference is big, easily cause top burning, the situation of bottom underburnt, not only affects the product quality of magnesia-calcium brick, has an effect on sintering qualified rate.
Tunnel cave upper and lower temperature difference is greatly due to stratification of hot gas in tunnel cave, and kiln car heat-insulation layer is inadequate, and kiln car song envelope is poorly sealed, and the factor such as cause kiln car radiation loss excessive causes. By reasonably piling up neatly brick mode (upper tightly lower sparse), and adjust want in pressure, can somewhat improve the temperature difference in some kilns, but the problem that can not thoroughly solve excessive temperature differentials.
Summary of the invention
Technical problem to be solved in the utility model is: how to solve the problem that sintering zone of tunnel furnace upper and lower temperature difference is big.
This utility model be the technical scheme is that a kind of magnesia-calcium brick tunnel cave, this magnesia-calcium brick tunnel cave burn till with multiple kiln car positions, kiln car position is used for placing kiln car, there are two combustor nozzles the both sides of each kiln car position, two combustor nozzle height of homonymy are identical, homonymy combustor nozzle is not interspersed up and down, the burner of multiple kiln car positions arbitrarily before and after kiln car position burner all become in the often survey of clinkering zone and be interspersed up and down.
As a kind of optimal way: kiln wall song envelope in clinkering zone both sides seals into hyperbolic envelope with kiln car both sides kiln car song, clinkering zone both sides kiln wall song envelope and kiln car contact surface are planar friction song envelope.
The beneficial effects of the utility model are: adopt high velocity burner multiple spot to be interspersed and careful group technology replaces conventional tunnel kiln clinkering zone both sides burner symmetrical at grade or is interspersed; Take hyperbolic to seal friction sealed design etc. and well solve the problem that in clinkering zone kiln, upper and lower temperature difference is big, it is desirable to effect can reach, within upper and lower temperature difference 5 degree.To obtain good result of use.

Detailed description of the invention
As shown in figures 1 and 3, a kind of magnesia-calcium brick tunnel cave, this magnesia-calcium brick tunnel cave burn till with multiple kiln car positions, kiln car position is used for placing kiln car, equipped with magnesia-calcium brick on kiln car, there are two combustor nozzles the both sides of each kiln car position, have 4 sprays to do, two combustor nozzle height of homonymy are identical, homonymy combustor nozzle is not interspersed up and down, the burner of multiple kiln car positions arbitrarily before and after kiln car position burner all become in the often survey of clinkering zone and be interspersed up and down, namely clinkering zone homonymy burner nozzle occurs in pairs by kiln car position, adjacent parking stall interlocks up and down, it is distributed in wave, each kiln car position burner nozzle from kiln car both sides up and down to blowing, the air-flow that rotate upwardly and downwardly is integrally formed, effectively stir evenly upper and lower temperature difference in kiln.
Kiln wall song envelope is that kiln wall coordinates, with kiln car, the face contacted, kiln car song seals the concavo-convex contact surface coordinated for kiln car with kiln wall, kiln car contact surface is that kiln car song envelope is following seals flat contact surface with kiln wall song, clinkering zone both sides kiln wall song envelope seals into hyperbolic envelope with kiln car both sides kiln car song, and clinkering zone both sides kiln wall song envelope and kiln car contact surface are planar friction song envelope. From figure 2 it can be seen that the left kiln wall song of kiln wall seals into male-female-convex-flat contact surface on the left of kiln car position, the left kiln car song of corresponding kiln car seals into concave-convex-recessed contact surface, and corresponding kiln car contact surface is flat contact surface, similar with kiln car contact site on the right side of kiln wall. Kiln wall song envelope uses hard high-alumina brick, and kiln car contact surface adopts soft high-alumina brick, and the design of hyperbolic envelope (male-female engagement contact) and friction sealed (plane contact) effectively prevents high-temperature gas to leak, the situation of heat losses.
