Abstract
The utility model discloses an ultrafast energy conservation and emission reduction air duct system for a straight burning tunnel kiln, and relates to the air duct structure of the straight burning tunnel kiln. The ultrafast energy conservation and emission reduction air duct system for the straight burning tunnel kiln comprises a heating straight burning tunnel kiln (1), two ends of the heating straight burning tunnel kiln (1) are in a right-angled corner structure, and tunnel kiln inlet and outlet doors (2) are arranged on the end faces of two end corners of the heating straight burning tunnel kiln (1). Hot air inlet pipes (3) are arranged on the lower portion of one side of the heating straight burning tunnel kiln (1) at same intervals, the hot air inlet pipes (3) are round pipes, and air outlet holes are formed in the top portion of the heating straight burning tunnel kiln (1) at longitudinally same intervals. According to the ultrafast energy conservation and emission reduction air duct system for the straight burning tunnel kiln, the problems that the structure of a prior heating air duct for the heating straight burning tunnel kiln is unreasonable, and uneven in heating temperature are resolved.
Description
Technical field
The utility model relates to the air channel structure of straight fired tunnel kiln.
Background technology
Straight fired tunnel kiln generally is a long linear tunnel, and fixing wall and vault are arranged at its both sides and top, is moving kiln car on the track that lay the bottom.Combustion apparatus is located at the both sides, middle part of tunnel cave, consisted of fixing high temperature clinkering zone, the high-temperature flue gas that burning produces is under the effect of tunnel cave front end chimney or air-introduced machine, flow to the kiln hood direction along the tunnel, preheating enters the interior goods of kiln step by step simultaneously, and this section consisted of the preheating zone of tunnel cave.Kiln tail at tunnel cave blasts cold wind, and rear one section goods in the cooling tunnel kiln, the cold wind that blasts are flowed through goods and after being heated, being extracted out and send into drier as the thermal source of dried, and this section just consisted of the salband of tunnel cave.
Straight fired tunnel kiln has advantage energy-conservation, that reduce discharging, and still, there is the heating air duct unreasonable structure in the straight fired tunnel kiln of existing heating, the uneven permanent problem of heating-up temperature.
Summary of the invention
The utility model provides a kind of ultrafast energy-saving and emission-reduction straight fired tunnel kiln ducting system, and the utility model has solved the straight fired tunnel kiln of existing heating and had the heating air duct unreasonable structure, the uneven permanent problem of heating-up temperature.
For addressing the above problem, the utility model adopts following technical scheme: the straight fired tunnel kiln ducting system of ultrafast energy-saving and emission-reduction, comprise the straight fired tunnel kiln 1 of heating, at the rectangular corner structure in heating straight fired tunnel kiln 1 two ends, at the straight fired tunnel kiln 1 two ends corner end face of heating tunnel cave inlet/outlet 2 is arranged; Straight fired tunnel kiln 1 one side lower parts are equally spaced is provided with into warm-air pipe 3 in heating, and described to advance warm-air pipe 3 are pipes; At the vertical equally spaced venthole 4 that is arranged with in the straight fired tunnel kiln of heating 1 top.
Advantage of the present utility model: effective and reasonable utilization the energy, energy-conservation, reduce discharging, homogeneous heating, rational in infrastructure.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the top view of Fig. 1.
Symbol description among the figure: heat straight fired tunnel kiln 1, tunnel cave inlet/outlet 2, advance warm-air pipe 3, venthole 4.
The specific embodiment
The below is described in detail the utility model with best embodiment.
Shown in Fig. 1-2, the straight fired tunnel kiln ducting system of ultrafast energy-saving and emission-reduction comprises the straight fired tunnel kiln 1 of heating, at the rectangular corner structure in heating straight fired tunnel kiln 1 two ends, at the straight fired tunnel kiln 1 two ends corner end face of heating tunnel cave inlet/outlet 2 is arranged; Straight fired tunnel kiln 1 one side lower parts are equally spaced is provided with into warm-air pipe 3 in heating, and described to advance warm-air pipe 3 are pipes; At the vertical equally spaced venthole 4 that is arranged with in the straight fired tunnel kiln of heating 1 top.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the present utility model.
Claims (1)
