Abstract

The utility model discloses a coal gangue brick tunnel furnace easy to evacuate smoke. The coal gangue brick tunnel furnace comprises a coal gangue tunnel furnace body. Twelve pairs of smoke-evacuating branch pipes are uniformly mounted and arranged from a tenth station of a roasting section of the furnace body to a first station of a preheating section. In the utility model, as the smoke evacuation flow path is reduced from the original 148 meters to 114 meters, the resistance is reduced, the smoke evacuation amount and the oxygen supply amount are increased, and the temperature increasing speed is enhanced from the original 41.2 DEG C/h to 75 DEG C/h, and therefore the designed yield requirement is satisfied.

Description

The colliery wastes brick tunnel cave that is easy to discharge fume
Technical field
The utility model relates to the colliery wastes brick tunnel cave.
Background technology
The typing kiln that existing colliery wastes brick tunnel cave is domestic design.Because be just to begin smoke evacuation in the 6th parking stall of preheating section in the former design, the smoke evacuation arm is only established seven pairs, so distinguished and admirable stroke reaches 148 meters; Resistance is big, and oxygen supply is not enough, makes kiln temperature low; Cause base, the base phenomenon of collapsing to occur falling, seriously restricted production, cause the furnace superintendent phase can not reach product.
Summary of the invention
For solving the prior art problem, the utility model improves present tunnel cave, and a kind of colliery wastes brick tunnel cave that is easy to discharge fume is provided, to reach the good purpose of smoke discharging effect.
The technical scheme that the utility model adopts is: it comprises gangue tunnel kiln body, it is characterized in that, begins 12 pairs of smoke evacuation arms to the even mounting arrangements in first parking stall of preheating section from the tenth parking stall of kiln body furnace zone.
The good effect of the utility model is: the smoke evacuation flow process shortens to 114 meters by original 148 meters, has reduced resistance, has increased exhaust smoke level and oxygen-supplying amount, makes temperature rise speed be promoted to 75 ℃/h by 41.2 ℃ original/h, reaches the requirement of design output.
Description of drawings
Fig. 1 is the sketch map of the utility model embodiment;
Fig. 2 is Figure 1A-A sectional drawing.
Marginal data: 1-kiln body; The 2-arm of discharging fume; 3-the tenth parking stall; 4-first parking stall.
The specific embodiment
As depicted in figs. 1 and 2; The colliery wastes brick tunnel cave of the utility model comprises existing gangue tunnel kiln body 1; As can be seen from the figure, the tenth parking stall 3 from kiln body 1 furnace zone begins to first parking stall, the 4 even mounting arrangements of preheating section 12 pairs of smoke evacuation arms 2 are arranged.
