Abstract

The utility model discloses a novel inner ring wall of a dry quenching furnace. Holes are formed in the inner ring wall. According to the novel inner ring wall disclosed by the utility model, the holes are formed in a brick body of the inner ring wall, so that an air passing area at the outlet of the dry quenching furnace is increased, the coke stress at a chute is significantly relieved, and solutions for improving the circulating air volume are provided, thus the production capacity of a dry quenching furnace device can be improved, and the recycling of red coke sensible heat is improved. Moreover, according to the novel inner ring wall disclosed by the utility model, under the condition that the production capacity is subsequently ensured through the areas of the holes in the inner ring wall, the width of a bracket can be increased, and then, the strength of the bracket can be enhanced, so that the service life of the bracket can be prolonged. Finally, the novel inner ring wall disclosed by the utility model relieves the stress at the bottom of the inner ring wall and avoids 'bulging' collapse of the inner ring wall so as to ensure that the dry quenching furnace is more economical and can be operated more efficiently.

Description

Ringwall in a kind of Novel dry quenching furnace

Technical field

The utility model relates to the dry stove technical field of putting out, and is specifically related to ringwall in a kind of Novel dry quenching furnace.

Background technology

In existing dry design of putting out stove, because being supported the dry stove chamber superstructure requirement that prestores of putting out, so can not be by reducing chute place bracket width, increase chute and cross wind area, thereby air quantity is when excessive, just there is the problem of floating in chute place coke, is directly restricting dry coke quenching throughput.The dry interior ringwall of stove annular passage that puts out all adopts integral seamless to build by laying bricks or stones simultaneously, and the dry recycle gas putting out in stove all flows out by chute, enters boiler.In this traditional design, it is limited that chute is crossed wind area, and the windage that chute place coke is subject to is large, and coke easily floats.

Utility model content

Technical problem to be solved in the utility model is all to flow out by chute for the dry recycle gas putting out in stove of the prior art, cause chute region coke to be subject to blowing compared with air flow, easily cause the problem that coke floats and provide a kind of and can effectively solve ringwall in the Novel dry quenching furnace that coke floats problem.

Adopt following technical scheme for solving technical problem of the present utility model:

Ringwall in a kind of Novel dry quenching furnace, described interior ringwall is provided with hole.

Described hole starts arranged evenly above from 1 meter of interior ringwall bottom, perforate distributed areas height is 2-3 meters.

Side rake angle is inwardly put out in stove outside ringwall upwards along dry in described hole.

Described hole is square opening or circular port.

The utility model, by perforate on the brick body of interior ringwall, has increased the dry wind area excessively that puts out outlet of still place, has significant effect to alleviating chute place coke stressing conditions.Provide solution for improving air circulation, and then can improve the dry furnace apparatus throughput of putting out, improved the aobvious pick up the heat of red Jiao.In addition by the utility model for follow-up by interior ringwall perforated area, guarantee in the situation of throughput, can increase bracket width and then strengthen bracket intensity, extend the bracket life-span.Finally, the utility model, stressed for ringwall bottom in alleviating, avoid interior ringwall " bulge " to cave in.Thereby play and make dryly to put out that stove is more economical, the effect of efficient operation.

Fig. 3 is the utility model square opening schematic diagram.

Fig. 4 is the utility model circular port schematic diagram.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

A ringwall in Novel dry quenching furnace as shown in Figure 1, the height of interior ringwall opening area is 2-3 meters, on interior ringwall, has hole, and hole 1 is square opening or circular port as shown in Figure 3, Figure 4, and hole 1 starts arranged evenly from 1 meter of interior ringwall 2 bottom above.The outer side rake angle of ringwall 2 is inwardly put out in stove upwards along dry in hole 1 as shown in Figure 2.

Perforate 1 on interior ringwall 2, in the regional production of perforate 1, playing can be by the effect of recycle gas, has therefore realized and has increased the dry wind area excessively that puts out outlet of still, and air quantity is crossed to by chute place shunting action, for increasing air circulation, avoids coke to float useful.Because of perforate 1 on interior ringwall 2, alleviate the weight of interior ringwall 2 bodies of wall, thereby can reduce the stressed load of bracket simultaneously, extended the bracket life-span useful.

As shown in Figure 1, hole 1 on interior ringwall 2 starts arranged evenly from 1 meter of interior ringwall 1 bottom above, the height in the region of perforate 1 is 2-3 meters, and this structure is useful for the ringwall 2 stressed outside expansions in bottom in alleviating, and then can avoid the at present dry problem that stove occurs that interior ringwall 1 " bulge " caves in of putting out.To put out in stove the inwardly outer side rake angle of ringwall 2 be upwards situation about blowing out from perforate 1 in order to reduce coke along dry in perforate 1; The coke that part is blown falls into chute, is declined and is continued to get back to cooling room by coke discharging material level.

Above-described is only general embodiment of the present utility model, does not limit to originally practical.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, all can realize the purpose of this utility model, all should be considered as protection domain of the present utility model.
