Problems solved by technology

It can be seen from the above analysis that, firstly, the backfired coal-water slurry liquid slagging combustion furnace is not suitable for the combustion of emulsified coke slurry; secondly, the combustion chamber temperature of the backfired coal water slurry liquid slagging combustion furnace is still low The ash melting point of the emulsified coke slurry ash cannot be reached, and the emulsified coke slurry ash cannot be liquefied; finally, the combustion chamber structure of the reverse combustion type coal-water slurry liquid slagging combustion furnace is complicated, and the manufacturing cost is high
[0007] Finally, in order to make the system operate continuously and normally, the slag receiving device at the lower part of the burner must be replaced in time, and the liquid slag also contains a large amount of waste heat that can be used. If the liquid slag is directly flowed into the slag receiving device, it will cause waste of energy

Embodiment 1

[0052] Please refer to figure 1 and figure 2 , The metallurgical reverberatory kiln of the present invention includes a vertical reverberatory kiln body and an emulsified coke slurry cyclone combustion device. Wherein, the reflection kiln body includes a kiln chamber 402, three flame inlets 403 opened on the front side wall of the kiln room 402, a flue gas outlet 404 opened on the rear side wall of the kiln room 402, and two Oil burner 405 on the side wall. The emulsified coke slurry cyclone combustion device includes a shell 10 , an emulsified coke slurry burner 70 , an oil burner (not shown in the figure), a gas burner (not shown in the figure), and a slagging device 500 . The emulsified coke slurry cyclone combustion device communicates with the flame inlet 403 of the kiln chamber 402 through the hot air pipe 104 .

[0053] Wherein, three flame inlets 403 are equally spaced and parallel distributed on the front side wall of the kiln chamber 402 . The entrances of the t...

Embodiment 2

[0075] Please refer to Figure 5 and Figure 6 , this embodiment is similar to Embodiment 1, the difference is:

[0076] Two flame inlets 403 are distributed on the front side wall of the kiln chamber 402 in parallel.

[0077] Both the flame inlet 403 and the inlet of the oil burner 405 at the kiln chamber 402 are inclined about 50 degrees to the bottom wall of the kiln chamber 402 .

[0078] The opening area of ​​the liquid slag outlet 66 on the inner wall of the side wall 60 is approximately equal to one-twentieth of the cross-sectional area of ​​the combustion space 30 .

[0079] The vertical distance between the inner wall of the front end wall 20 and the inner wall of the rear end wall 40 is 1.5 times the inner diameter of the combustion space 30 .

[0080] The diameter of the outlet 44 is about half of the inner diameter of the combustion space 30 , and a conical transition chamber 48 is formed between the outlet 44 and the side wall 60 of the housing 10 . That is, a...

Embodiment 3

[0089] This embodiment is similar to Embodiment 1, the difference is:

[0090] An oil burner 405 may be arranged on the front side wall of the kiln chamber 402 .

[0091] Both the flame inlet 403 and the inlet of the oil burner 405 in the kiln chamber 402 are inclined about 40 degrees to the bottom wall of the kiln chamber 402 .

[0092] The metallurgical reverberatory kiln using the emulsified coke slurry cyclone combustion device is provided with two liquid slag outlets 66 of the same size distributed at intervals, and the opening area of ​​each liquid slag outlet 66 on the inner wall of the side wall 60 is approximately equal to the cross-sectional area of ​​the combustion space one-thirtieth of.

[0093] The two liquid slag outlets 66 are surrounded by the same transition cavity 666 and are connected to the slag holding space of the same slag discharge vehicle 500 .

[0094] The vertical distance between the inner wall of the rear end wall 40 and the inner wall of the fr...

Abstract

The invention discloses a metallurgical reverberatory kiln adopting an emulsified coke slurry cyclone burning device, which comprises a reverberatory kiln body and an emulsified coke slurry cyclone burning device. It includes a shell surrounded by a front end wall, a rear end wall, and a side wall. A cylindrical combustion space is formed inside the shell, and at least one emulsified coke burner and at least one oil burner are arranged on the front end wall And / or at least one gas burner, an outlet is opened on the rear end wall, the outlet communicates with the flame inlet of the kiln chamber through the hot air pipe, and two or more sets of tangential air inlets are arranged at intervals on the side wall of the shell, located at At least one liquid slag outlet is opened on the side wall at the bottom of the combustion space at a position adjacent to the rear end wall. The metallurgical reverberatory kiln of the present invention adopts the emulsified coke slurry cyclone combustion device and uses the emulsified coke slurry as fuel, which saves fuel cost and realizes optimal utilization of resources.

Description

technical field [0001] The invention relates to a metallurgical reverberatory kiln, in particular to a metallurgical reverberatory kiln using an emulsified coke slurry burning device. Background technique [0002] Generally, the relatively clean energy used in metallurgical reverberatory kilns is mainly oil, natural gas or coal gas, etc. However, this has greatly increased the fuel cost of metallurgical reverberatory kilns, seriously affecting the survival of enterprises that use and manufacture metallurgical reverberatory kilns. [0003] For this reason, those skilled in the art are working hard to develop new available energy sources. Inexpensive, efficient and clean emulsified coke slurry fuel has gradually become a new favorite in this field. The use of emulsified coke slurry fuel in metallurgical reverberatory kilns can not only make reasonable use of natural resources, but also reduce the fuel cost of metallurgical reverberatory kilns. Therefore, countries all over th...
