Description
Technical Field
The utility model belongs to the technical field of relevant equipment for uneven high-temperature flue gas spraying cooling and dust removal in converter steelmaking, and particularly relates to a device for cooling uneven high-temperature flue gas in a flue at the tail end of a converter.
Background
The flue gas temperature at the tail end flue of the converter is up to 700-.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a device for cooling high-temperature flue gas at the tail end of a converter, which has the advantage of uniform flue gas temperature and solves the problems of non-uniform temperature drop and ash adhesion.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a give inhomogeneous high temperature flue gas cooling's of converter terminal flue device, includes spray gun, valve, terminal flue and the cold cylinder body of evaporation, and terminal flue passes through non-metallic compensator with the cold cylinder body of evaporation and is connected, installs a plurality of spray guns in the middle of it, the internal surface of spray gun all is provided with the valve.
Preferably, the spray guns are annularly distributed on the periphery of the tail end flue.
Preferably, the lances all have different lengths.
Compared with the prior art, the utility model has the following beneficial effects:
1. according to the utility model, the spray guns are unevenly distributed for cooling and dedusting the flue gas in an uneven temperature field, so that accurate cooling of the uneven temperature field is realized, the dedusting effect is increased, the water consumption is reduced under the same cooling effect, and favorable conditions are created for cooling and secondary dedusting of subsequent processes.
2. The arrangement form of the spray gun can reduce the local pressure loss of the primary dust removal at the position, and is favorable for improving the environmental pollution caused by the overflow of the flue gas at the furnace mouth during the smelting of the converter.
3. The uneven arrangement form of the spray guns can avoid the ash sticking on the inner wall of the evaporative cooling cylinder body, so that the process equipment at the position is maintenance-free, the manual cleaning is reduced, the production time is saved, and the labor intensity and the safety risk are reduced.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
In the figure: 1. a spray gun; 2. a valve; 3. a tail end flue; 4. evaporating the cold cylinder.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "connected", and the like are to be construed broadly, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The components of the spray gun 1, the valve 2, the end flue 3 and the evaporative cooling cylinder 4 of the present invention are all common standard components or components known to those skilled in the art, and the structure and principle thereof can be known to those skilled in the art through technical manuals or through routine experimentation.
Referring to fig. 1, a device for cooling uneven high-temperature flue gas in a converter tail end flue comprises a spray gun 1, a valve 2, a tail end flue 3 and an evaporation cooling cylinder 4, wherein the tail end flue 3 is connected with the evaporation cooling cylinder 4 through a non-metal compensator, a plurality of spray guns 1 are arranged in the middle of the device, valves 2 are arranged on the inner surfaces of the spray guns 1, the spray guns 1 are annularly distributed on the periphery of a tail end flue 3 to deal with the phenomenon of uneven temperature of high-temperature flue gas caused by airflow, the arrangement is that uneven installation positions are reserved in advance when the tail end flue 3 is manufactured, the uneven arrangement cannot be changed once the tail end flue 3 is manufactured, the lengths of the spray guns 1 are different, according to the in-service use, the opening degree of the valve 2 on the water inlet pipe of each spray gun 1 is controlled, so that the opening degree of the valve 2 corresponding to the high-temperature area is larger, and more water is sprayed, thereby achieving the purpose of uniform cooling.
During the use, the flue gas that is used for inhomogeneous temperature field through a plurality of spray gun 1 inhomogeneous arrangement is cooled down and is removed dust, realized the accurate cooling to inhomogeneous temperature field, increase dust removal effect, and the water consumption has been reduced under equal cooling effect, the advantage has been created for the cooling and the second grade of follow-up procedure, spray gun 1's the form of arranging can reduce the local pressure loss of this place one-level dust removal, the environmental pollution that the excessive and cause of furnace mouth flue gas when favourable improvement converter is smelted, spray gun 1 inhomogeneous arrangement form can avoid evaporating 4 inner walls of cold cylinder and glue the ash, make the process equipment at this position reach non-maintaining, manual cleaning has been reduced, not only saved production time but also reduced intensity of labour and safe risk.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
