It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, the present utility model provides a combined gas cooler comprising: a horizontal gas cooler body 10 provided on the horizontal gas pipe 30; at least one atomizing spray gun 20 is arranged on the horizontal gas cooler body 10 in a penetrating way.

The combined gas cooler has less water consumption and electricity consumption, and the spraying mode can lead the moisture content in the converter flue gas to be smaller, thereby reducing the corrosion of the converter flue gas to the pipeline and simultaneously reducing the load of the pipeline.

Specifically, as shown in fig. 1 and 2, the horizontal gas cooler body 10 is connected to the horizontal gas pipe 30 for cooling the gas in the horizontal gas pipe 30. The horizontal gas cooler body 10 is different from a vertical gas cooler which is conventionally arranged, the extending direction of the horizontal gas cooler body 10 is the same as that of the horizontal gas pipeline 30, and the horizontal gas cooler body is equivalent to replacing one section of the conventional horizontal gas pipeline 30 with the horizontal gas cooler body 10, so that the installation space of the gas cooler is not required to be independently arranged, and the occupied space of the whole converter gas treatment equipment is saved.

According to one embodiment of the present utility model, as shown in fig. 1 and 2, the horizontal gas cooler body 10 has a shuttle-shaped structure, that is, the diameter of both ends of the horizontal gas cooler body 10 is smaller than the diameter of the middle portion thereof.

Further, at least one atomizing spray gun 20 is arranged on the side wall of the horizontal gas cooler body 10 in a penetrating manner, a liquid pipeline is connected to the part, located outside the horizontal gas cooler body 10, of the atomizing spray gun 20, a spray head is arranged on the part, located inside the horizontal gas cooler body 10, of the atomizing spray gun 20, and the spray head of the atomizing spray gun 20 can spray atomized liquid so as to cool flue gas of the horizontal gas cooler body 10.

According to an embodiment of the present utility model, as shown in fig. 2, a plurality of atomizing spray guns 20 are provided to the horizontal gas cooler body 10 in a penetrating manner, and the plurality of atomizing spray guns 20 are uniformly arranged in the circumferential direction of the horizontal gas cooler body 10. The number of the atomizing spray guns 20 may be determined according to actual needs, and is not particularly limited herein, as long as the cooling effect of the horizontal gas cooler body 10 can be ensured.

According to one embodiment of the present utility model, as shown in FIG. 2, the outlet direction of the spray head of atomizing spray gun 20 is opposite to the direction of gas flow within horizontal gas conduit 30. The outlet direction of the atomized liquid of the atomizing spray gun 20 is set towards the flow direction of the flue gas, so that the cooling effect of the atomizing spray gun 20 is ensured.

According to one embodiment of the present utility model, the atomizing spray gun 20 is a dual medium atomizing spray gun having an air outlet and a liquid outlet disposed adjacently, and atomized water droplets sprayed from the dual medium atomizing spray gun are within 80 microns.

The evaporation time of atomized water drops sprayed by the double-medium atomizing spray gun is about 1s, and meanwhile, the atomized water drops reversely contact with the flue gas, and the flow rate of the flue gas can reach 10m/s-15m/s. However, in order to avoid that the length of the horizontal gas cooler body 10 is not too long, the flow rate of the flue gas can be set to be about 5m/s, and the length of the horizontal gas cooler body 10 can meet the requirement at about 7 m. Different converters correspond to different flue gas amounts, and different flue gas amounts correspond to different cooling water spraying amounts. The subsequent design can be calculated according to the actual requirement, and the horizontal gas cooler body 10 with the proper size is selected.

According to one embodiment of the present utility model, as shown in fig. 1, the bottom of the horizontal gas cooler body 10 is provided with a drain port 11. The water outlet 11 is used for discharging accumulated liquid of the horizontal gas cooler body 10, so that excessive load of equipment caused by the liquid in the water outlet is avoided, and meanwhile, corrosion of the liquid to the horizontal gas cooler body 10 is avoided.

Further, as shown in fig. 1, the bottom wall of the horizontal gas cooler body 10 is inclined toward the drain port 11. The inclined bottom wall can ensure that the liquid in the horizontal gas cooler body 10 can be smoothly discharged from the water outlet 11.

In a preferred embodiment of the present utility model, a drain pipe 12 is connected to the drain port 11, and a water seal tank 13 is connected to the drain pipe 12. The water seal box 13 is used for storing the liquid discharged from the horizontal gas cooler body 10.

Preferably, a water stop valve 14 is arranged on the water drain pipe 12, and the water stop valve 14 can control the opening and closing of the water drain pipe 12, so that liquid in the horizontal gas cooler body 10 is discharged into the water seal box 13 through the water drain pipe 12.

According to one embodiment of the present utility model, as shown in fig. 1 and 2, both ends of the horizontal gas cooler body 10 are provided with supporting frames 15, and the supporting frames 15 are used to support the horizontal gas cooler body 10 so as to be firmly fixed on the horizontal gas pipe 30.

The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the utility model, and is not meant to limit the scope of the utility model, but to limit the utility model to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the utility model are intended to be included within the scope of the utility model.
