Technical Field

[0001] The utility model relates to the technical field of converter evaporative cooling systems, in particular to a converter evaporative cooling spray gun system. Background Art

[0002] The evaporative cooler used in existing steel mills cools down the flue gas by mixing water and nitrogen and then atomizing it through a nozzle. The cooling water and coarse particles are combined to achieve the dust removal effect. However, in the existing cooling system, there is generally only a single cooling water ring pipe to mix nitrogen and cooling water. This mixing method consumes a lot of nitrogen, and the nitrogen consumption per ton of steel is 12m³ / t, and the atomization range is small.

[0003] Therefore, we improved the cold spray gun system to solve the problems of large nitrogen consumption and small atomization cooling range in the previous cooling system. Utility Model Content

[0009] The water loop pipe supplies liquid phase fluid to several groups of water branch pipes, and the gas loop pipe supplies gas phase fluid to several groups of gas branch pipes. The gas phase fluid enters the nozzle through the connecting pipe and mixes with the liquid phase fluid, and is ejected from the nozzle.

[0010] Preferably, the water circuit ring pipe and the gas circuit ring pipe are concentrically arranged from outside to inside.

[0011] Preferably, each group of water branch pipes has a group of gas branch pipes.

[0012] Preferably, the water branch pipes and gas branch pipes are arranged in 12 groups at equal intervals.

[0013] Preferably, the valve body I and the valve body II are manual ball valves.

[0014] Preferably, the flowmeter I is an electromagnetic flowmeter, and its flange is connected to the water branch pipe.

[0015] Preferably, the flow meter II is a vortex flow meter, and its flange is connected to the gas branch pipe.

[0016] Preferably, the filter I is a Y-type filter with a filtration mesh of 30 meshes.

[0017] Preferably, the filter II is a Y-type filter with a filtration mesh of 50 meshes.

[0018] Compared with the prior art, the beneficial technical effects of the utility model are:

[0019] (1) The water loop pipe and gas loop pipe of the cold spray gun system are connected to a plurality of water branch pipes and gas branch pipes. The water loop pipe supplies liquid phase fluid for cooling to the water branch pipe, and the gas loop pipe supplies gas phase fluid for cooling to the gas branch pipe. The gas phase fluid is sprayed out from the spray pipe after mixing with the liquid phase fluid, so as to cool the converter.

In addition, each group of water branch pipes and gas branch pipes can be independently controlled by a self-contained valve body and measured by a flow meter, which is very beneficial to the economical use of cooling liquid phase / gas phase and has strong controllability.

[0020] (2) There are 12 groups of water branch pipes and gas branch pipes that are equidistant and arranged in a ring on the water ring pipe and the gas ring pipe, which has a larger cooling coverage area and a better cooling effect;

[0021] (3) Each set of water branch pipes and gas branch pipes is equipped with a Y-type filter, which can filter the fluid in the water branch pipes and gas branch pipes. On the one hand, it can prevent the nozzle from being blocked after long-term use.

[0028] It should be noted that the water loop pipe 1 and the gas loop pipe 2 of the cold spray gun system are connected to a plurality of groups of water branch pipes 3 and gas branch pipes 4. The water loop pipe 1 supplies liquid phase fluid for cooling to the water branch pipe 3, and the gas loop pipe 2 supplies gas phase fluid for cooling to the gas branch pipe 4. The gas phase fluid is sprayed out from the nozzle 301 after mixing with the liquid phase fluid, so as to cool the converter.

[0030] Furthermore, the water branch pipes 3 and the gas branch pipes 4 are arranged in 12 groups at equal distances. The 12 groups of water branch pipes 3 can better cool the converter, with high cooling efficiency and wide cooling coverage.
