[0040] The present application will be described below with reference to the drawings:

[0041] Figure 1 The structure of a kind of emission reduction system in some embodiments of the present application or certain embodiments is shown, reference Figure 1 The present application provides an emission reduction system, comprising:

[0042] The ladle 1 is used to receive steel slag or molten steel.

[0043] The support 2 is spaced apart from and higher than the ladle 1.

[0044] The dust collecting cover 3 covers the ladle 1 and is located on both sides of the ladle 1. One side of the dust collecting cover 3 is supported on the support 2, and the side of the dust collecting cover 3 supported on the support 2 is higher than the other side of the dust collecting cover 3. The dust collecting cover 3 is provided with a spaced pouring opening 31 and a smoke exhaust opening 32. The pouring opening 31 is used to be opposite to the ladle 1.

[0045] The dust collecting mechanism 4 is provided with a dust suction opening 41 communicated with the smoke exhaust opening 32.

[0046] The ladle 1 in the emission reduction system can receive steel slag or molten steel, and smoke dust will be generated in the process of receiving the steel slag or molten steel. The support 2 is spaced from and higher than the ladle 1, and one side of the dust collecting cover 3 is supported on the support 2, so that the one side of the dust collecting cover 3 can be higher than the ladle 1. The dust collecting cover 3 is located on both sides of the ladle 1 and covers the ladle 1, which can collect smoke gas in the ladle 1. At the same time, the pouring opening 31 on the other side of the dust collecting cover 3 opposite to the ladle 1 provides space for pouring molten steel or steel slag into the ladle 1. The other side of the dust collecting cover 3 can be supported on the ground. While collecting smoke gas, the addition of the support 2 makes the dust collecting cover 3 not need to be prepared in the form of completely covering the ladle 1, which correspondingly reduces the weight of the dust collecting cover 3. The dust collecting cover 3 and the support 2 are not an integral structure, which can facilitate the separation of the dust collecting cover 3 and the support 2 for cleaning and maintenance. In addition, the heights of the two sides of the dust collecting cover 3 are different. If the dust collecting cover 3 needs to be cleaned, it can be moved from the higher side of the support 2 on which the dust collecting cover 3 is supported, which facilitates the movement and subsequent cleaning and maintenance of the dust collecting cover 3, and is beneficial to shorten the maintenance time to reduce the influence on the production efficiency of steel smelting. The smoke dust collected in the dust collecting cover 3 can enter the smoke exhaust opening 32 of the dust collecting cover 3, then enter the dust suction opening 41 of the dust collecting mechanism 4 from the smoke exhaust opening 32, and complete the collection of smoke dust to play a role in emission reduction. While completing the collection of smoke dust, the time required for cleaning and maintenance of the dust collecting cover 3 can be shortened, the dust collecting cover 3 can be frequently used to ensure the production efficiency of steel smelting, and to a certain extent, the technical problem that the production efficiency of steel smelting is affected is solved.

[0047] The emission reduction system has the above structure, and the structure of the emission reduction system is also relatively simple and light, which can reduce the overall space required, and is also beneficial to reduce the working and maintenance cost of the emission reduction system.

[0048] It should be noted that one side of the dust cover 3 is supported on the support 2, and the other side of the dust cover 3 can be supported on the ground or the equipment adjacent to the working position of the ladle 1, and can be adjusted according to the position of the ladle 1. The smoke dust enters the dust suction mechanism 4 and is not directly exhausted, so that the emission reduction effect can be achieved. In the present application, the support 2 is higher than the ladle 1, and the support 2 is higher than the ladle 1 when the support 2 and the ladle 1 are in use and the support 2 and the ladle 1 are in the same environment. The height difference between the two sides of the dust cover 3, and the liquid level dust cover 3 is in use, the height relationship between the two sides of the dust cover 3.

[0049] In some or certain embodiments, the emission reduction system can also include a guide rail 5 arranged on the ground, and the guide rail 5 and the support 2 are arranged on both sides of the ladle 1, respectively, and the other side of the dust cover 3 can also be supported or clamped on the guide rail 5. The position of the dust cover 3 is relatively stable, and the dust cover 3 can also move relative to the guide rail 5 for cleaning.
