[0019] Please see attached Figure 1-2 An improved slag pit dust removal device comprises a shell 1, a supporting device, an upper sealing plate 2, a cooling device 4, a dust removal and demisting device, a slag pushing device 3 and a slag outlet 5. The upper sealing plate 2 is arranged on the top of the shell 1. The shell 1 is an arc-shaped body with a low middle and high sides. The supporting device is arranged at the bottom of the shell 1. The cooling device 4 is arranged in the shell 1. The slag pushing device 3 is arranged on one side of the shell 1. The slag outlet 5 is arranged on the other side of the shell 1 away from the slag pushing device 3. The dust removal and demisting device is arranged in the slag outlet 5. The cross section of the slag outlet 5 is in a right-angle trapezoidal shape, and the bottom of the slag outlet 5 is inclined.

[0020] The dust removal and demisting device comprises an air duct 6, which is arranged at the top of the slag outlet 5, and the number of the air ducts 6 is 2-3.

[0021] By adopting the above technical scheme, when working, the slag pushing device 3 will push the slag in the shell body 1 toward the slag outlet 5. When the slag amount or the slag temperature is high, the water temperature of the water seal tank of the slag discharger will increase, and may exceed 90°C in severe cases. At this time, the slag entering the slag bin will produce a large amount of water vapor, and the entire slag bin will be filled with fog. Therefore, by providing an air duct 6 at the inner top position of the slag outlet 5, the air duct 6 will form a negative pressure at the slag outlet 5 when it works, and then the dust and fog in the slag bin can be absorbed to avoid affecting the sight of the staff. Moreover, since the volume of the slag outlet 5 is small, the negative pressure formed by the air duct 6 is large, and the effect of absorbing dust and fog is better.

[0022] In some embodiments, the cooling device 4 includes an atomizing nozzle 7, which is disposed on an ascending slope section near the slag outlet 5 in the shell 1, and the spacing between the atomizing nozzles 7 is 30-40 cm.

[0023] By adopting the above technical scheme, high-pressure water is set so that the high-pressure water is sprayed out through the atomizing nozzle 7. After the high-pressure water is atomized by the atomizing nozzle 7, the small water droplets of 150 microns are combined with the dust in the air and the tiny 3-100 micron water droplets in the mist to form larger water droplets that fall to the ground, thereby achieving the effect of reducing fog and suppressing dust, and avoiding the situation where heavy fog fills the slag bin. By setting the spacing between the atomizing nozzles 7 to 30-40cm, the sprayed water mist forms a water curtain, thereby improving the atomization effect.

[0024] In some embodiments, the supporting device includes supporting rods 8 , and a plurality of supporting rods 8 are arranged at the bottom of the housing 1 .

[0025] With the above technical solution, the support rod 8 is used to support the housing 1 .
