Embodiment 1

[0047] This embodiment discloses an adaptive water mist dust removal system for a casting workshop, including a water mist curtain generation module and an exhaust module, and the water mist curtain generation module is used to generate a water mist curtain to block the smoke and dust emitted by the casting workshop And reduce the temperature of the smoke and dust, the exhaust module is used to take away the smoke and dust isolated by the water mist curtain generating module;

[0048] The exhaust module includes an exhaust hood 1, an exhaust pipe 2, a tuyere 3 and a fan 4, the exhaust hood 1 is arranged in the casting workshop, the exhaust pipe 2 includes a front section and a rear section, and the exhaust The front section of the pipe 2 is arranged in the exhaust hood 1 and is divided into n pipe sections according to the number n of casting molds contained in the casting workshop. Each pipe section is provided with a plurality of tuyere 3 and the total area of ​​the tuyere of...

Embodiment 2

[0073] This embodiment discloses an adaptive water mist dust removal system for a casting workshop. On the basis of Embodiment 1, the following technical features are also disclosed:

[0074] In the present embodiment, there are four casting molds emitting high-temperature smoke and dust below the exhaust hood 1 and the side length of the mold is 2 meters. The longer the distance of the air duct, the greater the resistance along the way. With the increase of the distance of the air duct, the air volume will be greatly reduced, resulting in uneven distribution of air volume in the front and rear sections of the exhaust duct. Therefore, there is often a case where the exhaust hood 1 is effective in controlling the high-temperature smoke and dust emitted by the first casting mold, but the effect becomes worse as it goes further. In view of this problem, in this embodiment, the exhaust pipe 2 is divided into four sections, and slit-type air outlets at different intervals are provi...

Abstract

The invention belongs to the field of environment-friendly machinery and discloses a self-adaptive water mist dust removal system for a casting workshop. The water mist dust removal system comprisesa water mist curtain generation module and an exhaust module, wherein the water mist curtain generation module is used for generating a water mist curtain to block smoke dust emitted by the casting workshop and reduce the temperature of the smoke dust, and the exhaust module is used for pumping away the smoke dust isolated by the water mist curtain generation module. The formed water mist curtaineffectively blocks a smoke dust area and external air, smoke dust can be effectively prevented from escaping to the outside from the side face of the casting bed, technological operation is not affected, formed water mist and emitted smoke dust act, and the trapping efficiency of a receiving hood can be improved. Due to the fact that the sizes of all parts and the water amount and air amount are designed in advance, the method is suitable for various casting conditions.

Description

technical field [0001] The invention belongs to the field of environmental protection machinery, and in particular relates to an adaptive water mist dust removal system used in a casting workshop. Background technique [0002] The existing flue gas collection system in the factory has good efficiency in collecting most of the point sources of smoke and dust around the submerged arc furnace. However, when the refined ferromanganese is poured into the casting mold, there is still smoke and dust escaping, and due to the large surface area of ​​exposed metal, The sides of the casting bed need to be open to allow the entry of loaders to scoop away the solidified alloy ingots. The soot is therefore easily disturbed by the lateral air flow, so that the soot contaminates the outer area. These fumes contain fine manganese oxides, especially Mn 3 o 4 , because of its small particle size, it is easily carried away by the air. People who have been engaged in metal smelting for a lon...
