Description
Technical Field
The invention relates to the technical field of dry quenching, in particular to a sealed coke tank for dry quenching.
Background
The coke dry quenching is an important technology for energy conservation and emission reduction in the metallurgical industry, and the principle is to cool red coke by heat exchange between inert gas and the red coke in a coke dry quenching furnace. The coke tank is a red coke carrying device. During coke pushing, the coke pusher pushes the red coke in the coking chamber into the coke tank through the coke guide grid, then the red coke is conveyed to the bottom of a dry quenching lifting derrick by a carrying vehicle, and finally the red coke is lifted to the top of a dry quenching furnace by a lifter to be loaded with coke.
In the existing dry quenching production process, in the process that a coke tank receives red coke in front of a furnace and is conveyed to the bottom of a lifting derrick, the coke tank is always exposed in the atmosphere, so that the red coke is directly combusted in the air, a large amount of carbon dioxide is discharged, and harmful gases and dust are volatilized; and when the environment is polluted, part of heat is lost, and the heat utilization rate is reduced.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the sealed coke tank for dry quenching, which reduces the area of red coke exposed in the atmosphere in the coke conveying process of the coke tank, thereby reducing the burning loss of the red coke and the emission of harmful gas.
In order to achieve the purpose, the invention adopts the following technical scheme:
a sealed coke tank for dry quenching comprises a coke tank body, a lifting device and a coke tank cover; the coke tank cover is fixedly connected to the lifting device, the coke tank cover is positioned right above the coke tank body, the bottom of the coke tank cover is higher than the top of the coke tank body, and the coke tank cover is static when the coke tank body rotates; the coke tank cover is provided with a blanking port at the blanking position of the coke guide grid, the size of the blanking port is matched with the area of the blanking area of the coke guide grid, and the coke tank cover covers the opening of the coke tank except the blanking port.
The bottom of the coke tank cover is spaced from the top of the coke tank body; the spacing is more than 0mm and less than or equal to 200 mm.
And a heat insulation layer is arranged at the bottom of the coke tank cover.
The edge of coke pot cover is equipped with a plurality of supports, and hoisting device is equipped with corresponding supporting seat, and the support is fixed on the supporting seat in order to dismantle to place.
The support is fixed on the support seat through a bolt.
Compared with the prior art, the invention has the beneficial effects that:
the device comprises a coke tank body, a lifting device and a coke tank cover, wherein the coke tank body and the lifting device are traditional equipment, and the coke tank cover is provided with a blanking port at the blanking position of a coke guide grid, so that red coke pushed out of a carbonization chamber can smoothly fall into the coke tank through the blanking port; the coke jar cover is fixed on the lifting device, and the coke jar cover support keeps certain clearance with rotatory coke jar body in circumference and height, and when the coke jar body was rotatory, the coke jar cover kept static, did not influence the rotation of coke jar body.
1) The sealed coke tank provided by the invention can effectively reduce the contact with air in the red coke transportation process, and compared with the traditional coke tank, the sealed coke tank reduces the emission of harmful gas and dust in the red coke transportation process, and is more energy-saving and environment-friendly.
2) The invention reduces the burning loss in the red coke transportation process and improves the heat energy utilization rate.
3) The invention can be modified on the existing coke tank, and has the advantages of easy implementation, low investment and good economical efficiency.
