Split type efficient flue gas trapping device and method for discharging of ring cold machine

Abstract

The invention discloses a split type efficient flue gas trapping device for discharging of a ring cold machine. The split type efficient flue gas trapping device for discharging of the ring cold machine comprises a split type large discharging cover and T-shaped sealing grooves formed in the two sides of the lower end of the split type large discharging cover, wherein the split type large discharging large cover is connected onto a ring cold machine platform through the T-shaped sealing grooves, and is connected to the upper part of a ring cold machine trolley in a sleeving mode; multiple exhaust inlets are formed in the middle of the upper part of the split type large discharging cover; flow guide plates are arranged on the two sides of the inner bottom of the split type large discharging large cover and located below the exhaust inlets; and the exhaust inlets are connected with a dust removal pipeline and used for trapping smoke dust at the annular cooling discharging position of a sintering machine. According to the split type efficient flue gas trapping device and method for discharging of the ring cold machine provided by the invention, the structure of the split type large discharging cover is changed, and the T-shaped sealing grooves are arranged to prevent the smoke dust from escaping, so that the dust trapping efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of sintering fume collection, in particular to a split-type high-efficiency fume collection device and method for unloading an annular cooler. Background technique [0002] The sintering production process is that raw materials such as concentrate powder, limestone, lime and other fuels are mixed with crushed coke, anthracite and other fuels according to a certain ratio, and then the materials are placed in the sintering head. It is broken naturally by its own gravity, and then crushed by a single-roller crusher. After being screened in a chute, it enters a ring cooler to cool down. Finally, the cooled sinter is screened for whole grains and sent to the sintered product warehouse through a belt. The blast furnace ironmaking method is used. [0003] When the trolley of the ring cooler is turned downwards and unloaded, it will generate a large amount of intermittent smoke and dust, with a dust concentration o...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the overall seal between the large unloading hood and the platform of the annular cooler is not tight, and part of the smoke escapes from the gaps on both sides of the large unloading hood and the platform of the annular cooler, which greatly pollutes the working environment. , and proposed a split-type high-efficiency flue gas capture device and method for unloading the ring cooler
