Abstract

The invention discloses a preheater device for a blast furnace hot blast stove. The preheater device comprises a preheating barrel, wherein the inner cavity wall of the preheating barrel is fixedly connected with a cross-shaped support, the left side wall of the cross-shaped support is provided with a draft fan, the inner cavity wall of the preheating barrel is fixedly connected with a filter plate, the left side wall of the filter plate is provided with a sweeping mechanism, the left end surface of the preheating barrel communicates with an air inlet pipe, a dust suction mechanism is arranged on the upper end surface of the preheating barrel, the right side wall of the dust suction mechanism is fixedly connected with a collecting box, the lower end surface of the dust suction mechanism communicates with a dust suction pipe, the front end surface of the collecting box is slidably connected with a collecting drawer, and a dust outlet pipe of the dust suction mechanism communicates with the collecting box. The invention relates to the technical field of preheaters for hot blast stoves. The preheater device for the blast furnace hot blast stove solves the problem that it is inconvenient for an existing preheater for a hot blast stove to filter dust and slag in tail gas of the hot blast stove, filtered dust is inconvenient to clean, and the preheating effect is poor.

Description

technical field [0001] The invention relates to the technical field of hot blast stove preheaters, in particular to a blast furnace hot blast stove preheater device. Background technique [0002] The hot blast stove is one of the main supporting equipment for the blast furnace in the ironworks. Its function is to heat the blast to the required temperature to improve the benefit and efficiency of the blast furnace. The hot blast stove preheater is a heating surface that uses the flue gas in the boiler tail flue to preheat the air before entering the boiler to a certain temperature through the internal cooling fins. It is used to improve the heat exchange performance of the boiler and reduce energy consumption. [0003] The publication number is: CN201920717229.5 discloses an air preheater for a blast furnace. The blast furnace air preheater includes a flue gas device and an air device. The right side of the flue gas device is provided with an air device. The flue gas device...
