Problems solved by technology

[0002] Dust-containing exhaust coolers such as submerged arc furnaces or submerged arc furnaces have always adopted the cooling method of top-in and bottom-out air tubes. After the dust in the exhaust gas on the upper part of the cooler decelerates, it is easy to settle on the top of the tubes, blocking the cooling tubes and increasing the ventilation resistance. The smelting smoke exhaust is not smooth, which affects the smelting operation environment. At the same time, the power of the environmental protection fan of the submerged arc furnace is increased, which increases the power consumption; and there is no space and position for the upper air inlet to set the dust settlement tank.

Embodiment Construction

[0011] 1) Dust-containing tail gas coolers such as submerged arc furnaces or submerged electric furnaces use bottom-inlet and top-outlet coolers, and the number, diameter, cross-section and length of the cooling tubes (5) and the spacing between the tubes are designed according to the temperature and air volume of the smelting tail gas .

[0012] 2) Bottom air inlet chamber (4) is installed at the bottom of the bottom of the bottom air inlet chamber (4), and dust sedimentation chamber (10) and ash discharge valve (1) are arranged at the bottom of the bottom air inlet chamber (4). The specific size and shape are according to the design requirements , Dust volume and air cooling requirements are determined.

[0013] 3) The top of the cooler with bottom inlet and top outlet is provided with a top outlet bin (6), and the outlet bin is connected to the main outlet pipe (8).

[0014] 4) Choose natural cooling or fan frequency conversion air cooling according to air cooling requirem...

Abstract

The invention relates to a bottom-in and top-out tubular cooler which is used as a smelting tail gas cooler of a submerged arc furnace or an electric furnace. A dust sedimentation cabin and a dust discharging valve are arranged at the lower part of an air bottom-in cabin; and the bottom-in and top-out tubular cooler can be mounted behind a cyclone dust collector or can be directly mounted on a tail gas pipeline to omit the cyclone dust collector.

Description

technical field [0001] Dust-containing exhaust gas coolers such as submerged arc furnaces or submerged arc furnaces have been cooled by tubes from the top to the bottom, which saves some pipes, but the problem of dust accumulation and blockage of the tubes during long-term operation of the dust collector has been ignored. Background technique [0002] Dust-containing exhaust coolers such as submerged arc furnaces or submerged arc furnaces have always adopted the cooling method of top-in and bottom-out air tubes. After the dust in the exhaust gas on the upper part of the cooler decelerates, it is easy to settle on the top of the tubes, blocking the cooling tubes and increasing the ventilation resistance. The smelting smoke exhaust is not smooth, which affects the smelting operation environment. At the same time, the power of the environmental protection fan of the submerged arc furnace is increased, which increases the power consumption; and there is no space and position for ...
