Abstract

A sintering furnace type cooling device relates to the technology field of sintering cooling devices. An outlet of a sintering machine is provided with a single roll crusher; an outlet of the single roll crusher is provided with a hot sinter screen; the hot sinter screen is connected with an inlet of a chute; an outlet of the chute is connected with a furnace opening of a cooling furnace; a distributing device is arranged inside the furnace opening of the cooling furnace; a ventilation device is arranged at the bottom of the cooling furnace; a discharging device is connected under the ventilation device; a belt conveyer is arranged under the discharging device; the cooling furnace comprises a pre-store area which is arranged on the upper portion, a cooling area which is arranged on the lower portion and an annular flue area which is arranged on the periphery of the pre-store area; radial supporting columns which are integrally and radially distributed are arranged at the bottom of the annular flue area; a high-temperature flue gas adjustment plate is coated on two adjacent radial supporting columns; and the high-temperature flue gas adjustment plate is capable of sliding along a diametrical direction of the annular flue. The sintering furnace type cooling device has the advantages of effectively overcoming the defects that an existing sintering cooling system is serious in air infiltration and low in waste heat utilization rate, achieving efficient heat replacement, improving the temperature of the flue gas and reducing energy consumption in cooling.

Description

technical field [0001] The invention relates to the technical field of sinter cooling equipment, in particular to a sinter furnace type cooling device. Background technique [0002] my country is a country that consumes a lot of energy. In order to vigorously promote energy-saving and environmental protection technologies and improve the comprehensive utilization efficiency of energy, the country has proposed a series of encouraging and preferential policies. The iron and steel industry is a large energy consumer in my country, accounting for about 15% of the total energy consumption in the country. In the process of iron and steel production, the energy consumption of the sintering process ranks second, and the sensible heat of sintering production in sintering production accounts for more than 40% of the total heat consumption. Energy saving in sintering is very important. Efficient recycling and utilization of sensible heat of sintering is an effective way to improve energ...
