Abstract
The invention relates to a flue gas afterheat multitube drying heating furnace, which consists of a feeding hole, a drying feed bin, a drying feed bin support, a discharge hole, air pipes and drying air pipes, wherein the air pipes are positioned at both ends of the drying feed bin; 2 to 10 layers of parallel or arc-shaped drying air pipes are arranged in the drying feed bin at certain intervals; and 3 to 20 parallel or arc-shaped drying air pipes are arranged on each layer, and the interval of every two drying air pipes on each layer is between 10 and 100 centimeters. The heating furnace can dry ores by fully utilizing flue gas afterheat, and has obvious energy-saving effect, and each ton of iron products can save electricity by 250 degrees; and taking a 16,500 KVA ore-smelting electric furnace with the annual output of 0.18 million tons of iron alloys as an example, the electricity is saved by 17.5 million degrees annually, and the cost is reduced by 7 million RMB.
Description
Technical field: fume afterheat multitube oven dry heating furnace belongs to metallurgical equipment.
Background technology: the ore drying plant that existing metallurgy industry uses mainly uses electric energy, has the problem that energy consumption is big, production cost is high.
Summary of the invention: the objective of the invention is to invent a kind of equipment that the high-temperature flue gas that produces is dried ore that makes full use of in smelting process, thereby reduce production costs for enterprise.
Fume afterheat multitube oven dry heating furnace, form by charging aperture, oven dry feed bin, oven dry feed bin support, discharging opening, airduct and oven dry airduct, airduct is positioned at the two ends of oven dry feed bin, the oven dry airduct is positioned at the oven dry feed bin,, according to the size of oven dry feed bin, oven dry has the oven dry airduct of the parallel or arc of 2-20 layer in the feed bin, every layer of oven dry airduct that the parallel or arc of 3-20 root is arranged, per two oven dry airducts of every layer are 10cm-100cm at interval.
Owing in the oven dry feed bin, increased several layers of oven dry airduct, the high-temperature flue gas that produces in the smelting process is guided in the oven dry airduct by airduct, by the heat that high-temperature flue gas in the oven dry airduct distributes the ore in the oven dry feed bin is dried, and ore is preheating to uniform temperature, reduce power consumption and shorten the duration of heat of ore in the smelting mine heat electric furnace, both utilized the high-temperature flue gas that produces in the smelting process, saved electric energy again, thereby for enterprise greatly reduces production cost, ton iron product economize on electricity 250 degree, with the 16500KVA ore-smelting electric furnace of producing 180000 tons of ferroalloys per year is example, and annual economize on electricity 1,750 ten thousand degree reduce cost 7,000,000 yuan.
Description of drawings: Fig. 1 is a positive view of the present invention, and Fig. 2 is a right cutaway view of the present invention.
Among the figure, 1 is charging aperture, and 2 are the oven dry feed bin, and 3 are oven dry feed bin support, and 4 is discharging opening, and 5 is airduct, and 6 are the oven dry airduct.
The specific embodiment: fume afterheat multitube oven dry heating furnace, form by charging aperture (1), oven dry feed bin (2), oven dry feed bin support (3), discharging opening (4), airduct (5) and oven dry airduct (6), airduct (5) is positioned at the two ends of oven dry feed bin (2), oven dry airduct (6) is positioned at oven dry feed bin (2), size according to oven dry feed bin (2), the oven dry airduct (6) that the parallel or arc of 2-20 layer arranged in oven dry feed bin (2), every layer of oven dry airduct (6) that the parallel or arc of 3-20 root is arranged, per two oven dry airducts (6) of every layer are 10cm-100cm at interval.
Embodiment 1: with the 16500KVA ore-smelting electric furnace is example, and 6 layers of oven dry airduct (6) are arranged in the oven dry feed bin (2), and every layer has 5 oven dry airducts (6), and per two oven dry airducts (6) of every layer are 60cm at interval.
During use; ore is transferred in the oven dry feed bin on time; be filled in the space between the oven dry airduct; the high-temperature flue gas that produces in the smelting process is guided in the oven dry airduct by airduct; utilize the heat oven dry ore that continual fume afterheat diffuses out in the oven dry airduct; and after ore is preheating to uniform temperature; be transported in the electric furnace by discharging opening; reach the purpose of oven dry and preheating ore; cause deduster after utilizing flue gas behind the waste heat to remove temperature; because of temperature reduces, the cloth bag that gathers dust there is the certain protection effect.
