Abstract
The utility model discloses a hot blast stove system, which comprises a stove body (8), a heat exchanger (6), a tail gas pipe (3) and a hot blast pipe (1). An air outlet (5) of the heat exchanger is connected with the hot blast pipe (1). One end of the tail gas pipe (3) is connected with the heat exchanger (6), and the other end thereof is connected with a dust remover (7). The hot blast stove system is characterized in that an axial flow fan (2) is arranged in the hot blast pipe (1) of a hot blast stove; and a jacket (4) is arranged outside the tail gas pipe (3). Cold air in the jacket is preheated through the tail gas pipe and then fed in the hot blast stove as new air source for heating, and then the hot air is fed to the required position, so that the final exhaust temperature of the tail gas is reduced to 100 degrees or so, thereby saving a great quantity of energy, preventing high temperature from affecting the system and prolonging the service life of the system. In addition, as the axial flow fan is additionally arranged in the hot blast pipe of the hot blast stove, the temperature of the air flow can be uniform, thereby obviously improving the stability of product quality, wherein the product passing rate is increased to more than 95 per cent from the original less than 90 per cent.
Description
Technical field
The utility model belongs to chemical machinery field, is specifically related to a kind of hot blast stove system.
Background technology
The tail gas of about 300 ℃ in hot-blast stove directly emits in the prior art, serious waste the energy.In addition, common 1 hot-blast stove will use for 2 drying towers, but because 2 actual serviceability temperature differences of drying tower, wherein 1 drying tower needs temperature on the low side, for addressing this problem, the directly mode of supplements cold in warm-air pipe is arranged, but all influence product quality because of gas flow temperature is inhomogeneous.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point a kind of hot blast stove system is provided.
The purpose of this utility model realizes by following measure:
A kind of hot blast stove system comprises body of heater, heat exchanger, offgas duct and warm-air pipe, and the heat exchanger gas outlet connects warm-air pipe, one end of offgas duct connects heat exchanger, the other end connects deduster, it is characterized in that in the warm-air pipe of hot-blast stove axial flow blower being set, and chuck is installed outside offgas duct.Cool air inlet is set on warm-air pipe, and axial flow blower is fixed on the warm-air pipe inwall.
The beneficial effects of the utility model compared with the prior art: cold air is sent in the hot-blast stove as a kind of new source of the gas after the offgas duct preheating and is heated in the chuck, then hot gas is delivered to desired area, the final exhaust temperature of tail gas is reduced to about 100 ℃ like this, a large amount of energy have been saved, avoided the influence of high temperature simultaneously, and can prolong the service life of equipment equipment.In addition, in the hot air furnace hot air pipe axial flow blower is set, makes gas flow temperature keep evenly obviously having improved the stability of product quality, product percent of pass is from original rising to more than 95% less than 90%.
Description of drawings
Fig. 1 is the utility model hot blast stove system schematic diagram.
Fig. 2 is the utility model warm-air pipe schematic diagram.
Among the figure, 1 is warm-air pipe, and 2 is axial flow blower, and 3 is offgas duct, and 4 is chuck, and 5 is the heat exchanger gas outlet, and 6 is heat exchanger, and 7 is deduster, and 8 is body of heater, and 9 is air-introduced machine, and 10 is air blast, and 11 is cool air inlet.
The specific embodiment
A kind of hot blast stove system, comprise body of heater 8, heat exchanger 6, offgas duct 3 and warm-air pipe 1,5 connect warm-air pipe 1 in the heat exchanger gas outlet, one end of offgas duct 3 connects heat exchanger 6, the other end connects deduster 7, it is characterized in that in the warm-air pipe 1 of hot-blast stove, axial flow blower 2 being set, chuck 4 is installed outside offgas duct 3.Cool air inlet 11 is set on warm-air pipe 1, and axial flow blower 2 is fixed on warm-air pipe 1 inwall.
When operation, the new source of the gas of the interior cold air of chuck conduct after the offgas duct preheating is sent in the hot-blast stove and is heated on the offgas duct, then hot gas is delivered to desired area, and the final exhaust temperature of tail gas is reduced to about 100 ℃ like this.In addition, the axial flow blower in the hot air furnace hot air pipe makes gas flow temperature keep evenly the stability of improving the quality of products.
