Embodiment:
For clearly demonstrating the technical characterstic of this programme, below through embodiment, and combine its accompanying drawing, the present invention is set forth in detail.
Shown in figure, the present invention includes body of heater 1, be provided with water sealed tank 2 in the ingress, top of body of heater 1, bell 3 lower ends are stretched in the water sealed tank 2; Be provided with reduction reaction chamber 4 and cooling room 5 from top to bottom successively in body of heater 1 inside; Be provided with upper hopper 6 and following funnel 7 from top to bottom successively in the bottom of cooling room 5; The outside at upper hopper 6 and following funnel 7 is respectively equipped with windward chamber 8 and leeward chamber 9; Windward chamber 8 and leeward chamber 9 respectively be located at upper hopper 6 and be communicated with following funnel 7 inboard intermediary air-blast device 10 bottom blast inlets, the last blast inlet 11 of windward chamber 8 and leeward chamber 9 one sides and following blast inlet 12 respectively with cool off source of the gas and link to each other; Bottom at following funnel 7 is provided with discharge port 13, and chute 14 ends that discharge port 13 connects extend outfeed belt 15 material receiving ends.
Above outfeed belt 15, be provided with sponge iron retrieving arrangement 16.Can the finished product sponge iron that reduction obtains be separated with coke, satisfy the production needs of high-quality product.
Said sponge iron retrieving arrangement 16 is an electro-magnet.
In discharge port 13 places, be provided with the rotary seal valve.
Be provided with circular channel 17 in the outside, body of heater 1 middle part, 17 inboards, circular channel are communicated with cooling room 5 tops, and 17 outsides, circular channel link to each other with residual neat recovering system through pipeline; The last blast inlet 11 that is located at windward chamber 8 and leeward chamber 9 one sides and following blast inlet 12 respectively with residual neat recovering system in the recirculation blower air outlet link to each other.Can the heat energy that countercurrent flow in cooling room 5 obtains be delivered to residual neat recovering system and utilize, having solved traditional sponge iron production waste heat complementary energy can not recycle, for no reason the problem of waste.
On body of heater 1 sidewall on reduction reaction chamber 4 tops, be provided with somely to symmetrically arranged heat-accumulating burner 18, the outer end of heat-accumulating burner 18 links to each other with combustion control system respectively.When the temperature in the reduction reaction chamber 4 reduces; Can control through combustion control system and some heat-accumulating burner 18 carried out instantaneous reheat in reduction reaction chamber 4; To satisfy sponge iron oven dry finished product protocorm reductive condition, guarantee the abundant reduction of sponge iron oven dry finished product protocorm.
During use; Red-hot coke and sponge iron oven dry finished product protocorm packed into according to a certain percentage simultaneously go up batch can; Lift the feeding mouth place of body of heater 1 then by feeding system, open bell 3, the red-hot coke in the last batch can and sponge iron oven dry finished product protocorm is packed in the body of heater 1.Body of heater 1 interior red-hot coke and the sponge iron of packing into dried the reduction reaction chamber 4 that the finished product protocorm at first gets into body of heater 1 top; This place's furnace temperature is more than 1000 ℃; This position is absolute reducing atmosphere; Very help the inside reduction of sponge iron, final sponge iron oven dry finished product protocorm is accomplished the reducing process of built-in carbon sponge iron in reduction reaction chamber 4.When the temperature in the reduction reaction chamber 4 reduces; Can control some on body of heater 1 sidewall through combustion control system heat-accumulating burner 18 is carried out instantaneous reheat in reduction reaction chamber 4; To satisfy sponge iron oven dry finished product protocorm reductive condition, guarantee the abundant reduction of sponge iron oven dry finished product protocorm.Sponge iron oven dry finished product protocorm obtains the finished product sponge iron behind the certain hour high temperature reduction; The finished product sponge iron drops in the cooling room 5 of body of heater 1 bottom with the coke around it; The cold inertness gas that blows through the cooling source of the gas gets into windward chamber 8 and leeward chamber 9 through last blast inlet 11 and following blast inlet 12; Jet from bottom to top through air-blast device 10 again and get into finished product sponge iron and coke in the cooling room 5; Cold inert gas and finished product sponge iron and coke carry out countercurrent flow, and hot gas rises through the circular channel and 17 to get into residual neat recovering systems and carry out waste heat recovery and utilize.The hot gas that reclaims heat through residual neat recovering system becomes cold inertness gas again; Recirculation blower through residual neat recovering system gets into windward chamber 8 and leeward chamber 9 through last blast inlet 11 and following blast inlet 12 again, jets from bottom to top to send into again through air-blast device 10 again and carries out countercurrent flow in the cooling room 5.Finished product sponge iron behind the cold inertness gas converting heat and coke the warp discharge port 13 of funnel 7 bottoms are down come out of the stove, and the tapping temperature of finished product spongy mass is generally less than 180 ℃.The finished product sponge iron of coming out of the stove from discharge port 13 falls on the outfeed belt 15 through chute 14; When the sponge iron of producing is used for the less demanding low grade products of the quality of production; If the proportioning of sponge iron is fixed; Can not open the sponge iron retrieving arrangement 16 of outfeed belt 15 tops, finished product sponge iron on the outfeed belt 15 not done with cold coke separated, directly be admitted to blast furnace and get final product; When the sponge iron of producing is used for the demanding expensive goods of the quality of production, open the sponge iron retrieving arrangement 16 of outfeed belt 15 tops, utilize electro-magnet than strong suction, with the sucking-off of finished product sponge iron, deliver to corresponding smelting device through other conveyer again.
Adopt device for producing sponge iron of the present invention, simple in structure, reasonable in design, volume is little, uses easy to operately, invests little; And; Produce all inflammable gass and the high temperature sensible heat (more than 1000 ℃) that produce in the sponge iron process and all can obtain efficient and rational utilization; Produce waste heat complementary energy and can not recycle thereby solved traditional sponge iron, the problem of waste has for no reason reached the purpose of energy-saving and emission-reduction.
Above-mentioned embodiment can not be as the restriction to protection domain of the present invention, and for the technician in present technique field, any alternate modification or conversion that embodiment of the present invention is made all drop in protection scope of the present invention.
