Abstract
The invention relates to an energy saving device for cyclic utilization of the smoke of an open smoke hood type silicon submerged arc furnace. According to the energy saving device for cyclic utilization of the smoke of the open smoke hood type silicon submerged arc furnace, a circulating draught fan, a smoke inlet pipeline, a smoke inlet pipeline valve, a smoke outlet pipeline and a smoke outlet pipeline valve are arranged between a smoke inlet and a smoke outlet of a heated surface quasi water heat utilization device such as a waste heat boiler or a waste heat draft furnace. Compared with an existing air mixing technology, the energy saving device for cyclic utilization of the smoke of the open smoke hood type silicon submerged arc furnace has the advantages that a larger amount of mixed smoke can be obtained, the waste heat utilization rate is increased, the power load of the draught fan used in cooperation with the open smoke hood type silicon submerged arc furnace can be lowered, and thus the effects of energy saving and emission reduction are achieved.
Description
Technical field:
The present invention relates to the energy saver of mineral hot furnace UTILIZATION OF VESIDUAL HEAT IN, specifically refers to that open smoke hood type silicon is the energy saver that mineral heating furnace flue recycles.
Background technology:
At present, open smoke hood type silicon is in the production process of mineral hot furnace, in petticoat pipe, material face overflows a large amount of CO gas, and meeting air burns, after burning, on material face, flue-gas temperature reaches more than 800 DEG C, in flue gas, contain the dust (main chemical compositions silica) such as a large amount of silicon powders, this dust has very strong caking property in the time that flue gas is more than 500 DEG C.For this reason, existing open smoke hood type silicon is the mineral heating furnace flue Noodles residual heat using device of being heated, for example waste heat boiler and waste heat wind furnace etc., all adopt the air mixed flue gas in atmosphere, cause mixed flue gas to enter the Noodles residual heat using device of being heated (as waste heat boiler, waste heat wind furnace etc.) with 450 DEG C of left and right.In addition, this series all deashing devices of supporting necessity of Noodles residual heat using device (as waste heat boiler, waste heat wind furnace etc.) self that are heated.
Existing open smoke hood type silicon is the mineral heating furnace flue Noodles residual heat using device (as waste heat boiler, waste heat wind furnace etc.) of being heated, adopt large negative pressure induced wind mode by the large quantity of air mixed flue gas in atmosphere, to reduce mixed flue-gas temperature to 450 DEG C left and right, can meet the dust such as silicon powder 500 DEG C of technical requirements that following caking property is less.There is critical defect in above-mentioned existing technical method: the first causes a large amount of waste heat losses by discharging after large quantity of air heating; Its two be large quantity of air certainly will increase open smoke hood type silicon be mineral hot furnace the load of supporting dedusting fan, cause mass energy consumption; Its three, air themperature and density are subject to four seasons spring, summer, autumn and winter ambient influnence larger, are subject to the regional impacts such as the four corners of the world larger, have a strong impact on utilization rate of waste heat.Therefore, how a kind of smoke hood type silicon of opening is provided is the energy saver that mineral heating furnace flue recycles, and is the object that the present invention studies.
Summary of the invention:
For overcoming the deficiencies in the prior art, the invention provides a kind of smoke hood type silicon of opening is the energy saver that mineral heating furnace flue recycles, and has reached the effect of energy-saving and emission-reduction.
Opening smoke hood type silicon is the energy saver that mineral heating furnace flue recycles, and is to be that mineral heating furnace flue is heated and is provided with circulating fan, gas approach pipeline and gas approach pipeline valve, exhanst gas outlet pipeline and exhanst gas outlet pipeline valve between the gas approach of Noodles residual heat using device (as waste heat boiler, waste heat wind furnace etc.) and exhanst gas outlet at open smoke hood type silicon; Described gas approach pipeline and gas approach pipeline valve and open smoke hood type silicon are that the mineral heating furnace flue Noodles residual heat using device exhanst gas outlet that is heated is connected; Described exhanst gas outlet pipeline and exhanst gas outlet pipeline valve and open smoke hood type silicon are that the mineral heating furnace flue Noodles residual heat using device gas approach that is heated is connected; Described circulating fan is connected with exhanst gas outlet pipeline valve with gas approach pipeline valve simultaneously.
The invention has the beneficial effects as follows: compare with existing mixing air technology, mixing low temp flue gas both can obtain more mixed flue gas amount, improve utilization rate of waste heat, can reduce again open smoke hood type silicon and be mineral hot furnace the power load of supporting dedusting fan, thereby reach the effect of energy-saving and emission-reduction.
Brief description of the drawings:
Fig. 1 is device schematic diagram of the present invention;
Wherein: circulating fan 1, gas approach pipeline valve 2, gas approach pipeline 3, exhanst gas outlet pipeline valve 4, exhanst gas outlet pipeline 5.
Detailed description of the invention:
1 couple of the present invention is further analyzed with reference to the accompanying drawings below;
Opening smoke hood type silicon is the energy saver that mineral heating furnace flue recycles, and is to be that mineral heating furnace flue is heated and is provided with circulating fan 1, gas approach pipeline valve 2, gas approach pipeline 3, exhanst gas outlet pipeline valve 4 and exhanst gas outlet pipeline 5 between the gas approach of Noodles residual heat using device (as waste heat boiler, waste heat wind furnace etc.) and exhanst gas outlet at open smoke hood type silicon; Gas approach pipeline 3 and gas approach pipeline valve 2 and open smoke hood type silicon are that the mineral heating furnace flue Noodles residual heat using device exhanst gas outlet that is heated is connected; Exhanst gas outlet pipeline 5 and exhanst gas outlet pipeline valve 4 and open smoke hood type silicon are that the mineral heating furnace flue Noodles residual heat using device gas approach that is heated is connected; Circulating fan 1 is connected with exhanst gas outlet pipeline valve 4 with gas approach pipeline valve 2 simultaneously.
Before unlatching, close gas approach pipeline valve 2 and exhanst gas outlet pipeline valve 4, close bypass flue valve simultaneously, regulating open smoke hood type silicon is mineral hot furnace dedusting fan, with cold air mixing high-temperature flue gas, make mixed flue gas temperature reach 450 degree (dust such as silicon powder that flue gas is contained has the feature that caking property is less), then mixed flue gas enters the Noodles residual heat using device of being heated (as waste heat boiler, waste heat wind furnace etc.), and last low-temperature flue gas is that mineral hot furnace dedusting fan drains into deduster through open smoke hood type silicon.
When unlatching, close bypass flue valve, start circulating fan 1, open gas approach pipeline valve 2 and exhanst gas outlet pipeline valve 4 simultaneously, regulating open smoke hood type silicon is mineral hot furnace dedusting fan, make to carry out in petticoat pipe micro-negative pressure or pressurized firing, prevent that large quantity of air and dust from sneaking into flue gas, thereby acquisition high-temperature flue gas, the present invention is with low-temperature flue gas mixing high-temperature flue gas, make mixed flue gas temperature reach 450 degree (dust such as silicon powder that flue gas is contained has the feature that caking property is less), then mixed flue gas enters the Noodles residual heat using device of being heated (as waste heat boiler, waste heat wind furnace etc.), at smoke outlet, a part of low-temperature flue gas is mixed to high-temperature flue gas through apparatus of the present invention circulation, form mixed flue gas (450 degree) and reenter the Noodles residual heat using device of being heated (as waste heat boiler, waste heat wind furnace etc.), it is that mineral hot furnace dedusting fan drains into deduster that another part low-temperature flue gas enters open smoke hood type silicon.
