Abstract
The present invention relates to the energy saver that a kind of silicon system mineral heating furnace flue recycles, is be heated 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 system mineral heating furnace flue to be provided with circulating fan, gas approach pipeline and gas approach pipeline valve, exhanst gas outlet pipeline and exhanst gas outlet pipeline valve.The invention has the beneficial effects as follows: compared with existing mixing air technology, both can obtain more mixed flue gas amount, improve utilization rate of waste heat, the power load of mineral hot furnace institute of open smoke hood type silicon system draught fan matching can be reduced again, thus reach the effect of energy-saving and emission-reduction.
Description
Technical field:
The present invention relates to the energy saver of mineral hot furnace UTILIZATION OF VESIDUAL HEAT IN, specifically refers to the energy saver that open smoke hood type silicon system mineral heating furnace flue recycles.
Background technology:
At present, in the production process of open smoke hood type silicon system mineral hot furnace, in petticoat pipe, a large amount of CO gas is overflowed in material face, and meet air namely to burn, after burning, on material face, flue-gas temperature reaches more than 800 DEG C, containing dust (main chemical compositions silica) such as a large amount of silicon powders in flue gas, this dust has very strong caking property when flue gas more than 500 DEG C.For this reason, existing open smoke hood type silicon system mineral heating furnace flue is heated Noodles residual heat using device, such as waste heat boiler and waste heat wind furnace etc., all adopt the air mixed flue gas in air, cause mixed flue gas to enter Noodles residual heat using device of being heated (as waste heat boiler, waste heat wind furnace etc.) with about 450 DEG C.In addition, this series is heated the deashing device of Noodles residual heat using device (as waste heat boiler, waste heat wind furnace etc.) self all supporting necessity.
Existing open smoke hood type silicon system mineral heating furnace flue is heated Noodles residual heat using device (as waste heat boiler, waste heat wind furnace etc.), adopt large negative pressure induced wind mode by the large quantity of air mixed flue gas in air, about reducing mixed flue-gas temperature to 450 DEG C, the dust such as the silicon powder technical requirement that caking property is less below 500 DEG C can be met.There is critical defect in above-mentioned current art method: the first causes a large amount of waste heat loss by discharging after large quantity of air heating; Its two be large quantity of air certainly will increase open smoke hood type silicon system mineral hot furnace the load of supporting dedusting fan, cause mass energy consumption; Its three, air themperature and density are comparatively large by four seasons spring, summer, autumn and winter ambient influnence, comparatively large by regional impacts such as the four corners of the world, have a strong impact on utilization rate of waste heat.Therefore, how providing a kind of energy saver opening smoke hood type silicon system mineral heating furnace flue and recycle, 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 energy saver opening smoke hood type silicon system mineral heating furnace flue and recycle, reaching the effect of energy-saving and emission-reduction.
Opening the energy saver that smoke hood type silicon system mineral heating furnace flue recycles, is be heated 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 system mineral heating furnace flue to be provided with circulating fan, gas approach pipeline and gas approach pipeline valve, exhanst gas outlet pipeline and exhanst gas outlet pipeline valve; Described gas approach pipeline and gas approach pipeline valve and the open smoke hood type silicon system 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 the open smoke hood type silicon system 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: compared 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 system mineral hot furnace the power load of supporting dedusting fan, thus reach the effect of energy-saving and emission-reduction.
Accompanying drawing illustrates:
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 the energy saver that smoke hood type silicon system mineral heating furnace flue recycles, is be heated 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 system mineral heating furnace flue to be 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; Gas approach pipeline 3 and gas approach pipeline valve 2 and the open smoke hood type silicon system 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 the open smoke hood type silicon system 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, regulate open smoke hood type silicon system mineral hot furnace dedusting fan, with cold air mixing high-temperature flue gas, mixed flue gas temperature is reached 450 degree (dust such as silicon powder contained by flue gas has the less feature of caking property), then mixed flue gas enters Noodles residual heat using device of being heated (as waste heat boiler, waste heat wind furnace etc.), and last low-temperature flue gas drains into deduster through open smoke hood type silicon system mineral hot furnace dedusting fan.
During unlatching, close bypass flue valve, start circulating fan 1, open gas approach pipeline valve 2 and exhanst gas outlet pipeline valve 4 simultaneously, regulate open smoke hood type silicon system mineral hot furnace dedusting fan, make to carry out tiny structure or pressurized firing in petticoat pipe, large quantity of air and dust is prevented to be mixed into flue gas, thus acquisition high-temperature flue gas, the present invention is with low-temperature flue gas mixing high-temperature flue gas, mixed flue gas temperature is reached 450 degree (dust such as silicon powder contained by flue gas has the less feature of caking property), then mixed flue gas enters 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 high-temperature flue gas through apparatus of the present invention circulation, form mixed flue gas (450 degree) and reenter Noodles residual heat using device of being heated (as waste heat boiler, waste heat wind furnace etc.), another part low-temperature flue gas then enters open smoke hood type silicon system mineral hot furnace dedusting fan and drains into deduster.
