The technical scheme that the present invention is taked for the technical solution problem is:
A kind of graphite electrode high-pressure impregnation operation roasting product heat hot air circulating system, comprise circulating fan, heating part, heat exchange section and smoke evacuation part, described heating part comprises gas burner, heating furnace, branch gas tank, preheating furnace and plenum chamber, pass through hot air flue UNICOM between described heating furnace and the branch gas tank, be provided with branch gas control valve between described minute gas tank and the preheating furnace, be provided with the gas collection control valve between described preheating furnace and the plenum chamber; Described heat exchange section comprises air blast and heat exchanger, by air blast cold air that is blown into and the portion of hot gas that divides gas tank to tell, after heat exchanger heats, offers the gas burner hot-air; Described smoke evacuation part comprises smoke exhaust fan and exit flue, is discharged by exit flue through smoke exhaust fan from the flue gas that heat exchanger ejects.
Between described circulating fan and the plenum chamber, divide between gas tank and the heat exchanger, between heat exchanger and the gas burner all by hot air flue UNICOM.
Described minute gas control valve and gas collection control valve all are made up of three groups of control valves.
Positive beneficial effect of the present invention is:
1, graphite electrode high-pressure impregnation operation roasting product heat hot air circulating system of the present invention, by the adjusting of minute gas control valve and gas collection control valve, the heating-up temperature of electrode product in the preheating furnace, homogeneous heating, impregnating effect is guaranteed.
2, graphite electrode high-pressure impregnation operation roasting product heat hot air circulating system of the present invention, by air blast cold air that is blown into and the portion of hot gas that divides gas tank to tell, after heat exchanger heats, offer the gas burner hot-air, improve the ignition temperature of coal gas, saved the energy.
3, graphite electrode high-pressure impregnation operation of the present invention roasting product heat hot air circulating system, the hot blast in its plenum chamber are recycled blower fan and are blown into heating furnace and reheat recyclingly, have saved the energy.
4, graphite electrode high-pressure impregnation operation of the present invention bakes product heat hot air circulating system, has reduced the exhaust gas temperature and the exhaust smoke level of chimney, has reduced air discharge.
5, graphite electrode high-pressure impregnation operation roasting product heat hot air circulating system of the present invention, simple to operate by the horizontal vertical tank preheating roasting product circulation mode of heating that changes into commonly used at present, the production efficiency height, small investment, operating cost is lower.
Four, description of drawings:
Fig. 1 is a structural representation of the present invention.
Five, the specific embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing:
Referring to Fig. 1, each sequence number is expressed as follows among the figure: the 1-gas burner, and the 2-heating furnace, 3-divides gas tank, and 4-divides the gas control valve, the 5-preheating furnace, 6-plenum chamber, 7-circulating fan, 8-heat exchanger, the 9-smoke exhaust fan, 10-exit flue, 11-air blast, 12-gas collection control valve.
A kind of graphite electrode high-pressure impregnation operation roasting product heat hot air circulating system, comprise circulating fan 7, heating part, heat exchange section and smoke evacuation part, described heating part comprises gas burner 1, heating furnace 2, divides gas tank 3, preheating furnace 5 and plenum chamber 6, pass through hot air flue UNICOM between described heating furnace 2 and the branch gas tank 3, be provided with branch gas control valve 4 between described minute gas tank 3 and the preheating furnace 5, be provided with gas collection control valve 12 between described preheating furnace 5 and the plenum chamber 6; Described heat exchange section comprises air blast 11 and heat exchanger 8, by air blast 11 cold air that is blown into and the portion of hot gas that divides gas tank 3 to tell, after heat exchanger 8 heating, offers gas burner 1 hot-air; Described smoke evacuation part comprises smoke exhaust fan 9 and exit flue 10, is discharged by exit flue 10 through smoke exhaust fan 9 from the flue gas that heat exchanger 8 ejects.Between described circulating fan 7 and the plenum chamber 6, divide between gas tank 3 and the heat exchanger 8, between heat exchanger 8 and the gas burner 1 all by hot air flue UNICOM, described minute gas control valve 4 and gas collection control valve 12 all are made up of three groups of control valves.
