Abstract
The utility model discloses a jet flow type hot blast stove with a preheating device and a drying system. The drying system comprises a jet flow type hot blast stove (1), a preheater (2) and a drying machine (3), the jet flow type hot blast stove (1) is connected with the drying machine (3) through a hot blast chamber (13) by a connecting pipe, the jet flow type hot blast stove (1) is connected with the preheater (2) by a chimney (6), a jet flow groove (9) is formed between a combustion chamber (12) of the jet flow hot blast stove (1) and a smoke flue (8), and a smoke flue connecting pipe (7) is arranged between the combustion chamber (12) of the jet flow hot blast stove (1) and the smoke flue (8). The drying system can improve thermal efficiency, reduces pollution of emissions, fully utilizes waste heat of smoke, and saves flue consumption amount of the hot blast stove by about 20%.
Description
Technical field
The utility model relates to a kind of jet type hot blast stove and drying system that preheating device is housed.
Background technology
Common single flow Thermal Efficiency of Hot Blast Stoves is low, and cold wind enters in stove from stove top, is extracted out by air blast to the bottom, can not fully absorb furnace heat, a large amount of heats is discharged and slatterns, simultaneously, flue gas is come out of the stove a large amount of combustion residue bands to efflux and is placed in atmosphere, and is very large to the pollution of environment.
Summary of the invention
The purpose of this utility model aims to provide a kind of jet type hot blast stove and drying system that preheating device is housed, and has the advantages that to improve the thermal efficiency, energy-conserving and environment-protective.
for achieving the above object, a kind of jet type hot blast stove that preheating device is housed of the present utility model and drying system are by jet type hot blast stove, preheater and dryer form, jet type hot blast stove uses tube connector to be connected with dryer by hot air chamber, jet type hot blast stove is connected with preheater by chimney, between the combustion chamber of jet type hot blast stove and flue, jet efflux trough is set, the flue tube connector is set between the combustion chamber of jet type hot blast stove and flue, jet efflux trough two walls arrange aperture, the jet efflux trough bottom lock, preheater is a garden pipe that is enclosed within on stovepipe, leave certain space between inside pipe wall and smoke pipe outer wall, the jet current type hot air furnace bottom arranges cleaning door.
A kind of jet type hot blast stove and drying system that preheating device is housed of the present utility model compared with prior art has following excellent effect.
that a jet efflux trough is installed between combustion chamber and flue at jet type hot blast stove, groove two walls arrange many apertures, the bottom land sealing, rise to stove top after air is sent into by air blast from lower portion of furnace body and enter jet efflux trough, effect due to air blast, in groove, air has certain pressure, under this pressure-acting, just the aperture jet flow from groove two walls goes out, enter hot air chamber, then flow out body of heater and enter dryer, air is all absorbing the furnace heat intensification Zi entering body of heater in the process of discharging, and can contact with combustion chamber and flue outer wall when spraying by the jet efflux trough aperture, fully absorb the heat on combustion chamber and walling of flue and be rapidly heated, flue gas in the combustion chamber, enter flue by the flue tube connector, entering chimney by the stove bottom discharges, flue gas is taken the dust of combustion chamber out of, thereby major part stockpiles in the pollution of stove bottom minimizing to atmosphere, the heat of taking away in chimney, again reclaimed by economizer bank, it can improve the thermal efficiency, reduces emission and pollutes, and take full advantage of the waste heat of flue gas, the Fuel Consumption of saving hot-blast stove approximately 20%.
The setting of preheater makes between inside pipe wall and smoke pipe outer wall and leaves certain space, allows air enter from the top through this space, and the lower end is connected with air blast; After air blast started, cold air entered from the preheater top, is close to and sends hot-blast stove to after the smoke pipe outer wall is sucked by air blast, and cold air contacts with the smoke pipe outer wall when mobile, the waste heat that the absorption flue gas produces and heating up.
