Abstract
The utility model relates to a structure improvement and waste gas recovering and energy saving device for a cupola, belonging to the technical field of casting and environmental protection. The utility model is characterized in that a closed chimney internally provided with a heat absorption wind pipe (11), a secondary combustion chamber (52) and a dust remover, a waste gas recovering pipeline (8) connected with the secondary combustion chamber and an air box (34) at the lower part of the cupola on the top end of the chimney, a safety valve (53) and a recovering pressure blower fan (1) are upwards arranged on the upper part of a work platform (18) in turn; the air inlet of a heat absorption pipeline (11) is provided with a main blower fan, and the other end of the to the heat absorption pipeline (11) is connected with the air box (34). The utility model has the obvious effect of fully solving the problem of environmental pollution, and energy can be saved by 30 %.
Description
The utility model belongs to casting and environmental technology field.
The a large amount of flue dust of the cupola stack of foundry of factory discharging a few days ago, Main Ingredients and Appearance have carbon monoxide, sulfur dioxide, free carbon granules and hydrocarbon, serious environment pollution, infringement people's health.Although the unit that has has taked water curtain dedusting or electrostatic precipitation measure, effect is still undesirable.
The purpose of this utility model provides a kind of Cupola Construction improvement and waste gas reclaims energy saver, with thorough solution furnace cupola soot emissions problem of environment pollution caused.
The technical solution of the utility model is: establish the secondary combustion chamber (52) of heat absorption airduct (11) in workbench (18) top upwards is equipped with successively, chimney, the chimney top of band dust arrester sealing is connected to exhaust gas recycling tube road (8), easing valve (53), the recovery booster fan (1) that is connected with secondary combustion chamber and stove bottom bellows (34), heat absorbing conduit (11) air inlet (51) is equipped with main air blower, and the other end is connected with bellows (34).
The secondary combustion chamber lower case is provided with charge door (14).Secondary combustion chamber and chimney are the thorough steel construction of refractory brick brick.Also be provided with intilted striker plate (16) around the secondary combustion chamber bottom.
Heat absorption airduct (11) connects and composes for a plurality of " U " shape pipe.
The multilayer alternate dirt brick (5) that blocks straggly that chimney dust collecting device is with inner wall of stack links to each other all around constitutes.
The end that heat absorption airduct (11) and exhaust gas recycling tube (8) are connected with bellows (38) also communicates with pond (49).

2, free carbon granules and dust, a large amount of combustible and heat energy waste, and serious environment pollution, are very much unfortunate.Based on this point, the utility model has improved traditional Cupola Construction and be provided with secondary combustion chamber, heat absorption airduct above traditional furnace cupola work platform, waste gas burn once more liberated heat through the heat absorption airduct heat exchange, it is tropical excessively to turn back to bellows 34, molten iron, hot blast temperature is up to 600 ℃.Adopt the sealing pressurization to reclaim that chimney exhaust gas turns back to secondary combustion chamber and bellows, molten iron is crossed the torrid zone and burnt once more simultaneously, form the closed circulation repeat system, utilize heat energy from waste gas most effectively, thereby saved the energy greatly, reduced energy consumption.Through the trial run coke-iron-rate by original 1: (4～5) bring up to 1: (12～16), energy-conservation more than 30%, desulfurization is more than 90%, effect is fine, and promotional value is arranged very much.Not flammable dust in the chimney exhaust gas is then discharged with slag.Have a power failure when shutting down, waste gas and hot blast feed the pond can reduce furnace pressure raising furnace life.
Outstanding effect of the present utility model is to have solved the pollution of cupola stack toxic emission to environment fully, the heat in the chimney exhaust gas, combustible have been effectively utilized simultaneously, greatly having saved the energy reaches more than 30%, burnt iron reaches 1: (12～16), benefit is very much considerable, and promotional value is arranged very much.
