Accompanying drawing explanation
Fig. 1 is a kind of tail gas from electric furnace energy-saving emission-reducing apparatus of the utility model structural representation.
Detailed description of the invention
The utility model provides a kind of tail gas from electric furnace energy-saving emission-reducing apparatus, for making the purpose of this utility model, technical scheme more clear, further describes below to the utility model.
Refer to Fig. 1, Fig. 1 is a kind of tail gas from electric furnace energy-saving emission-reducing apparatus of the utility model preferably structural representation.It comprises: the first maintenance water seal arrangement (3) being connected to venturi condenser (1), be connected to the vavuum pump (4) of the first maintenance water seal arrangement (3), be connected to the gas-liquid separator (5) of vavuum pump (4), be connected to the second maintenance water seal arrangement (6) of gas-liquid separator (5), be connected to the back-fire relief water seal arrangement (7) of the second maintenance water seal arrangement (6), be connected to the heating equipment (10) of back-fire relief water seal arrangement (7), be connected to the combustion air blower fan (9) of heating equipment (10).
The utility model utilizes the draft effect of vavuum pump (4), tail gas from electric furnace (containing CO concentration more than 90%) is caused heating equipment (10) replacement raw coal combustion and carries out material drying to provide heat, thus reach energy-saving and emission-reduction object.
Described venturi condenser (1) connects the emptying chimney of a tail gas (2).When needs are recycled, close the valve of the emptying chimney of tail gas (2), tail gas enters into the first maintenance water seal arrangement (3) and enters into follow-up treatment facility successively.During without the need to recycling, then from venturi condenser (1) tail gas out, directly emptying from the emptying chimney of tail gas (2).Gas-liquid separator (5) utilizes the effect of gravity, realizes gas and moisture, being separated of dust.In electric furnace production process, the tolerance of output is calculated and measured, thus select suitable vacuum pump pressure and flow, line size.Described heating equipment can be that such as rotary kiln, holding furnace, rectifying column etc. need hot furnace kiln body.
The course of work of the present utility model is as follows:
It is combustion-supporting that a small amount of dedusting → vavuum pump (4) of venturi condenser (1) dedusting → the first maintenance water seal arrangement (3) provides transmitting power → gas-liquid separator (5) removing tail gas entrapped moisture → the second maintenance water seal arrangement (6) second dehydration, a small amount of dedusting → tail gas breaks through back-fire relief water seal arrangement (7) → heating equipment (10) ignition → combustion air blower fan (9) air distribution.
