Description
Technical field
The present invention, for the residual neat recovering system of tunnel type orientation silicon steel continuous high temperature annealing, belongs to orientation silicon steel annealing furnace
Technical field.
Background technology
Existing residual neat recovering system is installed on burner hearth side due to heat exchanging pipe, utilizes coil of strip and the outer housing pair of red heat
Heat exchange cold water pipes carries out radiant heat exchange, when coil of strip and inner cover temperature reduce, and radianting capacity substantially weakens, and heat transfer effect becomes
Difference.And due to the less reason of hot-air density, so cooling section hot-air is largely focused on roof of the furnace, sidepiece radiates
The ability substantially relatively top that pipe is heated by air is poor.
Summary of the invention
Instant invention overcomes the deficiency that prior art exists, it is provided that a kind of tunnel type orientation silicon steel continuous high temperature that is used for moves back
The residual neat recovering system of fire, solves strip steel when annealing cooling, and the problem that the heat recovery efficiency that gives out is relatively low makes waste heat
More fully exchanged.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: the highest for tunnel type orientation silicon steel
The residual neat recovering system of temperature annealing, including ground, body of heater, gas skirt, heat exchanger and pump-line, described furnace bottom is fixedly installed on
On ground, the top of described body of heater is provided with gas skirt, and described gas skirt is for collecting the steam in body of heater, and described gas skirt leads to
Crossing pipeline to connect on heat exchangers, carry out heat exchange, described heat exchanger is arranged on body of heater, and described pump-line is arranged on heat exchange
On the escape pipe of device, the cold air after exchange is drained.
Described heat exchanger is fixedly installed on body of heater by heat exchanger support.
Installing centrifugal ventilating draught fan on described pump-line additional, the air in heat exchanger produces suction.
In heat exchanging pipe in described heat exchanger be full of cooling alkali liquor, described heat exchanger is provided with cooling alkali liquor inlet and
Cooling alkali liquor outlet, described cooling alkali liquor inlet and cooling alkali liquor outlet are connected to one by pipeline and cooling NaOH solution circulating pump
Rise, form cooling alkali liquor circulation.
The present invention compared with prior art has the beneficial effect that heat exchange efficiency of the present invention is higher, is discharged to the sky in the external world
Temperature reduces, and the heat that upstream device needs is fully able to meet.
Accompanying drawing explanation
The present invention is described further below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the side view of the present invention.
In figure: 1 be ground, 2 for body of heater, 3 for gas skirt, 4 for heat exchanger, 5 for pump-line, 6 for heat exchanger support, 7
For cooling alkali liquor inlet, 8 for cooling alkali liquor outlet.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the residual neat recovering system that the present invention anneals for tunnel type orientation silicon steel continuous high temperature, including
Ground 1, body of heater 2, gas skirt 3, heat exchanger 4 and pump-line 5, described furnace bottom 2 is fixedly installed on ground 1, described body of heater 2
Top is provided with gas skirt 3, and described gas skirt 3 is for collecting the steam in body of heater 2, and described gas skirt 3 is connected to by pipeline
On heat exchanger 4, carrying out heat exchange, described heat exchanger 4 is arranged on body of heater 2, and described pump-line 5 is arranged on going out of heat exchanger 4
On trachea, the cold air after exchange is drained.
Described heat exchanger 4 is fixedly installed on body of heater 2 by heat exchanger support 6.
Installing centrifugal ventilating draught fan on described pump-line 5 additional, the air in heat exchanger 4 produces suction.
Heat exchanging pipe in described heat exchanger 4 is full of cooling alkali liquor, described heat exchanger 4 is provided with cooling alkali liquor inlet
7 export 8 with cooling alkali liquor outlet 8, described cooling alkali liquor inlet 7 and cooling alkali liquor is connected by pipeline and cooling NaOH solution circulating pump
Together, cooling alkali liquor circulation is formed.
The operation principle of invention: when stove vehicle-mounted coil of strip arrived after cooled region by isolating door, the coil of strip of red heat and outer
Furnace wall and air around can be radiated and heat transfer by cover, and the furnace wall being heated the most also can the air of circumference.In a large number
Hot-air rise gather in 1# gas skirt and 2# gas skirt, at pump-line 5, install 1 centrifugal ventilating draught fan, blower fan additional
After work, the air in meeting heat exchanger produces suction.Hot-air enters in heat exchanger, enters with the heat exchanging pipe in heat exchanger
Row heat exchange, the air after cooling is discharged in air.
The work process of the present invention: start centrifugal ventilating draught fan, allows hot-air enter inside heat exchanger, starts cooling alkali liquor
Circulating pump, allows cooling alkali liquor enter heat exchanging pipe.
Alkali liquor after heat exchange of the present invention first by water pump pump to 1#, 2# boiler, is pumped into pipeline circulation by water pump the most again
System, arrives separately at 650 decarburization magnesium oxide lines, wide plate decarburization line, magnesium oxide 1# production line, these 4 lifes of magnesium oxide 2# production line
Producing line, the heat alkali liquid needed for providing for each production line, the alkali liquor that each production line is finished is back to alkali liquor pond, the most again by water pump pump
Return to heat exchanger, form alkali liquor circulation.
