Description
Technical field
A kind of residual neat recovering system for the annealing of tunnel type orientation silicon steel continuous high temperature of the utility model, belongs to oriented silicon
Steel annealing furnace technical field.
Background technology
Existing residual neat recovering system is installed on burner hearth side due to heat exchanging pipe, using coil of strip and the outer cover pair of red heat
Heat exchange cold water pipes carry out radiant heat exchange, and when coil of strip and inner cover temperature reduce, 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 that pipe is heated by air is substantially poor compared with top.
Utility model content
The utility model overcomes the deficiency of prior art presence, there is provided a kind of continuously high for tunnel type orientation silicon steel
The residual neat recovering system of temperature annealing, solves strip in annealing cooling, and the relatively low problem of the heat recovery efficiency giving out makes
Waste heat is more fully exchanged.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is：One kind is used for tunnel type oriented silicon
The residual neat recovering system of steel continuous high temperature annealing, including ground, body of heater, gas skirt, heat exchanger and pump-line, described body of heater is solid
Surely it is arranged on ground, the top of described body of heater is provided with gas skirt, described gas skirt is used for collecting the hot gas in body of heater, described
Gas skirt is connected on heat exchangers by pipeline, carries out heat exchange, and described heat exchanger is arranged on body of heater, and described pump-line sets
Put on the escape pipe of heat exchanger, the cold air after exchanging is drained.
Described heat exchanger is fixedly installed on body of heater by heat exchanger support.
Centrifugation ventilating draught fan is installed 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 lye, described heat exchanger is provided with cooling alkali liquor inlet and
Cooling lye export, described cooling alkali liquor inlet and cooling lye export are connected to one by pipeline and cooling NaOH solution circulating pump
Rise, form cooling alkali lye circulation.
The utility model compared with prior art has an advantageous effect in that：The utility model heat exchange efficiency is higher, is discharged to
Extraneous air themperature reduces, and the heat that upstream device needs is fully able to meet.
Brief description
Below in conjunction with the accompanying drawings the utility model is described further.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
In figure：1 be ground, 2 be body of heater, 3 be gas skirt, 4 be heat exchanger, 5 be pump-line, 6 be heat exchanger support, 7
For cooling alkali liquor inlet, 8 for cooling down lye export.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of waste heat recovery for the annealing of tunnel type orientation silicon steel continuous high temperature of the utility model
System, including ground 1, body of heater 2, gas skirt 3, heat exchanger 4 and pump-line 5, described body of heater 2 is fixedly installed on ground 1, institute
The top stating body of heater 2 is provided with gas skirt 3, and described gas skirt 3 is used for collecting the hot gas in body of heater 2, and described gas skirt 3 passes through pipe
Road is connected on heat exchanger 4, carries out heat exchange, and described heat exchanger 4 is arranged on body of heater 2, and described pump-line 5 is arranged on heat exchange
On the escape pipe of device 4, the cold air after exchanging is drained.
Described heat exchanger 4 is fixedly installed on body of heater 2 by heat exchanger support 6.
Centrifugation ventilating draught fan is installed on described pump-line 5 additional, the air in heat exchanger 4 produces suction.
It is full of cooling alkali lye in heat exchanging pipe in described heat exchanger 4, described heat exchanger 4 is provided with cooling alkali liquor inlet
7 by pipeline and cool down NaOH solution circulating pump connection with cooling lye export 8 with cooling lye export 8, the described alkali liquor inlet 7 that cools down
Together, form cooling alkali lye circulation.
The operation principle of utility model：When stove vehicle-mounted coil of strip by isolating door reach cooled region after, the coil of strip of red heat
And outer cover can be radiated and heat transfer to the air of furnace wall and surrounding, the furnace wall being heated equally also can circumference air.
Substantial amounts of hot-air rising gathers in 1# gas skirt and 2# gas skirt, installs 1 centrifugation ventilating draught fan at pump-line 5 additional,
Air in meeting heat exchanger after blower fan work produces suction.Hot-air enters in heat exchanger, with the heat exchange row in heat exchanger
Pipe carries out heat exchange, and the air after cooling is discharged in air.
The course of work of the present utility model：Start centrifugation ventilating draught fan, allow hot-air to enter inside heat exchanger, start cooling
NaOH solution circulating pump, allows cooling alkali lye enter heat exchanging pipe.
Then alkali lye elder generation after the utility model heat exchange pumps into pipeline by water pump by water pump pump in 1#, 2# boiler again
