Certain distance;Upper sheaf space includes dividing plate, and one end of dividing plate is sealed against on supporting plate, and the other end seals against
In the inner top wall and front and back walls of body of heater, so as to which upper sheaf space is separated into leftward space and rightward space;In upper sheaf space
Leftward space in configure hot blast generating means, blower fan is provided with rightward space and is used for exhausting;Set below supporting plate
Suspension arrangement is equipped with, for hanging workpiece, heater is additionally provided with lower layer space;The hot blast of extraction enters further into
Recovered energy in lung heat recovery system, the WHRS includes evaporator, and expanding machine, working medium pump, condenser should
WHRS is organic rankine cycle system, and its interior circulation has refrigeration working medium.
Further, for hot blast with row after evaporator heat exchange into air, working medium is changed into high after being absorbed heat in evaporator
Warm gases at high pressure, subsequently into low temperature low pressure gas is become after carrying out expansion work in expansion, carried out in condenser is entered cold
The liquid for low-pressure low-temperature is coagulated, is finally pumped into by working medium pump in evaporator and carries out subsequent cycle.
Particularly, expanding machine is followed by generator, for generating electricity.
Further, the heater is arranged on the centre of multiple workpiece, be fixed on body of heater bottom and supporting plate it
Between.
Particularly, polylith wind deflector is provided with the bottom of body of heater, wind deflector is inclined plane shape, and the inclined-plane is along air-flow
Direction rise.
The present invention uses intermediate heating device so that workpiece can be heated to be more uniformly distributed with heat stepwise, is filled using wind-guiding
Put so that the flowing of hot blast is more smoothly, carries out recuperation of heat to hot blast using organic Rankine bottoming cycle, greatly improves regenerative furnace
Capacity usage ratio.
Brief description of the drawings
When considered in conjunction with the accompanying drawings, can be good at understanding that the structure of the present invention, principle, work are special with reference to following description
Point and advantage, but accompanying drawing described herein as is used for that the present invention is explained further, and accompanying schematic figure is intended merely to preferably right
The present invention illustrates, and does not form improper restriction to the present invention, wherein:
Fig. 1 is the structural representation of the supplementary heating type tempering furnace of the present invention;
Fig. 2 is the system schematic of the waste heat recovery plant in Fig. 1.
Embodiment
With reference to example and accompanying drawing, the invention will be further described, it is noted that following examples are only
To be schematical, it is not intended to the limitation present invention.
With reference to figure 1, supplementary heating type tempering furnace of the invention includes body of heater 1, and support is disposed with the inner horizontal of body of heater 1
Plate 5, supporting plate 5 are tightly connected with the front and back walls inside body of heater 1, so as to which body of heater 1 is separated into upper sheaf space 11 and lower layer space
12, all there is certain distance between supporting plate 5 and two side walls of body of heater 1.Upper sheaf space includes dividing plate 6, and the one of dividing plate 6
End is sealed against on supporting plate, and the other end is sealed against in the inner top wall and front and back walls of body of heater 1, so that will be upper
Sheaf space is separated into leftward space and rightward space.
Sidewall horizontal extension of the supporting plate 5 from dividing plate 6 to body of heater, and certain distance is kept between the inwall of body of heater,
So as to limit wind inlet channel 112 between leftward space and lower layer space 12.And blower fan 7 is provided with rightward space and is used for
Exhausting.
The lower section of supporting plate 5 is provided with suspension arrangement, for hanging workpiece 4, the bottom of body of heater 1 is provided with polylith and led
Aerofoil 8, wind deflector 8 is inclined plane shape, and direction of the inclined-plane along air-flow raises.
Thus, when hot blast impacts the bottom of tempering furnace 1, due to the presence of wind deflector, air-flow will rise, and impact workpiece
4, workpiece is heated.
Hot blast generating means 2 are configured in the leftward space of upper sheaf space 11.
Heater 3 is additionally provided with lower layer space, heater 3 is arranged on the centre of multiple workpiece 4, is fixed on stove
Between the bottom of body 1 and supporting plate 5.Thus, hot blast is sent out from hot blast generating means 2, by air channel 112 on the left of lower layer space
Workpiece heated, then by heater 3 carry out warming temperature after, continue the work in the rightward space to lower layer space
Part is heated, and then the air channel between dividing plate and tempering furnace is extracted out by blower fan 7.
The hot blast of extraction is entered further into lung heat recovery system 9 and recovered energy.
The WHRS includes evaporator 91, expanding machine 92, working medium pump 93, condenser 94, the Waste Heat Recovery system
Unite has refrigeration working medium, hot blast to be arranged after being exchanged heat with evaporator 91 into air for organic rankine cycle system, its interior circulation.Working medium exists
It is changed into high temperature and high pressure gas after being absorbed heat in evaporator 91, it is low subsequently into low temperature is become after progress expansion work in expansion 92
Calm the anger body, in condenser 94 is entered be condensed into the liquid of low-pressure low-temperature, evaporator 91 is finally pumped into by working medium pump 93
Middle carry out subsequent cycle.
Expanding machine is followed by generator 95, for generating electricity.
Present invention employs the reason of intermediate heating device so that workpiece can be heated to be more uniformly distributed with heat stepwise, uses
Organic Rankine bottoming cycle carries out recuperation of heat to hot blast, greatly improves the capacity usage ratio of regenerative furnace.
Although be described in detail to the present invention in conjunction with the embodiments, it should be understood by those skilled in the art that
Ground is that the present invention is not limited only to specific embodiment, on the contrary, in the various amendments without departing from the application spirit and essence, is become
Shape and replacement are all fallen among the protection domain of the application.
