Description
Technical field
The utility model relates to industrial furnace technology field more particularly to a kind of triple Waste Heat Recovery systems of step-by-step movement push rod furnace
System.
Background technique
Push rod furnace is one kind of industrial furnace, is mainly used for the heating of the metals embryo material such as copper ingot.Current main heating method
It is to be heated the air in burner hearth, the exhaust gas after heating is discharged into outdoor using electrical heating elements or natural gas.These
Exhaust gas temperature is very high, has very high thermal energy, and directly externally discharge will cause very big energy waste, wait to recycle.
Utility model content
The purpose of the utility model is to overcome the deficiency in above-mentioned background technique, a kind of the triple of step-by-step movement push rod furnace are provided
Waste Heat Recovery System can recycle the heat of exhaust gas, energy saving, reduce entreprise cost.
The technical purpose of the utility model is achieved in that
A kind of triple Waste Heat Recovery System of step-by-step movement push rod furnace, it is characterised in that: including exhaust emission pipe and fresh air
Preheating pipe；Exhaust gas air-suction duct is equipped with heat exchanger and exhaust fan, and the internal channel lower end of heat exchanger passes through pipeline and furnace
The connection of thorax leading portion, internal channel upper end are connected by the entrance of pipeline and exhaust fan, the outlet of exhaust fan by exhaust piping with into
Expect the rear end connection of room, the front end of feed space is equipped with exhaust pipe；The entrance of fresh air preheating pipeline and the outer of heat exchanger lead to
The connection of road upper end, the outer tunnel lower end of heat exchanger is continuously connected to the back segment of burner hearth, fresh air pipeline and day by fresh air pipeline
After right feed channel connection, burner hearth back segment is connected by pipeline.
Preferably, the entrance of the fresh air preheating pipeline is connect by fresh air branch pipe with fresh air pipeline, on fresh air branch pipe
Equipped with valve.
Preferably, the exhaust piping is equipped with valve.
The utility model has the beneficial effect that the utility model using the heat preheating embryo material of exhaust gas and combustion-supporting sky
Gas improves furnace charge and air themperature, reduces energy consumption, and energy-saving and emission-reduction reduce entreprise cost.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model.
Fig. 2 is the left view structural representation of the utility model.
Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, triple Waste Heat Recovery System of a kind of step-by-step movement push rod furnace described in the utility model, including
Exhaust emission pipe and fresh air preheating pipeline.
The exhaust gas air-suction duct is equipped with heat exchanger 5 and exhaust fan 7, and the internal channel lower end of heat exchanger passes through pipeline
It is connected to the leading portion of burner hearth 1, internal channel upper end is connected by the entrance of pipeline and exhaust fan, and the outlet of exhaust fan passes through flue gas leading
Road 8 connect (front end inlet 4 of the rear end docking burner hearth 1 of feed space) with the rear end of feed space 10, and the front end of feed space is equipped with useless
Gas delivery pipe 11 and removable cover 12 (reducing the amount that exhaust gas when feeding enters workshop).
The entrance 13 of the fresh air preheating pipeline is connect with the outer tunnel upper end of heat exchanger, under the outer tunnel of heat exchanger
End is connected after fresh air pipeline is connected to natural gas line 2 by pipeline by the back segment that fresh air pipeline 3 is continuously connected to burner hearth
The back segment of burner hearth.
The entrance of the fresh air preheating pipeline is connect by fresh air branch pipe 6 with fresh air pipeline, and fresh air branch pipe is equipped with valve
9.Valve 9 also is provided on the exhaust piping.
The working principle of the utility model is: under normal circumstances, the temperature of burner hearth is segmented gradually rises from front to back, this reality
After novel exhaust fan work, the high-temp waste gas of burner hearth back segment and not combustion-supporting air flow forward, when by burner hearth leading portion
Preheating has just enter into the furnace charge of burner hearth, this is one to preheat again；One again preheat after exhaust gas temperature reduce, enter hot friendship from burner hearth front end
The internal channel of parallel operation, the cold air entered in heat exchanger with outside carry out heat exchange, cold air are preheated, this is double pre-
Heat；From heat exchanger come out cold air, after exhaust fan enter exhaust piping, be sent into feed space, preheat feed space in newly into
Room temperature furnace charge, this is triple preheatings.In above process, after exhaust fan work, the exhaust gas and air of burner hearth back segment are pumped,
Burner hearth back segment is filled up after outdoor cold air and natural gas mixing.Above-mentioned cold air enters pre- after the outer tunnel of heat exchanger
Heat is flowed by fresh air pipeline, and the natural gas being sent into natural gas line mixes, and mixed gas temperature at this time is also mentioned
Height, can more rapidly, full combustion, improve efficiency of combustion.When mixed gas temperature is excessively high, when fire box temperature is excessively high, fresh air branch
Valve on pipe controls aperture, supplements not preheated cold air, reduces the temperature of mixed gas, as supplementary means, work as furnace
When bore temperature is excessively high, the valve opening of exhaust piping is adjusted, can control the mass rate of emission of exhaust gas, adjusts the temperature in burner hearth.
The above is only the preferred embodiment of the present invention, and for those skilled in the art, this is practical new
Type can have various modifications and variations.Within the spirit and principle of the utility model, it is made it is any modification, equally replace
It changes, improve, should be included within the scope of protection of this utility model.
