Description
Technical field
The invention belongs to hot-blast stove technical fields, particularly relate to a kind of hot-blast stove furnace core.
Background technique
Hot-blast stove can be divided into direct-type hot-blast stove and indirect hot air stove according to working media situation.Direct-type hot-blast stove is adopted
It is directly burnt with fuel, purified processing forms hot wind, and comes heat drying or baking with material directly contact.This kind of method tool
It is high with hot blast temperature to have the advantages that fuel consumption is greatly reduced, but has because containing dust and other in the flue gas after fuel combustion
Evil gas, drying process when not allowing contaminated for dried material are then helpless.Indirect hot air stove, it is main to be applicable in
Dry materials when dried material does not allow contaminated, such as: milk powder, pharmacy, synthetic resin, fine chemistry industry.It is such to add
Thermal is that steam, conduction oil, flame and high-temperature flue gas heating, flue gas etc. are done carrier, and the heat for passing through diversified forms is handed over
Parallel operation heats air.And when using indirect hot air stove structure, it especially directlys adopt combustion apparatus and generates flame and height
It is often huge because of cold side (air side), hot side (flame and high-temperature flue gas) temperature difference when warm flue gas carries out Hot-blast Heating, processing
It is bad often to generate Metal Material Fatigue crackle caused by thermal stress and thermal expansion difference shortly in hot-blast stove operation to produce
The phenomenon that raw clean hot air is polluted by flue gas, when serious can only shutdown maintenance, and energy consumption is larger.
Summary of the invention
The present invention proposes a kind of hot-blast stove furnace core, solves hot-blast stove operation in the prior art and shortly generates thermal stress
And Metal Material Fatigue crackle caused by thermal expansion difference is to generate the phenomenon that clean hot air is polluted by flue gas, seriously
When can only shutdown maintenance, and the biggish defect of energy consumption.
The technical scheme of the present invention is realized as follows:
A kind of hot-blast stove furnace core, including combustion chamber and heat exchanger, combustion chamber are used for outside furnace body to the burning
The fuel portion of indoor offer fuel and air connects, and the combustion chamber is connected with heat exchanger, and organic waste is provided on combustion chamber
Gas import, combustion chamber include the tubbiness combustion section positioned at front end, and the tail portion of the tubbiness combustion section is connected with a snakelike combustion section,
The snakelike combustion section is connect with heat exchanger, and the end of heat exchanger is provided with exhaust gas outlet, the exhaust gas outlet connection the
The air inlet of one shunt conduit and the second shunt conduit, first shunt conduit is located at the upper of the second shunt conduit air inlet
It is square, it is provided with filter in first shunt conduit, the outlet port of first shunt conduit is provided with hermatic door, described
Second shunt conduit and combustion chamber.
Further, second shunt conduit is connected to snakelike combustion section.
Further, the exhaust gas outlet is located at the part except furnace body equipped with differential expansion absorbing structure, the differential expansion
The wall of absorbing structure one end and furnace body is tightly connected.
Further, air-distribution device is provided in the organic exhaust gas import, the air-distribution device includes one horn-like
Body, several wind-distributing pipes are provided in the flaring of horn-like ontology, and several wind-distributing pipes and horn-like ontology form seedpod of the lotus shape.
Further, check valve is provided in second shunt conduit.
Further, the differential expansion absorbing structure is corrugated tube.
In conclusion keeping away the present invention has the advantages that there is good hot expansibility because of snakelike formula heated face structure
Crackle and leakage are exempted from；Meanwhile realizing that exhaust gas can be passed through in combustion chamber by pipeline shunt again when necessary at exhaust gas outlet,
It carries out reaching energy-efficient effect while full combustion.
