Summary of the invention
In order to address the above problem, the invention provides a kind of oil pipe decontamination heating and temper dual-purpose stove, improve the utilization ratio of the energy, save the energy, temperature-controlled precision is high, and heating and thermal treatment working efficiency are high, and fuel consumption is low.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of oil pipe decontamination heating and temper dual-purpose stove, comprise body of heater and the furnace lining in body of heater is set, in body of heater, lower end is provided with a removable chassis, both sides at body of heater are provided with tightness system, above each tightness system, insert and in body of heater, be provided with burner, the outside of each burner is all connected with gas line, upper end at each burner is also connected with air line, the outlet position of discharging fume above body of heater is provided with secondary combustion chamber, be connected with smoke discharging pipe in described secondary combustion chamber upper end, smoke discharging pipe is connected with an induced draft fan by fume exhaust system.
Further improvement of the present invention is: fume exhaust system comprises first flue gas recovery system, one end of first flue gas recovery system is connected with smoke discharging pipe, the other end of first flue gas recovery system is connected with smoke secondary recovery system, and the other end of smoke secondary recovery system is connected with spray eliminator.
Further improvement of the present invention is: on body of heater, both sides are inserted and are provided with thermopair.
Further improvement of the present invention is: the both sides at body of heater are provided with ladder.
The invention has the beneficial effects as follows: the present invention is placed on forge piece on chassis, be written in body of heater by chassis, the igniting heats forged of closing the door part, burner connects respectively gas pipeline and air line, the two igniting afterfire of meeting, the thermocouple inserting in body of heater can be measured the temperature in stove accurately, accurately, steel pipe is in the process of processing greasy dirt, furnace temperature reaches 650-670 ℃, grease and dirt be fully burning not, therefore at smoke evacuation outlet position, a secondary combustion chamber is set, secondary combustion chambers temp reaches 900-1000 ℃, oil smoke burns away at this, overwhelming majority combustibles is fully burned, reduce impurity and the obnoxious flavour in flue gas.On secondary combustion chamber smoke-exhaust pipeline, first flue gas recovery system is set, the cold air heating that blower fan is produced becomes hot blast, the utilization ratio of Sweet natural gas when combustion-supporting hot blast has improved burning, smoke secondary recovery system becomes hot water the cool water heating in comb, the water of heating is for domestic water, after twice recovery system, be provided with spray eliminator, impurity in flue, then by induced draft fan, pure low temperature flue gas is discharged in atmosphere, this stove does not need work during as tempering stove when second-heating.
Dual-purpose stove overall performance of the present invention is good, and a stove is dual-purpose, and the thermo-efficiency of stove can reach more than 45%, can meet the requirement of top grade stove, not only environmental protection but also energy-conservation, hot blast is fully used, greasy dirt on pipeline also can fully burn, and this stove is manufactured superior, practical, safe, reliable.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of structure of the present invention.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail, this embodiment, only for explaining the present invention, does not form and limits protection scope of the present invention.
As shown in Figure 1, the present invention is a kind of oil pipe decontamination heating and temper dual-purpose stove, comprise body of heater 1 and the furnace lining 2 in body of heater 1 is set, on described body of heater 1, both sides are inserted and are provided with thermopair 14, temperature in convenient accurately measurement stove, be provided with ladder 15 in the both sides of described body of heater 1, facilitate workman to keep in repair, be provided with a removable chassis 3 in the interior lower end of described body of heater 1, the forge piece of needs processing is placed on chassis 3, be written in stove by chassis 3, close fire door, igniting heated parts, be provided with tightness system 4 in the both sides of described body of heater 1, the sealing effectiveness of body of heater while guaranteeing burning, in order to avoid forge piece is caused to damage, above described each tightness system 4, insert in described body of heater 1 and be provided with burner 5, the outside of described each burner 5 is all connected with gas line 6, upper end at described each burner 5 is also connected with air line 7, be connected with smoke discharging pipe 11 in described body of heater 1 upper end, described smoke discharging pipe 11 is connected with an induced draft fan 10 by fume exhaust system, described fume exhaust system comprises first flue gas recovery system 12, one end of described first flue gas recovery system 12 is connected with described smoke discharging pipe 11, high-temperature flue gas is by first flue gas recovery system 12, by cold air heating, hot blast is convenient to smoke discharging pipe 11 inner bag Sweet natural gas mixed firings, improve the thermo-efficiency of way, described first flue gas recovery system 12, the other end be connected with smoke secondary recovery system 13, the other end of described smoke secondary recovery system 13 is connected with spray eliminator 9, flue gas is passing through smoke secondary recovery system 13, be arranged on comb in smoke secondary recovery system 13 in the cool water heating that flows through, the hot water producing can be used for domestic water, the heat of flue gas is utilized for the second time, the flue gas of having lowered the temperature is again by spray eliminator 9, dust granules in flue gas is combined and is deposited in sump with water, flue gas has obtained final purification, under low-temperature condition, be discharged in atmosphere, flue gas after purification to environment without any pollution, heat energy is fully utilized, make whole equipment not only energy-conservation but also improved work-ing life.Steel pipe is in the process of processing greasy dirt, furnace temperature reaches 650-670 ℃, grease and dirt be fully burning not, at smoke evacuation outlet position, a secondary combustion chamber 8 is set, secondary combustion chamber 8 temperature reach 900-1000 ℃, oil smoke burns away at this, and most combustibles are fully burned, and has reduced impurity and the obnoxious flavour in flue gas.On secondary combustion chamber 8 smoke discharging pipes 11, first flue gas recovery system is set, the utilization ratio of Sweet natural gas when combustion-supporting hot blast has improved burning, after first flue gas recovery system, increase a smoke secondary recovery system, the water of heating is used for to domestic water, spray eliminator 9 is set after smoke secondary recovery system, and the impurity in flue, is then discharged to pure low temperature flue gas in atmosphere by induced draft fan.When as tempering stove, second heating chamber need not work.
