Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Fig. 1 is one-piece construction schematic diagram of the present utility model, the left and right left and right orientation be in Fig. 1 mentioned in the present embodiment.
As Figure 1-3, the utility model provides a kind of double-regenerative heating furnace, comprises body of heater 1, and workpiece is placed in body of heater 1.Some groups of regenerator burners 2 are also provided with in body of heater 1, concrete the present embodiment adopts quantity to be two groups, often organize regenerator burner 2 and comprise two regenerator burners 2, in pairs and on the inwall being arranged on body of heater 1 both sides of symmetry, in use, one of them regenerator burner 2 is for coal gas, preheating of air, and another one regenerator burner 2 is for the discharge of the waste gas after combustion heating.
In the present embodiment, each regenerator burner 2 is all connected with gas line 3 and air line 4, gas line 3 and air line 4 are communicated in gas three-way reversing valve 5 and air three-way diverter valve 6 respectively, the both sides of described gas three-way reversing valve 5 and air three-way diverter valve 6 are equipped with open and-shut mode contrary inlet mouth a and venting port b, namely the inlet mouth a of each reversing valve and venting port b is all in one and opens a state of closing, described inlet mouth a is communicated in intake ducting, and described venting port b is communicated in gas exhaust duct; Concrete, the inlet mouth a of the gas three-way reversing valve 5 of body of heater 1 both sides is all communicated in gas inlet pipeline 7, and the inlet mouth a of air three-way diverter valve is all communicated in air intake pipe 8.
The principle of work of the present embodiment: coal gas flows into gas inlet pipe road 7 and enters gas line 3 by the inlet mouth a of the gas three-way reversing valve 5 of body of heater 1 side, air flows into air intake pipe 8 and enters air line 4 by the inlet mouth a of air three-way diverter valve 6, be delivered to preheating in heat-accumulating burner 2, final mixed firing is heated workpiece, and by body of heater 1, the gas three-way reversing valve 5 of side and the venting port b of air three-way diverter valve 6 discharge from gas exhaust duct the waste gas after heating in addition.In the present embodiment, gas three-way reversing valve 5 and air three-way diverter valve 6 are independent settings, and then when there is certain reversing valve excessive discharge temperature, this reversing valve can be stopped separately, all the other reversing valves work on, the continuous heating work of process furnace can be ensured while reducing furnace pressure, also effectively extend the work-ing life of process furnace.
In the present embodiment, when the gas three-way reversing valve 5 of body of heater 1 side and the inlet mouth a of air three-way diverter valve 6 open, the gas three-way reversing valve 5 of body of heater 1 opposite side and the corresponding unlatching of the venting port b of air three-way diverter valve 6, to complete the process of accumulation of heat heating.
As preferential technical scheme, gas three-way reversing valve 5 and air three-way diverter valve 6 are when commutating, and its inlet mouth a can close or open, and its venting port b is relative to inlet mouth a delayed start-up or closedown, and described delay time is 500 milliseconds.Concrete process is: when commutating, first close gas three-way reversing valve 5 and the inlet mouth a of air the three-way diverter valve 6 and venting port b of right side gas three-way reversing valve 5 and air three-way diverter valve 6 in left side simultaneously, again the inlet mouth a of the gas three-way reversing valve 5 in left side and the venting port b of air three-way diverter valve 6 and right side gas three-way reversing valve 5 and air three-way diverter valve 6 is opened simultaneously after time delay 500 milliseconds, because now corresponding inlet mouth a and venting port b closes, the instantaneous short circuit phenomenon produced when just can avoid commutating, prevent crossed contamination.
In the present embodiment, on the left of described body of heater 1 or the gas line 3 on right side be connected to gas three-way reversing valve 5 by coal gas Common Ducts, air line 4 is connected to air three-way diverter valve 6 by air Common Ducts, and then can realize simultaneously air feed.
In the present embodiment, be provided with heat storage in regenerator burner 2, when coal gas or air enter regenerator burner 2, heat storage is to coal gas or preheating of air; When waste gas discharges regenerator burner 2, heat storage absorbs heat to waste gas, in order to coal gas during commutation next time or preheating of air.
More preferred, hot resistance (not shown) is equipped with between gas three-way reversing valve 5 and gas line 3, between air three-way diverter valve 6 and air line 4, this hot resistance is for measuring the spent air temperture of discharge and temperature signal being passed to control device, control device is according to the temperature signal received, when temperature signal displays temperature is too high, the gas three-way reversing valve 5 that control device control temperature is too high or air three-way diverter valve 6 are closed, and prevent the damage of reversing valve.
Obviously, above-described embodiment of the present utility model is only used to clearly demonstrate the utility model example, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
