Accompanying drawing explanation
Comprising accompanying drawing is further understand the present invention for providing, and they are included and form a application's part, and accompanying drawing shows embodiments of the invention, and plays the effect explaining the principle of the invention together with this description.In accompanying drawing:
Fig. 1 shows the operating structure schematic diagram of one embodiment of the invention.
Detailed description of the invention
With detailed reference to accompanying drawing, embodiments of the invention are described now.In the case of any possible, in all of the figs the identical mark of use is represented same or analogous part.In addition, although the term used in the present invention selects from public term, but some terms mentioned in description of the present invention may be that applicant selects by his or her judgement, its detailed meanings illustrates in the relevant portion of description herein.In addition, require not only to pass through used actual terms, but the meaning that also will be contained by each term understands the present invention.
Fig. 1 shows the operating structure schematic diagram of one embodiment of the invention.As shown in the figure, a kind of wind-introducing energy-saving device 100 being applicable to burner comprises oxygen level sensor 1, auxiliary air channel 2, needle valve 3 and servo control mechanism 4.Oxygen level sensor 1 is arranged on the tail cigarette discharge place (not shown) of burner.Auxiliary air channel 2 is arranged on the air inlet 5 of burner.The damper 6 of burner is connected with the program controller (not shown) of burner, and the aperture of damper 6 is by the demand modeling of program controller according to burner output.Needle valve 3 is arranged in auxiliary air channel 2.Servo control mechanism 4 comprises control module and driver module.Wherein, control module receives and processes the signal of oxygen level sensor 1, and control driver module drive needle valve 3 work, to regulate the intake in auxiliary air channel 2.
As everyone knows, the fuel combustion in burner needs a certain amount of combustion air.Excessive, too smallly all can strengthen burner heat loss due to exhaust gas, the intake of therefore control and participate in burning is very important.As shown in Figure 1, existing fuel vapor burner is provided with an air inlet 5, damper 6 is associated with fuel control unit with mechanical device, due to the limitation of mechanical device itself, cannot ensure that the air capacity provided is exactly the rational air capacity needed for burning, its result is exactly that the excess air coefficient of burner in using is low to moderate " 1 ", or height is even greater than " 1.9 " to " 1.9 ", thus increases the heat loss due to exhaust gas of burner.
Different from existing fuel vapor burner, in the actual motion of the present embodiment, wind-introducing energy-saving device 100 detects the oxygen content of burner tail cigarette discharge by oxygen level sensor 1, the data message detected is sent to the control module of servo control mechanism 4, the oxygen content of the oxygen content data received and storage is set numeric ratio comparatively by control module, the scope of comparative result W should 0.95 ~ 1.05, when ratio W departs from this scope, control module transmits a signal to driver module, needle valve is driven by driver module, to adjust the intake in auxiliary air channel 2, until ratio W gets back to aforementioned zone of reasonableness again, ensure the optimal operating condition of burner.
Preferably, the air outlet 22 in auxiliary air channel 2 is provided with fixed head 7, to keep the initial intake of burner.So-called initial intake refers to the intake of the burner when not installing wind-introducing energy-saving device 100.As shown in the figure, the air outlet 22 of accessory channel 2 connects the air inlet 5 of burner, and needle valve 3 coordinates damper 6 to form the adjustment of auxiliary air quantity, and damper 6 is coarse adjustment, and needle valve 3 is fine tuning.When initially installing, the position of fixed head 7 is adjustable, and the intake that air inlet 5 is adjusted in the position of fixed head 7 maintains original intake, and plate 7 to be fixed has been debugged rear fixing.The adjustment that the effect of fixed head 7 is actually the intake ensureing accessory channel 2 adjusts based on original intake.
Preferably, needle valve 3 comprises the spool 32 be arranged on valve rod 31, and the axis direction of valve rod 31 is consistent with the air intake direction in auxiliary air channel 2, and spool 32 can move around on valve rod 31.As shown in the figure, the spool 32 presented under motion state can move up and down the intake regulating auxiliary air channel 2.Understandable, when spool 32 runs from position A to position B, then the flow area in auxiliary air channel 2 reduces gradually, the corresponding intake decreasing air inlet 5; When spool runs from position B to position A, then the flow area in auxiliary air channel 2 increases gradually, the corresponding intake adding air inlet 5.By spool 32 moving up and down on valve rod 31, the flow area in the auxiliary air channel 2 of adjustment, and then adjustment intake.More preferably, the cross section of spool 32, in the water-drop-shaped of reversal of the natural order of things, can adjust the flow area in auxiliary air channel 2 more subtly.
Preferably, servo control mechanism also comprises transmission mechanism, and transmission mechanism is connected with driver module and needle valve respectively, and driver module drive transmission device is to control needle valve.As shown in the figure, transmission mechanism 8 is connected with valve rod 31, to be with movable valve plug 32 to move up and down, and the size of the intake of adjustment accessory channel 2.
Preferably, the inwall in auxiliary air channel 2 is provided with boss 21, and boss 21 coordinates with needle valve 3.When spool 32 is near boss 21, then the flow area in auxiliary air channel 2 reduces, corresponding minimizing intake; When spool 32 is upwards away from boss 21, then the flow area in auxiliary air channel 2 increases, and correspondingly adds intake.
A kind of wind-introducing energy-saving device 100 being applicable to burner provided by the invention does not affect the former method of operation of burner, and its installation testing step is as follows:
1, in the appropriate location of tail cigarette discharge place of burner, oxygen level sensor 1 is installed;
2, detect the oxygen content of tail cigarette discharge place in the former running of burner, and make a record;
3, at the fixing auxiliary air channel 2 of the air inlet of burner and servo control mechanism 4 (should be noted sealing);
4, connect oxygen level sensor 1, ensure that signal is correctly delivered to servo control mechanism 4.Understandable, its signal connected mode can be wired mode, also can be wireless mode;
5, be that servo control mechanism is powered by the power consumption parameter needed for servo control mechanism 4;
6, the oxygen content parameter of adjusting default;
7, the position of damper 6 is controlled by former program controller;
8, the aperture of the spool 32 of needle valve is arranged on 50%;
9, start after purging before and after burner afterburner experience and enter accidental conditions;
10, the oxygen content of observation detected by oxygen level sensor:
A, oxygen content can slow mobile fixed head 7 when setting value, until stop mobile when flue gas oxygen content changes;
B, the same when oxygen content is greater than setting value, slow mobile fixed head 7, until stop mobile when flue gas oxygen content drops to setting value;
Whether C, observe spool 32 when oxygen content is less than setting value and up move.As correct movement, and can reach setting value, illustrative system is working properly.Still fail to reach setting value as spool 32 up moves to the limit, then readjust the aperture of fixed head 7.Adjustment is until meet preset requirement repeatedly.
11, fixed head 7 is fixed.
