Described kiln body 11 comprises two side kiln walls 111, kiln top 113, thermocouple 115.Described two side kiln wall 111 relative spacing settings.Described kiln top 113 connects described two side kiln walls 111 simultaneously, and described kiln top 113 coordinates described two side kiln walls 111 to surround the described receiving space 10 of described kiln body 11.Described thermocouple 115 correspondences are located in described receiving space 10.
Described tunnel cave 1 also comprises along the spaced ground floor burner 1111 of described side kiln wall 111 short transverse, second layer burner 1113 and the 3rd layer of burner 1115.In concrete embodiment, in described receiving space 10, the product of described kiln car 13 deliveries is arranging respectively ground floor burner quirk 131, second layer burner quirk 133 and the 3rd layer of burner quirk 135 with described ground floor burner 1111, second layer burner 1113 and the 3rd layer of horizontal correspondence position of burner 1115.Meanwhile, empirical tests, when the height of second layer burner quirk 133 is 100-300 millimeter, the thermal current in described kiln body 11 is mixed to get the most abundant.
Referring to Fig. 2, is the side structure schematic diagram of the tunnel cave that provides of Fig. 1.Along direction from bottom to top, described ground floor burner 1111, second layer burner 1113 and the 3rd layer of burner 1115 are located at described side kiln wall 111 in interval respectively, on described two side kiln walls 111, with a layer burner, mutually stagger.In concrete embodiment, the burner quantity of described ground floor burner 1111, second layer burner 1113 and the 3rd layer of burner 1115 comprises a plurality of, and along horizontal direction, a plurality of burners of described ground floor burner 1111 are in same level, and evenly interval arranges.The same along continuous straight runs parallel interval of a plurality of burners of described second layer burner 1113 and described the 3rd layer of burner 1115 evenly arranges.In concrete embodiment, the power of described ground floor burner 1111, second layer burner 1113 and the 3rd layer of burner 1115 reduces successively, be the power that the power of described second layer burner 1113 is less than described ground floor burner 1111, be greater than the power of described the 3rd layer of burner 1115.Empirical tests, described three layers of burner are respectively on the varying cross-section of described kiln body 11, be described a plurality of ground floor burner 1111, a plurality of second layer burner 1113 and a plurality of the 3rd layer of burner 1115 space while shifting to install, the gas in described kiln body 11 mixes more even.
Please, referring again to Fig. 1, described gas pipeline system 15 comprises combustion air main pipeline 151, combustion air branch pipe(tube) 153, YE 155, valve 157 and temperature controller (not shown).Described combustion air branch pipe(tube) 153 one end connect described combustion air main pipeline 151, and the other end connects respectively described ground floor burner 1111, second layer burner 1113 and the 3rd layer of burner 1115.Described valve 157 connects described YE 155, and described YE 155 connects described temperature controller (not shown), and described temperature controller (not shown) connects described thermocouple 115.Described YE 155 and described valve 157 are with being located on described combustion-supporting branch pipe(tube) 153, the described thermocouple 115 induction interior temperature signals of described kiln body 11 also feed back to described temperature controller (not shown), and described temperature controller (not shown) commands described YE 155 to control the duty of described valve 157.In concrete embodiment, when described thermocouple 115 senses that the interior temperature of described kiln body 11 surpasses setting numerical value, feed back the first temperature signal to described temperature controller (not shown), by described temperature controller (not shown), command described YE 155, described YE 155 drives described valve 157 to turn the throughput of described combustion air branch pipe(tube) 153 down according to the corresponding control signal that produces of described the first temperature signal.Otherwise, when described thermocouple 115 senses the interior temperature of described kiln body 11 lower than setting numerical value, feed back the second temperature signal to described temperature controller (not shown), by described temperature controller (not shown), command described YE 155, described YE 155 drives described valve 157 to heighten the throughput of described combustion air branch pipe(tube) 153 according to the corresponding control signal that produces of described the second temperature signal, and accelerated combustion improves temperature.In like manner, described gas pipeline system 15 also comprises gas pipeline certainly, and their element formation and operation principle are similar to above-mentioned combustion air pipeline, at this, do not repeat.Burner 1115 is interior passes in described kiln body 11 after mixing described ground floor burner 1111, second layer burner 1113 and the 3rd layer for described combustion air and described combustion gas.
During work, described kiln car 13 delivery product base substrates are contained in the described receiving space 10 of described kiln body 11, after mixing, ground floor burner 1111, second layer burner 1113 and the 3rd layer of burner 1115 that combustion air and combustion gas enter described power decay by described gas pipeline system 15 enter in described kiln body 11, mist is dispersed to described kiln body 11 by described ground floor burner quirk 131, second layer burner quirk 133 and the 3rd layer of burner quirk 135, and product base substrate is heated.
Compared to prior art, described tunnel cave 1 has following beneficial effect:
At described tunnel cave 1, be provided with three layers of burner, and at product middle part, described second layer burner quirk 133 be set, increased hot gas between central region product and flowed, solution middle part temperature is low, the few and pockety problem of hot gas.
On the other hand, hot flue gas is easily gathered in described kiln body 11 tops, cause the interior smoke distribution of described kiln body 11 top density larger, the utility model arranges described ground floor burner 1111, second layer burner 1113 and the 3rd layer of burner 1115 that power reduces successively, efficiently solves the problem of the gas smoke distribution inequality in described kiln body 11, makes product temperature, the atmosphere in kiln body 11, fired even, thereby shorten product firing time, improve product percent of pass, reduced cost, more saved the energy.
