Temperature is too high to cause the situation that rubbish is excessively burned in the first cavity 1 to occur, and the thermal source that should suitably reduce in the first cavity 1 is supplied
Give, this timed unit controls the first blower unit 8, the second blower unit 17, the first magnetic valve 13, the second magnetic valve 14, the
Three magnetic valves 15, electric supply installation, control valve 22 are acted, and the first blower unit 8, the second blower unit 17 are adjusted to stop shape
State, and, the first magnetic valve 13 is adjusted to opening, the second magnetic valve 14 and the 3rd magnetic valve 15 and is adjusted to close shape
State, the tail gas for only being produced using waste incineration in the second cavity 2 is that the position in the first cavity 1 near top carries out heat supply, on
The rubbish that rheme is put can tentatively be removed using the heat in pipeline to the moisture of rubbish, rubbish is kept drying higher
Degree, and, electric supply installation is adjusted to off-position, the heat energy supply in the first cavity 1 is reduced on the basis of energy-conservation, with
And, the aperture of control valve 22 is adjusted to the first aperture, using the high temperature in the second cavity 2 to newly entering into the second cavity 2
Interior rubbish is preheated and dried, and makes the rubbish of new entrance keep drying improving effect of the new rubbish when burning.
The actual burning situation of rubbish in the first cavity 1 is analyzed by detecting the profiling temperatures in the first cavity 1,
Concrete operations are：Detect two temperature values of specified location in the first cavity 1, and calculate the difference of above-mentioned two temperature value, then
Size according to above-mentioned difference judges the different burning feelings of rubbish in the first cavity 1 from the comparative result of the size of preset difference value
Condition；Because waste incineration is located proximate to the bottom of the first cavity 1 in the first cavity 1, and heat transfer mode from bottom to top, because
What the temperature in this first cavity 1 should gradually rise from top to bottom, by comparing two differences of the temperature value of position
Actual profiling temperatures can comprehensively be recognized in the first cavity 1, it is to avoid hold when being analyzed using single temperature value
The drawbacks of easily affected by many factors and restriction, accurately detected with to the actual temperature in the first cavity 1, so as to be control
The actual profiling temperatures of device analysis processed provide solid reference.When comparative result shows actual in the first cavity 1
When temperature is relatively low, should take measures to improve the temperature in the first cavity 1, now not merely with the tail gas of the generation of the second cavity 2
The heat energy for containing, and heated using the gas in the pipeline set in 7 pairs of the first cavitys 1 of heater, with shorter
Time quickly improve the first cavity 1 temperature, while increased using the first blower unit 8 gas in pipelines flowing speed
Degree, makes more gases in the unit interval enter in the pipeline set in the first cavity 1, and it is more hot to be that the first cavity 1 is taken
Energy；When comparative result shows that actual temperature is higher in the first cavity 1, the heat supply in the first cavity 1 should be suitably reduced, this
When not only stop using heater 7 to be heated, and reduce the quantity delivered of the tail gas that the second cavity 2 is produced, to reduce by the
Energy supply in one cavity 1, while stopping using the first blower unit 8 to increase the flowing velocity of gas in pipelines, it is to avoid
First cavity 1 absorbs excessive heat and causes the situation that rubbish is excessively burned in the first cavity 1, it is ensured that rubbish in the first cavity 1
Burning situation be in stabilization state；Further, it is that the energy is circulated to use, by detecting the tail gas of the second cavity 2
Temperature analyze the burning situation of rubbish in the second cavity 2, when the exhaust temperature of the second cavity 2 is higher, then comprehensively using upper
The heat energy contained in tail gas is stated, and the second cavity 2 is fed by charging aperture, make the high heat in the second cavity 2 to more
More untreated rubbish carries out burning disposal, is then the using the second blower unit 17 when the exhaust temperature of the second cavity 2 is relatively low
Two cavitys 2 more oxygen of taking carry out accelerated combustion, so, it is ensured that the temperature of the tail gas that waste incineration is produced in the second cavity 2
Enough for the first cavity 1 carries out heat supply, the first cavity 1 and the He of 2 the first cavity of the coordinated guarantee of work of the second cavity 1 are being realized
The purpose of energy-conserving and environment-protective is realized in second cavity 2 on the basis of waste incineration progress.
