Described incinerator air inlet is also provided with methyl alcohol intermediate storage tank.
Described incinerator air inlet is also provided with aiutage.
The injecting substances of described steam boiler is steam.
The beneficial effects of the utility model: the utility model is measured waste gas by thermal resistance and entered incinerator pipeline mouth temperature, in the time there is tempering, suction line temperature rise, be elevated to the temperature feedback of uniform temperature thermal resistance handle measurement to control valve, control valve is opened steam and is sprayed into the fire extinguishing of lowering the temperature, this device has solved the series of problems causing due to tempering, and the generation of Accident prevention has promoted the stable operation ability of whole incinerator greatly.
Brief description of the drawings
Fig. 1 is process chart of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of incinerator tempering detects and extinguishing device automatically, comprise incinerator 1, diesel fuel tanks 2 is connected with incinerator 1 by diesel pump 15, incinerator 1 is connected with wet steamer 3, wet steamer 3 is connected with economizer 4, economizer 4 outlets are provided with air-introduced machine 5, air-introduced machine 5 is connected with chimney, the salt cellar 6 that dewaters is connected with economizer 4 by boiler feed pump 7, air blast 8 is connected with incinerator 1, described extinguishing device comprises steam boiler 9, steam boiler 9 is connected with incinerator 1 admission line, steam boiler 9 gas outlets are provided with quck-opening valve 10, the injecting substances of steam boiler 9 is steam, be provided with thermal resistance 11 at incinerator 1 air inlet pipe road junction, thermal resistance 11 is used for measuring the temperature of exhaust gas entrance, thermal resistance 11 andlogic control devices 12 connect, logic controller 12 is connected with quck-opening valve 10, incinerator 1 air inlet is also provided with methyl alcohol intermediate storage tank 13 and aiutage 14.
When this device work, thermal resistance 11, by the temperature detection of waste gas in incinerator 1 inlet duct is delivered to logic controller 12 after change is sent, reaches after certain value, and interlocking gives an order to open fast pneumatic cut-out quck-opening valve 10 delivering vapors, eliminates the generation of tempering.
CIU process introduction:
(1) waste gas, after water seal, sprays in stove and directly burns.For ensureing security of system, establish aiutage, in the time of CIU fault, waste gas directly enters the dump of discharge inflator.
(2) auxiliary fuel adopts methanol solution.Methanol solution sprays in stove combustion-supporting through pump, burner in storage tank; When waste gas calorific value is higher, when incinerator bore temperature can reach setting value without auxiliary fuel burning, main burner is flame-out; In the time that waste gas calorific value is lower, main burner regulates auxiliary combustion.
(3) full automatic diesel oil burner, for having all the time ever-burning flame in igniting and maintenance stove, prevents detonation.
(4) incinerator adopts horizontal chamber furnace (oven).Waste gas is in incinerator and combustion air mixed combustion, and outlet temperature is 800 DEG C.Flue gas is time of staying 2S under 800 DEG C of environment, and the organic matter in flue gas is decomposed completely.The micro-negative pressure operation of incinerator.For ensureing abundant burning, it is combustion-supporting that gas flare root is established a wind, and wind supply quantity is according to the oxygen content adjustment of outlet flue gas.
(5) utilize the waste heat in flue gas to produce saturated vapor.Its major parameter of wet steamer: pressure: 0.4Mpa (gauge pressure), saturated-steam temperature: 151 DEG C; Horizontal layout, adopts pan shell type flue tube boiler.Produce steam and draw its use.800 DEG C of waste heat boiler input gas temperatures, after heat exchange, outlet temperature is down to 250 DEG C of left and right.Feedwater is steam condensate (SC), and 90 DEG C of temperature, pump into boiler through boiler feed pump.
(6) for reducing auxiliary fuel consumption, reduce operating cost, be provided with economizer.The steam condensate coming from desalination tank enters economizer, enters boiler again and produce steam after heat exchange, has improved the utilization ratio of heat, and after economizer, flue-gas temperature is reduced to 150 DEG C, and through air-introduced machine, flue gas enters chimney qualified discharge.
(7) for preventing that waste gas from carrying out amount shakiness, cause tempering accident, be provided with thermal resistance at admission line and measure temperature, and added quck-opening valve adjusting device, in the time of tempering, automatically add the steam fire extinguishing of lowering the temperature.
