[specific embodiment]
See also Fig. 1 to shown in Figure 5, embodiments of the invention are described in detail.
As shown in Figure 1, it comprises admission line 1, outlet pipe 2, body of heater 3, described body of heater 3 is cylindric, be divided into two-layer up and down in the described body of heater 3, the upper strata is an exothermic layer 4, lower floor is a heat-sink shell 5, be provided with a heating chamber 6 in the described body of heater 3, and run through described exothermic layer 4, heat-sink shell 5, heating chamber 6 upper ends in the described exothermic layer 4 connect a heater 7, and the some groups of cool side heat pipes cell cubes of outside heating chamber 6, forming by some heat pipes 8 around one deck, heating chamber 6 in the described heat-sink shell 5 has overlapped a gas hood 9, and gas can only overflow from gas hood 9 bottoms, the described gas hood 9 outer some groups of hot side heat cell cubes of also being made up of some heat pipes around one deck 10, described admission line 1 is located at described exothermic layer 4, and described outlet pipe 2 is located at described heat-sink shell 5.Described heat pipe unit body is Cryo Heat Tube heat transfer zone, moderate temperature heat pipe heat transfer zone, high-temperature heat pipe heat transfer zone from outside to inside successively, described Cryo Heat Tube heat transfer zone is a water conservancy project matter heat pipe, described moderate temperature heat pipe heat transfer zone is the mercury working medium heat pipe, and described high-temperature heat pipe heat transfer zone is the potassium working medium heat pipe.Reclaim 997 ℃ of used heat of 497 ℃ of ≈ with the potassium working medium heat pipe, reclaim 640 ℃ of used heat of 274 ℃ of ≈ with the mercury working medium heat pipe, the water working medium heat pipe reclaims 227 ℃ of used heat of 30 ℃ of ≈.Be upper volute formula passage 11 between described cool side heat pipes cell cube 8 and the described admission line 1, be following scroll casing type passage 12 between hot side heat cell cube 10 and the described outlet pipe 2.
The present invention is divided into exothermic layer 4 and heat-sink shell 5 two parts, the cool side heat pipes cell cube 8 preheatings organic exhaust gas to be burned of exothermic layer 4, used heat after 10 of the hot side heat cell cubes of heat-sink shell 5 will be burned absorbs and passes to the cool side heat pipes cell cube 8 of exothermic layer 4, to offer the organic exhaust gas preheating, circular flow so constantly, make organic exhaust gas required burning heating load in burning purification process reduce to minimum, when the organic matter in organic waste gas is burning can the balance extraneous heat that replenishes of the heat that self sends in the spontaneous combustion process, organic exhaust gas burns purification process and will be in: just no longer needing to resupply other heat oneself just can burn purification in stove after removing an initial heat supply, reaches obvious energy-saving effect in the organic exhaust gas improvement.In conjunction with Fig. 2, shown in Figure 3, burning process of the present invention: the organic exhaust gas A of low temperature enters the exothermic layer 4 of body of heater 3 from admission line 1, through upper volute formula passage 11, as Fig. 4, be assigned to each cool side heat pipes cell cube 8 import departments 81 equably, under diaphragm 16 effect organic exhaust gas along the Cryo Heat Tube heat transfer zone in the heat pipe unit body 13 to moderate temperature heat pipe heat transfer zone 14, high-temperature heat pipe heat transfer zone 15, enter the heating chamber 6 at heater 7 places from cold junction face 82, heat up reach burn temperature required.Described Cryo Heat Tube heat transfer zone 13 is water conservancy project matter heat pipe, and described moderate temperature heat pipe heat transfer zone 14 is the mercury working medium heat pipe, and described high-temperature heat pipe heat transfer zone 15 is the potassium working medium heat pipe.Because organic exhaust gas is thorough in order to guarantee that it burns when reaching spontaneous combustion, reach high purifying rate, so certain residence time must be arranged, organic exhaust gas down is passed to the heating chamber 6 that is positioned at heat-sink shell 5, and overflow through gas hood 9 bottoms, at this moment the high-temperature gas after purifying overflows rising from gas hood 9 bottoms, as Fig. 5, be pressed into many group hot side heat cell cube 10 hot side inlet 101, pass through high-temperature heat pipe heat transfer zone 15 again, moderate temperature heat pipe heat transfer zone 14, discharge from hot junction face 102 Cryo Heat Tube heat transfer zone 13 heat absorption backs, and through after spiral case passage 12 converges down, through outlet pipe 2 dischargings.
One, because the coefficient of heat transfer that gas-gas exchanges in heat-exchange apparatus is lower, obtain a large amount of heat energy conversion and must be furnished with big heat exchange area, the present invention is a kind of mode of exchange capability of heat maximum in gas-gas heat pipe single tube unitized exchanger, big as the energy consumption demand, need have the advantage that floor space is little, energy consumption is low in the organic exhaust gas burning abatement equipment of the big air quantity of discharging; Two, the present invention adopts upper and lower two layers upper volute formula passage 11, following scroll casing type passage 12, the preheating low temperature waste gas from admission line 1 enter the polygon circumcircle after absorbing heat to inscribed circle heating chamber 6, burning the back hot gas discharges from following scroll casing type passage 12 after the heat exchange cooling from the inscribed circle outflow of inner chamber again, high-temperature gas is all few in body of heater 3 inner chamber heat loss like this, it is lower that the gas of cooling back discharging and low temperature enter the preheating gas temperature, and all place outside scroll casing type passage 11, down in the scroll casing type passage 12 into and out of, increased the peripheral insulation of body of heater.Three, the present invention adopts the combining structures of organizing the heat pipe unit bodies for large-scale incinerator equipment more, can load and unload combination so that transportation.Four, the heat pipe in the heat pipe unit body of the present invention distributes and all is designed to according to the operating temperature heat pipe of different heat-resisting working medium from high to low, it can both be operated in the optimum humidity province, purify and discharge the back hot gas can be reduced to minimum temperature after each zone is by heat absorption after.Deflector 16 in the heat pipe unit body can make the recuperated gas that enters and flow out be full of whole heat-transfer surface preferably to improve its effective heat exchange area and the coefficient of heat transfer, obtain the exhaust temperature that high heat exchange amount improves the preheating waste gas temperature and reduces Purge gas.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process according to this, i.e. the equivalence of doing according to claim of the present invention and description changes and modification, all should still belong in the scope that the present invention contains.
