Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is specifically described, if Fig. 1 is the structural representation of the pre-heated waste gas combustion furnace of organic exhaust gas described in the utility model, as shown in the figure, the pre-heated waste gas combustion furnace of a kind of organic exhaust gas, comprise insulation shell 6, insulation shell 6 is provided with outlet 5, in insulation shell 6, be installed with cylindrical shape preheat exchanger 1, with cylindrical Burning Room 3, preheat exchanger 1 is enclosed within on Burning Room 3 and with the two ends, left and right of Burning Room 3 and is communicated with respectively, one end of Burning Room 3 is fitted with cone burner 2, the other end is provided with preheated air temperature control electric control valve 4.Wherein, described preheat exchanger 1 is provided with the shell side 7 of turnover low temperature waste gas and the tube side 8 of storage high-temp waste gas; The left end of described Burning Room 3 is communicated with the left end of the shell side 7 of preheat exchanger 1, and the right-hand member of Burning Room 3 is communicated with the left end entrance of the tube side 8 of preheat exchanger 1 by the gap passage between preheat exchanger 1 and Burning Room 3, as shown in Figure 4; The right-hand member of the shell side 7 of described preheat exchanger 1 is connected with the exhaust gas entrance 9 on insulation shell 6, as shown in Figure 3.
The pre-heated waste gas combustion furnace of organic exhaust gas described in the utility model, its detailed description of the invention is:
Body of heater be designed to cylinder mode, be conducive to free wxpansion, Burning Room, preheating heat exchanger and insulation shell are made to three layers of telescoping structure (as Fig. 1): inside is Burning Room, cone burner is housed on Burning Room, the outside preheating heat exchanger that makes a circle that wraps, most external is insulation shell, and so structure has also greatly reduced the floor space of equipment.
Wherein, Burning Room adopts 1Cr23Ni13 heat-resistance stainless steel plate to make, and steel plate thickness is more than or equal to 3mm, can ensure that reach more than 25 years the service life under normal operating conditions.
Preheating heat exchanger and pipeline thereof adopt heat-resisting steel sheet and plate and the heat resisting pipe of 0Cr18Ni9Ti to make, and steel plate thickness is more than or equal to 3mm, and steel pipe thickness is greater than 1mm.Steel pipe one end is fixed, and one end can be free to slide, and ensures the flexible surplus of expanding with heat and contract with cold in situation.
Be provided with preheated air temperature control electric control valve near exhaust ports, act on preheat temperature to waste gas and the exit gas temperature of waste gas combustion furnace and carry out the best adjusting.The heat resisting steel that valve body adopts the trade mark to be equal to or higher than 1Cr20Ni14Si2 is made,
Base of furnace body is 180mm shaped steel, and waste gas combustion furnace one end is fixed on base, can slide in one end, can be because of not expanding with heat and contract with cold producer body deformability or the situation of tearing.
Insulation shell: internal layer high-quality insulation material staggered floor is laid insulation, the outside 0.8mm of employing of heat-insulation layer galvanized steel plain sheet seaming seals.
When waste gas enters incinerator, first enter the shell side (being the part outside the heat-exchange tube in preheat exchanger) of preheating heat exchanger by exhaust gas entrance, high-temperature gas in the heat-exchange tube of cryogenic gas and preheat exchanger carries out heat exchange, be increased to 400-450 ° of C, then enter Burning Room, under the fired state of cone burner, Burning Room remains on 750 ° of C, makes off-gas oxidizing be decomposed into CO
2and H
2o, the high temperature purification gas after decomposition enters the tube side (be heat-exchange tube in) of preheating heat exchanger again, newly sends for heating the low temperature organic exhaust gas coming to, is discharged after being reduced to 500 ° of C left and right by outlet.In stove, when temperature superelevation, preheated air temperature control electric control valve is opened, and allows high-temperature gas directly discharge without preheating heat exchanger, has ensured body of heater safety.
Because preheated air temperature control electric control valve is conventionally in closed condition, so the high-temperature gas after burning can only enter tube side, as shown in Figure 4, high-temperature gas is entered by the left end of Burning Room, after burning, going to Burning Room right-hand member is blocked by electric control valve, can only go to the left side by the gap passage between preheat exchanger and combustion chamber and then enter tube side, high-temperature gas is directly discharged by right side outlet after covering in tube side.In the time that preheat temperature is higher, preheated air temperature control electric control valve is suitably opened, some directly discharges outlet from the air door of preheated air temperature control electric control valve to make gas after combustion chambers burn, and the gas that enters like this tube side reduces, and the temperature of preheated air will reduce.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some variations that wherein some part may be made, within belonging to protection domain of the present utility model.
