The function of incinerator is to compile the furnace gas that has volatile solvent of discharging from oven, makes volatile solvent in row's burning and reclaim heat before atmosphere by means of the heat of incinerator.After the oven furnace gas that contains volatile solvent enters incinerator, heated for 1 second at least being not less than under 750 ℃ of furnace temperature, volatile solvent is thoroughly incinerated, finish, burn the EGT of discharging the back and be higher than 750 ℃ the volatility treatment of waste gas.This part heat can be recycled, and for oven provides pure high-temperature hot-air, this cover system is referred to as afterburner combustion system, and it comprises incinerator, heat exchanger.
The utility model content
The purpose of this utility model be to provide a kind of make waste gas burning completely, energy saving and environment friendly waste gas combustion furnace.
For achieving the above object, the concrete technical scheme taked of the utility model is as follows:
The horizontal torpedo jar design of the whole employing of incinerator is made up of exhaust gas inlet section, waste gas burning stove section, second-time burning section, heat-recovery section and smoke evacuation system.For providing the burner of heat, incinerator is arranged in the leading section of incinerator; For the abundant burning that guarantees waste gas is provided with waste gas burning stove section, this waste gas burning stove section and exhaust gas inlet section separate by the prefabricated eddy flow tracery wall of refractory material, consider that simultaneously waste gas can impact burner combustion, establishes the burner combustion sleeve; Waste gas through high-temperature ignition after a segment distance carries out abundant mixed combustion; Thorough for guaranteeing burning simultaneously, establish the second-time burning section, establish the refractory material filter in the section, gas is fully mixed through the refractory material filter; Secondly can draw the heat of burning back flue gas in a large number, form high temperature face, be convenient to unburnt waste gas in this section formation second-time burning.
Waste gas is through fully entering heat-recovery section and smoke evacuation system after the burning, this heat-recovery section is established one or more levels heat exchanger, for the color painted steel strip oven provides high-temperature preheated air, therefore, this waste gas combustion furnace is also being undertaken the task that heat is provided for unit except that finishing the burned waste gas task.
Compare with traditional technology, this utility model has following tangible technical characterictic:
(1) the exhaust gas inlet section is established waste gas eddy flow tracery wall, can make waste gas enter the waste gas burning section under the eddy flow state, can realize abundant mixed combustion.
(2) be provided with the second-time burning section, can guarantee that waste gas in this section realization completing combustion, does not have environmental pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is along the profile of A-A line among Fig. 1;
Fig. 3 is along the profile of B-B line among Fig. 1.
The specific embodiment
Consult Fig. 1, be overall structure schematic diagram of the present utility model.As can be seen from the figure, waste gas combustion furnace mainly is made up of exhaust gas inlet section 1, waste gas burning section 2, second-time burning section 3, heat-recovery section and smoke evacuation system 4.Wherein exhaust gas inlet section 1, waste gas burning section 2, second-time burning section 3 adopt the design of torpedo jar, and each section body of heater is made up of refractory material heat insulation layer and outer steel structure.
Exhaust gas inlet section 1 comprises: parts such as exhaust gas entrance adapter 6, end heat supply burner 5, the prefabricated eddy flow tracery wall 7 of refractory material, burner combustion sleeve 13.Its end is seen Fig. 2 to view.Wherein: separate by burner combustion sleeve 13 between exhaust gas entrance adapter 6 and the end heat supply burner 5, become not connected passage.The air flue 7a that exhaust gas entrance is taken on the 6 eddy flow tracery walls of making by refractory material 7 is connected with waste gas burning section 2, and end heat supply burner 5 is connected with waste gas burning section 2 by burner combustion sleeve 13.The end heat supply burner 5 that adopts in the utility model is an existing finished product, therefore this heat supply burner 5 is not further described.
Waste gas burning section 2 is the main burning zone of incinerator, and burnt gas stopped for 1 second at least in this stove section, finishes the mixed combustion of waste gas, is convenient maintenance, and this stove section is established maintenance fire door 12.
The profile of second-time burning section 3 such as Fig. 3 are provided with refractory material filter 8, and filter 8 is a loose structure, and this hole 8a can be square hole, circular hole or seam shape structure, and it is example that this example adopts borehole structure.Filter 8 fire resistant materials of attaching most importance to, thermal capacitance is higher, the high-temp waste gas of waste gas burning section 2 burnings by the porous 8a on this filter 8 after, filter 8 absorbs a large amount of heats, temperature is higher, plays the effect of regnition; Simultaneously, burnt gas disperses fully to mix in filter 8, has therefore realized secondary completing combustion.
