Description
Technical field
The present invention relates to a kind of with the heat storage tank more than three around the multislot heat accumulation incinerator that is connected a combustion chamber.
Background technology
Life and produce in the organic solvent of extensive use, at room temperature evaporate into gas easily, thus have another name called volatile organic matter (Volatile Organic Compounds, VOCs), and many VOCs have certain toxicity to human body, must be handled; In addition, show by the air quality monitoring data, the ozone that foul smell such as VOCs and NOx precursor and light reaction are produced has to replace the phenomenon that suspended particulates become the major pollutants that influence air pollution index (PSI), is to be one of present prevention and cure of air pollution emphasis so strengthen control VOCs discharging; Yet, the incineration method is a kind of of VOCs exhaust-gas treatment form, VOCs clearance under proper condition can reach more than 99%, and the product after the burning is generally water, carbon dioxide, nitrogen oxide, oxysulfide etc., so be a kind of method that can effectively handle VOCs and foul smell contained in the waste gas.
Secondly; VOCs can adopt heat accumulation incinerator (Regenerative Thermal Oxi dizer usually; RTO) incinerated; and as shown in Figure 1; common heat accumulation incinerator is two accumulation of heat slot types; it comprises two heat storage tank 11a and 11b, air inlet control appliance 12, combustion chamber 13 and Temperature-controlled appliance 14 at least, and in two heat storage tank 11a, 11b filled stone matter or ceramic heat-storing material, and Temperature-controlled appliance 14 is arranged on burner 141 in the combustion chamber 13.Its operation comprises two steps: step 1 is desire to be handled gas be preheated to uniform temperature by air inlet control appliance 12 importings one heat storage tank 11a, then by entering another heat storage tank 11b behind the flame combustion of combustion chamber 13 again, High Temperature Gas after the burning fails to be convened for lack of a quorum heat storage tank 11b heating, also is that the high temperature of air-flow can shift in the heat-storing material that is stored in heat storage tank 11b; Step 2 is to treat through after the time that sets, 12 of this air inlet control appliances change handles the heat storage tank 11b preheating that gas imports accumulation of heat with desire, behind combustion chamber 13, enter chilled heat storage tank 11a again, the high temperature of air-flow can shift again and be stored among the heat storage tank 11a, thereby finishes cycling hot exchange.
Yet when two accumulation of heat trench incinerators switched in heat storage tank preheating/accumulation of heat, the desire in the preheating heat storage tank was handled gas and can be discharged because of incinerating as yet, therefore had the problem that untreated gas is periodically discharged.And be the problems referred to above that solve two heat storage tank incinerators, also just like Fig. 2, three heat storage tank incinerators shown in Figure 3, it comprises three heat storage tank 21a, 21b, 21c at least, airflow control devices 22, the 23a of double combustion chamber, 23b and Temperature-controlled appliance 24, and in three heat storage tank 21a, 21b, 21c filled stone matter or ceramic heat-storing material, and Temperature-controlled appliance 24 is arranged on burner 241a, 241b in combustion chamber 23a, the 23b; Also promptly two heat storage tank incinerators are set up a heat storage tank and a combustion chamber, and each heat storage tank still comprises a flushing end (purge) except that inlet end and outlet side.
Thus, the operation form of three heat storage tank incinerators comprises six steps:
Step 1: off-gas flows imports preheating by heat storage tank 21a and burns by combustion chamber 23a, flushing air-flow (purge gas) will be gone up the untreated waste gas of a circulation by heat storage tank 21b feeding and incorporate in the air-flow, after together passing through the burning again of combustion chamber 23b, and by heat storage tank 21c derivation purifying gas flow and with thermmal storage;
Step 2: off-gas flows imports preheating by heat storage tank 21a and burns by combustion chamber 23a, close the flushing air-flow of heat storage tank 12b and open outlet valve, make the part purifying gas flow by heat storage tank 21b derivation and with thermmal storage, after the part purifying gas flow then passes through the burning again of combustion chamber 23b, and by heat storage tank 21c derivation and with thermmal storage;
Step 3: off-gas flows imports preheating by heat storage tank 21b, washes air-flow by heat storage tank 21c feeding and by combustion chamber 23b burning, incorporate into again in the off-gas flows, and together by after the burning of combustion chamber 23a, and by heat storage tank 21a derivation purifying gas flow and with thermmal storage;
Step 4: off-gas flows imports preheating by heat storage tank 21b, close the flushing air-flow of heat storage tank 21c and open outlet valve, make the part off-gas flows by combustion chamber 23a burning, again by heat storage tank 21a derivation purifying gas flow and with thermmal storage, the part off-gas flows is then by combustion chamber 23b burning, again by heat storage tank 21c derivation purifying gas flow and with thermmal storage;
Step 5: off-gas flows imports preheating by heat storage tank 21c and burns by combustion chamber 23b, and the flushing air-flow is by heat storage tank 21a feeding and by combustion chamber 23a burning, again by heat storage tank 21b derivation purifying gas flow and with thermmal storage;
Step 6: off-gas flows imports preheating by heat storage tank 21c and burns by combustion chamber 23b, close the flushing air-flow of heat storage tank 21a and open outlet valve, the part purifying gas flow is via heat storage tank 21b derivation and with thermmal storage, the part purifying gas flow then passes through the burning again of combustion chamber 23a, and, finish a circulation then by heat storage tank 21a derivation and with thermmal storage.
In other words, three heat storage tank incinerators are because of many steps that feed the flushing air-flow between accumulation of heat and preheating step, so two heat storage tank incinerators are set up a heat storage tank and a combustion chamber, have the problem that untreated gas is periodically discharged though can solve two heat storage tank incinerators, but the existing design form of three heat storage tank incinerators, be that setting with three heat storage tanks presents an array, and between heat storage tank and heat storage tank, be connected with the combustion chamber, thereby present the state of E font, several combustion chambers also promptly must be set at least, and (number of combustion chambers subtracts one for heat storage tank quantity, three heat storage tanks must be provided with two combustion chambers, five heat storage tanks then must be provided with four combustion chambers ...), because each combustion chamber all has a burner and relevant Temperature-controlled appliance, make device complexity and fuel cost higher, and because of airflow direction and changes in flow rate complexity by each combustion chambers burn, and necessary often switching controls fuel quantity, cause fired state to be difficult to stable control, ignition temperature instability.
