Description
Technical field
The present invention relates to a kind of apparatus and method for reclaiming sulfur.
Background technology
As it is shown in figure 1, sulfur recovery unit of the prior art include that main chamber 2 ' and main chamber 2 ' be joined directly together useless
Heat boiler 3 ' is connected with steam heater 4 ' by the steam heater 4 ' that main pipeline 1 ' is connected with waste heat boiler 3 '
One-level claus reaction device 5 ', the side of main chamber 2 ' is provided with air intlet 21 ', connects and has for main chamber 2 '
The blower fan of interior conveying air, the port of export at waste heat boiler 3 ' has molten sulfur pond 6 ', at steam heater 4 ' also by pipeline connection
Entrance point be provided with middle pressure steam import 41 ' and condensate outlet 42 '.
The sulfur recovery technology of said apparatus is: by process gas, (its composition is mainly composed of CO2、H2S、CH3OH、N2And H2
Deng) be passed in the middle of main chamber 2 ', the temperature in combustor controls between 850 DEG C～1200 DEG C, hydrogen sulfide containing technique
Gas and air or oxygen-enriched air or pure oxygen mixed combustion, a part of hydrogen sulfide and oxygen reacts generation sulfur dioxide, its remaining part
Dividing hydrogen sulfide and sulfur dioxide to react and generate gaseous elemental sulfur, in main chamber 2 ', the main reaction occurred is as follows: H2S
+O2=SO2+H2O, H2S+O2=S+H2O, H2S+SO2=S+H2O；Enter directly into from main chamber 2 ' gas out
Carrying out cooling down in waste heat boiler 3 ' and reclaim heat energy, the temperature in waste heat boiler 3 ' is normally controlled in 135 DEG C to 155 DEG C
Between, it is cooled into molten sulfur at main chamber 2 ' reacted gaseous mixture gas through gaseous elemental sulfur therein of lowering the temperature and separates,
The molten sulfur obtained is by discharge of pipes to molten sulfur pond 6 ', and other compositions in gas keep gaseous state and are passed into steam heater 4 '
In, utilize high-temperature steam that gas is heated, by control steam be passed through speed and heating and temperature control is existed by intake
Between 210 DEG C to 230 DEG C, after high-temperature gas is heated to the temperature requirement of one-level Crouse's import, gas is passed into one-level gram labor
This reactor 5 ' reacts.
The sulfur recovery rate of this sulfur recovery technology reaches 99.5%, and product purity reaches more than 99.95%, and Exhaust Emission Control is always
Sulfur <below 100ppm, but the resistance utilizing this device to easily cause sulfur recovery system during carrying out sulfur recovery raises,
Cannot smoothly complete the recovery operation to sulfur, reason includes following several respects: be on the one hand: because traditional handicraft uses process gas
(it is mainly composed of CO, H with fuel gas2、CO2And N2Deng) mode burnt altogether carries out, add through steam heater 4 '
Gas after heat is passed directly to reaction in the middle of one-level claus reaction device 5 ', causes due to the formation of fuel gas incomplete combustion
White carbon black can be brought in claus reaction device, add the stove brick of main chamber 2 ' and brickwork joint by the powder of heat-barrier material with gas
Body enters in claus reaction device together, causes reactor bed dust stratification, and then causes bed resistance to raise, and then causes whole
Resistance in individual sulfur recovery system raises, and the pressure of fan outlet is normally controlled in about 23kpa, when in sulfur recovery system
When resistance is more than 23kpa, air cannot be sent in the middle of main chamber 2 ' by blower fan smoothly, causes amount of oxygen in main chamber 2 '
Deficiency, and oxygen deficiency to cause the reaction of the sulfur recovery in combustor to carry out thorough, also result in fuel gas incomplete combustion,
Reduce sulphur recovery efficiency, even result in the reaction in main chamber 2 ' time serious and interrupt, and then cause cannot completing sulfur is returned
Receive；
Still further aspect is: because sulfur recovery system add vapours and fuel gas is not the most that sulfur recovery unit provides, once outside
Boundary cannot provide when adding vapours and fuel gas, and sulfur recovery is stopped in emergency, and sulfur recovery system cannot be replaced with the displacement gas of heat,
Now contain the process gas reduction along with temperature of gaseous elemental sulfur, react the gaseous elemental sulfur of generation in the reactor in one-level gram
The catalyst surface condensation of Louth reactor 5 ' becomes solid-state, and catalyst surface once has ash, will form ash sulfur, ash sulfur
Fusion temperature is more than 450 DEG C, and when sulfur recovery system is again started up, reaction bed temperature is the highest only 300 DEG C, ash sulfur without
Method melts gasification, causes the bed heap dust stratification sulfur of one-level claus reaction device 5 ', causes sulfur recovery system resistance to raise, and just
Normal solid sulfur will become molten sulfur at 150 DEG C and start gasification.
When one-level claus reaction device 5 ' bed dust stratification or ash sulfur time cause SR to raise time, whole system be required for by
Urgent interruption clears up dust stratification with ash sulfur to eliminate resistance, but after clearing up dust stratification and the grey sulfur of bed, dust stratification and ash sulfur meeting. every time
Constantly accumulation, at most can only maintain 2-3 month, and SR can raise again, then need again to interrupt the work of whole device,
Bed to claus reaction device carries out clearing up dust stratification and ash sulfur again, thus causes the work efficiency of sulfur recovery lowly, cost liter
Height, is unfavorable for that produce is normally carried out.
