Step 4: being controlled by adjusting heating fan outlet valve into sulfur furnace air capacity, by adjusting diesel oil pump discharge
Valve is controlled into sulfur furnace diesel oil amount, and the heating rate of sulfur furnace is controlled with air capacity and diesel oil amount；
Sulfur furnace baker rate is as follows:
1, room temperature is to 120 DEG C, 15 DEG C/h of heating rate, and in 120 DEG C of constant temperature 72h；
2,120 DEG C to 250 DEG C, 10 DEG C/h of heating rate, and in 250 DEG C of constant temperature 60h；
3,250 DEG C to 350 DEG C, 10 DEG C/h of heating rate, and in 350 DEG C of constant temperature 10h；
4,350 DEG C to 650 DEG C, 10 DEG C/h of heating rate, and 650 DEG C of constant temperature for 24 hours；
5,650 DEG C to 950 DEG C, 30 DEG C/h of heating rate, and in 950 DEG C of constant temperature 8h；
After 950 DEG C of bakers, sulfur furnace manhole is sealed, cold stoking cooling is carried out to sulfur furnace, sulfur furnace temperature is down to 200 DEG C
When, openable sulfur furnace manhole carries out Temperature fall to sulfur furnace, is down to room temperature；
The 1 sulfur furnace exit gas moisture of detection in every 2 hours before sulfur furnace baker terminates, moisture are baker lower than 2.5%
Qualification terminates baker work.
The present invention has the advantage that
The present invention uses slow, uniform heating method, can make the free water in sulfur furnace, the crystallization water are i.e. remaining to combine
Water slow evaporation is precipitated, and sulfur furnace lining, furnace wall is avoided to generate crack and deformation, guarantees that sulfur furnace safely comes into operation, raising is burnt
The service life of sulphur furnace, the new sulfur furnace suitable for Sulphuric Acid Enterprises installation.
[Detailed description of the invention]
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 be the embodiment of the present invention sulfur furnace furnace drying method based on system schematic.
Fig. 2 is the sulfur furnace oven drying temperature and the curve graph of time of the embodiment of the present invention.
[specific embodiment]
Referring to Fig.1-2, below in conjunction with specific embodiment, the present invention is further illustrated.
Fujian Shen Yuan new material Co., Ltd sulfuric acid apparatus sulfur furnace furnace drying method, the sulfur furnace furnace drying method based on be
System is as shown in Figure 1, in Fig. 1, and 1 is diesel oil slot, and 2 be diesel pump, and 3 be baker blower, and 4 be sulfur furnace；
Sulfur furnace main technologic parameters and characteristic are as follows:
The specific operation method is as follows for sulfur furnace baker:
Step 1: starting heating blower, is sent into air into sulfur furnace sulfur furnace；
Step 2: starting diesel pump, diesel oil is sent into sulfur furnace；
Step 3: starting burner, lights diesel oil, start baker；
Step 4: being controlled by adjusting heating fan outlet valve into sulfur furnace air capacity, by adjusting diesel oil ejiction opening
Valve is controlled into sulfur furnace diesel oil amount, and the heating rate of sulfur furnace is controlled with air capacity and diesel oil amount.
Sulfur furnace baker rate is as follows:
1, the 15 DEG C/h in room temperature → 120 DEG C, in 120 DEG C of constant temperature 72h；
2,120 DEG C → 250 DEG C 10 DEG C/h, in 250 DEG C of constant temperature 60h；
3,250 DEG C → 350 DEG C 10 DEG C/h, in 350 DEG C of constant temperature 10h；
4,350 DEG C → 650 DEG C 10 DEG C/h, 650 DEG C of constant temperature for 24 hours；
5,650 DEG C → 950 DEG C 30 DEG C/h, in 950 DEG C of constant temperature 8h；
6, after 950 DEG C of bakers, sulfur furnace manhole is sealed, cold stoking cooling, general 144h are carried out to sulfur furnace；
When sulfur furnace temperature is down to 200 DEG C, openable sulfur furnace manhole carries out Temperature fall to sulfur furnace, is down to room temperature
General 120h.
The 1 sulfur furnace exit gas moisture of detection in every 2 hours before sulfur furnace baker terminates, moisture are baker lower than 2.5%
Qualification terminates baker work, and sulfur furnace oven drying temperature and the curve graph of time are as shown in Figure 2.
Points for attention:
1. debugging heating blower, main air blower and diesel pump before combustion furnace ignition, debugging diesel oil gun sprayer atomization does not have
It is fitted into combustion furnace after problem.
2. sulfur furnace builds completion and gravity-flow ventilation 15 days or more can baker.
3. before baker, opening the hole 30~40mm of φ not less than 8 in sulfur furnace steel shell upper surface, making water vapour during baker
It is excessive, it should be welded after baker.
4. during baker, sulfur furnace stokehold temperature and the sulfur furnace heater outlet temperature temperature difference are no more than 150 DEG C；If the temperature difference is more than
It 150 DEG C, then should increase into sulfur furnace air quantity.
5. must first blow in machine in sulfur furnace ignition process, then slightly open grease gun igniting.Blowing-out machine after truce Shi Xianting oil gun,
It must not reverse operating.Less cooking fume is allowed to be gathered in system, such as misfire must to blown down in system it is clean again again
Igniting, prevents cooking fume detonation.
6. arranging special messenger to see fire when diesel oil burns in combustion furnace, once fire extinguishes, stops oil gun rapidly, restart a little
Fire.
7. the crystallization water is discharged when temperature reaches 350 DEG C, and temperature reaches when oven drying temperature reaches 100 DEG C or more free water discharges
Remnants combination water is discharged when to 650 DEG C, 120 DEG C, 350 DEG C and 650 DEG C this 3 humidity provinces it is noted that constant temperature.
8. all records will be arranged and be bound into book form after sulfur furnace baker, retain for a long time as archives.
In July, 2017, Fujian Shen Yuan new material Co., Ltd creates 400,000 tons of sulfuric acid apparatus, using the method to sulfur furnace
Baker is carried out, so far sulfur furnace operational excellence, has provided safety guarantee for the operation of sulfuric acid apparatus.
Although specific embodiments of the present invention have been described above, those familiar with the art should be managed
Solution, we are merely exemplary described specific embodiment, rather than for the restriction to the scope of the present invention, it is familiar with this
The technical staff in field should be covered of the invention according to modification and variation equivalent made by spirit of the invention
In scope of the claimed protection.
