Description
Technical field
Patent of the present invention belongs to Closed Circulation in Sugar Production technical field, particularly relates to the cooling means of a kind of sugar refinery sulfur burner sulphur gas.
Background technology
Sulfur dioxide is the important auxiliary agent in Closed Circulation in Sugar Production, is used for juice liming process mainly as fining agent, utilizes SO2With stone
Ash breast reaction generates CaSO3Non-sugar in precipitation adsorption syrup, or utilize SO2Carry out sulphur drift decolouring.
Existing production SO2The method of gas is, sulphur is put into burning in sulfur burner and obtains containing SO2High temperature sulphur gas, through folder
Set water cooling, obtains temperature and meets the sulphur gas of production requirement.Owing to sulphur burns insufficient in sulfur burner, still there is part sulphur
Unburned and become sublimed sulfur, simultaneously have again part sulfur burning to generate SO3Gas, therefore except SO in sulphur gas2Outward, also contain
Have sublimed sulfur and SO3。
Using the existing jacket type type of cooling, the sublimed sulfur in sulphur gas can be condensed in pipeline formation incrustation in cooling procedure,
Impact cooling simultaneously blocks pipeline；SO3Then in cooling procedure, the condensation water in sulphur gas is combined generation sulfuric acid and corrodes pipeline, or
Enter syrup eventually and generate sulfate, in follow-up evaporation produces, form incrustation, affect production process.
Content of the invention
Produce sublimed sulfur cohesion incrustation, sulfur trioxide corruption in the sulphur feed channel that sulfur dioxide process exists in order to solve existing sulfur burner
The problems such as erosion, the present invention provides a kind of direct combination cooling method of sulfur burner high temperature sulphur gas, while reaching cooling sulphur gas, removes
Remove sublimed sulfur therein and sulfur trioxide.
Sugar refinery sulfur burner sulphur gas of the present invention purifies and cooling technology scheme is contacted cooling device by water-bath cooling device (1) and syrup
(2) form, it is characterised in that:
A. sulfur burner sulphur gas to be cooled initially enters water-bath cooling device, is sufficiently mixed with water, sulphur gas is purified and is cooled to
Less than 130 DEG C；
B. sulphur gas enters back into syrup contact cooling device, uses low temperature syrup and sulphur gas to carry out two-phase flow contact cooling, by sulphur
Air cooling is to the temperature requiring.
Described water-bath cooling device by tank (3), air-water separation chamber (4), catch mist filler (5), high temperature sulphur gas air inlet pipe (6),
Water-bath head (9), water-bath cooled exhaust pipe (7), water inlet pipe (8) and drainpipe (10) composition etc., sulphur air cooling step is:
A. sulphur gas to be cooled enters from high temperature sulphur gas air inlet pipe, mixes with the water in tank in water-bath head exit；
B. tank maintains stable water level；
C. the waterline of control tank is more than the outlet of water-bath head, makes sulphur gas mix with water.
D. by air-water separation chamber with catch mist filler and carry out air-water and separate.
The structure of described water-bath head is the version that shower nozzle, jet pipe, intercepter plate, gullet plate etc. have distributing gas.
Described mist filler of catching is the filling-material structure being provided that the flowing gas contact surface of solids, such as corrugated folded plate, ripple net, draws
Western ring, Pall ring, cascade ring etc..
Described syrup contact cooling device is the device that a kind of gas-liquid two-phase contacts mixing in flowing.
During equipment runs, SO3It is constantly dissolved in the tank of water-bath cooling device, work as SO3Be dissolved in the water the dense of the sulfuric acid being formed
When degree reaches 10%～98%, then the water in tank is discharged, again intake.
During industry sulfur burner produces, sulfur burning mainly generates sulfur dioxide, but then can contain sublimed sulfur due to incomplete combustion,
Also have part simultaneously and generate sulfur trioxide.Sublimed sulfur can solidify below 110 DEG C, and sulfur trioxide is highly soluble in water, titanium dioxide
Sulphur is then not readily dissolved in water.According to these characteristics, the present invention, according to water bath dust-removing principle, uses the direct mixed method of gas-liquid, makes liter
China's sulphur condenses in water, and SO3It is then dissolved in the water, reach to purify the purpose of sulphur gas.Water-bath simultaneously can by high temperature sulphur air cooling extremely
About 100 DEG C.
Sulfitation sugar mill is it is generally required to by sulphur air cooling to 60～70 DEG C, it is therefore desirable to cool down the sulphur gas after water-bath further.
In order to avoid the steam condensation in sulphur gas in cooling procedure, thus cause SO2Dissolve and form sulfurous acid, corrosion is produced to pipeline, this
The technical scheme of invention is to use low temperature syrup to contact cooling further.The low temperature syrup being used is that subsequent handling needs sulphur
Smoked syrup, such as the pre-ash mixed juice etc. not heated.
The invention have the advantages that
1. avoid sulphur air cooling process sublimed sulfur to condense blocking pipeline and sulphur gas composition is dissolved into the corrosion to pipeline for the acid；
2. reduce sulfate radical and calcium salt content in juice,liming gained juice；
3. advantageously reduce the formation of evaporation incrustation, etc..
4. different from dividing wall type cooling, gas-liquid direct combination cooling method can use Erosion-Resisting Non-metallic Materials making apparatus, thus
Avoid the corrosion of acid.
