Description
Technical field
The invention belongs to sulfur recovery technology and environment protection field, it is related to vapour oxid-reclamatiom technique sour in coking, petrochemical industry
The device of the molten sulfur pond sulfur vapor recycling used, the molten sulfur pond composite cover of specially a kind of Recovered sulphur steam.
Background technique
China's coking, petrochemical industry will contain sour vapour using oxid-reclamatiom technique generally using claus oven or sulphur furnace processed
Sulfuric acid vapour is converted into sulphur simple substance and is recycled.The liquid sulphur simple substance of generation is drained in molten sulfur pond and keeps in, and molten sulfur pond temperature is general
It is 135 ~ 155 DEG C, at a temperature of this, Molten sulphur in molten sulfur pond is added due to sulphur, Sublimated Sulphur and the heat preservation steam in steam
The sulphur steam evaporated when hot, diffuses in working environment, since temperature reduction causes sulphur to crystallize rapidly, is easy in molten sulfur pond
More than liquid level, on chamber wall, in Chi Gai, especially working environment, sulphur condensation phenomenon is serious, causes to deposit everywhere in workplace
In sulphur solid, there is stronger corrosiveness to equipment and pipeline, former pond lid exhausting pipeline etc. is also frequently occluded.Sulphur in air
Sulphur is more more serious to the respiratory tract harm of worker, and a large amount of sulphur steam release can also cause ambient enviroment centainly to pollute.
So existing acid vapour is using in oxid-reclamatiom technique, molten sulfur Chi Chikou is covered usually using muti-piece cement cover board
Lid, since sulphur simple substance easily distils under liquid condition and expand calculations, cement cover board can only play blocking and spread and insulation effect, due to
Sealing effect is poor, and a large amount of sulfur vapor diffusions, have an adverse effect: 1. pairs of surrounding metal reactors and pipeline cause to corrode；2.
It causes damages to operator's respiratory system；3. blow-down pipe results in blockage；4. sulphur simple substance yield causes damages.In summary it asks
Topic, removes the sulphur in the working environment, becomes the environmental issue for needing to solve.
Summary of the invention
The present invention is intended to provide a kind of molten sulfur pond composite cover for removing sulphur steam, can effectively solve sulphur by condensing recovery
Steam is from molten sulfur pond top diffusion problem, to effectively solve the adverse effect generated in the prior art.
The present invention is achieved by the following technical scheme:
A kind of molten sulfur pond composite cover of Recovered sulphur steam, including compound lid, the composite cover body are interior fixed equipped with chilling roller rotation
Position frame, installs the chilling roller that a row can rotate on the chilling roller rotary positioning frame, the one end of each chilling roller is fixedly connected with one
Gear is rotated, the rotation gear of all chilling roller ends is rotated by chilling roller to be connected after drive chain connects with chilling roller rotation drive device
It connects；It is located at each chilling roller side on the chilling roller rotary positioning frame and is equipped with bite；Each chilling roller one end enters equipped with cooling medium
Mouth hose, the other end are equipped with cooling medium outlet hose, between the cooling medium inlet hose and cooling medium outlet hose
By being located at the heat-exchanging spiral-coil contacted in chilling roller and with chilling roller inner wall connection；The cooling medium inlet hose of each chilling roller converges
After collection and cooling medium upper hose A and low pressure steam pipe C are met, after the cooling medium outlet hose of each chilling roller collects and connects cooling
Medium outlet pipe B and steam condensate (SC) pipe D.
The principle that molten sulfur pond composite cover removes sulphur steam is the sulfur vapor from molten sulfur pond, and it is multiple to rise to molten sulfur pond
When closing lid, sulfur vapor in temperature lower than the chilling roller surface condensation condensation for leading to cooling medium in sulphur fusing point, through after a period of time
Condensation, chilling roller surface can condense one layer of crystalline solid sulphur.When chilling roller is by the timing driving rotation of chilling roller rotation drive device, condensation
The simple substance sulphur on chilling roller surface is set in the case where being cut under bite acts on, falls back to molten sulfur surface under gravity.
The sulphur concentration for diffusing to molten sulfur pool surface is effectively reduced in this kind of equipment, and by sulphur recovery therein, and effectively improves sulphur
Output capacity.
Have that chilling roller is multiple in composite cover body, each chilling roller is respectively equipped with cooling medium and steam inlet and outlet.Under normal circumstances
It is passed through cooling medium in chilling roller, when occurring condensing under the abnormal conditions that sulphur can not be cut in chilling roller, changes logical low-pressure steam and carries out
Melt the sulphur for being condensed in chilling roller surface.
The present invention solves the problems, such as that the sulphur partial vapour pressure in existing Claus method molten sulfur pond is excessively high, and it is stifled to solve elemental sulfur
The problem for filling in pipeline etc., solves molten sulfur pond workplace sulphur condensation problem, solves as caused by sulphur devaporation
Sulphur loses problem, solves the problem of environmental pollution as caused by sulphur steam.
The present invention has rational design, has good practical application and promotional value.
