Description
Technical field
The utility model relates to a kind of industrial sulfur burner, especially a kind of environmental protection and energy saving sulfur burner of efficiently refining sugar.
Background technology
Overwhelming majority cane sugar factory is used the sulfurous method sugaring, and sulfur burner is the capital equipment of sulfurous method sugar refining technology clarification workshop section, and the quality of its combination property is directly connected to product quality and product cost.The sulfur burner in present domestic sugar refinery all is to use self-melt liquid sulfur burner so far the seventies basically.This sulfur burner is simple in structure, and is easy to manufacture, easy to operate.Body of heater is a rectangle, in establish tray for combustion.This method is that sheet sulphur is directly added in the molten sulfur pans of steel plate welding, and is liquid by the heat melts one-tenth of burning sulphur, flows into the tray for combustion burning.Because body of heater is the semi-open-type structure, very easily causes SO
2The leakage of gas.In case can not the person of modern times in tens meters around leaking, very big to the healthy harm of post workman.These " local method stove " production stabilities are poor, owing to adopted comparatively simple process units, process equipment is unreasonable, make that the combustion process of sulphur is very unstable, how many gas production is difficult to regulate, and ignition temperature is fluctuated, produce a large amount of sublimed sulfur blocking pipes, so that can't normally move.Problem is more, and startup-shutdown is frequent, not only causes the waste of raw material, and explained hereafter has been caused more adverse effect.Except that above 2, SO
2Gas leak is an insoluble problem, because " local method stove " is difficult in time to shut down and to start, runs under the temporary transient situation of shutting down of next stage technology, and in order to guarantee to resume production at any time, therefore " local method stove " standby that need burn away causes a large amount of SO
2Gas directly is discharged in the air.Surrounding environment bigger harm and pollution have been caused.Because above reason after many " local method stove " combustion sulphur device puts into operation, often do not reach expected effect, and the sublimed sulfur that often produces is very big to the quality influence of sugar products, directly has influence on the grade of sugar products and the health of human body.
Along with development of times, the performance of each link equipment of sugar refinery technology, environmental protection and energy saving aspect are required to improve constantly.The development that the combination property of the current used sulfur burner in sugar refinery has been out of step with the times, the superseded replacement is unavoidable.At present, the sulfur burner that can be used for sugar refining technology also has other two types: totally-enclosed self-burning type, spray combustion formula except the self-melt liquid sulfur burner of above introduction (semiclosed self-burning type).
Totally-enclosed self-burning type
Closed burner hearth (air inlet and fluid injection sulphur hole are arranged) and multistage burner that totally-enclosed self-burning type sulfur burner has adopted refractory material to make.The semiclosed self-burning type of combustion mode is the same, all belongs to surface combustion.Its course of work is as follows: molten sulfur is gone in the burner hearth from fluid injection sulphur orifice flow, with the inhaled air catalytic combustion, because multistage burner has increased burning area and burning time, can make sulphur realize completing combustion in burner surface trickling process.Compare with semiclosed self-burning type sulfur burner, obtained higher combustion intensity, effectively reduced equipment volume, the generation that has also reduced sublimed sulfur may.But because burner control exists suitable hysteresis quality, can't control sulphur gas concentration and tolerance flexibly accurately, therefore can't realize that automaticity has been subjected to suitable restriction according to the corresponding sulphur gas of sugarcane juice flow matches supply.
The spray combustion formula
This combustion mode and semiclosed self-burning type, totally-enclosed self-burning type are different, belong to space combustion.Its course of work is as follows: be blown into a certain proportion of air by high-pressure injection atomizing molten sulfur with blower fan and fully mix the moment after-flame.Can accurately control liquid-gas ratio, obtain higher combustion intensity and burning quality, thereby effectively guarantee to generate concentration, purity and the stability of sulphur gas.Since sulphur abundant completing combustion of moment, the possibility that no sublimed sulfur produces.The generation of having avoided the waste of sulphur to greatest extent and having stopped various uncertain factors.There is not hysteresis quality in burning control, can control the growing amount of sulphur gas flexibly fast, realizes that automaticity is unrestricted according to the corresponding sulphur gas of sugarcane juice flow matches supply.The injecting type sulfur burner is in the extensive and successful application of chemical industry.Such large-size chemical is operation for a long time under stable operating mode with the characteristics of sulfur burner, and run duration does not have the molten sulfur burning not have regular variation.Therefore, requirement is so meticulous aspect burning control.But sugar refinery need just can reach optimized intensity of sulfitation according to the flow matches sulphur tolerance of sugarcane juice, and the sulfur content that could guarantee sugar products is at floor level.Therefore, the burning control structure of sugaring sulfur burner is more many with the combustion control technology complexity of sulfur burner than large-size chemical.
The mode of heating that sulfur melting groove adopted that present sugar industry sulfur burner is used has two kinds, Steam Heating mode and heat-conducting oil heating mode.Sulfur melting groove version generally is designed to square container, and distribution steam or heat-conducting oil heating pipe in the groove, steam or conduction oil are elevated to more than 120 degree pipeline temperature by pipeline, make the sulphur fusing of contact heating tube, reach the purpose of molten sulphur.The essence of these two kinds of mode of heatings is the same, and the heating thermal source of promptly molten sulphur is beyond sulfur melting groove (steam-heated thermal source comes from boiler, and the thermal source of conduction oil is from adding the deep fat device) all, and heating tube is essentially the integral body of a connection.There are several problems such as energy saving is poor, the efficiency of heating surface is low, security reliability difference in such mode of heating.Because the heating thermal source outside sulfur melting groove, has the considerable part heat to cause damage when transmitting, and causes energy-saving effect not good, and it is slow to heat up, molten sulphur speed is lower.Because the heating tube pipeline is essentially the integral body of a connection, in case leaking appears in the pipeline somewhere, whole heating system just is forced to quit work, and the high temperature and high pressure steam in the pipeline and conduction oil might cause security incident to external eruption.As leak part and be positioned at the molten sulfur liquid level when following, repair and more change jobs unusual difficulty.And heat-conducting oil system needs the oil circulation of oil pump pump, in case oil pump damages, whole heating system also will quit work.
