Lime slaking technology comprises WET DIGESTION technology and dry slaking technology.The device that WET DIGESTION prepares lime slurry has several digestion machines such as viscous flow formula, oar slot type and rotary type.Dry slaking is produced powdery Ca (OH)
2General two classes of dividing of method: mechanical stirring digestion, flow perturbation stir digestion.
Wherein rotary type digestion machine preferably resolves the shortcoming of slot type lime slaking machine, the mechanization degree height, and continuous production, but investment is bigger, only suitable larger manufacturing enterprise.Rotary type digestion machine is in operation and also can causes plasma discharge hole plug, filter screen to stop up, clear up the problem of difficulty, major cause is the impurity particle that can not digest that is caused by living burning and burning in the unslaked lime, and these particles that are present in the lime slurry are difficult to clean out by effective means.In order to overcome above-mentioned deficiency, patent " quicklime slaking machine particle sorting apparatus, milk of lime prepare throwing device " (patent No. is 200920210521.4) utilizes worm conveyor as dragveyer, has solved present quicklime slaking device and can't clean out particulate problem in the unslaked lime.Its deficiency is that device still requires lime block to enter to be broken into suitable particle size before the digestion machine earlier, crusher noise, vibration are greatly, and expend the electric energy and the fund that originally needn't spend in a large number, because entering the digestion machine, a large amount of coarse particles unslaked lime cause the device rate of wear fast simultaneously.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of wide-size distribution lime block WET DIGESTION device is provided, comprise feed-pipe, the feed liquor sparger, the network chain machine, the digestion slag extracting machine, filter screen, emulsification pump, wash-water pump, flooding nozzle, it is characterized in that the network chain machine, the digestion slag extracting machine is connected successively with emulsification pump, network chain on the network chain machine moves with certain speed, the feed-pipe of network chain machine top carries lime block to drop on the network chain machine, digestion water in network chain machine top flows out through the feed liquor sparger, lime block is evenly drenched, lime begins to digest disintegration, wash-water pump extracts the digestion slurries in the digestion slag extracting machine, by the flooding nozzle that is arranged in network chain machine end lime block is digested the flushing of part material and formed slurries, flow in the digestion slag extracting machine, have agitating vane in the digestion slag extracting machine, proceed the lime slaking process, emulsification pump extracts qualified slurries pressurization fed downstream equipment in the digestion slag extracting machine, and will be in the positive delivery process than big lime particle fragmentation, the tail pipe of emulsification pump connects filter screen, filter screen filters out floating matter in the lime slurry, prevents that it from entering upstream device.
The mode that the digestion slag extracting machine is discharged lime slurry also has: will digest slag extracting machine and be installed in higher position, lime slurry through filter screen, the direct overflow of upflow tube to upstream device; Perhaps digest slag extracting machine sodalime slurries and enter the lime swirler through filter screen, swirler pump, the lower concentration slurries that the lime swirler produces insert upstream device, and the high density slurry reflux that the lime swirler produces is to digesting slag extracting machine.
The access position and the purposes that enter the outside water inlet of wet type lime block slaking apparatus can have multiple choices:
(1) part of outside water inlet is introduced the network chain machine as wash-down water, and another part is used to drench the digestion water of lime block, and remaining wash-down water obtains by the digestion slurries that wash-water pump extracts in the digestion slag extracting machine.
(2) whole introducing network chain machines of outside water inlet are as wash-down water, and digestion water and remaining wash-down water of being used to drench lime block are to obtain by the digestion slurries that wash-water pump extracts in the digestion slag extracting machine.
(3) the digestion slag extracting machine is directly introduced in outside water inlet, and the digestion water and the wash-down water that are used to drench lime block are to extract the digestion slurries that digest in the slag extracting machine by wash-water pump to obtain.
The present invention can digest the wide-size distribution lime block, and the granular size of lime block is not required substantially, and overall energy consumption is low, adaptability good, reliability is high, long service life, is applicable to multiple chemical industry occasion, is specially adapted to wet fuel gas desulfurizing technology.
