Description
Technical field
The invention belongs to field of chemical equipment, relate to a kind of dissolver, specifically a kind of continuous high-efficient Nacl dissolver and method of operating thereof.
Background technology
Current alkali factory all dissolves so that rough salt amount is added in groove tank the method carrying out stirring, the method this small-sized alkali factory still can, and for large-scale alkali factory, due to huge by the salt water yield, this then needs to prepare a large amount of large-scale dissolved salt grooves or tank, and not only occupation of land is many, cost is high, and salt impurity can amass in bottom land, cause the interior easily salt scale coagulation of groove, thus cause salt dissolving tank to need often cleaning, affect and produce and add the amount of labour to workman; Meanwhile, salt solution ratio cannot carry out strict control, directly impacts the output of alkali and product quality.
Chinese patent CN2580302 discloses " large-sized boiler automatic stirring salt dissolving device " and the patent provides a kind of large-sized boiler automatic stirring salt dissolution equipment, although this equipment can accomplish automatic stirring and quick dissolved salt, but salt dissolution rate does not reach 100% all the time, and the dissolved salt time is longer, often a large amount of water wastes.
Chinese patent CN101703899A discloses " mixing dissolver ", mixing dissolver comprises mixing section, mixing section rear end is connected with lysing segment, and this apparatus structure is reasonable, completes more than two strands media and first carry out premixed in an equipment, then dissolve, favorable working performance, simple to operate, pressure is little, safeguard easily, the feature such as not easily scab; But this mixing dissolver meltage is restricted, and medium amount is large, also can scab; And automatically can not regulate the ratio of medium, be not suitable for a large amount of medium continuity and dissolve.
Summary of the invention
Technical problem to be solved by this invention is, overcome the shortcoming of prior art, a kind of continuous high-efficient Nacl dissolver and method of operating thereof be provided, product of the present invention is cost-saving, reduce take up an area, salt solution without interruption, and salt and water eurythmy, be applicable to each large-scale alkali factory.
In order to solve above technical problem, the invention provides a kind of continuous high-efficient Nacl dissolver, comprise salt feed bin and blending tank, salt bin blanking mouth connects blending tank, also comprise star-like blanking device, screw crusher, salt solution ratio adjusting valve, brine pump, first pipeline dissolvers and second pipe dissolvers, salt bin blanking mouth connects screw crusher import by pipeline, and the pipeline between salt feed bin and screw crusher is provided with star-like blanking device, screw crusher outlet connects the charging aperture of blending tank, the charging aperture of blending tank also connects water inlet pipe simultaneously, water inlet pipe is provided with salt solution ratio adjusting valve, the discharging opening of blending tank is sequentially connected in series the first pipeline dissolvers and second pipe dissolvers, and the connecting pipe between blending tank and the first pipeline dissolvers is provided with brine pump, the discharge nozzle of pipeline dissolvers leads to alkaline workshop.
The technical scheme that the present invention limits further is:
Aforementioned star-like blanking device and salt solution ratio adjusting valve are controlled by pneumatic interlocking, adopt pneumatic flowrate control valve; First pipeline dissolvers and second pipe dissolvers comprise blade, interior pipe, outer tube and transmissometer respectively, outer tube is cylindrical seal barrel structure and vertically arranges, interior pipe vertically extend into outer tube, on the outer wall that blade is welded on interior pipe and within centered by pipe to surrounding scattering device, be provided with transmissometer in outer tube; Blade is the laminated structure of graphite carbon plate, resin blade, glass fibre, carbon fiber or aluminum alloy; Salt solution ratio adjusting valve both sides on water inlet pipe are respectively equipped with a water adjusting valve.
Further,
The present invention also provides a kind of method of operating of continuous high-efficient Nacl dissolver, comprises following concrete steps:
Step one: check whole equipment sealing, guarantee equipment and junction thereof do not have leakage scenarios, close all valves;
Step 2: add appropriate salt material in salt feed bin, open star-like blanking device and screw crusher, carries out preliminary pulverizing to salt material and then enters blending tank, open the water adjusting valve on salt solution ratio adjusting valve and both sides thereof simultaneously, discharge water and enter in blending tank;
Step 3: open brine pump (6), saline mixture is pushed ahead, is sent in the interior pipe of the first pipeline dissolvers (11);
Step 4: aforementioned salt aqueous mixtures flows into outer tube from interior pipe, stir through blade rotation, further dissolving, then second pipe dissolvers (12) is entered through pipeline, carry out more efficiently dissolving, observe dissolving situation by transmissometer simultaneously and adjust salt solution ratio in time by salt solution ratio adjusting valve;
Step 5: the salt solution that the discharge nozzle of second pipe dissolvers flows out is transported to alkaline workshop
The invention has the beneficial effects as follows:
The present invention utilizes star-like blanking device to control salt amount, the ratio of salt and water is interlocked by control valve simultaneously, and when star-like blanking device flow is excessive, the flow signal teletransmission of increasing is to pneumatic control valve, and pneumatic control valve increases open degree, increases the flow of water; When star-like blanking device flow is too small, the flow signal teletransmission of minimizing is to pneumatic control valve, and pneumatic control valve reduces open degree, reduces the flow of water; Thus regulate the amount of salt and water in proportion, accurate control, flexible modulation salt and the object of the ratio of water can be reached, promote to dissolve fully, guarantee product quality;
The present invention not only utilizes screw crusher by broken for caking salt to dissolve, and to change dissolving tank be that pipeline carries out salt dissolving, in pipeline dissolvers, establish blade outside pipe simultaneously, accelerate the dissolving of salt, and look into salt dissolving situation by transmissometer sight, salt solution ratio can be adjusted in time; Salt slurry by managing in pipeline dissolvers, then enters outer tube, enters next pipeline dissolvers, has carried out more efficiently dissolving to salt; And the salt water yield that the duct length of dissolvers can need according to the dissolution velocity of salt and alkaline is determined, convenient with repacking, not only cost-saving, and substantially increase production efficiency.
Apparatus of the present invention in use, are different from traditional salt dissolving tank, and impurity is the long-pending end not easily, and not easily salt scale coagulation in groove, does not need normal cleaning, save the amount of labour of workman; And the large large-scale alkali factory of salt dosage also can avoid arranging huge salt dissolving tank, can realize completely its when not increasing new equipment steady control salt solution than and salt solution without interruption, make production more safe and reliable; Apparatus of the present invention not only there will not be because salt dissolving tank prodelta clay what too much affects salt solution supply, cause stopping production, and supply salt solution for continous-stable and provide guarantee.
