Description
Technical field
The utility model belongs to reclaimer field, relates to nitrocotton, especially a kind of for nitrocotton smoke of gunpowder recovery system.
Background technology
Along with the development of science and technology, the range of application of nitrocotton is no longer confined on war products, but is embodied in the every aspect of daily life, such as Automobile paint, solid alcohol and electronic product binding agent etc.Nitrocotton needs carry out in separation and boiling water and slough wherein excessive spent acid in nitrated rear needs respectively, wherein and operation normally main wash in pot the nitrocotton after depickling is carried out boiled in and, wash and neutralization reaction owing to relating to boiling simultaneously, period has a large amount of smoke of gunpowder and produces, so need to reclaim in time, usually be all adopt common acid fog recovery device to collect, but because on nitrocotton production line, nitric acid dosage is large, even after neutralization, its smoke of gunpowder heat is still very high and growing amount is larger, it has 2 problems: 1, smoke of gunpowder temperature is high, itself and water generate the course of reaction of nitric acid originally as exothermic reaction, not only cause the low potential safety hazard certain in addition of reaction efficiency, 2, after reclaiming, the concentration of nitric acid is wayward, usually also needs following process to reuse, cause the energy, artificial on waste.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide that a kind of structure is simple, reasonable in design, highly effective and safe for nitrocotton smoke of gunpowder recovery system.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of for nitrocotton smoke of gunpowder recovery system, comprise smoke of gunpowder discharge line and retracting device on production line, retracting device comprises three packed towers, three high-pressure pumps, spray-water source and nitric acid collector, the arrangement of three packed tower orders, spray-water source is connected with first packed tower top water inlet by a high-pressure pump, first packed tower bottom delivery port is connected with second packed tower top inlet by another high-pressure pump, second packed tower bottom delivery port is connected with the 3rd packed tower top inlet by remaining high-pressure pump, 3rd packed tower bottom delivery port is communicated with nitric acid collector, on production line, smoke of gunpowder discharge line is connected by appendix with the smoke of gunpowder import of the 3rd packed tower bottom, the smoke of gunpowder outlet of the 3rd packed tower bottom connects the smoke of gunpowder import of second packed tower bottom by appendix, the smoke of gunpowder outlet of second packed tower bottom connects the smoke of gunpowder import of first packed tower bottom by appendix.
And be communicated with a cyclone separator on nitric acid collector, this cyclone separator discharge end is communicated with product collector.
Advantage of the present utility model and good effect are:
The smoke of gunpowder recovery system that the utility model provides is based on three packed towers, for the situation that smoke of gunpowder amount is larger, the smoke of gunpowder is by the pipe design of scientific order, the smoke of gunpowder is made fully to meet Water Sproading, cyclone separator has also been installed additional in recovery end, remove foam in the nitric acid obtained after packed tower reclaims, further ensure the mass fraction of the nitric acid of reusable edible.
Accompanying drawing explanation
Fig. 1 is syndeton schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of for nitrocotton smoke of gunpowder recovery system, comprise smoke of gunpowder discharge line 4 and retracting device on production line, retracting device comprises three packed towers 6, three high-pressure pumps 8, spray-water source 9 and nitric acid collector 3, the arrangement of three packed tower orders, spray-water source adopts water-supply-pipe 7 to be communicated with by a high-pressure pump with first packed tower top water inlet, first packed tower bottom delivery port adopts water-supply-pipe to be communicated with by another high-pressure pump with second packed tower top inlet, second packed tower bottom delivery port adopts water-supply-pipe to be communicated with by remaining high-pressure pump with the 3rd packed tower top inlet, 3rd packed tower bottom delivery port adopts water-supply-pipe to be communicated with nitric acid collector, on production line, smoke of gunpowder discharge line is connected by appendix 5 with the smoke of gunpowder import of the 3rd packed tower bottom, the smoke of gunpowder outlet of the 3rd packed tower bottom connects the smoke of gunpowder import of second packed tower bottom by appendix, the smoke of gunpowder outlet of second packed tower bottom connects the smoke of gunpowder import of first packed tower bottom by appendix.
All be provided with regularly arranged filler in each packed tower, for heat radiation, each packed tower top is all provided with shower nozzle, and this shower nozzle is communicated with packed tower top water inlet.The smoke of gunpowder floats, and Water spray backward under flow through filler and the smoke of gunpowder reacts, the second packed tower and the 3rd packed tower are continued to flow in reacted nitric acid whereabouts, then enter nitric acid collector.
Nitric acid collector connects cyclone separator 2, and nitric acid is separated by this cyclone separator further, is separated foam, and foam fraction factor thing is discharged (mainly air bubble and carbon dioxide), and the nitric acid after separation squeezes into product collector 1.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
