Description
Technical field
The utility model relates to a kind of physics and the general recovery system of chemical field, particularly relates to a kind of equipment that is used to reclaim an ammonium nitrate raffinate.
Background technology
An ammonium nitrate (NH
4NO
3) English Ammounium Nitrate, abbreviate ammonium nitrate as, be white crystals, molecular weight 80.04.An ammonium nitrate main application is: 1, be mixed and made into composite fertilizer as the independent use of nitrogenous fertilizer or phosphate fertilizer, potash fertilizer and use.2, explosive raw material.3, produce the raw material of anesthesia.Generate liquid prod in an ammonium nitrate building-up process; Be transported to the prilling tower top and spray with molten state from prilling tower top inlet 1 '; Become particle because of crystallization in the process that molten state an ammonium nitrate falls; The ammonium nitrate granule that forms drops on the inner material-gathering device 2 ' of prilling tower, and material-gathering device is a funnel-form, under its outlet an ammonium nitrate belt conveyor 3 ' is installed; Ammonium nitrate granule is dropped on an ammonium nitrate belt conveyor by the material-gathering device outlet, and an ammonium nitrate belt conveyor is packed from the packing shop that aggregate bin outlet 4 ' extends upward to tower.An ammonium nitrate has higher water absorbability, very easily from air, absorbs moisture and deliquescence, particle bond.In this process, because being prone to caking, an ammonium nitrate cause material-gathering device outlet conveying not smooth, make an ammonium nitrate drop in the prilling tower easily, and also can leave over nitric acid on the belt conveyor.For the function smoothly of driving next time; To form ammonium nitrate solution with an ammonium nitrate (comprising the deliquescence ammonium nitrate that scatters in the belt transportation) that circulating water flushing is retained in the prilling tower everywhere during parking; These ammonium nitrate solutions can concentrate on the prilling tower bottom under action of gravity; Be referred to as an ammonium nitrate residual night, the concentration range of an ammonium nitrate raffinate is 10%～20%.Each an ammonium nitrate raffinate that produces is transported away as untimely, along with the amount of raffinate is more and more, and when it highly is higher than conveying an ammonium nitrate belt, can be the dissolving of finished product an ammonium nitrate, consequence is hardly imaginable like this.Secondly, the amount of an ammonium nitrate raffinate is many more, and corresponding humidity is big more in the system, and newly-generated an ammonium nitrate moisture absorption caking influences quality.The purity of an ammonium nitrate raffinate is not high, mainly has the particulate contamination and the dust of raw materials for production in some an ammonium nitrate factories, like the coal slurry particle; These impurity are not as well removing; In the entering system, can make the purity of finished product an ammonium nitrate not high, also can make the ammonium nitrate granule outward appearance not good; Have other color, can occur deceiving " an ammonium nitrate ".Not only more dangerous property is sold in influence.An ammonium nitrate raffinate does not add utilization, is discharged to trench, and the processing parameter that can make discharging is not in normal range, and contaminate environment is wasted resource.
The utility model content
The technical problem that the utility model will solve provides a kind of equipment that reclaims an ammonium nitrate raffinate.An ammonium nitrate raffinate purity that this equipment reclaims is good, can be used for ammonium nitrate production, turns waste into wealth.
The utility model reclaims the equipment of an ammonium nitrate raffinate, comprises an ammonium nitrate prilling tower, vapor jet pump, setting tank and hay tank, and wherein: an ammonium nitrate prilling tower bottom offers the outlet of an ammonium nitrate raffinate; The hay tank inwall is fixedly connected with screen cloth; Screen cloth the angle ranging from greater than 0 degree, less than 90 degree with parallel at the bottom of the hay tank jar or at an angle; An ammonium nitrate raffinate outlet of an ammonium nitrate prilling tower is extracted material inlet through first pipeline with vapor jet pump and is linked to each other; The vapor jet pump material outlet links to each other with the setting tank inlet, and the setting tank outlet links to each other with hay tank through second pipeline, is respectively arranged with first, second valve on first, second pipeline; Wherein the position of hay tank is not higher than setting tank, and setting tank is closed container not.
Use vapor jet pump, following some benefit is arranged: 1, an ammonium nitrate raffinate and steam can exchange certain heat, make an ammonium nitrate raffinate keep certain temperature; Because an ammonium nitrate is prone to crystallization, can prevent ammonium nitrate crystal like this, in addition; An ammonium nitrate raffinate is after process is filtered; Need remove the water in an ammonium nitrate raffinate through pervaporation or other steps, an ammonium nitrate raffinate and steam heat-exchanging heat up, and make things convenient for the carrying out of subsequent step; 2, contain some impurity in an ammonium nitrate raffinate, use other pumps, impurity residual obstruction that causes pump easily in the inner pipeline of pump; And the use vapor jet pump, the extraneous pressure steam that feeds is sprayed at a high speed in the inner mixing section of vapor jet pump by the inner nozzle of vapor jet pump, makes mixing section form negative pressure; Thereby make an ammonium nitrate raffinate be extracted in the mixing section; An ammonium nitrate raffinate mixes at mixing section with uperize, under the drive of uperize, makes impurity also can get into setting tank.When using vapor jet pump, setting tank is closed container not, guarantees that steam can be from the opening discharge of setting tank.
The utility model reclaims the equipment of an ammonium nitrate raffinate, and the position of wherein said hay tank is lower than setting tank.Make that an ammonium nitrate raffinate can flow to hay tank from setting tank more easily through the effect of gravity.
The utility model reclaims the equipment of an ammonium nitrate raffinate, and the material of screen cloth is a stainless steel in the wherein said hay tank.An ammonium nitrate is strong acid weak base salt, is slightly acidic, and the screen cloth of stainless steel can protection against corrosion.
The utility model reclaims the equipment of an ammonium nitrate raffinate, and the aperture of screen cloth is not more than 100 orders in the wherein said hay tank.
The utility model reclaims the equipment of an ammonium nitrate raffinate, and it is characterized in that: said screen cloth is with parallel at the bottom of the hay tank jar.When screen cloth with at the bottom of the hay tank jar when parallel, an ammonium nitrate raffinate can be distributed in screen cloth uniformly and filter everywhere, helps improving filter effect and accelerates filtration velocity.
The use step of the utility model is: 1, close first, second valve and vapor jet pump, the water flushing is cemented in the ammonium nitrate granule in an ammonium nitrate prilling tower, forms an ammonium nitrate raffinate; 2, open first valve and vapor jet pump, by vapor jet pump an ammonium nitrate raffinate is extracted to setting tank and close first valve and vapor jet pump, an ammonium nitrate raffinate natural subsidence 20 minutes in setting tank makes the contamination precipitation of 90-95%; 3, open second valve, flow into hay tank through sedimentary raffinate supernatant from setting tank, close second valve, the raffinate supernatant further filters through the screen cloth in the hay tank, an ammonium nitrate raffinate of the recovery that obtains.
Use the utility model can well recycle an ammonium nitrate raffinate; Foreign matter content is few in this an ammonium nitrate raffinate; Can carry back in the neutralizing well again that neutralizer exports in the ammonium nitrate production system to reuse, increase output, and prevented an ammonium nitrate raffinate contaminate environment through after the evaporation concentration.
Below in conjunction with accompanying drawing the equipment that the utility model reclaims an ammonium nitrate raffinate is described further.
