Background technology
In industrial processes, phosphoric acid and ammonia outside in ammonia reactor reaction generate MAP (slip), and carry out next step PROCESS FOR TREATMENT of later stage by Cemented filling to II effect heater, but in the process due in phosphoric acid and ammonia outside ammonia reactor due to reaction be not very abundant, understand some and react generation MAP (slip) in the duct, problem brought like this is, fouling can be formed at pipe interior in pipeline long reaction process, cause line clogging, form low yield, What is more causes stopping production, cleaning pipe interior difficulty is larger, cleaning cycle is shorter, production efficiency is lower.
Utility model content
In order to overcome a difficult problem for above-mentioned prior art, the utility model provides the neutralization reaction device that a kind of clearing times reduces, enhances productivity.
In order to achieve the above object, the utility model is realized by following scheme, a kind of neutralization reaction device for aminating reaction, comprise: outer ammonia reactor connects II effect heater, it is characterized in that: described outer ammonia reactor is connected to the charging aperture of neutralization reactor upper end by pipeline, the middle part left surface of described neutralization reactor is provided with overfall, overfall is connected to slip collecting pit by pipeline, the top of described neutralization reactor is provided with bleeding point and is connected to cooling tower by pipeline, described neutralization reactor bottom is provided with discharging opening and is transported in II effect heater by pipeline through feed pump, the bottom of described neutralization reactor is provided with a underflow opening, described charging aperture is that the right and left respectively establishes one, described discharging opening is that the right and left respectively establishes one, described neutralization reactor is Φ 2.2m × 3m cylinder round bottom shape.
The utility model can be found out in sum, be originally between original outer ammonia reactor and II effect heater and directly connect with pipeline, owing to reacting insufficient in phosphoric acid and ammonia outside ammonia reactor, reaction can have been continued in the pipeline transported, form MAP (slip), because reaction can form fouling, blocking pipe, add a neutralization reactor between, play transitional function, shorten reaction in the duct, sufficient reacting phosphoric acid and ammonia is not had in neutralization reactor, to continue reaction until complete, neutralization reactor is provided with two charging apertures and two discharging openings, only use one at ordinary times, until another needs cleaning or when safeguarding, another is as subsequent use, the water vapour that the bleeding point that the top of neutralization reactor is provided with will produce in course of reaction, a small amount of ammonia and fluoride carry out post-processed by Cemented filling to cooling tower, the underflow opening that the bottom of neutralization reactor is provided with is for blowing and deslagging, conveniently the MAP after reacted in neutralization reactor is delivered to II effect heater and carries out later stage concentration, a feed pump is set up between the special discharging opening at neutralization reactor and II effect heater, reacted MAP (slip) flows out by neutralization reactor overfall and flow to slip collecting pit by pipeline, slip collecting pit set up the slip memory capacity that improve in reaction, neutralization reactor is arranged Φ 2.2m × 3m and can meet normal Production requirement, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein: 1, outer ammonia reactor; 2, slip collecting pit; 3, bleeding point; 4, charging aperture; 5, overfall; 6, neutralization reactor; 7, discharging opening; 8, underflow opening; 9, feed pump; 10, II effect heater; 11, cooling tower.
