Description
Technical field
The utility model belongs to sodium peroxydisulfate (salt) preparing technical field, relates in particular to the synthetic liquid deamination of a kind of sodium peroxydisulfate (salt), dewater unit.
Background technology
Take ammonium persulfate and NaOH as primary raw material directly synthetic sodium peroxydisulfate be a kind of effective method of generally acknowledging in current world wide, but when generating target product sodium peroxydisulfate, be no matter under alkaline environment or sour environment, also to produce a large amount of ammonias or/and ammonium ion, it will cause not having the generation of the sodium sulphate (under alkaline environment, its side reaction is more violent) of value in reaction system.Given this, timely and effectively ammonia being separated from reactant liquor and reclaimed is one of key issue of the required solution of sodium peroxydisulfate building-up process.In addition, liquid raw material is brought a large amount of water of system into when synthetic, and also generates certain water in reaction, and makes reactant liquor be in serious undersaturated condition, and for this reason, dehydration, concentration operation become another important topic of this process.
Conventionally adopt at present vacuum evaporation method, to realize the object of deamination and dehydration simultaneously.Yet this evaporation operation not only needs to configure efficient vacuum equipment, increase equipment investment and operating cost.The more important thing is preference temperature and the heating means of seeking to be suitable for this operation, because too high evaporating temperature can cause a large amount of the carrying out of decomposing and accelerating side reaction of persulfuric acid ion in synthetic system.Current industrial general steam jacket heating, 160 ℃ of left and right of vapor (steam) temperature, 40 ℃ ~ 50 ℃ of synthetic liquid evaporating temperatures, such evaporating temperature is to cause synthetic liquid overtemperature to decompose, but synthetic liquid and steam jacket contact site branch local overheating, because synthetic liquid forms by chuck periphery retention layer under the promotion of paddle, higher the closer to jacket temperature, sodium peroxydisulfate overtemperature decomposes inevitable.It is that in still, liquid level progressively reduces along with synthetic liquid deamination, dehydration are carried out that steam jacket heats another disadvantage, and chuck exposes liquid level, because solution splashes to cause seriously, scabs.In addition, steam cost is high, from water treatment, starts desalination, deoxidation to utilizing coal heating to become steam, more than 200 yuan of steam cost per ton, and steam is also easily discharged with condensed water, causes operating cost to increase.Steam jacket heating also usually caused spray cans phenomenon because vacuum system loses efficacy, and not only can waste a large amount of materials, also abnormally dangerous.
Utility model content
The purpose of this utility model is just to provide a kind ofly can effectively avoid in building-up process side reaction to occur and the synthetic liquid deamination of the simple sodium peroxydisulfate of technological process (salt), dewater unit.
The technical scheme that realizes above-mentioned the utility model object is:
A kind of sodium peroxydisulfate (salt) synthesizes liquid deamination, dehydration special purpose device, its structure comprises the supporting reactor that is provided with air-distribution mechanism from material machine and inside that has, the air heater with heating and air blast function, this air heater by pipeline pass into described reactor in air-distribution mechanism connection, the exhaust outlet that is arranged at described reactor upper end is communicated with the absorbing mechanism of containing dilute sulfuric acid mother liquor by ammonia pipeline.
The additional technical feature that wherein forms the synthetic liquid deamination of above-mentioned sodium peroxydisulfate (salt), dehydration special purpose device also comprises:
---described absorbing mechanism is that the circular response tower that is provided with liquid import and export and ammonia inlet port and evacuation port forms;
---described air-distribution mechanism is arranged at forming with the round pie structure that the base plate that is provided with import forms by being uniformly distributed leachy panel of described reactor bottom;
---described air-distribution mechanism is that the leachy ring pipe that evenly arranges being fixed on the sidewall of described reactor bottom forms.
A kind of sodium peroxydisulfate provided by the utility model (salt) synthesizes liquid deamination, dewater unit compared with prior art has the following advantages: owing to being provided with in the reactor of special purpose device for the equally distributed air sparger of hot-air, for hot-air homogeneous heating reactant liquor provides condition, and this device can have been simplified technological process greatly, province is except agitator, vacuum and circulating water cooling system, province is except steam heating jacket and condensation water recovery system, thereby saved investment, main is to have facilitated operation, reduced deamination, dehydrating operation expense.

The specific embodiment
Structure and operation principle that sodium peroxydisulfate the utility model being proposed below in conjunction with accompanying drawing (salt) synthesizes liquid deamination, dewater unit are described in further detail:
The synthetic liquid deamination of sodium peroxydisulfate (salt) that forms the utility model and provide, the structural representation of dewater unit are provided.The structure that forms this device comprises the supporting reactor 3 that is provided with air-distribution mechanism 2 from material machine 1 and inside that has, Blast mechanism 4 and the air heater 5 with heating function, this air heater by pipeline 6 pass into reactor in air-distribution mechanism connection, the exhaust outlet 7 that is arranged at reactor upper end is communicated with the absorbing mechanism 9 of containing dilute sulfuric acid mother liquor by ammonia pipeline 8.
Form in the structure of said apparatus,
---absorbing mechanism 9 forms for being provided with the circular response tower 15 of liquid import and export 10,11 and ammonia inlet port 13 and evacuation port 14;
---air-distribution mechanism can for as shown in Figure 2 be arranged at reactor bottom by being evenly distributed with the panel 17 of pore 16 and being provided with the round pie structure that the base plate 19 of import 18 forms; Also can form for the ring pipe that is evenly provided with pore 16 20 being fixed on the sidewall of reactor bottom as shown in Figure 3;
---the exhaust outlet 7 of reactor upper end is provided with the threeway structure with valve mechanism with the junction of ammonia pipeline 8.
Use said apparatus is realized the synthetic liquid deamination of sodium peroxydisulfate (salt), dewatering process step is:
Air enters in the air heater with heating function and heats after the pressurization of air blast mechanism, the hot-air that is heated to 80 ℃-200 ℃ enters in the air sparger of reactor by pipeline, after distributing, the pore on air sparger evenly contacts with reactant liquor, and heat is passed to rapidly to reactant liquor, make ammonia in reactant liquor and moisture rapid evaporation out.Enter ammonia recovery tower containing the higher gas of ammonia by gas pipeline early stage, and from the Recycling Mother Solution that contains dilute sulfuric acid, absorb and become ammonium sulfate, then emptying, mother liquor enters ammonium persulfate electrolysis system again.Later stage does not process by the direct emptying of three-way valve containing steam and the air of ammonia.
