Abstract
A kind of ammoniacal liquor for composite heat transfer is online compounding system continuously, enter the automatic flow control system that liquefied ammonia pipeline before liquid blender and water pipeline are made up of flowmeter and flow control valve respectively, liquefied ammonia mixes in static mixer with water, there is water-cooling jacket outside static mixer, prepared qualified ammoniacal liquor and left the ammonia neutralization system use that ammoniacal liquor hybrid system supplies composite heat transfer process continuously.Ammoniacal liquor can be prepared continuously, the ammonia temperature of preparation, at about 35 DEG C, does not have vaporizer phenomenon, safe and reliable, ammoniacal liquor is with preparing with use, have mixing velocity fast, the feature that automatic control level is high, eliminates tank used for storing ammonia, eliminate circulating pump, floor space is little, and number of devices is few, saves equipment investment.
Description
Technical field
Chemical technology field, specifically a kind of ammoniacal liquor of composite heat transfer process is prepared continuously, is supplied technology continuously.
Background technology
In order to sufficient reacting in compound phosphatic fertilizer production process, need to use excessive acid, but excessive acid is present in composite fertilizer can make fertilizer acidity strengthen, direct use can injure crops, so neutralizing acid excessive in fertilizer is a necessary process, with in ammonia and excessive acid be composite heat transfer common method, but when using pure liquefied ammonia and solid material to react, because liquefied ammonia is volatile substances, evaporation rate is fast, some ammonia is not able to do in time just to have vapored away with acid reaction, both raw material was wasted, pollute environment again, liquefied ammonia outlet is embedded in below the material of needs neutralization by some technique, still the volatilization of ammonia can not be avoided, both resource was wasted, contaminated environment again.Use in the ammonia neutralization composite fertilizer containing some water excessive sour time, ammoniacal liquor can spread in solid material, and ammonia and acid are fully reacted, and the volatilization effectively reducing ammonia is wasted.
Existing ammoniacal liquor preparation technique is generally batch formulation in the container that volume is larger, and often prepare a collection of with a period of time, preparation speed is slow, and take up room large, equipment investment is high.
Because the process for preparation of liquefied ammonia and water is a strong exothermic process, for preventing liquid gasification, some technology have installed radiator coil tube in a reservoir, cause equipment volume huge.
Submitted to by Anhui Ya Lande new energy materials limited company, the application of application number 201220289666.x " ammoniacal liquor compounding system ", its shortcoming is that system unit is many, and volume is comparatively large, and ammoniacal liquor preparation speed is slow.
Equally open by Guizhou " a kind of ammonia preparation device being exclusively used in washing sulfuric acid tail gas " that phosphorus (group) Co., Ltd submits to, there is the huge and ammoniacal liquor of complex structure system too and prepare slow-footed problem.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of take static mixer as the technical scheme of hydrid component.Water-cooling jacket is had outside static mixer, the automatic flow control system be made up of flowmeter and flow control valve installed respectively by the liquefied ammonia pipeline entered before liquid blender and water pipeline, these two flow control systems control to enter the liquefied ammonia flow of liquid blender and the flow of water, the proportioning of strict guarantee liquefied ammonia and water respectively.Liquefied ammonia mixes in static mixer with water, and the heat that mixed process produces is taken away by the water-cooling jacket outside static mixer, thus keeps ammonia and water mixed process not generating gasification.Prepare qualified ammoniacal liquor and leave the ammonia neutralization system use that ammoniacal liquor hybrid system supplies composite heat transfer process continuously, start this system and should be specifically noted that safety, needed first to pass into cooling water to water-cooling jacket before passing into liquefied ammonia and water to static mixer, ammoniacal liquor continuous process for preparation middle outlet temperature should control below 35 DEG C.Adjust the flow of liquefied ammonia flow and water according to technological requirement, variable concentrations can be obtained, mix continuous print ammonia spirit.
Invention achieves and use number of devices few than conventional art, structure is simple, eliminates circulating pump, saves power, eliminate large-scale storage tank, take up room little object, have that equipment volume is little, mixing Quick uniform, heat exchange in time, the feature of safety and on-line continuous operation.
Accompanying drawing explanation
Fig. 1 is flow chart of the present invention.
Detailed description of the invention
Implementing used unit of the present invention is all common original paper and equipment on chemical plant installations, a flowmeter 1, b flowmeter 3 can select mass flowmenter, a control valve 2, b control valve 4 can select the common control valve of chemical industry, static mixer 6 adopts rotary vane type static mixer, cooling jacket 5 outside static mixer can be welded on static mixer when processing static mixer, and the connection between equipment all adopts chemical industry common pipe, pipe fitting and valve.
Embodiment
The present embodiment used unit is all common original paper and equipment on chemical plant installations, mass flowmenter selected by a flowmeter 1, b flowmeter 3, a control valve 2, b control valve 4 can select common control valve, static mixer 6 adopts rotary vane type static mixer, cooling jacket 5 outside static mixer is welded on static mixer when processing static mixer, and the connection between equipment all adopts chemical industry common pipe, pipe fitting, valve.Through on probation, this system directly can be linked into the neutralized system of composite heat transfer, can prepare ammoniacal liquor continuously, stability of flow, the ammonia temperature of preparation, at about 35 DEG C, does not have vaporizer phenomenon, safe and reliable, ammoniacal liquor with use, has mixing velocity fast with preparation, the feature that automatic control level is high, compared with conventional art, eliminates tank used for storing ammonia, eliminate circulating pump, floor space is little, and number of devices is few, saves equipment investment.
Claims (2)
1. for an ammoniacal liquor continuously online compounding system for composite heat transfer, it is characterized in that entering on the liquefied ammonia pipeline before liquid blender and on water pipeline respectively by the automatic flow control system be made up of flowmeter and flow control valve; Liquefied ammonia mixes in static mixer with water; Water-cooling jacket is had outside static mixer; Qualified mixing ammoniacal liquor leaves the neutralized system use that ammoniacal liquor hybrid system supplies composite heat transfer process continuously.
