Description
Technical field
The utility model relates to a kind of preparation facilities of ammoniacal liquor, specifically relates to a kind of automation liquefied ammonia preparation ammoniacal liquor device.
Background technology
In industrial production, often need a large amount of ammoniacal liquor of preparation, and ammonia to be emitted a large amount of heat in water-soluble process.If do not take appropriate cooling measure to handle, will cause the ammoniacal liquor system temperature to raise, after ammonia temperature surpassed 60 ℃, ammonia was easy to volatilization, had strengthened the preparation difficulty of ammoniacal liquor.Especially when configuration high concentration ammoniacal liquor, concentration is high more, the easy more volatilization of ammonia, and the preparation difficulty is bigger.Therefore, in joining the ammonia process, need the ammoniacal liquor cooling that circulates.Be the temperature that reduces the ammoniacal liquor system by cooling on the one hand; Be to strengthen circulation to guarantee mixing of ammoniacal liquor on the other hand, accelerate configuration speed.
The preparation of ammoniacal liquor at present generally all is to adopt liquefied ammonia to prepare, and the existing device that uses liquefied ammonia to prepare ammoniacal liquor substantially all exists danger when operation, if very easily there is security incident hidden danger in misoperation.The ammonia concn of preparing change greatly, be difficult for grasping its concentration, be prone to the situation of density unevenness, the production of influence back workshop section.In addition, the device of existing preparation liquefied ammonia inhomogeneous cooling to ammoniacal liquor when preparation is even, cooling velocity and poor effect, lead the volatilization that forms a large amount of ammonias easily, cause a large amount of ammonia losses, cause the wasting of resources, a large amount of ammonia emissions can cause environmental pollution in air simultaneously, influences people's health.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of automation liquefied ammonia preparation ammoniacal liquor device is provided, this preparation ammoniacal liquor device has reasonable in design, the processing safety height, ammonia concn is even, and the loss of ammonia is less, has fewer environmental impacts, can move the production efficiency advantages of higher continuously.
The technical scheme that the utility model solves existing preparation ammoniacal liquor device is: automation liquefied ammonia preparation ammoniacal liquor device, comprise that one can be vaporized into liquefied ammonia the vaporizer of ammonia, vaporizer one end is connected with the liquid ammonia storage tank that liquefied ammonia is housed, and the vaporizer other end is connected with the preparing tank of band cooling coil; Described preparing tank is provided with liquid densimeter, liquid level gauge, thermometer, pure water carrier pipe, cooling water carrier pipe, be provided with ammonia internally piloted valve and ammonia flow meter between vaporizer and the preparing tank successively, the liquid level densitometer connects the ammonia internally piloted valve and controls the conveying capacity of ammonia; The pure water carrier pipe is provided with pure water flowmeter and pure water internally piloted valve, and liquid level gauge connects the pure water internally piloted valve and controls the conveying capacity of pure water; Cooling coil in cooling water carrier pipe and the preparing tank is connected, and the cooling water carrier pipe is provided with the cooling water internally piloted valve, and thermometer connection cooling water internally piloted valve is also controlled the temperature of the conveying capacity of cooling water with constant preparing tank.Adopt this device preparation ammoniacal liquor, whole process for preparation adopts the form of automation control entirely, and the ammonia concn of its preparation is accurate, and concentration is difficult for changing, and the cooling effect to ammoniacal liquor is good in process for preparation, makes ammonia not volatile, and the ammonia loss is little.
The operating principle of automation liquefied ammonia preparation ammoniacal liquor device is: after the preparing tank liquid level drops to a certain degree, liquid level gauge control pure water internally piloted valve send pure water in preparing tank, the pure water feed flow accurately measures by the pure water flowmeter, liquefied ammonia is converted into ammonia from liquid ammonia storage tank through the vaporizer vaporization, ammonia send ammonia to preparing tank by liquid densimeter control ammonia internally piloted valve, and the ammoniacal liquor conveying capacity is accurately calculated by the ammonia flow meter; Simultaneously, in process for preparation, send the cooling coil of cooling water in the preparing tank, the temperature of coming constant preparing tank ammoniacal liquor with the discharge of control cooling coil by thermometer control cooling water internally piloted valve.
In sum, automation liquefied ammonia preparation ammoniacal liquor device of the present utility model adopts the form of automation control entirely in the process of preparation ammoniacal liquor, its preparation back ammonia concn is accurate, concentration is difficult for changing, and the cooling effect to ammoniacal liquor is good in process for preparation, make ammonia not volatile, the ammonia loss is little, has guaranteed the concentration height of ammoniacal liquor; It has reasonable in design, the processing safety height, and ammonia concn is even, and the loss of ammonia is less, has fewer environmental impacts, and can move continuously, and the production efficiency height is saved advantages such as artificial.
