Description
Technical field
The present invention relates to recovering ammonia technique fields, and in particular to a kind of ammonia system is released recyclable device, super for ammonia system
Press liquefied ammonia (gas ammonia) recycling released.
Background technique
Ammonia is important industrial chemicals, is widely used.After liquid ammonia and volatile at ammonia, ammonia and air reach certain proportion
It meets open fire and is easy explosion, ammonia can lead to poisoning, and irritant to eye, lung's mucous membrane, skin, serious sucking can cause reflectivity
Breathing stops.
In the production of ammonia, conveying and storage, to prevent operation error, instrument from breaking down etc., to cause superpressure to occur quick-fried
It is fried, it is designed with safety valve on pipeline, container, protects the safe operation of equipment, pipeline, when system pressure is more than specified value,
Safety valve is opened, and a part of liquefied ammonia (gas ammonia) is discharged into atmosphere by skirt, pressure is made not exceed permission pressure.Discharge of safety valve
When, ammonia passes through safety valve fairlead direct emission, it is possible to damage and pollute the environment to the person.
Summary of the invention
A kind of ammonia system provided by the invention is released recyclable device, is passed through to collect and is discharged when processing ammonia system safety valve pressure release
Ammonia eliminates the ammonia released to the injury of the person and to the pollution of environment.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of ammonia system is released recyclable device, packet
Recovery tower, its underpart connection emptying general pipeline are included, which is additionally provided with circulating pump, the liquid-phase outlet and import of circulating pump and recovery tower
Connection.
Further, it is additionally provided with pressure transmitter on the emptying general pipeline, is connect with circulating pump.
Further, it is also connected with moisturizing pipeline on the pipeline between the liquid-phase outlet and circulating pump of the recovery tower, mended
Moisturizing regulating valve is installed on waterpipe.
Further, solution is also connected on the pipeline between the circulating pump and the fluid inlet of recovery tower send pipe outside
Road, solution, which is sent outside, to be equipped with solution and sends valve outside on pipeline.
Further, breather valve is additionally provided at the top of recovery tower.
Further, the liquid-phase outlet of the recovery tower is located at recovery tower lower part, and fluid inlet is located at the top of recovery tower,
Pipeline at fluid inlet extends to recovery tower inner hub location, and is equipped with downward spray head in the end of the pipeline.
The recovery tower is cylindrical tower body, is made of from top to bottom spray section, air inlet section, liquid storing section, wherein spray section
Dress rule packing layer.
The present invention is vented general pipeline and recovery tower phase by the way that ammonia system each unit safety valve fairlead is connected to emptying general pipeline
Even, ammonia is directly entered recovery tower and is absorbed using water, the system that circulating pump can promote ammonia and liquefied ammonia.In addition, this Shen
Pressure transmitter please be set, convenient for being pressed in monitoring emptying general pipeline, and by pressure transmitter and circulating pump interlocking of signals, realized automatic
Control.Pipeline is sent outside by setting moisturizing pipeline and solution, convenient for supplementing water into recovery tower, and by the higher ammonium hydroxide of concentration
Conveying recycles outward.The present invention can eliminate ammonia system and injure caused by the person and in the ammonia that super-pressure safety valve is released to environment
Caused by pollute, while recovery ammonia being utilized.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention is further illustrated below with reference to examples and drawings, but the scope of protection of present invention is not limited to
In the range of embodiment statement.
The recyclable device as shown in Figure 1, a kind of ammonia system is released, including recovery tower 3, its underpart connection emptying general pipeline 1, the dress
It sets and is additionally provided with circulating pump 5, the liquid-phase outlet and import of circulating pump and recovery tower connect.
Further, it is additionally provided with pressure transmitter 2 on the emptying general pipeline 1, is connect with circulating pump.It is additionally provided with control
Device, pressure transmitter 2, circulating pump and controller connect, and controller is PLC or embedded system or single-chip microcontroller.Such as optional monolithic
The model STC89C52 of machine.It will be understood by those skilled in the art that the electronic components category such as single-chip microcontroller, pressure transmitter, circulating pump
In technology well known to those skilled in the art, the record of this specification, controller and routine are not limited to the selection of their models
The connection of electronic component and control planning belong to the common knowledge of those skilled in the art, repeat no more in the present specification,
Those skilled in the art can select known approaches to install each electronic chip according to on-site actual situations.
Further, it is also connected with moisturizing pipeline 6 on the pipeline between the liquid-phase outlet and circulating pump of the recovery tower, mended
Moisturizing regulating valve is installed on waterpipe.
Further, solution is also connected on the pipeline between the circulating pump and the fluid inlet of recovery tower send pipeline outside
7, solution, which is sent outside, to be equipped with solution and sends valve outside on pipeline.
Further, breather valve 4 is additionally provided at the top of recovery tower.
Further, the liquid-phase outlet of the recovery tower is located at recovery tower lower part, and fluid inlet is located at the top of recovery tower,
Pipeline at fluid inlet extends to recovery tower inner hub location, and is equipped with downward spray head in the end of the pipeline.It is described
Recovery tower is cylindrical tower body, is made of from top to bottom spray section, air inlet section, liquid storing section, wherein spray section dress rule packing layer.
When safety valve is opened, the ammonia released enters recovery tower by being vented general pipeline, is vented general pipeline at this time and generates pressure, pressure
When power reaches setting pressure P1, signal is passed to circulating pump by pressure transmitter, circulating pump interlocked startup, and solution circulation is to releasing
Ammonia absorbed, safety valve close after, emptying manifold pressure decline, when pressure be down to setting pressure P2 when, circulating pump stop；
Water absorbing ammonia, which reaches, is delivered to ammonium hydroxide storage tank by sending valve outside after a certain concentration, adds desalination water management recovery tower by water compensating valve
Liquid level.Fire-retardant breather valve is to guarantee recovery tower service pressure.
