Description
Technical field
It the utility model is related to recovering ammonia technique field, and in particular to a kind of ammonia system is released retracting device, for ammonia system
The liquefied ammonia of system overpressure relief（Gas ammonia）Recovery.
Background technology
Ammonia is important industrial chemicals, is widely used.Liquid ammonia and volatile into ammonia, ammonia reaches certain ratio with air
Meet naked light after example easily to explode, ammonia can cause to be poisoned, irritant to eye, lung's mucous membrane, skin, and serious suction can cause anti-
The breathing of penetrating property stops.
It is quick-fried to prevent from operational error, instrument from breaking down etc. causing superpressure to occur in the production of ammonia, conveying and storage
It is fried, it is designed with safety valve on pipeline, container, the safe operation of protection equipment, pipeline, when system pressure exceedes setting,
Safety valve is opened, by a part of liquefied ammonia（Gas ammonia）Air is discharged into by skirt, pressure is not exceeded permission pressure.Discharge of safety valve
When, ammonia is directly discharged by safety valve fairlead, it is possible to the person is damaged and environment is polluted.
The content of the invention
A kind of ammonia system provided by the utility model is released retracting device, when handling ammonia system safety valve pressure release by collecting
The ammonia of discharge, eliminate injury of the ammonia to the person released and the pollution to environment.
In order to solve the above technical problems, technical scheme is used by the utility model：A kind of ammonia system, which is released, reclaims dress
Put, including recovery tower, its underpart connection emptying house steward, the device are additionally provided with the liquid-phase outlet of circulating pump, circulating pump and recovery tower
And import connection.
Further, pressure transmitter is additionally provided with the emptying house steward, it is connected with circulating pump.
Further, moisturizing pipeline is also associated with the pipeline between the liquid-phase outlet and circulating pump of the recovery tower, mended
Moisturizing regulating valve is installed on waterpipe.
Further, it is also associated with solution on the pipeline between the fluid inlet of the circulating pump and recovery tower and sends pipe outside
Road, solution, which is sent outside, to be provided with solution and sends valve outside on pipeline.
Further, breather valve is additionally provided with the top of recovery tower.
Further, the liquid-phase outlet of the recovery tower is located at recovery tower bottom, and fluid inlet is located at the top of recovery tower,
Pipeline at fluid inlet extends to recovery tower inner hub location, and is provided with downward shower nozzle in the end of the pipeline.
The recovery tower is cylindrical tower body, is made up of from top to bottom spray section, air inlet section, liquid storing section, wherein spray section
Dress rule packing layer.
The utility model is vented house steward and recovery tower by the way that ammonia system each unit safety valve fairlead is connected into emptying house steward
It is connected, ammonia is directly entered recovery tower and absorbed using water, and circulating pump can promote the system of ammonia and liquefied ammonia.In addition, this
Application sets pressure transmitter, is easy to press in monitoring emptying house steward, and by pressure transmitter and circulating pump interlocking of signals, realize certainly
Dynamic control.By setting moisturizing pipeline and solution to send pipeline outside, it is easy to supplement water into recovery tower, and by the higher ammonia of concentration
Water outwards conveys recycling.The ammonia system that the utility model can eliminate injured to caused by the person in the ammonia that super-pressure safety valve is released and
Pollution on the environment, while recovery ammonia is utilized.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model, but the scope of the requires of the utility model protection are further illustrated with reference to embodiment and accompanying drawing
It is not limited to the scope of embodiment statement.
The retracting device as shown in figure 1, a kind of ammonia system is released, including recovery tower 3, its underpart connection emptying house steward 1, the dress
Put and be additionally provided with circulating pump 5, circulating pump and the liquid-phase outlet of recovery tower and import connect.
Further, pressure transmitter 2 is additionally provided with the emptying house steward 1, it is connected 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 microcomputer.Such as optional monolithic
The model STC89C52 of machine.It will be understood by those skilled in the art that the electronic component category such as single-chip microcomputer, pressure transmitter, circulating pump
