Description
Technical Field
The utility model relates to a nitrogen preparation system in vanadium-nitrogen alloy production, in particular to an ammonia leakage emergency system in nitrogen preparation, and belongs to the technical field of equipment.
Background
High-purity nitrogen is needed to be used in the production of vanadium-nitrogen alloy, manufacturers with a small scale can configure nitrogen making equipment, currently, adsorption nitrogen making equipment is commonly used, but the oxygen content in the nitrogen obtained by the adsorption nitrogen making equipment cannot meet the requirement, further purification is needed, one of the purification processes adopts ammonia decomposition to decompose ammonia gas into nitrogen gas and hydrogen gas, then the nitrogen gas and the product obtained by the adsorption nitrogen making are mixed and reacted, oxygen in the nitrogen gas is removed, and high-purity nitrogen gas with the requirement of composite purity is obtained, the high-purity nitrogen preparation process currently has mature equipment supply, an ammonia gas interface is connected in the equipment, liquid ammonia is connected to the ammonia gas interface of the equipment from a storage tank, ammonia gas leakage is not considered in the current equipment, harm is caused to the environment and personnel after the liquid ammonia leakage, and explosion accidents can be caused in production enterprises of the vanadium-nitrogen alloy, therefore, the existing nitrogen preparation system has potential safety hazards of ammonia gas leakage, the existing method is to prevent ammonia gas leakage through point inspection in production, but the point inspection cannot cover the ammonia gas leakage for 24 hours, manpower is needed, the reliability of the ammonia gas leakage depends on the responsibility of workers, and how to quickly deal with the ammonia gas leakage is a technical problem to be solved in enterprise production.
Disclosure of Invention
The utility model aims to overcome the risk of ammonia gas leakage existing in the existing nitrogen production and provides an ammonia gas leakage emergency system in nitrogen preparation.
In order to realize the purpose of the utility model, the following technical scheme is adopted: emergency system is revealed to ammonia in nitrogen gas preparation, including the liquid ammonia jar, the export of liquid ammonia jar is connected to on supplying the ammonia pipe through outlet pipe, install first automatically controlled valve on supplying the ammonia pipe, many shower nozzles have been arranged to the top of liquid ammonia jar, shower nozzle water piping connection is on the water supply pipeline, install the second automatically controlled valve on the water supply pipeline, under the normal condition, first automatically controlled valve state is normally open, the second automatically controlled valve state is the normal close, install ammonia detection sensor near liquid ammonia jar top, foretell each automatically controlled valve, ammonia detection sensor all is connected to the controller.
Further, the method comprises the following steps of; the liquid ammonia tank be a plurality of, all install manual valve on the outlet pipeline of each liquid ammonia tank.
Further, the method comprises the following steps of; the liquid ammonia tank is arranged in a pool under the ground, the spray pipes are arranged above the pool and are in multiple parallel channels, and the spray pipes cover the whole pool.
The utility model has the positive and beneficial technical effects that: this device is used on the ammonia supply system in nitrogen gas preparation system, when the ammonia takes place to leak, the ammonia detects sensor can be timely detects, the controller obtains the ammonia and reveals and closes first automatically controlled valve after the signal, open the liquid ammonia jar water spray of second automatically controlled valve to the lower part simultaneously, make the ammonia of revealing combine with water and fall in the pond, thereby can effectually prevent that the ammonia from revealing the emergence of the various accidents that lead to, can also prevent and treat the pollution to the environment that the ammonia of revealing caused, this device is reliable effective through the inspection in the practice, the artifical point inspection has been saved.

Detailed Description
In order to more fully explain the implementation of the present invention, examples of the implementation of the present invention are provided. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.
The utility model is explained in further detail in connection with the accompanying drawings, in which: 1: a liquid ammonia tank; 2: an outlet line; 3: a manual valve; 4: a first electrically controlled valve; 5: an ammonia gas detection sensor; 6: a controller; 7: a second electrically controlled valve; 8: a water supply line; 9: a spray header; 10: a pool; 11: an ammonia supply pipe.
As shown in the attached drawing, the ammonia gas leakage emergency system in nitrogen gas preparation comprises a liquid ammonia tank 1, wherein the liquid ammonia tank is multiple, a manual valve 3 is installed on an outlet pipeline of each liquid ammonia tank, the manual valve 3 is convenient for replacing a single liquid ammonia tank, an outlet of the liquid ammonia tank is connected to an ammonia supply pipe 11 through an outlet pipeline 2, a first electric control valve 4 is installed on the ammonia supply pipe, a plurality of spray water pipes 9 are arranged above the liquid ammonia tank, the spray water pipes are connected to a water supply pipeline 8, a second electric control valve 7 is installed on the water supply pipeline, under normal conditions, the first electric control valve is in a normally open state, the second electric control valve is in a normally closed state, an ammonia gas detection sensor 5 is installed above the position near the liquid ammonia tank, and all the electric control valves and the ammonia gas detection sensor are connected to a controller 6.
In this embodiment, the liquid ammonia tank is located in a water pool 10 under the ground, the spray pipes 9 are arranged above the water pool, the spray pipes are parallel to each other, and the spray pipes cover the whole water pool. The pond firstly can be to the cooling of liquid ammonia jar, secondly in case reveal, spray the aqueous ammonia that forms and can collect in the pond, avoided the pollution to the environment.
The controller 6 of the device can be connected with an alarm, and when ammonia gas leakage occurs, the controller starts the alarm.
After the embodiments of the present invention have been described in detail, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the utility model, and it is intended that all simple modifications, equivalent changes and modifications made to the above embodiments based on the technical spirit of the present invention shall fall within the technical scope of the present invention, and the present invention shall not be limited to the embodiments illustrated in the description.
