Description
Technical field
The utility model relates to a kind of liquefying plant, and especially a kind of carbon dioxide collection is used liquefier.
Background technology
In the Alcohol Production process, there is a large amount of carbon dioxide to discharge, CO2 emission produces serious influence to atmosphere to atmosphere, not only can increase greenhouse effects, has wasted valuable charcoal resource again.Therefore, carbon dioxide recovery is significant for social enviroment protection, not only can not influence economic development to enterprise, and has the effect of increasing income and decreasing expenditure.
The utility model content
The technical assignment of the utility model is to provide a kind of carbon dioxide collection to use liquefier to above-mentioned deficiency of the prior art, and this liquefier not only can be controlled the temperature of liquid carbon dioxide, but also can control the liquid level of liquefied ammonia.
The utility model solves the technical scheme that its technical problem adopted: this carbon dioxide collection is used liquefier; Comprise the filling body, it is characterized in that the steam state carbon dioxide inlet pipe that links to each other with drier is positioned at the top of tank body; The liquid carbon dioxide outlet that links to each other with fluid reservoir is positioned at the below of tank body; The heat-exchange tube that is communicated with steam state carbon dioxide inlet pipe and liquid carbon dioxide outlet is positioned at tank body, and liquefied ammonia import and the outlet of vapour ammonia are connected to the below and the top of tank body, and refrigeration machine connects liquefied ammonia import and the outlet of vapour ammonia outside tank body; In the liquefied ammonia import, be serially connected with the liquefied ammonia control valve; On the liquid carbon dioxide outlet, be provided with temperature sensor, be provided with liquid level sensor on tank body top, described temperature sensor and liquid level sensor are connected the automatically controlled part of liquefied ammonia control valve respectively.
Liquefier is a heat transmission equipment.It is to utilize the vaporization of liquefied ammonia need absorb a large amount of heats, with this cool off in the flowing pipe by the cold material carbon dioxide.On producing, the outlet temperature of the carbon dioxide that often requires to be cooled is stable, and this will realize that still, the liquefied ammonia flow both can influence temperature, also can influence liquid level through control liquefied ammonia flow, and temperature and liquid level have a kind of rough correspondence.
Suppose to have the impurity oil leakage to go into, heat transfer coefficient is fallen suddenly,, will increase heat transfer area greatly in order to take same heat away by cold carbon dioxide pipeline.But when the liquefied ammonia liquid level had been flooded all tubulations of heat exchanger, the increase of heat transfer area reached capacity, if continue to increase the liquefied ammonia amount in the tank body, can't improve heat output.But the continuation of liquefied ammonia liquid level raises, and but possibly bring production accident.This is that ammonia will get into the suction port of compressor because the ammonia of vaporization is to reclaim reusablely, and as if the ammonia gas carrying liquid, drop can damage compressor blade, thereby liquefier tank body top must leave enough vaporization spaces, to guarantee good evaporation conditions.In order to keep enough vaporization spaces, will limit the ammoniacal liquor position and must not be higher than a certain ceiling value.For this reason, on temperature control basis, increase a control system that anti-liquid level transfinites.
The utlity model has following outstanding beneficial effect is: owing to be provided with temperature sensor and liquid level sensor, so this liquefier not only can control the temperature of liquid carbon dioxide, but also can control the liquid level of liquefied ammonia.Both guarantee the collection of carbon dioxide, guaranteed the security of equipment work again.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Description of reference numerals: 1 tank body, 2 heat-exchange tubes, the outlet of 3 vapour ammonia, 4 steam state carbon dioxide inlet pipes, 5 driers, 6 refrigeration machines, 7 liquefied ammonia control valves, 8 liquefied ammonia imports, 9 temperature sensors, 10 liquid level sensors, 11 fluid reservoirs, 12 liquid carbon dioxide outlets.
The specific embodiment
Like Fig. 1; This carbon dioxide collection is used liquefier, comprises irritating body 1, and the steam state carbon dioxide inlet pipe 4 that links to each other with drier 5 is positioned at the top of tank body; The liquid carbon dioxide outlet 12 that links to each other with fluid reservoir 11 is positioned at the below of tank body; Fluid reservoir 11 is deposited liquid carbon dioxide, and drier 5 is connected with upstream equipment, accepts from the carbon dioxide that produces in the sweat.The heat-exchange tube 2 that is communicated with steam state carbon dioxide inlet pipe and liquid carbon dioxide outlet is positioned at tank body, forms the co 2 liquefaction pipeline.Liquefied ammonia import 8 and vapour ammonia outlet 3 are connected to the below and the top of tank body, and refrigeration machine 6 connects liquefied ammonia import 8 and vapour ammonia outlet 3 outside tank body, and refrigeration machine 6 can be realized the recycle of medium ammonia.In the liquefied ammonia import, be serially connected with liquefied ammonia control valve 7, the liquefied ammonia control valve is provided with automatically controlled part and is used to control the liquefied ammonia flow.On liquid carbon dioxide outlet 12, be provided with temperature sensor 9, be provided with liquid level sensor 10 on tank body top, described temperature sensor and liquid level sensor are connected the automatically controlled part of liquefied ammonia control valve respectively.
Under nominal situation, by temperature sensor the liquefied ammonia control valve is controlled, with control liquefied ammonia temperature; And when improper operating mode occurring; The liquid level that causes ammonia reach the highest in limited time; Even it is still higher by the outlet temperature of carbon dioxide; But departing from of temperature this moment becomes secondary cause temporarily, and the unlikely damage of protection ammonia compressor has risen to principal contradiction, so liquid level sensor should replace temperature sensor work (promptly handling the liquefied ammonia control valve).
