Abstract
The utility model discloses an evaporimeter liquid ammonia recovery system, it is including setting up inside the evaporimeter, being used for carrying out abstergent shower head to the liquid ammonia in the evaporimeter, be located the shower head under, collection liquid funnel and the ammonia absorption cell of setting by the evaporimeter is connected with the liquid ammonia heat exchange tube, the ammonia absorption cell passes through back the liquid pipe and is connected with the liquid ammonia admission pipe, the liquid ammonia admission pipe is provided with the valve with time liquid guan shangjun. Through combining collection liquid funnel in can be with spun solution drainage to liquid ammonia heat exchange tube at the inside shower head that sets up of evaporimeter, wash the liquid ammonia heat exchange tube, the solution after washing pass through back liquid pipe entering ammonia absorption cell, and the realization is to the recovery of liquid ammonia.
Description
Technical field
The utility model relates to a kind of retracting device, is specifically related to a kind of evaporimeter liquefied ammonia recovery system.
Background technology
Liquefied ammonia is also called anhydrous ammonia, is a kind of colourless liquid, has intense stimulus smell.Ammonia is as a kind of important industrial chemicals, for transport and storage facility, usually the ammonia of gaseous state is obtained liquid ammonia by pressurizeing or cooling, but need liquefied ammonia to be reduced into gaseous state in use, normal employing evaporimeter is vaporized to liquefied ammonia, after evaporimeter uses, its inside can remain a small amount of liquefied ammonia, ammonia highly volatile, after placing a period of time, ammonia in evaporimeter can evaporate in air, and human body easily occurs ammonia poisoning phenomenon after sucking, and such as performance has rhinitis, pharyngitis, tracheitis, bronchitis.Patient has pharynx cusalgia, cough, expectoration or spitting of blood, uncomfortable in chest and retrosternal pain etc.
Utility model content
For above-mentioned deficiency of the prior art, the utility model provides evaporimeter liquefied ammonia recovery system can to reclaim a small amount of ammonia residual in evaporimeter, occurs intoxicating phenomenon after sucking to avoid human body.
In order to reach foregoing invention object, the technical solution adopted in the utility model is:
A kind of evaporimeter liquefied ammonia recovery system is provided, it comprises and is arranged on evaporimeter inside, spray head for washing the liquefied ammonia in evaporimeter, is positioned at the liquid collecting funnel be connected immediately below spray head, with liquefied ammonia heat exchanger tube and the ammonia absorption cell being arranged on evaporimeter side; Ammonia absorption cell enters pipe by liquid back pipe and liquefied ammonia and is connected; Liquefied ammonia enters on pipe and liquid back pipe and is provided with valve.
The beneficial effects of the utility model are: can be drained in liquefied ammonia heat exchanger tube by the solution of ejection by the spray head arranged in evaporimeter inside in conjunction with liquid collecting funnel, liquefied ammonia heat exchanger tube is rinsed, solution after flushing enters ammonia absorption cell by liquid back pipe, realizes the recovery to liquefied ammonia.
Accompanying drawing explanation
Fig. 1 is evaporimeter liquefied ammonia recovery system structural representation.
Wherein, 1, ammonia absorption cell; 2, liquid back pipe; 3, liquefied ammonia enters pipe; 4, cover body; 5, liquid collecting funnel; 6, spray head; 7, ammonia vapour-discharge tube; 8, valve; 9, blast pipe; 10, air blast.
Detailed description of the invention
Below detailed description of the invention of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of detailed description of the invention; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection in appended claim.
With reference to figure 1, Fig. 1 shows evaporimeter liquefied ammonia recovery system structural representation, as shown in Figure 1, this evaporimeter liquefied ammonia recovery system comprises and is arranged on evaporimeter inside, spray head 6 for washing the liquefied ammonia in evaporimeter, is positioned at the liquid collecting funnel be connected immediately below spray head 6, with liquefied ammonia heat exchanger tube and the ammonia absorption cell 1 being arranged on evaporimeter side; Ammonia absorption cell 1 enters pipe 3 by liquid back pipe 2 and liquefied ammonia and is connected; Liquefied ammonia enters on pipe 3 and liquid back pipe 2 and is provided with valve 8.
When carrying out liquefied ammonia recovery, closedown liquefied ammonia enters the valve 8 on pipe 3, open the valve 8 on liquid back pipe 2, opening spray head 6 can be drained in liquefied ammonia heat exchanger tube by the solution of ejection in conjunction with liquid collecting funnel 5, liquefied ammonia heat exchanger tube is rinsed, solution after flushing enters ammonia absorption cell 1 by liquid back pipe 2, realizes the recovery to liquefied ammonia.
In an embodiment of the present utility model, evaporimeter liquefied ammonia recovery system also comprises air blast 10, and air blast 10 is connected with the ammonia vapour-discharge tube 7 of evaporimeter by blast pipe 9; Blast pipe 9 and ammonia vapour-discharge tube 7 are provided with valve 8.
Flushing liquor remaining in liquefied ammonia heat exchanger tube can be blown into ammonia absorption cell 1 by air blast 10 and arranging of blast pipe 9.During use, closedown ammonia vapour-discharge tube 7 and liquefied ammonia enter the valve 8 on pipe 3, open the valve 8 on liquid back pipe 2 and blast pipe 9, flushing liquor remaining in liquefied ammonia heat exchanger tube can be drained only.
In an embodiment of the present utility model, the bottom of liquid back pipe 2 is provided with one in netted cover body 4; The mesh size of cover body 4 is arranged on 2mm.The setting of cover body 4, increases the contact area of solution in flushing liquor and ammonia absorption cell 1, thus ensure that the abundant absorption of solution in flushing liquor and ammonia absorption cell 1.
In ammonia absorption cell 1, the solution of splendid attire is preferably pure water or dilute sulfuric acid.Liquefied ammonia, by after fully reacting with the pure water in ammonia absorption cell 1 or dilute sulfuric acid, as the solution of irrigating plant, thus can reach making full use of after the recovery of liquefied ammonia.
During design, the preferred upper end of liquid collecting funnel 5 and the madial wall of evaporimeter weld together, and the solution rinsing liquefied ammonia like this would not enter in the heat exchange structure of vaporizer lower end, ensure that the aridity of heat exchange structure place section, avoids heat exchange structure and be corroded.
In sum, can the solution of ejection be drained in liquefied ammonia heat exchanger tube by the spray head 6 arranged in evaporimeter inside in conjunction with liquid collecting funnel 5, rinse liquefied ammonia heat exchanger tube, the solution after flushing enters ammonia absorption cell 1 by liquid back pipe 2, realizes the recovery to liquefied ammonia.
