Abstract
The utility model discloses a self-evaporation structure for deposited liquid ammonia in a gas ammonia delivery pipe. The self-evaporation structure comprises the gas ammonia delivery pipe (1), wherein a liquid ammonia deposition pipe (2) is arranged at the bottom of the gas ammonia delivery pipe (1); and a heating device (3) is arranged outside the liquid ammonia deposition pipe (2). Deposited liquid ammonia in the gas ammonia delivery pipe is collected in the pipe, heated to evaporate into gas ammonia, and enters the gas ammonia delivery pipe to participate in a working cycle or be recycled. The liquid ammonia automatically flows into the liquid ammonia deposition pipe by virtue of flowability of liquid, additional equipment is not needed, the liquid ammonia can be evaporated so long as the heating device is started, the whole operation process is simple and feasible, the equipment cost is low, and the using effect is good.
Description
Technical field
The utility model relates to gas ammonia conveying technology field, deposition liquefied ammonia spontaneous evaporation structure in especially a kind of gas ammonia carrier pipe.
Background technology
At present, in production of synthetic ammonia, liquefied ammonia is realized the cool cycles utilization as evaporation, compression and the liquefaction that cooling medium passes through repeatedly.But in process of production, the gas ammonia carrier pipe may be brought liquefied ammonia into because of abnormal operation, and deposition appears in liquefied ammonia in the gas ammonia carrier pipe, can damage pipe support by pressure when serious, causes pipeline to damage.And if the liquefied ammonia that has deposited do not establish is led pouring and then is difficult to derive, and going wrong is difficult for maintenance, is difficult for displacement, brings difficulty for processing subsequently.The method of the liquefied ammonia that deposits in handling the gas ammonia carrier pipe is at present, leads pouring in the low spot setting of gas ammonia carrier pipe, the discharging of guiding liquefied ammonia.But such method need add pumping installations, causes safety place but also will set up the longer pipe road.So not only increased equipment investment, and complex operation, effect is also undesirable simultaneously.
Summary of the invention
The purpose of this utility model is: deposition liquefied ammonia spontaneous evaporation structure in a kind of gas ammonia carrier pipe is provided, and it can effectively solve the problem of deposition liquefied ammonia in the gas ammonia carrier pipe, and simple in structure, equipment drops into low, easy and simple to handle, treatment effect is good, to overcome the deficiencies in the prior art.
The utility model is achieved in that deposition liquefied ammonia spontaneous evaporation structure in the gas ammonia carrier pipe, comprises the gas ammonia carrier pipe, is provided with the liquefied ammonia deposited tube in the bottom of gas ammonia carrier pipe, is provided with heater in liquefied ammonia deposited tube outside.
Be connected with the gas ammonia recovery tube at the gas ammonia carrier pipe.Generally, the liquefied ammonia of evaporation can enter in the production cycle, still, makes at the liquefied ammonia that is in end-of-life state and need to handle deposition, and the liquefied ammonia of evaporation can enter ammonia recovery unit by the gas ammonia recovery tube.
The liquefied ammonia deposited tube is more than one.According to the laying condition of pipeline, easily on the position of deposition liquefied ammonia corresponding liquefied ammonia deposited tube is set at each, can avoid that so also all liquefied ammonia are concentrated on the pipeline minimum point and evaporate and cause the situation that evaporation capacity may deficiency.
Be provided with fluid level indicator at the liquefied ammonia deposited tube.
Described heater is jacket type or coiled, or electrical heating type.The thermal source of jacket type or coiled can adopt steam.
Heater is the steam coil pipe, and the one end is the steam inlet, and the other end is condensate outlet, is provided with steam trap at condensate outlet.
Owing to adopted technique scheme, compared with prior art, the utility model converges the liquefied ammonia that deposits in the gas ammonia carrier pipe in pipeline, makes liquefied ammonia be evaporated to gas ammonia by heating then, enter again in the gas ammonia carrier pipe and participate in working cycles, or reclaim.The utility model utilizes the self drainage of liquid that liquefied ammonia is flowed in the liquefied ammonia deposited tube voluntarily, need not to use extra equipment, only needs to start heater and can make the liquefied ammonia evaporation, and the whole operation process is simple, and equipment cost is low, and result of use is good.The utility model is simple in structure, makes easily, and with low cost, result of use is good.
