Abstract
The utility model discloses a be applied to heat transfer device of synthetic ammonia, including the support, install snakelike inner tube on the support, the straight tube of snakelike inner tube outward respectively the suit have the multilayer outer tube, the intercommunication has the branch pipe between two layers of adjacent outer tubes, the external diameter of multilayer outer tube is more than the straight tube internal diameter of snakelike inner tube. The utility model discloses simple structure has increased outer tube diameter size and pressure rating, has further increased the heat transfer area between inner tube and the outer tube, has improved the heat transfer effect, simultaneously because circulating water cooling water has been overcome in set phenomenon of intertube scale deposit to between inner tube and the outer tube the widening of space to the expense that produces every year has been practiced thrift because of the scale deposit pickling.
Description
Technical field
This utility model is related to synthesize the production equipment field of ammonia, specifically a kind of heat-exchanger rig for being applied to synthesize ammonia.
Background technology
In Ammonia Production field, heat-exchanger rig is one of common device.Existing such heat-exchanger rig, its trocar sheath
Caliber it is less, heat exchange area is 2.64m2, recirculated cooling water fouling, blocking are easily caused for a long time, so as to cause heat transfer effect
Difference；In addition, it is necessary to carry out regular snaking, need to carry out pickling to trocar sheath, and pickling once needs one to two working days, behaviour
Make bothersome laborious.
Utility model content
The purpose of this utility model be to provide it is a kind of be applied to synthesize ammonia heat-exchanger rig, increase trocar sheath diameter dimension and
Pressure rating, the further heat exchange area between increase inner tube and trocar sheath, to improve heat transfer effect, simultaneously because inner tube with it is outer
Space is widened between sleeve pipe, can overcome the phenomenon of circulation cooling water fouling between sleeve pipe such that it is able to save it is annual because
Fouling pickling and the expense that produces.
The technical solution of the utility model is as follows：
A kind of heat-exchanger rig for being applied to synthesize ammonia, includes support, it is characterised in that：Serpentiss are installed on described support
Shape inner tube, is respectively installed with multilamellar trocar sheath outside the straight tube of the coiled inner tube, between adjacent two layers of trocar sheath arm is communicated with,
Straight tube internal diameter of the external diameter of the multilamellar trocar sheath much larger than the coiled inner tube.
The described heat-exchanger rig for being applied to synthesis ammonia, it is characterised in that：The external diameter of the multilamellar trocar sheath is far described
1.4 times of the straight tube internal diameter of coiled inner tube.
The beneficial effects of the utility model：
This utility model simple structure, increases trocar sheath diameter dimension and pressure rating, further increase inner tube with
Heat exchange area between trocar sheath, heat exchange area increases to 8.6 m2, heat exchange area improves 3.2 times between pipe, intraductal heat exchange face
Product improves 1.32 times, improves heat transfer effect；Simultaneously because space is widened between inner tube and trocar sheath, recirculated water is overcome
The phenomenon of cooling water fouling between sleeve pipe, so as to save the expense for producing because of fouling pickling every year；Suitable for medium and small nitrogen fertilizer
The cooling of enterprise's unstripped gas, cooling, are equally applicable in the transformations of equipment such as chemical enterprise urea plant ammonia preheater, using front
Scape is very wide, and effect is very well, easy to use, practical, easy for installation, is worthy to be popularized.
Description of the drawings
Fig. 1 is this utility model structural representation.
Specific embodiment
Referring to Fig. 1, a kind of heat-exchanger rig for being applied to synthesize ammonia includes support 1, and on support 1 coiled inner tube is provided with
2, multilamellar trocar sheath 3 is respectively installed with outside the straight tube of coiled inner tube 2, arm 4 is communicated between adjacent two layers of trocar sheath, outside multilamellar
Straight tube internal diameter of the external diameter of sleeve pipe 3 much larger than coiled inner tube 2.
In this utility model, 1.4 times of the straight tube internal diameter of the external diameter far coiled inner tube of multilamellar trocar sheath.
Claims (2)
1. a kind of heat-exchanger rig for being applied to synthesize ammonia, includes support, it is characterised in that：It is provided with described support snakelike
Inner tube, is respectively installed with multilamellar trocar sheath outside the straight tube of the coiled inner tube, be communicated with arm between adjacent two layers of trocar sheath, institute
State the straight tube internal diameter of the external diameter much larger than the coiled inner tube of multilamellar trocar sheath.
2. it is according to claim 1 be applied to synthesize ammonia heat-exchanger rig, it is characterised in that：Outside the multilamellar trocar sheath
1.4 times of the straight tube internal diameter of the far described coiled inner tube in footpath.
