Brief description of the drawings
Fig. 1 is the structural representation of the spraying condenser made of tin-brass alloy in the prior art；
Fig. 2 is the structural representation of return bend in the prior art；
Fig. 3 is the structural representation of the spraying condenser made of tin-brass alloy in the utility model embodiment.
Embodiment
The utility model preferred embodiment is elaborated below in conjunction with the accompanying drawings.
One kind spraying condenser, its exterior contour made of tin-brass alloy is provided in the present embodiment to may be referred to
Prior art is Fig. 1, includes support, and the support is made up of two tin brass tubes being parallel to each other 1, and one-ton brass is in copper zinc
The brass of tin is added on the basis of alloy.One-ton brass is corrosion-resistant in fresh water and seawater, general term admirality brass.General one-ton brass contains
Tin amount is 1%, stanniferous excessive, drops low-alloyed plasticity.By the zinc content in alloy, it is divided into α one-ton brass, (alpha+beta) one-ton brass.It is single
Phase one-ton brass such as 70Cu-29Zn-1Sn, there is good mechanical property, the tensile strength of soft state is 350MPa, and elongation is
60%, excellent cold-workability exhibiting, hot rolling and hot extrusion can be born, but can not heat punching and hot forging.It is widely used in ship, the height of steam power plant
Strong anti-corrosion condenser pipe.Such a alloy has a stress-corrosion cracking tendency, thus the tubing of cold working must process annealing should to eliminate
Power.(alpha+beta) one-ton brass such as 62Cu-37Zn-1Sn, there is a good mechanical property, and the tensile strength of soft state is 380MPa, elongation percentage
40%, hot and cold pressure processing can be carried out, Cutting free, weldability is good, there is higher corrosion resistance in the seawater, suitable for ship zero
Part, the part with the contact such as seawater, gasoline.
The length of two tin brass tubes is identical, is carry jointly at the top of two tin brass tubes for making cooling water
The device tank 2 uniformly sprayed, the bottom of tank have opened up multiple fluid holes, and structure is similar to gondola water faucet, and such water can be by weight
Power is uniformly sprayed from fluid hole.Rhone 8 is connected to jointly in the bottom of two tin brass tubes, in tank and rhone
Between be from top to bottom equally spacedly provided with some straight tubes 3 being parallel to each other（Heat exchanger tube）, and these straight tubes are in same vertical
In plane, during work, cooling water in device tank uniformly spray and under, contacted with heat exchanger tube cool down after fall on
It is collected in rhone, in order to prevent cooling water to be splashed to the outside of rhone, the width of rhone will much wide and device
The width of tank 2.
Gas outlet tube 4 is connected in one end of that root straight tube of the top, is opened up in one end of bottom that root straight tube
Gas feed 5, except the above-described end for being connected to gas outlet tube and in addition to opening up the end of gas feed,
It is connected between the end of other two straight tubes of arbitrary neighborhood by return bend 6, because place limited height, connection same column are straight
The bending radius of the return bend of pipe is unsuitable excessive (R is no more than 200mm), furthermore bending radius crosses conference influence heat transfer effect.
In the requirement for combining manufacture and examining, the present embodiment proposes U-bend header structure as shown in Figure 3, and two string of pipe are misplaced and flowed
Logical, corresponding tube pitch is changed to 150mm, is 175mm so as to the bending radius of increased return bend.System is simmered during processing in advance
180 ° of elbows, while straight length should be reserved and at least exceed 50mm, then formed with straight tube welding.This kind of return bend structure stress
It is good, high pressure can be born, meets the operating mode of the spraying condenser.
Foregoing gas outlet tube extends vertically from top to bottom, probably extends to a second from the bottom from the bottom up straight tube left side
The right side, some interface tubes are opened up on gas outlet tube, it is corresponding on each interface tube to be connected to a return duct 7, return
Flow tube one end is connected on gas outlet tube, and the other end is connected on that nearest root return bend of oblique upper.Gas outlet tube connects
Then ammonia storage tank（Not shown in figure）.The purpose of this structure design be in order to reduce gas ammonia, the liquefied ammonia mixed flow in pipe,
The present embodiment in the elbow of every string of pipe by setting return duct so that liquefied ammonia is through in return line flow to ammonia storage tank, eliminating
Gas ammonia rises resistance, ensures condensation effect.
It is described above to make preferred embodiment of the present utility model, do not depart from for the person of ordinary skill of the art
On the premise of the utility model principle, some variations and modifications can also be made, these also should be regarded as protection of the present utility model
Scope.
