Detailed description of the invention
The utility model discloses a kind of liquid distributing device, so that fluid is uniformly distributed, improve heat exchange efficiency.This utility model
Also disclose a kind of shell-and-tube heat exchanger.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
As shown in Figures 1 and 3, a kind of feed liquor for being arranged on shell-and-tube heat exchanger that this utility model embodiment provides
Liquid distributing device in chamber 5, including liquid separatnig plate 1 and the liquid separating port 2 that is arranged on liquid separatnig plate 1.Liquid distributing device is being arranged on shell
After in the admission chamber 5 of formula heat exchanger, liquid separatnig plate 1 covers on the mouth of pipe of the heat exchanger tube 7 of admission chamber 5；Liquid separating port 2 and heat exchanger tube 7
One_to_one corresponding is arranged, i.e. a liquid separating port 2 is only correspondingly arranged with a heat exchanger tube 7, and, a heat exchanger tube 7 is at most only with one
Individual liquid separating port 2 is correspondingly arranged.Further, the circulation area of liquid separating port 2 is less than the circulation area of heat exchanger tube 7.
This utility model embodiment provide liquid distributing device, in the admission chamber 5 being installed on shell-and-tube heat exchanger after, due to
Liquid separatnig plate 1 covers on the mouth of pipe of the heat exchanger tube 7 of admission chamber 5, and fluid is entered admission chamber 5 by the feed tube 8 of shell-and-tube heat exchanger
After, need the liquid separating port 2 on liquid separatnig plate 1, enter back into heat exchanger tube 7.Owing to the circulation area of liquid separating port 2 is less than heat exchanger tube 7

The one side of heat pipe 7.By above-mentioned setting so that fluid cannot flow in separating tube 3 along the outer surface of liquid separatnig plate 1, needs to make stream
Body just flows into separating tube 3 after being uniformly distributed in admission chamber 5.Improve fluid further and enter the uniformity coefficient of every heat exchanger tube 7.
Preferably, separating tube 3 seals and is arranged in liquid separating port 2.That is, fluid is only capable of flowing into heat exchanger tube 7 by separating tube 3
In, improve the effect of convection cell drain.Can also make to there is gap between the outer wall of separating tube 3 and the inwall of liquid separating port 2, stream
Body is entered in heat exchanger tube 7 by gap and separating tube 3 homomergic flow.
In the present embodiment, separating tube 3 is connected with liquid separatnig plate 1 by welding, it is also possible to connected by interference fit or screw thread
The mode such as connect is arranged in liquid separating port 2, reaches the connection effect of separating tube 3 and liquid separatnig plate 1.
In the liquid distributing device that this utility model embodiment provides, separating tube 3 is perpendicular to liquid separatnig plate 1.Due to pipe shell type heat exchange
The tube sheet 6 of device is mutually perpendicular to heat exchanger tube 7, and the separating tube 3 of liquid distributing device is perpendicular to liquid separatnig plate 1, in installation process, in order to
By parallel with tube sheet 6 for liquid separatnig plate 1 laminating, it is simple to connect.Separating tube 3 can also be distributed in certain acute angle with liquid separatnig plate 1, when
So, separating tube 3 is parallel to each other, in installation process, and liquid separatnig plate 1 and tube sheet 6 setting in a certain angle.
The outer wall of separating tube 3 is the contact surface for contacting with the inwall of heat exchanger tube 7.That is, liquid distributing device is installed on pipe
After in the admission chamber 5 of shell heat exchanger, separating tube 3 inserts in heat exchanger tube 7, and, the outer wall of separating tube 3 is interior with heat exchanger tube 7
Wall contacts, in order to support mutually between separating tube 3 and heat exchanger tube 7, and the structure further increasing shell-and-tube heat exchanger is steady
Qualitative.
Bolt fixing hole 4 it is provided with on liquid separatnig plate 1.By arranging bolt so that it is with shell-and-tube after bolt fixing hole 4
The tube sheet 6 of heat exchanger connects, it is achieved that the installation of liquid distributing device is fixed.It is easy to maintenance and the maintenance of liquid distributing device.Can also lead to
Cross and the mode such as weld or snap connection and complete the installation of liquid distributing device and fix, and all within protection domain.
This utility model embodiment additionally provides a kind of shell-and-tube heat exchanger, including the most above-mentioned any one liquid distributing device A.As
Shown in Fig. 3, owing to above-mentioned liquid distributing device A has above-mentioned technique effect, the shell-and-tube heat exchanger with above-mentioned liquid distributing device A also should
