Description

A heat exchange tube bundle support device

technical field

The utility model relates to a heat exchange device, in particular to an evaporator in liquid preparation, alkali solidification equipment and liquid purification equipment such as chemical industry and petrochemical industry.

Background technique

In the process of liquid preparation, solid alkali or other liquid purification, due to the chemical process or product concentration requirements, the shell-side medium in the heat exchange component needs to achieve a stable large flow rate to ensure a certain flow area. Therefore, the general baffle type cannot be used. However, since there is no support in the middle of the several-meter-long heat exchange tube bundle, the heat exchange tube bundle will vibrate greatly during the operation of the equipment, which will affect the normal operation of the equipment.

Utility model content

The technical problem to be solved by the utility model is to provide a support device for the heat exchange tube bundle in the liquid purification and evaporation device, which can reduce the vibration of the heat exchange tube bundle without affecting the flow area of the shell side, so that the equipment can work stably and normally.

In order to solve the above problems, the utility model provides a heat exchange tube bundle support device, which is placed inside the shell of the evaporator, including a support ring 2, several connecting plates 1 and a prismatic screen frame support frame 3. Each heat exchange tube in the heat pipe bundle passes through the prismatic grid in the support frame 3 respectively; the prismatic screen frame support frame 3 is fixedly connected to the inner wall of the support ring 2; , one end is fixedly connected to the outer wall of the support ring 2, and the other end is fixedly connected to the inner wall of the shell of the evaporator.

As an improvement of the utility model, the prismatic screen frame support frame 3 is composed of several connecting pieces 4, and each connecting piece 4 has several strip-shaped openings with an angle of 60 degrees to its plane and a width of 3. The connecting pieces 4 The prismatic sieve frame support frame 3 is formed by evenly intersecting each other through strip-shaped openings.

As a further improvement of the utility model, the connecting plate 1, the support ring 2 and the connecting piece 4 are metal plates.

This heat exchange tube bundle supporting device plays a supporting role for the heat exchange tube bundle to reduce vibration and run stably without affecting the fluidity of the medium in the shell side, and the medium flow resistance is reduced to the minimum, which meets the requirements of the chemical process. Require and ensure that material characteristics meet product quality. Moreover, the structure is reasonable, the processing and manufacturing are simple, the cost is low, and the installation is convenient; the structure is stable, the bearing capacity is strong, and the service life is long.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.

Fig. 1 is the front view of the utility model.

Detailed ways

Below in conjunction with accompanying drawing for further detail:

As shown in Figure 1, the utility model is placed inside the shell of the evaporator, including a support ring 2, several connecting plates 1 and a prismatic screen frame support frame 3, and each heat exchange tube in the heat exchange tube bundle passes through the Through the prismatic grid in the support frame 3; the prismatic screen frame support frame 3 is fixedly connected to the inner wall of the support ring 2; several connecting plates 1 are evenly distributed along the outer circumference of the support ring 2, and one end is fixedly connected to the outer wall of the support ring 2 The other end is fixedly connected with the inner wall of the shell of the evaporator.

Preferably, the prismatic screen frame support frame 3 is composed of several connectors 4, and each connector 4 is evenly opened with several strip-shaped openings at an angle of 60 degrees to its plane and a width of 3 mm. 4. A prismatic screen frame support frame 3 formed by evenly intersecting each other through bar-shaped openings.

Further preferably, the connecting plate 1 , the supporting ring 2 and the connecting piece 4 are metal plates.

The heat exchange tube bundle support device described above in relation to the present invention is only used to illustrate the present invention and not to limit the technical solution described in this embodiment. Those of ordinary skill in the art should understand that the utility model can still be modified or equivalently replaced to achieve the same technical effect, as long as the application requirements are met, all within the protection scope of the utility model.
