Description

Technical Field

[0001] The utility model relates to the field of chemical equipment, in particular to an adjustable polytetrafluoroethylene condenser structure. Background Art

[0002] In the application of chemical equipment, since most highly corrosive media cannot directly contact steel equipment, they need to be isolated with the help of PTFE materials. However, due to the certain shrinkage of PTFE materials themselves, they will shrink with the temperature during heat exchange, causing the PTFE heat exchange tubes to squeeze and deform each other. In addition, the temperature difference of the condenser is too large. When the heat exchange tube expands, the heat exchange tube arches between the baffles under the action of thermal stress, and the long-term friction with the inner wall of the shell will cause the heat exchange tube to wear, thereby affecting the normal operation of the equipment.

[0003] In summary, the utility model designs an adjustable polytetrafluoroethylene condenser structure. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of the present invention is to provide an adjustable PTFE condenser structure, which can reduce the impact of deformation of PTFE materials caused by thermal stress on the equipment and extend the service life of the equipment.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: an adjustable polytetrafluoroethylene condenser structure, including a head, an equipment flange, a heat exchange tube bundle assembly, a cylinder, a support component, a compensator, a screw, a nut, a corrugated hose and a connecting flange. The cylinder is connected to the compensator through a connecting flange, and the cylinder and the compensator are also connected through a nut and a screw. A support component is also provided on the outside of the cylinder. The two ends of the cylinder are connected to the head through the equipment flange. A heat exchange tube bundle assembly is provided in the cylinder, and the outer wall of the compensator is a corrugated hose.

[0006] Preferably, the support assembly is located outside the compensator.

[0007] Preferably, the corrugated hose is provided with a stainless steel braided mesh on the outside to increase strength.

[0008] Preferably, the compensator is arranged in the middle of the cylinder.

[0009] The beneficial effects of the present invention are as follows: the present invention adds a compensator to a conventional condenser. When the condenser is in operation, the length of the compensator is adjusted, thereby controlling the shrinkage of the PTFE heat exchange tubes inside the condenser. When the equipment is maintained, the length of the compensator is readjusted, thereby allowing the PTFE heat exchange tubes inside the condenser to return to their initial state as much as possible. This reduces the impact of thermal stress on the PTFE material on the equipment, and extends the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments;

[0011] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0012] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0013] Reference Figure 1 This specific embodiment adopts the following technical solution: an adjustable polytetrafluoroethylene condenser structure, including a head 1, an equipment flange 2, a heat exchange tube bundle assembly 3, a cylinder 4, a support component 5, a compensator 6, a screw 7, a nut 8, a corrugated hose 9 and a connecting flange 10. The cylinder 4 is connected to the compensator 6 through the connecting flange 10, and the cylinder 4 and the compensator 6 are also connected through a nut 8 and a screw 7. A support component 5 is also provided on the outside of the cylinder 4. Both ends of the cylinder 4 are connected to the head 1 through the equipment flange 2. A heat exchange tube bundle assembly 3 is provided inside the cylinder 4, and the outer wall of the compensator is a corrugated hose 9.

[0014] It is worth noting that the support assembly 5 is located outside the compensator 6.

[0015] It is worth noting that the corrugated hose 9 is provided with a stainless steel braided mesh on the outside to increase the strength.

[0016] In addition, the compensator 6 is arranged in the middle of the cylinder 4.

[0017] In this specific embodiment, the heat exchange tube bundle assembly 3 is arranged in the cylinder 4 to realize heat exchange during the condensation process. The heat exchange tube bundle assembly 3 is the core component of the condenser, and realizes heat transfer through the temperature difference between the cooling medium inside it and the external medium. The cylinder 4 serves as the outer shell of the entire condenser, accommodating the internal heat exchange tube bundle assembly 3 and connected to the head 1 through the equipment flange 2. The support component 5 is located on the outside of the compensator 6, and is used to support and fix the cylinder 4 and the compensator 6 to ensure that they remain stable during operation. The compensator 6 is used to compensate for the thermal expansion and contraction caused by temperature changes, and avoid damage to the equipment due to temperature changes. The outer wall of the compensator 6 is a corrugated hose 9 with good elasticity and scalability. The screw 7 and the nut 8 are used to connect the cylinder 4 and the compensator 6 to ensure a tight connection between the two, while allowing a certain degree of adjustment to adapt to different working conditions.

[0018] The outer wall of the compensator 6 is made of a corrugated hose 9, which effectively absorbs expansion and contraction caused by temperature changes, increasing the flexibility and durability of the equipment. A stainless steel braided mesh is installed on the outside of the corrugated hose 9 to increase its strength and prevent it from rupturing under high pressure or high temperature conditions.

[0019] The condenser and compensator of this specific embodiment are connected by a connecting flange, and the gap between the compensator and the condenser is controlled by a screw and a nut. When the condenser needs to work, the compensator is adjusted first, and then the support assembly welded to the outer part of the cylinder is adjusted to change the gap between the condenser and the compensator, thereby affecting the internal heat exchange tube bundle and reducing the deformation caused by thermal stress. Similarly, after the equipment operation is completed, the support assembly and the compensator are adjusted again to restore the heat exchange tube bundle inside the condenser to its initial state, minimizing the deformation of the heat exchange tube.

[0020] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
