Description

Technical Field

[0001] The invention belongs to the technical field of heat exchangers, and in particular relates to an environmentally friendly high-efficiency heat exchanger for petrochemical industry. Background Art

[0002] Heat exchangers are devices that transfer part of the heat of hot fluid to cold fluid, also known as heat exchangers. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. When a chemical heat exchanger is working, it usually continuously puts hot fluid into the shell side, and at the same time puts the chemical petroleum raw materials that need heat exchange treatment into the tube side, and heat exchange treatment is carried out through the circulation of petroleum raw materials and heat medium.

[0003] The shell-and-tube heat exchanger is the most widely used heat exchanger in chemical production. During heat exchange, a fluid enters from one end of the shell-and-tube heat exchanger, passes through the heat exchange tubes, and flows out from the other end; similarly, another fluid enters from one end of the shell and flows out from the other end of the shell. The shell-and-tube heat exchanger in the prior art often has only one inlet and outlet at the cold end or hot end. When adjusting the medium temperature at the outlet end of the shell-and-tube heat exchanger, it often takes a long time to change the medium flow rate and medium temperature to achieve accurate adjustment of the output temperature. However, this method is inefficient, especially for large shell-and-tube heat exchangers with a capacity of more than 700 cubic meters. The time to complete the medium temperature adjustment is often more than 10 minutes.

DETAILED DESCRIPTION

[0020] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0021] Example 1 like Figure 1 to Figure 2 As shown, this embodiment designs an environmentally friendly and efficient heat exchanger for petrochemical industry, including a heat exchange shell 1 and an external piping system 3.

[0022] The heat exchange shell 1 includes components such as an end shell 11, a conversion shell 12, an isolation plate 16, a heat exchange tube 17 and a main shell 13. The main shell 13 is a flat tube structure, and the width of the main shell 13 is greater than its height. When the cold end inlet and the cold end outlet 15 are located in the same direction of the main shell 13, the vertical climbing height of the medium can also be reduced, so that the heat exchange effects of the heat exchange tubes 17 at different heights are more similar.

[0023] Cold end inlets 14 are arranged on the lower side walls at both ends of the main shell 13, and a cold end outlet 15 is arranged on the side wall in the middle of the main shell 13; water medium can enter from the two cold end inlets 14 and then flow out from the cold end outlet 15. The structural design of two cold end inlets and one cold end outlet 15 can not only increase the heat exchange efficiency through the turbulence generated by the collision of the medium flow at the cold end outlet 15, but also can control the flow at the two cold end inlets, which is beneficial to control the heat exchange effect and achieve the effect of precise control of the medium output temperature.

[0024] End shells 11 are provided at both ends of the main shell 13 , and a hot end inlet and a hot end outlet are provided on the two end shells 11 , respectively. The liquid medium of petrochemical industry flows in from the hot end inlet and flows out from the hot end outlet, and exchanges heat with the water medium in the heat exchange tube 17 .

[0025] The end shell 11 is a round cover structure, so that the existing end shell 11 products can be directly used to reduce the production and application costs. The end shell 11 is connected to the main shell 13 through a respective conversion shell 12. One end of the conversion shell 12 is a circular opening to facilitate the connection with the end shell 11, and the other end of the conversion shell 12 is a flat opening to facilitate the connection with the end of the main shell 13. Two isolation plates 16 are respectively arranged at both ends of the main shell 13, and a number of heat exchange tubes 17 are connected between the two isolation plates 16; the tube cavity of the heat exchange tube 17 is connected to the hot end inlet and the hot end outlet. The edge of the isolation plate 16 is sealed and connected to the main shell 13, so that the isolation plate 16 can separate the chambers on its left and right sides. At the same time, the isolation plate 16 is also connected to the end of the heat exchange tube 17, so that the medium in the heat exchange tube 17 can flow out or flow into the side of the isolation plate 16 away from the heat exchange tube 17.

[0026] The external piping system 3 includes a booster pump 31, a solenoid valve 32 and a water pump 33; the water outlet of the booster pump 31 is connected to the two cold end inlets 14 through respective solenoid valves 32, and the water inlet of the water pump 33 is connected to the cold end outlet 15. The power of the booster pump 31, the power of the water pump 33 and the opening of the solenoid valve 32 can be controlled by a PLC controller or an industrial computer; the PLC controller or industrial computer can control the flow at different cold end inlets by controlling the opening of the solenoid valve 32 at the cold end inlet, which is beneficial to controlling the heat exchange effect and achieving the effect of precise control of the medium output temperature.

[0027] The main shell 13 is provided with a ring tube 2, which is connected to the cold end outlet 15 at the lower part of the ring tube 2. A plurality of through holes are provided on the tube wall of the ring tube 2. The higher the position of the through hole is, the larger the aperture of the through hole is. Thus, water entering the cold end inlet can flow to the through holes at different heights, thereby ensuring that the heat exchange effects of different heat exchange tubes 17 in the vertical direction are more similar.

[0028] Example 2 like Figures 1 to 6 As shown, the structure in this embodiment is designed based on the structure of embodiment 1.

[0029] An outlet cover 5 is arranged on the inner wall of the main shell 13. The outlet cover 5 is arched. Both ends of the outlet cover 5 are connected to the inner wall of the main shell 13.

The left and right sides of the outlet cover 5 are provided with lateral openings. The lower part of the annular tube 2 extends into the outlet cover 5 from the lateral openings. A larger hollow hole is arranged on the lower side wall of the annular tube 2, so that the cover cavity of the outlet cover 5 is connected to the cold end outlet 15, so that the medium in the annular tube 2 flows into the outlet cover 5 and then flows out from the cold end outlet 15. The annular tube 2 is slidably matched with the outlet cover 5, and the tube cavity of the annular tube 2 is connected to the cover cavity of the outlet cover 5. Since the annular tube 2 can be moved in the left and right directions in the main shell 13, the distance between the annular tube 2 and the two cold end inlets can be changed as needed, so that the water medium entering the two cold end inlets can be mixed at different positions, which is more convenient for accurate temperature control at the outlets of the cold end and the hot end.

[0030] like Figure 5 As shown, a plurality of folding baffles 51 are provided on the side of the outlet cover 5, and the folding baffles 51 are provided at the lateral opening, one end of the folding baffle 51 is fixedly connected to the end of the outlet cover 5, and the other end is connected to the tube wall of the ring tube 2; when the ring tube 2 slides along the length direction of the outlet cover 5 (that is, when it slides along the lateral opening), part of the folding baffles 51 are stretched, and the other part of the folding baffles 51 are compressed.

Each transverse screw rod 46 vertically passes through the ring tube 2 and is threadedly matched with the tube wall of the ring tube 2, so that when the transverse screw rod 46 rotates, it can control the ring tube 2 to slide left and right. The plurality of first synchronous wheels 44 correspond to the plurality of transverse screw rods 46 one by one, and the first synchronous wheel 44 is coaxially connected to one end of the corresponding transverse screw rod 46 and meshes with the first synchronous belt 45. When the first synchronous belt 45 is driven, each transverse screw rod 46 can rotate in the same manner. In addition, a guide wheel can be provided on the inner wall of the main housing 13 to guide the first synchronous belt 45 so that the first synchronous belt 45 is closer to the inner wall of the main housing 13 .

[0032] The transverse movement control mechanism 4 also includes components such as a first operating rod 41, a first bevel gear 42 and a first bevel gear 43; the first operating rod 41 is rotatably arranged on the side wall of the main housing 13, one end of the first operating rod 41 extends outside the main housing 13, and the other end extends into the main housing 13, the first bevel gear 42 is coaxially connected to the first operating rod 41, when the first operating rod 41 is manually rotated, the first bevel gear 42 rotates synchronously, the first bevel gear 43 is coaxially connected to one of the transverse movement screws 46, and the first bevel gear 43 is meshed with the first bevel gear 42, so as to facilitate the use of the first operating rod 41 to control the lateral movement position of the ring tube 2.

[0034] A spoiler mechanism 6 is provided on the inner ring side of the ring tube 2, and the spoiler mechanism 6 includes a spoiler strip 66, which is a flat strip structure, and the spoiler strip 66 passes through the gap between the heat exchange tubes 17, and the upper end of the spoiler strip 66 is connected to the top of the ring tube 2, and the lower end of the spoiler strip 66 is connected to the bottom of the ring tube 2. The spoiler strip 66 can decelerate the water medium, so that the water medium can collide better at the ring tube 2 to form a spoiler, thereby improving the heat exchange effect of the heat exchange tube 17.

[0035] like Figure 7 As shown, the spoiler mechanism 6 includes an upper shell seat 61, an upper cone disk 62, a second synchronous belt 63, an upper synchronous gear 64, an upper bevel gear 65, a lower shell seat 67, a lower cone disk 68, a lower bevel gear, a lower synchronous gear 69 and other components.

[0039] The two ends of the upper shell seat 61 and the lower shell seat 67 can be connected by two arc tubes, so that the four are connected in a ring shape. The upper shell seat 61, the lower shell seat 67, and the arc tube can be provided with guide wheels for guiding the second synchronous belt 63.
