Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, and in particular relates to a condensation tank. Background Art

[0002] The condenser can be used to cool and depressurize high-temperature and high-pressure steam, and the condensate can be recovered. The existing technology is usually set as a whole section of heat exchange tube. During the heat exchange process, the condensate continues to absorb heat from the inlet to the outlet. The temperature of the condensate near the outlet is higher, resulting in lower heat absorption at the outlet and poor condensation effect. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model provides a condensing tank. The condensing tank provided by the utility model can improve the heat exchange condensation effect.

[0004] The technical solution provided by the utility model is as follows:

[0005] A condensation tank, comprising, from inside to outside:

[0006] Internal heat conduction tank;

[0007] A plurality of sections of heat exchange pipes are arranged sequentially around the tank wall of the inner heat conduction tank from top to bottom;

[0008] External insulation tank;

[0009] A first pipe is vertically arranged between the inner heat-conducting tank and the outer heat-insulating tank, the first pipe is connected to one end opening of each of the heat exchange tubes, the upper end of the first pipe is a coolant outlet, and the lower end of the first pipe is blocked;

[0010] A second pipe is vertically arranged between the inner heat-conducting tank and the outer heat-insulating tank, the second pipe is connected to the other end opening of each heat exchange tube, the upper end of the second pipe is a coolant inlet, and the lower end is blocked, the coolant inlet is connected to a water inlet pump, and the water inlet pump is connected to a coolant pipe;

[0011] A steam inlet pipe, which is located at the bottom of the condensing tank, passes through the outer insulation tank and is connected to the inner heat conduction tank;

[0012] And a water outlet is arranged at the bottom of the outer heat-insulating tank and communicated with the inner heat-conducting tank.

[0013] Based on the above technical solution, by setting multiple sections of heat exchange tubes in parallel, the coolant in each section of the heat exchange tube is at the initial temperature, so that each section of the internal heat transfer tank can fully exchange heat. Compared with the prior art, in which the temperature in the entire heat exchange tube gradually increases, this technical solution can improve the condensation effect.

[0014] Specifically, a vacuum is provided between the inner heat-conducting tank and the outer heat-insulating tank.

[0015] Based on the above technical solution, the thermal insulation effect between the inner heat conduction tank and the outer insulation tank can be improved, which is also beneficial to improving the heat exchange and condensation effect of the heat exchange tube.

[0016] Specifically, a plurality of baffles are arranged in each of the inner heat-conducting tanks along the vertical direction.

[0017] Based on the above technical solution, the residence time of high-temperature steam can be extended to make heat exchange and condensation more complete.

[0018] Specifically, each of the baffles is arranged to be inclined toward the bottom of the inner heat-conducting tank, and the end of the baffle away from the inner wall of the inner heat-conducting tank coincides with the center line of the inner heat-conducting tank.

[0019] Based on the above technical solution, the liquefied high-temperature steam can flow along the baffle to the bottom of the inner heat transfer tank, come into contact with the steam during the flow, and take away the heat of the high-temperature steam, thereby improving the condensation effect.

[0020] Specifically, each baffle is provided with a hole.

[0021] Based on the above technical solution, the resistance of the steam can be reduced by passing through the holes during the steam's re-ascent process.

[0022] Specifically, the baffles are symmetrically and staggeredly arranged along the inner wall of the pipeline.

[0023] Based on the above technical solution, the liquefied water can be guided, and the liquefied water contacts the rising steam in the process of flowing to the bottom of the inner heat transfer tank to take away part of the heat, thereby improving the heat exchange condensation effect.

[0024] Specifically, the opening of each heat exchange tube communicating with the first pipeline is higher than the opening of each heat exchange tube communicating with the second pipeline.

[0025] Based on the above technical solution, the coolant in the second pipe can pass through each heat exchange tube by overflow, thereby reducing the flow rate and improving the heat exchange condensation effect.

[0026] The condensing tank provided by the utility model has multiple sections of parallel heat exchange tubes, so that the condensate in each section of the heat exchange tube, and thus the condensate in each part of the inner heat conduction tank, has the same initial temperature, thereby improving the condensation effect.

[0031] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] It should be noted that when a part or component is considered to be "connected", "located", or "assembled" on another part or component, it may be directly disposed on the other part or component or there may be a central part or component at the same time. The terms "left", "right", "upper", "lower" and similar expressions used herein are for illustrative purposes only.

[0033] In a specific embodiment, Figure 1 As shown, the condensing tank includes: an inner heat-conducting tank 1; a plurality of sections of heat exchange tubes 2 arranged around the tank wall of the inner heat-conducting tank 1 from top to bottom; an outer heat-insulating tank 3; a vertically arranged first pipe 4, the first pipe 4 is connected to one end opening of each heat exchange tube 2, the upper end of which is a coolant outlet, and the lower end of which is blocked; a vertically arranged second pipe 5, the second pipe 5 is connected to the other end opening of each heat exchange tube 2, the upper end of which is a coolant inlet, and the lower end of which is blocked; a steam inlet pipe 7, which is located at the bottom of the condensing tank and passes through the pipe walls of the outer heat-insulating tank 3 and the inner heat-conducting tank 1 in sequence, and is connected to the inner heat-conducting tank 1; a bottom coolant outlet 6; and a water inlet pump connected to the inlet of the second pipe 5.

[0034] Based on this technical solution, each heat exchange tube 2 is arranged in parallel and directly connected to the condensate pipeline, so that the coolant in each section of the heat exchange tube 2 is at the initial temperature, and each section of the heat exchange tube 2 can fully exchange heat, thereby improving the heat exchange condensation effect.

[0035] The steam inlet pipe 7 is arranged at one side of the bottom of the outer heat-insulating tank 3. The arrangement of the steam inlet pipe 7 can avoid the arrangement position of the heat exchange tube.

[0036] Example 2

[0037] Based on the above specific implementation, the area between the inner heat-conducting tank 1 and the outer insulation tank 3 is set as a vacuum area to improve the insulation effect between the inner heat-conducting tank 1 and the outer insulation tank 3, and to improve the heat exchange and condensation effect of the heat exchange tube 2.

[0038] Example 3

[0039] Based on the above specific implementation methods, Figure 2 As shown, a plurality of baffles 8 are arranged along the pipes in each heat exchange tube 2. The baffles 8 can be arranged horizontally or tilted to reduce the flow rate, prolong the residence time of high-temperature steam, and improve the heat exchange condensation effect. The baffles 8 are arranged tilted so that the liquefied water of the steam can flow along the baffles 8 to the bottom of the inner heat conduction tank 1, and contact with the steam during the flow process to take away a certain amount of heat.

[0040] Example 4

[0041] On the basis of Example 3, Figure 2 As shown, the baffles 8 are symmetrically and staggeredly arranged along the inner wall of the pipe, increasing the distance that the cold water flows through the heat exchange tube 2 and improving the heat exchange and condensation effect. The baffles 8 are inclined and staggered, so that the liquefied water of the steam can flow along the baffles 8 to the bottom of the inner heat conduction tank 1 more fully, and contact with the steam during the flow process to take away a certain amount of heat.

[0042] Example 5

[0043] On the basis of Example 3, Figure 2 As shown, each baffle 8 is provided with holes, which can reduce the resistance of steam and facilitate the upward flow of steam.

[0044] Example 6

[0045] On the basis of Example 3, each baffle plate 8 may be further provided with a guide groove to reduce the flow velocity and improve the heat exchange condensation effect.

[0046] Example 7

[0047] Based on the above specific implementation methods, Figure 1 As shown, each heat exchange tube 2 is a coil structure, and its opening communicating with the first pipe 4 is higher than its opening communicating with the second pipe 5. Based on this technical solution, the coolant in the second pipe 5 passes through each heat exchange tube 2 by overflow, reducing the flow rate and improving the effect of heat exchange condensation.

[0048] During the operation of the condensing tank provided by the utility model, cold water enters from the upper inlet of the second pipe 5, flows out from the upper outlet of the first pipe 4, and passes through each section of the heat exchange tube 2 for heat exchange condensation. The temperature of the coolant in each section of the heat exchange tube 2 is the incoming water temperature, so that each section of the heat exchange tube 2 can fully exchange heat and condense, thereby improving the overall heat exchange condensation effect.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
