Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically a stainless steel condenser with a staged cooling mechanism. Background Technology

[0002] A disc-shaped stainless steel condenser is a type of indirect heat exchange equipment with a spiral winding or coiled tube bundle as its core. It is mainly used to transfer the heat of a high-temperature gaseous or steam medium to a cold fluid, causing it to condense into a liquid state, while simultaneously recovering heat energy or achieving temperature control.

[0003] In existing disc-shaped stainless steel condensers, the high-temperature medium flows along the disc-shaped tube bundle during use. The heat of the high-temperature medium is conducted to the shell side through the stainless steel tube wall, while the cold fluid flows in the opposite direction, flushing the coil. This allows the cold fluid to absorb heat and then be heated before being discharged.

[0004] However, existing disc-shaped stainless steel condensers have the following problems when in use: the flow state of the cold fluid inside the shell side of the condenser tends to be stable, and the cooling efficiency of the stainless steel condenser cannot be dynamically adjusted according to the flow rate of the high-temperature medium to ensure the temperature uniformity of the cooled hot fluid. Utility Model Content

[0005] The purpose of this invention is to provide a stainless steel condenser with a staged cooling mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel condenser with a staged cooling mechanism, characterized in that it comprises:

[0007] The annular shell allows the cold fluid inside to flow from bottom to top;

[0008] A spiral coil is located inside an annular shell, allowing the internal hot fluid to flow from top to bottom.

[0009] The central tube is coaxially set at the bottom of the annular shell. Multiple sets of exchange holes are opened circumferentially at equal intervals on the outer peripheral wall of the central tube, and the cold fluid inside the central tube can flow from top to bottom.

[0010] The shielding component is located inside the central tube. The shielding component can rotate around the axis of the central tube by a preset angle, thereby changing the communication state between the inside of the annular shell and the inside of the central tube.

[0011] Furthermore, the shielding assembly includes a central ring, an arc-shaped plate, and an end cap. There are multiple central rings, which are spaced apart from bottom to top along the axis of the central tube. There are multiple arc-shaped plates, which are equally spaced around the axis of the central ring and are fixedly connected to the central rings. The end cap is located at the upper end of the arc-shaped plate and can rotate around its axis by a preset angle so that the arc-shaped plate shields the exchange hole or makes the arc-shaped plate and the exchange hole misaligned.

[0012] Furthermore, the end cap is threadedly connected to the upper part of the annular housing.

[0013] Furthermore, a grip handle is provided on the outside of the end cap.

[0014] Furthermore, the annular housing is provided with a first stop and a second stop at intervals on its outer circumference, both of which can abut against the grip handle.

[0015] Furthermore, the end cap has a first liquid inlet hole at its center, and the annular shell has a first liquid outlet hole at its bottom center.

[0016] Furthermore, a second liquid inlet is provided at the lower part of the annular shell, and a second liquid outlet is provided at the upper part of the annular shell.

[0017] Compared with the prior art, the present invention provides a stainless steel condenser with a staged cooling mechanism, which has the following beneficial effects:

[0018] This stainless steel condenser with a staged cooling mechanism is equipped with a shielding component. When the inlet flow rate of the spiral coil increases, the rotation of the shielding component allows the cold fluid inside the central tube to enter the annular shell, thereby accelerating the heat exchange between the cold fluid inside the annular shell and the cold fluid inside the central tube. This facilitates a rapid reduction in the temperature of the cold fluid inside the annular shell. Furthermore, the merging of the cold fluid inside the annular shell and the cold fluid inside the central tube creates a more turbulent flow state within the annular shell. This helps to disrupt the temperature boundary layer outside the spiral coil, resulting in higher heat exchange efficiency between the hot fluid inside the spiral coil and the cold fluid outside, thus ensuring the temperature uniformity of the cooled hot fluid.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0032] Please see Figures 1-7A stainless steel condenser with a staged cooling mechanism includes an annular shell 100, a spiral coil 200, a central tube 300, and a shielding assembly 400. The cold fluid inside the annular shell 100 can flow from bottom to top. The spiral coil 200 is located inside the annular shell 100, and the hot fluid inside the spiral coil 200 can flow from top to bottom. The central tube 300 is coaxially arranged at the bottom of the annular shell 100. Multiple sets of exchange holes 310 are equally spaced on the outer peripheral wall of the central tube 300, and the cold fluid inside the central tube 300 can flow from top to bottom. The shielding assembly 400 is located inside the central tube 300 and can rotate around the axis of the central tube 300 by a preset angle, thereby changing the communication state between the inside of the annular shell 100 and the inside of the central tube 300.

[0033] The end cap 430 has a first liquid inlet hole 431 at its center, the annular housing 100 has a first liquid outlet hole 432 at its bottom center, the annular housing 100 has a second liquid inlet hole 110 at its lower part, and the annular housing 100 has a second liquid outlet hole 120 at its upper part.

[0034] In the initial state, the shielding component 400 shields the exchange port 310. At this time, the cold fluid inside the annular housing 100 and the cold fluid inside the central tube 300 are independent of each other. The cold fluid inside the annular housing 100 enters through the second inlet port 110 and exits through the second outlet port 120. The cold fluid inside the central tube 300 enters through the first inlet port 431 and exits through the first outlet port 432. Since the first inlet port 431 is located at the lower part of the annular housing 100 and the second inlet port 110 is located at the upper part of the annular housing 100, there is a large temperature difference between the cold fluid inside the central tube 300 and the cold fluid inside the annular housing 100 along the flow direction of the cold fluid. Therefore, the temperature change of the cold fluid inside the annular housing 100 along its flow direction can be minimized through heat transfer, thereby improving the temperature uniformity of the hot fluid discharged from the outlet of the spiral coil 200.

[0035] When the inlet flow rate of the spiral coil 200 increases, in order to ensure the temperature uniformity of the hot fluid discharged from the outlet of the spiral coil 200, the operator rotates the shielding component 400 around the axis of the central tube 300 by a preset angle, so that the interior of the annular shell 100 and the interior of the central tube 300 are interconnected. At this time, the cold fluid inside the central tube 300 enters the interior of the annular shell 100 and merges with the cold fluid inside the annular shell 100, so that the heat exchange rate between the cold fluid inside the annular shell 100 and the cold fluid inside the central tube 300 is faster, so as to quickly reduce the temperature of the cold fluid inside the annular shell 100. In addition, the merging of the cold fluid inside the annular shell 100 and the cold fluid inside the central tube 300 makes the flow state of the cold fluid inside the annular shell 100 more turbulent, which helps to break the temperature boundary layer outside the spiral coil 200, making the heat exchange efficiency between the hot fluid inside the spiral coil 200 and the cold fluid outside the spiral coil 200 higher, thereby ensuring the temperature uniformity of the cooled hot fluid.

[0036] In a further embodiment, the shielding assembly 400 includes a central ring 410, an arc-shaped plate 420, and an end cap 430. There are multiple central rings 410, which are spaced apart from bottom to top along the axis of the central tube 300. There are multiple arc-shaped plates 420, which are equally spaced around the axis of the central rings 410 and are fixedly connected to the central rings 410. The end cap 430 is disposed at the upper end of the arc-shaped plate 420 and can rotate around its axis by a preset angle so that the arc-shaped plate 420 shields the exchange hole 310 or makes the arc-shaped plate 420 and the exchange hole 310 misaligned.

[0037] In the initial state, the arc plate 420 blocks the exchange hole 310, so the cold fluid inside the annular shell 100 and the cold fluid inside the central tube 300 are independent of each other.

[0038] When the shielding component 400 needs to rotate around the axis of the central tube 300, the operator rotates the end cap 430 by a preset angle so that the arc plate 420 no longer blocks the exchange hole 310. At this time, the cold fluid inside the central tube 300 can enter the annular housing 100 through the exchange hole 310, so that the cold fluid inside the central tube 300 and the cold fluid inside the annular housing 100 can mix and merge with each other.

[0039] In a further embodiment, the end cap 430 is threaded onto the upper part of the annular housing 100.

[0040] This arrangement is to facilitate the connection of the end cap 430 to the annular housing 100.

[0041] In a further embodiment, a grip handle 440 is provided on the outside of the end cap 430.

[0042] This design is intended to facilitate the rotation of the end cap 430 by the operator holding the handle 440.

[0043] In a further embodiment, the annular housing 100 is provided with a first stop bar 450 and a second stop bar 460 at intervals on its outer circumference, both of which can abut against the grip handle 440.

[0044] The first stop 450 and the second stop 460 are set to limit the rotation angle of the end cover 430, so as to facilitate the operation of the staff and prevent the end cover 430 from rotating too much or too little.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
