Description

Technical Field

[0001] The present application relates to the field of petrochemical storage tank technology, and in particular to an inner floating plate storage tank system. Background Art

[0002] According to the technical specifications for the engineering of assembled inner floating plates for petrochemical storage tanks, the inlet flow rate of the inner floating plate storage tank shall not be greater than 1m / s. To meet the requirements, for inlets with a flow rate greater than 1m / s, a diffusion pipe is usually set up. An inner extension pipe with a flow rate no less than 1 level larger than the inlet is set up on the inside of the inlet to reduce the inlet flow rate to below 1m / s in the pipe, and then the material flows into the tank as evenly as possible through the diffusion holes on the diffusion pipe. The diffusion pipe plays a role in reducing the flow rate and expanding the distribution range of the material.

[0003] Usually, a diffuser is a structure in which the material inlet and the internal diffuser are connected as a whole through a reducer or a reducer. When the diffuser is a structure in which the material inlet and the internal diffuser are connected as a whole through a reducer or a reducer, due to the long inner extension tube, the installation error of the internal bracket and the change of the liquid level in the tank will lead to irregular deformation of the tank bottom and settlement of the tank bottom plate to varying degrees. When the bracket cannot support the inner extension tube, the gravity or deformation on the inner extension tube is not coordinated, resulting in a large additional bending moment at the inlet tube on the tank wall, which is not conducive to the safety of the tank wall. In addition, when inspecting and repairing the tank, if the inner diffuser needs to be replaced, the inlet and the diffuser need to be cut and separated, which will generate sparks, is not conducive to operation in the confined space inside the tank, and there are major operational safety hazards.

DETAILED DESCRIPTION

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. The specific structural and functional details disclosed herein are only used to describe the exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments described herein.

[0029] like Figure 1 As shown, Figure 1 The structural schematic diagram of the internal floating tank system provided in the embodiment of the present application is an internal floating tank system, wherein the internal floating tank system comprises a tank body 100, a guide member 200, a first support member 300 and a diffuser 400, wherein:

[0030] The tank body 100 is provided with an operation cavity. For the convenience of arrangement, the bottom of the tank body 100 can be made flat, so as to facilitate the positioning and fixing of the tank body 100 as a whole and ensure reliable operation.

[0031] The guide member 200 is arranged on the tank body 100, and a through cavity is arranged in the guide member 200, and one end of the guide member 200 passes through the tank body 100 and extends into the working cavity, so as to guide the material into the working cavity. The guide member 200 is arranged on the tank body 100, and one end of the guide member 200 is used to pass the material, and the other end is used to guide the material to flow into the tank body 100, so as to facilitate repeated operation connection operations.

[0032] like Figure 1 As shown, a plurality of first supporting members 300 are provided and are respectively arranged in the working cavity. A supporting space extending in a vertical direction is provided on the first supporting member 300 .

[0033] It should be noted that the first support members 300 are respectively fixed to the bottom of the tank body 100 . When the bottom of the tank body 100 undergoes a certain degree of relative settlement, the first support members 300 also undergo relative settlement displacement synchronously.

[0034] The diffuser pipe 400 is arranged in the working cavity, and a diffusion cavity is provided in the diffuser pipe 400. One end of the diffuser pipe 400 is movably connected to one end of the guide member 200 extending into the tank body 100. The first support member 300 supports the diffuser pipe 400 respectively. The middle part of the diffuser pipe 400 passes through the supporting space and can move in the supporting space along the vertical direction.

[0035] In the radial direction, the cross-sectional area of ​​the diffuser 400 is larger than the cross-sectional area of ​​the guide member 200, so that the flow velocity of the material is reduced to meet the set requirements.

[0036] like Figure 1 As shown, the diffuser 400 is movably connected to the guide member 200, and relative displacement can occur between the diffuser 400 and the guide member 200, thereby avoiding deformation of the tank body 100 caused by synchronous displacement of the diffuser 400 and the guide member 200, and the diffuser 400 as a whole can also move in the vertical direction within the supporting space. Since the first support member 300 is supported at the lower part of the diffuser 400, the supporting space extends in the vertical direction accordingly. When the first support member 300 undergoes relative displacement, the diffuser 400 can undergo relative displacement relative to the first support member 300 within the supporting space, thereby avoiding the displacement of the first support member 300 directly driving the synchronous displacement of the diffuser 400, thereby improving the relative stability under complex working conditions.

[0037] In an optional embodiment, the working principle of the internal floating tank system in the present application is: the internal floating tank system includes a tank body 100, a working cavity is provided in the tank body 100, a guide member 200 is provided on the tank body 100, a through cavity is provided in the guide member 200, and one end of the guide member 200 passes through the tank body 100 and extends into the working cavity to guide materials into the working cavity, a plurality of first support members 300 are provided in the working cavity, a supporting space extending in a vertical direction is provided on the first support member 300, a diffusion pipe 400 is provided in the working cavity, and a diffusion cavity is provided in the diffusion pipe 400, one end of the diffusion pipe 400 is movably connected to one end of the guide member 200 extending into the tank body 100, the first support member 300 supports the diffusion pipe 400 respectively, the middle part of the diffusion pipe 400 passes through the supporting space, and can be vertically arranged in the working cavity. The diffuser 400 moves in the supporting space. During actual operation, the material enters the discharging cavity of the diffuser 400 through the through cavity in the guide 200, and enters the working space of the tank body 100 through the diffuser 400. Through the movable connection between one end of the diffuser 400 and the guide 200, the middle part of the diffuser 400 is supported and fixed by multiple first support members 300. The diffuser 400 can move relative to the first support member 300 in the supporting space, eliminating the installation errors of the first support member 300 and the diffuser 400. When the liquid level in the tank changes, causing irregular deformation of the tank bottom and settlement of the tank bottom plate, the relative movement of the diffuser 400 and the first support member 300 eliminates the large additional bending moment formed at the inlet pipe on the tank wall, so that the deformation of the bottom of the tank body 100 is not associated with the tank wall, avoiding the generation of additional force, and effectively improving the safety of operation.

[0038] like Figure 3 As shown, Figure 3 A side view of the first support member 300 provided in an embodiment of the present application, in an optional embodiment, the first support member 300 includes a horizontally arranged transverse portion 301 and two vertically arranged vertical portions 302, the transverse portion 301 is fixedly connected between the spaced vertical portions 302, and forms the supporting space between the vertical portions 302, and the distance between the two vertical portions 302 is the same as the outer diameter of the diffuser 400.

[0039] The mutually perpendicular transverse portion 301 and the vertical portion 302 form a supporting space, and the transverse portion 301 and the vertical portion 302 can be fixed by welding to maintain the stable supporting effect of the transverse portion 301 and the restraining effect of the two vertical portions 302 on the diffuser 400, so as to keep the diffuser 400 moving in a relatively stable supporting space.

[0040] like Figure 2 As shown, Figure 2This is a side view of the annular member 402 provided in an embodiment of the present application. In an optional embodiment, the diffuser 400 is detachably provided with an annular member 402 at the end near the guide member 200. The annular member 402 is sleeved on the guide member 200, and a first gap 403 is provided between the annular member 402 and the guide member 200.

[0041] The annular member 402 is detachably arranged at the end of the diffuser 400, and the diffuser 400 is positioned by the annular member 402. After the diffuser 400 is arranged, a first gap 403 is formed between the annular member 402 and the guide member 200, so that the guide member 200 and the diffuser 400 maintain a relative position within a set range. In addition, the diffuser 400 can be relatively displaced with the guide member 200 through the preset first gap 403, thereby limiting the deformation transferred between the diffuser 400 and the guide member 200, thereby improving the overall reliability.

[0042] like Figure 2 As shown, in order to maintain the convenience of transfer of the ring member 402, the ring member 402 may not be arranged as two detachable semicircular members.

[0043] like Figure 1 As shown, in an optional embodiment, a plurality of discharge holes 401 are evenly arranged on the diffuser pipe 400, and the discharge holes 401 are arranged below the horizontal axis of the diffuser pipe 400, so that the material in the discharge cavity passes through the discharge holes 401 and enters the working cavity.

[0044] The material in the diffuser 400 is diffused through a plurality of diffusion holes 401, and the material in the diffusion cavity passes through the diffusion holes 401 into the working cavity, and the material is guided by the position of the diffusion holes 401, and the diffusion holes 401 are arranged below the horizontal axis of the diffuser 400, so that the material can pass through the plurality of diffusion holes 401 normally and evenly by gravity, and the material is prevented from being ejected upward to impact the inner floating plate.

[0045] In an optional embodiment, the sum of the flow rates of the emission holes 401 is not less than the flow rate of the diffusion tube 400, so as to improve the smoothness of the material passing through the emission holes 401 and avoid the occurrence of a jamming phenomenon.

[0046] like Figure 4 As shown, Figure 4 A side view of a second support member 501 provided in an embodiment of the present application. In an optional embodiment, the inner floating tank system further includes a second support member 501, which is disposed in the tank body 100 and fixedly connected under the diffuser 400, and the overlapping section of the diffuser 400 and the guide member 200 and the second support member 501 are arranged in a longitudinal position at the foundation ring beam 701.

[0047] The second support member 501 is supported under the diffuser 400 and fixedly connects the diffuser 400 and the tank body 100, thereby improving the reliability of the relative position of the diffuser 400, and the second support member 501 is arranged at the relative position of the foundation ring beam 701. The foundation ring beam 701 serves as an installation basis and maintains a reliable relative position relationship. The foundation ring beam 701 and the second support member 501 are at the same longitudinal position. The second support member 501 and the foundation ring beam 701 are synchronously settled, and the overlapping section of the diffuser 400 and the guide member 200 is also at the same longitudinal position. The second support member 501 is also used to keep the diffuser 400 at this location to settle synchronously, thereby avoiding the height difference caused by settlement, avoiding the bending moment stress between the diffuser 400 and the guide member 200, and improving the overall reliability.

[0048] like Figure 1 , Figure 4 As shown, in an optional embodiment, a supporting block 502 is provided between the outer wall of the guide member 200 and the inner wall of the diffuser 400, and the supporting block 502 and the second support member 501 are respectively located on both sides of the same position on the diffuser 400, and a plurality of the supporting blocks 502 are arranged at intervals.

[0049] The relative position relationship between the guide member 200 and the diffuser 400 is maintained by multiple supporting blocks 502, and the multiple supporting blocks 502 are pressed by the guide member 200 and the diffuser 400. By controlling the thickness of the supporting blocks 502, the guide member 200 and the diffuser 400 can be kept coaxially arranged, and the uniformity of each first gap 403 can be maintained, thereby improving the operation stability.

[0050] The supporting block 502 and the second supporting member 501 are respectively located on both sides of the same position on the diffuser 400, further making the overlapping section of the diffuser 400 and the guide member 200, the supporting block 502 and the second supporting member 501 arranged in the longitudinal position of the basic ring beam 701, keeping the basic ring beam 701 supporting the second supporting member 501 and the supporting block 502 at the same position, thereby improving stability.

[0053] The detachable connection between the first guide part 201 and the second guide part 202 allows the second guide part 202 to be flexibly disassembled for operation while keeping the first guide part 201 tightly and stably connected to the tank body 100, avoiding cutting and other operations directly inside the tank body 100, thereby improving the convenience and safety of operation.

[0054] like Figure 1 As shown, in an optional embodiment, a plurality of auxiliary holes 203 are provided on the side wall of the guide member 200 , so that the material enters the discharging cavity from the end of the guide member 200 and the auxiliary holes 203 at the same time.

[0055] After the material enters the guide 200, it is discharged into the diffuser 400 from the end of the guide 200, and at the same time, it enters the diffuser 400 through multiple auxiliary holes 203, further improving the stability and uniformity of material movement and avoiding unidirectional impact of the material.

[0056] like Figure 1 As shown, in an optional embodiment, a removable cover 601 is provided at one end of the diffuser 400 away from the diffuser 400, and an exhaust hole 602 is provided on the cover 601.
