Description

Technical Field

[0001] The present invention relates to the technical field of packed towers, and particularly to a packing support. Background Art

[0002] A packed tower is a mass transfer device with packing inside the tower as the contact component between gas and liquid phases. The packed tower belongs to a continuous contact type gas-liquid mass transfer device, and the two-phase composition changes continuously along the tower height. Under normal operating conditions, the gas phase is the continuous phase and the liquid phase is the dispersed phase. The packed tower is a commonly used separation device, with characteristics such as low pressure drop and large operating flexibility.

[0003] The reasonable design of the packing support plays an important role in ensuring the operating performance of the packed tower. Conventional designs use hump-shaped supports or grid supports added on the upper part of the steel beam. As the packed tower becomes larger, the steel beam becomes larger and the height of the tower vessel also increases continuously, increasing the investment cost. In addition, there are also defects such as uneven gas-liquid distribution and reduced mass transfer efficiency. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a packing support that can place regular packing or dumped packing, reduce the tower height, and reduce costs; is conducive to uniform gas-liquid distribution and improves mass transfer efficiency.

[0008] The support plate is a right-angled triangular plate, one of the right-angled sides is fixedly connected to the inner wall of the packed tower, and the bottom surface of the support ring is fixedly connected to the other right-angled side of the support plate.

[0022] The following further describes the specific embodiments of the present invention in conjunction with the drawings:

[0023] As Figures 1-4 shown, a kind of packing support includes an expanded metal honeycomb 1, a T-beam 2, a T-beam support 3, a support ring 4 and a support plate 5.

[0024] The support ring 4 is annular, and the side surface of the support ring 4 is welded to the inner wall 6 of the packed tower. The support plate 5 is a right-angled triangular plate. One right-angled side of the support plate 5 is welded to the inner wall 6 of the packed tower. The bottom surface of the support ring 4 is welded to the other right-angled side of the support plate 5. The support plate 5 plays a role in supporting the support ring 4.

[0025] There are two T-shaped beams 2. The support ring 4 is provided with 4 symmetrically arranged notches in pairs. The T-shaped beam support 3 is located at the bottom of the notch. The side surface of the T-shaped beam support 3 is welded to the inner wall 6 of the packed tower. The top surface of the T-shaped beam support 3 is welded to the bottom of the support ring 4.

[0026] The vertical beam of the T-shaped beam 2 is upward. The two ends of the cross beam of the T-shaped beam 2 are located in the notches. The upper surface of the cross beam of the T-shaped beam 2 is on the same plane as the upper surface of the support ring 4. There are holes on both the cross beam and the vertical beam of the T-shaped beam 2. The T-shaped beam 2 is welded to the T-shaped beam support 3, and the T-shaped beam support 3 supports the T-shaped beam 2.

[0027] The steel wire mesh packing nest 1 is placed on the plane formed by the upper surface of the cross beam of the T-shaped beam 2 and the upper surface of the support ring 4. The height of the steel wire mesh packing nest 1 is the same as the height of the vertical beam of the T-shaped beam 2. The size of each steel wire mesh packing nest 1 of the steel wire mesh packing nest 1 is determined according to the manhole, and the steel wire mesh packing nest 1 is made into a shape that fits the tower vessel at the tower wall. Regular packing or random packing can be placed on the upper part of the packing support.

[0028] As Figure 3 shown, the steel wire mesh packing nest 1 includes a steel wire mesh 7, a support member 9 and a tie rod 8. A plurality of steel wire meshes 7 and support members 9 are arranged alternately and are fixedly connected together by the tie rod 8 and bolts.

[0029] As Figure 4 shown, the steel wire mesh packing nest 2 includes a V-shaped steel wire mesh 10 and a tie rod 8. The V-shaped steel wire mesh 10 is evenly distributed with V-shaped bends. A plurality of V-shaped steel wire meshes 10 are fixedly connected together by the tie rod 8 and bolts.

[0030] The present invention makes full use of the height of the steel wire mesh packing nest 1 and the T-shaped beam 2 to reduce the tower height and thus reduce the cost. There are holes on the cross beam and the vertical beam of the T-shaped beam 2; reducing the gas-liquid phase resistance is beneficial to the uniform distribution of gas and liquid. The steel wire mesh packing nest 1 can play a role in the uniform distribution of gas and liquid, and at the same time also play a role in the mass transfer of the packing, improving the mass transfer efficiency.

[0031] The present invention can place regular packing or random packing, reduce the tower height, reduce the cost; is beneficial to the uniform distribution of gas and liquid, and improves the mass transfer efficiency.
