Description

Technical Field

[0001] The utility model relates to a distillation tower, in particular to a quick-detachable chemical distillation tower. Background Art

[0002] Distillation towers are very common in chemical plants and are mainly used to separate different components in a mixture. They achieve separation of substances by utilizing the difference in boiling points between different components. Common distillation towers are divided into plate towers and packed towers. Compared with packed towers, plate towers have the advantages of simple structure, low cost, large processing capacity and stable efficiency, so they are more widely used. Plate towers are stage contact equipment. Through multi-layer plate structures set at different heights, gas-liquid contact, mass transfer and heat transfer are carried out on the surface of the tower plate, thereby achieving separation of different components. The tower plate is the core component of the plate tower. The liquid phase flows into the liquid receiving tank of the lower tower plate through the downcomer. The height of the liquid phase on the lower tower plate increases to form a liquid seal. In order to ensure that the liquid phase has a certain height on the tower plate, an overflow weir is usually provided on one side of the tower plate, which can also have a buffering effect on the liquid phase.

[0003] Plate towers are divided into bubble type, sieve plate type, float valve type and jet type according to their plate types. Among them, the bubble cap structure is an early old-fashioned plate with high operating flexibility, not easy to leak, and low frequency of scaling or clogging, but its manufacturing and installation costs are high, and the pressure drop caused during operation is higher, which may lead to greater energy consumption and operating costs. It is rarely used in new tower applications. The sieve plate structure is also a structure that was used more in the early days. It has a simple structure. Circular sieve holes are directly opened on the plate according to the design requirements. As a gas phase channel, the gas phase directly passes through the sieve holes and contacts with the liquid on the plate. It has a simple structure, low cost, small pressure drop and high efficiency, but low operating flexibility and high requirements for process control. The float valve type and the jet type are new types of plates that are used more frequently at this stage. They have moderate cost, small pressure drop, high efficiency, large operating flexibility, outstanding comprehensive capabilities and rich types. For the jet plate, during the installation process, the corresponding jet box is usually fixed to the plate by welding, which makes subsequent maintenance and cleaning very inconvenient. To this end, we designed a quick-disassembly chemical distillation tower to solve the above problems. Utility Model Content

[0007] Preferably, the plurality of pressure strips are in a V-shaped frame structure with the opening facing downward, and a gap is left between any two adjacent pressure strips. The setting of the pressure strips, on the one hand, provides structural compression for the plurality of spray boxes arranged in a row, and on the other hand, the V-shaped frame structure design is adopted, and the pressure strips can provide a baffle effect for the droplets sprayed from the mesh structure, which helps to improve the gas-liquid separation effect.

In addition, combined with the bubble base structure, the downward path of the liquid phase is increased, further improving the distillation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1-Figure 8 The quick-disassembly chemical distillation tower shown in the figure comprises a tower body 100 and a plurality of spray trays 300 which are equidistantly arranged in sequence along the axial direction through a support frame 200, and any two upper and lower adjacent spray trays 300 are symmetrically distributed about the axial direction of the tower body 100, and the spray tray 300 comprises a base 310 and a spray assembly 320 mounted thereon, and the spray assembly 320 comprises a plurality of spray boxes 3210 distributed in a rectangular array and a plurality of pressure strips 3220 of a number matching the number of columns in the array, and bolts 3230 distributed in the vertical direction are penetrated and installed at both ends of the plurality of pressure strips 3220, and the base 310 comprises a tower plate 310, and a plurality of pressure strips 3220 are installed in the ... 110 and two handles 3140, a plurality of air lifting holes 3120 respectively matched with a plurality of injection boxes 3210 are provided on the tower plate 3110, and a plurality of air lifting holes 3120 in the same row are provided with a card slot 3130 on the outside, the two card slots 3130 are respectively welded to the front and rear of the top surface of the tower plate 3110, a plurality of preset holes 3150 for bolts 3230 to penetrate and install are provided on the two handles 3140, and both sides of the bottom of the injection box 3210 are provided with a card strip 3211 extending horizontally outward and matched with the card slot 3130, and a mesh structure 3212 is provided on the two side walls of the upper part of the injection box 3210.

[0022] Based on the above-mentioned structural setting, the quick-disassembly chemical distillation tower is composed of a tower body 100, a plurality of support frames 200 and a plurality of injection tower plates 300, wherein the plurality of support frames 200 are evenly distributed and welded in the tower body 100 along the axial direction of the tower body 100 at equal distances, and the plurality of injection tower plates 300 are respectively assembled on the plurality of support frames 200, and any two adjacent injection tower plates 300 that are distributed up and down are symmetrically distributed about the axis of the tower body 100. During the installation process, the plurality of injection boxes 3210 are distributed in a rectangular array and are respectively clamped in a plurality of mutually parallel clamps. The injection boxes 3210 are arranged in the slot 3130, and the clamping strips 3211 on both sides of the bottom of the injection box 3210 are slidably clamped in the clamping slot 3130. After the plurality of injection boxes 3210 in the same row are clamped in the clamping slot 3130, the plurality of injection boxes 3210 in the same row can be positioned by means of the clamping strips 3220 which are arranged in parallel above the clamping slot 3130 and are fixed between the two handles 3140 by bolts 3230. Specifically, during the working process, the liquid phase on the injection tower plate 300 is divided into two parts and goes down, and one part goes down from the gap at the bottom of the injection box 3210.

Specifically, one positioning liner 3240 is embedded in the top of one spray box 3210, and when the plurality of spray boxes 3210 in the same row are clamped in the clamping slot 3130, the plurality of spray boxes 3210 in the same row can be quickly positioned with the help of the positioning liners 3240, and finally both ends of the pressure strip 3220 are fixed to the two handles 3140 by bolts 3230.

[0026] Furthermore, the spray box 3210 is configured as a trumpet-shaped structure, and its top opening area is larger than its bottom opening area. Specifically, the spray box 3210 is configured as a trumpet-shaped structure with a larger top and a smaller bottom, so that the mesh structure 3212 is tilted downward, and the liquid droplets sprayed from the mesh structure 3212 will splash into the liquid phase on the tray 3110, further increasing the gas-liquid contact area, which helps to improve the gas-liquid separation effect.
