Abstract
Description
本发明涉及锯齿状塔板，它是一种安装在化工塔设备中的塔板，属于化工设备领域。The invention relates to a sawtooth tray, which is a tray installed in a chemical tower equipment and belongs to the field of chemical equipment.
塔设备是石油和化工领域常用的一种气液、液液接触传质设备，主要包括板式踏板和填料式塔板。高效填料踏板效果高，并且生产能力大，但是由于造价高，而且不适合于高压和易结焦的场合。相对于填料塔，普通板式塔由于其造价低廉，在常压和高压工况中国得到广泛的应用。Tower equipment is a gas-liquid, liquid-liquid contact mass transfer equipment commonly used in petroleum and chemical industry, mainly including plate pedals and packed trays. The high-efficiency packed pedal has a high effect and a large production capacity, but it is not suitable for high pressure and easy coking because of its high cost. Compared with packed towers, ordinary slab towers are widely used in China under normal pressure and high pressure conditions due to their low cost.
但是在大液量吸收、精馏等工况中由于液气比非常大，例如水水洗脱碳的液气摩尔比高达100以上。对于此类工况，普通的板式塔往往也能发挥优势：塔板上的受液区往往占据了很大塔截面积，造成塔的处理能力低。如采用填料塔，为了能通过大液量，塔径会设计得很大，气体以极低的气速通过填料层，传质小效率低，用水量大，能耗高。However, in the case of large liquid absorption, rectification and the like, since the liquid-gas ratio is very large, for example, the liquid-gas molar ratio of the water-eluting carbon is as high as 100 or more. For such working conditions, ordinary plate towers often have an advantage: the liquid receiving area on the tray often occupies a large tower cross-sectional area, resulting in a low processing capacity of the tower. If a packed tower is used, the tower diameter will be designed to be large in order to pass the large liquid volume, and the gas passes through the packing layer at a very low gas velocity, the mass transfer is small, the efficiency is low, the water consumption is large, and the energy consumption is high.
固定浮阀塔板具有生产能力大，塔板效率高，加工及维护成本低等优点，在石油化工领域有着广泛的应用。目前，工业上的固定浮阀塔板主要为圆形固定浮阀和条形固定浮阀两种，这两种固定浮阀主要有以下特征：直接在塔板平面上冲出圆形和条形突起，将其边缘开口作为气相通道，阀片前后各有一条阀腿与塔板相连接，来支撑阀片，阀腿与塔板平面的夹角约为90度。对于圆阀，气体出口为一圆弧，从出口前半部喷出的气体对板上液流有一定的推动作用，而从出口后半部喷出的液体对板上液流有阻止作用，前后两种作用相互削弱。对于条形固定浮阀，气体喷出方向与液流方向垂直，不但没有推液作用，而且，相邻的两个阀片喷出的气体方向相对，造成严重的对喷现象，容易引起返混和雾沫夹带，削弱塔板的传质功能，降低塔板效率。舌形塔板上设有倾斜的舌孔，使喷出气流的方向接近水平，因而雾沫夹带大为减少，同时气流对液流有推进作用，因此气液流通过能力均较高，气体通量大，液面落差小，无返混现象，能够降低塔板压降。舌形塔板具有塔板效率高，板上液层较薄，塔板压力降小的优点。但是舌形塔板对负荷波动的适应能力差，操作弹性小，严重的气相夹带现象可能导致板效率下降，同时由于塔板上液层太薄，液体停留时间短，气液接触不充分，板效率显著降低。The fixed valve tray has the advantages of large production capacity, high efficiency of the tray, low processing and maintenance cost, and has wide application in the petrochemical industry. At present, the fixed valve trays in the industry are mainly round fixed float valves and strip fixed float valves. The two fixed float valves mainly have the following characteristics: directly punching round and strip on the plane of the tray The protrusion has its edge opening as a gas phase passage, and a valve leg is connected to the tray before and after the valve piece to support the valve piece, and the angle between the valve leg and the plane of the tray is about 90 degrees. For the round valve, the gas outlet is a circular arc, and the gas ejected from the front half of the outlet has a certain pushing effect on the liquid flow on the plate, and the liquid ejected from the rear half of the outlet has a blocking effect on the liquid flow on the plate, before and after The two roles weaken each other. For the strip-shaped fixed float valve, the gas ejection direction is perpendicular to the liquid flow direction, and not only does not have a liquid pushing effect, but also the gas directions ejected by the adjacent two valve sheets are opposite, causing a serious collision phenomenon, which easily causes back mixing. Entrainment of mist, weakening the mass transfer function of the tray and reducing the efficiency of the tray. The tongue-shaped tray has inclined tongue holes, so that the direction of the jet airflow is close to the horizontal, so the mist entrainment is greatly reduced, and the airflow has a propelling effect on the liquid flow, so the gas-liquid flow passing ability is high, and the gas passage is high. The amount is large, the liquid level drop is small, and there is no back mixing phenomenon, which can reduce the pressure drop of the tray. The tongue-shaped tray has the advantages of high efficiency of the tray, thinner liquid layer on the plate, and small pressure drop of the tray. However, the tongue-shaped tray has poor adaptability to load fluctuations, and the operation flexibility is small. The serious gas phase entrainment may cause the plate efficiency to decrease. At the same time, because the liquid layer on the tray is too thin, the liquid residence time is short, and the gas-liquid contact is insufficient. The efficiency is significantly reduced.
塔板和填料复合主要有溢流式塔板复合填料和穿流式塔板复合填料，由于穿流式塔板结构简单、易于填料复合，是最为理想的塔板填料复合形式。但现有穿流塔板复合填料，由于规整填料的液泛使复合塔板的弹性和负荷能力受到限制。The tray and filler composite mainly consists of overflow tray composite filler and through-flow tray composite filler. Because of the simple structure of the flow-through tray and easy packing and compounding, it is the most ideal composite form of tray filler. However, the existing through-flow tray composite filler limits the flexibility and load capacity of the composite tray due to the flooding of the structured packing.
发明人经过检索发现专利号200510094252.6公开了菱形固定浮阀。但是由于两个阀腿的存在，对喷和返混现象不能完全解决。在石油化工、石油炼制、化工、轻工、环保、医药及原子能等工业部门，塔板和填料广泛应用于蒸馏、吸收、萃取、吸收、洗涤、冷却等化工单元过程。填料具有分离效率高、压降小、处理能力大等优点，但成本较大，操作弹性小，对配套塔内件要求高；塔板操作弹性大、抗堵塞、成本低、分离效率相对较大，但压降将较大，处理能力较低。塔板按有无降液管可分为溢流式塔板和穿流式塔板，相比之下，现有穿流式 塔板结构简单，塔内空间利用率高，成本低，处理能力大，但汽液接触时间短，传质效率低，操作弹性小。理想的塔内件应同时具有低压降、高效率、大操作弹性、抗堵塞、低成本、大处理能力和塔内空间利用率高的特性。将塔板和填料复合是实现理想塔内件的有效途径之一。纤维束填料是一种新近开发的气液相均为连续相的高表面积挂网式柔性填料，液泛气速高达8m/s以上，传质效率高，压降仅为普通规整填料的1/2-1/3。The inventors found through the search that the patent number 200510094252.6 discloses a diamond-shaped fixed float valve. However, due to the presence of the two valve legs, the spray and back mixing phenomena cannot be completely solved. In the petrochemical, petroleum refining, chemical, light industry, environmental protection, pharmaceutical and atomic energy industries, trays and fillers are widely used in chemical unit processes such as distillation, absorption, extraction, absorption, washing, and cooling. The packing has the advantages of high separation efficiency, small pressure drop and large processing capacity, but the cost is large, the operation flexibility is small, and the requirements for the internal parts of the supporting tower are high; the operation of the tray is large, anti-blocking, low cost and relatively high separation efficiency. However, the pressure drop will be larger and the processing capacity will be lower. The tray can be divided into an overflow tray and a through-flow tray according to the presence or absence of a downcomer. In contrast, the existing through-flow type The tray structure is simple, the space utilization in the tower is high, the cost is low, and the processing capacity is large, but the vapor-liquid contact time is short, the mass transfer efficiency is low, and the operation flexibility is small. The ideal inner part of the tower should have the characteristics of low pressure drop, high efficiency, large operational flexibility, anti-blocking, low cost, large processing capacity and high space utilization in the tower. Combining trays and packing is one of the effective ways to achieve the ideal internals. Fiber bundle filler is a newly developed high surface area net-type flexible filler with gas phase and continuous phase. The liquid gas velocity is up to 8m/s, the mass transfer efficiency is high, and the pressure drop is only 1/1 of the normal structured packing. 2-1/3.

The invention can make the gas pass through the tray in the form of a horizontal blown liquid film, and the pressure drop of the tray is small compared with the conventional tray without the need to overcome the static pressure of the liquid layer. However, the present invention needs to install the caps one by one, the installation process is vast, each cap needs to be installed vertically, the installation requirements are high, and the regular maintenance cost of the caps in the tower is high.

Part of the gas is empty between the fan plate and the bottom at the bottom of the tray body The gap rises above the tray body, and part of the gas rises from the gap of the valve plate on the inclined plate to the upper side of the tray body when flowing through the inclined plate, so that the gas is divided into several lines and enters the gas-liquid mass transfer tower. At the top, the flow path of the gas in the gas-liquid mass transfer tower selects different paths according to the water content in the lift gas, and also allows the water in the gas to be collected and dripped into the gas-liquid mass transfer tower, and the gas is filled. The top of the tray body overflows down to the valve plate, passes through the gap of the valve plate and rises above the tray body. The flow of gas in the gas-liquid mass transfer tower is moderate, and the liquid can be more fully and slowly. Contact with the ground to prolong the contact mass transfer time.
液体从气液传质塔的顶部喷淋下来后，滴落到塔板本体的上表面，从扇板与塔板本体的底部的空隙中流到塔板本体的下方，该空隙使得液体呈布状流下去，增加液体与气体的直接接触面积和接触的交织程度；当液体的喷淋的速度很快时，液体可能会浸没到阀片处，从阀片与倾斜板之间的空隙中流下去。After the liquid is sprayed from the top of the gas-liquid mass transfer tower, it drops onto the upper surface of the tray body, flows from the gap between the fan plate and the bottom of the tray body to the lower side of the tray body, and the gap makes the liquid cloth-like. Flowing down increases the direct contact area of the liquid with the gas and the degree of interweaving of the contact; when the spray speed of the liquid is fast, the liquid may be submerged to the valve plate and flow from the gap between the valve plate and the inclined plate.

所述顶部4设置有自然下垂的引流绳7。引流绳7能将顶部4的气体中的水蒸气汇集形成水珠，并通过引流绳7滴落下去。The top 4 is provided with a naturally sagted drainage cord 7. The drain cord 7 can collect the water vapor in the gas of the top 4 to form a water droplet, and drip through the drain cord 7.
所述引流绳7的直径从上向下逐渐减小，使得引流绳7表面的水珠汇聚，引流绳7表面设有螺旋的纹路，螺旋的纹路使得水珠形成水流，并将引流绳7四周的水珠形成一条水流，然后导流到引流绳7的底部3，将水流滴落下去。The diameter of the drainage cord 7 gradually decreases from the top to the bottom, so that the water droplets on the surface of the drainage cord 7 converge, and the surface of the drainage cord 7 is provided with a spiral pattern, and the spiral pattern causes the water droplets to form a water flow, and the drainage cord 7 is surrounded. The water droplets form a stream of water which is then diverted to the
所述阀片6中间拱起部分的下表面设置有波浪形状的褶皱。波浪形状的褶皱增加气体与阀片6的接触时间，使得气体中的热能能更充分地传递给阀片6，提高传质效率。The lower surface of the intermediate arched portion of the
