By means of the structure, the novel combined guide float valve tray comprises the guide fixed valves in a proper ratio, the pressure drop of the tray body is reduced, processing capability is improved, the guide fixed valves are capable of well eliminating liquid level gradients and liquid stagnation areas on the tray body for various different liquid loads through proper arrangement due to the fact that the guide fixed valves have large driving force, and thus the efficiency of the tray body is improved; due to the fact that the pressure drop of the guide fixed valves is small, the gas speed of valve holes is high, the function of a bubbling accelerator is achieve, liquid is made to start bubbling immediately once entering an open hole area of the tray body, the whole tray body is triggered to completely enter a bubbling state, inactive areas on the tray body are eliminated, liquid leakage is reduced, and the operation performance of the tray body is enlarged.
Description
Technical field
The present invention relates to technical field of chemical, specifically refer to a kind of novel Combined Lead Floating Valve Tray.
Background technology
Plate column is important gas-liquid mass transfer (contact) equipment, extensive use in chemical industry, oil refining and petrochemical industry.The kind of column plate is a lot, industrial commonly used be sieve tray, float valve type column plate and solid valve column plate etc.Sieve tray is simple in structure, and cost is lower, but operating flexibility is less.There is floating member on float valve type column plate, can automatically regulate within the specific limits gas phase channel, there is larger operating flexibility.In float valve type column plate, float valve is circular F1 type (or claiming the V1 type) valve plate, once in industrial extensive use.Along with the continuous progress of tower technology, find that there is obvious shortcoming in F1 type valve plate, mainly contain: the liquid dispersion on column plate is larger, and gradient of liquid level is larger, has liquid stagnation region etc. on column plate, and these all make plate efficiency reduce.91215110.2) and the Combined Lead Floating Valve Tray (patent No.: the float valve tower version such as 96229716.X) for overcoming the above-mentioned shortcoming of F1 type valve plate, China scientific worker has successively developed the guide float valve tray (patent No.:.Wherein, contain rectangle guide float-valve and trapezoidal directed float valve on this Combined Lead Floating Valve Tray, the suitable proportioning and arranging by the two, for different liquid loads, all can eliminate gradient of liquid level and liquid stagnation region on column plate, has good operating characteristics.
Experimental studies have found that, on Combined Lead Floating Valve Tray, because the liquid just entered on column plate is clear liquid basically, impact with larger liquid layer static pressure and larger surface tension of liquid, the liquid layer resistance is larger, gas be difficult to by, form disactivation district (being non-bubbling area) to a certain degree at the liquid-inlet end, and cause liquid obviously to leak, reduced plate efficiency.For reducing the disactivation district of liquid-inlet end, need to increase valve opening gas speed, thereby increased the gas phase load as the operation lower limit, reduced the operating flexibility of tower.
Gu on the valve column plate,, without floating member, valve block is directly gone out by valve hole plate, formed the sideshake of valve opening and valve block, for gas phase, flow out, and the liquid on column plate carries out the mass transport process between gas-liquid.Gu the valve column plate is compared with valve plate, plate pressure drop is less, and disposal ability is larger, and processing and the maintenance cost of column plate are lower.Thereby, in recent years developmental research and the commercial Application of solid valve column plate have been subject to attention.Gu it is multiple that the kind of valve column plate has, industrial commonly used have rectangle guide fixed valve, trapezoidal guide fixed valve and the Combined guiding fixed valve tower plate (patent No.: CN202036813U) etc.As shown in Figure 1, trapezoidal guide fixed valve as shown in Figure 2 for the rectangle guide fixed valve.On Combined guiding fixed valve tower plate, the rectangle guide fixed valve that contains suitable proportioning and trapezoidal guide fixed valve, to reduce gradient of liquid level and liquid stagnation region.For the solid valve of above-mentioned bar shaped, two ends are provided with the valve leg of tilting, and the incline direction of front and back valve leg is contrary, from front and back valve leg effluent air, to the thrust of liquid is all or part of, cancels out each other, and has reduced the effective push of gas to liquid.Simultaneously, because there is the valve leg in solid valve two ends, when the solid valve of punching, the valve leg at two ends produces drawing-resistant function, has restricted the deployed height of valve block, has caused the sideshake area of solid valve less than normal, has affected the operating characteristics of solid valve column plate.
