Abstract

The utility model relates to a gas-liquid contact controller which is improved from mass transferring and heat transferring equipment, particularly improved from the critical component of tongue sheet valve of equipment which completes the mass transferring and heat transferring process through gas and liquid contact. The specific concept is that an ordinary gas hole is improved into a venturi gas rising hole on the plywood of tower type equipment, a plate type valve sheet is improved into a spherical valve body, and the plate type valve sheet is fixed above the venturi gas rising hole by utilizing a limiting frame for the spherical valve body. By the utilization of the optional balance property of the spherical valve body, the defects of the previous tongue sheet valves that the tongue sheet valves are easy to clamp and die, the gas resistance is big, the gas stream is low, and the sealing performance is bad.

Description

The gas-liquid contactor controller

The utility model is a kind of by auxiliary equipment in gas-liquid contact realization mass transfer, the heat-transfer equipment, specifically a kind of throughput self-checking device.

Contacting to realize mass transfer, conduct heat to be the frequent application technology means of chemical industry and other industry by gas-liquid, for example all is to design according to such technology theory in the equipment such as rectifying column, absorption tower, conditioning Tower, cooling tower.The multilayer level course plank frames that adopt all evenly are provided with several valve opening passages more in the tower on each laminate.The tongue plate type float valve is set on the valve opening passage.So be referred to as valve tower or floating-tongue type jet tray sometimes again.This float valve or floating tongue are crossed the flow velocity difference of laminate valve opening to produce different buoyancy in order to regulate the opening degree of clack valve by air communication, and, connect operating characteristic and the comparatively ideal exchange efficiency of separating thereby obtain the control gas-liquid according to the automatic percent openings of regulating the tower inner platings of the difference of airflow loads.Yet be that monolateral fixing tongue piece formula float valve or free lifting valve block formula float valve in use all are prone to stuck or by the phenomenon of air-flow stripping, thereby the integrated operation characteristic is obviously degenerated.In addition, leave certain interval between flat valve block and the tower inner plating, cause poorly sealedly, when low speed flow, can occur the leakage of tower laminate especially and make the laminate decrease in efficiency.Particularly the edge of valve block mostly is sharp edge, though this is useful to gas, liquid less turbulence increase raising mass-transfer efficiency, can produce bigger gas-flow resistance simultaneously, so the improvement with float valve has been become one of key of this kind equipment of improvement.

Goal of the invention of the present utility model promptly is the improvement to float valve in this kind equipment, proposes a kind of new device of gas-liquid contactor controller, to overcome the shortcoming of existing float valve, improves the efficient of equipment mass-and heat-transfer and enlarges its operation control range.

Basic design of the present utility model promptly is that the plane plate valve is improved to globe valve.In the equipment of this class laminated board type structure, be distributed with the horizontal laminate of some in vertical direction, equally distributed passage all is improved to the venturi type air rising hole on each laminate, supporting with it is the spherical valve body that can move freely, and this valve body drops on the venturi type air rising hole can form good being sealed and matched.Can not fall to the pore position for preventing that air-flow from blowing away spherical valve body, set up the position-limited rack of a spherical valve body especially above the venturi air rising hole, it can guarantee that spherical valve body can only keep certain scope of activities.Along with the minimizing of throughput can automatically reset to the venturi air rising hole, stuck phenomenon can not appear.Like this, if the upper edge of venturi air rising hole is suitably processed, and grind apolegamy with spherical valve body, the sealing effectiveness that its low-flow falls after rise naturally can improve greatly.Certainly, make-overcome basically toward the shortcoming of float valve or lead valve because the smooth no rib in edge of spherical valve body can reduce vapour lock again widely.How further specify goal of the invention of the present utility model below in conjunction with accompanying drawing realizes:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation that adds the mist separation hood.

Wherein 1 is laminate, and 2 is the venturi air rising hole, and 3 is spherical valve body, and 4 is the spherical valve body position-limited rack, and 5 is the mist separation hood, and 5A is an aperture, and 5B is a fixing feet, and 6 is liquid.

Can find out obviously that from accompanying drawing innovation of the present utility model is the characteristic that has made full use of spherical valve body random balance in limited range.Earlier transform common passage as venturi type air rising hole 2 on laminate 1, this will help the collection of air-flow greatly and pass through.And make the spherical valve body 3 and the upper edge of venturi air rising hole that bigger contact area be arranged, and produce good sealing effectiveness by the mill processing of further spreading out.Spherical valve body position-limited rack 4 is in order to keep the limited scope of activities of spherical valve body, make its can not because of air-flow overrun out of control, can't reset.Position-limited rack 4 is fixed on the laminate 1, venturi air-filled pore 2 tops.Because the effect of position-limited rack 4 makes spherical valve body 3 have an extreme position, has also just determined its limit throughput.To the operation of different liquid, gas the time, need the different limit flow of control, the material proportion of spherical valve body be can suitably change, or hollow ball, bulbus cordis or the like in midair used.The character of the radius of spheroid and venturi air rising hole and treatment fluid gas is complementary.

When gas load in the entire equipment is light, be to be in the bubbling operating mode basically on the laminate.Spray regime appears on the laminate when gas load is heavier, and with serious entrainment.Improve spray regime for reducing mist, we add a mist separation hood 5 in this device.Its whole cylindrical handstand tubbiness is established uniform aperture 5A on the cover sidewall.Be located on laminate by fixing feet 5B, outside the position-limited rack 4, and make the cover 5 and laminate 1 between leave the gap.This device adds and can improve the disposal ability of equipment and the modification scope of this device greatly.

The treatment effeciency and the ability of the fractionating column that is designed to according to above structure, absorption tower, conditioning Tower all are significantly improved.The hardover failure rate reduces greatly, can foretell in gas-liquid mass transfer, heat-transfer equipment and will be used widely.
