The gas phase distributor saves a bubble cap in the traditional gas-liquid distributor, adopts internal turbulent flow and distribution plates in special structures, perfects gas phase distribution property, reduce central flow and bias flow, and can make the gas phase to better diffuse and make the gas phase to uniformly distribute on a catalyst bed layer.
Description
Technical field
The utility model relates to a kind of petroleum refining and chemical industry equipment, particularly a kind of inner member that is used for hydrogenation reactor.
Background technology
Gasoline one-stage hydrogenation reaction both at home and abroad at present can be adopted the gas-liquid phase reaction, also can adopt gas-phase reaction.The employing tubular reactor that has, the employing heat-insulating fixed bed reactors that have.Second-stage reaction is the High Temperature Gas phase reaction, and except that BAYER company adopted tubular reactor, all the other all adopted the heat-insulating fixed bed reactors.
The gentle phase hydrogenation of fixed bed gas-liquid phase hydrogenation is the catalyst difference on the one hand, is the inner member difference on the other hand.One section fixed bed gas-liquid phase hydrogenation adopts bubble cap type distributor substantially owing to have gas-liquid two-phase and stream, as 98250778.X and 200920227768.7 two kinds of structures introducing, has the suction fragmentation concurrently, and part is added with the stream breaker of special construction; Two sections Fixed Bed Gas Phase hydrogenation are because inlet feed is in gas phase substantially, and traditional bubble cap structure distributor also can use, but exists distribution effects relatively poor, the shortcoming that droop loss is big.Partial design adopts angle cast distributor, but angle cast distributor confluxes and under center stream bigger.
And gas liquid distributor (200520032630.3) introduced a kind of gas-liquid allotter of cancelling the bubble cap structure, mixes at specific gas-liquid branch to have superiority, but still can't solve the bigger problem of main body pipe below logistics as vapor distributor.For distribution of gas,, must improve the distribution problem of vapor distributor from structure because flowability is bigger.Resolve the even gas distribution problem, vapor distributor rational in infrastructure need be set in reactor.
The utility model content
The purpose of this utility model is to provide a kind of vapor distributor, improves gas phase by the structural design that changes traditional gas-liquid allotter and distributes, and reduces the distributor pressure drop, improves distributor operational stability, operating flexibility and the scope of application.The utility model vapor distributor has broken through the design feature that traditional gas-liquid is distributed, and reduces the distributor pressure drop greatly, makes High Temperature Gas phase materials and catalyst even contact, reduces the temperature difference in the hydrogenation reactor bed cross section, improves oil quality, reduces production costs.
In order to achieve the above object, the technical scheme that the utility model adopted is: a kind of vapor distributor comprises cover plate, main body pipe and base plate, and cover plate connects base plate below the main body pipe on the main body pipe.It is characterized in that: be provided with turbulent element in the cover plate bottom, main body pipe top side wall surface has the hole equably, and even perforate is arranged on the base plate.
Described turbulent element can have multiple shape, comprises the hexagonal lobe, four jiaos of lobes, triangle flap or spinning disk etc.
Described main body pipe is a pipe, also can be the polygon pipe, the top side wall surface all has the hole equably, basic configuration comprises vertical bar seam and spiral bar seam, also can be other shapes (triangle seam, trapezoidal seam or circular) etc., basic setting principle needs wide lacking for the bar seam, perforate quantity is as required all at 2～10, the top perforate of main body pipe is in order to allow the gaseous phase materials baffling, and the material that enters the main body pipe from different perforates impacts for the first time herein and mixes, and the outlet of main body pipe lower part adopts the benefit of horn-like enlarging to be, except the location, can also enlarge the dispersion area of gaseous stream.
Described cover plate is a blind plate, prevents that material from directly entering the main body pipe from top to bottom, enters the later disturbance of main body pipe in order to strengthen gas.The shape of cover plate is corresponding with the main body tube shape, is circular flat board or polygonal panel, and thickness is equal to main body thickness of pipe wall 2～6mm, also difference can be arranged slightly.
Described base plate be shaped as conical plate, but have uniform round hole, perforate also can be set to the radially hole of bar seam, hoop bar seam or other shapes as required, also can be the combination in multiform shape hole.Perforate quantity and layout are determined according to arts demand, base plate thickness is equal to the main body tube thickness, also can be either large or small as required, base plate according to the design needs also can be set to plate with opening or perforate arc plate etc., base plate also can be the multi-layer sheet combining structure.Base plate is provided with connection leg, by connection leg base plate is welded on the lower end of main body pipe, and the quantity of connection leg 11 is 2～10, preferred 3.
A kind of vapor distributor described in the utility model is simple in structure, good stability, so adopt all-welded structure between cover plate, main body pipe and the base plate.
The utility model carries out structural design according to gas flow characteristic, and cover plate is a blind plate, prevents the gas phase short circuit of flowing; Main body pipe top has a small amount of side opening, and gas phase enters the main body pipe, collides mixing for the first time; Have a plurality of side openings in main body pipe bottom, side opening is decomposition of gaseous center stream on the one hand, is for the fusion between the overabsorption device on the other hand, improves the integral dispensing characteristic of distributor; Base plate is porous plate clocklike, has realized a plurality of minutes flow path directions, reduces center stream on the one hand, and gas phase is evenly distributed in main body pipe bottom.The vapor distributor of the utility model design can make gas be spread better and mix, and is distributed in the whole reactor cross section rapidly, and pressure drop simultaneously is less.
The utility model vapor distributor is simple in structure, and is easy for installation, and the gas phase partition characteristic is good, and pressure drop is little, and the overall structure firm stable is not yielding in hot operation; Saved the bubble cap structure of traditional gas-liquid allotter, so diameter is less, thereby reduces taking up room of internals.Obvious in petroleum refining and chemical industry gas phase hydrogenation field using value.
