Description
Technical field
This utility model is related to a kind of filling bed type fixed bed catalytic reactor of petrochemical industry.
Background technology
Fixed bed catalytic reactor is widely used main equipment in petroleum chemical industry, and its basic structure can be divided into fills out
Fill two class of bed and shell and tube catalytic reactor.Fixed bed catalytic reactor is equipped with solid catalyst or solid reactant to reality
A kind of reactor of existing heterogeneous reaction process.Solidss are generally in granular form, 2～15mm of particle diameter or so, are piled into certain altitude
The bed of (or thickness).Bed transfixion, fluid are reacted by bed.It is with fluidized-bed reactor and moving bed reaction
The difference of device is that solid particle remains static.Fixed bed reactors are mainly used in realizing gas-solid catalysis, such as ammonia
Synthetic tower, sulfur dioxide contact oxidation device, hydrocarbon steam converting furnace etc..For when gas-solid phase or liquid-solid phase uncatalyzed reaction, bed
Layer then loads solid reactant.Trickle bed reactor can also belong to fixed bed reactors, and gas, liquid cocurrent passes downwardly through bed
Layer, contacts in gas-liquid-solid.The advantage of fixed bed catalytic reactor mainly has：1. back-mixing is little, and fluid can be had with catalyst
Effect contact, can obtain compared with high selectivity when reaction is with series connection side reaction；2. catalytic mechanical loss is little；3. simple structure.
The content of the invention
This utility model purpose is for the reaction efficiency for improving fixed bed catalytic reactor, there is provided a kind of filling bed type
Fixed bed catalytic reactor, convenient to use, reaction rate is fast, can effectively improve the reaction efficiency of gas and catalyst.
The technical scheme adopted by this utility model is：
A kind of filling bed type fixed bed catalytic reactor of this utility model, mainly by gas feed, distribution device in gas-fluid, device
Body, inertia packed layer, catalyst, collector ring and gas outlet composition.The gas feed and gas outlet are located at body respectively
Upper and lower, gas move across after two-layer catalyst is reacted from top to bottom after entering from the top of body and flow to gas
Outlet is flowed out；Inertia packed layer adopts triple layer designs, catalyst to design using two-layer, and the two is staggered form modular design；Gas
Body distribution apparatus is located at the lower end of air inlet, and size is identical with air inlet and is designed using perforating；Collector ring is located at gas
The upper end of outlet, uses out orifice type design, and the diameter of its aperture less than in inertia packed layer on the surface of collector ring
The diameter of implant, prevents the implant in inertia packed layer from spilling from gas outlet.
Advantage of the present utility model：Convenient to use, response speed is fast, and gas is high with the reaction efficiency of catalyst.
Description of the drawings
Fig. 1 is a kind of structural representation of filling bed type fixed bed catalytic reactor of this utility model.
Fig. 2 is the top view figure of distribution device in gas-fluid in Fig. 1.
In figure：1. gas feed, 2. distribution device in gas-fluid, 3. body, 4. inertia packed layer, 5. catalyst, 6. collector ring,
7. gas outlet.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further.
As shown in figure 1, a kind of filling bed type fixed bed catalytic reactor of this utility model, mainly by gas feed 1, gas
Distribution apparatus 2, body 3, inertia packed layer 4, catalyst 5, collector ring 6 and gas outlet 7 constitute.The gas feed 1 is gentle
Body outlet 7 is located at 3 upper and lower of body respectively；Inertia packed layer 4 adopts triple layer designs, catalyst 5 to design using two-layer, and
The two is staggered form modular design, and gas can be made fully to react with catalyst；Distribution device in gas-fluid 2 is located at the lower end of air inlet 1,
Its size is identical with gas feed 1, and is designed using circular hole formula is opened；Collector ring 6 is located at the upper end of gas outlet 7, collector ring 6
Surface uses out orifice type design, and the diameter of its aperture prevents inertia less than the diameter of inertia packed layer inner stuffing
Implant in packed layer 4 is spilt from gas outlet.
As shown in Figure 1 and Figure 2, when gas is initially entered from gas feed 1, after distribution device in gas-fluid 2, gas from
The right and left of distribution device in gas-fluid 2 and middle flow down, after ground floor inertia packed layer 4 are flow to, are uniformly distributed
Ground floor catalyst 5 is entered afterwards, and is reacted with catalyst；Reacted product is lazy by the second layer with unreacted gas
Property packed layer after be newly uniformly distributed and flow down, unreacted gas and the catalyst of the second layer is fully reacted；
When abundant reacted gaseous product is flowed out from third layer inertia packed layer 4 and is moved toward collector ring 6, by past after collector ring 6
Lower motion, flows out from gas outlet 7.
