Abstract
The present invention relates to a catalytic rectification reactor which is composed of porous gas-liquid channels and a channel fixing framework, wherein the porous gas-liquid channels are vertically and uniformly arranged in a reactor cylinder body and connected into a whole by the fixing framework; a partition board is arranged in each porous gas-liquid channel; the partition boards between the two adjacent gas-liquid channels are mutually staggered. Due to the large porosity of a catalyst bed layer, the catalytic rectification reactor designed by the present invention has sufficient gas-liquid contact by the catalyst bed layer and has the advantages of simple structure of a reaction device, low operation cost and convenient catalyst loading and unloading.
Description
The present invention relates to a kind of catalystic rectifying reactor, belong to technical field of chemical.
In industrial application, have that many gas-liquid flux are big, solid particle is the gas-liquid-solid phase reaction process of catalyst, as catalytic distillation, reactant the catalytic reaction etc. of light concentration gas and liquid.The exemplary device of such reaction as shown in Figure 1, among Fig. 1, a is a rectifying section, b is a conversion zone, c is a stripping section, d is cat head cooling for reflux and light component discharge system, e is tower still reboiler and heavy component discharge system.The core of catalystic rectifying reactor of the present invention is at conversion zone b.It is that the catalyst bed layer porosity is big that such course of reaction requires, to satisfy the needs that the gas-liquid flux is big, gas-liquid fully contacts by beds.In order to realize above-mentioned operating process, common measure is to add inner member or catalyst and inert filler are loaded in mixture etc. in reaction unit, with the porosity of increase beds.Existing these ways have been brought problems such as catalyst loading and unloading inconvenience, reaction unit complexity or increase operating cost.
The objective of the invention is to design the reactor in a kind of above-mentioned catalytic distillation device.A plurality of porous gas-liquid channels are set in catalystic rectifying reactor, with realize that the catalyst bed layer porosity is big, gas-liquid by beds can fully contact, reaction unit is simple in structure, running cost is low, catalyst loading and unloading purpose easily.
The catalystic rectifying reactor of the present invention's design is made up of porous gas-liquid channel and passage fixed frame, and the porous gas-liquid channel places reactor shell vertically, equably, fuses by fixed frame; Be provided with dividing plate in the porous gas-liquid channel, between the adjacency channel stagger mutually in the position of dividing plate.
Porous gas-liquid channel in the catalystic rectifying reactor of the present invention's design can be column, and the opening of porous channel is vertical bar shaped otch; Also can be horizontal bar shaped otch; Or leave circular aperture at the tube wall of porous channel; Or make the spring of connecting with one heart mutually become the porous gas-liquid channel.
By the catalystic rectifying reactor of the present invention's design, upper and lower side respectively has an opening, is used to load and unload catalyst, and catalyst is placed between the porous gas-liquid channel.For the catalytic distillation process, liquid flows downwards and radially vertically by beds and porous gas-liquid channel, finally discharges from the reactor lower end; Gas upwards and radially flows vertically by beds and porous gas-liquid channel, finally discharges from the reactor upper end.Gas-liquid is carried out gas-liquid mass transfer and chemical reaction during by beds, carries out gas-liquid mass transfer during by the porous gas-liquid channel.In addition, it is catalyst or inert filler that the catalystic rectifying reactor of the present invention's design also can be used for other solid, in the device of operating process such as gas gas, gas-liquid or liquid liquid and stream or adverse current.
