Abstract
The present invention relates to an impact flow reactor used for liquid-phase reaction. The reactor adopts a barrel-shaped structure, a tubular structure, or a quadrate structure; two flow guiding cylinders are arranged in the middle of the reactor; the outer part of the reactor is provided with one or two pumps; the outlets of the pumps are symmetrically arranged on the feeding sides of the flow guiding cylinders; reaction materials impact in opposite directions by the conveying of the pumps and the high-speed flowing of the flow guiding cylinders, and the mixing of the reaction materials is efficiently promoted. The impact flow reactor of the present invention can not only keep the advantages of high-efficiency mixing and reaction uniformity of the current impact flow reactor, but also overcome some disadvantages of the current impact flow reactor. Because the pumps are used to form the outer circulation of the reactor so as to replace a screw impeller type structure, the structural design is simplified, the cost is reduced, and the engineering problems, such as vibration, shaft seal invalidation, etc., caused by the screw impeller type structure are also reduced. The present invention is favorable for repair, and accordingly, the failure rate is low, and the present invention is suitable for the reaction process of industrial scales.
Description
Technical field
The present invention relates to a kind of oil and chemical industry liquid--liquid phase reaction course impact flow reactor that is used for.
Background technology
For the reactive liquid solution that belongs to external diffusion control in oil and the chemical process, require reactor to provide sufficient blending space and back-mixing to greatest extent for reaction mass.
The most frequently used reactor of industrial reactive liquid solution is the batch (-type) still formula stirred reactor that band stirs facility.The shortcoming of this reactor is that back-mixing is inhomogeneous in the device, and stirring efficiency is not high, and is not suitable for continued operation.Impact flow reactor is a kind of novel chemical reactor, because material clashes mutually in the reactor, has increased the contact area of material, makes heat transfer, the corresponding increase of mass transfer rate, has promoted the chemical reaction that influenced by transmittance process to carry out.But present impact flow reactor is the structure that screw is set in guide shell, introduced a kind of submergence circulation impact flow reactor as Chinese patent ZL 00230326.4, though the impact flow reactor of this structure has improved mixing efficiency, make that the interior mixing of materials of device is more even than conventional stirred-tank reactor, but also come with some shortcomings.At first, be cantilever design because the motor shaft of screw is installed, if axle is long or rotating speed is very fast, cause the vibration of screw and motor shaft easily.Secondly, the motor shaft that screw is installed needs the installation shaft seal structure on reactor wall, increased the manufacturing cost of reactor, and the long-term operation shaft seal structure damages easily, influences the long-time running of reactor.At last, this structure is arranged on moving component in the reactor, and the probability that moving component may break down in operation process is bigger, course of reaction need be stopped this moment and keep in repair, influence the continous-stable running of device, also the upstream and downstream corollary apparatus is produced certain influence.
Summary of the invention
The objective of the invention is to overcome the deficiency of said apparatus, provide a kind of can the adaptation to require successive reaction in the petrochemical process, require material rapid mixing in device even again, and simple in structure, reliable reactor.
The present invention is used for liquid reactive impact flow reactor structure and comprises shell of reactor, symmetry is installed in the guide shell at middle part, the left and right sides in the reactor shell, form the fluid impact zone between the guide shell outlet, material inlet and outlet are set on the reactor shell, the recycle stock outlet is set on the reactor shell, and the recycle stock outlet communicates with the guide shell inlet by circulation line and material-handling pump.
Above-mentioned reactor shell can be a different shape, and as cylindrical shape, tubular or square etc., dull and stereotyped sealing or end socket hermetically-sealed construction can be adopted in the reactor two ends.Guide shell can be provided with a pair of of symmetry, and the several right of symmetry also can be set according to the scale of reactor, and as 2～6 pairs, the structure of guide shell can be various suitable tubular constructions.Material inlet can be arranged on optional position on the reactor shell, and material outlet can be arranged on the following optional position of liquid level, and inlet preferentially is arranged on the middle and upper part of housing, is preferably disposed on the top, and outlet preferably is arranged on the middle and lower part of housing, preferably is arranged on the bottom.The recycle stock outlet is arranged on the middle and lower part of reactor shell, can be provided with one, two or more, is preferably disposed on the bottom of reactor shell.The material circulation line can be provided with one the tunnel, two-way or multichannel, can adopt a material-handling pump, two material-handling pumps or a plurality of material-handling pump, a general cover or two covers of adopting of material circulation line and delivery pump.Above-mentioned this structure of tool and quantity can be determined by the design of this area general knowledge according to the character of reactor scale and material.
Impact flow reactor of the present invention had both kept present impact flow reactor high efficiency to mix and the reaction benefits on uniformity, some shortcomings of present impact flow reactor have been overcome again, owing to use pump in the reactor outer circulation, the structure that has replaced propeller type, design simplifies the structure, reduce cost, but also reduced engineering problems such as the vibration that the propeller type structure causes, the inefficacy of axle envelope.Moving component is arranged on outside the reactor, also helps maintenance, can also adopt the spares material conveying pump, the normal operation of device when not influencing fault.Impact flow reactor of the present invention adopts the mode of the outer pump circulation of reactor, makes the simple in structure of this reactor, and fault rate is lower, therefore is more suitable for plant-scale course of reaction.
Description of drawings
Fig. 1,2,3, the 4th, four kinds of impact flow reactor structural representations of the present invention.
Wherein 1 is reactor shell, and 2 is guide shell, and 3 is material-handling pump, and 4 is pump discharge, and 5 is feed entrance, and 6 are the product outlet, and 8 is the knock-on reaction district.
The specific embodiment
Further specify impact flow reactor 26S Proteasome Structure and Function of the present invention below in conjunction with accompanying drawing.
Adopt two material circulation delivery pumps among Fig. 1 and Fig. 2, adopt a material circulation delivery pump among Fig. 3 and Fig. 4, when adopting a material circulation delivery pump, can the pump discharge material be delivered to the guide shell inlet respectively with structures such as threeways.Mass transport pump discharge and guide shell connection place are designed to conical pipe among Fig. 1 and Fig. 3, the angle of conical pipe can be between 30 ℃-60 ℃, purpose is the whole cross section that reaction raw materials can be diffused into guide shell in the guide shell outlet, one annular space structure can be arranged between guide shell and the conical pipe, make the interior material of reactor form certain circulation.The mass transport pump discharge directly links by pipeline and guide shell among Fig. 2 and Fig. 4, guide shell material inlet end can be tightly connected with reactor enclosure body sidewall or end socket, for avoiding reactor bottom to form flow blind angle, the recycle stock outlet can be arranged on the reactor shell bottom margin.Reactor feed inlet 5, product outlet 6 and pump intake 7 can be installed in the subsurface arbitrary position of reactor.In order to overhaul and to clear up conveniently, also can establish a discharging hole at reactor bottom.
