Abstract

The utility model relates to a catalyzer separating device in a reactor, which belongs to the field of chemical engineering, is used for catalyzer separation in the reaction of liquid-solid two phases or gas-liquid-solid three phases for producing chemical engineering products and overcomes the defects of complex equipment, great catalyzer consumption and short service life existing during the process of separating and reclaiming catalyzer outside the reactor. The catalyzer separating device adopts the technical proposal that a close and annular separator tube which is connected with a discharge nozzle communicated with the outside of the reactor or a separator tube with one end connecting with the discharge nozzle and the other end being closed is arranged in the reactor; filter element mounting holes are distributed on the separator tube; and filter elements are arranged on the mounting holes. The utility model has the advantages that the catalyzer separating device in the reactor causes catalyzer not to be brought away by liquid in the reactor and to remain in the reactor all the time, so the working procedures of separating the catalyzer outside the reactor and adding the catalyzer into the reactor again are reduced, the production equipment is discreased, the breakage rate of the catalyzer is reduced, the chance of the catalyzer to contact the air is reduced, and the service life of the catalyzer is prolonged.

Description

Device for separating catalyst in reactor

Technical field

The utility model belongs to chemical field, is specifically related to the catalysis Ji separator behind liquid-solid two-phase or the gas-liquid-solid phase reaction.

Background technology

In the liquid-solid phase reaction technology of the liquid-solid two-phase of existing production chemical product or institute, employed catalyst all is to drain into reactor external application separator with reacted reactant liquor to separate recovery.For example adopt SiO ₂Carry the synthetic second two liquor-saturated single ethyl ether acetate fat of phosphomolybdic acid catalyst, after reaction finishes with reactant liquor outside catalyst is put into still, adopt that still is outer to be filtered or the mode separating catalyst of sedimentation.Device therefor has settling tank, bag filter.The shortcoming that exists with this way of recycling is the equipment complexity, and technological process is long.Catalyst breakage is serious, consumption is big.Increase the chance that catalyst contacts with air, made catalysqt deactivation, reduced catalyst service life.

Summary of the invention

The purpose of this utility model provides a kind of device for separating catalyst in reactor, the technology that is used for liquid-solid two-phase or gas-liquid-solid phase reaction production chemical product, direct separating catalyst in reactor overcomes existing catalyst separation and reclaims the equipment complexity that exists, and technological process is long.The shortcoming that the catalyst consumption amount is big, service life is low.。

The technical solution of the utility model is: the separator tube that a closed annular separator tube or an end link to each other with discharge nozzle, the other end seals that the discharge nozzle outer with leading to reactor is connected is installed in liquid-solid two-phase or gas-liquid-solid phase reaction device, distribution filter core installing hole is installed filter core on the separator tube on the hole.Below promptly constitute the utility model basic technical scheme.

In continuous still reactor, separator is installed in reacting appliance middle part or bottom, and in the reactor that intermittently anti-celebrating is answered, separator is installed in reactor lower part.Separator tube in the separator adopts common mechanical installation mode to be fixed in the reactor.Modes such as filter core can adopt and be threaded, flange connection, riveted joint are installed on the ring pipe.The position of other annexes is selected in the diameter of the ring footpath visual response device of ring pipe and the reactor.Diameter according to the selected ring pipe of the flow that filters.When flow is big, can adopt an above ring pipe that separator is provided with in groups.Filtering material in the utility model is selected in existing filtering materials such as fibre resin, metal, pottery, active carbon according to the physical parameter and the filtercondition of three groups of gas, liquid, solid.The filter core kind can be selected in the filter core of existing structures such as sintered filter core, line wound form filter core, multiple membrane type filter core.

In non-pressure reaction, but with the outer gases at high pressure of reactor through the pipeline of injecting reactor to pressurizeing in the reactor, discharge the liquid in the reactor.

The course of work of the present utility model is: after course of reaction finishes, open the discharge nozzle of reactor, liquid in the inside and outside pressure official post reactor of reactor sees through filter core and enters separator tube, discharge reactor through discharge nozzle again, the solid catalyst that can not see through filter core is stayed in the reactor, uses in follow-up production.

Use good effect of the present utility model to be: to take out of by the liquid that device for separating catalyst in reactor of the present utility model makes catalyst not be discharged from reactor, all the time stay in the reactor, reduced the outer process procedure that separates and in reactor, add catalyst again of reactor, reduce production equipment, reduced the consumption of catalyst.
