Description
Technical field
The utility model relates to a kind of Ammoximation reaction device of heterogeneous suspension catalystic converter system.
Background technology
Cyclohexanone oxime is an a kind of important intermediate of producing caprolactam, is made by hydroxylamine salt and cyclohexanone generation oximation reaction, and the cyclohexanone oxime of generation obtains caprolactam through Beckmann rearrangement again.At present, the method for preparing cyclohexanone oxime mainly contains Raschig process (HSO), NO catalytic reduction method (NO method), phosphatic hydroxylamine method (HPO), cyclohexanone oxamidinating method (HAO).The sulphur ammonium of HSO method, NO method complex process and by-product low value wherein; Though the HPO method is by-product sulphur ammonium not, technical process requires meticulous, and operation easier is big, and has NOx to produce, and has an environmental protection difficult problem.Have the problem that the amidoxime method has overcome above-mentioned three aspects only, the preparation method is simple, by-product sulphur ammonium not, and therefore a no environmental protection difficult problem quite is subjected to the favor of caprolactam industry in recent years.
The amidoxime legal system is equipped with cyclohexanone oxime at first by the invention of Italian ENI company, and at first set up and produce 10000 tons amidoxime experimental rig per year in Italy, built up in Japan in 2003 and produce 60000 tons amidoxime chemical industry device per year, the domestic amidoxime chemical industry device of producing 70000 tons per year and producing 100000 tons per year that also built up respectively.
From the present domestic amidoxime chemical industry device ruuning situation of building up, all there are some problems.Behind Ammoximation reaction, product need be transported to carries out separating of cyclohexanone oxime and catalyst in the filter, and filter needs regular online regeneration and irregular regenerated offline, and the cycle of operation is short; Simultaneously, for guaranteeing the tangent line linear speed of filter, reactor material self-loopa amount is bigger, has increased energy consumption, and in the filter running, also is prone to the catalyst leakage phenomenon.Because catalyst interception rate is had relatively high expectations, the filter area of filter is bigger, and the filter apparatus investment is bigger.This shows that at present the Ammoximation reaction separation equipment has drawbacks such as separation process complexity, utilization of Heat of Reaction are unreasonable.
In sum, for solving all difficult problems in the caprolactam production process amidoxime chemical industry preface, energy savings reduces production costs, and amidoxime chemical industry device is improved, and is to reduce caprolactam production cost urgent problem.
The utility model content
The utility model is at the deficiency of existing Ammoximation reaction technology, Ammoximation reaction device and catalysts thereof separated improve, and adopts connect with the external filter mode of cascade filtration of built-in filter to carry out catalyst separation.
For realizing the utility model purpose, this cyclohexanone oxamidinating catalysts separator comprises the reacting tank body that is equiped with built-in filter, the reacting tank body inner bottom part is provided with the raw material feed distributor, the top is provided with the recycle stock distributor, it is characterized in that described built-in filter purified liquor outlet connects external filter inlet, external filter outlet connects storage tank.
Described built-in filter film pore directly is 0.05～1 μ m.
Described external filter film tube aperture is 0.01～0.05 μ m.
Described feed distribution device and recycle stock distributor are respectively the endless tube structure, have the distribution hole on the endless tube.
The technological progress that the utility model is obtained: because the catalyst reaction device that adopts built-in and external filter to filter step by step, avoided the catalyst leakage phenomenon in the filter running, increased security, reduced the filter area of filter, reduced equipment investment, reduce the energy consumption of reaction and catalyst operation, simplified the flow process of catalyst separation, and had characteristics such as separation process is simple, the equipment cycle of operation is long, utilization of Heat of Reaction is reasonable.
