Abstract
The utility model discloses a cyclohexanol reaction kettle. The cyclohexanol reaction kettle comprises a reaction kettle body, a stirrer, a deflection baffle plate and a settling grid plate, wherein a Teflon material layer is arranged on each of the outer surface of the deflection baffle plate and the surface of the settling grid plate. The cyclohexanol reaction kettle has the advantages as follows: the Teflon material layers are arranged on the outer surface of the deflection baffle plate and the surface of the settling grid plate, so that a solid catalyst deposition phenomenon can be avoided; characteristics such as high temperature resistance, corrosion resistance, wear resistance, sliding performance and moisture resistance of the Teflon material layers are sufficiently utilized, so that catalyst serous fluid is settled and timely slides down while flowing to the deflection baffle plate and the surface of the settling grid plate in a circulating manner, and therefore, an environment for bonding and growing the easy-bonding catalyst after bonding is broken, a defect that the solid catalyst is easy to agglomerate on an internal component of a reaction kettle settling zone is completely solved, the reaction efficiency is effectively improved, and the service lives of the deflection baffle plate and the settling grid plate are prolonged.
Description
Technical field
The utility model relates to chemical reaction container technical field, particularly a kind of cyclohexanol reactor.
Background technology
In chemical industry is produced, reactor application is very extensive, all can adopt under liquid-solid phase coexisting state, to carry out chemical reaction and produce in the production technologies such as chemical industry, coating, paint, medicine intermediate.The basic structure that the cyclohexene method is produced the reactor of cyclohexanol is to be provided with agitator, sedimentation device, heat removal apparatus etc., oil plant, water, catalyst rely on agitator evenly to mix, in reactor, there is hydration reaction, mixed material flows into decanting zone from reaction zone, thereby reach the object of separated oil plant, this is a kind of reaction unit of continuous high-efficient.There is a problem in the cyclohexanol reactor using at present: because solid catalyst is suspended in solution, form pulp-like catalyst, in circulating, enter decanting zone, then slow position precipitation flows in decanting zone, be easy to be bonded in reactor hydraulic barrier and sedimentation screen surface, and cumulative, thus chemical reaction effect affected, stop up the defects such as sedimentation hole.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cyclohexanol reactor, by the Teflon material layer with high temperature resistant, corrosion-resistant, wear-resistant, sliding and moisture resistance is set on hydraulic barrier and sedimentation screen, avoids solid catalyst to deposit on hydraulic barrier and sedimentation screen and affect reaction efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cyclohexanol reactor, comprise reactor body, agitator, hydraulic barrier and sedimentation screen, described hydraulic barrier outer surface and sedimentation screen surface are equipped with Teflon material layer.
Described Teflon material layer is for being evenly sprayed on the lip-deep Teflon material of hydraulic barrier outer surface and sedimentation screen, and the thickness of described Teflon material layer is 1 μ m-200 μ m.
Described Teflon material layer is the liner plate that is coated on hydraulic barrier outer surface and the lip-deep Teflon material of sedimentation screen, and described liner plate is fixedly connected with by means of screw with sedimentation screen with hydraulic barrier, and the thickness of described liner plate is 1mm-15mm.
A kind of in described Teflon material selection PTFE, PFA, FEP or ETFE.
Adopt the beneficial effect that technique scheme produces to be: by Teflon material layer being set on hydraulic barrier outer surface and sedimentation screen surface, can avoid the phenomenon of solid catalyst deposition to occur, make full use of high temperature resistant that Teflon material layer has, corrosion-resistant, wear-resistant, the feature such as sliding and moisture resistance, when catalyst slurry circulates to hydraulic barrier and sedimentation screen surface, sedimentation is also slided in time, destroy the environment that easy caking property catalyst bonds afterwards and grows up in precipitation, thoroughly solve the shortcoming that solid catalyst easily lumps on the internals of reactor decanting zone, effectively improve reaction efficiency, extend the service life of hydraulic barrier and sedimentation screen.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In the accompanying drawings: 1, agitator; 2, hydraulic barrier; 3, sedimentation screen; 4, downflow weir.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Reactor is combined reaction container, the design according to reaction condition to reactor structure function and configuration annex.From the charging-reaction-discharging starting, all can complete with higher automaticity pre-set reactions steps, to the temperature in course of reaction, pressure, mechanics is controlled and (is stirred, air blast etc.), the important parameters such as reactant/product concentration carry out strict regulation and control, cyclohexanol reactor comprises answers still body, agitator 1, hydraulic barrier 2 and sedimentation screen 3, in use because solid catalyst is suspended in solution, form pulp-like catalyst, in circulating, enter decanting zone, then slow position precipitation flows in decanting zone, be easy to be bonded in reactor hydraulic barrier and sedimentation screen surface, and cumulative, thereby affect chemical reaction effect, stop up the defects such as sedimentation hole.
In order to solve above technical problem, optimize reaction, raise the efficiency, increase the service life, the utility model provides a kind of cyclohexanol reactor as shown in Figure 1, its main thought is to make full use of high temperature resistant that Teflon material itself has, corrosion-resistant, wear-resistant, the characteristic such as sliding and moisture resistance, use the contact surface of the coated hydraulic barrier of Teflon material layer and sedimentation screen and reactant, avoid reactant at its surface deposition, and it is more even to flow, its structure comprises reactor body, agitator 1, hydraulic barrier 2 and sedimentation screen 3, described hydraulic barrier 2 outer surfaces and sedimentation screen 3 surfaces are equipped with Teflon material layer, Teflon material layer adopts two kinds of forms, a kind of Teflon material layer is for being evenly sprayed on the lip-deep Teflon material of hydraulic barrier 2 outer surfaces and sedimentation screen 3, the thickness of described Teflon material layer is 1 μ m-200 μ m.
Another Teflon material layer is the liner plate that is coated on hydraulic barrier 2 outer surfaces and the lip-deep Teflon material of sedimentation screen 3, and described liner plate is fixedly connected with by means of screw with sedimentation screen 3 with hydraulic barrier 2, and the thickness of described liner plate is 1mm-15mm.
Teflon material selection PTFE, PFA, a kind of in FEP or ETFE, by being set on hydraulic barrier outer surface and sedimentation screen surface, Teflon material layer can avoid the phenomenon of solid catalyst deposition to occur, make full use of high temperature resistant that Teflon material layer has, corrosion-resistant, wear-resistant, the feature such as sliding and moisture resistance, when catalyst slurry circulates to hydraulic barrier and sedimentation screen surface, sedimentation is also slided in time, the broken environment that goes easy caking property catalyst to bond afterwards and grow up in precipitation, thoroughly solve the shortcoming that solid catalyst easily lumps on the internals of reactor decanting zone, effectively improve reaction efficiency, extend the service life of hydraulic barrier and sedimentation screen.
