Description

A kind of Johnson pipe inside novel ion exchanger

Technical field

Methanol synthesis technology field is the utility model is related to, more particularly to John inside a kind of novel ion exchanger Inferior pipe.

Background technology

Ion-exchanger effect is to remove the alkali metal ion in MTO methanol used in the rectification cell of methanol synthesizer, With the technique needs of process MTO devices after satisfaction, conventional ion exchanger bottom is using Johnson's pipe in use there is scarce Fall into, the width in liquid header circulation gap, technical requirements its slit width 0.2mm can be measured by using clearance gauge, and actually survey Amount meets that 10%, the 0.15mm slit widths that only account for of 0.2mm slit widths account for 70%, and remaining only has 0.1mm, wherein between 70% 0.15mm Slot, Johnson's pipe effective depth is 260mm at present, the shortcomings that causing leakage and the big pressure difference of resin, and there is deficiency, it is impossible to The demand of social production.

In summary, for prior art the defects of, it is accordingly required in particular to Johnson's pipe inside a kind of novel ion exchanger, To solve the deficiencies in the prior art.

Utility model content

For insufficient existing for existing Johnson's pipe, influence the synthesis of methanol, the utility model proposes it is a kind of it is new from Johnson's pipe inside sub- exchanger, it is novel in design, managed by increasing Johnson, reduce Johnson's pipe gap size, so as to subtract Lack resin loss, reduce the pressure difference of system.

To achieve these goals, the technical solution of the utility model is as follows：

A kind of Johnson's pipe inside novel ion exchanger, including body, the surface of body are evenly arranged with V-type silk, V Each crosspoint of type silk and brace rod is fixed by welding mode, and the height of body is 460mm, is had additional on the outside of body Filter screen, formed with hollow gap between adjacent V-type silk, the height in gap is 0.23 ± 0.02mm.

Further, the mesh number of the filter screen is 80 mesh.

Further, described tube surfaces institute is apertured highly identical.

Fixed plate is provided with the bottom of body described in the utility model, the surface of fixed plate is provided with installation circular hole.

Further, the material that described filter screen uses is stainless steel.

The beneficial effects of the utility model are：It is simple in construction, managed by increasing Johnson, and reduce Johnson's pipe seam gap chi It is very little, the filter screen of proper density is set up in Johnson's pipe, reduces resin loss, and system pressure difference is reduced, practical performance is excellent, design Novelty, it is a kind of good innovation scheme.

Brief description of the drawings

Describe the utility model in detail with reference to the accompanying drawings and detailed description：

Fig. 1 is structural representation of the present utility model；

100- bodys in figure, 110- filter screens, 120- gaps, 130- fixed plates, 140-V type silks, 150- brace rods.

Embodiment

In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.

Referring to Fig. 1, Johnson's pipe inside a kind of novel ion exchanger, including body 100, the surface of body 100 are equal Even to be provided with V-type silk 140, each crosspoint of V-type silk 140 and brace rod 150 is fixed by welding mode, body 100 Highly it is 460mm, the outside of body 100 has additional filter screen 110, formed with hollow gap 120, seam between adjacent V-type silk 140 The height of gap 120 is 0.23 ± 0.02mm.

In addition, the mesh number of filter screen 110 is 80 mesh.The height in all gaps 120 in the surface of body 100 is identical.The bottom of body 100 Portion is provided with fixed plate 130, and the surface of fixed plate 130 is provided with installation circular hole.The material that filter screen 110 uses is stainless steel.

Socket body portion is lengthened 230m by the utility model on the basis of former Johnson's pipe, makes effective height of Johnson's pipe Spend for 460mm, while widen the gap of body, gap reaches 0.23 ± 0.02mm, and sets up filter screen, and filter screen is added in Johnson's pipe Outside, the mesh of filter screen mesh number 80, for isolating the effect of resin, reduce resin leakage.According to current actual use situation, resin leakage Phenomenon has been eliminated, while reduces the pressure difference of system, and certain effect, ion exchange resin leakage are served to the leakage of ion exchange resin downstream Downstream olefin hydrocarbon apparatus amount significantly reduces, and practical performance is excellent.

It should be understood by those skilled in the art that the utility model is not restricted to the described embodiments, above-described embodiment and Simply illustrate principle of the present utility model described in specification, on the premise of the spirit and scope of the utility model is not departed from originally Utility model also has various changes and modifications, and these changes and improvements are both fallen within claimed the scope of the utility model. The utility model requires protection scope is defined by appended claims and its equivalent.
