Abstract
The invention provides a machinable catalytic screen mesh belt. The machinable catalytic screen mesh belt comprises two pieces of screen meshes and a catalyst for filling, wherein edges of the two pieces of screen meshes are combined together in a braiding, bonding or welding manner to form a hollow flat bag shape which is internally filled with the catalyst; and an opening is sealed to prepare the plate-shaped catalytic screen mesh belt. According to the catalytic screen mesh belt provided by the invention, the catalyst can be completely wrapped by a hollow screen mesh bag so that the catalyst can be prevented from being carried into the upper layer of equipment by materials. Furthermore, a machining process is simple and the machinable catalytic screen mesh belt can be directly used; the machinable catalytic screen mesh belt can be produced into other needed shapes through subsequent machining so as to be suitable for catalytic distillation equipment with different applications; and the applicable range is wide and the application is simple and convenient. Moreover, the contact area of the catalyst and a reactant is large and the thickness of the catalytic screen mesh belt is small, so that the resistance and the energy consumption can be effectively reduced and the reaction efficiency is improved.
Description
Technical field
The invention belongs to chemical industry catalytic rectification process field, particularly relate to a kind of machinable catalyzed wire mesh band optimized for catalytic rectifying tower internal procedure and strengthen.
Background technology
In chemical industry, catalytic distillation process both responded, and had separation again, so the device in rectifying column must possess catalysis and mass transfer function simultaneously.The product that reactant is obtaining in rectifying column after catalytic reaction is separated again, proceeds with driving a reaction.But because catalyst granules conventional in current rectifying column is less, and distribution is placed in tower, and be therefore easy to be brought in upper level parts by material, result results in blockage, thus affects efficiency.
In order to fortifying catalytic distillation process, Chinese and overseas scholars have developed multiple catalytic distillation device.A kind of catalytic rectification packing of circular arrangement is disclosed in No. 201310689147.1st, Chinese invention patent application, this filler is stacked together by packing sheet, outside is outer wraps up in one deck silk screen, interior catalyst filling, then silk screen united by a seam and make assembly 1, then stack with other structured packing sheets as assembly 2 and curl into.
A kind of catalytic rectification packing with alternative flow structure is disclosed in No. 201210348018.1st, Chinese invention patent application, this filler is fitted together by packing sheet, outside is outer wraps up in one deck silk screen, interior catalyst filling, then silk screen united by a seam and make assembly A, then replacing with other structured packing sheets as assembly B, vertically place and form whole dish structured packing.
But the above-mentioned filler mentioned has following shortcoming: owing to being provided with packing sheet in silk screen, and therefore the thickness of assembly 1 or assembly A is larger, result causes resistance large, and energy consumption is higher, and reaction efficiency is low, and the contact area of raw material and catalyst is relatively little, the consumption of catalyst is difficult to regulation and control simultaneously.And process more complicated.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of machinable catalyzed wire mesh band.
In order to achieve the above object, machinable catalyzed wire mesh band provided by the invention comprises two panels silk screen and filling catalyst, wherein the edge of two panels silk screen is first combined by the mode of braiding, bonding or welding and to form hollow flat bag-shaped, inner filling catalyst, then seals and makes tabular catalyzed wire mesh band.
Described catalyzed wire mesh band can be reprocessed into corrugated or involute shape.
The thickness of described catalyzed wire mesh band is 0.3mm-20mm.
Described silk screen adopts metal, nonmetal or synthetic material silk braiding forms.
Described catalyst is graininess, spherical or strip.
On described silk screen, the diameter of mesh is less than the diameter of graininess and spherical catalyst or the minor face diameter of strip catalyst.
Catalyst can be wrapped in macaroni yarn mesh bag by machinable catalyzed wire mesh band provided by the invention completely, can prevent material from catalyst entrainment is entered last layer equipment thus.In addition, not only process is simple for it, and both can directly use, and makes other required form again by following process, to be applicable to the catalytic distillation equipment of different purposes, therefore applied widely and application is more easy.In addition, because the contact area of catalyst and reactant is large, and the thickness of catalyzed wire mesh band is less, so can effectively reduce resistance and energy consumption, improves reaction efficiency.
Accompanying drawing explanation
Fig. 1 is machinable catalyzed wire mesh band structure schematic diagram provided by the invention.
Fig. 2 is that machinable catalyzed wire mesh band provided by the invention is processed into corrugated and is arranged on structural representation in rectifying column.
Fig. 3 is the curved structural representation be arranged in rectifying column of machinable catalyzed wire mesh band working into coil provided by the invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, machinable catalyzed wire mesh band provided by the invention is described in detail.
As shown in Figure 1, machinable catalyzed wire mesh band provided by the invention comprises two panels silk screen 1 and filling catalyst 2, wherein the edge of two panels silk screen 1 is first combined by the mode of braiding, bonding or welding and to form hollow flat bag-shaped, inner filling catalyst, then seals and makes tabular catalyzed wire mesh band.
As shown in Figure 2 and Figure 3, described catalyzed wire mesh band can be reprocessed into corrugated or involute shape.
The thickness of described catalyzed wire mesh band is 0.3mm-20mm, and thickness crosses conference impact reprocessing operation.
Described silk screen 1 adopts the braiding of metal, nonmetal or synthetic material silk to form.
Described catalyst 2 is graininess, spherical or strip.
On described silk screen 1, the diameter of mesh is less than the diameter of graininess and spherical catalyst 2 or the minor face diameter of strip catalyst 2, to prevent catalyst 2 from the mesh silk screen 1 to exposing outside.
Now machinable catalyzed wire mesh band using method provided by the invention is described below: its horizontal or vertical being arranged in rectifying column can be formed whole dish filler, certainly other angle arbitrarily can also be adopted, but also can according to requirements be utilized embossing machine to be processed into the corrugated shown in Fig. 2, and make whole dish filler according to conventional method to set up; Or utilize veneer reeling machine be reprocessed into the involute shape shown in Fig. 3 and be arranged in rectifying column, to be applicable to the catalytic distillation equipment of different purposes corrugated catalyst mesh belt.
In addition, the time of contact of reactant and catalyst can be controlled as required by the method for adjustment catalyzed wire mesh tape thickness.
