Description

Runner structure with better structural strength and fluid processing equipment including the same

The present invention relates to a processing device and its runner in the field of fluid treatment, and particularly to a runner structure with better strength.

The runner is a common fluid processing equipment. Its main body includes a fibrous base material and a processing agent powder adhered to the surface of the fibrous base material. These processing agent powders can remove, modify or modify some substances in the fluid to be processed Its physical state has the ability to change, and the fiber substrate serves as the main body of the structure to provide support performance.

Taking the honeycomb-shaped zeolite runner as an example, it is usually made by the following procedure: First, the fiber paper is coated with an adhesive, and then formed into a honeycomb-shaped structure through a special molding roller mold, and the honeycomb-shaped structure is wound according to the desired form Formed into a disk or stacked into a rectangular shape; then, sintered at 400-500 ℃ for several hours, so that the organic matter in the honeycomb structure is almost completely dispersed, leaving only the fiber inorganic substrate, the sintered inorganic base The material is impregnated with (Impregnation & wash coating) zeolite treatment agent powder, and then dried at 70-250°C to complete the preparation.

At present, the fiber substrate commonly used for runners is ceramic fiber, which has better structural strength, but because of its heavier weight, its loading efficiency of the treatment agent powder (the treatment agent per unit weight of the fiber substrate can be carried) The weight of the powder) is low, so that in order to meet the required fluid handling capacity, the weight of the runner must be heavier, most of which is contributed by ceramic fibers, and this leads to several disadvantages. First of all, the load-bearing structure of the runner box must support a large load. In addition, because the heavier ceramic fibers absorb more heat energy, the temperature of the desorption outlet is lower during the desorption operation, which makes the treatment agent desorb. The effect is poor.

Another commonly used fiber substrate is glass fiber. Unlike ceramic fiber, glass fiber is lighter in weight, so its processing agent powder carrying efficiency is significantly higher than ceramic fiber, and glass fiber substrate only absorbs more during desorption Less heat energy, the desorption outlet can maintain a higher temperature, so that the desorption efficiency can be improved. But on the other hand, the structural strength of glass fiber is lower than that of ceramic fiber. In practice, the runner that has encountered a glass fiber substrate appears to be close to the glass fiber substrate at the frame of the runner under high wind pressure. Cracked situation.

Please refer to FIG. 2 to FIG. 5. In this embodiment, the runner structure 2 includes a rotatable shaft group 20, a runner base support 30, a plurality of processing blocks 40 and a number of plates 50.

The rotating shaft group 20 may have a rotating shaft and a drum fixed on the rotating shaft and rotating synchronously, but it is not limited to this. For example, in other possible embodiments, the rotating shaft group may also be a shaft tube and rotatably sleeved on One axis. The "rotation around the axis" includes rotation around a virtual axis or rotation around a solid axis.

The runner base bracket 30 is provided on the rotating shaft group 20. In this embodiment, the rotating shaft group 20 is located at the geometric center of the rotating substrate support 30, and the rotating substrate support 30 is supported by the rotating shaft group 2. In this embodiment, the runner substrate holder 30 has a substantially wheel-shaped profile, and the runner substrate holder 30 encloses several axial processing channels 31, wherein the inner processing channel 31 has a fan-shaped profile and is adjacent to the rotating shaft group 20 The wall surface 32 of the inner processing channel 31 of the enclosure also has a fan-shaped profile; the outer processing channel 31 has a generally trapezoidal profile and is located at the outer edge of the fan-shaped processing channel 31. These trapezoidal processing channels 31 are also surrounded by the wall surface 32. Therefore, the processing channel 31 is open on the inlet side and the outlet side.

The treatment materials used depend on the target fluid components and the desired effect, but are not limited to catalysts. , Zeolite, activated carbon, polymer resin, carbon molecular sieve, porous adsorbent, or a combination thereof. Taking the porous adsorbent as an example, the treatment material may be hydrophilic or special water zeolite, activated carbon, activated alumina, silica gel, or a combination thereof, wherein the hydrophilic zeolite is, for example, A type, 13X type, or low silica to aluminum ratio Y type Zeolites and special water zeolites are, for example, ZSM-5 type, MCM type (Mobil composite of matter) or high silica-aluminum ratio Y type zeolite, and the MCM type zeolite may be, for example, MCM-41 with hexagonal structure , MCM-48 with cubic structure (cubic), MCM-50 with lamellar structure (lamellar) and other M41S zeolites. These zeolite materials can be purchased from Tianjin Nanhua Catalyst Co., Ltd., for example.

In this embodiment, the processing block 40 includes two layers of fibrous substrates, namely a first fibrous substrate 41 and a second fibrous substrate 42, wherein the first fibrous substrate 41 is adjacent to the entrance side and the second fibrous substrate 42 is adjacent to Exit side. The first and second fiber substrates 41 and 42 may have different structural strengths. For example, the first fiber substrate 41 may be substantially made of glass fibers, and the second fiber substrate 42 may be substantially made of ceramic fibers. The strength of the second fiber substrate 42 is greater than that of the first fiber substrate 41. In a work place where the wind pressure is high, the second fiber base material 42 located at the downwind (outlet side) has better structural strength and can better support the entire processing block 40, making it less prone to brittle cracking.

Since the rib 33 is embedded in the groove 44, in order to prevent the rib 33 from blocking the internal flow channel of the processing block 40 and maintaining the effective processing area of the axial fluid in the processing block, the rib 33 may be a porous mesh plate or have a honeycomb structure, Thus, the flow channels on the front and rear sides can be continued.

Since the texture of the fibrous base material is usually relatively hard and brittle, in order to avoid the collision and damage of the processing block 40 during the installation process, the aforementioned plate 50 may be installed between the block surface 43 and the wall surface 32, and these plates 50 may Several blocks of 43 have similar contours and correspond to each other, but the appearance of the plate 50 is not limited to this. In a possible embodiment, the plate 50 may be fixed on the block of the block surface 43 by silicone or other adhesive, and the adjacent plate 50 is spaced apart by the groove 44 so that the rib 33 may The groove 44 is inserted through the gap between the adjacent plates 50.

In the foregoing embodiment, the processing block has two layers of fiber substrates, but the number of fiber substrates is not limited thereto. For example, in the embodiment shown in FIG. 6, the processing block 40 has only one layer of fibrous base material, and in this embodiment, the processing block 40 does not have grooves formed on the left and right sides, but in its fan-shaped profile The grooves 44 are formed on the top and bottom surfaces, and two plates 50 are installed on both sides of the groove 44, and the wall surface 32 of the processing substrate support 30 opposite thereto is formed with a rib 33, and the rib 33 is embedded in the groove 44 to provide supporting force, and the plate 50 is sandwiched between the processing substrate holder 30 and the processing block 40. In other possible embodiments, the processing block may be formed with the aforementioned grooves on the top, bottom, left, and right blocks of the fan-shaped profile, and the walls surrounding the periphery of the processing block are also formed with the aforementioned ribs. The processing block has ribs embedded in the surfaces of the four blocks, thereby further improving the supporting force. In addition, the runner structure of this embodiment further includes a screen 60 disposed on the runner base support 30, and the screen 60 is located at the exit side of the processing block 40 and can be supported by the processing block 40. The supporting force of the processing block 40 is provided in the axial direction to resist the working wind pressure; the mesh plate can also be provided on other runner base material brackets not shown in the figure for the other processing block to bear. In other possible implementation manners, the screen may also be located on the entrance side of the processing block to resist wind pressure or other forces from another direction. In other possible implementation manners, a single-sided screen may be provided on one side of the runner substrate support, and the screen may simultaneously support and provide support for a plurality of processing blocks.

Please refer to the embodiment shown in FIG. 7. The processing block 40 of this embodiment also only has a single layer of fiber base material, and the structural strength is improved by embedding the ribs 33 and the grooves 44 with each other.
