Description

Technical Field

[0001] The present application relates to the technical field of drying equipment, and in particular to an air flow distribution device for a large-flux adsorption dryer. Background Art

[0002] The airflow distributor is a crucial component of an adsorption dryer. A well-designed distributor can reduce the pressure differential between the dryer's inlet and outlet. It should also fully utilize the adsorbent within the tank, avoiding blind spots that reduce adsorption efficiency and affect the adsorption and regeneration capabilities of the adsorbent. Existing, typical adsorption dryer distributors are carbon steel structures. They often use a separate pipe with an opening at the top of the dryer's tower as the distribution pipe. The aperture is slightly larger than the adsorbent to prevent leakage. Due to the carbon steel structure, it corrodes severely after use, resulting in low pipe flow. Furthermore, the aperture is too small, further reduced by corrosion, increasing resistance to the airflow distribution process. This results in a high pressure differential between the dryer's inlet and outlet. Furthermore, some adsorbent is trapped in the blind spot, leaving some adsorption areas without airflow after airflow distribution. This causes the dryer's processing capacity to fall below 80% of its designed capacity. Utility Model Content

[0003] In order to solve or partially solve the problems existing in the related art, the present application provides a large-flux adsorption dryer air flow distribution device, which can improve the operating efficiency of the dryer, ensure sufficient contact between the adsorbent and the pressurized medium through the uniform distribution of the airflow, and avoid the occurrence of adsorption blind spots.

[0004] The present application discloses an air flow distribution device for a large-flux adsorption dryer, comprising:

[0005] The main air inlet pipe is provided with a demister placement platform on the inner side of the main air inlet pipe, and a wire mesh demister is provided on the demister placement platform;

[0006] A distribution pipe is provided with distribution holes, the diameter of which is 3 to 4 times the diameter of the adsorbent particles;

[0007] and stainless steel wire mesh;

[0008] Among them, four distribution pipes are set, one end of which is sealed with a distribution pipe end sealing plate, which is placed at the bottom of the main air intake pipe and below the wire mesh demister. The distribution pipe is connected to the main air intake pipe, and the bottom of the main air intake pipe is sealed with a main pipe sealing plate; the distribution pipe is wrapped with a stainless steel wire mesh.

[0009] Optionally, the distribution pipe is arranged perpendicular to the main air intake pipe, and the distribution pipes are arranged in a row.

[0010] Optionally, the mesh openings of the stainless steel wire mesh are smaller than the adsorbent particles, and the stainless steel wire mesh is provided in three layers.

[0013] The technical solution provided by this application may have the following beneficial effects:

[0014] This device increases the flow area by adding pipes to the original pipes, and changes the original single vertical air intake pipe to adding four horizontal pipes on the vertical pipe to improve the utilization rate of the adsorbent. At the same time, the pipe holes are enlarged to 3 to 4 times the diameter of the adsorbent particles. At the same time, three layers of steel mesh with mesh slightly smaller than the adsorbent aperture are wrapped around the outside of the pipe and tied firmly with steel belts to prevent the adsorbent particles from leaking, effectively reducing the impact of equipment corrosion on the service life.

[0024] In response to the above problems, an embodiment of the present application provides an air flow distribution device for a large-flux adsorption dryer. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 The air flow distribution device of a large-flux adsorption dryer shown in the figure comprises:

[0026] The main air inlet pipe 1 is provided with a demister placement platform 2 on the inner side of the main air inlet pipe 1, and a wire mesh demister 3 is provided on the demister placement platform 2 to remove large particles of water droplets;

[0027] A distribution pipe 4 is provided with distribution holes 6 for distributing gas, and the diameter of the distribution holes 6 is set to be 3 or 4 times the diameter of the adsorbent particles;

[0028] and stainless steel wire mesh 7;

[0029] Among them, four distribution pipes 4 are provided, one end of which is sealed with a distribution pipe end sealing plate 5, which is distributed at the bottom of the main air intake pipe 1 and below the wire mesh demister 3. The distribution pipe 4 is connected to the main air intake pipe 1, and the bottom of the main air intake pipe 1 is sealed with a main pipe sealing plate 8; a stainless steel wire mesh 7 is provided to wrap the distribution pipe 4, the mesh of the stainless steel wire mesh 7 is smaller than the adsorbent particles, and the stainless steel wire mesh 7 is provided in three layers.

[0030] In this device, by adding pipes to the original pipes to increase the flow area, the original single vertical air intake pipe is changed to adding four horizontal pipes to the vertical pipe to improve the utilization rate of the adsorbent. At the same time, the pipe hole is enlarged to 3 to 4 times the diameter of the adsorbent particles. At the same time, three layers of steel wire mesh with mesh slightly smaller than the adsorbent aperture are wrapped around the outside of the pipe and tied firmly with steel belts to prevent the adsorbent particles from leaking, effectively reducing the impact of equipment corrosion on the service life. The present application can improve the operating efficiency of the dryer, ensure full contact between the adsorbent and the pressurized medium through the uniform distribution of airflow, avoid the appearance of adsorption blind spots, and thus reduce the pressure flow loss of the dryer and extend the service life of the equipment.

[0031] In one embodiment, in order to facilitate the distribution of airflow, the distribution pipe 4 is arranged perpendicular to the main air intake pipe 1, and the distribution pipes 4 are arranged in a row. At the same time, the diameter of the main air intake pipe 1 is approximately equal to the sum of the diameters of the distribution pipes 4. In this application, the so-called approximately equal does not mean that it must be equal, but a reasonable fluctuation within the range of equal numbers, slightly larger or slightly smaller. For example, if the diameter of the main air intake pipe 1 is 40 cm, then the diameter of the four distribution pipes 4 is 10 cm each, and the diameter of the main air intake pipe 1 is exactly equal to the sum of the diameters of the four distribution pipes 4. In this application, approximately equal means that the sum of the diameters of the four distribution pipes 4 can be 44 cm or 36 cm. This application is not a precision instrument, and is used for ventilation. The slightly larger or smaller sum of the diameters does not affect the use effect. Therefore, this application uses the concept of approximately equal to define the diameter relationship between the two.

[0032] In one embodiment, the stainless steel wire mesh 7 is fixed on the distribution pipe 4 by being tied with a steel belt and covers the distribution holes 6 to prevent the adsorbent from leaking.

[0033] In this application, the pressurized medium enters from the top of the adsorption tower, first passes through the wire mesh demister 3 to remove large particles of water droplets, enters the main air inlet pipe 1, and then flows through the stainless steel wire mesh 7 to the distribution holes 6 of the four horizontally symmetrical distribution pipes. Finally, the pressurized medium flows evenly from top to bottom through the desiccant in the entire adsorption tower, and the airflow leaves the dryer adsorption tower.

Furthermore, the terms include, comprise, or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed or inherent to such process, method, article, or apparatus.
