Description

Technical Field

[0001] The present application relates to the technical field of adsorbers, and in particular to an airflow distribution device for a horizontal adsorber. Background Art

[0002] The existing horizontal adsorber structure uses a stainless steel perforated plate, which is assembled and fixed according to the cross section of the cylinder. A non-perforated plate is used at the gas inlet and outlet to avoid the impact of the airflow on the bed. A stainless steel wire mesh is laid and fixed on the perforated plate to filter the powder.

[0003] In the prior art, because the adsorber has a large cross-section, the corresponding orifice plate area is large, more materials are used, and the orifice plate is thicker in consideration of its strength. The processing cycle of the uniform distribution device is long and the assembly is difficult. Due to the change in the operating temperature of the adsorber, the metal plate expands and contracts due to heat and cold, which easily leads to gaps in the joints between the uniform distribution plates, and the uniform distribution effect is reduced. Since the stainless steel wire mesh is laid flat, the flatness and difficulty of fixing the wire mesh increase, which brings inconvenience to the production of the equipment; the existence of the uniform distribution plate reduces the height of the inner cavity of the adsorber, and it is difficult for workers to enter the inner cavity of the adsorber to level the adsorbent. Summary of the invention

[0004] The technical problem to be solved by the present application is to overcome the existing defects and provide a horizontal adsorber airflow distribution device, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a horizontal adsorber airflow distribution device, comprising a molecular sieve adsorber, the inner wall of the molecular sieve adsorber is provided with a finished welded pipe, the finished welded pipe comprises an air inlet pipe, an airflow distribution hole area, a non-porous area and a stainless steel wire mesh, the air inlet pipe is connected to the non-porous area and is located in the middle of the non-porous area, the non-porous area is located in the middle of the finished welded pipe, the airflow distribution hole area is divided into two sides of the non-porous area, and the stainless steel wire mesh is located in the airflow distribution hole area.

[0006] As a preferred technical solution of the present application, blind plates are used to seal both sides of the finished welded pipeline.

[0007] As a preferred technical solution of the present application, a connecting plate is welded to one end of the blind plate.

[0008] As a preferred technical solution of the present application, a wire mesh clamp is provided on the airflow uniformly distributed hole area, and the wire mesh clamp is clamped with the stainless steel wire mesh wrapped on the airflow uniformly distributed hole area.

[0009] As a preferred technical solution of the present application, a support is provided on the outer side of the molecular sieve adsorber.

[0010] As a preferred technical solution of the present application, gas outlets are provided at both ends of the molecular sieve adsorber.

[0011] Compared with the prior art: the present application simplifies the manufacturing process, improves production efficiency, is conducive to large-scale application and reduces costs, and does not occupy valuable space inside the adsorber, providing maintenance personnel with a spacious maintenance channel, which is convenient for regular inspection and quick maintenance. The perforated area is designed to surround the finished welded pipe, which not only changes the direction of the airflow, but also ensures that the airflow can be evenly guided to the entire adsorber cavity and finally reach the adsorbent bed. This unique airflow guiding mechanism greatly improves the airflow distribution effect, improves the adsorption efficiency and processing capacity, and the wrapped design of the stainless steel wire mesh not only effectively promotes the uniform distribution of the airflow, but also assumes the responsibility of preliminary filtration, effectively blocking the particulate impurities carried in the gas and reducing the pollution to the adsorption layer.

[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0015] See also Figure 1 The present application provides a technical solution: a horizontal adsorber airflow distribution device, comprising a molecular sieve adsorber, wherein the inner wall of the molecular sieve adsorber is provided with a finished welded pipe, wherein the finished welded pipe comprises an air inlet pipe 1, an airflow distribution hole area 2, a non-porous area 3 and a stainless steel wire mesh 5, wherein the air inlet pipe 1 is connected to the non-porous area 3 and is located in the middle of the non-porous area 3, wherein the non-porous area 3 is located in the middle of the finished welded pipe, the airflow distribution hole area 2 is located on both sides of the non-porous area 3, and the stainless steel wire mesh 5 is located in the airflow distribution hole area 2.

[0016] The finished welded pipe plays the role of carrying gas circulation; its material and structure must ensure that there is no leakage of gas during the transmission process and provide a solid carrier for the uniform distribution of gas flow.

[0017] The airflow uniformly distributed hole area 2 evenly disperses the airflow entering the adsorber to the surface of the adsorbent material through the distributed micropores, which can maximize the use of the effective surface area of ​​the adsorbent, avoid the problem of insufficient adsorption or too fast saturation caused by excessive local airflow velocity, and thus improve the adsorption efficiency and processing capacity.

[0018] The non-porous area 3 is located in the center of the pipeline, which plays a role in balancing the air pressure and stabilizing the airflow direction; it reduces the airflow directly passing through the center of the pipeline, helps to maintain the pressure balance in the pipeline, reduces turbulence and energy loss caused by the airflow dynamics effect, and creates a more stable operating environment for the entire adsorption process.

[0019] The non-porous area 3 is 1.5 times the cross-sectional area of ​​the air intake pipe 1. The center of the air intake pipe 1 corresponds to the center of the non-porous area 3, so as to prevent the air flow impact at the air inlet, and allow the air flow to be diverted from the middle to the left and right sides, so that the air flow is evenly sprayed from the air flow uniformly distributed hole area 2 to the inner cavity of the adsorber, and then evenly reaches the adsorbent bed.

[0020] The hole diameter and hole spacing of the airflow uniformly distributed hole area 2 are calculated according to the cross-sectional area of ​​the inlet pipe, thereby determining the length of the opening area on the finished welded pipe.

[0021] The stainless steel wire mesh 5 covers the top of the airflow uniform distribution hole area 2, which not only strengthens the uniform distribution of the airflow, but also plays a role in preliminary filtering, effectively intercepting tiny particles or impurities that may be carried with the gas, protecting the adsorption layer from pollution, and extending the cleaning cycle and service life of the adsorber.

[0022] The precise control and efficient use of gas flow are achieved through the organic combination of the finished welded pipe, the airflow uniformly distributed hole area 2, the non-porous area 3 and the stainless steel wire mesh 5. The layout of the airflow uniformly distributed hole area 2 promotes the uniform contact between the gas and the adsorption material, the non-porous area 3 ensures the stability and efficiency of the system, and the addition of the stainless steel wire mesh 5 improves the filtering effect and the durability of the equipment.

[0023] Furthermore, blind plates 4 are used to seal both sides of the finished welded pipeline.

[0024] The use of the blind plate 4 effectively seals both ends of the finished welded pipe to prevent gas leakage in unintended paths, effectively maintaining the gas pressure stability inside the system and the efficiency of the adsorption process. Good sealing can also prevent external pollutants from entering the adsorber, maintaining the purity and efficiency of the adsorption medium.

[0025] The installation of the blind plate 4 not only plays a blocking role, but also strengthens the overall structural strength of the pipeline. Especially in high-pressure operating environments, the blind plate 4 can share part of the mechanical stress, prevent the pipeline from deformation or damage, and ensure long-term stable operation of the adsorber.

[0026] When the interior of the adsorber needs to be maintained, cleaned or inspected, the blind plate 4 facilitates quick maintenance, simplifies the maintenance process, shortens downtime and improves maintenance efficiency.

[0027] Furthermore, a connecting plate 6 is welded to one end of the blind plate 4 .

[0028] The connection plate 6 is provided so that the blind plate 4 can be connected to other system components quickly and accurately. During installation or maintenance, the sealed connection between devices can be easily achieved through simple bolt connection or flange connection, thereby improving assembly efficiency.

[0029] Furthermore, a wire mesh clamp 9 is provided on the airflow uniformly distributed hole area 2 , and the wire mesh clamp 9 is clamped with the stainless steel wire mesh 5 wrapped on the airflow uniformly distributed hole area 2 .

[0030] The wire mesh clamp 9 firmly fixes the stainless steel wire mesh 5 to ensure that it maintains a stable position when airflow passes through and does not move or fall off due to air pressure fluctuations or vibrations.

[0031] The wire mesh clamp 9 is designed to be evenly distributed on the airflow uniform hole area 2, which can help disperse the pressure acting on the stainless steel wire mesh 5 and avoid local overload, thereby protecting the wire mesh from damage, while ensuring uniform penetration of airflow and improving the efficiency and quality of gas treatment.

[0032] Furthermore, a support 7 is provided on the outer side of the molecular sieve adsorber.

[0033] The support 7 provides a stable support point for the molecular sieve adsorber, ensuring that the device can be safely fixed at a predetermined position after installation to avoid displacement or tipping due to external forces such as vibration and impact.

[0034] Reasonable support 7 effectively disperses the weight load of the adsorber when it is working, and evenly transfers it to the ground or other bearing structures, avoiding foundation damage or deformation caused by concentrated stress, and extending the service life of the equipment and surrounding building structures.

[0035] Furthermore, gas outlets 8 are provided at both ends of the molecular sieve adsorber.

[0036] The gas outlet 8 serves as the discharge port for the purified gas after the molecular sieve adsorption process is completed, ensuring that the adsorbed gas can smoothly and efficiently leave the adsorber and enter the next treatment process or be directly discharged into the atmosphere, thereby realizing a continuous gas treatment cycle.

[0037] The gas outlets 8 at both ends increase the flexibility of gas discharge, and the use of single-side or double-side gas outlets can be adjusted according to actual working conditions, thereby optimizing the gas flow path and improving the processing capacity and efficiency.

[0038] During use: the airflow enters the finished welded pipe through the adsorber inlet pipe. In order to prevent the airflow impact at the air inlet, the non-porous area 3 faces the air inlet, so that the airflow is split from the middle to the left and right sides, and flows evenly to the inner cavity of the adsorber through the airflow uniformly distributed hole area 2.

[0039] By controlling the number of holes and the hole spacing in the airflow uniform distribution hole area 2 to control the injection speed of the airflow, the impact force of the airflow can be reduced. The airflow uniform distribution hole area 2 is a circle of the finished welded pipe, so the airflow can be changed in direction, so that the airflow can be evenly guided to the entire adsorbent bed layer, thereby achieving the effect of uniform airflow distribution.

[0040] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
