Abstract
Description

[0001] The present application relates to the technical field of molecular sieves, and in particular to an integrated molecular sieve adsorber with a heating function. Background Art
[0002] At present, molecular sieve adsorption technology is widely used in the fields of gas purification, separation, drying, etc. Its core lies in utilizing the selective adsorption characteristics of molecular sieves for specific gas molecules to achieve efficient purification of the gas to be treated. However, during long-term use, the adsorption capacity of molecular sieves will gradually decrease, and it is necessary to restore its adsorption performance through heating and regeneration. In the heating and regeneration process of existing molecular sieve adsorbers, the contact area between the heating device and the molecular sieve is small, and the heat transfer efficiency is low, resulting in uneven regeneration of the molecular sieve, affecting the recovery of its overall adsorption performance; due to the lack of effective support and limiting structures, the heating device is prone to displacement during operation due to factors such as thermal expansion and contraction, vibration, etc., affecting the stability and safety of equipment operation. Summary of the invention

[0010] Compared with the prior art: The efficient heating and regeneration mechanism and optimized gas flow path of this application realize the high efficiency and stability of equipment operation, and improve the overall performance of the molecular sieve adsorption process. The steam heat transfer pipe group adopts a spiral tube design, which increases the contact area with the molecular sieve, so that heat can be transferred more evenly and fully, effectively improving the regeneration efficiency.

DETAILED DESCRIPTION
[0013] 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.
[0014] See also Figure 1 The present application provides a technical solution: an integrated molecular sieve adsorber with a heating function, comprising an adsorber body 1, wherein a tubular fixing seat 2 is arranged inside the adsorber body 1, steam heat conduction pipe groups 3 are arranged between the tubular fixing seats 2, and fixed clamping seats 4 are arranged between the steam heat conduction pipe groups 3.
[0015] The adsorber body 1 provides a closed space environment to ensure that the gas to be treated can undergo effective adsorption and desorption processes therein. Its structural strength and sealing are the basis for maintaining the normal operation of the adsorber and provide a stable carrier for the installation of other internal components.
[0016] The tubular fixing seat 2 is embedded in the adsorber body 1 to fix and support the steam heat transfer tube group 3 .
[0017] The steam heat transfer pipe group 3 transfers heat evenly to the molecular sieve in the adsorber by introducing high-temperature steam; this helps to improve the heat transfer efficiency so that the molecular sieve can quickly and evenly reach the required regeneration temperature; and it provides the necessary thermal conditions for the molecular sieve to maintain its good adsorption performance and long service life.
[0018] The fixed base 4 is located between the steam heat pipe groups 3 and plays a role of fixing and positioning. The fixed base 4 ensures that the relative position of the steam heat pipe group 3 between the tubular fixed base 2 remains constant, preventing gaps or collisions between the pipe groups due to thermal expansion and contraction or other reasons. It ensures the close arrangement of the steam heat pipe groups, which is conducive to the continuous transfer of heat, and also helps to maintain the cleanliness and orderliness of the equipment, which is convenient for maintenance and inspection.
[0019] The steam heat conduction pipe group 3 adopts a spiral pipe, and a baffle 5 is arranged below the steam heat conduction pipe group 3. The baffle 5 is connected to a guide shaft seat 6 arranged on the inner wall of the adsorber body 1. An elastic seat 7 is sleeved on the outer side of the guide shaft seat 6. The upper end of the elastic seat 7 is in contact with the lower end of the baffle 5. A limited position seat 8 is arranged above the steam heat conduction pipe group 3.
[0020] The steam heat transfer pipe group 3 adopts a spiral pipe and is arranged in a spiral shape; the contact area between the pipe group and the molecular sieve is increased, so that heat can be transferred to the molecular sieve more evenly and fully, which helps to improve the regeneration efficiency and thermal energy utilization rate.
[0021] The tortuous path formed by the spiral tube prolongs the residence time of the steam in the tube, enhances the heat exchange between the steam and the tube wall, and is conducive to the full release of the steam heat, thereby better heating the molecular sieve.
[0022] Compared with the straight tube, the spiral tube can occupy a smaller volume within the limited adsorber body 1, which not only meets the heating demand but also does not affect the arrangement of other structures inside the adsorber, thus realizing the miniaturization and compactness of the equipment.
[0023] The stopper 5 is located below the steam heat conduction pipe group 3, and plays a role in supporting and fixing the steam heat conduction pipe group 3 to prevent it from sinking or shifting due to gravity, thermal expansion and contraction during operation. The stopper 5 is connected to the guide shaft seat 6 on the inner wall of the adsorber body 1 to form a stable support structure, ensuring that the steam heat conduction pipe group 3 always remains in a predetermined position, maintaining the stability and safety of the equipment operation.
[0024] The elastic seat 7 contacts the lower end of the stopper 5 to absorb and buffer the vibration and impact that may be generated during the operation of the steam heat transfer pipe group 3. The elastic seat 7 uses the elasticity and deformation capacity of its own material to effectively reduce the small vibration caused by internal airflow, temperature changes or external factors, protect the internal precision parts from damage, reduce noise, and improve the stability and comfort of equipment operation.
[0025] The main function of the limit seat 8 is to limit the upward movement of the steam heat transfer pipe group 3 to prevent it from excessively moving upward when it expands due to heat, affecting the normal operation of the equipment or causing damage to the pipe group.
[0026] Furthermore, the upper and lower ends of the adsorber body 1 are both provided with a first manhole assembly 9 and a second manhole assembly 10 .
[0027] The first manhole assembly 9 and the second manhole assembly 10 are respectively located at the upper and lower ends of the adsorber body 1, providing maintenance passages for technicians to visually check the equipment status, discover and solve potential problems in time, and ensure the normal operation of the equipment.
[0028] Furthermore, an air inlet assembly 11 and an air outlet assembly 12 are respectively disposed on the outer sides of the first manhole assembly 9 and the second manhole assembly 10 .
[0029] The air inlet component 11 and the air outlet component 12 are respectively located at the upper and lower ends of the adsorber body 1, which clarifies that the gas to be treated enters from the lower end (the air inlet component 11), is adsorbed and purified by the molecular sieve, and is discharged from the upper end (the air outlet component 12); this is conducive to full contact between the gas to be treated and the molecular sieve, thereby improving the adsorption efficiency.
[0030] Furthermore, the air inlet assembly 11 and the first manhole assembly 9 are vertically arranged, and the air outlet assembly 12 and the second manhole assembly 10 are vertically arranged.
[0031] The vertical layout can effectively prevent the treated gas from escaping directly from the outlet without being fully adsorbed (i.e., gas short circuit). Since the inlet and outlet are located at the upper and lower ends of the adsorber respectively and are perpendicular to the manhole assembly, a clear gas separation is formed, ensuring that the treated gas must pass through the molecular sieve adsorption area before reaching the outlet, thereby ensuring the integrity of gas treatment.
[0032] Furthermore, a molecular sieve outlet 13 is provided on the outer side of the adsorber body 1 .
[0033] After long-term use, the adsorption capacity of molecular sieves will gradually decrease and need to be replaced regularly. The molecular sieve outlet 13 is located outside the adsorber body 1, providing a direct access to the internal molecular sieve layer, so that the staff can remove the molecular sieve and load a new one without disassembling most of the equipment structure, which greatly simplifies the replacement process and saves time and labor costs.
[0034] Furthermore, the limit seat 8 includes a limit retaining ring 14, a limit guide shaft 15 and a lower top group 16. The limit retaining ring 14 is arranged on the inner wall of the adsorber body 1, and the limit guide shaft 15 is transferred into the limit retaining ring 14. The lower end of the limit guide shaft 15 is provided with a lower top group 16, and the lower top group 16 is connected to the upper end of the steam heat transfer pipe group 3.
[0035] The limit retaining ring 14 is fixedly arranged on the inner wall of the adsorber body 1 to provide a support point for the limit seat 8; the limit retaining ring 14 usually has a certain rigidity and heat resistance, and can withstand the thrust of the steam heat pipe group 3 during operation, while ensuring the stability of the position of the limit seat 9; the limit guide shaft 15 is transferred to the limit retaining ring 14, which guides and constrains the up and down movement trajectory of the steam heat pipe group 3 to ensure that it moves within the specified range; it will not cause excessive movement and will be effectively limited within the set range by the limit seat 8.
[0036] When in use: the air inlet assembly 11 and the air outlet assembly 12 are respectively installed through the first manhole assembly 9 and the second manhole assembly 10 to ensure that the two are perpendicular to the manhole assembly to form a reasonable gas flow path; under the action of the limit seat 8 and the stop seat 5, the vibration and impact that may be generated during the operation of the steam heat pipe group 3 are effectively absorbed and buffered to ensure the stability of the operation of the steam heat pipe group 3; through the molecular sieve outlet 13, the fresh or regenerated molecular sieve is evenly loaded into the designated area inside the adsorber to ensure that the filling density is moderate and there is no gap or accumulation; the steam source is connected to the interface of the steam heat pipe group 3 to ensure that the connection is well sealed and there is no steam leakage; the steam supply pressure and flow are adjusted to evenly transfer heat to the molecular sieve in the adsorber; so that the molecular sieve can quickly and evenly reach the required regeneration temperature; the necessary thermal conditions are provided for the molecular sieve to maintain its good adsorption performance and long service life.
[0037] 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.
