Description

Technical Field

[0001] The invention relates to the technical field of air filtration, in particular to a molecular adsorber. Background Art

[0002] Molecular sieve adsorbers are widely used in air separation and purification industries, and are mainly used to remove impurities such as carbon dioxide, acetylene, and water from the air. The working process of the molecular sieve adsorber in the prior art is divided into two stages: adsorption and regeneration. When the adsorber works normally, the airflow enters from the adsorber inlet, passes through the adsorbent bed and flows out from the adsorber outlet. The regeneration process is opposite to the adsorption process. The regeneration gas enters the adsorber from the regeneration inlet, passes through the adsorption bed and flows out from the regeneration outlet.

[0003] 1. When the molecular sieve adsorber is in use or switched, it is necessary to equalize the pressure of the incoming airflow. If the flow rate and pressure of the airflow vary too much, the molecular sieve particles and activated alumina particles in the molecular sieve adsorber will be impacted, causing the neatly arranged molecular sieve particle array to be damaged. The particles will rub and squeeze each other, generating dust particles that enter the channels in the adsorber, causing blockage and reducing the adsorption efficiency.

[0004] 2. An air purification pipe is set at the front end of the molecular sieve adsorber, which mainly purifies the dust in the air. However, this air filtration pipe has disadvantages when used. When there is a lot of dust inside, the pipe needs to be disassembled and the internal filter element needs to be cleaned. This operation is troublesome and inefficient. Summary of the invention

[0005] The object of the present invention is to provide a molecular adsorber to solve the above-mentioned defects caused by the prior art.

[0006] The molecular adsorber includes an adsorption shell, a top cover and a servo motor. The top cover is arranged directly above the adsorption shell, and purification mechanisms are arranged on the left and right sides of the adsorption shell. The purification mechanisms purify the injected exhaust gas, and the molecular sieve is fully in contact with the air to improve the adsorption capacity.

[0007] The top of the top cover is provided with air inlet holes at equal intervals, and a filtering mechanism is provided inside the adsorption shell to filter dust or solid particles in the gas to prevent the exhaust gas from directly contacting the molecular sieve, thereby causing clogging of the ceramic or metal adsorption material in the molecular sieve;

[0008] A cleaning mechanism is provided inside the filter mechanism, and the cleaning mechanism is vertically lifted and lowered inside the filter mechanism, thereby performing dust removal on the filter mechanism to prevent dust from accumulating inside the filter mechanism, thereby affecting the service life of the filter mechanism;

[0009] A servo motor is symmetrically arranged in the middle of the adsorption shell, and a molecular sieve filter element is snap-connected to the outside of the purification mechanism. The two groups of molecular sieve filter elements are symmetrically arranged to increase the adsorption area of ​​the air and the packing layer, greatly improving the adsorption capacity of the device per unit volume.

[0010] Preferably, the purification mechanism includes a side sealing plate, a fastener, a side guide groove, a slider, an exhaust hole and a side flat iron sheet. The side sealing plates are symmetrically arranged on both sides of the adsorption shell, the outer side of the side sealing plates are symmetrically connected to the fasteners, the outer side of the adsorption shell is symmetrically provided with side guide grooves, the outer side of the side sealing plate is connected to the slider, one side of the side sealing plate is provided with exhaust holes at equal intervals, and the inside of the side sealing plate is connected to the side flat iron sheet.

[0011] Preferably, the side sealing plate is connected to the outer side of the side guide groove via symmetrically arranged sliding blocks.

[0012] Preferably, the side sealing plate is connected to the outer side of the molecular sieve filter element by symmetrically connecting side flat iron sheets internally.

[0013] Preferably, the outer side of the filtering mechanism includes an equipment case, an inner isolation cover, a filter element and a vortex fan. The equipment case is installed inside the adsorption shell. An inner isolation cover is arranged directly above the equipment case. Filter elements are symmetrically arranged inside the inner isolation cover. A vortex fan is arranged between two groups of filter elements. The vortex fan is symmetrically arranged directly above the equipment case.

[0014] Preferably, the servo motor is connected to the bottom end of the ball screw through a vortex fan connected to the output end.

[0015] Preferably, the cleaning mechanism includes a ball screw, a transverse bracket, a guide rod, a flexible brush strip, and an electric heating plate. The outer side of the ball screw is connected to the transverse bracket, the outer side of the transverse bracket is penetrated by a guide rod, the bottom end of the guide rod is welded to the top of the equipment case, one side of the transverse bracket is connected to a flexible brush strip, a servo motor is provided inside the equipment case, the outer side of the inner isolation cover is fitted with an electric heating plate, and the inner side of the inner isolation cover is provided with a flexible brush strip.

[0016] Preferably, the flexible brush strip is connected to the outer side of the ball screw via a transverse bracket arranged on one side.

[0017] Preferably, the adsorption shell is connected to the interior of the threaded cover via a chip removal pipe penetrating through the bottom end.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. When it is necessary to clean the filter elements of different widths, the servo motor drives the ball screw and the vortex fan to rotate synchronously, and then the ball screw drives the flexible brush bar to lift vertically, and then the flexible brush bar lifts vertically to clean the inside of the filter element, and then cleans the dust inside the filter element. In this way, there is no need to disassemble the operation, which is simple and convenient, and the dust cleaning process is fast;

[0020] 2. The side sealing plate is connected to the outer side of the side guide groove through a symmetrically arranged slider, and the side sealing plate is positioned by the slider, so as to facilitate the assembly and positioning of both sides of the side sealing plate. During use, the connection strength of the side sealing plate is increased by the symmetrically arranged side guide groove, so as to avoid the gap between the side sealing plate and both sides of the adsorption shell due to excessive strength of the exhaust gas pressure, thereby affecting the efficiency of the equipment in filtering the exhaust gas, and even causing damage and leakage of the equipment;

[0021] 3. The inner casing diverts the introduced air through the internal partition plate, and then discharges the air in stages, which facilitates air replacement and filtration in multiple directions at the same time, improving the convenience of equipment use and replacement. When the servo motor drives the vortex fan to rotate, it also drives the ball screw to rotate, which makes it easier to lift the flexible brush strip vertically, thereby meeting the cleaning efficiency of the equipment.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 8 As shown, the molecular adsorber includes an adsorption shell 1, a top cover 2 and a servo motor 7. The top cover 2 is arranged directly above the adsorption shell 1, and purification mechanisms 3 are arranged on the left and right sides of the adsorption shell 1. The purification mechanism 3 purifies the injected exhaust gas, and the molecular sieve is fully in contact with the air to improve the adsorption capacity;

[0039] The top of the top cover 2 is provided with air inlet holes 4 at equal intervals, and a filter mechanism 5 is provided inside the adsorption shell 1, and the filter mechanism 5 filters the dust or solid particles in the gas to prevent the exhaust gas from directly contacting the molecular sieve, thereby causing the ceramic or metal adsorption material in the molecular sieve to be blocked;

[0040] A cleaning mechanism 6 is provided inside the filter mechanism 5, and the cleaning mechanism 6 is vertically lifted inside the filter mechanism 5, thereby performing dust removal on the filter mechanism 5, so as to prevent dust from accumulating inside the filter mechanism 5, thereby affecting the service life of the filter mechanism 5;

[0041] A servo motor 7 is symmetrically arranged in the middle of the adsorption shell 1, and a molecular sieve filter element 8 is snap-connected to the outer side of the purification mechanism 3. The two groups of molecular sieve filter elements 8 arranged symmetrically increase the adsorption area of ​​the air and the packing layer, greatly improving the adsorption capacity of the device per unit volume.

[0042] In this embodiment, the purification mechanism 3 includes a side sealing plate 31, a fastener 32, a side guide groove 33, a slider 34, an exhaust hole 35 and a side flat iron sheet 36. The side sealing plates 31 are symmetrically arranged on both sides of the adsorption shell 1. The fasteners 32 are symmetrically connected to the outer side of the side sealing plate 31. The side guide grooves 33 are symmetrically opened on the outer side of the adsorption shell 1. The slider 34 is connected to the outer side of the side sealing plate 31. Exhaust holes 35 are opened at equal intervals on one side of the side sealing plate 31. The inside of the side sealing plate 31 is connected to a side flat iron sheet 36.

[0043] In this embodiment, the side sealing plate 31 is connected to the outer side of the side guide groove 33 through symmetrically arranged sliders 34 , and the side sealing plate 31 is positioned by the sliders 34 , thereby facilitating assembly and positioning of both sides of the side sealing plate 31 .

[0044] In this embodiment, the side sealing plate 31 is connected to the outer side of the molecular sieve filter element 8 by symmetrically connecting the side flat iron sheets 36 inside. The side flat iron sheets 36 are used to position the two sides of the molecular sieve filter element 8 to prevent the molecular sieve filter element 8 from shaking.

[0045] Embodiment 1:

[0046] During use, the electric heating plate 65 is first used to heat the interior of the adsorption shell 1. The first step of molecular sieve regeneration is to desorb the adsorbate. During the use of the molecular sieve, the adsorbate will be adsorbed on the pore wall, hindering the transmission and reaction of the molecules. Therefore, it is necessary to desorb the adsorbate from the molecular sieve. This can be achieved by heating. Heating can improve the molecular mobility between the adsorbent and the molecular sieve, thereby promoting the desorption of the adsorbate.

[0047] The molecular sieve dryer is heated to a certain temperature, usually between 200-300 degrees Celsius. The heating method can be electric heating, steam heating or other heat sources. During the heating process, the adsorbed water begins to desorb gradually. At the same time, the water vapor and other types of substances generated by the heating are directly discharged through the exhaust hole 35 set on one side to discharge harmful substances. (The molecular sieve filter element 8 is a powdery crystal with a metallic luster, a hardness of 3 to 5, a relative density of 2 to 2.8, natural zeolite is colored, synthetic zeolite is white, insoluble in water, and its thermal stability and acid resistance increase with the increase of the SiO2 / Al2O3 composition ratio. The molecular sieve filter element 8 has a large specific surface area of ​​300 to 1000 m2 / g, and the inner crystal surface is highly polarized. It is a type of high-efficiency adsorbent and also a type of solid acid. It has a high acid concentration and acid strength on the surface, which can cause a positive carbon ion type catalytic reaction. When the metal ions in the composition are exchanged with other ions in the solution, the pore size can be adjusted to change its adsorption and catalytic properties, thereby obtaining molecular sieve catalysts with different properties)

[0048] In this embodiment, the outer side of the filtering mechanism 5 includes an equipment case 51, an inner isolation cover 52, a filter element 53 and a vortex fan 54. The equipment case 51 is installed inside the adsorption shell 1. The inner isolation cover 52 is arranged directly above the equipment case 51. The filter element 53 is symmetrically arranged inside the inner isolation cover 52. A vortex fan 54 is arranged between the two groups of the filter elements 53. The vortex fan 54 is symmetrically arranged directly above the equipment case 51.

[0049] In this embodiment, the servo motor 7 is connected to the bottom end of the ball screw 61 via a vortex fan 54 connected to the output end.

[0050] In this embodiment, the cleaning mechanism 6 includes a ball screw 61, a transverse bracket 62, a guide rod 63, a flexible brush strip 64, and an electric heating plate 65. The outer side of the ball screw 61 is connected to the transverse bracket 62, and the outer side of the transverse bracket 62 is penetrated by the guide rod 63. The bottom end of the guide rod 63 is welded to the top of the equipment box 51, and one side of the transverse bracket 62 is connected to the flexible brush strip 64. The inside of the equipment box 51 is provided with a servo motor 7, the outer side of the inner isolation cover 52 is fitted with an electric heating plate 65, and the inside of the inner isolation cover 52 is provided with a flexible brush strip 64.

[0051] In this embodiment, the flexible brush strip 64 is connected to the outer side of the ball screw 61 via a transverse bracket 62 provided on one side.

[0052] Embodiment 2:

[0053] When it is necessary to clean the filter element 53 of the preliminary air filtration, the operator drives the vortex fan 54 and the ball screw 61 to rotate through the servo motor 7, so that the ball screw 61 drives the horizontal bracket 62 and the flexible brush strip 64 to clamp and lift vertically. The operator can open the top cover 2, install the flexible brush strip 64 and the horizontal bracket 62 for cleaning on the outside of the ball screw 61, and then cover the equipment through the inner isolation cover 52. According to the needs of installation and cleaning, install one side of the flexible brush strip 64 or install two groups of flexible brush strips 64, so that the two groups of filter elements 53 can be cleaned synchronously;

[0054] The transverse bracket 62 and the flexible brush strip 64 scrape off the impurities accumulated on the wall of the filter element 53, and can automatically clean the impurities accumulated on the outer wall of the annular outer net, and directly discharge the dust and debris settled inside the equipment box 51 by opening the chip discharge pipe 9. When the chip discharge is completed, the threaded cover 10 set at the bottom end of the chip discharge pipe 9 can be closed to prevent the external gas from directly flowing back into the interior of the adsorption shell 1, replacing manual cleaning, facilitating the subsequent replacement of the filter element, and improving the efficiency and quality of air filtration.

[0055] In this embodiment, the adsorption shell 1 is connected to the interior of the threaded cover 10 via a chip removal pipe 9 penetrating through the bottom end.

[0056] In practical application, this molecular adsorber includes the following working processes:

[0057] Step 1: In normal use, first install the molecular sieve filter element 8 on the outside of the side sealing plate 31, and position the outer periphery of the molecular sieve filter element 8 through the side flat iron sheet 36 provided on the outer side of the side sealing plate 31, and position the outer sides of the molecular sieve filter element 8 and the side flat iron sheet 36 through the fastener 32, and then block one side of the exhaust hole 35 provided on the outer side of the side sealing plate 31 through the molecular sieve filter element 8, so as to facilitate the discharge of filtered air;

[0058] Step 2: The operator turns on the electric heating plate 65 to heat the inside of the adsorption housing 1 and the molecular sieve filter element 8, drives the vortex fan 54 to rotate through the servo motor 7, and inhales and circulates the air inside the adsorption housing 1 through the vortex fan 54, gradually heating it to a predetermined temperature to remove moisture attached to the surface of the molecular sieve filter element 8;

[0059] Step 3: Then, the exhaust gas is directly injected into the filter element 53 through the air inlet 4 opened at the top of the pipe fitting and the adsorption shell 1, and the vortex fan 54 is driven to rotate by the servo motor 7, thereby draining the exhaust gas, and then filtering the dust and solid particles in the exhaust gas through the filter element 53, while reducing the pressure of the exhaust gas to avoid damage to the molecular sieve filter element 8 caused by excessive pressure of the exhaust gas;

[0060] Step 4: By turning off the electric heating plate 65, after completing the filtration of the particulate matter in the exhaust gas, the impurities in the discharged industrial waste gas are filtered through the molecular sieve filter element 8 arranged on both sides, and then the gas is directly discharged through the exhaust hole 35 opened on one side of the side sealing plate 31 to avoid damage caused by excessive temperature of the molecular sieve filter element 8.

[0061] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
