Description

Technical Field

[0001] The invention relates to the technical field of purification equipment, and in particular to a high-efficiency gas purification equipment. Background Art

[0002] Most gas purification technologies use adsorbents and catalysts to remove trace impurities such as nitrogen, oxygen and water from high-purity gases through adsorption and catalysis at room temperature or variable temperature. The most common equipment is the molecular sieve purifier.

[0003] At present, the structure of molecular sieve purifiers is mainly vertical axial flow and horizontal. Due to its own structure, it is difficult to achieve uniform distribution of airflow, and the airflow must repeatedly pass through the molecular sieve after adsorption, causing increased flow resistance and increased energy consumption. When the adsorbent in the molecular sieve is saturated with the adsorption of a certain impurity component, in order to meet the purification index, the adsorbent must be replaced or regenerated. However, in the existing molecular sieve purifiers, it is impossible to ensure that the adsorbent in each area reaches the adsorption saturation state. When one area reaches saturation, it generally needs to be replaced and regenerated, otherwise it will lead to a decrease in purification quality. However, this will increase the frequency of adsorbent replacement or regeneration, wasting resources and time.

[0004] Different batches of raw gas have different impurity concentrations, which will affect the purification efficiency in the molecular sieve purifier. Existing molecular sieve purifiers cannot adjust the purification efficiency of raw gas with different impurity concentrations, resulting in reduced purification quality or inability to fully utilize the molecular sieve.

[0035] like Figure 1-3As shown, the present invention provides a gas efficient purification device, comprising: a tank body 100, a plurality of legs 200 are arranged at the bottom of the tank body 100, and a raw gas inlet pipeline 123 and a purified gas outlet pipeline are respectively arranged at the bottom and top of the tank body 100; the tank body 100 has a central axis L1, and the central axis L1 has N radial planes that are evenly distributed and extend outward from the central axis, wherein N is an integer much greater than 1; an upper baffle 130 and a lower baffle 150 are respectively arranged at the upper and lower ends of the tank body 100, and the upper baffle 130 and the lower baffle 150 are both arranged along the central axis L1, and the upper baffle 130 can rotate around the central axis Line L1 rotates, and the lower partition 150 is fixedly connected to the tank body 100; the upper partition 130 and the lower partition 150 divide the inner cavity of the tank body 100 into a driving space, a purification space and an air intake space from top to bottom, and the raw gas inlet pipeline 123 is connected to the air intake space, the air intake space is connected to the purification space, and the purification space is connected to the purified gas outlet pipeline; M molecular sieve units 300 and alumina outer covers 140 are sequentially arranged in the purification space from the inside to the outside, where M is an integer greater than 1; the M molecular sieve units 300 and the alumina outer cover 140 are all arranged along the central axis L1, and the alumina outer cover 140 is a cylindrical structure.

[0036] like Figure 4-7As shown, in the first state, the M molecular sieve units 300 can be regarded as cylindrical structures formed by sequentially bonding N molecular sieve blocks 400, and the N molecular sieve blocks 400 of each molecular sieve unit 300 are respectively located on N radial planes; N downward slide grooves 152 are provided on the upper surface of the lower partition 150 and around the central axis L1, and these N downward slide grooves 152 are respectively arranged along the corresponding radial planes; N upper slide grooves are provided on the lower surface of the upper partition 130 and around the central axis L1, and these N upper slide grooves are also respectively arranged along the corresponding radial planes; the upper and lower surfaces of each molecular sieve block 400 are respectively vertically provided with upper slide columns and downward slide columns. Column 430, and in two adjacent molecular sieve units 300, the upper sliding column and the lower sliding column 430 of each molecular sieve block 400 of one molecular sieve unit 300 are respectively located in the middle of the inner side of the upper surface and the middle of the outer side of the lower surface of the molecular sieve block 400, and the upper sliding column and the lower sliding column 430 of each molecular sieve block 400 of the other molecular sieve unit 300 are respectively located in the middle of the outer side of the upper surface and the middle of the inner side of the lower surface of the molecular sieve block 400; the upper sliding column and the lower sliding column 430 of each molecular sieve block 400 are respectively slidably set in the upper slide groove and the lower slide groove 152; the upper sliding column and the lower sliding column 430 can be rotated a certain angle and moved a certain distance in the upper slide groove and the lower slide groove 152 respectively. In the first state, the upper sliding column and the lower sliding column 430 of each molecular sieve block 400 are both located on the radial plane corresponding to the molecular sieve block 400. The N upper sliding columns of each molecular sieve unit 300 are all located on a circle whose center falls on the central axis L1, and the N lower sliding columns 430 of each molecular sieve unit 300 are all located on another circle whose center falls on the central axis L1. A driving mechanism for driving the upper partition 130 to rotate around the central axis L1 is provided in the driving space. When the upper partition 130 rotates around the central axis L1, it pushes one end of each molecular sieve block 400 to deviate from its corresponding radial plane, and the M molecular sieve units 300 are transferred from the first state to the second state, as shown in FIG. Figure 8 , 9 shown.

[0037] For Figure 6 In the first state shown, the plurality of molecular sieve units 300 are all in a complete cylindrical structure. The N molecular sieve blocks 400 of the same molecular sieve unit 300 can be regarded as being formed by cutting a cylinder with N uniformly distributed radial planes, except that an alumina shell 420 is provided around each molecular sieve block 400. Figure 4 In the gas purification process, the raw gas moves radially toward the central axis L1 from the annular space between the tank body 100 and the alumina outer cover 140, and passes through the M molecular sieve units 300 from the outside to the inside. Therefore, in the first state, the radial thickness of each and all molecular sieve units 300 is the largest, that is, the purification equipment at this time is suitable for purifying raw gas with extremely high impurity concentration.

[0038] For different batches of raw gas, the impurity concentration is often different. When the impurity concentration is large, the radial thickness of the molecular sieve unit 300 is adjusted to be larger; when the impurity concentration is small, of course, a thicker molecular sieve unit can be used to make its purification effect better, but in this case, only the outer molecular sieve unit 300 may be used to meet the purification effect, while the innermost molecular sieve unit 300 has almost no adsorbed impurities. At this time, this problem will arise: the outer molecular sieve unit 300 can easily reach the adsorption saturation state first, while the inner molecular sieve unit is not used much and has not reached saturation. However, at this time, all M molecular sieve units 300 can only be replaced or regenerated, which results in a huge waste of resources. Therefore, for raw gas with different impurity concentrations, molecular sieve units 300 with different radial thicknesses should be used.

[0039] In order to adapt to the purification of raw gas with different impurity concentrations and adopt a matching purification efficiency, the present invention adopts M multi-layer and misaligned guided molecular sieve units 300. The M molecular sieve units 300 are composed of N mutually fitted molecular sieve blocks 400, and under the action of the driving mechanism, in two adjacent molecular sieve units 300, one end of all molecular sieve blocks 400 of one molecular sieve unit 300 can deviate from the corresponding radial plane by a certain angle in one direction (for example: clockwise), and at the same time, one end of all molecular sieve blocks 400 of the other molecular sieve unit 300 deviates from the corresponding radial plane by a certain angle in the direction opposite to the previous direction (for example: counterclockwise), and in this deviation process, the downward sliding column 430 of each molecular sieve block 400 will slide outward along the downward sliding groove 152 where it is located, that is, each molecular sieve unit 300 has a tendency to expand outward as a whole, and the gap between two adjacent molecular sieve units 300 will also expand. At this time, the M molecular sieve units 300 are transferred from the first state to the second state, such as Figure 8 , 9 In the second state, each molecular sieve unit 300 is roughly cylindrical, and two adjacent molecular sieve blocks 400 are still tightly fitted, but the radial thickness of each molecular sieve unit 300 becomes smaller, which means that the purification path of the raw gas becomes shorter, so that for raw gases with different impurity concentrations, the appropriate radial thickness can be obtained by adaptively adjusting the deviation angle of the molecular sieve block 400, so that the multi-layer M molecular sieve units 300 can adsorb some impurities to a certain extent, which not only improves the purification efficiency, but also does not cause waste of resources.

[0040] like Figure 2As shown, the driving mechanism includes a mounting plate 121, a hydraulic cylinder 160 and a push plate 131, wherein the mounting plate 121 and the push plate 131 are respectively arranged along a radial plane, and the mounting plate 121 is fixedly connected to the tank body 100, the push plate 131 is fixedly connected to the upper partition plate 130, the cylinder barrel of the hydraulic cylinder 160 is fixedly connected to the mounting plate 121, and the piston rod of the hydraulic cylinder 160 is movably connected to the push plate 131. When the deviation angle of the molecular sieve block 400 needs to be adjusted, the hydraulic cylinder 160 is started, and its piston rod is extended or retracted, pushing or pulling the push plate 131 to rotate.

[0041] like Figure 6 , 7 As shown, from the outside to the inside are the first to fourth molecular sieve units 300, wherein the molecular sieve blocks 400 of the first and third molecular sieve units 300 have their upper sliding columns arranged in the middle of the inner side of their upper surfaces, and their lower sliding columns 430 arranged in the middle of the outer side of their lower surfaces; the molecular sieve blocks 400 of the second and fourth molecular sieve units 300 have their upper sliding columns arranged in the middle of the outer side of their upper surfaces, and their lower sliding columns 430 arranged in the middle of the inner side of their lower surfaces. In the first state, the upper sliding columns and lower sliding columns 430 of each molecular sieve block 400 and their respective upper slide grooves and lower slide grooves 152 are all located on the corresponding radial plane. When Figure 2 When the piston rod of the hydraulic cylinder 160 shown in the figure is extended, it will push the push plate 131 and the upper partition 130 to rotate counterclockwise around the central axis L by an angle. At this time, the upper sliding columns of the molecular sieve blocks 400 of the first to fourth molecular sieve units 300 are driven by the upper partition 130 to rotate counterclockwise by an angle, that is, one end of each molecular sieve block 400 deviates from the radial plane where it originally lies. At the same time, each molecular sieve block 400 will also move outward a certain distance along the corresponding upper slide groove and the lower slide groove 152. Finally, the four molecular sieve units 300 form the following Figure 8 , 9 Similarly, when the piston rod of the hydraulic cylinder 160 retracts, the push plate 131 and the upper partition plate 130 rotate clockwise around the central axis L by an angle, and each molecular sieve block 400 rotates clockwise and moves inward, returning from the second state to the first state.

[0042] Furthermore, in the second state, the inner and outer M molecular sieve blocks 400 corresponding to the same radial plane are arranged in a zigzag route. The reason for this is that although two adjacent molecular sieve blocks 400 fit closely to each other, gas can still easily pass through between the two molecular sieve blocks 400. In this way, when gas passes between the two molecular sieve blocks 400 of a molecular sieve unit 300 in the outer layer, this part of the gas will hit the side of the molecular sieve block 400 of the adjacent molecular sieve unit 300 head-on, and it is difficult to continue to pass between the two molecular sieve blocks 400. Then, this part of the gas can be effectively adsorbed to ensure the purification effect.

[0043] Obviously, for the M molecular sieve units 300 of the present invention, the volumes of the M molecular sieve blocks 400 on a radial plane decrease from outside to inside, that is, the adsorption capacity of the M molecular sieve units 300 decreases from outside to inside. Figure 6 , 7 The four molecular sieve units 300 shown in the first state, for a raw gas with an impurity concentration of 10%, from the outside to the inside, after adsorption by the first to fourth molecular sieve units 300, the gas impurity concentrations are 6%, 3%, 1% and 0 respectively. This is also consistent with the demand that the gas has fewer impurities as it goes further, and the requirement for the adsorption capacity of the molecular sieve is also reduced. Therefore, the present invention, through the arrangement of multiple cylindrical molecular sieve units 300, the purification process from the outside to the inside can make the inner and outer areas of the molecular sieve reach saturation at the same time, so that multiple molecular sieve units 300 can be replaced or regenerated together, saving resources and time.

[0044] The raw gas inlet pipe 123 is arranged obliquely relative to the central axis L1. The raw gas to be purified enters the inlet space inside the tank body 100 from the raw gas inlet pipe 123. A plurality of arc-shaped raw gas inlet holes 151 are provided on the annular portion of the lower partition 150 located between the tank body 100 and the alumina outer cover 140. The raw gas in the inlet space then enters the annular space between the tank body 100 and the alumina outer cover 140 from these raw gas inlet holes 151.

[0045] like Figure 4 As shown, the molecular sieve block 400 includes an alumina shell 420 and a molecular sieve 410 filled therein. The M molecular sieve units 300 from outside to inside are used to adsorb the impurity-containing gas layer by layer.

[0046] The radial thicknesses of the M molecular sieve units 300 are all consistent, so the volumes of the molecular sieve blocks 400 on different layers gradually decrease from the outside to the inside.

[0047] The upper partition 130 is provided with an upper through hole along the central axis L1, and a purified gas air guide pipe is provided on the upper side of the upper through hole; a gas collecting mechanism 110 is provided at the top center of the tank body 100, and a purified gas outlet hole 111 is provided on the side of the gas collecting mechanism 110, and the purified gas outlet hole 111 is connected to the purified gas outlet pipeline; a purified gas inlet pipe is provided at the bottom of the gas collecting mechanism 110, and the purified gas air guide pipe is connected to the purified gas inlet pipe. The purified gas enters the gas collecting mechanism 110 from the inner cavity of the innermost molecular sieve unit 300 through the purified gas air guide pipe and the purified gas inlet pipe, and finally enters the purified gas outlet pipeline from the purified gas outlet hole 111. When the molecular sieve unit 300 is regenerated, the purified gas outlet hole 111 of the gas collecting mechanism 110 is in a closed state.

[0048] The lower partition 150 is provided with a lower through hole along the central axis L1, and a regeneration gas guide pipe is provided at the lower side of the lower through hole; a regeneration gas inlet mechanism 120 is provided at the bottom center of the tank body 100, a regeneration gas inlet hole 122 is provided on the side of the regeneration gas inlet mechanism 120, and a regeneration gas outlet pipe is provided on the top of the regeneration gas inlet mechanism 120, and the regeneration gas outlet pipe is connected to the regeneration gas guide pipe. When purifying the raw gas, the regeneration gas inlet hole 122 of the regeneration gas inlet mechanism 120 is in a closed state. When the molecular sieve unit 300 is regenerated, the regeneration gas inlet hole 122 is opened, the regeneration gas enters the regeneration gas inlet mechanism 120, and then enters the inner cavity of the innermost molecular sieve unit 300 through the regeneration gas outlet pipe and the regeneration gas air duct, and then the M molecular sieve units 300 are regenerated in the opposite path to the purification process. The gas after the regeneration process first enters the annular space between the tank body 100 and the alumina outer cover 140, and then enters the intake space through the raw gas inlet hole 151, and finally is discharged from the equipment from the raw gas inlet pipe 123.

[0049] An annular guide arc plate 153 is provided between the regeneration gas guide pipe and the lower partition plate 150 to facilitate the raw gas to smoothly enter the annular space between the tank body 100 and the alumina outer cover 140 .

[0050] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
