Description

Technical Field

[0001] The invention relates to a fixed bed gas adsorption separation device. Background Art

[0002] When using a fixed bed gas adsorption separation device to separate mixed gases, under the premise that other working conditions have been determined, the technical parameter to ensure the gas separation effect is the space velocity of the mixed gas passing through the adsorbent. Space velocity is an indicator of the catalytic reaction efficiency of catalysts in the field of adsorption separation technology, which refers to the amount of mixed gas (corresponding to volume or mass) passing through a unit amount (volume or mass) of adsorbent per unit time.

[0003] There are two ways to express airspeed:

[0004] Volumetric space velocity = Raw material volume flow rate (20℃, m 3 ·h -1 ) / catalyst volume (m 3 )

[0005] (1)

[0006] S V ---Volume airspeed, h -1 ;

[0007] V0---Raw material volume flow rate, 20℃, m 3 ·h -1 ;

[0008] V---catalyst volume, m 3 .

[0009] Mass airspeed =Mass flow rate of raw materials (kg·h -1 ) / catalyst mass (kg)

[0010] In practical applications, under the premise of meeting a certain air velocity, the air resistance of the adsorption bed can be approximately calculated using the Ergun formula:

[0011] (2)

[0012] (3)

[0013] ΔP---pressure drop;

[0014] d p ---Adsorbent particle diameter, m;

[0015] ε---Bed porosity, %;

[0016] ρ V---Gas density, kg / m 3 ;

[0017] μ V ---Gas viscosity, Pa·s;

[0018] Z---bed height, m;

[0019] G S ---Gas mass flow rate per unit cross-sectional area, kg / m 2 ·s;

[0020] For a given adsorption bed and gas medium, d p , ε, ρ V , μ V are all constants, formula (3) can be simplified as:

[0021] make

[0022] (4)

[0023] Among them, α, β, Z, G S All are positive numbers.

[0024] In order to ensure the adsorption effect, the air velocity SV is a limited specific value, which can be deduced from formula (1):

[0025]

[0026] (5)

[0027] G v ---Gas volume flow rate per unit cross-sectional area, m / s, (m 3 / m 2 ·s)

[0028] γ---G s -G v Conversion factor, positive number

[0029] S = cross-sectional area of ​​the adsorption bed

[0030] make Positive constant

[0031] Formula (4) can be converted into

[0032] (6)

[0033] ΔP is a cubic function of Z, that is, under the premise that the adsorbent and treatment gas medium of the adsorption bed are determined and the adsorption effect of the adsorption bed is ensured, the amount of gas treated per unit time is a multiple of the volume of the adsorbent of the adsorption bed, and the pressure drop of the adsorption bed decreases significantly with the decrease of the bed thickness.

[0034] However, in specific applications, this means that a thin but large adsorption bed has a significant advantage in wind resistance parameters, but the huge area occupied by the adsorption bed poses a huge challenge to the specific implementation plan. Summary of the invention

[0035] The invention discloses a stacked gas adsorber and a waste gas purification device using the adsorber, which solves the technical problems of large adsorption bed footprint and uneven airflow distribution when gas passes through the adsorption bed.

[0036] This type of gas adsorber includes a plurality of independent adsorption units stacked up and down, and each adsorption unit includes an adsorption body bed, an upper gas channel and a lower gas channel, and the upper gas channel and the lower gas channel are collectively referred to as unit gas channels. All upper gas channels converge to an upper gas main pipe, and all lower gas channels converge to a lower gas main pipe, and the upper gas main pipe and the lower gas main pipe are collectively referred to as an adsorber main pipe. An airflow distribution balancing device is provided at least at one point in the unit gas channel of each adsorption unit, that is, the airflow distribution balancing device can be provided in the upper gas channel or the lower gas channel. Depending on the specific application, the airflow distribution balancing device can adopt a fixed or adjustable, automatic or manual throttling device, such as a throttle valve or a throttling baffle. This type of gas adsorber is called a balanced stacked adsorber.

[0037] These adsorption units are stacked in space, but in terms of application effect, they are equivalent to multiple separate adsorption beds in parallel. The gas from the main input pipeline (such as the gas main pipe above) needs to be transported to the adsorption bed of each adsorption unit through distribution and delivery pipelines of different lengths and shapes, and collected to the main output pipe (such as the gas main pipe below) through a similar collection pipeline. When the thickness of the adsorption bed is large and the gas flow rate is fast, the pressure drop generated when the airflow passes through the adsorption beds of different layers is relatively limited compared to the pressure drop generated by the distribution and delivery pipelines. Therefore, the uneven distribution of airflow between the adsorption units can be ignored. However, the purpose of setting up a multi-layer adsorber is to reduce the thickness of the bed and reduce the pressure drop generated when the airflow passes through the adsorption bed. When the bed thickness is reduced to a certain extent, the uneven distribution of airflow between the adsorption units becomes a restrictive factor.

[0038] During the adsorption separation process, the flow rate or wind speed of the adsorbed gas is usually significantly greater than that of the desorbed gas. Therefore, when the adsorption bed is desorbed and regenerated, the problem of uneven airflow distribution between the adsorption units is particularly significant.

[0039] This uneven distribution of airflow can be solved by setting an airflow distribution balance device on the unit gas channel of each adsorption unit for control. In view of the different flow rates of adsorbed gas and desorbed gas, the airflow distribution balance parameters of the airflow distribution balance device set in the unit gas channel are different in the adsorption and desorption states. In order to compensate for the difference in wind resistance generated by different adsorption units under a certain gas flow rate, a throttling device that generates different wind resistance is used to compensate for the above wind resistance difference. The overall wind resistance parameters of the throttling devices of each adsorption unit of the entire adsorber constitute the so-called balance parameters.

[0040] The specific application technical solution for this balanced stacked adsorber is to set an online dynamic adjustment automatic airflow distribution balancing device in the unit gas channel of each adsorption unit, which can balance the airflow distribution for different gas flow rates.

[0041] The balanced stacked adsorber equipped with an online dynamic automatic regulating airflow distribution balance device is used alone, and its function is similar to that of the existing ordinary fixed bed adsorption, but its wind resistance can be significantly reduced.

[0042] The above-mentioned balanced stacked adsorber can achieve better functions through the improvement of the airflow distribution balance device and other supporting devices. Each balanced stacked adsorber is provided with an upper cluster interface including all upper gas channels, and a lower cluster interface including all lower gas channels. The cluster interface divides each unit gas channel into a proximal channel close to the adsorption bed and a distal channel away from the adsorption bed. The part of the balanced stacked adsorber located between the two cluster interfaces is called the adsorber body. According to the two settings of the distal channel: one is to set an airflow distribution balance device for large flow airflow distribution balance in only one of the two proximal channels, which is called an adsorption airflow distribution balance device, and the configuration of this balanced stacked adsorber is called an adsorption configuration. The other is to set an airflow distribution balance device for small flow airflow distribution balance in one of the two distal channels, which is called a desorption airflow distribution balance device, and the configuration of this balanced stacked adsorber is called a desorption configuration. When used, the main part of the balanced stacked adsorber is driven by a mechanical device and the balanced stacked adsorber can be switched between the two configurations by switching the cluster interface. The airflow balancing system composed of two airflow balancing configurations is called a binary airflow balancing device.

[0043] When the balanced stacked adsorber equipped with the above-mentioned binary airflow balancing device is applied to a gas adsorption separation device or an exhaust gas purification device, it is necessary to set up at least two (including) balanced stacked adsorbers including adsorption configuration and regeneration configuration. These adsorbers are divided into two groups, an adsorption group and a regeneration group. The balanced stacked adsorber can be transferred between the two groups by switching the cluster interface under the drive of a mechanical device.

[0044] When the adsorbed gas passes through the adsorber of the adsorption group, the adsorbate components are captured by the adsorbent and separated from the non-adsorbate components. The gas adsorber that reaches a certain degree of saturation is switched to the regeneration group. When the desorbed gas passes through the adsorber of the desorption group, the adsorbate is separated from the adsorbent and carried out, completing the regeneration of the adsorbent in the adsorber.

[0045] When the adsorbed gas passes through the adsorption group balanced stacked adsorber, the adsorption airflow distribution balancing device works to keep the airflow between each adsorption unit balanced. When the desorbed gas passes through the desorption group balanced stacked adsorber, the adsorption configuration will not produce throttling effect when the airflow is small, and the desorption airflow distribution balancing device works to keep the airflow between each adsorption unit balanced. In this way, after the gas adsorption separation device is debugged for specific operating parameters, the two airflow balancing devices for large and small flow airflow distribution balance do not need to be adjusted during operation, which can simplify the automatic control system, reduce the failure points of the equipment, and improve the reliability of equipment operation.

[0046] Improvements are made to the number of balanced stacked adsorbers in the above-mentioned gas adsorption separation device and the way they are transferred between the adsorption group and the regeneration group. The specific solution is that all the balanced stacked adsorber bodies are sequentially arranged on a rotating body that can rotate around a fixed axis, and the pipes and peripheral devices connecting these balanced stacked adsorber bodies are arranged on a fixed ground, and the movement of the rotating body is used to complete the switching and transfer of the balanced stacked adsorber bodies between the adsorption group and the regeneration group. During operation, the adsorbed gas passes through each balanced stacked adsorber of the adsorption group in turn, and the desorbed gas passes through each balanced stacked adsorber of the regeneration group in turn. This technical solution enables the exhaust gas purification device to take into account both high concentration ratio and low emission concentration. The peripheral devices include all necessary devices required for the gas adsorption separation device, such as adsorption / desorption gas source, air pump, gas heating device, etc., in addition to the adsorber.

[0047] The improvement of the applicable adsorption mechanism and application scope of the gas adsorption separation device is that the separation principle is temperature swing adsorption, and the regeneration group is divided into a desorption sequence and a thermal regeneration sequence. The desorption sequence and the thermal regeneration sequence are both provided with one or more balanced stacked adsorbers. When working, the desorbed gas passes through each balanced stacked adsorber of the thermal regeneration sequence and the desorption sequence in turn. This technical solution can improve the heat utilization efficiency of the gas adsorption separation device during the desorption and regeneration process.

[0048] Secondly, the separation principle is temperature-swing pressure-swing adsorption. The adsorption group is the same as temperature-swing adsorption. The regeneration group is divided into a temperature-rising desorption sequence and a pressure-reducing desorption sequence. Both the temperature-rising desorption sequence and the pressure-reducing desorption sequence are provided with one or more balanced stacked adsorbers. The desorbed gas circulates through the temperature-rising desorption sequence and overflows the desorbed gas carrying the adsorbent. The negative pressure desorbed gas passes through each balanced stacked adsorber of the pressure-reducing desorption sequence in turn, carrying the adsorbent overflowed from the pressure-reducing desorption and the residual heat to leave the pressure-reducing desorption sequence. This technical solution can maximize the concentration of the adsorbent in the desorbed gas, further improve the adsorption concentration ratio, and recycle the adsorbent.

[0059] Example 1

[0060] Balanced stack adsorber with automatic air flow distribution balance, see attached Figure 1 .

[0061] It includes 5 independent adsorption units 1 stacked up and down, each of which includes an adsorption body bed 11, an upper gas channel 121 and a lower gas channel 122, which are collectively referred to as unit gas channels 12. All upper gas channels converge to an upper gas main pipe 21, and all lower gas channels converge to a lower gas main pipe 22, which are collectively referred to as adsorber main pipes 2. An automatic gas flow distribution balancing device 3 equipped with an adjustment controller 31 is provided on the upper gas channel 121 of each adsorption unit.

[0062] When this adsorber is used in a temperature swing adsorption process, the normal temperature adsorption gas passes through the adsorption bed 11 from bottom to top, and the high temperature desorption gas passes through 11 from top to bottom. During the adsorption process, the airflow distribution balance device operates with large airflow distribution balance parameters. During the desorption process, the airflow distribution balance device operates with small airflow distribution balance parameters.

[0063] Example 2

[0064] Balanced stack adsorber with binary gas flow distribution balance, see attached Figure 2-4 .

[0065] On the basis of Example 1, each balanced stacked adsorber is provided with an upper clustering interface 41 including all upper gas channels, and a lower clustering interface 42 including all lower gas channels. The clustering interface 4 divides each unit gas channel into a proximal channel 123 close to the adsorption bed 11 and a distal channel 124 far from the adsorption bed. The portion of the balanced stacked adsorber located between the two clustering interfaces 4 is called the adsorber body D0. The airflow distribution balancing device has two configurations according to the different settings of the distal channels: one is to set an airflow distribution balancing device 32 for large flow airflow distribution balancing only in one of the proximal channels, which is called an adsorption configuration, such as Figure 2 Another method is to set a flow distribution balancing device 33 for balancing the small flow flow distribution in one of the distal channels, which is called a desorption configuration, such as Figure 3 When used, the D0 part of the balanced stack adsorber body can be converted between two configurations by switching the cluster interface under the drive of a mechanical device.

[0066] Usually, the air flow distribution balancing device 33 for balancing the small flow air flow distribution is arranged on the gas channel at the upper end of the balanced stack adsorber, such as Figure 2 The air flow distribution balancing device 32 for balancing the large flow air flow distribution can be arranged on the gas channel above the balanced stacked adsorber, such as Figure 3, or on the gas channel below, such as Figure 4 .

[0067] Example 3

[0068] An exhaust gas purification device with a single balanced stacked adsorber equipped with an online dynamic automatic air flow distribution balancing device, see attached Figure 1 , 5 .

[0069] The technical solution in the figure is configured with other peripheral devices supporting the operation of the adsorption separation device on the basis of a single balanced stack adsorber D equipped with an online dynamically automatic airflow distribution balancing device 31, including a waste gas source WG, a waste gas pump 62, a lower three-way valve 63, a waste gas pyrolysis device TO, a desorption gas supply device 64, a desorption gas pump 65, a desorption gas heating device 66, an upper three-way valve 67 and a waste gas emission chimney 68.

[0070] When the device is working, adsorption purification operation and desorption regeneration operation are carried out alternately. During the adsorption purification operation, the waste gas from the waste gas source WG enters the balanced stack adsorber D through the non-air pump 62 and the lower three-way valve 63, and enters the waste gas emission chimney 68 through the upper three-way valve 67. During the desorption regeneration operation, the desorbed gas from the desorption gas source 64 enters the balanced stack adsorber D through the desorption gas pump 65 and the heating device 66 through the upper three-way valve 67, carrying the desorbed overflowed pollutants, and enters the waste gas pyrolysis device TO through the lower three-way valve 63, and is sent to the waste gas emission chimney 68 after pyrolysis treatment. The online dynamic adjustment automatic airflow distribution balancing device runs different airflow distribution balancing parameters in the balanced stack adsorber D during the adsorption purification operation and the desorption regeneration operation.

[0071] Example 4

[0072] The exhaust gas purification device is equipped with two balanced stacked adsorbers and a binary airflow balancing device, see the attached Figure 6 .

[0073] Two balanced stacked adsorber D stations are set, including the D1 station of adsorption configuration and the D2 station of regeneration configuration. The balanced stacked adsorber body D0 can be transferred between the two configurations by switching the cluster interface under the drive of a mechanical device. The peripheral devices include an exhaust gas source WG, an exhaust gas pump 62, an exhaust gas pyrolysis device TO, a desorption gas supply device 64, a desorption gas pump 65, a desorption gas heating device 66, and an exhaust gas emission chimney 68. Here, the numbers D1 and D2 are also used to refer to the balanced stacked adsorbers located at the corresponding stations (the same below).

[0074] When the device is working, adsorption purification and desorption regeneration are carried out simultaneously. The waste gas from the waste gas source WG enters the balanced stack adsorber D1 for adsorption purification through the waste gas pump 62 and the cluster interface 421, and then enters the waste gas emission chimney 68 through the cluster interface 411. At the same time, the desorbed gas from the desorption gas source 64 enters the balanced stack adsorber D2 through the cluster interface 412 through the desorption gas pump 65 and the heating device 66, carrying the desorbed overflowed pollutants, and enters the waste gas pyrolysis device TO through the cluster interface 422, and is sent to the waste gas emission chimney 68 after pyrolysis treatment. After a certain period of time, the balanced stack adsorber D1 tends to be saturated and penetrated, the balanced stack adsorber D2 completes desorption and regeneration, the two balanced stack adsorber bodies D0 exchange positions, and the waste gas purification device enters the next operation cycle.

[0075] During the operation, the binary airflow balancing device operates the fixed airflow distribution balance parameters set during the equipment installation and commissioning process while alternating between the adsorption purification operation and the desorption regeneration operation of the balanced stacked adsorbers D1 and D2.

[0076] Example 5

[0077] Rotary switching temperature swing adsorption exhaust gas purification device, see attached Figure 7 .

[0078] On the basis of the exhaust gas purification device of Example 4, improvements are made to the number of balanced stacked adsorbers and the transfer method of the balanced stacked adsorber body D0 between the adsorption group and the regeneration group.

[0079] All the balanced stacked adsorber bodies D0 are sequentially arranged on a rotating body 7 that can rotate around a fixed axis, and the pipes 71 and other supporting devices connecting these balanced stacked adsorber bodies are arranged on a fixed ground, and the balanced stacked adsorber bodies D0 are switched between the adsorption group and the regeneration group by the rotation of the rotating body 7. In the figure, the two dotted circles, the outer circle 721 indicates the upper part of the balanced stacked adsorber, and the inner circle 722 indicates the lower part of the balanced stacked adsorber, and the arc arrow indicates the rotation direction of the rotating body 7.

[0080] During operation, the waste gas from the waste gas source WG passes through the balanced stacked adsorbers D1, D2, and D3 of the adsorption group from bottom to top and is discharged through the chimney 68. The desorbed gas from the desorption gas source 64 passes through the heat recovery balanced stacked adsorber D4, the heating device 66, the desorption balanced stacked adsorbers D5 and D6 of the regeneration group in turn, and enters the chimney 68 after being treated by the waste gas pyrolysis device TO and discharged.

[0081] In the continuous working state of the exhaust gas purification device, after a certain period of operation, the balanced stack adsorber D1 adsorbs the adsorbent in the exhaust gas to saturation, and at the same time, the cooling of the heat recovery balanced stack adsorber D4 and the desorption of the desorption balanced stack adsorber D6 are completed synchronously, the rotating body 7 rotates 60°, and the corresponding desorption balanced stack adsorber body D0 completes the transfer and switching between the grouping or functional sequence, and the entire device enters the next operation cycle.

[0082] Example 6

[0083] Rotary switching temperature and pressure swing adsorption waste gas separation and recovery device, see attached Figure 8-9 .

[0084] Based on the exhaust gas purification device of Example 5, the process principle of the exhaust gas separation and recovery device is changed from temperature swing adsorption to temperature swing pressure swing adsorption.

[0085] The adsorption group is provided with three balanced stacked adsorber stations D1, D2, and D3, and the configuration is the same as that of temperature swing adsorption. The regeneration group is further divided into a temperature rise desorption sequence and a pressure reduction desorption sequence. The way in which the balanced stacked adsorber D0 body moves and switches between the groups or sequences is the same as that in Example 5.

[0086] The temperature rise desorption sequence is provided with one balanced stacked adsorber station D6, and the pressure reduction desorption sequence is provided with two balanced stacked adsorber stations D4 and D5.

[0087] During operation, the waste gas from the waste gas source WG passes through the balanced stack adsorbers D1, D2, and D3 of the adsorption group from bottom to top and is discharged through the chimney 68. The inert desorption gas from the desorption gas source 641 circulates through the desorption gas pump 65 into the balanced stack adsorber D6, and the displaced air is discharged into the residual desorption gas pipeline 82 which is finally merged into the waste gas source pipeline. After the air replacement in the balanced stack adsorber D6 and the temperature-increasing desorption sequence desorption pipeline 81 is completed, the desorption gas source 641 is turned off. The gas heating device 66 starts to circulate and deheat the desorption gas until the adsorbent in the balanced stack adsorber D6 reaches the preset desorption temperature. During the heating process, the desorption gas carrying the adsorbent is controlled to be discharged to the decompression desorption pipeline 84 through the decompression device 83. The inert desorbed gas from the desorbed gas source 642 (or 641, not shown in the figure) passes through the two balanced stacked adsorbers D4 and D5 of the decompression desorption sequence in sequence, carrying the adsorbed material overflowed from the decompression desorption and merging with the desorbed gas from the desorption pipeline of the temperature increase desorption sequence, and the residual gas enters the waste gas source pipeline through the gas compressor 85 and the condensation separation device 86. The liquid adsorbed material separated by the condensation separation device 86 is injected into the liquid storage tank 87 for storage. If the condensation separation is thorough enough, the inert gas discharged from the condensation separation device 86 can also be returned to the desorbed gas source for recycling (not shown in the figure).

[0088] If the adsorbent in the waste gas is stable enough and easy to desorb, air can also be used as the desorption gas, and the waste gas separation and recovery device can be simplified to Fig. 9 In the structure shown, the inert gas replacement process is omitted during the desorption process.

[0089] This technical solution can maximize the concentration of the adsorbate in the desorbed gas, further increase the adsorption concentration ratio, reduce the workload of compression condensation separation, and recycle the adsorbate.
