Description

Technical Field

[0001] The invention relates to the technical field of continuous adsorption-desorption separation process, and in particular to a rotary centrally controlled multi-inlet and outlet pipeline distribution valve used in the continuous adsorption-desorption separation process. Background Art

[0002] Adsorption separation is an important material separation technology with the advantages of strong target selectivity, energy saving and low carbon, and low operating cost. It also has great application potential in the field of resource recovery. Traditional adsorption processes mostly use independent adsorption columns or fixed bed reactors with two or three adsorption columns in series, but there are problems such as "the adsorbent is not yet saturated when the adsorption operation reaches the leakage point", resulting in low adsorbent utilization. Therefore, the continuous adsorption and desorption separation process, which disperses the original reaction column into multiple series reaction columns and adopts a periodic sequential operation form, came into being. It is equipped with multiple groups of control valves to form an array for program switching. However, in this mode of operation, the number of automatic switch valves and corresponding switch control points increases exponentially with the increase in the number of series reactors. For example, 12 reactors with the same structural form only input and output materials through the upper and lower interfaces. After being connected in series, the unit reaction processes such as "adsorption-compression-steam blowing-pre-filling-desorption-compression-steam blowing-top filling" are carried out in a cyclic sequence according to the traditional fixed bed batch reaction mode. The material passages and their valves are set according to the required reaction materials and the number of reactors. The switch states of all valves are program-controlled according to a series of docking combination rules. According to rough statistics, at least 8X24 pipelines and their control valves need to be set up and 192 switch control points are arranged on the control system accordingly. Not only is the structure complex, but there is also a risk of "one valve failure paralyzing the function of the entire valve array", resulting in cumbersome operation and maintenance and complex control management. Therefore, how to conveniently and synchronously distribute and transport various process materials including raw materials, process materials and product materials between reactors and between reactors and external facilities according to process goals has become an urgent need for the further development of adsorption separation technology. Summary of the invention

[0003] The present invention is intended to provide a distribution valve for rotating and centrally controlling multiple inlet and outlet pipelines, so as to centrally and synchronously switch raw materials, process materials and product materials periodically between reactors and between each reactor and upstream and downstream supporting facilities in sequence, so as to realize an automated continuous adsorption and desorption separation process.

[0004] To achieve the above-mentioned purpose, the present invention provides a rotary centralized controlled multi-inlet and outlet pipeline distribution valve for continuous adsorption and desorption separation process, comprising: a rotor ring, a stator ring, a tangential rotating device, a control system, a reactor inlet and outlet pipeline cluster interface and a material inlet and outlet pipeline cluster interface, wherein the stator ring comprises an upper stator ring and a lower stator ring, the upper stator ring comprises an inner ring and an outer ring radially clamping a rotor ring, the rotor ring is engraved with a plurality of tangential grooves and radial channels in a three-dimensional direction, the tangential grooves are engraved along the inner and outer circumferential surfaces of the rotor ring, the radial channels are used to communicate with the tangential grooves on the inner and outer circumferential surfaces of the rotor ring, the tangential grooves on the inner circumferential surface of the rotor ring correspond to the material inlet and outlet pipeline cluster interface through the channels in the inner ring of the upper stator ring, and the tangential grooves on the outer circumferential surface of the rotor ring correspond to the reactor inlet and outlet pipeline cluster interface through the channels in the outer ring of the upper stator ring; the tangential rotating device drives the rotor ring to rotate periodically according to the time interval and radial angle set by the program.

[0005] The principle of the technical solution of the present application is as follows: the tangential rotating device drives the rotor ring to rotate at equal time intervals and equal angular intervals, so that the tangential grooves and radial channels thereon change in a periodic sequence to switch the matching and docking combination of the reactor inlet and outlet pipeline cluster interface and the material inlet and outlet pipeline cluster interface, thereby centrally and synchronously allocating and conveying all main and auxiliary raw materials, process materials and product materials required for the continuous adsorption-desorption separation process between all reactors in the reactor group and between the reactor group and the upstream and downstream supporting facilities.

[0006] As a preferred solution, in order to ensure that the rotating mating surfaces of the rotor ring and the stator ring can both ensure sufficient sealing and rotate smoothly, the distribution valve of the present application also includes a radial clamping device, the rotor ring is made of composite engineering plastic, and the radial clamping device causes the pressure on the tangential fitting surface of the rotor ring and the stator ring to fluctuate in a pulsed manner as the rotor ring rotates step by step. Specifically, the rotor ring of the composite engineering plastic is acid and alkali resistant, solvent resistant, and wear resistant, and has the characteristics of high elastic deformation and high dimensional stability, so that the pressure applied by the radial clamping device to the end face of the rotor ring can be diffused to the circumferential surface of the rotor ring to improve the sealing of the contact fitting surface. When the rotor ring rotates, the radial clamping device reduces the end pressure and moderately reduces the pressure on the circumferential contact surface between the rotor ring and the stator ring, thereby reducing the friction of rotation. After the rotor ring rotates into place, the radial clamping device restores the end pressure, thereby moderately increasing the pressure on the circumferential contact surface between the rotor ring and the stator ring, and keeping the rotor ring and the stator ring in close contact.

[0007] As a preferred solution, in order to accurately control the rotation speed and rotation angle of the rotor ring, the tangential rotation device adopts a servo motor.

[0008] As a preferred solution, penetrating rotor connecting rods are evenly arranged in the rotor ring, the rotor ring is connected and fixed to the rotor shaft disk through the rotor connecting rods, the rotor shaft disk is connected to the output rotating shaft of the servo motor, and the servo motor is controlled by a preset program of the control system to drive the rotor ring to rotate precisely in steps. After waiting in place for a set time, it quickly rotates to a set angle and repeats the cycle. The rotation angle should be sufficient to switch the tangential groove on the rotor ring from the current docking interface to the next adjacent group of interfaces, that is, the circumferential angle of the corresponding interfaces of two adjacent groups of reactors that are evenly distributed, and the rotation of the above rotation angle should be completed in a shorter time as possible.

[0009] As a preferred solution, the inner cavity ends of the upper and lower stator rings are both single-acting piston cylinder structures, and the piston cavity composed of the piston and the stator ring is provided with a compressed air interface and an exhaust pipe, and the compressed air interfaces are connected to the tees, and the qualified compressed air processed by the three-way piece enters the inner cavity ends of the upper and lower stator rings through the air pressure proportional regulating valve, the residual pressure release valve and the tee in sequence. The control system accurately controls the air pressure proportional regulating valve and the residual pressure release valve through a predetermined program, so that the end pressure of the upper and lower stator ring pistons on the rotor ring fluctuates in a pulsed manner as the rotor ring rotates in steps.

[0010] As a preferred embodiment, the reactor inlet and outlet pipeline cluster interfaces are evenly arranged on the outer circumferential surface of the outer ring of the upper stator ring, and are respectively fixedly connected to the input and output pipeline clusters of the reactor group (i.e., the material inlet and outlet pipelines of each reactor in the continuous adsorption and desorption separation process); the material inlet and outlet pipeline cluster interfaces are arranged on the inner circumferential surface of the inner ring of the upper stator ring, and are respectively fixedly connected to the material input and output pipeline clusters (i.e., the raw material input pipeline and product material output pipeline of the continuous adsorption and desorption separation process reactor group as a whole).

[0011] As a preferred solution, in order to seal and fix the stator ring, the upper stator ring and the lower stator ring are respectively provided with an upper stator ring skirt plate and a lower stator ring skirt plate, which are connected to a fixing bracket by bolts. The fixing bracket is fixed to the construction facility by anchor bolts, or the construction facility is directly used as the fixing bracket.

[0012] The rotary centralized controlled multi-inlet and outlet pipeline distribution valve adopting the technical solution of the present invention internalizes the valve array control logic of the continuous adsorption and desorption separation process into a three-dimensional flow design of a single distribution valve device. Compared with the traditional valve array continuous adsorption and desorption separation process control, there is no need to configure automatic switching valves and corresponding switching control points whose number increases exponentially with the increase in the number of series reactors, thereby avoiding the risk of "a valve failure paralyzing the function of the entire valve array", removing the limitation of the control management complexity on the number of series reactors, and realizing the continuous adsorption and desorption separation process to give full play to the advantages of adsorbent utilization efficiency while ensuring the treatment quality.

DETAILED DESCRIPTION

[0026] In order to make the purpose and technical solutions of the embodiments of the present invention clearer, the technical solutions of the specific implementation of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Generally, the whole or parts of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

In addition, the terms "1", "2", "3", etc. and "A", "B", "C", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] This embodiment provides a rotary centrally controlled multi-inlet and outlet pipeline distribution valve for a continuous adsorption and desorption separation process and a continuous adsorption and desorption process for phenol-containing wastewater in which 12 reactors are circulated in series using the rotary centrally controlled multi-inlet and outlet pipeline distribution valve, such as Figure 1-13 As shown, the continuous adsorption and desorption process for phenol-containing wastewater in this embodiment uses 12 reactors with the same structure, such as Figure 1As shown, all reactors input or output all materials including phenol-containing wastewater only through the upper and lower interfaces, and all perform unit reaction processes such as "adsorption-compression-steam blowing-pre-charging-desorption-compression-steam blowing-top filling" in a cyclic order according to the traditional fixed bed batch reaction mode. They are combined in series according to the unit reaction sequence to form an organic whole, continuously treat phenol-containing wastewater, achieve the dephenolization effect of wastewater and ensure the efficiency of adsorbent use. The key to realizing the continuous adsorption and desorption process is to centrally and synchronously transport all reaction materials including raw materials, process materials and product materials between the reactors in the reactor group and between the reactor group and the upstream and downstream supporting facilities according to a series of docking combination rules. In order to avoid complicated and cumbersome switch control point design, in this embodiment, all material pipelines entering and exiting the reactor and the connecting pipelines between the reactors are built-in "implanted" into the rotary centralized control multi-inlet and outlet pipeline distribution valve for continuous adsorption and desorption separation process. The rotary centralized control multi-inlet and outlet pipeline distribution valve serves as a transfer and transmission device between the total inlet and outlet pipelines of various materials and the interface pipelines of each reactor. The duration of independent adsorption saturation (or reaction failure) of the first-stage adsorption reactor is used as the step length, so that the reactor performing the first-stage adsorption reaction at any time will exit the operation subsequence and enter the regeneration subsequence after reaching the adsorption saturation state (that is, after the adsorption capacity is exhausted), and all other reactors are synchronized to advance step by step (that is, each reactor switches to execute the next reaction operation in the sequence). Through periodic rotation with equal time intervals and equal angle intervals, the 12 reactors are sequentially cycled through the reaction processes of "adsorption-compression-steam blowing-pre-filling-desorption-compression-steam blowing-top filling", so as to conveniently realize continuous synchronous adsorption and synchronous desorption of phenol-containing wastewater.

[0031] like Figure 3-10 As shown, the rotary centralized controlled multi-inlet and outlet pipeline distribution valve of the present application includes a rotor ring 1, a stator ring, a radial clamping device, a tangential rotation device, a control system 7, a reactor inlet and outlet pipeline cluster interface (1# to 12# upper and lower interfaces) and a material inlet and outlet pipeline cluster interface (A# to J# material interface) and other components. Among them, the stator ring includes an upper stator ring 2 and a lower stator ring 3, the radial pressing device includes an upper stator chamber 2.1, an upper piston ring 2.7, a lower stator chamber 3.1, a lower piston ring 3.5 and a compressed gas management system 6, and the tangential rotation device adopts a rotary servo motor 4; the upper stator ring 2 radially clamps the rotor ring 1, the upper stator ring 2 includes an inner ring 2.2 and an outer ring 2.3, the interface of the inner ring 2.2 of the upper stator ring is connected to the material input and output pipeline cluster, and the interface of the outer ring 2.3 of the upper stator ring is connected to the reactor input and output pipeline cluster, the tangential rotation device drives the rotor ring 1 to rotate periodically according to the time interval and radial angle set by the program, and the radial pressing device causes the pressure between the tangential fitting surfaces of the rotor ring 1 and the upper stator ring 2 to fluctuate in a pulsed manner as the rotor ring 1 rotates step by step.

[0032] The upper stator ring 2 and the lower stator ring 3 are fixedly connected to the upper stator ring skirt 2.4 and the lower stator ring skirt 3.2 with the fixing bracket 5 through fixing bolts, and the fixing bracket 5 is fixed to the building facilities through anchor bolts. Of course, the fixing bracket 5 can also be replaced by the building facilities themselves.

[0033] The rotor ring 1 is evenly arranged with penetrating rotor connecting rods 1.1. The rotor ring 1 is connected and fixed with the rotor shaft disk 1.2 through the rotor connecting rods 1.1. The rotor shaft disk 1.2 is connected and fixed with the output rotating shaft 4.1 of the rotary servo motor 4. The rotary servo motor 4 is controlled by a predetermined program of the control system 7 to drive the rotor ring 1 to rotate precisely in steps, that is, after being in place and waiting for a certain period of time, it quickly rotates a certain angle and repeats the cycle. Taking the 12 reactors in series in this embodiment as an example, the time here is calculated by the designer based on the adsorbent loading amount, saturated adsorption amount, wastewater flow rate, wastewater adsorbent concentration and effluent adsorbent concentration requirements of a single reactor. If conditions permit, it can also be determined by a fixed bed series adsorption test. In this embodiment, the rotation angle is 30°, that is, the 360° circumferential rotation angle is evenly distributed to the 12 reactors.

[0034] The ends of the upper stator chamber 2.1 and the lower stator chamber 3.1 of the inner cavity of the upper and lower stator rings are similar to single-acting piston cylinder structures. The lower part of the piston is connected to the exhaust pipe through the exhaust port 2.6 and the exhaust port 3.4. The upper compressed air interface 2.5 and the lower compressed air interface 3.3 are both connected to the three-way 6.3. The qualified compressed air processed by the three-way fitting enters the ends of the upper and lower stator ring inner cavities through the proportional air pressure regulating valve 6.1, the residual pressure release valve 6.2 and the three-way 6.3 in sequence. The control system 7 accurately controls the proportional air pressure regulating valve 6.1 and the residual pressure release valve 6.2 through a predetermined program, so that the end pressure of the upper piston ring 2.7 and the lower piston ring 3.5 on the rotor ring fluctuates in a pulsed manner as the rotor ring rotates step by step. The stator ring serves as the connection interface for all the inlet and outlet material pipelines and all the 12 reactors in the continuous adsorption and desorption process device. The rotor ring serves as the control hub for changing the docking combination between all the inlet and outlet material pipelines and all the 12 reactors in the continuous adsorption and desorption process device. Through the relative rotation of the stator ring and the rotor ring, the 12 fixed reactors are centrally driven to transform and execute different unit operations in an organized and orderly manner, thereby realizing complete and continuous process operation.

[0035] The rotor ring 1 in this embodiment is made of composite engineering plastics, such as PTFE polytetrafluoroethylene composite plastics, PEEK polyetheretherketone composite plastics, POM polyoxymethylene composite plastics, etc., to meet the requirements of acid and alkali resistance, solvent resistance, wear resistance, high elastic deformation and high dimensional stability, and better diffuse the pressure acting on the end face to the circumferential surface. When the rotor ring 1 rotates, the radial clamping device reduces the end pressure and moderately reduces the pressure on the circumferential contact surface between the rotor ring 1 and the upper stator ring 2. After the rotor ring 1 rotates into place, the radial clamping device restores the end pressure and moderately increases the pressure on the circumferential contact surface between the rotor ring 1 and the upper stator ring 2, thereby maintaining a close fit between the rotor ring 1 and the upper stator ring 2.

[0036] 24 interfaces are evenly arranged on the outer circumference of the upper stator ring outer ring 2.3, with 12 interfaces distributed in the upper and lower layers, respectively fixedly connected to the reactor inlet and outlet pipeline clusters, that is, the upper and lower interfaces 1# to 12# of the material input and output pipelines of the 12 reactors. Each reactor has an upper interface and a lower interface. The material enters the reactor from one interface and exits the reactor from the other interface. The wastewater to be adsorbed enters the reactor from the upper interface, and the desorbent enters the reactor from the lower interface. Ten interfaces are arranged at different heights on the inner circumference of the inner ring 2.2 of the sub-ring, which are fixedly connected to the material inlet and outlet pipeline clusters (i.e., the raw material input pipeline and the product material output pipeline of the adsorption and desorption reactor group as a whole from layer A to layer J), from top to bottom, including the A layer wastewater inlet, the B layer water production inlet, the C layer desorbent inlet, the D layer desorbent (reuse) inlet, the E layer compressed air inlet, the F layer low-pressure steam inlet, the G layer desorption liquid outlet, the H layer desorbent (reuse) outlet, the I layer water production outlet, and the J layer wastewater outlet.

[0037] The rotor ring 1 is engraved with a number of tangential grooves and radial channels in three dimensions, such as Figure 6 As shown (for the sake of clarity, the figure only shows the material pipelines connecting the C-layer desorbent, the D-layer desorbent reuse and the G-layer desorbent liquid, the pipelines connecting the upper and lower interfaces of the 8# to 11# reactors, and the related internal connecting pipelines), that is, a series of grooves are carved along the inner and outer circumferential surfaces, and a series of channels are carved along the radial direction. The radial channels are connected to the grooves on the inner and outer circumferential surfaces. The specific directions of the channels and grooves are as follows Figure 7 As shown, the grooves at different heights on the tangential inner circumferential surface correspond to 10 material inlet and outlet pipeline interfaces through the channels in the inner ring 2.2 of the upper stator ring; the grooves on the tangential outer circumferential surface correspond to the upper and lower interfaces of 12 adsorption and desorption reactors through the channels in the outer ring 2.3 of the upper stator ring.

[0038] The rotary central control distribution valve rotates the rotor ring 1 at equal time intervals and equal angle intervals according to Figure 2The control logic of the matching docking combination shown in the valve array control table centrally and synchronously distributes and transports all main and auxiliary raw materials, process materials and product materials required for the continuous adsorption and desorption separation process, including phenol-containing wastewater, adsorption water, desorbent and desorption liquid, among all 12 reactors in the reactor group, and between the reactor group and upstream and downstream supporting facilities.

[0039] It should be noted that the adsorbents filled in the continuous adsorption and desorption process reactor or adsorption column include resins, zeolites, activated carbon, activated coke and other materials. When different materials are used as adsorbents, the unit reaction (or unit operation) process of the continuous adsorption and desorption process may be different, but "multiple fixed-bed reactors of the same specifications connected in series cyclically traverse each unit reaction process" as the realization of the core logic of the continuous adsorption and desorption process can all be achieved using the rotary centralized controlled multi-inlet and outlet pipeline distribution valve of this application.

[0040] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical scheme and / or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical scheme of the present invention. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
