Description
Technical Field
The invention relates to a gas treatment device, in particular to a gas treatment device for treating organic waste gas pollutants by a catalytic method or an adsorption concentration method.
Background
Patent document CN110772927a discloses a gas adsorption concentration device composed of a plurality of parallel adsorption units and a set of moving hot air regeneration device. The active effect is to convert the regeneration process of the regeneration type fixed bed adsorber from the centralized regeneration requiring high power energy consumption into the step-by-step regeneration with low power energy consumption, and to fully utilize the heat energy in the regeneration process by using two adsorption units to be connected in series to recover the heat absorbed by the adsorbent and using the mode of heat exchange between gases to recover the heat in the discharged regeneration gas. The mobile regeneration device consists of a hot air regeneration device and a mechanical movement device. The hot air regenerating device is characterized in that the head end of one side of an adsorption unit group consisting of two adsorption units is communicated with a regeneration gas supply device and a regeneration gas treatment device through flexible pipelines respectively, the part of the hot air regenerating device is called an IO end, and the head ends of the other side of the adsorption unit group are communicated through a pipeline containing a gas heating device and are called CA ends. The regeneration gas from the regeneration gas supply device passes through the two adsorption units of the adsorption unit group in sequence, and reaches the regeneration gas treatment device. The mechanical moving device supports the hot air regenerating device and is driven by controlled power to sequentially complete the connection and switching of the regenerating device and each adsorption unit group.
In practice, the mechanical moving device sequentially completes the connection and switching processes of the IO end, the CA end and each adsorption unit group, and needs to support the transverse movement, the vertical movement and the rotation of the IO end and the CA end, and at least 8 controlled movements of the IO end, the CA end and the adsorption unit at two sides, such as the combination and the separation. These controlled motion complexities and manufacturing control accuracies make the device expensive to manufacture. Operational reliability poses a fairly rigorous challenge to the manufacture and operational maintenance of the device.
Disclosure of Invention
The invention makes the mechanical structure and control mode transformation for the mechanical moving device of the technical proposal, and upgrades the regeneration process mechanism. The number of controlled movements is reduced, the movement control mode is simplified, the equipment cost is reduced, and the equipment operation reliability is enhanced.
The device can also be used for treating organic pollution gas by a normal-temperature catalysis method. When the organic pollution gas passes through the device, the organic pollution gas is generated by the catalytic action of the catalyst and is nontoxic and harmless or low in toxic substance to be discharged. The dosage form and filling mode of the catalyst are the same as or similar to those of the adsorbent, and the catalytic action process is similar to that of the adsorption process. The contaminants do not substantially reside in the catalyst for a long time, but the catalytically acting contaminants themselves or accompanying other harmful substances can cause deactivation of the catalyst. This deactivation can be accomplished by heating to remove the detrimental species from the catalyst and to substantially restore the original catalytic activity of the catalyst. The process of catalyst heating to restore catalytic activity is similar to the process of adsorbent regeneration to restore adsorption activity, and the two processes can be collectively referred to as regeneration. The corresponding catalytic and adsorption processes for the pollutant gases are collectively referred to as treatment processes. The harmful gas generated by the regeneration of the adsorbent and the regeneration of the catalyst can be treated by adopting a similar treatment process basically. The contaminated gas is referred to herein as a working gas or working gas and the regeneration or regeneration treatment gas is referred to as a regeneration gas or regeneration gas.

The rectangular array is an operation command by drawing software, wherein the meaning of "class" means that the overall arrangement mode is mainly emphasized, and the number of individuals contained in each row and each column is not always strictly the same, such as an individual vacancy at the middle part or an individual vacancy at the position of four corners intentionally formed for functional design. The rotary regeneration device consists of a regeneration gas supply device, a regeneration gas heating device and a rotary butt joint device. The rotary butt joint device comprises a regeneration gas A side rotary butt joint, a processing unit air inlet and outlet conversion device and a regeneration gas B side rotary butt joint. The air inlet and outlet switching device of the processing unit has the function that the air inlet and outlet of the processing units arranged in a similar rectangular array mode are communicated into two circular tracks which are respectively and uniformly arranged and correspond to the rotary butt joints at the two sides of A, B. The specific scheme can be that a plurality of pipelines with different lengths and shapes are provided, one end of each pipeline is communicated with the air inlet and outlet end of the processing unit, and the other end of each pipeline is sequentially opened in two circular tracks corresponding to the rotary butt joints on the two sides of A, B. Furthermore, the pipeline openings in the two circular tracks can be connected into a whole by a circular disc. The two side rotary butt joints can rotate synchronously through mechanical connection. In the regeneration process, the treatment agent of the regeneration group working unit comprising at least one working unit is heated and regenerated by the regeneration gas from the regeneration gas supply device, and meanwhile, the heat absorbed by the treatment agent of the heat recovery group working unit comprising at least one working unit in the regeneration process is recovered and the working unit group is cooled. The regeneration gas heating devices are embedded in the rotary butt joint devices at the two sides, and the connection and the switching between the regeneration devices and each working unit group are completed through the separation, rotation and butt joint actions under the drive of controlled power.
The regeneration and heat recovery banks may include only one working unit.
When the regeneration group comprises more than two working units, the exhaust gas concentration rate of the device in the regeneration process can be improved, and the heat utilization efficiency of the device in the regeneration process can also be improved.

The flow direction of the regeneration gas in the regeneration process can be optimized through connecting pipelines connected to the two sides of the AB, and the cooling effect can be realized by full-concurrent regeneration or regeneration.
Can be with regeneration gas heating function through the pipeline migration put to the peripheral hardware RTO device of handling regeneration gas in, when handling the polluted gas who contains the VOCs composition of more calorific value, be used for heating regeneration gas with the unnecessary heat that the VOCs pyrolysis produced.

The working units 21 are small fixed bed adsorbers, and all the working units are arranged in a quasi-rectangular array and connected by the support connecting structure 22 to form a closed adsorption core 2, so that the working gas entering the shell from the working gas inlet must pass through the working units 21 on the core 2 to reach the working gas outlet.
See fig. 1 and fig. 2A-2B. The rotary regeneration device 3 comprises a regeneration air supply device 31, a rotary butt joint device 32 and a regeneration gas heating device 33. The regeneration gas supply device 31 includes an air filter device 311 and a regeneration fan 312. The rotary docking device 32 includes a regeneration gas a-side rotary docking head 321A, a regeneration gas a-side branching connection device 322A, a regeneration gas B-side branching connection device 322B, and a regeneration gas B-side rotary docking head 321B. The two-side rotary butt joint is connected and synchronously rotates through a connecting shaft 34. The regeneration gas a side branch connecting device 322A and the regeneration gas B side branch connecting device 322B each include a docking disk 3221A, 3221B, each docking disk is provided with 24 docking ports 32211A, 32211B, and each docking port is respectively communicated with the air inlet/outlet 211A, 211B of the corresponding working unit through the respective branch connecting tube 3222A, 3222B. The regeneration gas supply device 31 and the additional gas processing device 9 are connected to the regeneration gas a side rotary joint 321A by a coaxial rotary joint 323. Here, the regeneration gas treatment device 9 is, for example, an RTO, and belongs to peripheral equipment of a modular rotary docking gas treatment device.
Here, the use of adsorption treatment is taken as an example. During the adsorption operation, the regeneration gas a-side rotary joint 321A and the regeneration gas B-side rotary joint 321B are disengaged from the corresponding joint disks 3221A and 3221B. Working gas enters the static pressure box 111A in the shell 11 through the working gas inlet 12, parallelly enters 24 working units 21 through the regenerated gas A side branch connecting device 322A, passes through the treating agent filler layer 212 in the working units, pollutants are retained in the treating agent, clean working gas leaves the working units 21, enters the collecting box 111B through the regenerated gas B side branch connecting device 322B, and finally is discharged out of the whole device from the working gas outlet 13, so that the adsorption process is completed.
During regeneration operation, the regeneration gas enters the heat recovery group working unit through the air filter device 311, the regeneration fan 312, the coaxial rotary joint 323A, the regeneration gas a side rotary butt joint 321A and the regeneration gas a side branch connecting device 322A, is preheated by the filler 212 in the heat recovery group working unit, enters the regeneration gas B side branch connecting device 322B, enters the regeneration group working unit through the regeneration gas B side rotary butt joint 321B and the regeneration gas heating device 33 embedded therein, enters the regeneration group working unit through the other connecting pipeline of the regeneration gas B side branch connecting device 322B again, heats and regenerates the treating agent filler 212 in the regeneration group working unit, carries the removed pollutant to enter the regeneration gas a side branch connecting device 322A and the regeneration gas a side rotary butt joint 321A again, and is discharged to the regeneration gas treatment device 9 through the coaxial rotary joint 323A.
The regeneration gas completes the heating regeneration of the treating agent of the regeneration group working unit, and simultaneously recovers the heat absorbed by the treating agent of the heat recovery group working unit in the regeneration process and cools the working unit group. The rotary butt joints 321A and 321B on both sides are driven by controlled power to complete the connection and switching between the rotary regeneration device 3 and each working unit group through the actions of disengagement, rotation and butt joint. The B-side rotary butt joint 321B is connected to and supports the regeneration gas heating device 33, and the regeneration gas heating device 33 and the B-side rotary butt joint 321B move synchronously.
Example 2The modular rotary butt-joint gas treatment device is improved, and a resistance-reducing valve is added, and the resistance-reducing valve is shown in attached figures 3 and 7.
On the basis of embodiment 1, in order to reduce air resistance when the working gas passes through the regeneration gas branch connecting devices 322A and 322B at two sides of A, B during the adsorption operation and reduce air flow imbalance caused by connecting pipelines with different lengths corresponding to each working unit, a drag reduction valve 3223A and 3223B is arranged at an inlet and an outlet of each working unit. The valve is controlled to close during the regeneration operation of the corresponding working unit and to open at other times.
The control of the resistance reducing valves can be respectively controlled by a master controller, and two valves corresponding to each adsorption unit are used as a group and can be used as a control point for synchronous control.
The better control mode of the resistance-reducing valve is to synchronize the opening and closing actions of the valve with the mechanical device with the separating-rotating-butting action of the rotating butt joints 321A and 321B at the two sides, so that the resistance-reducing valve can be controlled without adding a separate control point. Specific embodiments of this control scheme are described in detail in the examples that follow.
Example 3The improvement of the modular rotary docking gas treatment device shown in embodiment 2 realizes advanced regeneration and advanced heat recovery functions, and a cooling effect priority mode, which are shown in fig. 4, 5A-5B, 6-7, 8A, 8B and 9.
The regeneration group and the heat recovery group are both provided with two working units, a connecting pipeline 3224 which can synchronously rotate and stretch with the regeneration group and the heat recovery group is arranged between the two rotary butt joints 321A and 321B, and the connecting pipeline 3224 can stretch and contract by adopting a corrugated pipe expansion joint or a sealed telescopic sleeve. See fig. 4, 6-7.
The manner in which drag reduction valves 3223A and 3223B are controlled is described in detail herein. See fig. 8A-8B, fig. 9.
In this embodiment each step of the regeneration operation involves 4 work units, for a total of 8 drag reduction valves. The 8 resistance-reducing valves need to complete the closing action of the resistance-reducing valves while the rotating docking heads 321A and 321B complete the docking of the docking ports corresponding to the docking discs 3221A and 3221B.
The mechanical transmission device for synchronizing the opening and closing actions of the drag reduction valves 3223A and 3223B with the mechanical device of the separation-rotation-butt action of the rotating butt joints 321A and 321B at the two sides adopts a power transmission line 3225 in the embodiment. The opening and closing of the drag reduction valve is completed by a T-shaped rocker 3226, the stretching action transmitted by a power transmission line is converted into the rotating motion of the drag reduction valve by a plane hinge four-bar mechanism comprising another rocker 3227, a connecting rod 3228 and a rack 3239, and a boosting transmission mechanism acting when the valve is closed is formed by utilizing a dead point, so that the valve is pressurized and sealed. Alternatively, the transmission function of the power transmission line 3225 may also be implemented by other common mechanical transmission means, such as a connecting rod, a pull wire, a flexible transmission shaft, etc. The housing 3239 is here represented by two ground connection faces.
Referring to FIG. 9, more specifically, the pivot point of the T-shaped rocker arm connected with the drag reduction valve is O 2 At O in 2 A return spring 32291 is arranged at the position, and the rotation fulcrum of the rocker 3227 is O 1 A return spring 32292 is also provided. The connecting rod 3228 is connected to the two rockers via two revolute pairs, and has two rotation pivots O 1 And O 2 Forming a frame of a plane hinge four-bar mechanism. Curve O 1 AB shows the valve in open state, straight line O 1 A 'B' shows that the plane hinge four-bar mechanism is in a dead point state, and the valve is in a stress application closing state.
Example 4Another implementation of the modular rotary docking gas treatment device shown in example 3, either the regeneration depth first mode or the full forward flow mode, is shown in fig. 10.
On the basis of embodiment 3, the connection mode of the two rotary butt joints 321A and 321B and the synchronous rotation selecting connection pipeline 3224 is adjusted, so that the airflow directions of the regeneration gas in the regeneration group working unit and the heat recovery group working unit are kept consistent.
The modular rotary docking gas treatment apparatus of the present embodiments has particularly significant technical advantages when used to treat compositions containing relatively high concentrations of VOCs. The device realizes advanced regeneration and advanced heat recovery functions which can further improve the concentration ratio of waste gas and further reduce the consumption of regeneration heat energy. This configuration allows the regeneration gas to be in a low temperature state when exiting the gas treatment device and entering the RTO device.
Example 5Module as in example 3The improvement of the rotary butt joint gas treatment device increases the function of utilizing RTO waste heat as a heat source of regenerated gas, and refer to the attached figure 11.
On the basis of embodiment 3, another coaxial rotary joint 323B is added on the side B of the apparatus, the regeneration gas preheated by the heat recovery group operation unit is introduced into the RTO through two pipelines, the excess heat generated by pyrolysis of the regeneration gas by the RTO except for maintaining the self heat balance of the RTO is utilized to heat the regeneration gas, and then the regeneration gas is sent to the regeneration group operation unit through a pipeline.
