Description
Technical Field
The invention relates to a gas treatment device, in particular to a 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 one end of an adsorption unit group consisting of two adsorption units is respectively communicated with a regenerated gas supply device and a regenerated gas treatment device through flexible pipelines, the part of the hot air regenerating device is called an IO end, and the other end of the adsorption unit group is communicated with two ends of a pipeline containing a gas heating device and is called a CA end. 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 manufacturing cost of the device prohibitive. Operational reliability poses a fairly rigorous challenge to the manufacture and operational maintenance of the device.
Disclosure of Invention
The invention improves the mechanical structure and the control mode of the mechanical moving device in the technical scheme. 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 catalysis process is similar to the adsorption process. The contaminants do not substantially reside in the catalyst for a long time, but the catalytically acting contaminants themselves or other accompanying trace 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 specific technical scheme of the invention is as follows: a gas processing device comprises a shell, a working gas inlet, a working gas outlet, a plurality of working units and a set of rotary regeneration device. The working units are equivalent to a small fixed bed adsorber, all the working units are arranged in a rectangular array mode and are connected into a closed working core by a supporting and connecting structure, so that working gas entering the shell from the working gas inlet can reach the working gas discharge port only by passing through the working units on the core. The rectangular array here is an operation command by drawing software. In the regeneration process, the regeneration gas from the regeneration gas supply device completes the heating regeneration of the treating agent of the regeneration working unit, and simultaneously recovers the heat absorbed by the treating agent of the heat recovery working unit in the regeneration process and cools the working unit. The rotary butt joint device is embedded with a regeneration gas heating device and completes the connection and switching of the regeneration device and each working unit through the actions of separation, rotation and butt joint under the drive of controlled power.
When the scheme is realized, the positions of the air inlets and the air outlets of the processing units at different positions can be set, so that the air inlets and the air outlets of all the processing units arranged in a matrix are respectively and uniformly distributed in two circular tracks, and the rotary butt-joint devices at two sides can synchronously rotate through mechanical connection and butt-joint and separate from the rotary regeneration devices and the processing units when the regeneration processing is completed through axial telescopic action.
The processing unit can be set into a cuboid shape, the processing agent adopts a granular formulation, the space in the processing unit is divided into an upper gas channel, a filling chamber and a lower gas channel from top to bottom by two layers of sieve plates, and the filling agent is filled in the filling chamber. During the treatment operation, the working gas passes through the filling chamber from bottom to top. During regeneration operation, the regeneration gas passes through the packing chamber from top to bottom.
The shells of all the processing units, including the air inlet and the air outlet, are set to be in the same structure, the number of the processing units is 6 or 8, the processing units are arranged in a 2 x 3 or 2 x 4 mode, and the conversion between the forms of the shells in the same structure corresponding to different positions is realized through the vertical, left and right and front and back rotary arrangement in the mutually vertical direction. This can save the number of molds used for the molding process of the processing unit in mass production.
The positive effects of the invention include: compared with the prior parallel tubular gas adsorption concentration device, the mechanical structure and the control mode of the mobile desorption device are simplified. The rotating shaft mechanical driving device can be arranged outside the gas circuit, and can avoid the corrosion of high-humidity high-temperature gas in the waste gas environment.
The invention is further illustrated by the following figures and examples.
