Description

Adsorber for waste gas desorption treatment

Technical Field

The utility model relates to an organic waste gas handles the field, especially relates to an adsorber that is used for waste gas to take off adsorption treatment.

Background

As is well known, the VOC treatment process of adsorption concentration and catalytic combustion is widely applied to the treatment of low-concentration and high-air-volume organic waste gas due to simple and feasible technology and low operation cost. Currently, the adsorption concentration unit mainly adopts activated carbon adsorption.

There are three main forms of activated carbon used for adsorption: activated carbon particles, honeycomb activated carbon and activated carbon fibers. Although the honeycomb activated carbon and the activated carbon fiber have many advantages, the honeycomb activated carbon and the activated carbon fiber are still not widely applied at present mainly because of higher price. The honeycomb activated carbon has the same adsorption performance, the price of the honeycomb activated carbon is 2-3 times that of the granular activated carbon, and the price of the activated carbon fiber is 7-10 times that of the granular activated carbon.

Adsorbers currently generally take two forms: drawer type and cylinder type. Due to the structural limitation of the drawer type activated carbon adsorption box, the occupied space volume is large, and the drawer type activated carbon adsorption box is generally used for the working condition that the air quantity is not large. If the treated air volume exceeds 10000m³And h, ensuring enough filling amount, the volume is too large, the economical efficiency is greatly reduced, and in the case, short flow is easily caused, so that the saturation degree of the activated carbon layer is not uniform, and the absorption efficiency is reduced. Later, vertical cylindrical activated carbon adsorption columns were developed. The structure form of traditional packed tower has been used for reference to it, adopts the structure form of multilayer active carbon filler series connection, though the problem that area is big has been solved in part, nevertheless has the resistance loss big, the difficult shortcoming of changing of active carbon granule. The structure of the cylindrical vertical adsorber which exists simultaneously adopts the cylindrical filter layer with the annular cross section, although the problem of large resistance loss is partially solved by the structural form, under the condition of large filling amount, activated carbon particles can be accumulated in the filter cylinder to easily cause the hardening and compaction of bottom activated carbon, the saturation of the activated carbon adsorption layer can also be uneven, and the cylindrical vertical adsorber is not easy to be more easily usedThe disadvantage of replacing the activated carbon.

The adsorption/desorption unit of the adsorption concentration and catalytic combustion VOC treatment complete device adopts a plurality of (generally 3-6) activated carbon adsorption boxes connected in parallel to meet the requirement of online desorption. In this case, the above-mentioned structural style generally adopts an independent desorption pipeline, and the desorption air pipeline is parallel to the adsorption air pipeline, and the process structure is more complicated and the operation and maintenance are inconvenient. In addition, the defects of large occupied area and high cost of the structure form are more prominent for a plurality of structures connected in parallel.
