Abstract
A high recovery ratio pressure-variable absorption gas splitting device comprises at least two PSA apparatuses constructed by absorption tower pipes. An exhaust pipe of the PSA apparatus is provided with a branch to connect with an exhaust reclaiming tower. A control valve is also arranged in the branch. The outlet of the exhaust reclaiming tower is connected to a raw gas inlet pipe of the PSA device through a supercharger to construct an exhaust reclaiming apparatus. The utility model can deliver the reclaimable tail gas to the exhaust reclaiming tower instead of delivering the reclaimable tail gas into the air, and then supercharge and mix the accumulated exhaust into the raw gas to reclaim. The material waste is reduced, the gas extraction and recovery rate is improved, and the energy consumption and operation cost of the device are reduced.
Description
Technical field: the utility model relates to a kind of transformation adsorbed gas separation equipment.
Background technology: transformation adsorbing separation equipment commonly used when industrial gasses separate, i.e. PSA device, but the adsorption tower in the PSA device is in operation and needs the switching of cycle absorption work, reproduced state, can produce a large amount of emptying end gas.In fact many tail gas have recovery value, particularly utilize product gas blowback regeneration adsorption tower and in the tail gas that produces, available gas concentration may be higher than unstripped gas.The all direct emptying end gas of general PSA device, not only waste is big, has reduced the gas extraction rate of recovery of equipment, and the equipment operation energy consumption of making increases the raising production cost.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of recyclable high-recovery transformation adsorbed gas separation equipment that utilizes part tail gas.
The utility model comprises the PSA device that two or more adsorption tower pipeline configurations connect and compose, on the exhaust emissions pipeline of this PSA device, be provided with a branch road and be communicated with tail gas recovery tower, also be provided with control valve in this branch road, the outlet of tail gas recovery tower then is communicated with the raw material air inlet pipeline of PSA device by supercharger, constitute device for recovering tail gas.
The utility model can will have the tail gas of the value recycled to send into tail gas recovery tower and not emptying, then the tail gas supercharging of accumulating is mixed in the unstripped gas and recycles, significantly reduce wastage of material, improved the gas extraction rate of recovery of equipment, and reduced equipment energy consumption and operating cost.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is the structural representation of embodiment.
Embodiment: as shown in the figure, on the exhaust emissions pipeline 3 of the PSA device 1 that two adsorption tower pipeline configurations connect and compose, be provided with a branch road and be communicated with tail gas recovery tower 2, also be provided with control valve 4 in this branch road, the outlet of tail gas recovery tower 2 then is communicated with the raw material air inlet pipeline 6 of PSA device 1 by supercharger 5, constitute device for recovering tail gas.The PSA device can for two towers, three towers or more multitower count classification type, present embodiment adopts two common adsorption tower structures.
During work, if tail gas has recovery value, open control valve 4, tail gas enters in the tail gas recovery tower 2 to be stored, and accumulation is after supercharger 5 supercharging loopbacks are gone in the raw material air inlet pipeline 6 is recyclable use.If do not need to reclaim, then can closed control valve 4 emptying.In practice, the unstripped gas of PSA device 1 was generally all wanted supercharging before sending into.Therefore, supercharger 5 is set is external device, air inlet connects the raw material source of the gas simultaneously, the supercharging of unstripped gas and tail gas can be mixed on a supercharger 5 like this and carry out, and reduces equipment cost.
