Abstract
The utility model discloses a desulfurizing agent regeneration device of a carbon dioxide recovering system. The desulfurizing agent regeneration device comprises two parallel desulfurizing towers and two parallel drying towers, wherein one of the two desulfurizing towers and two drying towers is operating and the other one is standby, the desulfurizing agent regeneration device is characterized in that a regeneration gas outlet of each drying tower is connected with the bottom of each desulfurizing tower by a pipe, regeneration gas in which originally-regenerated desiccating agent is emptied is led in the bottom of the desulfurizing tower, desulfurizing agent is regenerated while the desiccating agent is regenerated, a temperature control device is arranged at a regeneration gas outlet of each drying tower in regeneration, the desulfurizing agent is led into the bottom of the desulfurizing tower for purging until the regeneration in the drying tower is finished when the temperature of the outlet achieves more than 60 DEG C. The regeneration gas in the drying towers is fully utilized, regeneration in the desulfurizing tower can be conducted without addition of equipment, the regeneration gas can effectively purge and eliminate water adsorbed by the desulfurizing agent and adsorbed sulfur content by utilizing the temperature of 60-120 DEG C, thereby achieving the purpose of prolonging the service life of the desulfurizing agent.
Description
Technical field
The utility model relates to a kind of regenerating unit, particularly a kind of desulfurizer regeneration device of carbon dioxide recovery system, in accordance.
Background technology
At present, the desulfurizing agent in a lot of carbon dioxide recovering apparatus is not regenerated, normal operation be acticarbon, the absorption of isoreactivity charcoal is saturated like this, the desulfurizing agent life-span has also arrived, must replacing.The frequent desulfurizing agent is wasted time and energy like this, causes whole production cost higher all at 6 months to 18 months service life for general device desulfurizing agent.In order to prolong the service life of desulfurizing agent, the method that desulfurizing agent in the partial CO 2 retracting device generally can adopt air to blow is regenerated, this system is comparatively common in the device of the exquisite carbon dioxide of recovered alcohol factory tail gas, utilize air blast that air is blown in the desulfurizing tower, process continues several hours.This scheme, needing to add in addition blower equipment wastes again electricity, and effect is also unsatisfactory; Because generally all before drying section, the free water in the carbon dioxide also can be desulfurized agent absorption in desulfurization workshop section, caused in the desulfurizing tower moisture more, be unfavorable for finally H
2The normal air blowback is used in the absorption of S, and the free water that desulfurizing agent is adsorbed is partly blown down, but general effect is not fine, and simultaneously normal air blowback also is unfavorable for blowing out of the interior sulphur content that adsorbs of desulfurizing agent owing to temperature is low.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome the defective in the above-mentioned background technology, to provide a kind of and transform at original carbon dioxide recovery plant, do not add new equipment, do not increase manufacturing cost, have advantages of simultaneously large-minded, temperature is controlled.
The scheme of the utility model technical solution problem is: comprise desulfurizing tower and drying tower, desulfurizing tower cat head and drying tower cat head are connected with the pipeline with control valve, the regeneration gas outlet of described drying tower links to each other with at the bottom of the desulfurizing tower tower by pipeline, this pipeline is provided with control valve, and the regeneration gas exit also is provided with an attemperating unit.
Described desulfurizing tower is the desulfurizing tower of two parallel connections, and described drying tower is the drying tower of two parallel connections.
The beneficial effects of the utility model are: the regeneration gas of emptying is introduced the desulfurizing tower bottom behind the drier of will originally regenerating, while recycling desulfurizer during each desiccant regeneration, in the outlet of drying tower regeneration gas one attemperating unit is set during regeneration, regeneration gas is comparatively dry when outlet temperature reaches more than 60 ℃, be introduced into the desulfurizing tower bottom this moment, purge until the drying tower regeneration ending.Take full advantage of the drying tower regeneration gas, need not add equipment and just can carry out desulfurizing tower regeneration, the drying tower regeneration gas is utilized its temperature of 60～120 ℃ simultaneously, can effectively blow down the moisture of absorption in the desulfurizing agent and the sulfur that has adsorbed, and reaches to prolong the desulfurizing agent purpose in service life.

The specific embodiment
The utility model as shown in Figure 1 comprises drying tower (8) and the drying tower for subsequent use (81) of two parallel connections, the desulfurizing tower of two parallel connections (7) and desulfurizing tower for subsequent use (71), industrial carbon dioxide air inlet (1) enters the bottom of desulfurizing tower (7) and desulfurizing tower for subsequent use (71) by the road, desulfurizing tower and desulfurizing tower for subsequent use top are provided with desulfurization drain (5), drying tower (8) and drying tower for subsequent use (81) bottom are connected to the outlet (2) that gas goes to next workshop section, and drying tower and drying tower for subsequent use top are provided with dry drain (4).
During normal operation, desulfurizing tower and drying tower are out that all one is standby, suppose that desulfurizing tower (7) and drying tower (8) work, during regeneration, we open control ball valve (V1, V3, V5) first with desulfurizing tower for subsequent use (71) and drying tower for subsequent use (81) pressure release, and all the other Regeneration control valves are closed condition, pass into regeneration gas, regeneration gas is dry CO
2, with good conditionsily can use N
2Its better effects if is warming up to 200 ℃ through electric furnace, and process drying tower for subsequent use (81) is desiccant regeneration wherein, and its regeneration outlet temperature is closed electric furnace after 30 ℃ of normal temperature rise to 120 ℃, use normal temperature CO
2Or N
2The drying tower outlet temperature blown to 30 ℃ of whole regenerative processes in the left and right sides of normal temperature namely finish.Because the initial stage regeneration gas carries a large amount of water through drying tower in the regenerative process, if it is unfavorable to desulfurizing agent to enter desulfurizing tower, so we wait for that drying tower regeneration outlet temperature reaches more than 60 ℃, it is the temperature of attemperating unit (6) test, the interior moisture of drying tower this moment seldom, impact on desulfurizing agent can have been ignored, open successively control ball valve (V6, V7, V9), regeneration gas is introduced desulfurizing tower, then slowly close V5, regulate tolerance to one a suitable degree, keep in general regeneration gas pressure at 0.07 ~ 0.1MPa.Whole purge probably continues 5-6 hour, and the cycle is 48 hours.When the work of desulfurizing tower (71) and drying tower for subsequent use (81), regenerative sulfur binding tower (7) during with drying tower (8) process also be the same.Facts have proved, it can effectively prolong desulfurizing agent 3-6 in service life month.
