Technical field
The utility model relates to a kind of absorption tower, particularly a kind of rectification carbon trapping absorption tower.
Background technology
The earth environment that the mankind depend on for existence in the positive serious threat of greenhouse effects, and the key of whole world reply greenhouse effects reduces greenhouse gas emission, wherein mainly reduces the CO2 emission of energy-consuming.According to EIA " world energy outlook 2013 ", coal demand amplification is that in variety of energy sources, amplification is maximum, and from 2007 to the year two thousand thirty, coal demand is by rising about 64%; Therefore, in the world, reducing the CO2 emission caused due to consumption of coal is one of main path controlling its total release.2009, the CO2 emissions that AND ENERGY RESOURCES CONSUMPTION IN CHINA produces exceed the U.S. became global first CO2 emission state.The situation that China's CO2 emissions comparatively fast increase, will more and more be subject to concern and the pressure of international community.In China, coal-burning power plant's CO2 emission is one of primary discharge source of greenhouse gases, and its CO2 emission accounts for 50% of China's CO2 emission total amount; And by 2010, China's Thermal generation unit was increased to 700,000,000 kilowatts, coal for power generation will reach 1,600,000,000 tons, and from 2010 years to the year two thousand twenty, national consumption of coal total amount is also by sustainable growth.Therefore, coal-burning power plant's CO2 emission is reduced most important for control China CO2 emission total amount.
At present, the technology main flow of carbon dioxide eliminating process is broadly divided into three major types: solvent absorption, membrane separation process and solid absorbent absorption method.Wherein, solvent absorption technology is the most attractive, application also the most a kind of isolation technics, and most coal-fired plant flue gas absorption unit of dioxide carbon all have employed such technology.Solvent absorption technology can also be divided into many groups, great majority are comparative maturity all, but higher energy consumption prevents the popularization of collecting carbonic anhydride technology, and carbon trapping absorption tower improvement reduce just coal-fired plant flue gas carbon dioxide absorption technique overall energy consumption important channel.
In known coal-fired plant flue gas carbon dioxide capture device, absorption tower adopts packed tower usually, arranges structured packing or dumped packing in tower body, and it is abundant that this type of turriform has mass transfer, capture rate advantages of higher.But due to the relation of packing layer, the resistance on absorption tower is comparatively large, energy consumption is high and there is the possibility of general tower.Therefore, develop a kind of lower resistance, low energy consumption, the carbon dioxide absorption tower that can prevent general tower from endangering seem particularly important.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of rectification carbon to trap absorption tower, can reduce absorption tower resistance, and effectively reduce the possibility of the general tower in absorption tower under the prerequisite not affecting absorption tower mass transfer ability.
Rectification carbon trapping absorption tower of the present utility model, comprise the tower body being provided with gas approach and exhanst gas outlet, described tower body inner chamber is provided with packing section and the spray equipment for spray-absorption agent, described gas approach is positioned at below packing section, described exhanst gas outlet is positioned at above spray equipment, is provided with fairing between described spray equipment and packing section.
Further, described fairing is the metallic plate having through hole.
Further, the thickness of described metallic plate is 3-7mm, and percent opening is 30%-70%.
Further, the distance between described fairing and packing section is greater than 1.0m, and the distance between described fairing and spray equipment is greater than 0.5m.
Further, described spray equipment comprises the shower stretching into tower body inner chamber, is provided with absorbent outlet in the bottom of described tower body.
Further, be provided with rinsing module between described spray equipment and exhanst gas outlet, described rinsing module comprises flushing pipe and the flushing water entrance be located on tower body and flushing water outlet, and flushing water flows into flushing pipe from flushing water entrance and flows out from flushing water outlet.
Further, described packing section comprises the first packing section and the second packing section that set gradually from top to bottom, and described first packing section is located in the middle part of tower body, and described gas approach is positioned at below the second packing section.
The beneficial effects of the utility model: rectification carbon trapping absorption tower of the present utility model, in tower body inner chamber, flue gas moves from bottom to top, absorbent moves from bottom to top, owing to having set up fairing, at fairing place, gas-liquid fully contacts and mass transfer, to reach or close to the effect of packing layer mass transfer, thus the overall mass transfer ability on absorption tower can be kept when reducing packing layer; And fairing resistance is low, reduce the overall resistance on absorption tower; Fairing makes tower body inner chamber have sufficient space simultaneously, effectively reduces the possibility of the general tower in absorption tower.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of fairing of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, Fig. 2 is the structural representation of fairing of the present utility model, as shown in the figure: the rectification carbon trapping absorption tower of the present embodiment, comprise the tower body 1 being provided with gas approach 11 and exhanst gas outlet 12, described tower body 1 inner chamber is provided with packing section and the spray equipment for spray-absorption agent, described gas approach 11 is positioned at below packing section, and described exhanst gas outlet 12 is positioned at above spray equipment, is provided with fairing 4 between described spray equipment and packing section; Absorption tower is packed tower structure, and the improvements on this absorption tower are just to eliminate traditional top packing layer, replace and arrange a fairing 4; Described fairing 4 can for having the metallic plate of through hole, and through hole is preferably circular hole, can make the uniform gas-liquid distribution passed through; The thickness of described metallic plate can be 3-7mm, and percent opening can be 30%-70%; Distance (distance herein refers to the distance between fairing 4 bottom surface and packing section end face) between fairing 4 and packing section is greater than 1.0m, distance (distance herein refers to the distance between fairing 4 end face and spray equipment bottom surface) between described fairing 4 and spray equipment is greater than 0.5m, now at least reduces the packing layer of 1.5m; In tower body 1 inner chamber, flue gas moves from bottom to top, absorbent moves from bottom to top, owing to having set up fairing 4, at fairing 4 place, gas-liquid fully contacts and mass transfer, to reach or close to the effect of packing layer mass transfer, thus the overall mass transfer ability on absorption tower can be kept when reducing packing layer; And fairing 4 resistance is low, reduce the overall resistance (about 10%) on absorption tower; Fairing 4 makes tower body 1 inner chamber have sufficient space simultaneously, effectively reduces the possibility of the general tower in absorption tower.
