Description

A kind of simulation geological storage CO 2The cultivation case that leaks
Technical field:
The utility model relates to the crop genetics case, refer to especially a kind of can simulating plant root layer soil external source CO 2The crop genetics device of invading is mainly used in geological storage CO under the reduction of greenhouse gas discharge background 2Issuable leakage impact on agriculture evaluation studies.
Background technology:
Carbon dioxide capture and seal (Carbon Capture and Storage, be called for short CCS) up for safekeeping refers to by the carbon capture technique, the CO that industry and relevant energy industry are produced 2Separate, be transported to one and seal the place up for safekeeping, and make its process (IPCC, 2005) long-term and atmospheric isolation by the means of sealing up for safekeeping.CCS is considered to a technology emerging, that have extensive carbon emission reduction potentiality.In December, 2010, the agreement of " with the CCS of geology form as the CDM project activity " has been passed through in the United Nations's Difference on Climate Change Negotiation conference of holding in the Mexico Cancun, and admit " recognize that geology form A CS is the relevant science and technology that realizes the conference final goal, and might become one of potential means that reduce greenhouse gas emission ".Simultaneously, in December, 2011, the Global climate change conference of holding in the Durban, South Africa is again clearly with CCS technology and CDM(Clean Development Mechanism) etc. be enumerated as in the lump following global CO 2The major measure that reduces discharging, the SBSTA(subsidiary body that consult in science and technology) branch has also carried out further exploration and discussion with regard to the methodology of CCS project under CDM, is indicating that CCS will enter the fast development phase.But the risk that the CCS technology exist to be leaked will cause adverse effect to area even Global Ecological and atmospheric environment in case occur to leak.
Realize large-scale application and the project deployment of CCS technology, must understand CO 2The potential potential safety hazard that leakage may cause.Be used at present simulation geological storage CO 2Leakage mainly is divided into natural emission source and artificial these two kinds of thinkings of source of leaks to the research of agroecological environment impact.Wherein, natural CO 2Emission source mainly comprises steam type underground heat, volcano and hot-water type geothermal spring etc., yet the natural scale that affects experimental field of this class is comparatively single and narrow, can't simulate the effect that technical grade CCS seals the storehouse up for safekeeping, and experimental field before research long term exposure in high concentration CO 2In the environment, the ecosystem may have been finished adaptation and recovery process, can't assess representativeness and overall process that impact occurs.And based on the crop genetics platform of artificial leakage analogue means, can quantitatively control CO 2Leakage opportunity and degree, artificial selection subjects and scale for more research sight is provided, becomes just gradually geologize and seal CO up for safekeeping 2Leakage is on the focus of agricultural ecosystem impact.
Existing Artificial Control CO 2Leak simulation analysis and detect (artificial soil gassing and response detection from artificial soil venting and the response of Univ Nottingham UK respectively, be called for short ASGARD) and zero-emission research and technique center (zero emission research and technology center, the abbreviation ZERT) of the vertical university of Montana, United States.Univ Nottingham UK uses the CO of low temperature in the open air in the test site 2Gas cylinder guarantees the gas supply, under the control of gas flow controller, utilizes the round-meshed plastic tube in bottom of vertically laying, and underground 60cm place passes into pure CO to each center, experimental plot 2Gas in conjunction with GA2000 gas instrument, is analyzed soil CO 2/ O 2Concentration, and 0.5m*0.5m is installed on the earth's surface is that the Dreager pipe (Draeger tubes) of unit detects near surface CO 2Impact on vegetation.The horizontal pipe that the vertical university of Montana, United States has designed a long 97m is imbedded underground 2m place, and pipe ends respectively has the stainless steel protection cover of a long 12m of being respectively and 15m, and remaining 70m pipeline utilizes the natural rubber obstruct to be 6 parts and to be provided with the crack, for CO 2Even leakage.CO 2Gas source is in liquid CO 2Gas cylinder passes into underground piping with gaseous form under the control of flow quantity control instrument.The two leaks CO to further investigation 2Change in time and space near surface plays a good role.The structure thought of this type of artificial test method and based on the characteristics of reality simulation makes to have very important reference aspect its research of assessing the CCS risk of leakage in future.Yet all there is specificity in these Artificial Control tests, and leak rate is constant, single, and the diversity that may leak sight to reality considers that not, its result is difficult to comparison.
Summary of the invention:
