Abstract
The invention relates to a mercury removal method of a mercury-containing rock core; putting the mercury-containing rock core into a quartz tube, putting the quartz tube into a tube furnace, wherein the open end of the quartz tube extends out of the tube furnace, connecting the open end of the quartz tube with the air inlet of a condenser, connecting a condensed water inlet pipe of the condenser with a tap water pipe, vertically arranging the condenser, connecting an air outlet with the air inlet of a vacuum pump at the upper part, and connecting a collecting port with a collecting bottle at the lower part; after the connection is finished, a condensed water inlet pipe of the condenser is opened, a vacuum pump is started, the temperature point of the tube furnace is set to be 629.88K, heating is carried out, liquid mercury in the rock core is gradually gasified under the action of heat energy and vacuum, mercury vapor which is continuously evaporated enters the condenser under the action of vacuum, the liquid mercury is condensed in the condenser to be liquid mercury, and the liquid mercury flows into a collecting bottle along the inner wall of the condenser through a collecting port under the action of gravity; the method realizes the mercury-free treatment of the mercury-containing rock core, and the collected mercury can be reused.
Description
Technical field:
The present invention relates to a kind of method for removing hydrargyrum of mercurous rock core, the mercurous rock core that can produce oil play exploration and development experiment carries out mercuryless processing, can reduce mercury emissions, avoids mercury pollution.
Background technology:
In the research mesopore of reservoir of oil and gas structure, be the core of microphysics research, the topmost method of study of rocks pore structure is to determine the quantitative performance of pore constriction by the method for measuring capillary pressure at present.What the method for mensuration rock capillary pressure curve was a lot of but at present the most frequently used mainly contains three kinds: semi-permeable plate method, mercury injection method and centrifugal process.
We are to pressing the mercurous rock core after mercury is tested not do any processing at present, directly be stacked at outdoor, mercury in rock core also can evaporate gradually and form mercury vapour and cause mercury pollution like this, is therefore pressed the mercuryless processing of mercurous rock core after mercury can reduce mercury emissions, avoids mercury pollution.
Summary of the invention
The method for removing hydrargyrum that the purpose of this invention is to provide a kind of mercurous rock core, realize the mercuryless processing of mercurous rock core, and the rock core after processing can be processed by normal rock core, and collecting the mercury obtained can recycle.
The method for removing hydrargyrum of mercurous rock core of the present invention is to carry out in a device be comprised of tube furnace, quartz ampoule, condenser, receiving flask and vavuum pump; Quartz ampoule one end opening, openend is connected with glass tube with the condenser air inlet; The condensed water water inlet pipe of condenser is connected with rubber tube with running water pipe; The condenser outlet pipe passes to sewer with rubber tube; The collection mouth of receiving flask and condenser joins; The gas outlet of condenser is connected with rubber tube with air-inlet of vacuum pump.
A plurality of cylindrical mercurous rock cores are put into to quartz ampoule successively, again quartz ampoule is put into to tube furnace, the openend of quartz ampoule extends to outside tube furnace, the quartz ampoule part that extends to the tube furnace outer end does not comprise mercurous rock core, then the quartz ampoule openend is connected with rubber tube with the condenser air inlet, the condensed water water inlet pipe of condenser and running water pipe with rubber tube be connected, the condenser outlet pipe passes to sewer with rubber tube, condenser is vertically placed, gas outlet is upper, collect mouthful below, the collection mouth of receiving flask and condenser joins; The gas outlet of condenser is connected with rubber tube with air-inlet of vacuum pump.
Open the running water switch of the condensed water water inlet pipe of condenser after having connected, open vavuum pump, set the temperature spot (higher than the boiling point of mercury: 629.88K(356.73 ℃)) of tube furnace, the switch of opening tube furnace is heated.
Liquid mercury under the effect of heat energy and vacuum in rock core gasifies gradually, and then be evaporated from the rock core body, the mercury vapour constantly evaporated advances people's condenser under the effect of vacuum, because the fusing point of mercury is 234.32K(-38.83 ℃), so mercury is condensed into liquid mercury in condenser, under Action of Gravity Field, liquid mercury flows into a receiving flask along the condenser inwall through collecting mouth.
Stop heating after certain hour, close vavuum pump, close running water switch after tube furnace naturally cools to room temperature, take off the rubber tube of quartz ampoule openend, the rock core in quartz ampoule is taken out to execute one by one be listed as.
The method for removing hydrargyrum of mercurous rock core of the present invention has been realized the mercuryless processing of mercurous rock core, and the rock core after processing can be processed by normal rock core, and collecting the mercury obtained can recycle.
The accompanying drawing explanation.
Fig. 1 is mercurous rock core mercury removal device flow chart.
The specific embodiment
The method for removing hydrargyrum of mercurous rock core of the present invention device used is comprised of tube furnace 7, quartz ampoule 1, condenser 2, receiving flask 3 and vavuum pump 4; Quartz ampoule 1 one end openings, openend is connected with glass tube with the condenser air inlet; Condensed water water inlet 5 pipes of condenser are connected with rubber tube with running water pipe; Condenser outlet pipe 6 use rubber tubes pass to sewer; Receiving flask 5 joins with the collection mouth of condenser; The gas outlet of condenser is connected with rubber tube with vavuum pump 4 air inlets.
A plurality of cylindrical mercurous rock cores are put into to quartz ampoule 1 successively, then quartz ampoule is put into to tube furnace 7, the openend of quartz ampoule 1 extends to outside tube furnace, and the quartz ampoule part that extends to the tube furnace outer end does not comprise mercurous rock core.Then pressing Fig. 1 is connected with condenser 2 air inlets quartz ampoule 1 openend with rubber tube, the condensed water water inlet pipe 5 of condenser 2 and running water pipe with rubber tube be connected, condenser outlet pipe 6 use rubber tubes pass to sewer, condenser 2 is vertically placed, and gas outlet is upper, collect mouthful below.Receiving flask 3 joins with the collection mouth of condenser 2; The gas outlet of condenser and vavuum pump 4 air inlets are with rubber tube be connected (as Fig. 1).
Open the running water switch of the condensed water water inlet pipe of condenser after having connected, open vavuum pump, set the temperature spot (higher than the boiling point of mercury: 629.88K(356.73 ℃)) of tube furnace, the switch of opening tube furnace is heated.
Liquid mercury under the effect of heat energy and vacuum in rock core gasifies gradually, and then be evaporated from the rock core body, the mercury vapour constantly evaporated advances people's condenser under the effect of vacuum, because the fusing point of mercury is 234.32K(-38.83 ℃), so mercury is condensed into liquid mercury in condenser, under Action of Gravity Field, liquid mercury flows into a receiving flask along the condenser inwall through collecting mouth.
