Abstract
The utility model discloses an active carbon tube for catching mercury for measuring mercury in the gas in soil. A common glass tube (1) is provided with three concave rings (2, 4, 8), an inner layer glass tube (3) is arranged between the concave rings (2, 4), glass cotton (5, 7) is respectively arranged at the sites of the concave rings (4, 8), and active carbon (6) is arranged between the glass cotton (5, 7). As compared with golden wire tubes for catching mercury, the active carbon tube for catching mercury has lower production cost, better accuracy and primary mercury removal, and similar using method and quality.
Description
The utility model is that earth gas survey mercury looks for one in the technology of ore deposit to make a kind of sampling of mercury vapour enrichment and the device of analyzing.
Look at earth gas survey mercury at present and generally all use the spun gold mercury-traping tube in the technology of ore deposit, as the device of sampling and analysis.This pipe is owing to be to utilize spun gold to make adsorbent, and inner and outer pipes is made up of quartz glass, thus the processing technology complexity, spun gold Master Cost costliness, production cost is higher.Although each factory improves technical feature in order to fall the production cost of down payment silk mercury-traping tube, having designed various forms of spun gold mercury-traping tubes separately total is starting material because of not changing spun gold and quartz glass, and its cost price always can not be fallen.Again because survey in the mercury process at earth gas, every single beam mercury vapor analyzer is equipped with 200 spun gold mercury-traping tubes at least, could carry out productivity work, needed again in 3～5 years to upgrade once, owing to there is the selling at exorbitant prices of spun gold mercury-traping tube, be difficult to mostly be equipped with enough spun gold mercury-traping tubes, influence carrying out of productivity work.
Task of the present utility model is that a kind of mercury-traping tube with low cost of development replaces the spun gold mercury-traping tube.
Activated charcoal mercury-traping tube of the present utility model is by the glass tube (1) with three scrobicular rings (2,4,8), scrobicular ring is equipped with inner layer glass tube (3) between (2,4), glass wool (5,7) is equipped with at two places respectively at scrobicular ring (4,8), between glass wool (5,7) activated charcoal (6) is housed and constitutes.
The glass inner and outer pipes adopts 95 glass or GG-17 glass.The glass outer external diameter of pipe is less than 7 millimeters, internal diameter is advisable can hold inner layer glass tube, and 200～250 millimeters of pipe ranges, three scrobicular rings of outer layer glass tube are for fixing inner layer glass tube, the relative position of glass wool, activated charcoal and being provided with, glass tube two ends add that hotwork is slick and sly to be handled.The inside and outside footpath of inner layer glass tube, Wai layer Bo Li Guan And makes gas smoothly by being advisable packing into.Glass wool is an amount of, with fixing Huo Tan And gas is passed through smoothly.Activated charcoal is packed between the glass wool in the outer layer glass tube, and filling length is advisable with 25～40 millimeters, and activated charcoal is 20～40 order indefinite form particles.
Remarkable advantage of the present utility model is that the material of this mercury-traping tube is simple glass and activated charcoal, so material easily does, the cost of material also just falls at the end significantly, and processing technology is simple simultaneously, greatly reduces the cost of product.Also possess technical feature such as precision, first demercuration through this activated charcoal mercury-traping tube on probation, be better than the spun gold mercury-traping tube, using method is similar to the spun gold mercury-traping tube, and geological effect and the equal mutually characteristics of spun gold mercury-traping tube are good devices that a kind of earth gas is surveyed the mercury sampling and analyzed.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of activated charcoal mercury-traping tube.
Getting length is 230mm, and external diameter is 7mm, and internal diameter is one of 95 glass tube (1) of 4mm; Be heated to glass tube at the 90mm place of one end softening, is pressed into the dark scrobicular ring of about 1.5mm (2); Getting length then is 10mm, and external diameter is (3) scrobicular rings (2) of inserting glass tube (1) from the other end of 95 glass short tubes of 3.5mm; Be the position of fixing glass short tube (3), (1) Jia Re And is pressed into scrobicular ring (4) to the outer layer glass tube at the glass short tube other end of using the same method; Insert the end of an amount of glass wool (5) from the other end of glass tube (1) then to glass short tube (3); And then the activated charcoal of packing into (6) filling length is the 35mm of glass tube (1); Insert an amount of glass wool (7) again with fixing activated charcoal; At the glass tube (1) at this place, the heating that uses the same method is pressed into scrobicular ring (8) makes glass wool Yingization And be fixed on this place again; The slick and sly processing done at the two ends of last heating glass pipe (1).
Claims (4)
1, a kind of earth gas is surveyed the activated charcoal mercury-traping tube in the mercury technology, outer layer glass tube is arranged, it is characterized in that: by glass tube (1) with three scrobicular rings (2,4,8), scrobicular ring is equipped with inner layer glass tube (3) between (2,4), glass wool (5,7) is equipped with at scrobicular ring (4,8) two places respectively, between glass wool (5,7) activated charcoal (6) is housed and constitutes.
