Detailed description of the invention
This utility model is further described by the embodiment shown in below in conjunction with the accompanying drawings.
Chemical cleaning evaluation gas collection measurement apparatus as shown in Figure 1, mainly includes bottle 2, inner bag 3, bottle cap 4, valve 5
With graded tube 7 etc..
Wherein, in bottle 2 is generally positioned at water-bath 1.Inner bag 3(can be glass material) it is arranged on the top of bottle 2
Portion, and extend to the inside of bottle 2, for holding the incrustation scale scraped off or other question response solid matter；The bottom of inner bag 3
Without perforate, the uniformly perforate of the surrounding at the certain altitude of bottom of its sidewall (perforate height can select as required, preferably 5 ~
20 mm), aperture is Ф 2 ~ 5 mm.In the present embodiment, the bottleneck of bottle 2 is trapezoidal and band external screw thread, interior frosted, it is simple to interior
The installation of gallbladder 3, take out and seal, prevent gas leakage；Bottle 2 inwall is round and smooth, and surrounding rounded corners processes, it is to avoid bubble adsorbs and molten
Liquid is detained.Graded tube 7 is connected with the bottom of bottle 3, and (in the present embodiment, graded tube 7 is connected with the bottom of bottle 3 side
Logical), in bottle 3, add reactant liquor by graded tube 7；Their the built-in sand core filter of connectivity part (aperture Ф 10 ~ 15 μ
M), this sand core filter acid-alkali-corrosive-resisting and redox reaction, there is the effect filtering precipitate and washing gas, prevent anti-
Gas and byproduct of reaction should be produced because of in the violent diffusion mobility of stirring to graded tube 7；Graded tube 7 is with scale, as required
Select measurement scope and precision size (typically regulate different cross section size and regulate certainty of measurement).The corresponding closing lid of bottle cap 4 exists
On inner bag 3, in order to ensure to seal, gasket seal can be installed in bottle cap 4；Bottle cap 4 is provided with the flexible pipe being connected with inner bag 3
6, and the valve 5 controlling its break-make is set on flexible pipe 6；Bottle cap 4 is made up of Kynoar (PVDF) material, built-in fluorubber
Sealing gasket, flexible pipe 6 and valve 5 are PTFE material, have pressure, high temperature resistant, the property of acid-alkali-corrosive-resisting, resistance to oxidation reduction reaction
Matter, should be noted that cleanout fluid accident overflow when preventing valve 5 fault in use.Such gas collection measurement apparatus does not has attached joining
Part, efficiently solves the difficulty that in conventional apparatus, in solid-liquid reaction pipe and inducing QI sebific duct, residual gas cannot accurately measure, and improves
The accuracy measured；Reaction can be accurately conversed by the liquid level difference association reaction temperature before and after reaction in record graded tube 7
The gas flow produced.
Need first to check the air-tightness of whole gas collection measurement apparatus before the use, prevent it from leaking gas, particularly as follows: by water-bath
Pot 1 adds water to certain altitude so that water surface elevation exceeds the valve 5(of this gas collection measurement apparatus and i.e. adds water so that bottle 2 immerses water
Below body lotion face), it is ensured that not effervescent；If effervescent, the sealing gasket in bottle cap 4 need to be changed.In use, can be in water-bath
Add water to certain altitude in pot 1, controlled the temperature of chemical reaction process by the temperature of regulation water.In the present embodiment, carve
The height of degree pipe 7 is higher than the height of valve 5, to prevent reactant liquor from overflowing；The sectional area of graded tube 7 is less than the cross section of bottle 2
Long-pending, such graded tube 7 is the thinnest and precision of gas collection measurement apparatus is the highest；Reference zero graduation correspondence bottle cap 4 crown valve of graded tube 7
The position of door 5, its range correspondence bottle 2 sectional area and inner bag 3 product highly.In the present embodiment, it is placed with magnetic in bottle 2
Power stirrer 9, olive shape magnetic stir bar (length 35mm, the diameter that magnetic stir bar 9 is wrapped up for polytetrafluoroethylene (PTFE)
13mm), the mixing speed of chemical reaction is controlled by bottom magnetic force agitating heating device rotational speed regulation.
This gas collection measurement apparatus has self termination defencive function, when reaction is excessively strong, produces gas flow beyond measuring pipe
During range, corresponding bottle cohesion collection gas is also by the bottom of cleaning solution liquid level extruding to glass inner bag, and solution departs from solid
Contact, sluggish terminates.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with technique
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All according to this utility model spirit made equivalence change or modify, all should contain protection domain of the present utility model it
In.
