Carefully be described as follows: along on direction straight up, the ratio of surface area and volume is gradually reduced steam evaporator 210, is made
Distilled water is very fast in the heating rate that is heated of steam evaporator 210, what distilled water moved upwards in steam evaporator 210
In the process, the heating surface area of unit volume distilled water is gradually reduced, and not only enables distilled water at the top of steam evaporator 210
Biggish disengagement area is kept, evaporation efficiency is improved；And the heating surface area of unit volume is relatively fewer, so that distilled water exists
The evaporated on top of steam evaporator 210 is relatively steady, and vapor is smoothly entered in quartz ampoule 310.
In addition, 210 lower end of steam evaporator is fixedly connected with vertical adapter tube 150, adapter tube 150 includes inner tube vertically for this
151 and outer tube 152,151 helical rotation of inner tube be connected in outer tube 152, the upper end of inner tube 151 and 210 bottom of steam evaporator
Portion is fixedly connected, and the lower end of inner tube 151 is connected to the liquid supply pipe 130 of transfusion unit 100, and outer tube 152 is fixed by sealing-plug 140
In the bottom end of quartz ampoule 310, when rotating inner tube 151, inner tube 151 can drive steam evaporator 210 in quartz ampoule 310
It moves up and down, and due in the quartz ampoule of heating furnace 300 310 in the vertical direction, there is different thermo parameters methods, pass through tune
Height and position of the water-saving steam generator 210 in quartz ampoule 310, convenient for adjusting steam evaporator 210 in different height
Heating temperature and the rate of heat addition, and then adjust the different proportion of different generation vapor and coke gasification reaction.
The upper end of steam evaporator 210 in the present embodiment is fixedly connected with current stabilization piece 220 and lower current stabilization piece 230,
It is evenly distributed with circular hole 221 on the upper current stabilization piece 220 and lower current stabilization piece 230, is equipped with bur 222 on the inside of the circular hole 221, it should
Bur 222 by circular hole 221 inner wall thereto the heart extend so that splash drop pass through circular hole 221 when, still can be with circular hole
The bur 222 of 221 insides collides, and avoids splash drop and smoothly passes through circular hole 221.The upper current stabilization piece 220 is under
Spacing on the vertical direction of current stabilization piece 230 is less than the diameter of lower 230 circular hole 221 of current stabilization piece, so that splash drop is in the case where passing through
After 230 circular hole of current stabilization piece, the position of current stabilization piece 220 is reached soon, and is easier to be stopped by upper current stabilization piece 220, into
And prevent water from causing damages because of splash；Upper current stabilization piece 220 is interspersed with the circular hole 221 on lower current stabilization piece 230, i.e., upper current stabilization
The geometric center of the circular hole 221 of the circular hole 221 of piece 220 and lower current stabilization piece 230 is not in same vertical straight line.When liquid sprays
When splashing, drop can move under the action of splash active force towards the opening direction of steam evaporator 210, and drop is being transported upwards
In dynamic process, partial drop can be stopped by the lower current stabilization piece 230 of high temperature, rest on lower current stabilization piece 230, and by under high temperature
Gasification produces vapor to current stabilization piece 230 rapidly；In addition, the drop of another part can fly from the circular hole 221 of lower current stabilization piece 230
Out, since upper current stabilization piece 220 and the circular hole 221 on lower current stabilization piece 230 are interspersed, even if so that drop passes through lower current stabilization piece
230 circular hole 221 can also be stopped by upper current stabilization piece 220, and gasification produces vapor rapidly by the upper current stabilization piece 220 of high temperature,
Prevent droplets and caused by water loss, and then ensure that the accuracy that coke is reacted with vapor in experimentation.

Platinum-rhodium alloy；Electrical signal detection device is used to detect the change in electric between first electrode and second electrode.When liquid level reaches liquid
When the height that position detecting mechanism 240 is arranged, the potential between level detection mechanism 240 can change, first electrode and second
Electric signal is generated between electrode, has solution to be connected between first electrode and second electrode, so that electrical signal detection device detects
Obtained electric signal, which will be sent, to be changed, and the jump signal that electrical signal detection device detects is transferred to speed-regulating type peristaltic pump 120, subtracts
The flow of small speed-regulating type peristaltic pump 120, prevents the liquid level in steam evaporator 210 excessively high, so that in steam evaporator 210
Highest liquid level still be below the lower surface of lower current stabilization piece 230；On the one hand, water is avoided to overflow evaporation element 200；On the other hand,
So that liquid is in the circular hole 221 for occurring to be necessarily required to continue to pass through lower current stabilization piece 230 and upper current stabilization piece 220 during splash,
The drop of splash is possible to splash to the outside of evaporation element 200, thus efficiently avoid droplets and caused by water
Amount loss.
