Abstract
A kind of high temperature reference electrode system, the system are made of circulating water device, cooling salt Biodge device and reference electrode three parts；The reference electrode is installed on the top of cooling salt Biodge device, which is connected to by inlet and outlet pipes with circulating water device.The cooling salt Biodge device includes capillary, it is placed in cooling salt bridge housing center position, cavity between the capillary and cooling salt bridge shell is cooling chamber, salt bridge water inlet pipe is provided in the cooling chamber, the salt bridge water inlet pipe extends to cooling chamber bottom, salt bridge outlet pipe is located at cooling salt Biodge device top, and the salt bridge water inlet pipe and salt bridge outlet pipe are connected to the cycle for completing cooling water with circulating water device.The utility model can use under the hot environment of room temperature ~ 200 DEG C, and no matter the outer experimental solutions temperature of salt bridge is raised and lowered, and the temperature total energy of salt bridge and reference electrode is constant in room temperature.And it is easy to operate, of low cost, and can reuse.
Description
Technical field
The utility model is related to high-temperature electrochemistry experimental assembly technical field, more particularly to used under a kind of hot environment
Reference electrode system.
Background technology
Reference electrode, which is electrochemistry experiment, must use one of spare part.Reference electrode require current potential is stable, do not polarize or difficult polarization,
Media-resistant burn into not pollution medium, firm in structure, manufacture maintenance and the characteristics such as easy to use.Currently used reference electrode has
Hydrogen electrode, calomel electrode, Mercurous sulfate electrode, silver chloride electrode etc..Salt bridge is used between reference electrode and electrolyte experimental solutions
Excessively, salt bridge selects agar and potassium chloride, ammonium nitrate or potassium nitrate solution to make.However, these reference electrodes and salt bridge use
Temperature is limited, is generally not more than 60 DEG C, if temperature is higher, reference electrode internal electrolyte solution can be made to boil, salt bridge blistering
Or melt, lead to the failure of an experiment.
Utility model content
The utility model proposes a kind of high temperature reference electrode systems, can be used under the hot environment of room temperature ~ 200 DEG C, and grasp
Make simple, of low cost, and can reuse.
For this purpose, technical solution used by the utility model is：
A kind of high temperature reference electrode system, the system is by circulating water device, cooling salt Biodge device and reference electrode three parts
Composition；The reference electrode is installed on the top of cooling salt Biodge device, which passes through inlet and outlet pipes and recirculated water
Device is connected to.
The cooling salt Biodge device includes capillary, is placed in cooling salt bridge housing center position, the capillary and cooling
Cavity between salt bridge shell is cooling chamber, is provided with salt bridge water inlet pipe in the cooling chamber, which extends to cooling
Bottom of chamber portion, salt bridge outlet pipe are located at cooling salt Biodge device top, the salt bridge water inlet pipe and salt bridge outlet pipe and circulating water device
The cycle of cooling water is completed in connection.
The utility model can use under the hot environment of room temperature ~ 200 DEG C, and no matter the outer experimental solutions temperature of salt bridge is increased or dropped
Low, the temperature total energy of salt bridge and reference electrode is constant in room temperature.And it is easy to operate, of low cost, and can reuse.
Description of the drawings
Fig. 1 is the structural schematic diagram of the use of the new type.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of high temperature reference electrode system, the system is by circulating water device, cooling salt Biodge device and reference
Electrode three parts form.Pond 1, tap 3 and emulsion tube 3 form circulating water device；Salt bridge water inlet pipe 4, capillary 5, salt bridge
Outlet pipe 7 and cooling salt bridge shell 8 form cooling salt Biodge device；The reference electrode 6 is installed on the top of cooling salt Biodge device,
The cooling salt Biodge device is connected to by inlet and outlet pipes with circulating water device.
Capillary 5 in the cooling salt Biodge device is located at the center of cooling salt bridge, and stretches out 1~2mm of shell, the capillary
Cavity between pipe 5 and cooling salt bridge shell 8 is cooling chamber, is provided with salt bridge water inlet pipe 4 in the cooling chamber, the salt bridge water inlet pipe
4 one end extend to outer casing bottom, and the other end is connected to circulating water device；It is provided with salt bridge on the shell of 4 opposite side of salt bridge water inlet pipe
Outlet pipe 7, the salt bridge outlet pipe 7 are connected to circulating water device, to complete the cycle of cooling water.
Calomel electrode, Mercurous sulfate electrode or silver chloride electrode can be selected in reference electrode.
The cooling salt bridge package unit, such as salt bridge water inlet pipe 4, capillary 5, salt bridge outlet pipe 7 and cooling salt bridge shell 8
It is made of glass or stainless steel.With easy to manufacture and etch-proof performance.
Operating procedure is as follows when this system uses：
（1）Agar-electrolyte solution is poured into cooling salt bridge, installs reference electrode, is then installed to cooling salt bridge often
In warm electrolytic cell.
（2）Salt bridge water inlet pipe 4 is connect with tap 2 with emulsion tube 3, salt bridge outlet pipe 7 is connect with pond 1.
（3）Tap, electrolytic cell heating are opened, temperature can carry out experimental implementation after reaching required temperature.
After experiment, waits for that experimental solutions temperature is cooled to room temperature closing tap, take out salt bridge.
