Description
Technical field
The utility model belongs to liquid energy-storage field, is related to a kind of sampler of electrolyte in liquid energy-storage system.
Background technology
In liquid energy-storage running, analysis need to be sampled to the chemical property of electrolyte, the electrolysis in storage device
Liquid is for Main Analysis object, it is necessary to take liquid to electrolyte, and at present, sampling mode mainly includes several lower two kinds：
Mode one：Sample tap is reserved on energy-storage system operation pipeline, sample is accessed from sample tap；
This kind of sampling mode has the disadvantage that：
A. sample tap position determines when designing energy storage system pipeline, the later stage sample position be not easy to change.Due to electrolysis
Liquid when energy-storage system is run chemical property can real-time change, electrolyte and storing up electricity solution chemistry in storage device in pipeline
It is not consistent, thus the electrolye analysis result that such a sampling mode takes out has limitation.
B. because sampling analysis has real-time, therefore before every sub-sampling, the electrolysis of residual before need to discharging at sample tap
Liquid, to reduce entrained electrolyte error to caused by analysis result.Sample only needs 5-10ml capacity, but lifting rate exists every time
0.5-1L, it is 100-200 times of sample size, and the electrolyte discharged is respectively formed wastes, increase operating cost.
C. electrolyte easily crystallizes in static pipeline, so as to block sample tap：
When a) per sub-sampling, electrolyte is influenceed by the sample tap blocked, easily causes electrolyte splash, causes electrolyte unrestrained
Take, increase operating cost.
B) such as sample tap is cleared up before sampling, then additionally increases the job costs of sampling personnel；And Subsampling mouth
Stopping state is serious, need to change sample tap, increases maintenance cost.
When D. sampling, it is limited to sample tap and valve opening size, sampling amount is difficult to control, and the sample having more forms wave
Take, increase operating cost.
Mode two：The manhole of energy-accumulating medium storage device is opened, is directly contained from storage device and takes sample；
This kind of sampling mode has the disadvantage that：
A. such a mode can only use in small-sized storage device, as storage device highly be more than 1.2 meters, Ci Zhongfang
Formula will be no longer applicable.
B. sample number it is more when, frequently open the manhole of storage device, by the work of great increase sampling personnel into
This, reduces operating efficiency, while will also influence the sealing of storage device.
Except this, above two sampling mode also has the disadvantage that simultaneously：
When A. sampling, it can not accomplish that electrolyte liquid and air are completely isolated, easily cause electrolyte liquid by air oxygen
Change, cause its chemical property to change, impact analysis result accuracy.
B. it when energy-storage system is run, will make troubles to sampling work, thus generally enter under energy-storage system halted state
Row sampling work.
Utility model content
In order to solve due to operation pipeline on reserve sample tap, or storage device open manhole direct sample cause
Above-mentioned problems, the utility model uses following technical scheme：
The sampler of electrolyte in a kind of liquid energy-storage system, including electrolyte storage tank, peristaltic pump and sampling bottle, it is described
The surface of its body of electrolyte storage tank has preformed hole, and suction pipe is inserted inside electrolyte storage tank by preformed hole, the suction inlet position of suction pipe
Under electrolysis liquid surface, and suction pipe is communicated in peristaltic pump, and peristaltic pump connects with sampling bottle.
Further, hand-operated valve is installed on the suction pipe between described preformed hole and peristaltic pump.
Further, described electrolyte storage tank includes anolyte liquid storage tank and cathode electrolyte storage tank, peristaltic pump tool
There is a double pump head, the pump head all the way of the suction pipe connection in anolyte liquid storage tank, suction pipe connection in cathode electrolyte storage tank pump all the way
Head, each pump head connect a sampling bottle, and the inert gas for sealing is carried in sampling bottle.
Further, peristaltic pump has external communication interface, and the electric power system of peristaltic pump is connected to battery management system
(BMS)。
Further, the suction inlet of suction pipe is located at 1/3 or so under electrolysis liquid surface.
Further, the working flow of the peristaltic pump is 0.0016-500ml/ minutes, and suction pipe internal diameter is 0.8-7.9mm,
Tubing length is 0.1-2m.
Further, described peristaltic pump is between anolyte liquid storage tank and cathode electrolyte storage tank, and places high
Degree is substantially contour with electrolysis liquid surface, and preformed hole is located at the upper surface of electrolyte storage tank.
Beneficial effect：The utility model improves prior art, and thief hole is not reserved on operation pipeline, and selects storing
Device aperture, and the mode of this indirect manual sampling, storage device height is no longer limited by sample extraction by peristaltic pump
Degree, and sampling mode is by peristaltic pump pumps, manually participates in less, and sealing is preferable, and the analysis result of sample has reliability.Cause
The resorption function of peristaltic pump, the electrolyte remained after sampling can resorption need not carry out discharge opeing into storage device, during lower sub-sampling
Operation, thus not because discharge opeing and caused by electrolyte waste.In peristaltic pump suction pipe will not entrained electrolyte, therefore will not be because of electrolyte
Crystallization cause sampling line to block.The working flow of peristaltic pump can be set, therefore the sample size per sub-sampling can be controlled accurately, be subtracted
Electrolyte wastes caused by when sampling less.Inert gas shielding is carried in sampling bottle, can make electrolyte liquid and air completely every
From.Not by energy-storage system state limit during wriggling pump work, i.e., no matter whether energy-storage system stops, and sampling work can be carried out.
Peristaltic pump double pump head can be sampled work simultaneously, save both positive and negative polarity sample time, sampling equipment independently of energy-storage system, thus
Energy-storage system will not be had undesirable effect.
