Embodiment: as shown in Figure 1:
A kind of online solution concentration meter, this densimeter comprises liquid level gauge, inner sleeve 5, last outer tube 8, last pressure tube 9, shunting outer tube 20, following pressure tube 12, following outer tube 21 and mark fluid cylinder 14, described outer tube 8 upper ends of going up are communicated with recirculatory pipe 7, the lower end has opening and is inserted into described going up in the pressure tube 9, the upper end of described shunting outer tube 20 is communicated with described pressure tube 9 one that go up, the lower end has opening and is inserted in the described pressure tube 12 down, the upper end of described outer tube 21 down is communicated with described pressure tube 12 one down, the lower end is provided with variable valve 16, described inner sleeve 5 penetrates through last pressure tube 9 from described outer tube 8 upper ends of going up, shunting outer tube 20, following pressure tube 12 arrives the bottom of outer tube 21 down, vertically be communicated with the extension 10 of upper end closed on the described pressure tube 12 down, described mark fluid cylinder 14 is communicated with described inner sleeve 5 bottoms by piercing into described outer tube 21 down liquid phase communicating pipe 13, mark fluid cylinder 14 vertically is communicated with the gas-liquid communicating pipe 11 of upper end open, passes the top that described pressure tube 12 down extend into described extension 10 this gas-liquid communicating pipe 11; Described inner sleeve 5 is gone up between the pressure tube 9 by being communicated with described gas phase communicating pipe 17 with described, and liquid level gauge is equipped with in the upper end of inner sleeve 5, and this liquid level gauge comprises gauge outfit 3, sealing adaptor 4 and electrode 6, and described electrode 6 is inserted in the described inner sleeve 5; Connect technology at the middle part of described shunting outer tube 20 and be responsible for 1, be provided with drain valve 2 between this technology person in charge 1 and the described shunting outer tube 20.
The described link of going up pressure tube 9 and described shunting outer tube 20 is an infundibulate.
Described pressure tube 12 down is an infundibulate with the described link of outer tube 21 down.
Described mark fluid cylinder 14 is provided with mark liquid bleed valve 15.
Inner sleeve 5, go up outer tube 8, go up pressure tube 9, shunting outer tube 20, pressure tube 12, outer tube 21 and mark fluid cylinder 14 down down, last recirculatory pipe 7, variable valve 16, extension 10, gas-liquid communicating pipe 11, gas phase communicating pipe 17, gauge outfit 3, sealing adaptor 4 and electrode 6, technology is responsible for 1, drain valve 2.Liquid phase communicating pipe 13
Above-mentioned instrument adopts the principle of static balance to realize detecting by following steps:
1, liquid level gauge is demarcated, concrete steps are: open variable valve 16 earlier and open drain valve 2 again, test solution 19 is responsible for 1 from technology and is drawn, and after drain valve 2 enters shunting outer tube 20, passes through variable valve 16 respectively, goes up recirculatory pipe 7 retrieval systems.
When detected solution is rising in the pressure tube 12 down, gas in the following pressure tube 12 is by shunting outer tube 20, last outer tube 8 and upward recirculatory pipe 7 discharges, when rising to described shunting outer tube 20 lower ending opening places, continues in shunting outer tube 20 uphill process after with closure of openings detected solution, gas in the following pressure tube 12 will be extruded, air pressure increases by extension 10, the titer 18 that gas-liquid communicating pipes 11 compressing is marked in the fluid cylinder 14 also rises by entering inner sleeve 5 liquid phase communicating pipe 13, when detected solution rises in the pressure tube 9 and last outer tube 8 lower ending openings is sealed, gas also was closed through the path that last outer tube 8 reaches upward recirculatory pipe 7 discharges by gas phase communicating pipe 17 in the inner sleeve 5, though detected solution continue to rise, titer 18 in inner sleeve 5, stop to rise (this stage criterion liquid 18 begin to rise to the difference in height that test solution 19 rises when stopping to rise all be identical).Read correlation values by liquid level gauge this moment, when measuring first measurement of concetration is carried out in test solution 19 samplings of flowing out from last recirculatory pipe 7, when titer 18 stops to rise, continue to close variable valve 16 behind the of short duration feeding test solution 19 and drain valve 2 remains static test solution, adjust the sampling detected value of the reading of gauge outfit 3 to test solution, open variable valve 16 and drain valve 2 once more test solution continue to be flowed, make the reading of gauge outfit 3 get back to sampling detected value (promptly the reading when closing is consistent) by adjusting variable valve 16.
2, finish the online concentration inspection that promptly can be used for production line after the demarcation, after test solution 19 is drawn this detecting instrument by the technology person in charge, just can know instant concentration situation by the reading that reads gauge outfit 1, just reflect in this gauge outfit 1 so if the solution concentration of producing sometime is below or above standard value.
Aforesaid way be according to solution fluid column static pressure with density, density again with the characteristic of concentration change; According to what communicating pipe equate to design at each arm static pressure of stationary state.Because density will change with temperature; Communicating pipe, each arm static pressure also will reach pipe resistance with flowing to be changed in flow state.For eliminating temperature effect, present embodiment allows pressure tube 9, shunting outer tube 20, down pressure tube 12, titer 18 heat exchange each other in the test solution 19 in the outer tube 21 and the inner sleeve 5 down, temperature is consistent, allow titer 18 and the detected solution be approaching, make the rate of expanding with heat and contract with cold approaching with a kind of solution or concentration; Allow shunting outer tube 20 lower ending openings to last outer tube 8 lower ending opening constant height again, promptly titer 18 stops from beginning to rise to, and the detected solution lifting height is constant, and flow state flows and the pipe resistance influence in order to eliminate, and present embodiment is regulated by variable valve 16.
To sum up, the characteristics of this instrument are:
1, utilize shunting outer tube 20 lower ending openings to upper outer tube 8 lower ending opening constant height, the height that test solution 19 titer that promotes 18 of variable concentrations rises is different, judge thus or read the actual conditions of concentration, test solution 19 is in case outer tube 8 lower ending openings are sealed in arrival, and the rising of titer 18 will stop. Allow simultaneously the cross section of mark fluid cylinder 1 much larger than inner sleeve 5, so that can ignore because of the change in location of the caused titer 18 of variations in temperature in inner sleeve 5; Again because of above-mentioned shunting outer tube 20 lower ending openings to upper outer tube 8 lower ending opening constant height, like this so that the change in location of titer 18 in inner sleeve 5 only with change in concentration.
2, when titer 18 stops to rise, continue of short duration passing into and close control valve 16 behind the test solution 19 and drain valve 2 remains static test solution, adjust the reading of gauge outfit 3 to the sampling detected value of test solution, again open control valve 16 and drain valve 2 test solution continue to be flowed, make the reading of gauge outfit 3 get back to sampling detected value (namely the reading when closing is consistent) by adjusting control valve 16. This step is the error in reading of bringing because of liquid flow in order to eliminate.
Liquid level gauge is selected the Intelligent Capacitive liquid level gauge in this programme, has been matured product, has only converted the stoste position digital signal to the percent concentration data signal just. After this Intelligent Capacitive liquid level gauge passes through above-mentioned first measurement demarcation, the numerical value after will automatically reading in real time.
