Description

Continuous monitor for fluid

The utility model relates to a kind of analysis and detecting instrument that is applicable to fluid, especially a kind of fluid continuous monitor.

At present, monitoring stream volume property such as proportion, mostly devices such as soda acid are intermittent, the inconvenience of the following several respects of ubiquity: intermittently measuring is that a kind of hysteresis is measured, can not in time reflect the instantaneous variation of fluid in production system, not have the purpose of commander's production promptly and accurately; Intermittently mostly mensuration is not airtight, inaccurate to the bad mensuration of the fluid volatile, poisonous, that system temperature is high, and contaminated environment is unfavorable to operating personnel's health; Intermittently measure and is not connected with system, the sample of mensuration can't flow automatically in the reflux system, need add sample of preparation and accumulate container, and timing is with manually pouring in the system.

Have and adopt airtight method to measure, but need additional other device, as lever, ball float, vacuum etc., so it can not directly see reading, the accuracy that influence is measured from device.Also useful ultrasound wave, electromagnetism etc. add the device of the form METHOD FOR CONTINUOUS DETERMINATION of condition, but need add as power supply, pressurized air, electronic component etc., system complex, interference is many, poor accuracy, and monitoring function is single, cost height, maintenance difficult, particularly anticorrosion problem does not solve, so can't large-scale popularization use.

But the purpose of this utility model provide a kind of in same device the performances such as proportion, soda acid of intuitive and convenient ground continuous monitoring fluid in airtight production system, corrosion-resistant, volume is little, practical fluid continuous monitor.

The utility model is made up of transparent cylindrical shell, base, thermometer, picnometer, separating funnel, balance pipe, overflowing bent pipe etc.

Describe in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

This monitor is potential energy and the kinetic energy that utilizes fluid self, fluid is flow in the special monitoring device that picnometer and the automatic monitoring of soda acid are housed voluntarily, from monitor, can observe directly the instantaneous variation of the proportion and the Acidity of Aikalinity of fluid, from the proportion of fluid and temperature, concentration relationship table, at any time can find the moment concentration or content of fluid, can judge Acidity of Aikalinity, the neutrality of fluid from the change color of fluid, monitor is equipped with and the pressure balanced weighing apparatus pressure device of fluid system, flows back to fluid system through run-down pipe again so fluid can flow to monitor voluntarily.

This monitor is cylindrical, is made up of transparent cylindrical shell (7) and base (10) two joints, and middle card is respectively put a rubber cushion up and down with card (9) connection, is inserted in the blue screw hole of valve with screw then and fixes, and makes it not leak fluid.Picnometer (6), overflowing bent pipe (8) are housed in the cylindrical shell (7), and cylinder top seals with valve orchid, rubber cushion (5).Two separating funnels (2) are connected with two logical heads of threeway balance pipe (3) respectively, and pass through rubber cushion (5) simultaneously with its pipe core and insert in the cylindrical shell (7), thermometer (1) also inserts in the cylindrical shell (7) by top rubber cushion (5) respectively with a balance pipe (4).Base (10) both sides have hole a, the b for fluid inlet and outlet, and L type overflowing bent pipe (8) is perpendicular to base and be inserted in plug (11) and be fixed in outlet b.

The import a of this monitor is inserted the outlet front end of institute's fluid measured equipment or pipeline, balance pipe is connected on institute's fluid measured equipment, the outlet middle-end of pipeline, outlet b is connected on institute's fluid measured equipment, the rear end of pipeline, separating funnel balance pipe and monitor balance pipe are connected, after connecting, with acid, neutralization indicator injects separating funnel, the unlatching monitor is imported and exported, the balance pipe switch, detected fluid relies on potential energy of self and kinetic energy to prolong inflow monitor with prolonging, when fluid level arrives the overflow nozzle position, fluid is got back to institute's fluid measured equipment or the pipeline from the overflowing bent pipe overflow and is gone, picnometer floats on the fluid level, fluctuates along with the size of specific gravity, can know the scale of seeing picnometer from glass tube, proportion from fluid, the temperature relation table, can find the moment concentration or content of fluid, regulate the separating funnel switch, control the rate of addition of acid base indicator with this, when indicator is added drop-wise to fluid, can judge that the moment Acidity of Aikalinity of fluid changes from the change color of fluid.

The utility model will be monitored functions such as specific gravity, Acidity of Aikalinity and will be melted into a whole, and both can use simultaneously, also can use separately, and in same device, but performances such as the proportion of intuitive and convenient ground continuous monitoring fluid in airtight production system, soda acid.The utility model has solved the corrosion to monitor of fluid and environment, and the higher temperatures problem can have soda acid, fluid system temperature below 150 ℃, gauge pressure 1Kg/CM ²Use in the following production environment.This monitor is airtight, and is connected into an airtight system with production system, after installation regulates, need not manually-operated, and nonpollution environment can be drawn to the process(ing) cell and observe monitoring for operating personnel.Simultaneously do not need to add any condition, do not need to change the device of former fluid system, also do not need attachment devices such as fire prevention, explosion-proof, gas defence, volume is little, in light weight, take up an area of and lack, capital cost is extremely low, need not the special maintenance personal of electric instrument, maintenance expense is low, and wide adaptability is practical.
