Abstract
Provided is a device for continuously detecting the particle size of flocculating constituent in a coagulation beaker testing process. The device comprises a standard coagulation beaker, a laser particle size analyzer, a stirring motor, a peristaltic pump and a computer connected with the laser particle size analyzer. The flocculating constituent formed in the standard coagulation beaker is pumped into the laser particle size analyzer by using inlet power of the peristaltic pump, and real-time monitoring of flocculating constituent particle changing conditions in the coagulation beaker testing process is achieved. Compared with a conventional coagulation beaker test, the device enables users to observe forming, growth and breaking conditions of the flocculating constituent visually so as to provide precise guide for selection of coagulation process parameters.
Description
Technical field
But the utility model is the device that forms the particle diameter of floc unit in a kind of Continuous Observation coagulation beaker process of the test.
Background technology
Through to the steady process of taking off of hydrophobic colloid, particle, and the whole process that makes it to form flco is called coagulation.The coagulation phenomenon is one of ubiquitous phenomenon in nature and the artificial-strengthening water treatment system.Coagulation in the water treatment mainly passes through dosing coagulant, and imposes certain hydraulics promotion flco formation.The importance of coagulation is, if can correctly adopt then not only can remove coarse dispersion system and colloid pollution thing in the water body effectively, can also remove some dissolved matter effectively.
The purpose of coagulation is that the pollutant in the water body is removed with the form of solid particulate matter in feedwater and the sewage, and all solid particulate matters of these shape shapes may be generically referred to as floc unit.The characteristic of floc unit comprises particle diameter and distribution, Structure & Intensity etc., is one of most important operating parameter in industrial process and the water technology.And the test of coagulation beaker is the standard method when carrying out the selection of coagulation process parameter.General in the coagulation beaker process of the test of routine, only measure the macro-indicators such as turbidity, SS, COD of post precipitation supernatant, can't understand the actual particle size size of actual floc unit.Particle diameter how to measure floc unit is to have determined the key point of solid-liquid separation efficiency in the water treatment.
Summary of the invention
The purpose of the utility model has been to make up the monitoring device of a high precision, simple and easy suitable floc unit size, so that accurately judge the size of floc unit particle diameter in the coagulation beaker process of the test efficiently.
The device of floc unit particle diameter in a kind of METHOD FOR CONTINUOUS DETERMINATION coagulation beaker process of the test, it is characterized in that: (1) this device comprises standard coagulation beaker, laser particle analyzer, stirring motor, peristaltic pump and the computing machine that connects with laser particle analyzer; (2) through peristaltic pump the floc unit that forms in the standard coagulation beaker is continuously pumped into to laser particle analyzer, and through the continuous monitoring to the floc unit particle diameter of the computer realization that connects with this laser particle analyzer.
The utility model device; Through the standard coagulation beaker test unit of transforming; Utilize peristaltic pump that the floc unit that forms in the coagulation beaker is pumped into the Ma Erwen laser particle analyzer; Be connected to form the closed cycle of flco through flexible pipe after, but the granularity of formation floc unit in the continuous monitoring coagulation beaker process of the test.The use of this new device, comparable traditional conventional coagulation beaker test more can be observed the formation situation of floc unit intuitively, thereby instructs for the selection of coagulation process parameter provides more accurately.
Description of drawings:
In conjunction with explanation accompanying drawing 1, this device is elaborated.Among Fig. 1: 1. the standard coagulation test is with beaker (1 liter); 2. circulation peristaltic pump; 3. Ma Erwen laser particle analyzer; 4. computer; 5. be with the stirring motor of paddle; 6, the backwater flexible pipe; 7, delivery hose.
Embodiment:
1. will place standard coagulation beaker top with the stirring motor of paddle, through the rotating speed and the mixing time of certain procedure control stirring motor, to satisfy the purpose of coagulation beaker test.
2. be that 5 millimeters plastic flexible pipe (delivery hose and backwater flexible pipe) places beaker liquid level below 10 centimeters with two internal diameters respectively, and place by the diametric(al) symmetry.The other end of delivery hose is directly connected to the sample inlet end of Ma Erwen (Mastersizer 2000) laser particle size analyzer; And with the sample export that is connected to the Ma Erwen laser particle analyzer behind the return pipe elder generation process peristaltic pump.
3. after equipment installs, open the Ma Erwen laser particle analyzer earlier, next opens coagulation beaker test stirring motor, and dosing coagulant forms floc unit, opens peristaltic pump again.Broken in order to prevent the flco generation, the speed of control peristaltic pump is per minute 20-30 milliliter, and the pump housing of flowing through again behind the process delivery hose entering Ma Erwen of the flco elder generation laser particle analyzer, and gets back in the beaker through the backwater flexible pipe.Along with different coagulation time courses, but the floc unit change of size under the situation such as the formation of Continuous Observation floc unit, growth and fragmentation.
Claims (2)
1. the device of floc unit particle diameter in the METHOD FOR CONTINUOUS DETERMINATION coagulation beaker process of the test, it is characterized in that: this device comprises standard coagulation beaker, laser particle analyzer, stirring motor, peristaltic pump and the computing machine that connects with laser particle analyzer.
2. device according to claim 1 is characterized in that: through peristaltic pump the floc unit that forms in the standard coagulation beaker is continuously pumped into to laser particle analyzer, and through the continuous monitoring to the floc unit particle diameter of the computer realization that connects with this laser particle analyzer.
