Abstract
The utility model relates to a ray dipolar smoke and dust sensor which belongs to a sensitive technique for solving the detection of dust concentration for boilers, industrial furnaces and dust blowing places and aspects. The utility model has the advantage of simplifying the complicated structure of an existing ray smoke and dust sensor, and the utility model is a ray dipolar smoke and dust sensor using a ray source as a base and another sampling pole. The utility model is a sensitive device used for rapidly detecting smoke and dust and detecting the dust concentration on the front end of a continuous flue monitor.
Description
This utility model relates to the detection technique of environmental protection and labour protection, particularly to the device of the monitoring or the detection of flue dust.
The dust in the flue dust of boiler and place, airborne dust source is one of environmental pollution and human body key factor of being injured.Common detection method is the heavy method of filter membrane meter both at home and abroad, the equipment heaviness, and test period is long, can not realize online continuous monitoring (seeing GB GB5468-91) again.Photoelectric method monitoring flue dust, gas turbidity are arranged, but that it is influenced by dust size and color is very big both at home and abroad, so must often demarcate correction according to working conditions change.In addition, the filter membrane that replaces balance irradiation sampling front and back with ray is arranged, calculate the dust concentration value, still there is the drawback of the heavy method of filter membrane meter in this method, and trueness error is big, is difficult to realize on-line monitoring.The β ray smoke gas sensor complex structure of patent of invention a few years ago, manufacture difficulty is big.
The purpose of this utility model is to be relative two utmost points of substrate and another sampling utmost point with the beta ray source, has changed the labyrinth of former ray smoke gas sensor, improves precision, is convenient to processing and use and cleaning again and pollutes.
The utility model is that the principle that ionization absorbs takes place when passing through flue dust according to radioactive isotope; make two relative pole plates; be contained in the shell through poly-tetrafluoro insulating material insulation; one power supply interpolar embedding, one radiographic source is substrate; another utmost point of very taking a sample; also establish a protection pole piece, form the smoke gas sensor main body.Also can be designed to cylinder type, radiographic source makes dust stream by sensor cavity at the side of two interpolars, measures dust concentration.Also available air pump is got the definite value flow in non-pipeline place test dust.
Owing to adopt the relative diarch structure of technique scheme, promptly simple in structure, improve not only precision but also processing and easy to clean pollute easily.
The concrete theory structure such as the accompanying drawing of utility model.
This utility model is a ray diarch smoke gas sensor, and it has shell (1) pole plate (2) (7), protection pole piece (3), insulation course (4) (5) and is embedded in the middle radiographic source (6) of pole plate (7) forms sensor body.
Cut open figure according to the ray diarch smoke gas sensor that the utility model proposes,
Its concrete working routine is as follows:
Flue dust enters cavity between two pole plates (2) (7) that are arranged on the insulation course (4) (5) with air-flow from shell (1) one end, discharge from the other end again, as the direction of figure one arrow indication, flue dust is carried out ionization absorb, the changing value of ray is measured the dust concentration value through secondary instrument.Protection pole piece (3) is to eliminate undesired signal, and when structure was made circle, radiographic source (6) is side aside, and dust enters the sensor inner chamber on every side from radiographic source (6), and the other end is discharged.Reach when needing cleaning in that two pole plates (2) (7) and radiographic source (6) are contaminated, blow to the other end with the wind of certain pressure from an end and clear up.
Claims (2)
1, a kind of ray diarch smoke gas sensor that flue dust is carried out on-line continuous monitoring or fast detecting; it is characterized in that: ray diarch smoke gas sensor; be provided with pole plate (2) and pole plate (7); be provided with protection pole piece (3) at pole plate (2) back side, middle embedding one radiographic source (6) of another pole plate (7).
2, ray diarch smoke gas sensor according to claim 1 is characterized in that the structure of diarch smoke gas sensor also can be made into the cylinder type sensor, and radiographic source (6) is at the side of two interpolars.
