Embodiment 1

[0012] see figure 1 , The structure of the transmission type smoke meter includes a detection channel 1 for the gas to be tested to pass through, and fans 4 and 5 for forming air curtains 2 and 3 at the outlet of the detection channel. A light source 6 and a light receiver 7 are respectively provided at both ends of the detection channel to form a photometric system. Also see figure 1 , figure 2 , at the exit of one end of the detection channel 1, there is a light-transmitting sheet 8 that can be observed to form a curved flow beam under the blowing of the air curtain 2, and a straight line 9 is marked on the light-transmitting sheet. Viewed from the direction perpendicular to the light-transmitting sheet, the straight line 9 overlaps with the optical axis of the photometric system, so that the straight line 9 can represent the optical axis of the photometric system (the optical axis is represented by a dotted line in the figure). The light-transmitting sheet 8 can be made...

Embodiment 2

[0016] see image 3 , the main difference between this embodiment and Embodiment 1 is that the detection channel 1 is not a simple straight cylinder. For a detection channel of this type, the optical path of the light beam of the photometric system in the detection channel should be equal to the linear distance L3 between the exits at both ends of the detection channel. The straight-line distance L3 is also determined after the smoke meter is manufactured. Other structural features of this embodiment and the method for measuring the effective smoke column length of the smoke meter are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a transmission-type smoke meter capable of measuring valid smoke column length and a method for measuring valid smoke column length with the transmission-type smoke meter. The smoke meter is mainly characterized in that the outlet of the detecting path of the smoke meter is provided with a transparent sheet capable of observing the bending flow of detected gas, and a straight line representing the optical axis of the photometric system of the smoke meter is marked on the transparent sheet. The measuring method is mainly characterized in that coloured gas passes throughthe detecting path and an air curtain of the smoke meter; the optical distance of a light beam of the photometric system of the smoke meter in the bending flow of the coloured gas can be obtained by observing the straight line on the transparent sheet, and the obtained optical distance and the optical distance of the coloured gas in the detecting path are added to obtain the valid smoke column length of the smoke meter. The invention has the advantages that the transmission-type smoke meter has more scientificity, seriousness, objectivity and impartiality.

Description

technical field [0001] The present invention relates to the structure of a transmission type smoke meter and a method for measuring the effective smoke column length of such a smoke meter. Background technique [0002] In the national standard about the transmission smoke meter, the effective smoke column length of the smoke meter is required to be marked on the transmission smoke meter. However, there is no method for measuring the effective smoke column length of the transmission type smoke meter in the prior art, and no structure for measuring the effective smoke column length is provided for the transmission type smoke meter. Sexuality, seriousness, objectivity, doubts about impartiality. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a transmission type smoke meter capable of measuring the effective smoke column length, and a method for measuring the effective smoke column length of the transmission type smoke meter. [0004] To...
