Description

[Detailed description of the invention] This invention relates to a detection tube used to detect deterioration of kerosene, foreign components, etc., and detects combustion defects in kerosene-burning appliances that occur due to the use of such abnormal kerosene. The purpose is to prevent this from happening.

Even when kerosene is stored, it is susceptible to oxidation and deterioration due to atmospheric oxygen, environmental temperature, ultraviolet rays, etc., causing tarry components, which can have a negative effect on combustion, especially in kerosene stoves with wick-type burners. It was hot.

Additionally, water may be mixed into kerosene as a foreign component during refueling or as a result of dew condensation, causing poor combustion.

In order to be able to identify this change or dissimilar components in advance and prohibit their use, for example, α-naphtholbenzene with adjusted pH may be used as an indicator.
In the case of degraded kerosene, an altered kerosene detector has been proposed that identifies the degree of alteration based on a change in color tone.

However, in this case, it is difficult to recognize changes in color tone when the degree of alteration is small, and there is also the drawback that different components such as moisture cannot be detected simultaneously with a single detection tube.

The present invention eliminates the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to the drawings.

In the drawing, 1 is a pipe made of glass or plastic and open at both ends, and 2 is a partition wall located in the center of the pipe 1, dividing the pipe into two chambers, A chamber and B chamber. 3 is a slit formed near the partition wall 2 in the A room and the B room.

Reference numeral 4 seals both open ends of the pipe 1 with cotton filled at both ends of the pipe 1 and increases the kerosene wicking effect. 5 is a filler filled in the ends of chambers A and B on the partition wall 2 side, and the detection agent 6 filled in chambers A and B between the cotton 4 and the filler 5 flows out from the slit 3. It prevents you from doing so.

The detection agent 6 has the function of identifying kerosene deterioration components or foreign components. For example, activated alumina is impregnated with iodopotassium at a certain ratio to adjust the sensitivity to the deterioration components, or it is used as a detector for foreign components in water. Therefore, pararosaniline acetate, which emits a red color, is used.

When using such a detection tube, one end of the detection body is immersed in the kerosene to be identified and held upright.The kerosene is sucked up by surface tension through the cotton 4 and comes into contact with the detection agent 6. .

When the detection agent 6 is alumina iodopotassium, it reacts with the deterioration components to form a clear brown ring-shaped colored layer 7, and the degree of deterioration can be quantitatively identified by the length and color density of this coloring layer 7. can.

In this case, even though the pipe 1 is blocked by the partition wall 2, it is communicated with the atmosphere through the packed bed 5 and the slit 3, so there is no possibility that the kerosene suction power will be insufficient and this will interfere with detection. There isn't.

Furthermore, when the A room side is used, the partition wall 2 prevents kerosene from entering the B room side, so the B room side can be used as a completely separate and unused detector.

Furthermore, by using an alumina potassium iodide detector 6 having different detection sensitivities for deteriorated kerosene in chambers A and B, the detector can be used to confirm the limit of the degree of deterioration, or to detect both water and the degree of deterioration.

If it is difficult to form the partition wall 2, the central part of the pipe 1 itself may be thermocompressed to form A.
It may be divided into a room and a room B.

As described above, the present invention has great practical value as it allows easy and accurate detection of deterioration and foreign components in kerosene oil.
