Description of the embodiments
The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.
As shown in fig. 1 and 2, the portable multi-gas combination detecting device comprises a hollow box body 4, a replaceable built-in film bag 9 is arranged in the box body 4, and a ventilation hole 5 and a bacterial index sampling port 6 are arranged on the side wall of the box body 4. The air holes 5 facilitate the air in the box to be discharged outwards when the detection medium enters the box.
The top of the box 4 is provided with a sampling connecting pipe 1, a first detector inserting port 41 and a second detector inserting port 42, the first detector inserting port 41 is provided with a first separable detector 7, and the second detector inserting port 42 is internally provided with a second separable detector 8. The first detector 7 is a hydrogen sulfide detector and the second detector 8 is a carbon dioxide detector.
The case body 4 is further provided with a openable case cover, which will not be described here.
The built-in film bag 9 is made of plastic material and can be stacked and stored. The inner bag 9 is provided with a filter veil 10, the filter veil 10 divides the inner bag 9 into an upper space 91 and a lower space 92, and the volume of the upper space 91 is larger than that of the lower space 92.
Since the upper space 91 of the inner bag 9 has a larger volume than the lower space 92, the filtering veil 10 can be used to rapidly separate oil from water, and the separated water is used for sampling and detecting bacteria.
The bacterial index sampling port 6, the first detector insertion port 41 and the second detector insertion port 42 are each made of soft rubber. The first detector insertion port 41 and the second detector insertion port 42 have a certain ductility, and are suitable for different types of detectors.
In addition, a pair of quick scratching buckles 3 are arranged on the side wall of the box body 4, a detachable handle 2 is arranged between the quick scratching buckles 3, the portable lifting is convenient, and the portable lifting can also be hung on a sampling pipe line during detection.
In addition, the sampling connecting pipe 1 is made of soft rubber, can be simply closed up, and can prevent the overflow of gas, oil and water.
The method of using the portable multi-gas combination detection device will be described below.
First, the built-in film bag 9 is unfolded and placed in the case 4.
Next, the first detector 7 and the second detector 8 are inserted into the first detector insertion port 41 and the second detector insertion port 42, respectively, and both detectors are opened. After the two detectors are started, the sampling connecting pipe 1 is opened, and data is read after waiting for 3 minutes. If the data is stable within 1 minute, the data is read. If the data is not stable, wait for another 2 minutes and re-read.
