Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a water collector for a hydrogen sulfide gas detector. Background Art

[0002] Hydrogen sulfide (H2S) is flammable and can easily form explosive mixtures when mixed with air. It can cause combustion and explosion when exposed to open flames and high heat. It can react violently with concentrated nitric acid, fuming sulfuric acid or other strong oxidants and explode. H2S gas is heavier than air and can diffuse to a considerable distance at a lower level. It will burn when exposed to open flames. In production sites in various chemical fields, such as reactors, reaction tanks, reaction pools and other areas, portable detection is required to strictly control the leakage of hydrogen sulfide gas.

[0003] The working mode of the portable pump-suction hydrogen sulfide gas detector is that the air pump continuously extracts and samples the hydrogen sulfide gas in the sewage pool or sewer area through the air pipe, and then sends the hydrogen sulfide gas to the instrument for detection. However, in the process of gas extraction and detection, it is inevitable that the gas contains water vapor, which enters the portable pump-suction hydrogen sulfide gas detector or its air pump, causing corrosion and damage to the instrument, reducing the service life of the equipment and increasing maintenance costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above-mentioned defects in the prior art and provide a water collector for a hydrogen sulfide gas detector, which is easy to install, prolongs the service life of the equipment, reduces maintenance work and improves work efficiency.

[0005] The water collector of the hydrogen sulfide gas detector described in the utility model comprises a water collecting bottle, a recessed ring is arranged on the water collecting bottle, a filter is arranged inside the water collecting bottle, a desiccant is arranged on the filter, a bottle plug is arranged at the mouth of the water collecting bottle, an air inlet pneumatic hose and an air outlet pneumatic hose are arranged on the bottle plug, the air inlet pneumatic hose penetrates between the bottom of the water collecting bottle and the filter, the air inlet pneumatic hose is connected to the filter a, and the air outlet pneumatic hose is connected to the H2S gas detector.

[0006] The filter is placed on the protruding concave circle inside the water collection bottle. The desiccant is color-changing silica gel and can be recycled. The filter is made of polytetrafluoroethylene.

[0007] Preferably, the bottle stopper is provided with a hose outlet and a hose inlet, and the diameter of the hose outlet and the hose inlet is 6 mm.

[0008] Preferably, the bottom of the water collecting bottle is provided with a drain port, which is a waste liquid drain port with a diameter of 8 mm, connected with a rubber tube, and controlled by a metal spring water stop clip.

[0009] Preferably, the air inlet pneumatic hose is provided with an air inlet pneumatic hose connector, and the air outlet pneumatic hose is provided with an air outlet pneumatic hose connector. The air inlet pneumatic hose connector and the air outlet pneumatic hose connector are PU-6.

[0012] Preferably, an air suction pump is provided on the air inlet pipe of the H2S gas detector.

[0013] The mesh diameter of the filter is 6 mm, and the length is determined according to the length of the detection space.

[0014] The volume of the water collection bottle is 500mL, and it is made of transparent glass. When liquid water enters, it means that the filter head at the end of the pneumatic hose has penetrated into the liquid and is not in an effective detection environment or the current detection environment has high humidity. The bottle stopper is a rubber stopper, model 10#.

[0015] The water collector of the hydrogen sulfide gas detector described in the utility model, when working, the hydrogen sulfide gas in the space to be tested enters the bottom of the water collecting bottle through the filter a and the air inlet pneumatic hose, and the hydrogen sulfide gas passes through the desiccant and is connected to the H2S gas detector through the air outlet pneumatic hose on the upper part of the water collecting bottle for detection. When there is sewage or high humidity in the environment to be tested, the sewage or moisture in the environment to be tested is sucked into the H2S gas detector through the filter a and the air inlet pneumatic hose, causing corrosion and damage to the instrument.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] (1) In the water collector of the hydrogen sulfide gas detector of the utility model, the filtered gas at the end of the pneumatic hose intrudes into the sewage without being in an effective hydrogen sulfide gas environment or the current detection environment has high humidity, which will not cause corrosion damage to the detector host.
