Embodiment Construction
[0032] The detection method embodiment of combustible gas in this water comprises the following steps:
[0033] Ⅰ. Sampling tools
[0034] Such as figure 1 As shown, sampling bottle 1 is a clean 300 ml glass Erlenmeyer flask.
[0035] The mouth of the bottle is equipped with a sealing rubber plug 2, and the center hole of the rubber plug 2 is inserted with a glass tube 3 with a diameter of 10 mm and a length of 5 cm. , one end of the rubber tube 4 with a length of 8 cm is inserted into the upper end 3 cm of the glass tube 3, and the rubber tube 4 is sealed with the glass tube 3;
[0036] Ⅱ. Sampling
[0037] The measured circulating water temperature of the heat exchanger is lower than 80°C;
[0038] Remove the rubber plug 2, and rinse the sampling bottle 1, rubber plug 2, glass tube 3, and rubber tube 4 three times with the circulating water of the heat exchanger;
[0039] The sampling bottle 1 is filled with circulating water of the heat exchanger, covered with a rubber...

Abstract
The invention discloses a detection method for combustible gas in water.The method comprises the following steps that 1, a sampling tool sampling bottle is a clean container, a sealing rubber plug is matched with a bottle opening, a glass tube is inserted into a center hole of the rubber plug, the upper end of the glass tube stretches out of the rubber plug and is in sealed connection with the rubber tube; 2, during sampling, the sampling bottle is washed with circulating water and then filled with water, the sampling bottle is covered with the rubber plug, water stored in the rubber tube is extruded out with hand, and the outer end of the rubber tube is clamped at a rubber tube clamp; 3, the sampling bottle is shaken continuously for several minutes, gas in water is separated out, shaking is stopped, and detection is prepared after standing and defoaming; 4, a combustible gas alarm apparatus is started, and reading is returned to zero; the outer end of the rubber tube is pressed on a gas inlet of the alarm apparatus, the rubber tube clamp is opened, and a reading is obtained; the steps 2, 3 and 4 are executed repeatedly, and the average value of the readings is the result; 5, when the reading is smaller than 1, no combustible gas is leaked; when the reading is larger than 5.0%, more combustible gas is leaked.The combustible gas alarm apparatus can detect hydrogen gas, methane, ethane, propylene, propane and other refinery gases.The method is rapid, convenient and easy to implement.
Description
technical field [0001] The invention relates to the detection of combustible gas, in particular to a detection method of combustible gas in water. Background technique [0002] There are many heat exchangers in petroleum refining and chemical enterprises, and the heat exchangers mostly use circulating water, heat medium water, etc. as the medium for cooling or heating. During the operation of the heat exchanger, it is inevitable that combustible gas will leak into the circulating medium. As the operating cycle increases, the concentration of combustible gases in the water increases. When the combustible gases are enriched in circulating water plants or heat medium water stations, safety production accidents may occur. [0003] In order to prevent the risk caused by the leakage of combustible gas in the circulating water of the heat exchanger, the refining and chemical enterprises generally use methods such as analyzing the turbidity or conductivity of the circulating water ...
