Method and apparatus for measuring gas forming quantity of calcium carbide by using single calibrating weight method

The invention relates to a method and an apparatus for measuring the gas forming quantity of calcium carbide by using a single calibrating weight method, belonging to the technical field of chemical detection. The apparatus for measuring the gas forming quantity of calcium carbide by using a single calibrating weight method comprises a weight weighing machine, a reactor and a gas purifier, wherein a gas inlet of the gas purifier is connected with a gas outlet of the reactor; the reactor and the gas purifier are arranged on the upper part of the weight weighing machine; and the weight weighingmachine weighs the weight of the reactor and the gas purifier. In addition, the invention also provides a method for detecting the gas forming quantity of the calcium carbide by utilizing mass variation values before and after the weighed calcium carbide reacts with water. The invention has accurate measurement data, simple and convenient operation method, small volume of the measurement device, low price, convenient use
