Abstract

The invention discloses a constant-voltage closed-loop-controlled automatic tail gas collecting method and a constant-voltage closed-loop-controlled automatictail gas collecting device. A temperature sensor and a pressure sensor are respectively installed on two sides of the bottom of a cylinder cover, the center of the bottom of the cylinder cover is connected with one end of a capillary steel tube while the other end of the capillary steel tube is connected with the first end of a three-way valve, and the other two ends of the three-way valve arerespectively connected with an electromagnetic valve; the second end of the three-way valve is connected with a smoke analytic sampling container by virtue of the capillary steel tube; the gas inlet end of the capillary steel tube which is connected with the third end of the three-way valve, and a pressure sensor is installed at the upper end of a buffer box which is connected with the capillary steel tube; the output end of a drying device is connected with one side of the buffer box by virtue of the capillary steel tube; and the capillary steel tube at the output end of a combustion pond is connected with the capillary steel tube at the input end of the drying device by virtue of a quick connector. According to the method and the device disclosed by the invention, tail gas is automatically controlled and gathered. The pressure of a pipeline is automatically detected by virtue of the pressure sensor of the buffer box to control the rotating amount of the motor, so that the effect of collecting the tail gas is achieved.

Description

technical field [0001] The invention relates to a tail gas collection device and a corresponding collection method thereof, in particular to a constant pressure closed-loop control tail gas automatic collection method and device. Background technique [0002] In recent years, the research work on natural gas calorific value measurement has been carried out in many scientific research institutes. Energy measurement reflects the thermal energy of natural gas. As a reasonable and scientific measurement method that can best reflect the characteristics of its fuel, it is used in natural gas trade broadly used. [0003] However, volume measurement is still widely used as the basis for natural gas trade settlement in China. my country is still relatively backward in terms of gas calorific value measurement base standards including natural gas, and the existing gas calorific value measurement system cannot meet the rapid development of gas energy. Contents of the invention [00...
