Problems solved by technology

[0002] As the current mainstream gas collection and measurement method, the drainage method has the characteristics of low cost, intuitive effect, and easy learning. Parts, the required parts are more complicated
At the same time, the collection of gas is carried out underwater, which requires repeated manual operations, and the labor is highly repetitive.
There are many disadvantages in the measurement of drainage and gas collection using conventional equipment, for example: (1) the residual air in the conduit will pollute the collected gas, which will affect the determination of gas components in the later stage; (2) when the collected gas is mixed with When there is water vapor, the water vapor enters the gas collecting cylinder and causes gas volume measurement error; (3) When the collected gas is mixed with water vapor, part of the water vapor will condense and block the pipe due to the temperature drop, resulting in interruption of operation; (4) When there is a difference between the collected gas and the ambient temperature, it will cause the air pressure in the pipeline to be unstable and suck back, which will affect the experiment. 6) It is impossible to control the gas collection rate; (7) The sealing effect is poor, the sealing parts are easy to age, and the sealing problem occurs after use; (8) It needs to be operated with equipment such as a water tank, and the portability is poor, and it is inconvenient to use in the field; (9) Manual A lot of repetitive work, waste of manpower

Abstract

The invention discloses a gas-liquid pressure balance regulator and a water draining and gas collecting device with the same, and belongs to the field of gas measurement equipment based on a drainage method. The regulator includes a pressure balance regulator body used for cooperating with the bottom end of a gas collecting measuring cylinder in a sealed mode to conduct drainage and gas collection, the pressure balance regulator body is internally provided with a gas inlet channel used for introducing gas into the gas collecting measuring cylinder, the gas inlet channel contains a capillary tube section, and the gas inlet channel is internally connected with an external one-way valve; the pressure balance regulator body is further internally provided with a water storage cavity and a drainage channel used for draining water drained by the gas collecting measuring cylinder into the water storage cavity; one side of the water storage cavity is further provided with a water outlet nozzle. According to the gas-liquid pressure balance regulator and the water draining and gas collecting device with the same, a design concept of not adopting conduits is adopted, namely collection and measurement of gas on the basis of the drainage method are achieved without adopting conduits for connection; the high precision is ensured, and meanwhile, the portability and operability of the regulator are improved; moreover, by using water in the water storage cavity to cool high-temperature gas, interference caused by vapour on experimental precision is eliminated, and suck-back or siphonage phenomena resulted from unstable air pressure in a pipeline or excessively high gas flow rate can be avoided.

Description

technical field [0001] The invention relates to the field of gas measuring equipment by the drainage method, in particular to an end-face-sealed gas-liquid pressure balance regulator with gas cooling function and a drainage gas collection device including the regulator. Background technique [0002] As the current mainstream gas collection and measurement method, the drainage method has the characteristics of low cost, intuitive effect, and easy learning. Parts, the required parts are more complicated. At the same time, the collection of gas is carried out underwater, which requires repeated manual operations, and the labor is highly repetitive. There are many disadvantages in the measurement of drainage and gas collection using conventional equipment, for example: (1) the residual air in the conduit will pollute the collected gas, which will affect the determination of gas components in the later stage; (2) when the collected gas is mixed with When there is water vapor, t...
