Gas generator and generation method

Abstract

The invention relates to a gas generator which is used for generating volatile gas and comprises a generator shell, a reaction device, a gas inlet device and a liquid conveying device, a liquid outlet of the liquid conveying device is connected with the reaction device, and a gas source of the gas inlet device is connected to the reaction device through a gas conveying pipe; the reaction device comprises a temperature control module and a reaction module. The temperature control module comprises a heat storage block, a heating rod, a temperature sensor and a temperature controller, and the heat storage block is of a hollow interlayer structure; the temperature sensor is used for detecting the heating temperature of the heat storage block; the temperature controller is used for controlling the temperature of the heating rod according to a detection signal of the temperature sensor; the heating rod is arranged in the hollow interlayer of the heat storage block; the reaction module comprises a gas-liquid mixing pipe, and the gas-liquid mixing pipe is arranged in the hollow interlayer of the heat storage block; and a gas-liquid mixing pipe liquid inlet is formed in the middle of the gas-liquid mixing pipe. The invention also provides a gas generation method. According to the invention, required gas can be accurately and rapidly generated.

Description

technical field [0001] The invention relates to the field of gas generation, in particular to a gas generator. Background technique [0002] With the advancement of science and technology and the improvement of our living standards, more and more people are concerned about environmental pollution and the harm caused by environmental pollution to our bodies. Now the portable instruments for detecting indoor pollutants on the market basically use the sensor method, but the sensor is easy Affected by other pollutants, the performance is non-specific, and the sensor will have a phenomenon of zero point drift, so it is necessary to prepare a standard gas for regular calibration of the sensor. [0003] The known methods for preparing standard gases are mostly through static gas distribution method and dynamic gas distribution method. The static gas distribution method is to add a certain amount of raw material gas into a container of known volume, and then fill it with diluent ga...
