Problems solved by technology

[0003] In the related art, when a gas sampling device is used to sample high-temperature gases with a temperature above 400K (such as combustion chamber gas, vehicle exhaust, etc.), the gas sampling device is easily burned out and has a short service life; and the sampling inlet of the gas sampling device is generally The cylindrical pipe inlet is adopted. When the gas flow rate is not good, the sampling gas introduced at the sampling inlet is less, which cannot accurately reflect the gas composition, resulting in low sampling accuracy.

Abstract

The present invention relates to the technical field of gas sampling, and provides a gas sampling apparatus, which comprises: a shell of a hollow structure, the top of the shell being provided with a cooling water inlet and a cooling water outlet; the sampling pipeline is arranged in the shell and comprises a gas collecting pipe and a plurality of branch pipes, the gas collecting pipe is arranged in the length direction of the shell, and the top end of the gas collecting pipe extends out of the shell and is provided with a sample gas outlet; the plurality of branch pipes are communicated with the side surface of the gas collecting pipe side by side along the length direction of the gas collecting pipe, each branch pipe is provided with a sample gas inlet, the sectional area of the inner surface of the sample gas inlet is gradually reduced along the gas inlet direction, and the sample gas inlet is communicated with the side wall, facing the gas incoming direction, of the shell. The gas sampling device has a cooling effect, can be prevented from being burnt out during sampling work, and can improve the sampling accuracy.

Description

technical field [0001] The invention relates to the technical field of gas sampling, in particular to a gas sampling device. Background technique [0002] The gas sampling device is mainly used to sample the gas, so as to send the collected sample gas to the sample gas analysis device for detection and analysis. [0003] In the related art, when a gas sampling device is used to sample high-temperature gases with a temperature above 400K (such as combustion chamber gas, vehicle exhaust, etc.), the gas sampling device is easily burned out and has a short service life; and the sampling inlet of the gas sampling device is generally The cylindrical pipe inlet is adopted. When the gas flow rate is not good, the sampling gas introduced into the sampling inlet is less, which cannot accurately reflect the gas composition, resulting in low sampling accuracy. Contents of the invention [0004] The invention provides a gas sampling device, which has a better cooling effect, can avoid...
