Problems solved by technology

[0003] However, the pressure of some working conditions or experimental environment is relatively high, for example, the pressure of pipeline natural gas can reach 10Mpa, which is far beyond the measurement tolerance range of the above-mentioned analytical instruments. When measuring this high-pressure aerosol, the existing technology The method generally adopted in the test is: pass the measured aerosol through the decompression device to reduce its pressure to the measurement range of the Welas3000 aerosol online analyzer, and then detect it, but due to the

Abstract

The invention discloses a high-pressure aerosol detection conduit, which comprises a pipe body, a high-pressure lens and a lens cover, wherein a through part in the pipe body is used for introducing aerosol to be detected, and a lens mounting hole is formed on the upper part of the pipe body; the high-pressure lens is arranged in the lens mounting hole, the space between the high-pressure lens and the pipe body is sealed by a high pressure resistant sealant, the high-pressure lens is a high pressure resistant glass lens, and the surface of the high-pressure lens is coated with an anti-reflection film; and the lens cover is mounted in the lens mounting hole, covers the outside of the high-pressure lens and has a hole, light rays emitted by an external light source pass through the hole to detect the aerosol in the pipe. The high-pressure aerosol detection conduit can bear aerosol to be tested under a higher pressure to realize the detection of the high-pressure aerosol, and the structure of the high-pressure aerosol detection conduit is simple, and the operation of the high-pressure aerosol detection conduit is easy.

Description

technical field [0001] The invention relates to an aerosol detection catheter, in particular to a high-pressure aerosol detection catheter. Background technique [0002] In the fields of industrial measurement applications or laboratory experiments, online particle analysis of aerosols (including certain gases or gas mixtures) is often required to determine the particle characteristics of the aerosols. However, the online analysis of aerosol particles is more difficult. For the detection of low-concentration aerosols, there is currently a method to use the welas3000 aerosol online detector produced by Palas Company for detection. The aerosol to be measured is passed into the tube, and then the aerosol in the tube is detected by the photoelectric sensors arranged on the periphery. The Welas3000 online aerosol analyzer has the characteristics of high precision and portability. Its measurement temperature range is -90°C to 120°C. The maximum pressure of the catheter is 1Mpa, w...
