Conjoined concatenation type gas absorbing pipe

Abstract

The invention discloses a conjoined concatenation type gas absorbing pipe which consists of a rotating piston, a seal ring, a pipe housing, a medium A, a filter disc and a medium B. The rotating piston is a component of which two ends are respectively provided with an external thread, a middle axial through hole penetrates through the rotating piston, and the inward end face of the rotating piston is provided with a ring-shaped groove to be embedded with the seal ring. The pipe housing is an equant circular pipe, and internal threads arranged at two ends are matched with the large-diameter external thread end of the rotating piston. The filter disc is wafer honeycomb ceramics, wherein the micropore intensity of the filter disc is 200-400 / cm<2>. The filter disc is filled in the middle of the pipe housing to form two cavities, and the medium A and the medium B are respectively filled into each cavity and are connected into a whole through the rotating piston. After the conjoined structure is adopted, two treatment processes of the gas to be tested can be sequentially completed in the process of primary test, so that the test analysis efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a gas absorption tube, in particular to a gas absorption tube for electrochemical analysis of petrochemical samples. Background technique [0002] When electrochemically analyzing the composition content of petrochemical samples, the pyrolysis method is usually used to gasify the petrochemical samples, and the gas absorption tube is required for necessary disposal of the collected gas. The gas absorption tube in the prior art has a single-tube structure, and corresponding absorbing materials can be placed inside the tube according to the function of use. The gas absorbing tube of this structure is simple, easy to manufacture and convenient to install, and can completely process related gases according to the set function. Due to the single function of the products in the prior art, the use is limited, so that the electrochemical analysis process is long and the cost is high. Especially when the gas to be measured has multiple...

Problems solved by technology

Due to the single function of the existing technology products, the use is limited, so that the electrochemical analysis process is long and the cost is high.

Especially when the gas to be measured has multiple processing requirements, it is necessary to connect the gas absorption tubes in series according to the set function sequence. Although this series connection structure can realize the expectation, the measurement efficiency is poor, and the connection joints and installation of the pipelines are doubled. difficulty
