Embodiment Construction
[0012] The present invention will be further described below according to the accompanying drawings.
[0013] figure 1 The spherical conjoined gas filter shown includes a lower casing 1 , a front sand core 2 , a branch pipe 3 , a valve 4 , a rear sand core 5 and an upper casing 6 . Both the lower shell 1 and the upper shell 6 are spherical glass products, the flat front sand core 2 is located in the inner cavity of the lower shell 1 and is sintered into one with the inner wall, and the upper and lower ends of the lower shell 1 are respectively provided with communication Lumen connection 1.1 and channel 1.2. The rear sand core 5 is placed vertically in the inner cavity of the upper casing 6 and is sintered into one body with the inner wall. The left and right ends of the upper casing 6 are respectively provided with an interface 6.1 and a channel 6.2 communicating with the inner cavity. The branch pipe 3 is a round straight pipe, the middle section of which is connected to t...

The invention discloses a spherical integrated type gas filter which comprises a low-position housing, a front way sand core, a valve, a support pipe, a back way sand core and an upper-position housing, wherein the low-position housing and the upper-position housing are respectively to be a spherical glass product, and the front way sand core and the back way sand core are respectively to be a disk-shaped honeycomb ceramic piece. The vertical front way sand core is arranged into the low-position housing and is sintered with an inner wall into a whole to form one independent filter structure. The back way sand core is vertically arranged into an inner cavity of the upper-position housing and is sintered with an inner wall into a whole to form another independent filter structure. The support pipe is connected with the valve in series, and the inner end of the support pipe is connected with a vertical passageway and a passageway of the upper-position housing to form a controllable three-way pipe structure. The spherical integrated type gas filter is a valve-controlled dual-cavity filter integrated structure, is simple in structure, capable of being used for filtering in a dual-cavity classification way, high in filter efficiency, and high in precision, thereby being particularly suitable for the high-precision test of the content of the sulfur element or the nitrogen element of an oil sample.
Description
technical field [0001] The present invention relates to a gas filter, in particular, the present invention relates to a gas filter for electrochemical analysis. Background technique [0002] When the petrochemical industry determines the content of sulfur or nitrogen in petrochemical samples, it usually uses the combustion method to crack the sample, and then introduces the gas generated by the cracking of the tested sample into the filter for filtration, and collects the target elements through filtration. The filter product in the prior art is a single-cavity gas filter structure. The gas filter with this structure is simple in structure, easy to manufacture, convenient to use, and can achieve effective filtration. However, due to structural limitations, the filter in the prior art can only perform one pass of filtration, which is relatively rough and cannot be accurately measured. With the advancement of technology, the quality requirements for petrochemical products are...
