Abstract

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.

Example Embodiment

[0012] The present invention will be further explained based on the drawings.
[0013] figure 1 The spherical combined gas filter shown includes a low-position shell 1, a front sand core 2, a branch pipe 3, a valve 4, a rear sand core 5 and an upper shell 6. The lower shell 1 and the upper shell 6 are both spherical glass products. The flat front sand core 2 is located in the inner cavity of the lower shell 1 and sintered into an integral body with the inner wall. The upper and lower ends of the lower shell 1 are respectively provided with communication Connect 1.1 and channel 1.2 of the inner cavity. The back sand core 5 is erected in the inner cavity of the upper shell 6 and sintered into one body with the inner wall. The left and right ends of the upper shell 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 in series with the valve 4, and the inner end of the branch pipe 3 is connected with the channel 1.2 of the lower housing 1 and the channel 6.2 of the upper housing 6 to form a controllable three-way pipe structure. In the present invention, the front sand core 2 and the rear sand core 5 are both disc-shaped honeycomb ceramic sheets, and the front sand core 2 is used for primary filtration. The micropores are set to be relatively thicker, and the micropores are between 200 and 400. cm 2 The most suitable, the back sand core 5 is used for the last filtration, the pores are set to be relatively small, and the pores are 400~500/cm 2 The most suitable. This example is used to determine the sulfur content of the No. 0 diesel sample. Due to the high detection accuracy requirements, first, close the valve 4 to form a double-chamber filter united structure, because the micropores of the front sand core 2 are 250-300/cm 2 , The micro-holes of the sand core 5 in the rear track are 450~500/cm 2 , The use of the above two sand core sequential filtration can meet the measurement accuracy requirements.
[0014] In actual use, the gas produced by the combustion of No. 0 diesel fuel sample is introduced from the interface 1.1 of the lower shell 1, filtered by the front sand core 2 and then sequentially enters the inner cavity of the upper shell 6 from the channel 1.2 and the channel 6.2. The rear sand core 5 is filtered and discharged from the interface 6.1, and then the filtered sulfur element is collected from the two sand cores.
[0015] In the present invention, the valve 3 can also be opened, and the cracked gas can be introduced from the interface 1.1 or the interface 6.1 for separate filtration treatment according to the requirements of the measurement sample accuracy.
