Embodiment Construction
[0025] see figure 1 , which is a preferred embodiment of the in-situ integrated gas sample gas processing device, includes a hollow connection seat, a filter membrane 9 is set in the seat cavity of the connection seat, and the filter membrane 9 connects the seat of the connection seat The cavity is divided into an upper seat cavity and a lower seat cavity. In this embodiment, the connecting seat includes a base 8 and an upper cover 10, and the base 8 and the upper cover 10 are threaded to form a detachable connecting seat of a split structure, which is convenient for opening and connecting Seat, adornment, get filter membrane 9. In this embodiment, the filtration accuracy of the filter membrane is 0.05 μm, so that this device can provide high-quality sample gas to the gas analyzer, so that it can realize near-maintenance-free, intrinsically safe, zero-emission in-situ sampling and processing and analysis.
[0026] The lower end of the connecting seat is provided with an oute...

Abstract
The invention discloses an in-situ integral-type gas sample treatment device. The in-situ integral-type gas sample treatment device comprises a connecting seat, wherein a filter film is arranged in a seat cavity of the connecting seat, the filter film seat cavity is divided into an upper seat cavity and a lower seat cavity, the lower end of the connecting seat is provided with an outer barrel and a dewatering filter element, the dewatering filter element is arranged in an outer barrel cavity, a filter cavity of the dewatering filter element is communicated with the lower seat cavity, the lower end of the outer barrel is provided with a lower connecting pipe and a sampling pipe, the sampling pipe is arranged in a hole of the connecting pipe, and a hole of the sampling pipe is communicated with the cavity of the outer barrel; the upper end of the connecting seat is provided with an upper connecting pipe and a sample gas guide pipe, the sample gas guide pipe is arranged in the hole of the upper connecting pipe, and a hole of the sample gas guide pipe is communicated with the upper seat cavity; and the in-situ integral-type gas sample treatment device also comprises a circulating pump, the gas inlet end of the circulating pump is communicated with the upper connecting pipe, and the gas outlet end of the circulating pump is communicated with the lower connecting pipe. The in-situ integral-type gas sample treatment device is simple in structure, low in production cost, easy to install, strong in filter capability, reliable in gas analyzer detection result, little in maintenance and long in service life.
Description
technical field [0001] The invention belongs to the technical field of online gas analysis, and in particular relates to an in-situ integrated gas sample gas processing device. Background technique [0002] The safe production and gas utilization of the coal industry require continuous online monitoring of the gas concentration, the main component of which is methane (CH 4 ). The equipment currently used is a gas online analysis system, which is usually installed on the gas pipeline where the tail cone flowmeter is designed, and the low differential pressure (300-500Pa) upstream and downstream of the tail cone is used for sampling and analysis. There are two connection points between the sampling port and the discharge port, and a connecting pipe needs to be set between the sampling port and the discharge port. [0003] The number of online gas analysis systems currently used in the coal industry is large, but the technical level is very low. The dust filtration ability of...
