Abstract

The invention relates to a fast flame-retardant solid combustion particle sampling device and sampling steps thereof. The device comprises a sleeve, a filter cylinder and an air pump, wherein the sleeve is communicated with the filter cylinder and the air pump in sequence, the sleeve consists of multiple layers of pipes, one end of the sleeve is a sampling end provided with a blocking plate, everytwo adjacent pipes are connected by an annular plate at the other end of the sleeve, an interlayer is formed between the adjacent pipes by the blocking plate and the annular plates, each interlayer comprises a first chamber, a second chamber and a third chamber from outside to inside, the first chamber is communicated with the second chamber, and through holes communicated with the third chamberare formed in the inner wall, close to the sampling end, of the innermost pipe; a flame retardant gas inlet, a cooling water inlet and a cooling water outlet are formed in the sleeve. One part of theinterlayer chambers formed between the interlayer sleeve tubes are used for discharging inert gas from the sampling end, and the other part of the interlayer chambers are used for cooling inert gas, so that sample distortion due to oxidation and burning of a sample by air during sampling by the sampling device can be avoided.

Description

Technical field: [0001] The invention specifically relates to a fast flame-retardant solid combustion particle sampling device and sampling steps thereof. Background technique: [0002] When studying the characteristics of boiler pulverized coal, it is necessary to take samples in the high-temperature furnace for analysis and research. However, when sampling with conventional sampling devices, the samples will be oxidized and burned due to air, which will distort the obtained samples and result in inaccurate experimental results. , losing the meaning of sampling. Invention content: [0003] In order to overcome the above-mentioned defects, the present invention provides a fast flame-retardant solid combustion particle with simple structure, which can prevent the sample taken out from oxidative combustion in a high-temperature furnace, can represent the real composition structure of the sample, and make the subsequent test results more accurate. Sampling device and its sam...
