Problems solved by technology

If you want to know the concentration and particle size distribution of fly ash on the cross section, you need to sample multiple points on the cross section separately, which is not only time-consuming and laborious, but also the operating conditions are changing. If you do not sample at the same time, the representativeness of the obtained data is poor.

Abstract

A bamboo joint rotary cover particle sampler is to apply multisertion bamboo joint structure for its tube with long and narrow orifice covered by an arc rotary cover, a hand through its arc outer end controls the open or cover of the orifice, low part of the tube supported by a bracket and pulley can be pushed in or pulled out from the tube to finish multipoint sampling with the best advantage of realizing sampling at the same time.

Description

Technical field: [0001] The invention relates to a particle sampler, in particular to a bamboo-shaped screw cap type particle sampler, which is used for sampling solid particles in the gas flow of pipelines of boilers and chemical equipment, and belongs to the technical field of thermal energy engineering. Background technique: [0002] Gas-solid two-phase flow exists in boilers, chemical equipment and their pipelines, and it is often necessary to sample the solid particles in the gas flow in the process. Taking the boiler as an example, fly ash sampling needs to be carried out in different parts of the boiler body and in the flue to understand the fly ash concentration, particle size distribution, carbon content analysis, etc. Existing fly ash sampling guns can only sample one point on the section. If you want to know the fly ash concentration and particle size distribution on the cross section, you need to sample multiple points on the cross section separately, which is n...
