Problems solved by technology

At present, the filter cartridges used in conventional monitoring methods, due to the requirements of flue gas isokinetic sampling, the size limit of the filter cartridges and the high content of particulate matter, etc., the monitoring time at the measuring point before the dust collector is short, which is not conducive to the accuracy of the data
The concentration of particulate matter in the flue gas after the...

Abstract

The invention discloses a particulate matter zero loss collecting system. The system comprises a system protective housing, a flue gas sampling gun, a flue gas flow guide pipe and a cyclone dust-removing assembly, wherein the system protective housing is used for protecting the safety of each part of the system; the glue gas sampling gun is connected with the system protective housing through a sampling gun fixing assembly; one end of the flue gas flow guide pipe is connected with the flue gas sampling gun through a connecting piece; a tangential gas inlet of a conical cylinder body is connected with the other end of the flue gas flow guide pipe. The system solves the problem of flue gas particular matter collection before a pollution source dust remover is fixed, and is particularly aimsat a vertical flue measuring hole under the high-dust environment; the cyclone dust-removing assembly is increased, so long-time testing can be conducted and synchronous sampling before and after dustremoval is facilitated; the collection system is compact in structure, modularized and simple and convenient to operate, can change the specification structure according to the actual condition of the flue, and is favorable for carrying out the on-site work and improving the data accuracy.

Description

technical field [0001] The invention relates to the technical field of environmental detection equipment, in particular to a particle zero-loss collection system for testing the content of flue gas and dust from a fixed source. Background technique [0002] When performing a performance test on a fixed pollution source dust collector, it is necessary to test the smoke content before and after the dust collector. Due to the mature technology and superior performance of the existing dust collector, there is a huge difference in the content of flue gas particles before and after the dust collector. According to different types of coal, The particulate matter content in the flue gas before the dust collector can reach several grams to more than ten grams per cubic meter, while the particulate matter content in the flue gas after the dust collector is only about tens to hundreds of milligrams per cubic meter. For the filter cartridges currently used in conventional monitoring met...
