Abstract

The invention provides a sealed integrated smoke collection test device. The sealed integrated smoke collection test device comprises a sampling hole substrate, an outer sleeve, a smoke sampling pipe, a thermoelectric couple and an annular sealing disc, wherein the sampling hole substrate is arranged in a sampling hole of a to-be-tested flue, and the sampling hole substrate is provided with a through hole which is communicated with the to-be-tested flue; the outer diameter of the outer sleeve is smaller than the inner diameter of the through hole of the sampling hole substrate; the smoke sampling pipe is arranged in the outer sleeve; the thermoelectric couple is pre-installed outside the smoke sampling pipe and arranged in the outer sleeve; the annular sealing disc is sleeved outside the outer sleeve, the sealing disc is in sealing connection with the outer sleeve, and the outer diameter of the sealing disc is greater than the inner diameter of the through hole of the sampling hole substrate. By adopting the sealed integrated smoke collection test device, the influence of leaked air from the sampling hole on a test of smoke components and a temperature test can be well solved, the use is convenient, a great amount of in-situ installation and length calibration work can be saved, the test time can be saved, and the test efficiency and the test precision can be improved.

Description

technical field [0001] The invention relates to the field of flue gas measurement, in particular to an integrated flue gas collection and testing device with a seal. Background technique [0002] Flue gas composition test and temperature test are necessary test contents in the performance test of power plant boilers. The flue gas composition refers to the mixed gas generated after pulverized coal is burned in the furnace. The main components include: O2, CO2, SO2, CO, NOx, N2, etc. [0003] According to the provisions of the national standard GB10184-88 "Performance Test Regulations for Power Station Boilers", the measurement of flue gas temperature and flue gas composition must be carried out by using the multi-point measurement grid method. The flue gas temperature of utility boilers is usually measured with thermocouples, including T-type thermocouples and K-type thermocouples. The grid method multi-point measurement means that in any flue section perpendicular to the f...
