Integrated smoke and dust sampling device

Abstract

The invention relates to the technical field of smoke and dust sampling, and discloses an integrated smoke and dust sampling device. The device comprises a flue and an electric telescopic rod main body, wherein the bottom surface of the electric telescopic rod main body is in contact with the ground, and the top surface of the output end of the electric telescopic rod main body is fixedly connected with the bottom surface of a fixed column. According to the integrated smoke and dust sampling device, the nozzle head is arranged to be narrow in the lower portion and wide in the upper portion, the nozzle head is not blocked after smoke and dust enter the nozzle head, and sampling work failure caused by dust blocking of the sampling nozzle can be effectively avoided; the sampling device can automatically reach a flue sampling opening by using the electric telescopic rod main body, manual lifting is not needed, the labor force is reduced, and the labor cost is saved; high-temperature cleanairflow is used for heating the sampling pipe by using a heating box, so that the high-temperature sampling airflow containing moisture does not generate condensed water due to low temperature of thesampling pipe, the weight of filtered smoke and dust is not changed, the sampling result is not influenced, and the accuracy and reliability of the sampling result are ensured.

Description

technical field [0001] The invention relates to the technical field of smoke and dust sampling, in particular to a smoke and dust integrated sampling device. Background technique [0002] In the field of environmental monitoring, dust and flue gas sampling and detection are required for fixed pollution sources such as flue ducts. During the sampling process, due to the harsh environmental conditions of the flue sampling platform, it is necessary to manually operate the smoke sampling pipe for a long time to keep it still. Moisture is easy to condense into water droplets. When a large number of water droplets gather in the sampling gun, some of the water droplets will carry impurities and adhere to the filter cartridge of the smoke sampling device, contaminate the sampling filter cartridge, and make the filter cartridge damp, resulting in the collection in the sampling filter cartridge. The weight of the soot sample changes, which makes the sampling result abnormal and direc...

During the sampling process, due to the harsh environmental conditions of the flue sampling platform, it is necessary to manually operate the smoke sampling pipe for a long time to keep it still. Moisture is easy to condense into water droplets. When a large number of water droplets gather in the sampling gun, some of the water droplets will carry impurities and adhere to the filter cartridge of the smoke sampling device, contaminate the sampling filter cartridge, and make the filter cartridge damp, resulting in the collection in the sampling filter cartridge. The weight of the soot sample changes, which makes the sampling result abnormal and directly leads to the failure of the soot sampling test.
