Abstract

The invention relates to the technical field of tail gas removing equipment, and discloses an eddy blowing device for pipelines. The eddy blowing device comprises a blowing device body; a spiral channel is arranged inside the blowing device body; an inlet communicating with a gas inlet of the spiral channel is formed in the upper end face of the blowing device body; and an outlet which communicates with a gas outlet of the spiral channel to provide lateral force and vortex force for blowing the pipelines is formed in the lower end face of the blowing device body. The eddy blowing device has the advantages of being good in blowing effect and capable of achieving automatic blowing.

Description

technical field [0001] The invention relates to the technical field of exhaust gas removal equipment, in particular to a vortex purger used for pipelines. Background technique [0002] At present, with the increasingly stringent emission regulations, the analysis and testing of particulate matter in the exhaust gas of the engine tends to be normal. The sampling pipe of the equipment used to detect the exhaust gas particulate matter and the dilution channel connected with the sampling pipe need to be purged regularly. [0003] There are usually two methods for purging the sampling tube or the dilution channel at present. One way is to use the built-in backflushing function of the equipment to carry out backflushing. However, it is often necessary to consider the maximum pressure bearing capacity of the valve or flow meter on the pipeline during backflushing, so that the purging pressure is limited, resulting in Insufficient purge intensity. Another way is to remove the samp...
