Maintenance-free high-temperature gas sampling probe

Abstract

The invention relates to the technical field of high-temperature gas sampling devices and in particular relates to a maintenance-free high-temperature gas sampling probe which can be maintained without interrupting the sampling and can be used for effectively removing crust at a sampling opening. The maintenance-free high-temperature gas sampling probe consists of a clamping type cooling shell tube, a striking head assembly, a gas sampling pipe and a striking head driving assembly which are sequentially nested, the striking head assembly can be driven by a drive cylinder so as to carry out reciprocating motion and remove the crust of the sampling opening, and the crust at the front end of the probe is removed by a mechanical crust-removing striking head, thus the maintenance-free usage ofthe high-temperature probe is realized, the sampling interruption caused by frequent blowing is avoided, the purpose of long-term continuous and uninterruptible sampling under high-temperature and much-dust environment is realized, the maintenance-free usage of the probe is realized, and the precision of SO2 sampling is also greatly improved.

Description

technical field [0001] The invention relates to the technical field of high-temperature gas sampling equipment, in particular to a high-temperature gas sampling probe. Background technique [0002] The high-temperature sampling probe is a special probe for sampling of the high-temperature gas process analyzer system at the kiln tail of the new dry-process cement rotary kiln or the kiln tail of the lime kiln in the smelter. The high-temperature gas process analyzer system analyzes the composition of the gas in the process through the high-temperature sampling probe. The operator monitors the combustion situation in the rotary kiln through the content of each component, and optimizes the combustion by adjusting the air volume and fuel consumption to achieve stable quality and energy saving. the goal of. This requires the high temperature sampling probe to be able to take samples continuously and uninterruptedly for a long time without distortion. [0003] The condition of th...

AI Technical Summary

Problems solved by technology

When the process sample gas passes through the crust, some components in the sample gas will be absorbed by the crust, especially SO2, which will cause analysis distortion. If the crust is not cleaned in time, dust and low-melting particles will continue to Coalescence, and eventually the sample gas port will be completely blocked

However, the current method of blowing with compressed air cannot effectively remove the crust on the sampling port
