Abstract

The invention discloses a flue gas sampling and fly ash capturing device capable of being assembled / disassembled quickly. The device mainly comprises a front rack, a filter cylinder joint, a filter cylinder, an outer cylinder, a rear rack, a guide rod, an extension spring, a locking mechanism, a heating rod, a thermocouple, a sealing ring A, a sealing ring B, a sealing ring C, a base, and a thermal insulation shell. The extension spring is used for pre-tightening, the sealing mechanisms are used for locking, the filter cylinder can be replaced rapidly, and the sealing property is guaranteed. A rapid replacing mechanism is adopted, the tedious mechanism such as conventional thread sealing is not used, the assembly and disassembly become convenient, and time is saved.

Description

technical field [0001] The invention belongs to the field of environmental pollution analysis and monitoring, and mainly relates to the sampling and analysis of target pollutants in the flue, in particular to a fly ash trapping device used for the sampling, analysis and monitoring of dioxins in flue gas and dust Background technique [0002] In order to control and reduce air pollution emissions, it is often necessary to sample and monitor fixed pollution sources such as municipal waste incineration, hazardous waste incineration, thermal power plants, steel mills and other industrial furnaces. During the sampling process, the installation and disassembly of the traditional fly ash capture device is cumbersome, which not only increases the sampling time, but also the sealing effect is not very satisfactory, and the operation is not very convenient. Therefore this invention A new fly ash trapping device is proposed, namely A fast loading and unloading flue gas sampling fly ...
